Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

HISTORY:

 

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION:

 

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE:

 

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii) Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

 

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES:

 

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING:

 

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odour.

 

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING:

 

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

 

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION:

 

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

 

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE:

 

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS:

 

ARABIAN:

 

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE:

 

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN:

 

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM:

 

KETORET:

 

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN:

 

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE:

 

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE:

 

PRACTICAL:

 

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC:

 

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS:

 

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE:

 

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material which releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for a variety of purposes, including the ceremonies of religion, to overcome bad smells, repel insects, spirituality, aromatherapy, meditation, and for simple pleasure.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing diversity in the reasons for burning it. Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin for incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense within both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, furnishing tangible archaeological substantiation to the prominence of incense and related compounds within Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300 BCE- 1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the inherited formulation to encompass aromatic roots and other indigenous flora. This comprised the initial usage of subterranean plant parts within the fabrication of incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians for incense.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented instance of incense utilization comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, sandalwood, amongst others) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song Dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th century Shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whomever might take his head in battle). It wasn't until the Muromachi Era during the 15th and 16th century that incense appreciation (Kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

The same could be said for the techniques used to make incense. Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, among them clergy and physicians who were both familiar with incense arts.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

- Fuel and oxidizer mixtures: Charcoal or wood powder forms the fuel for the combustion. Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are combined into the base prior to formation as in the case of powdered incense materials or after formation as in the case of essential oils. The formula for the charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

- Natural plant-based binders: Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. This includes:

- Makko (incense powder): made from the bark of various trees from the Persea such as Persea thunbergii)

- Xiangnan pi (made from the bark of Phoebe genus trees such as Phoebe nanmu, Persea zuihoensis.

- Jigit: a resin based binder used in India

- Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

TYPES

Incense materials are available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types depending on use. Preference for one form or another varies with culture, tradition, and personal taste. Although the production of direct- and indirect-burning incense are both blended to produce a pleasant smell when burned, the two differ in their composition due to the former's requirement for even, stale, and sustained burning.

 

INDIRECT BURNING

Indirect-burning incense, also called "non-combustible incense", is a combination of aromatic ingredients that are not prepared in any particular way or encouraged into any particular form, leaving it mostly unsuitable for direct combustion. The use of this class of incense requires a separate heat source since it does not generally kindle a fire capable of burning itself and may not ignite at all under normal conditions. This incense can vary in the duration of its burning with the texture of the material. Finer ingredients tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually as they have less total surface area. The heat is traditionally provided by charcoal or glowing embers.

 

In the West, the best known incense materials of this type are frankincense and myrrh, likely due to their numerous mentions in the Christian Bible. In fact, the word for "frankincense" in many European languages also alludes to any form of incense.

 

- Whole: The incense material is burned directly in its raw unprocessed form on top of coal embers.

- Powdered or granulated: The incense material is broken down into finer bits. This incense burns quickly and provides a short period of intense smells.

- Paste: The powdered or granulated incense material is mixed with a sticky and incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type (Bakhoor actually refers to frankincense in Arabic) and Japan has a history of kneaded incense, called nerikō or awasekō, using this method.[17] Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT BURNING

Direct-burning incense also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn away the rest of the incense without continued application of heat or flame from an outside source. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types of direct-burning incense are commonly encountered, though the material itself can take virtually any form, according to expediency or whimsy:

 

- Coil: Extruded and shaped into a coil without a core. This type of incense is able to burn for an extended period, from hours to days, and is commonly produced and used by Chinese culture

- Cone: Incense in this form burns relatively fast. Incense cones were invented in Japan in the 1800s.

- Cored stick: This form of stick incense has a supporting core of bamboo. Higher quality varieties of this form have fragrant sandalwood cores. The core is coated by a thick layer of incense material that burns away with the core. This type of incense is commonly produced in India and China. When used for worship in Chinese folk religion, cored incensed sticks are sometimes known as "joss sticks".

- Solid stick: This stick incense has no supporting core and is completely made of incense material. Easily broken into pieces, it allows one to determine the specific amount of incense they wish to burn. This is the most commonly produced form of incense in Japan and Tibet.

- Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. They are typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

- Paper: Paper infused with incense, folded accordion style, lit and blown out. Examples are Carta d'Armenia and Papier d'Arménie.

- Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is highly transportable and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

The disks of powdered mugwort called 'moxa' sold in Chinese shops and herbalists are used in Traditional Chinese medicine for moxibustion treatment. Moxa tablets are not incenses; the treatment relies on heat rather than fragrance.

  

REED DIFFUSING

A reed diffuser is a form of incense that uses no heat. It comes in three parts: a bottle/container, scented essential incense oil, and bamboo reeds. The incense oil is placed into the container and bamboo reeds are then put into the same container. This is done to absorb some of the incense oil, as well as to help carry its scent and essence out of the container and into the surrounding air. Reeds typically have tiny tube openings that run the entire length of the stick. Oil is absorbed by the reed sticks and carried along the entire reed. These are do-it-yourself incense sticks that do not burn and look almost identical to typical incense sticks

 

PRODUCTION

INDIRECT BURNING

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, are then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition are made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

DIRECT BURNING

In order to obtain desired combustion qualities, attention has to be paid to certain proportions in direct burning incense mixtures:

 

- Oil content: Resinous materials such as myrrh and frankincense must not exceed the amount of dry materials in the mixture to such a degree that the incense will not smolder and burn.[citation needed] The higher the oil content relative to the dry mass, the less likely the mixture is to burn effectively.[citation needed] Typically the resinous or oily substances are balanced with "dry" materials such as wood, bark and leaf powders.

- Oxidizer quantity: The amount of chemical oxidizer in gum-bound incense must be carefully proportioned. If too little, the incense will not ignite, and if too much, the incense will burn too quickly and not produce fragrant smoke.

- Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

- Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

- Binder: Water-soluble binders such as "makko" have to be used in the right proportion to ensure that the incense mixture does not crumble when dry but also that the binder does not take up too much of the mixture.

 

Some kinds of direct-burning incense are created from "incense blanks" made of unscented combustible dust immersed into any suitable kind of essential or fragrance oil. These are often sold in America by flea-market and sidewalk vendors who have developed their own styles. Such items are often known as "dipped" or "hand-dipped" incense. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia, then simply scented with essential oils.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo cores of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. Through this process, known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and then continuously split in halves until thin sticks of bamboo with square cross sections of less than 3mm This process has been largely been replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

- Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

- Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are then evenly separated, then dipped into a tray of incense powder, consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the stick while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks that are burned in temples of Chinese folk religion produced in this fashion can have a thickness between 2 and 4 millimeters.

- Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more commonly found due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

JOSS STICKS

Joss sticks are the name given to incense sticks used for a variety of purposes associated with ritual and religious devotion in China and India. They are used in Chinese influenced East Asian and Southeast Asian countries, traditionally burned before the threshold of a home or business, before an image of a Chinese popular religion divinity or spirit of place, or in small and humble or large and elaborate shrine found at the main entrance to each and every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door, or open window as an offering to heaven, or devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

Joss-stick burning is an everyday practice in traditional Chinese religion. There are many different types of joss sticks used for different purposes or on different festive days. Many of them are long and thin and are mostly colored yellow, red, and more rarely, black. Thick joss sticks are used for special ceremonies, such as funerals. Spiral joss sticks are also used on a regular basis, which are found hanging above temple ceilings, with burn times that are exceedingly long. In some states, such as Taiwan, Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon joss sticks are sometimes used. These generate such a massive amount of smoke and heat that they are only ever burned outside.

 

Chinese incense sticks for use in popular religion are generally without aroma or only the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum.[citation needed] Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Despite the fact that they contain no sandalwood at all, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are only used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, aloeswood, or floral scents used. The Sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, Buddhism in Sri Lanka, Buddhism in Burma and Korean Buddhism do not use incense.

 

BURNING INCENSE

For indirect-burning incense, pieces of the incense are burned by placing them directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉?) is used by several Buddhist sects. The egōro is usually made of brass with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as Sonae-kō (Religious Burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. Flames on the incense are then fanned or blown out, with the incense continuing to burn without a flame on its own.

 

CULTURAL VARIATIONS

CHINESE INCENSE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life.

 

Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The poet Yu Jianwu (487-551) first recorded them: "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

 

It is incorrect to assume that the Chinese only burn incense in the home before the family shrine. In Taoist traditions, incense is inextricably associated with the 'yin' energies of the dead, temples, shrines, and ghosts. Therefore, Taoist Chinese believe burning undedicated incense in the home attracts the dreaded hungry ghosts, who consume the smoke and ruin the fortunes of the family.

 

However, since Neolithic times, the Chinese have evolved using incense not only for religious ceremonies, but also for personal and environmental aromatherapy.

 

INDIAN INCENSE

Incense stick, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, is one of the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepal/Tibet and Japanese methods of stick making which don't use a bamboo core. Though the method is also used in the west, particularly in America, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder - an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India which take raw unperfumed sticks hand-rolled by approx 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale.[38] An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 main companies who together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Bangalore.

 

In the Middle East, incense burning has been along tradition. The word bukhur means incense in Arabic. The well known choice for incense is the famous agarwood which is very popular in Africa, the Gulf and amongst some south Asians, but there are many many more choices. Incense come in a variety of forms such as blocks, pieces, pellets, granules or powdered, which is placed in the oil burner called mabkharah for several minutes to heat either with coal in the traditional way or via power in the modern way, allowing it to release its rich smell. However this takes awhile and the quick alternative is to use incense sticks called Oud in Middle East and Africa, and agarbatti in south Asia - again referring to the agar wood + batti meaning some sort of agar-stick. Occasionally some get confused between bukhur and oud, bukhur is the insence ie agarwood, sandlewood etc and oud being the incense sticks (and not the otherway round sometimes wires get twisted)

 

JERUSALEM TEMPLE INCENSE

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus as a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN INCENSE

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, or sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE INCENSE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like Calligraphy, Ikebana, and Scroll Arrangement. However the art of incense appreciation or Koh-do, is generally practiced as a separate art form from the tea ceremony, however usually practiced within a tea room of traditional Zen design.

 

Agarwood (沈香　Jinkō) and sandalwood (白檀　Byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "Jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation.[citation needed] It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

- Incense Arts: [香道, Kodo]

- Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

- Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

- Charcoal: [木炭] – only the odorless kind is used.

- Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

Incense is used for a variety of purposes, including the ceremonies of all the main religions, to overcome bad smells, repel insects, purify or improve the atmosphere, aromatherapy, meditation, and for simple pleasure.

 

PRACTICAL

Incense fragrances can be of such great strength that they obscure other, less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. Another example of this use, as well as of religious use, is the giant Botafumeiro thurible which swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single, long handle on one side. It is important to note that the perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct combustion incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve and captivate several of the senses.

 

Incense made from materials such as citronella can repel mosquitoes and other aggravating, distracting or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors, and do not want the scent to linger.

 

AestheticMany people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the refined sensory experience. This use is perhaps best exemplified in the kōdō (香道?), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.ReligiousUse of incense in religion is prevalent in many cultures and may have their roots in the practical and aesthetic uses considering that many religions with not much else in common all use incense. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense [to ancestors/gods]), etc.

 

HEALTH

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and absorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. The emission rate decreases in the row Indian sandalwood > Japanese aloeswood > Taiwanese aloeswood > smokeless sandalwood.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, a study by several Asian Cancer Research Centers showed: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified the findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and cancer of the lung, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also had higher rates of a type of cancer called squamous-cell carcinoma, which refers to tumors that arise in the cells lining the internal and external surfaces of the body. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters ovary cells to be even higher than cigarettes.

 

Frankincense has been shown to cause antidepressive behavior in mice. It activated the poorly understood ion channels in the brain to alleviate anxiety and depression.

 

WIKIPEDIA

Incense is aromatic biotic material which releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for a variety of purposes, including the ceremonies of religion, to overcome bad smells, repel insects, spirituality, aromatherapy, meditation, and for simple pleasure.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing diversity in the reasons for burning it. Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin for incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense within both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, furnishing tangible archaeological substantiation to the prominence of incense and related compounds within Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300 BCE- 1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the inherited formulation to encompass aromatic roots and other indigenous flora. This comprised the initial usage of subterranean plant parts within the fabrication of incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians for incense.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented instance of incense utilization comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, sandalwood, amongst others) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song Dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th century Shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whomever might take his head in battle). It wasn't until the Muromachi Era during the 15th and 16th century that incense appreciation (Kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

The same could be said for the techniques used to make incense. Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, among them clergy and physicians who were both familiar with incense arts.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

- Fuel and oxidizer mixtures: Charcoal or wood powder forms the fuel for the combustion. Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are combined into the base prior to formation as in the case of powdered incense materials or after formation as in the case of essential oils. The formula for the charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

- Natural plant-based binders: Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. This includes:

- Makko (incense powder): made from the bark of various trees from the Persea such as Persea thunbergii)

- Xiangnan pi (made from the bark of Phoebe genus trees such as Phoebe nanmu, Persea zuihoensis.

- Jigit: a resin based binder used in India

- Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

TYPES

Incense materials are available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types depending on use. Preference for one form or another varies with culture, tradition, and personal taste. Although the production of direct- and indirect-burning incense are both blended to produce a pleasant smell when burned, the two differ in their composition due to the former's requirement for even, stale, and sustained burning.

 

INDIRECT BURNING

Indirect-burning incense, also called "non-combustible incense", is a combination of aromatic ingredients that are not prepared in any particular way or encouraged into any particular form, leaving it mostly unsuitable for direct combustion. The use of this class of incense requires a separate heat source since it does not generally kindle a fire capable of burning itself and may not ignite at all under normal conditions. This incense can vary in the duration of its burning with the texture of the material. Finer ingredients tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually as they have less total surface area. The heat is traditionally provided by charcoal or glowing embers.

 

In the West, the best known incense materials of this type are frankincense and myrrh, likely due to their numerous mentions in the Christian Bible. In fact, the word for "frankincense" in many European languages also alludes to any form of incense.

 

- Whole: The incense material is burned directly in its raw unprocessed form on top of coal embers.

- Powdered or granulated: The incense material is broken down into finer bits. This incense burns quickly and provides a short period of intense smells.

- Paste: The powdered or granulated incense material is mixed with a sticky and incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type (Bakhoor actually refers to frankincense in Arabic) and Japan has a history of kneaded incense, called nerikō or awasekō, using this method.[17] Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT BURNING

Direct-burning incense also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn away the rest of the incense without continued application of heat or flame from an outside source. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types of direct-burning incense are commonly encountered, though the material itself can take virtually any form, according to expediency or whimsy:

 

- Coil: Extruded and shaped into a coil without a core. This type of incense is able to burn for an extended period, from hours to days, and is commonly produced and used by Chinese culture

- Cone: Incense in this form burns relatively fast. Incense cones were invented in Japan in the 1800s.

- Cored stick: This form of stick incense has a supporting core of bamboo. Higher quality varieties of this form have fragrant sandalwood cores. The core is coated by a thick layer of incense material that burns away with the core. This type of incense is commonly produced in India and China. When used for worship in Chinese folk religion, cored incensed sticks are sometimes known as "joss sticks".

- Solid stick: This stick incense has no supporting core and is completely made of incense material. Easily broken into pieces, it allows one to determine the specific amount of incense they wish to burn. This is the most commonly produced form of incense in Japan and Tibet.

- Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. They are typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

- Paper: Paper infused with incense, folded accordion style, lit and blown out. Examples are Carta d'Armenia and Papier d'Arménie.

- Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is highly transportable and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

The disks of powdered mugwort called 'moxa' sold in Chinese shops and herbalists are used in Traditional Chinese medicine for moxibustion treatment. Moxa tablets are not incenses; the treatment relies on heat rather than fragrance.

  

REED DIFFUSING

A reed diffuser is a form of incense that uses no heat. It comes in three parts: a bottle/container, scented essential incense oil, and bamboo reeds. The incense oil is placed into the container and bamboo reeds are then put into the same container. This is done to absorb some of the incense oil, as well as to help carry its scent and essence out of the container and into the surrounding air. Reeds typically have tiny tube openings that run the entire length of the stick. Oil is absorbed by the reed sticks and carried along the entire reed. These are do-it-yourself incense sticks that do not burn and look almost identical to typical incense sticks

 

PRODUCTION

INDIRECT BURNING

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, are then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition are made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

DIRECT BURNING

In order to obtain desired combustion qualities, attention has to be paid to certain proportions in direct burning incense mixtures:

 

- Oil content: Resinous materials such as myrrh and frankincense must not exceed the amount of dry materials in the mixture to such a degree that the incense will not smolder and burn.[citation needed] The higher the oil content relative to the dry mass, the less likely the mixture is to burn effectively.[citation needed] Typically the resinous or oily substances are balanced with "dry" materials such as wood, bark and leaf powders.

- Oxidizer quantity: The amount of chemical oxidizer in gum-bound incense must be carefully proportioned. If too little, the incense will not ignite, and if too much, the incense will burn too quickly and not produce fragrant smoke.

- Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

- Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

- Binder: Water-soluble binders such as "makko" have to be used in the right proportion to ensure that the incense mixture does not crumble when dry but also that the binder does not take up too much of the mixture.

 

Some kinds of direct-burning incense are created from "incense blanks" made of unscented combustible dust immersed into any suitable kind of essential or fragrance oil. These are often sold in America by flea-market and sidewalk vendors who have developed their own styles. Such items are often known as "dipped" or "hand-dipped" incense. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia, then simply scented with essential oils.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo cores of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. Through this process, known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and then continuously split in halves until thin sticks of bamboo with square cross sections of less than 3mm This process has been largely been replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

- Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

- Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are then evenly separated, then dipped into a tray of incense powder, consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the stick while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks that are burned in temples of Chinese folk religion produced in this fashion can have a thickness between 2 and 4 millimeters.

- Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more commonly found due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

JOSS STICKS

Joss sticks are the name given to incense sticks used for a variety of purposes associated with ritual and religious devotion in China and India. They are used in Chinese influenced East Asian and Southeast Asian countries, traditionally burned before the threshold of a home or business, before an image of a Chinese popular religion divinity or spirit of place, or in small and humble or large and elaborate shrine found at the main entrance to each and every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door, or open window as an offering to heaven, or devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

Joss-stick burning is an everyday practice in traditional Chinese religion. There are many different types of joss sticks used for different purposes or on different festive days. Many of them are long and thin and are mostly colored yellow, red, and more rarely, black. Thick joss sticks are used for special ceremonies, such as funerals. Spiral joss sticks are also used on a regular basis, which are found hanging above temple ceilings, with burn times that are exceedingly long. In some states, such as Taiwan, Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon joss sticks are sometimes used. These generate such a massive amount of smoke and heat that they are only ever burned outside.

 

Chinese incense sticks for use in popular religion are generally without aroma or only the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum.[citation needed] Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Despite the fact that they contain no sandalwood at all, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are only used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, aloeswood, or floral scents used. The Sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, Buddhism in Sri Lanka, Buddhism in Burma and Korean Buddhism do not use incense.

 

BURNING INCENSE

For indirect-burning incense, pieces of the incense are burned by placing them directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉?) is used by several Buddhist sects. The egōro is usually made of brass with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as Sonae-kō (Religious Burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. Flames on the incense are then fanned or blown out, with the incense continuing to burn without a flame on its own.

 

CULTURAL VARIATIONS

CHINESE INCENSE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life.

 

Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The poet Yu Jianwu (487-551) first recorded them: "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

 

It is incorrect to assume that the Chinese only burn incense in the home before the family shrine. In Taoist traditions, incense is inextricably associated with the 'yin' energies of the dead, temples, shrines, and ghosts. Therefore, Taoist Chinese believe burning undedicated incense in the home attracts the dreaded hungry ghosts, who consume the smoke and ruin the fortunes of the family.

 

However, since Neolithic times, the Chinese have evolved using incense not only for religious ceremonies, but also for personal and environmental aromatherapy.

 

INDIAN INCENSE

Incense stick, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, is one of the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepal/Tibet and Japanese methods of stick making which don't use a bamboo core. Though the method is also used in the west, particularly in America, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder - an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India which take raw unperfumed sticks hand-rolled by approx 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale.[38] An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 main companies who together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Bangalore.

 

In the Middle East, incense burning has been along tradition. The word bukhur means incense in Arabic. The well known choice for incense is the famous agarwood which is very popular in Africa, the Gulf and amongst some south Asians, but there are many many more choices. Incense come in a variety of forms such as blocks, pieces, pellets, granules or powdered, which is placed in the oil burner called mabkharah for several minutes to heat either with coal in the traditional way or via power in the modern way, allowing it to release its rich smell. However this takes awhile and the quick alternative is to use incense sticks called Oud in Middle East and Africa, and agarbatti in south Asia - again referring to the agar wood + batti meaning some sort of agar-stick. Occasionally some get confused between bukhur and oud, bukhur is the insence ie agarwood, sandlewood etc and oud being the incense sticks (and not the otherway round sometimes wires get twisted)

 

JERUSALEM TEMPLE INCENSE

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus as a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN INCENSE

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, or sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE INCENSE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like Calligraphy, Ikebana, and Scroll Arrangement. However the art of incense appreciation or Koh-do, is generally practiced as a separate art form from the tea ceremony, however usually practiced within a tea room of traditional Zen design.

 

Agarwood (沈香　Jinkō) and sandalwood (白檀　Byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "Jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation.[citation needed] It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

- Incense Arts: [香道, Kodo]

- Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

- Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

- Charcoal: [木炭] – only the odorless kind is used.

- Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

Incense is used for a variety of purposes, including the ceremonies of all the main religions, to overcome bad smells, repel insects, purify or improve the atmosphere, aromatherapy, meditation, and for simple pleasure.

 

PRACTICAL

Incense fragrances can be of such great strength that they obscure other, less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. Another example of this use, as well as of religious use, is the giant Botafumeiro thurible which swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single, long handle on one side. It is important to note that the perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct combustion incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve and captivate several of the senses.

 

Incense made from materials such as citronella can repel mosquitoes and other aggravating, distracting or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors, and do not want the scent to linger.

 

AestheticMany people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the refined sensory experience. This use is perhaps best exemplified in the kōdō (香道?), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.ReligiousUse of incense in religion is prevalent in many cultures and may have their roots in the practical and aesthetic uses considering that many religions with not much else in common all use incense. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense [to ancestors/gods]), etc.

 

HEALTH

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and absorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. The emission rate decreases in the row Indian sandalwood > Japanese aloeswood > Taiwanese aloeswood > smokeless sandalwood.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, a study by several Asian Cancer Research Centers showed: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified the findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and cancer of the lung, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also had higher rates of a type of cancer called squamous-cell carcinoma, which refers to tumors that arise in the cells lining the internal and external surfaces of the body. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters ovary cells to be even higher than cigarettes.

 

Frankincense has been shown to cause antidepressive behavior in mice. It activated the poorly understood ion channels in the brain to alleviate anxiety and depression.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material which releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for a variety of purposes, including the ceremonies of religion, to overcome bad smells, repel insects, spirituality, aromatherapy, meditation, and for simple pleasure.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing diversity in the reasons for burning it. Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin for incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense within both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, furnishing tangible archaeological substantiation to the prominence of incense and related compounds within Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300 BCE- 1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the inherited formulation to encompass aromatic roots and other indigenous flora. This comprised the initial usage of subterranean plant parts within the fabrication of incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians for incense.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented instance of incense utilization comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, sandalwood, amongst others) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song Dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th century Shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whomever might take his head in battle). It wasn't until the Muromachi Era during the 15th and 16th century that incense appreciation (Kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

The same could be said for the techniques used to make incense. Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, among them clergy and physicians who were both familiar with incense arts.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

- Fuel and oxidizer mixtures: Charcoal or wood powder forms the fuel for the combustion. Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are combined into the base prior to formation as in the case of powdered incense materials or after formation as in the case of essential oils. The formula for the charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

- Natural plant-based binders: Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. This includes:

- Makko (incense powder): made from the bark of various trees from the Persea such as Persea thunbergii)

- Xiangnan pi (made from the bark of Phoebe genus trees such as Phoebe nanmu, Persea zuihoensis.

- Jigit: a resin based binder used in India

- Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

TYPES

Incense materials are available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types depending on use. Preference for one form or another varies with culture, tradition, and personal taste. Although the production of direct- and indirect-burning incense are both blended to produce a pleasant smell when burned, the two differ in their composition due to the former's requirement for even, stale, and sustained burning.

 

INDIRECT BURNING

Indirect-burning incense, also called "non-combustible incense", is a combination of aromatic ingredients that are not prepared in any particular way or encouraged into any particular form, leaving it mostly unsuitable for direct combustion. The use of this class of incense requires a separate heat source since it does not generally kindle a fire capable of burning itself and may not ignite at all under normal conditions. This incense can vary in the duration of its burning with the texture of the material. Finer ingredients tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually as they have less total surface area. The heat is traditionally provided by charcoal or glowing embers.

 

In the West, the best known incense materials of this type are frankincense and myrrh, likely due to their numerous mentions in the Christian Bible. In fact, the word for "frankincense" in many European languages also alludes to any form of incense.

 

- Whole: The incense material is burned directly in its raw unprocessed form on top of coal embers.

- Powdered or granulated: The incense material is broken down into finer bits. This incense burns quickly and provides a short period of intense smells.

- Paste: The powdered or granulated incense material is mixed with a sticky and incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type (Bakhoor actually refers to frankincense in Arabic) and Japan has a history of kneaded incense, called nerikō or awasekō, using this method.[17] Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT BURNING

Direct-burning incense also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn away the rest of the incense without continued application of heat or flame from an outside source. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types of direct-burning incense are commonly encountered, though the material itself can take virtually any form, according to expediency or whimsy:

 

- Coil: Extruded and shaped into a coil without a core. This type of incense is able to burn for an extended period, from hours to days, and is commonly produced and used by Chinese culture

- Cone: Incense in this form burns relatively fast. Incense cones were invented in Japan in the 1800s.

- Cored stick: This form of stick incense has a supporting core of bamboo. Higher quality varieties of this form have fragrant sandalwood cores. The core is coated by a thick layer of incense material that burns away with the core. This type of incense is commonly produced in India and China. When used for worship in Chinese folk religion, cored incensed sticks are sometimes known as "joss sticks".

- Solid stick: This stick incense has no supporting core and is completely made of incense material. Easily broken into pieces, it allows one to determine the specific amount of incense they wish to burn. This is the most commonly produced form of incense in Japan and Tibet.

- Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. They are typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

- Paper: Paper infused with incense, folded accordion style, lit and blown out. Examples are Carta d'Armenia and Papier d'Arménie.

- Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is highly transportable and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

The disks of powdered mugwort called 'moxa' sold in Chinese shops and herbalists are used in Traditional Chinese medicine for moxibustion treatment. Moxa tablets are not incenses; the treatment relies on heat rather than fragrance.

  

REED DIFFUSING

A reed diffuser is a form of incense that uses no heat. It comes in three parts: a bottle/container, scented essential incense oil, and bamboo reeds. The incense oil is placed into the container and bamboo reeds are then put into the same container. This is done to absorb some of the incense oil, as well as to help carry its scent and essence out of the container and into the surrounding air. Reeds typically have tiny tube openings that run the entire length of the stick. Oil is absorbed by the reed sticks and carried along the entire reed. These are do-it-yourself incense sticks that do not burn and look almost identical to typical incense sticks

 

PRODUCTION

INDIRECT BURNING

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, are then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition are made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

DIRECT BURNING

In order to obtain desired combustion qualities, attention has to be paid to certain proportions in direct burning incense mixtures:

 

- Oil content: Resinous materials such as myrrh and frankincense must not exceed the amount of dry materials in the mixture to such a degree that the incense will not smolder and burn.[citation needed] The higher the oil content relative to the dry mass, the less likely the mixture is to burn effectively.[citation needed] Typically the resinous or oily substances are balanced with "dry" materials such as wood, bark and leaf powders.

- Oxidizer quantity: The amount of chemical oxidizer in gum-bound incense must be carefully proportioned. If too little, the incense will not ignite, and if too much, the incense will burn too quickly and not produce fragrant smoke.

- Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

- Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

- Binder: Water-soluble binders such as "makko" have to be used in the right proportion to ensure that the incense mixture does not crumble when dry but also that the binder does not take up too much of the mixture.

 

Some kinds of direct-burning incense are created from "incense blanks" made of unscented combustible dust immersed into any suitable kind of essential or fragrance oil. These are often sold in America by flea-market and sidewalk vendors who have developed their own styles. Such items are often known as "dipped" or "hand-dipped" incense. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia, then simply scented with essential oils.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo cores of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. Through this process, known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and then continuously split in halves until thin sticks of bamboo with square cross sections of less than 3mm This process has been largely been replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

- Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

- Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are then evenly separated, then dipped into a tray of incense powder, consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the stick while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks that are burned in temples of Chinese folk religion produced in this fashion can have a thickness between 2 and 4 millimeters.

- Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more commonly found due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

JOSS STICKS

Joss sticks are the name given to incense sticks used for a variety of purposes associated with ritual and religious devotion in China and India. They are used in Chinese influenced East Asian and Southeast Asian countries, traditionally burned before the threshold of a home or business, before an image of a Chinese popular religion divinity or spirit of place, or in small and humble or large and elaborate shrine found at the main entrance to each and every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door, or open window as an offering to heaven, or devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

Joss-stick burning is an everyday practice in traditional Chinese religion. There are many different types of joss sticks used for different purposes or on different festive days. Many of them are long and thin and are mostly colored yellow, red, and more rarely, black. Thick joss sticks are used for special ceremonies, such as funerals. Spiral joss sticks are also used on a regular basis, which are found hanging above temple ceilings, with burn times that are exceedingly long. In some states, such as Taiwan, Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon joss sticks are sometimes used. These generate such a massive amount of smoke and heat that they are only ever burned outside.

 

Chinese incense sticks for use in popular religion are generally without aroma or only the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum.[citation needed] Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Despite the fact that they contain no sandalwood at all, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are only used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, aloeswood, or floral scents used. The Sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, Buddhism in Sri Lanka, Buddhism in Burma and Korean Buddhism do not use incense.

 

BURNING INCENSE

For indirect-burning incense, pieces of the incense are burned by placing them directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉?) is used by several Buddhist sects. The egōro is usually made of brass with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as Sonae-kō (Religious Burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. Flames on the incense are then fanned or blown out, with the incense continuing to burn without a flame on its own.

 

CULTURAL VARIATIONS

CHINESE INCENSE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life.

 

Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The poet Yu Jianwu (487-551) first recorded them: "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

 

It is incorrect to assume that the Chinese only burn incense in the home before the family shrine. In Taoist traditions, incense is inextricably associated with the 'yin' energies of the dead, temples, shrines, and ghosts. Therefore, Taoist Chinese believe burning undedicated incense in the home attracts the dreaded hungry ghosts, who consume the smoke and ruin the fortunes of the family.

 

However, since Neolithic times, the Chinese have evolved using incense not only for religious ceremonies, but also for personal and environmental aromatherapy.

 

INDIAN INCENSE

Incense stick, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, is one of the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepal/Tibet and Japanese methods of stick making which don't use a bamboo core. Though the method is also used in the west, particularly in America, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder - an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India which take raw unperfumed sticks hand-rolled by approx 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale.[38] An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 main companies who together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Bangalore.

 

In the Middle East, incense burning has been along tradition. The word bukhur means incense in Arabic. The well known choice for incense is the famous agarwood which is very popular in Africa, the Gulf and amongst some south Asians, but there are many many more choices. Incense come in a variety of forms such as blocks, pieces, pellets, granules or powdered, which is placed in the oil burner called mabkharah for several minutes to heat either with coal in the traditional way or via power in the modern way, allowing it to release its rich smell. However this takes awhile and the quick alternative is to use incense sticks called Oud in Middle East and Africa, and agarbatti in south Asia - again referring to the agar wood + batti meaning some sort of agar-stick. Occasionally some get confused between bukhur and oud, bukhur is the insence ie agarwood, sandlewood etc and oud being the incense sticks (and not the otherway round sometimes wires get twisted)

 

JERUSALEM TEMPLE INCENSE

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus as a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN INCENSE

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, or sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE INCENSE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like Calligraphy, Ikebana, and Scroll Arrangement. However the art of incense appreciation or Koh-do, is generally practiced as a separate art form from the tea ceremony, however usually practiced within a tea room of traditional Zen design.

 

Agarwood (沈香　Jinkō) and sandalwood (白檀　Byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "Jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation.[citation needed] It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

- Incense Arts: [香道, Kodo]

- Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

- Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

- Charcoal: [木炭] – only the odorless kind is used.

- Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

Incense is used for a variety of purposes, including the ceremonies of all the main religions, to overcome bad smells, repel insects, purify or improve the atmosphere, aromatherapy, meditation, and for simple pleasure.

 

PRACTICAL

Incense fragrances can be of such great strength that they obscure other, less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. Another example of this use, as well as of religious use, is the giant Botafumeiro thurible which swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single, long handle on one side. It is important to note that the perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct combustion incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve and captivate several of the senses.

 

Incense made from materials such as citronella can repel mosquitoes and other aggravating, distracting or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors, and do not want the scent to linger.

 

AestheticMany people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the refined sensory experience. This use is perhaps best exemplified in the kōdō (香道?), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.ReligiousUse of incense in religion is prevalent in many cultures and may have their roots in the practical and aesthetic uses considering that many religions with not much else in common all use incense. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense [to ancestors/gods]), etc.

 

HEALTH

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and absorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. The emission rate decreases in the row Indian sandalwood > Japanese aloeswood > Taiwanese aloeswood > smokeless sandalwood.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, a study by several Asian Cancer Research Centers showed: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified the findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and cancer of the lung, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also had higher rates of a type of cancer called squamous-cell carcinoma, which refers to tumors that arise in the cells lining the internal and external surfaces of the body. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters ovary cells to be even higher than cigarettes.

 

Frankincense has been shown to cause antidepressive behavior in mice. It activated the poorly understood ion channels in the brain to alleviate anxiety and depression.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY:

 

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION:

 

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE:

 

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii) Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES:

 

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING:

 

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odour.

 

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING:

 

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

 

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

 

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION:

 

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

 

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

 

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

 

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

 

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE:

 

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS:

 

ARABIAN:

 

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE:

 

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN:

 

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM:

 

KETORET:

 

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN:

 

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE:

 

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE:

 

PRACTICAL:

 

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC:

 

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS:

 

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE:

 

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material which releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for a variety of purposes, including the ceremonies of religion, to overcome bad smells, repel insects, spirituality, aromatherapy, meditation, and for simple pleasure.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing diversity in the reasons for burning it. Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin for incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense within both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, furnishing tangible archaeological substantiation to the prominence of incense and related compounds within Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300 BCE- 1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the inherited formulation to encompass aromatic roots and other indigenous flora. This comprised the initial usage of subterranean plant parts within the fabrication of incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians for incense.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented instance of incense utilization comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, sandalwood, amongst others) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song Dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th century Shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whomever might take his head in battle). It wasn't until the Muromachi Era during the 15th and 16th century that incense appreciation (Kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

The same could be said for the techniques used to make incense. Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, among them clergy and physicians who were both familiar with incense arts.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

- Fuel and oxidizer mixtures: Charcoal or wood powder forms the fuel for the combustion. Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are combined into the base prior to formation as in the case of powdered incense materials or after formation as in the case of essential oils. The formula for the charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

- Natural plant-based binders: Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. This includes:

- Makko (incense powder): made from the bark of various trees from the Persea such as Persea thunbergii)

- Xiangnan pi (made from the bark of Phoebe genus trees such as Phoebe nanmu, Persea zuihoensis.

- Jigit: a resin based binder used in India

- Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

TYPES

Incense materials are available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types depending on use. Preference for one form or another varies with culture, tradition, and personal taste. Although the production of direct- and indirect-burning incense are both blended to produce a pleasant smell when burned, the two differ in their composition due to the former's requirement for even, stale, and sustained burning.

 

INDIRECT BURNING

Indirect-burning incense, also called "non-combustible incense", is a combination of aromatic ingredients that are not prepared in any particular way or encouraged into any particular form, leaving it mostly unsuitable for direct combustion. The use of this class of incense requires a separate heat source since it does not generally kindle a fire capable of burning itself and may not ignite at all under normal conditions. This incense can vary in the duration of its burning with the texture of the material. Finer ingredients tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually as they have less total surface area. The heat is traditionally provided by charcoal or glowing embers.

 

In the West, the best known incense materials of this type are frankincense and myrrh, likely due to their numerous mentions in the Christian Bible. In fact, the word for "frankincense" in many European languages also alludes to any form of incense.

 

- Whole: The incense material is burned directly in its raw unprocessed form on top of coal embers.

- Powdered or granulated: The incense material is broken down into finer bits. This incense burns quickly and provides a short period of intense smells.

- Paste: The powdered or granulated incense material is mixed with a sticky and incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type (Bakhoor actually refers to frankincense in Arabic) and Japan has a history of kneaded incense, called nerikō or awasekō, using this method.[17] Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT BURNING

Direct-burning incense also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn away the rest of the incense without continued application of heat or flame from an outside source. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types of direct-burning incense are commonly encountered, though the material itself can take virtually any form, according to expediency or whimsy:

 

- Coil: Extruded and shaped into a coil without a core. This type of incense is able to burn for an extended period, from hours to days, and is commonly produced and used by Chinese culture

- Cone: Incense in this form burns relatively fast. Incense cones were invented in Japan in the 1800s.

- Cored stick: This form of stick incense has a supporting core of bamboo. Higher quality varieties of this form have fragrant sandalwood cores. The core is coated by a thick layer of incense material that burns away with the core. This type of incense is commonly produced in India and China. When used for worship in Chinese folk religion, cored incensed sticks are sometimes known as "joss sticks".

- Solid stick: This stick incense has no supporting core and is completely made of incense material. Easily broken into pieces, it allows one to determine the specific amount of incense they wish to burn. This is the most commonly produced form of incense in Japan and Tibet.

- Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. They are typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

- Paper: Paper infused with incense, folded accordion style, lit and blown out. Examples are Carta d'Armenia and Papier d'Arménie.

- Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is highly transportable and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

The disks of powdered mugwort called 'moxa' sold in Chinese shops and herbalists are used in Traditional Chinese medicine for moxibustion treatment. Moxa tablets are not incenses; the treatment relies on heat rather than fragrance.

  

REED DIFFUSING

A reed diffuser is a form of incense that uses no heat. It comes in three parts: a bottle/container, scented essential incense oil, and bamboo reeds. The incense oil is placed into the container and bamboo reeds are then put into the same container. This is done to absorb some of the incense oil, as well as to help carry its scent and essence out of the container and into the surrounding air. Reeds typically have tiny tube openings that run the entire length of the stick. Oil is absorbed by the reed sticks and carried along the entire reed. These are do-it-yourself incense sticks that do not burn and look almost identical to typical incense sticks

 

PRODUCTION

INDIRECT BURNING

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, are then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition are made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

DIRECT BURNING

In order to obtain desired combustion qualities, attention has to be paid to certain proportions in direct burning incense mixtures:

 

- Oil content: Resinous materials such as myrrh and frankincense must not exceed the amount of dry materials in the mixture to such a degree that the incense will not smolder and burn.[citation needed] The higher the oil content relative to the dry mass, the less likely the mixture is to burn effectively.[citation needed] Typically the resinous or oily substances are balanced with "dry" materials such as wood, bark and leaf powders.

- Oxidizer quantity: The amount of chemical oxidizer in gum-bound incense must be carefully proportioned. If too little, the incense will not ignite, and if too much, the incense will burn too quickly and not produce fragrant smoke.

- Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

- Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

- Binder: Water-soluble binders such as "makko" have to be used in the right proportion to ensure that the incense mixture does not crumble when dry but also that the binder does not take up too much of the mixture.

 

Some kinds of direct-burning incense are created from "incense blanks" made of unscented combustible dust immersed into any suitable kind of essential or fragrance oil. These are often sold in America by flea-market and sidewalk vendors who have developed their own styles. Such items are often known as "dipped" or "hand-dipped" incense. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia, then simply scented with essential oils.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo cores of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. Through this process, known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and then continuously split in halves until thin sticks of bamboo with square cross sections of less than 3mm This process has been largely been replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

- Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

- Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are then evenly separated, then dipped into a tray of incense powder, consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the stick while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks that are burned in temples of Chinese folk religion produced in this fashion can have a thickness between 2 and 4 millimeters.

- Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more commonly found due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

JOSS STICKS

Joss sticks are the name given to incense sticks used for a variety of purposes associated with ritual and religious devotion in China and India. They are used in Chinese influenced East Asian and Southeast Asian countries, traditionally burned before the threshold of a home or business, before an image of a Chinese popular religion divinity or spirit of place, or in small and humble or large and elaborate shrine found at the main entrance to each and every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door, or open window as an offering to heaven, or devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

Joss-stick burning is an everyday practice in traditional Chinese religion. There are many different types of joss sticks used for different purposes or on different festive days. Many of them are long and thin and are mostly colored yellow, red, and more rarely, black. Thick joss sticks are used for special ceremonies, such as funerals. Spiral joss sticks are also used on a regular basis, which are found hanging above temple ceilings, with burn times that are exceedingly long. In some states, such as Taiwan, Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon joss sticks are sometimes used. These generate such a massive amount of smoke and heat that they are only ever burned outside.

 

Chinese incense sticks for use in popular religion are generally without aroma or only the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum.[citation needed] Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Despite the fact that they contain no sandalwood at all, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are only used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, aloeswood, or floral scents used. The Sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, Buddhism in Sri Lanka, Buddhism in Burma and Korean Buddhism do not use incense.

 

BURNING INCENSE

For indirect-burning incense, pieces of the incense are burned by placing them directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉?) is used by several Buddhist sects. The egōro is usually made of brass with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as Sonae-kō (Religious Burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. Flames on the incense are then fanned or blown out, with the incense continuing to burn without a flame on its own.

 

CULTURAL VARIATIONS

CHINESE INCENSE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life.

 

Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The poet Yu Jianwu (487-551) first recorded them: "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

 

It is incorrect to assume that the Chinese only burn incense in the home before the family shrine. In Taoist traditions, incense is inextricably associated with the 'yin' energies of the dead, temples, shrines, and ghosts. Therefore, Taoist Chinese believe burning undedicated incense in the home attracts the dreaded hungry ghosts, who consume the smoke and ruin the fortunes of the family.

 

However, since Neolithic times, the Chinese have evolved using incense not only for religious ceremonies, but also for personal and environmental aromatherapy.

 

INDIAN INCENSE

Incense stick, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, is one of the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepal/Tibet and Japanese methods of stick making which don't use a bamboo core. Though the method is also used in the west, particularly in America, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder - an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India which take raw unperfumed sticks hand-rolled by approx 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale.[38] An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 main companies who together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Bangalore.

 

In the Middle East, incense burning has been along tradition. The word bukhur means incense in Arabic. The well known choice for incense is the famous agarwood which is very popular in Africa, the Gulf and amongst some south Asians, but there are many many more choices. Incense come in a variety of forms such as blocks, pieces, pellets, granules or powdered, which is placed in the oil burner called mabkharah for several minutes to heat either with coal in the traditional way or via power in the modern way, allowing it to release its rich smell. However this takes awhile and the quick alternative is to use incense sticks called Oud in Middle East and Africa, and agarbatti in south Asia - again referring to the agar wood + batti meaning some sort of agar-stick. Occasionally some get confused between bukhur and oud, bukhur is the insence ie agarwood, sandlewood etc and oud being the incense sticks (and not the otherway round sometimes wires get twisted)

 

JERUSALEM TEMPLE INCENSE

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus as a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN INCENSE

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, or sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE INCENSE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like Calligraphy, Ikebana, and Scroll Arrangement. However the art of incense appreciation or Koh-do, is generally practiced as a separate art form from the tea ceremony, however usually practiced within a tea room of traditional Zen design.

 

Agarwood (沈香　Jinkō) and sandalwood (白檀　Byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "Jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation.[citation needed] It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

- Incense Arts: [香道, Kodo]

- Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

- Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

- Charcoal: [木炭] – only the odorless kind is used.

- Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

Incense is used for a variety of purposes, including the ceremonies of all the main religions, to overcome bad smells, repel insects, purify or improve the atmosphere, aromatherapy, meditation, and for simple pleasure.

 

PRACTICAL

Incense fragrances can be of such great strength that they obscure other, less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. Another example of this use, as well as of religious use, is the giant Botafumeiro thurible which swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single, long handle on one side. It is important to note that the perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct combustion incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve and captivate several of the senses.

 

Incense made from materials such as citronella can repel mosquitoes and other aggravating, distracting or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors, and do not want the scent to linger.

 

AestheticMany people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the refined sensory experience. This use is perhaps best exemplified in the kōdō (香道?), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.ReligiousUse of incense in religion is prevalent in many cultures and may have their roots in the practical and aesthetic uses considering that many religions with not much else in common all use incense. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense [to ancestors/gods]), etc.

 

HEALTH

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and absorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. The emission rate decreases in the row Indian sandalwood > Japanese aloeswood > Taiwanese aloeswood > smokeless sandalwood.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, a study by several Asian Cancer Research Centers showed: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified the findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and cancer of the lung, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also had higher rates of a type of cancer called squamous-cell carcinoma, which refers to tumors that arise in the cells lining the internal and external surfaces of the body. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters ovary cells to be even higher than cigarettes.

 

Frankincense has been shown to cause antidepressive behavior in mice. It activated the poorly understood ion channels in the brain to alleviate anxiety and depression.

 

WIKIPEDIA

Incense is aromatic biotic material which releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for a variety of purposes, including the ceremonies of religion, to overcome bad smells, repel insects, spirituality, aromatherapy, meditation, and for simple pleasure.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing diversity in the reasons for burning it. Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin for incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense within both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, furnishing tangible archaeological substantiation to the prominence of incense and related compounds within Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300 BCE- 1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the inherited formulation to encompass aromatic roots and other indigenous flora. This comprised the initial usage of subterranean plant parts within the fabrication of incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians for incense.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented instance of incense utilization comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, sandalwood, amongst others) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song Dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th century Shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whomever might take his head in battle). It wasn't until the Muromachi Era during the 15th and 16th century that incense appreciation (Kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

The same could be said for the techniques used to make incense. Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, among them clergy and physicians who were both familiar with incense arts.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

- Fuel and oxidizer mixtures: Charcoal or wood powder forms the fuel for the combustion. Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are combined into the base prior to formation as in the case of powdered incense materials or after formation as in the case of essential oils. The formula for the charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

- Natural plant-based binders: Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. This includes:

- Makko (incense powder): made from the bark of various trees from the Persea such as Persea thunbergii)

- Xiangnan pi (made from the bark of Phoebe genus trees such as Phoebe nanmu, Persea zuihoensis.

- Jigit: a resin based binder used in India

- Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

TYPES

Incense materials are available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types depending on use. Preference for one form or another varies with culture, tradition, and personal taste. Although the production of direct- and indirect-burning incense are both blended to produce a pleasant smell when burned, the two differ in their composition due to the former's requirement for even, stale, and sustained burning.

 

INDIRECT BURNING

Indirect-burning incense, also called "non-combustible incense", is a combination of aromatic ingredients that are not prepared in any particular way or encouraged into any particular form, leaving it mostly unsuitable for direct combustion. The use of this class of incense requires a separate heat source since it does not generally kindle a fire capable of burning itself and may not ignite at all under normal conditions. This incense can vary in the duration of its burning with the texture of the material. Finer ingredients tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually as they have less total surface area. The heat is traditionally provided by charcoal or glowing embers.

 

In the West, the best known incense materials of this type are frankincense and myrrh, likely due to their numerous mentions in the Christian Bible. In fact, the word for "frankincense" in many European languages also alludes to any form of incense.

 

- Whole: The incense material is burned directly in its raw unprocessed form on top of coal embers.

- Powdered or granulated: The incense material is broken down into finer bits. This incense burns quickly and provides a short period of intense smells.

- Paste: The powdered or granulated incense material is mixed with a sticky and incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type (Bakhoor actually refers to frankincense in Arabic) and Japan has a history of kneaded incense, called nerikō or awasekō, using this method.[17] Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT BURNING

Direct-burning incense also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn away the rest of the incense without continued application of heat or flame from an outside source. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types of direct-burning incense are commonly encountered, though the material itself can take virtually any form, according to expediency or whimsy:

 

- Coil: Extruded and shaped into a coil without a core. This type of incense is able to burn for an extended period, from hours to days, and is commonly produced and used by Chinese culture

- Cone: Incense in this form burns relatively fast. Incense cones were invented in Japan in the 1800s.

- Cored stick: This form of stick incense has a supporting core of bamboo. Higher quality varieties of this form have fragrant sandalwood cores. The core is coated by a thick layer of incense material that burns away with the core. This type of incense is commonly produced in India and China. When used for worship in Chinese folk religion, cored incensed sticks are sometimes known as "joss sticks".

- Solid stick: This stick incense has no supporting core and is completely made of incense material. Easily broken into pieces, it allows one to determine the specific amount of incense they wish to burn. This is the most commonly produced form of incense in Japan and Tibet.

- Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. They are typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

- Paper: Paper infused with incense, folded accordion style, lit and blown out. Examples are Carta d'Armenia and Papier d'Arménie.

- Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is highly transportable and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

The disks of powdered mugwort called 'moxa' sold in Chinese shops and herbalists are used in Traditional Chinese medicine for moxibustion treatment. Moxa tablets are not incenses; the treatment relies on heat rather than fragrance.

  

REED DIFFUSING

A reed diffuser is a form of incense that uses no heat. It comes in three parts: a bottle/container, scented essential incense oil, and bamboo reeds. The incense oil is placed into the container and bamboo reeds are then put into the same container. This is done to absorb some of the incense oil, as well as to help carry its scent and essence out of the container and into the surrounding air. Reeds typically have tiny tube openings that run the entire length of the stick. Oil is absorbed by the reed sticks and carried along the entire reed. These are do-it-yourself incense sticks that do not burn and look almost identical to typical incense sticks

 

PRODUCTION

INDIRECT BURNING

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, are then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition are made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

DIRECT BURNING

In order to obtain desired combustion qualities, attention has to be paid to certain proportions in direct burning incense mixtures:

 

- Oil content: Resinous materials such as myrrh and frankincense must not exceed the amount of dry materials in the mixture to such a degree that the incense will not smolder and burn.[citation needed] The higher the oil content relative to the dry mass, the less likely the mixture is to burn effectively.[citation needed] Typically the resinous or oily substances are balanced with "dry" materials such as wood, bark and leaf powders.

- Oxidizer quantity: The amount of chemical oxidizer in gum-bound incense must be carefully proportioned. If too little, the incense will not ignite, and if too much, the incense will burn too quickly and not produce fragrant smoke.

- Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

- Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

- Binder: Water-soluble binders such as "makko" have to be used in the right proportion to ensure that the incense mixture does not crumble when dry but also that the binder does not take up too much of the mixture.

 

Some kinds of direct-burning incense are created from "incense blanks" made of unscented combustible dust immersed into any suitable kind of essential or fragrance oil. These are often sold in America by flea-market and sidewalk vendors who have developed their own styles. Such items are often known as "dipped" or "hand-dipped" incense. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia, then simply scented with essential oils.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo cores of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. Through this process, known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and then continuously split in halves until thin sticks of bamboo with square cross sections of less than 3mm This process has been largely been replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

- Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

- Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are then evenly separated, then dipped into a tray of incense powder, consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the stick while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks that are burned in temples of Chinese folk religion produced in this fashion can have a thickness between 2 and 4 millimeters.

- Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more commonly found due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

JOSS STICKS

Joss sticks are the name given to incense sticks used for a variety of purposes associated with ritual and religious devotion in China and India. They are used in Chinese influenced East Asian and Southeast Asian countries, traditionally burned before the threshold of a home or business, before an image of a Chinese popular religion divinity or spirit of place, or in small and humble or large and elaborate shrine found at the main entrance to each and every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door, or open window as an offering to heaven, or devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

Joss-stick burning is an everyday practice in traditional Chinese religion. There are many different types of joss sticks used for different purposes or on different festive days. Many of them are long and thin and are mostly colored yellow, red, and more rarely, black. Thick joss sticks are used for special ceremonies, such as funerals. Spiral joss sticks are also used on a regular basis, which are found hanging above temple ceilings, with burn times that are exceedingly long. In some states, such as Taiwan, Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon joss sticks are sometimes used. These generate such a massive amount of smoke and heat that they are only ever burned outside.

 

Chinese incense sticks for use in popular religion are generally without aroma or only the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum.[citation needed] Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Despite the fact that they contain no sandalwood at all, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are only used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, aloeswood, or floral scents used. The Sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, Buddhism in Sri Lanka, Buddhism in Burma and Korean Buddhism do not use incense.

 

BURNING INCENSE

For indirect-burning incense, pieces of the incense are burned by placing them directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉?) is used by several Buddhist sects. The egōro is usually made of brass with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as Sonae-kō (Religious Burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. Flames on the incense are then fanned or blown out, with the incense continuing to burn without a flame on its own.

 

CULTURAL VARIATIONS

CHINESE INCENSE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life.

 

Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The poet Yu Jianwu (487-551) first recorded them: "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

 

It is incorrect to assume that the Chinese only burn incense in the home before the family shrine. In Taoist traditions, incense is inextricably associated with the 'yin' energies of the dead, temples, shrines, and ghosts. Therefore, Taoist Chinese believe burning undedicated incense in the home attracts the dreaded hungry ghosts, who consume the smoke and ruin the fortunes of the family.

 

However, since Neolithic times, the Chinese have evolved using incense not only for religious ceremonies, but also for personal and environmental aromatherapy.

 

INDIAN INCENSE

Incense stick, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, is one of the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepal/Tibet and Japanese methods of stick making which don't use a bamboo core. Though the method is also used in the west, particularly in America, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder - an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India which take raw unperfumed sticks hand-rolled by approx 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale.[38] An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 main companies who together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Bangalore.

 

In the Middle East, incense burning has been along tradition. The word bukhur means incense in Arabic. The well known choice for incense is the famous agarwood which is very popular in Africa, the Gulf and amongst some south Asians, but there are many many more choices. Incense come in a variety of forms such as blocks, pieces, pellets, granules or powdered, which is placed in the oil burner called mabkharah for several minutes to heat either with coal in the traditional way or via power in the modern way, allowing it to release its rich smell. However this takes awhile and the quick alternative is to use incense sticks called Oud in Middle East and Africa, and agarbatti in south Asia - again referring to the agar wood + batti meaning some sort of agar-stick. Occasionally some get confused between bukhur and oud, bukhur is the insence ie agarwood, sandlewood etc and oud being the incense sticks (and not the otherway round sometimes wires get twisted)

 

JERUSALEM TEMPLE INCENSE

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus as a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN INCENSE

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, or sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE INCENSE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like Calligraphy, Ikebana, and Scroll Arrangement. However the art of incense appreciation or Koh-do, is generally practiced as a separate art form from the tea ceremony, however usually practiced within a tea room of traditional Zen design.

 

Agarwood (沈香　Jinkō) and sandalwood (白檀　Byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "Jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation.[citation needed] It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

- Incense Arts: [香道, Kodo]

- Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

- Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

- Charcoal: [木炭] – only the odorless kind is used.

- Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

Incense is used for a variety of purposes, including the ceremonies of all the main religions, to overcome bad smells, repel insects, purify or improve the atmosphere, aromatherapy, meditation, and for simple pleasure.

 

PRACTICAL

Incense fragrances can be of such great strength that they obscure other, less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. Another example of this use, as well as of religious use, is the giant Botafumeiro thurible which swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single, long handle on one side. It is important to note that the perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct combustion incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve and captivate several of the senses.

 

Incense made from materials such as citronella can repel mosquitoes and other aggravating, distracting or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors, and do not want the scent to linger.

 

AestheticMany people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the refined sensory experience. This use is perhaps best exemplified in the kōdō (香道?), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.ReligiousUse of incense in religion is prevalent in many cultures and may have their roots in the practical and aesthetic uses considering that many religions with not much else in common all use incense. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense [to ancestors/gods]), etc.

 

HEALTH

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and absorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. The emission rate decreases in the row Indian sandalwood > Japanese aloeswood > Taiwanese aloeswood > smokeless sandalwood.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, a study by several Asian Cancer Research Centers showed: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified the findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and cancer of the lung, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also had higher rates of a type of cancer called squamous-cell carcinoma, which refers to tumors that arise in the cells lining the internal and external surfaces of the body. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters ovary cells to be even higher than cigarettes.

 

Frankincense has been shown to cause antidepressive behavior in mice. It activated the poorly understood ion channels in the brain to alleviate anxiety and depression.

 

WIKIPEDIA

Incense is aromatic biotic material which releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for a variety of purposes, including the ceremonies of religion, to overcome bad smells, repel insects, spirituality, aromatherapy, meditation, and for simple pleasure.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing diversity in the reasons for burning it. Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin for incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense within both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, furnishing tangible archaeological substantiation to the prominence of incense and related compounds within Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300 BCE- 1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the inherited formulation to encompass aromatic roots and other indigenous flora. This comprised the initial usage of subterranean plant parts within the fabrication of incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians for incense.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented instance of incense utilization comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, sandalwood, amongst others) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song Dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th century Shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whomever might take his head in battle). It wasn't until the Muromachi Era during the 15th and 16th century that incense appreciation (Kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

The same could be said for the techniques used to make incense. Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, among them clergy and physicians who were both familiar with incense arts.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

- Fuel and oxidizer mixtures: Charcoal or wood powder forms the fuel for the combustion. Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are combined into the base prior to formation as in the case of powdered incense materials or after formation as in the case of essential oils. The formula for the charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

- Natural plant-based binders: Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. This includes:

- Makko (incense powder): made from the bark of various trees from the Persea such as Persea thunbergii)

- Xiangnan pi (made from the bark of Phoebe genus trees such as Phoebe nanmu, Persea zuihoensis.

- Jigit: a resin based binder used in India

- Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

TYPES

Incense materials are available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types depending on use. Preference for one form or another varies with culture, tradition, and personal taste. Although the production of direct- and indirect-burning incense are both blended to produce a pleasant smell when burned, the two differ in their composition due to the former's requirement for even, stale, and sustained burning.

 

INDIRECT BURNING

Indirect-burning incense, also called "non-combustible incense", is a combination of aromatic ingredients that are not prepared in any particular way or encouraged into any particular form, leaving it mostly unsuitable for direct combustion. The use of this class of incense requires a separate heat source since it does not generally kindle a fire capable of burning itself and may not ignite at all under normal conditions. This incense can vary in the duration of its burning with the texture of the material. Finer ingredients tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually as they have less total surface area. The heat is traditionally provided by charcoal or glowing embers.

 

In the West, the best known incense materials of this type are frankincense and myrrh, likely due to their numerous mentions in the Christian Bible. In fact, the word for "frankincense" in many European languages also alludes to any form of incense.

 

- Whole: The incense material is burned directly in its raw unprocessed form on top of coal embers.

- Powdered or granulated: The incense material is broken down into finer bits. This incense burns quickly and provides a short period of intense smells.

- Paste: The powdered or granulated incense material is mixed with a sticky and incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type (Bakhoor actually refers to frankincense in Arabic) and Japan has a history of kneaded incense, called nerikō or awasekō, using this method.[17] Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT BURNING

Direct-burning incense also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn away the rest of the incense without continued application of heat or flame from an outside source. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types of direct-burning incense are commonly encountered, though the material itself can take virtually any form, according to expediency or whimsy:

 

- Coil: Extruded and shaped into a coil without a core. This type of incense is able to burn for an extended period, from hours to days, and is commonly produced and used by Chinese culture

- Cone: Incense in this form burns relatively fast. Incense cones were invented in Japan in the 1800s.

- Cored stick: This form of stick incense has a supporting core of bamboo. Higher quality varieties of this form have fragrant sandalwood cores. The core is coated by a thick layer of incense material that burns away with the core. This type of incense is commonly produced in India and China. When used for worship in Chinese folk religion, cored incensed sticks are sometimes known as "joss sticks".

- Solid stick: This stick incense has no supporting core and is completely made of incense material. Easily broken into pieces, it allows one to determine the specific amount of incense they wish to burn. This is the most commonly produced form of incense in Japan and Tibet.

- Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. They are typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

- Paper: Paper infused with incense, folded accordion style, lit and blown out. Examples are Carta d'Armenia and Papier d'Arménie.

- Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is highly transportable and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

The disks of powdered mugwort called 'moxa' sold in Chinese shops and herbalists are used in Traditional Chinese medicine for moxibustion treatment. Moxa tablets are not incenses; the treatment relies on heat rather than fragrance.

  

REED DIFFUSING

A reed diffuser is a form of incense that uses no heat. It comes in three parts: a bottle/container, scented essential incense oil, and bamboo reeds. The incense oil is placed into the container and bamboo reeds are then put into the same container. This is done to absorb some of the incense oil, as well as to help carry its scent and essence out of the container and into the surrounding air. Reeds typically have tiny tube openings that run the entire length of the stick. Oil is absorbed by the reed sticks and carried along the entire reed. These are do-it-yourself incense sticks that do not burn and look almost identical to typical incense sticks

 

PRODUCTION

INDIRECT BURNING

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, are then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition are made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

DIRECT BURNING

In order to obtain desired combustion qualities, attention has to be paid to certain proportions in direct burning incense mixtures:

 

- Oil content: Resinous materials such as myrrh and frankincense must not exceed the amount of dry materials in the mixture to such a degree that the incense will not smolder and burn.[citation needed] The higher the oil content relative to the dry mass, the less likely the mixture is to burn effectively.[citation needed] Typically the resinous or oily substances are balanced with "dry" materials such as wood, bark and leaf powders.

- Oxidizer quantity: The amount of chemical oxidizer in gum-bound incense must be carefully proportioned. If too little, the incense will not ignite, and if too much, the incense will burn too quickly and not produce fragrant smoke.

- Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

- Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

- Binder: Water-soluble binders such as "makko" have to be used in the right proportion to ensure that the incense mixture does not crumble when dry but also that the binder does not take up too much of the mixture.

 

Some kinds of direct-burning incense are created from "incense blanks" made of unscented combustible dust immersed into any suitable kind of essential or fragrance oil. These are often sold in America by flea-market and sidewalk vendors who have developed their own styles. Such items are often known as "dipped" or "hand-dipped" incense. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia, then simply scented with essential oils.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo cores of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. Through this process, known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and then continuously split in halves until thin sticks of bamboo with square cross sections of less than 3mm This process has been largely been replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

- Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

- Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are then evenly separated, then dipped into a tray of incense powder, consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the stick while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks that are burned in temples of Chinese folk religion produced in this fashion can have a thickness between 2 and 4 millimeters.

- Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more commonly found due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

JOSS STICKS

Joss sticks are the name given to incense sticks used for a variety of purposes associated with ritual and religious devotion in China and India. They are used in Chinese influenced East Asian and Southeast Asian countries, traditionally burned before the threshold of a home or business, before an image of a Chinese popular religion divinity or spirit of place, or in small and humble or large and elaborate shrine found at the main entrance to each and every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door, or open window as an offering to heaven, or devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

Joss-stick burning is an everyday practice in traditional Chinese religion. There are many different types of joss sticks used for different purposes or on different festive days. Many of them are long and thin and are mostly colored yellow, red, and more rarely, black. Thick joss sticks are used for special ceremonies, such as funerals. Spiral joss sticks are also used on a regular basis, which are found hanging above temple ceilings, with burn times that are exceedingly long. In some states, such as Taiwan, Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon joss sticks are sometimes used. These generate such a massive amount of smoke and heat that they are only ever burned outside.

 

Chinese incense sticks for use in popular religion are generally without aroma or only the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum.[citation needed] Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Despite the fact that they contain no sandalwood at all, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are only used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, aloeswood, or floral scents used. The Sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, Buddhism in Sri Lanka, Buddhism in Burma and Korean Buddhism do not use incense.

 

BURNING INCENSE

For indirect-burning incense, pieces of the incense are burned by placing them directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉?) is used by several Buddhist sects. The egōro is usually made of brass with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as Sonae-kō (Religious Burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. Flames on the incense are then fanned or blown out, with the incense continuing to burn without a flame on its own.

 

CULTURAL VARIATIONS

CHINESE INCENSE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life.

 

Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The poet Yu Jianwu (487-551) first recorded them: "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

 

It is incorrect to assume that the Chinese only burn incense in the home before the family shrine. In Taoist traditions, incense is inextricably associated with the 'yin' energies of the dead, temples, shrines, and ghosts. Therefore, Taoist Chinese believe burning undedicated incense in the home attracts the dreaded hungry ghosts, who consume the smoke and ruin the fortunes of the family.

 

However, since Neolithic times, the Chinese have evolved using incense not only for religious ceremonies, but also for personal and environmental aromatherapy.

 

INDIAN INCENSE

Incense stick, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, is one of the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepal/Tibet and Japanese methods of stick making which don't use a bamboo core. Though the method is also used in the west, particularly in America, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder - an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India which take raw unperfumed sticks hand-rolled by approx 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale.[38] An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 main companies who together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Bangalore.

 

In the Middle East, incense burning has been along tradition. The word bukhur means incense in Arabic. The well known choice for incense is the famous agarwood which is very popular in Africa, the Gulf and amongst some south Asians, but there are many many more choices. Incense come in a variety of forms such as blocks, pieces, pellets, granules or powdered, which is placed in the oil burner called mabkharah for several minutes to heat either with coal in the traditional way or via power in the modern way, allowing it to release its rich smell. However this takes awhile and the quick alternative is to use incense sticks called Oud in Middle East and Africa, and agarbatti in south Asia - again referring to the agar wood + batti meaning some sort of agar-stick. Occasionally some get confused between bukhur and oud, bukhur is the insence ie agarwood, sandlewood etc and oud being the incense sticks (and not the otherway round sometimes wires get twisted)

 

JERUSALEM TEMPLE INCENSE

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus as a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN INCENSE

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, or sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE INCENSE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like Calligraphy, Ikebana, and Scroll Arrangement. However the art of incense appreciation or Koh-do, is generally practiced as a separate art form from the tea ceremony, however usually practiced within a tea room of traditional Zen design.

 

Agarwood (沈香　Jinkō) and sandalwood (白檀　Byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "Jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation.[citation needed] It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

- Incense Arts: [香道, Kodo]

- Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

- Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

- Charcoal: [木炭] – only the odorless kind is used.

- Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

Incense is used for a variety of purposes, including the ceremonies of all the main religions, to overcome bad smells, repel insects, purify or improve the atmosphere, aromatherapy, meditation, and for simple pleasure.

 

PRACTICAL

Incense fragrances can be of such great strength that they obscure other, less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. Another example of this use, as well as of religious use, is the giant Botafumeiro thurible which swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single, long handle on one side. It is important to note that the perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct combustion incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve and captivate several of the senses.

 

Incense made from materials such as citronella can repel mosquitoes and other aggravating, distracting or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors, and do not want the scent to linger.

 

AestheticMany people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the refined sensory experience. This use is perhaps best exemplified in the kōdō (香道?), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.ReligiousUse of incense in religion is prevalent in many cultures and may have their roots in the practical and aesthetic uses considering that many religions with not much else in common all use incense. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense [to ancestors/gods]), etc.

 

HEALTH

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and absorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. The emission rate decreases in the row Indian sandalwood > Japanese aloeswood > Taiwanese aloeswood > smokeless sandalwood.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, a study by several Asian Cancer Research Centers showed: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified the findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and cancer of the lung, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also had higher rates of a type of cancer called squamous-cell carcinoma, which refers to tumors that arise in the cells lining the internal and external surfaces of the body. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters ovary cells to be even higher than cigarettes.

 

Frankincense has been shown to cause antidepressive behavior in mice. It activated the poorly understood ion channels in the brain to alleviate anxiety and depression.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material which releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for a variety of purposes, including the ceremonies of religion, to overcome bad smells, repel insects, spirituality, aromatherapy, meditation, and for simple pleasure.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing diversity in the reasons for burning it. Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin for incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense within both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, furnishing tangible archaeological substantiation to the prominence of incense and related compounds within Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300 BCE- 1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the inherited formulation to encompass aromatic roots and other indigenous flora. This comprised the initial usage of subterranean plant parts within the fabrication of incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians for incense.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented instance of incense utilization comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, sandalwood, amongst others) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song Dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th century Shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whomever might take his head in battle). It wasn't until the Muromachi Era during the 15th and 16th century that incense appreciation (Kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

The same could be said for the techniques used to make incense. Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, among them clergy and physicians who were both familiar with incense arts.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

- Fuel and oxidizer mixtures: Charcoal or wood powder forms the fuel for the combustion. Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are combined into the base prior to formation as in the case of powdered incense materials or after formation as in the case of essential oils. The formula for the charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

- Natural plant-based binders: Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. This includes:

- Makko (incense powder): made from the bark of various trees from the Persea such as Persea thunbergii)

- Xiangnan pi (made from the bark of Phoebe genus trees such as Phoebe nanmu, Persea zuihoensis.

- Jigit: a resin based binder used in India

- Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

TYPES

Incense materials are available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types depending on use. Preference for one form or another varies with culture, tradition, and personal taste. Although the production of direct- and indirect-burning incense are both blended to produce a pleasant smell when burned, the two differ in their composition due to the former's requirement for even, stale, and sustained burning.

 

INDIRECT BURNING

Indirect-burning incense, also called "non-combustible incense", is a combination of aromatic ingredients that are not prepared in any particular way or encouraged into any particular form, leaving it mostly unsuitable for direct combustion. The use of this class of incense requires a separate heat source since it does not generally kindle a fire capable of burning itself and may not ignite at all under normal conditions. This incense can vary in the duration of its burning with the texture of the material. Finer ingredients tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually as they have less total surface area. The heat is traditionally provided by charcoal or glowing embers.

 

In the West, the best known incense materials of this type are frankincense and myrrh, likely due to their numerous mentions in the Christian Bible. In fact, the word for "frankincense" in many European languages also alludes to any form of incense.

 

- Whole: The incense material is burned directly in its raw unprocessed form on top of coal embers.

- Powdered or granulated: The incense material is broken down into finer bits. This incense burns quickly and provides a short period of intense smells.

- Paste: The powdered or granulated incense material is mixed with a sticky and incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type (Bakhoor actually refers to frankincense in Arabic) and Japan has a history of kneaded incense, called nerikō or awasekō, using this method.[17] Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT BURNING

Direct-burning incense also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn away the rest of the incense without continued application of heat or flame from an outside source. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types of direct-burning incense are commonly encountered, though the material itself can take virtually any form, according to expediency or whimsy:

 

- Coil: Extruded and shaped into a coil without a core. This type of incense is able to burn for an extended period, from hours to days, and is commonly produced and used by Chinese culture

- Cone: Incense in this form burns relatively fast. Incense cones were invented in Japan in the 1800s.

- Cored stick: This form of stick incense has a supporting core of bamboo. Higher quality varieties of this form have fragrant sandalwood cores. The core is coated by a thick layer of incense material that burns away with the core. This type of incense is commonly produced in India and China. When used for worship in Chinese folk religion, cored incensed sticks are sometimes known as "joss sticks".

- Solid stick: This stick incense has no supporting core and is completely made of incense material. Easily broken into pieces, it allows one to determine the specific amount of incense they wish to burn. This is the most commonly produced form of incense in Japan and Tibet.

- Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. They are typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

- Paper: Paper infused with incense, folded accordion style, lit and blown out. Examples are Carta d'Armenia and Papier d'Arménie.

- Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is highly transportable and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

The disks of powdered mugwort called 'moxa' sold in Chinese shops and herbalists are used in Traditional Chinese medicine for moxibustion treatment. Moxa tablets are not incenses; the treatment relies on heat rather than fragrance.

  

REED DIFFUSING

A reed diffuser is a form of incense that uses no heat. It comes in three parts: a bottle/container, scented essential incense oil, and bamboo reeds. The incense oil is placed into the container and bamboo reeds are then put into the same container. This is done to absorb some of the incense oil, as well as to help carry its scent and essence out of the container and into the surrounding air. Reeds typically have tiny tube openings that run the entire length of the stick. Oil is absorbed by the reed sticks and carried along the entire reed. These are do-it-yourself incense sticks that do not burn and look almost identical to typical incense sticks

 

PRODUCTION

INDIRECT BURNING

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, are then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition are made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

DIRECT BURNING

In order to obtain desired combustion qualities, attention has to be paid to certain proportions in direct burning incense mixtures:

 

- Oil content: Resinous materials such as myrrh and frankincense must not exceed the amount of dry materials in the mixture to such a degree that the incense will not smolder and burn.[citation needed] The higher the oil content relative to the dry mass, the less likely the mixture is to burn effectively.[citation needed] Typically the resinous or oily substances are balanced with "dry" materials such as wood, bark and leaf powders.

- Oxidizer quantity: The amount of chemical oxidizer in gum-bound incense must be carefully proportioned. If too little, the incense will not ignite, and if too much, the incense will burn too quickly and not produce fragrant smoke.

- Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

- Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

- Binder: Water-soluble binders such as "makko" have to be used in the right proportion to ensure that the incense mixture does not crumble when dry but also that the binder does not take up too much of the mixture.

 

Some kinds of direct-burning incense are created from "incense blanks" made of unscented combustible dust immersed into any suitable kind of essential or fragrance oil. These are often sold in America by flea-market and sidewalk vendors who have developed their own styles. Such items are often known as "dipped" or "hand-dipped" incense. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia, then simply scented with essential oils.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo cores of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. Through this process, known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and then continuously split in halves until thin sticks of bamboo with square cross sections of less than 3mm This process has been largely been replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

- Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

- Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are then evenly separated, then dipped into a tray of incense powder, consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the stick while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks that are burned in temples of Chinese folk religion produced in this fashion can have a thickness between 2 and 4 millimeters.

- Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more commonly found due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

JOSS STICKS

Joss sticks are the name given to incense sticks used for a variety of purposes associated with ritual and religious devotion in China and India. They are used in Chinese influenced East Asian and Southeast Asian countries, traditionally burned before the threshold of a home or business, before an image of a Chinese popular religion divinity or spirit of place, or in small and humble or large and elaborate shrine found at the main entrance to each and every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door, or open window as an offering to heaven, or devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

Joss-stick burning is an everyday practice in traditional Chinese religion. There are many different types of joss sticks used for different purposes or on different festive days. Many of them are long and thin and are mostly colored yellow, red, and more rarely, black. Thick joss sticks are used for special ceremonies, such as funerals. Spiral joss sticks are also used on a regular basis, which are found hanging above temple ceilings, with burn times that are exceedingly long. In some states, such as Taiwan, Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon joss sticks are sometimes used. These generate such a massive amount of smoke and heat that they are only ever burned outside.

 

Chinese incense sticks for use in popular religion are generally without aroma or only the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum.[citation needed] Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Despite the fact that they contain no sandalwood at all, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are only used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, aloeswood, or floral scents used. The Sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, Buddhism in Sri Lanka, Buddhism in Burma and Korean Buddhism do not use incense.

 

BURNING INCENSE

For indirect-burning incense, pieces of the incense are burned by placing them directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉?) is used by several Buddhist sects. The egōro is usually made of brass with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as Sonae-kō (Religious Burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. Flames on the incense are then fanned or blown out, with the incense continuing to burn without a flame on its own.

 

CULTURAL VARIATIONS

CHINESE INCENSE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life.

 

Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The poet Yu Jianwu (487-551) first recorded them: "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

 

It is incorrect to assume that the Chinese only burn incense in the home before the family shrine. In Taoist traditions, incense is inextricably associated with the 'yin' energies of the dead, temples, shrines, and ghosts. Therefore, Taoist Chinese believe burning undedicated incense in the home attracts the dreaded hungry ghosts, who consume the smoke and ruin the fortunes of the family.

 

However, since Neolithic times, the Chinese have evolved using incense not only for religious ceremonies, but also for personal and environmental aromatherapy.

 

INDIAN INCENSE

Incense stick, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, is one of the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepal/Tibet and Japanese methods of stick making which don't use a bamboo core. Though the method is also used in the west, particularly in America, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder - an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India which take raw unperfumed sticks hand-rolled by approx 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale.[38] An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 main companies who together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Bangalore.

 

In the Middle East, incense burning has been along tradition. The word bukhur means incense in Arabic. The well known choice for incense is the famous agarwood which is very popular in Africa, the Gulf and amongst some south Asians, but there are many many more choices. Incense come in a variety of forms such as blocks, pieces, pellets, granules or powdered, which is placed in the oil burner called mabkharah for several minutes to heat either with coal in the traditional way or via power in the modern way, allowing it to release its rich smell. However this takes awhile and the quick alternative is to use incense sticks called Oud in Middle East and Africa, and agarbatti in south Asia - again referring to the agar wood + batti meaning some sort of agar-stick. Occasionally some get confused between bukhur and oud, bukhur is the insence ie agarwood, sandlewood etc and oud being the incense sticks (and not the otherway round sometimes wires get twisted)

 

JERUSALEM TEMPLE INCENSE

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus as a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN INCENSE

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, or sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE INCENSE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like Calligraphy, Ikebana, and Scroll Arrangement. However the art of incense appreciation or Koh-do, is generally practiced as a separate art form from the tea ceremony, however usually practiced within a tea room of traditional Zen design.

 

Agarwood (沈香　Jinkō) and sandalwood (白檀　Byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "Jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation.[citation needed] It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

- Incense Arts: [香道, Kodo]

- Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

- Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

- Charcoal: [木炭] – only the odorless kind is used.

- Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

Incense is used for a variety of purposes, including the ceremonies of all the main religions, to overcome bad smells, repel insects, purify or improve the atmosphere, aromatherapy, meditation, and for simple pleasure.

 

PRACTICAL

Incense fragrances can be of such great strength that they obscure other, less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. Another example of this use, as well as of religious use, is the giant Botafumeiro thurible which swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single, long handle on one side. It is important to note that the perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct combustion incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve and captivate several of the senses.

 

Incense made from materials such as citronella can repel mosquitoes and other aggravating, distracting or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors, and do not want the scent to linger.

 

AestheticMany people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the refined sensory experience. This use is perhaps best exemplified in the kōdō (香道?), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.ReligiousUse of incense in religion is prevalent in many cultures and may have their roots in the practical and aesthetic uses considering that many religions with not much else in common all use incense. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense [to ancestors/gods]), etc.

 

HEALTH

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and absorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. The emission rate decreases in the row Indian sandalwood > Japanese aloeswood > Taiwanese aloeswood > smokeless sandalwood.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, a study by several Asian Cancer Research Centers showed: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified the findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and cancer of the lung, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also had higher rates of a type of cancer called squamous-cell carcinoma, which refers to tumors that arise in the cells lining the internal and external surfaces of the body. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters ovary cells to be even higher than cigarettes.

 

Frankincense has been shown to cause antidepressive behavior in mice. It activated the poorly understood ion channels in the brain to alleviate anxiety and depression.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material which releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for a variety of purposes, including the ceremonies of religion, to overcome bad smells, repel insects, spirituality, aromatherapy, meditation, and for simple pleasure.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing diversity in the reasons for burning it. Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin for incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense within both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, furnishing tangible archaeological substantiation to the prominence of incense and related compounds within Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300 BCE- 1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the inherited formulation to encompass aromatic roots and other indigenous flora. This comprised the initial usage of subterranean plant parts within the fabrication of incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians for incense.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented instance of incense utilization comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, sandalwood, amongst others) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song Dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th century Shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whomever might take his head in battle). It wasn't until the Muromachi Era during the 15th and 16th century that incense appreciation (Kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

The same could be said for the techniques used to make incense. Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, among them clergy and physicians who were both familiar with incense arts.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

- Fuel and oxidizer mixtures: Charcoal or wood powder forms the fuel for the combustion. Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are combined into the base prior to formation as in the case of powdered incense materials or after formation as in the case of essential oils. The formula for the charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

- Natural plant-based binders: Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. This includes:

- Makko (incense powder): made from the bark of various trees from the Persea such as Persea thunbergii)

- Xiangnan pi (made from the bark of Phoebe genus trees such as Phoebe nanmu, Persea zuihoensis.

- Jigit: a resin based binder used in India

- Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

TYPES

Incense materials are available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types depending on use. Preference for one form or another varies with culture, tradition, and personal taste. Although the production of direct- and indirect-burning incense are both blended to produce a pleasant smell when burned, the two differ in their composition due to the former's requirement for even, stale, and sustained burning.

 

INDIRECT BURNING

Indirect-burning incense, also called "non-combustible incense", is a combination of aromatic ingredients that are not prepared in any particular way or encouraged into any particular form, leaving it mostly unsuitable for direct combustion. The use of this class of incense requires a separate heat source since it does not generally kindle a fire capable of burning itself and may not ignite at all under normal conditions. This incense can vary in the duration of its burning with the texture of the material. Finer ingredients tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually as they have less total surface area. The heat is traditionally provided by charcoal or glowing embers.

 

In the West, the best known incense materials of this type are frankincense and myrrh, likely due to their numerous mentions in the Christian Bible. In fact, the word for "frankincense" in many European languages also alludes to any form of incense.

 

- Whole: The incense material is burned directly in its raw unprocessed form on top of coal embers.

- Powdered or granulated: The incense material is broken down into finer bits. This incense burns quickly and provides a short period of intense smells.

- Paste: The powdered or granulated incense material is mixed with a sticky and incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type (Bakhoor actually refers to frankincense in Arabic) and Japan has a history of kneaded incense, called nerikō or awasekō, using this method.[17] Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT BURNING

Direct-burning incense also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn away the rest of the incense without continued application of heat or flame from an outside source. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types of direct-burning incense are commonly encountered, though the material itself can take virtually any form, according to expediency or whimsy:

 

- Coil: Extruded and shaped into a coil without a core. This type of incense is able to burn for an extended period, from hours to days, and is commonly produced and used by Chinese culture

- Cone: Incense in this form burns relatively fast. Incense cones were invented in Japan in the 1800s.

- Cored stick: This form of stick incense has a supporting core of bamboo. Higher quality varieties of this form have fragrant sandalwood cores. The core is coated by a thick layer of incense material that burns away with the core. This type of incense is commonly produced in India and China. When used for worship in Chinese folk religion, cored incensed sticks are sometimes known as "joss sticks".

- Solid stick: This stick incense has no supporting core and is completely made of incense material. Easily broken into pieces, it allows one to determine the specific amount of incense they wish to burn. This is the most commonly produced form of incense in Japan and Tibet.

- Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. They are typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

- Paper: Paper infused with incense, folded accordion style, lit and blown out. Examples are Carta d'Armenia and Papier d'Arménie.

- Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is highly transportable and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

The disks of powdered mugwort called 'moxa' sold in Chinese shops and herbalists are used in Traditional Chinese medicine for moxibustion treatment. Moxa tablets are not incenses; the treatment relies on heat rather than fragrance.

  

REED DIFFUSING

A reed diffuser is a form of incense that uses no heat. It comes in three parts: a bottle/container, scented essential incense oil, and bamboo reeds. The incense oil is placed into the container and bamboo reeds are then put into the same container. This is done to absorb some of the incense oil, as well as to help carry its scent and essence out of the container and into the surrounding air. Reeds typically have tiny tube openings that run the entire length of the stick. Oil is absorbed by the reed sticks and carried along the entire reed. These are do-it-yourself incense sticks that do not burn and look almost identical to typical incense sticks

 

PRODUCTION

INDIRECT BURNING

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, are then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition are made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

DIRECT BURNING

In order to obtain desired combustion qualities, attention has to be paid to certain proportions in direct burning incense mixtures:

 

- Oil content: Resinous materials such as myrrh and frankincense must not exceed the amount of dry materials in the mixture to such a degree that the incense will not smolder and burn.[citation needed] The higher the oil content relative to the dry mass, the less likely the mixture is to burn effectively.[citation needed] Typically the resinous or oily substances are balanced with "dry" materials such as wood, bark and leaf powders.

- Oxidizer quantity: The amount of chemical oxidizer in gum-bound incense must be carefully proportioned. If too little, the incense will not ignite, and if too much, the incense will burn too quickly and not produce fragrant smoke.

- Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

- Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

- Binder: Water-soluble binders such as "makko" have to be used in the right proportion to ensure that the incense mixture does not crumble when dry but also that the binder does not take up too much of the mixture.

 

Some kinds of direct-burning incense are created from "incense blanks" made of unscented combustible dust immersed into any suitable kind of essential or fragrance oil. These are often sold in America by flea-market and sidewalk vendors who have developed their own styles. Such items are often known as "dipped" or "hand-dipped" incense. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia, then simply scented with essential oils.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo cores of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. Through this process, known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and then continuously split in halves until thin sticks of bamboo with square cross sections of less than 3mm This process has been largely been replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

- Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

- Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are then evenly separated, then dipped into a tray of incense powder, consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the stick while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks that are burned in temples of Chinese folk religion produced in this fashion can have a thickness between 2 and 4 millimeters.

- Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more commonly found due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

JOSS STICKS

Joss sticks are the name given to incense sticks used for a variety of purposes associated with ritual and religious devotion in China and India. They are used in Chinese influenced East Asian and Southeast Asian countries, traditionally burned before the threshold of a home or business, before an image of a Chinese popular religion divinity or spirit of place, or in small and humble or large and elaborate shrine found at the main entrance to each and every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door, or open window as an offering to heaven, or devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

Joss-stick burning is an everyday practice in traditional Chinese religion. There are many different types of joss sticks used for different purposes or on different festive days. Many of them are long and thin and are mostly colored yellow, red, and more rarely, black. Thick joss sticks are used for special ceremonies, such as funerals. Spiral joss sticks are also used on a regular basis, which are found hanging above temple ceilings, with burn times that are exceedingly long. In some states, such as Taiwan, Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon joss sticks are sometimes used. These generate such a massive amount of smoke and heat that they are only ever burned outside.

 

Chinese incense sticks for use in popular religion are generally without aroma or only the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum.[citation needed] Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Despite the fact that they contain no sandalwood at all, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are only used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, aloeswood, or floral scents used. The Sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, Buddhism in Sri Lanka, Buddhism in Burma and Korean Buddhism do not use incense.

 

BURNING INCENSE

For indirect-burning incense, pieces of the incense are burned by placing them directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉?) is used by several Buddhist sects. The egōro is usually made of brass with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as Sonae-kō (Religious Burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. Flames on the incense are then fanned or blown out, with the incense continuing to burn without a flame on its own.

 

CULTURAL VARIATIONS

CHINESE INCENSE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life.

 

Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The poet Yu Jianwu (487-551) first recorded them: "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

 

It is incorrect to assume that the Chinese only burn incense in the home before the family shrine. In Taoist traditions, incense is inextricably associated with the 'yin' energies of the dead, temples, shrines, and ghosts. Therefore, Taoist Chinese believe burning undedicated incense in the home attracts the dreaded hungry ghosts, who consume the smoke and ruin the fortunes of the family.

 

However, since Neolithic times, the Chinese have evolved using incense not only for religious ceremonies, but also for personal and environmental aromatherapy.

 

INDIAN INCENSE

Incense stick, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, is one of the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepal/Tibet and Japanese methods of stick making which don't use a bamboo core. Though the method is also used in the west, particularly in America, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder - an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India which take raw unperfumed sticks hand-rolled by approx 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale.[38] An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 main companies who together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Bangalore.

 

In the Middle East, incense burning has been along tradition. The word bukhur means incense in Arabic. The well known choice for incense is the famous agarwood which is very popular in Africa, the Gulf and amongst some south Asians, but there are many many more choices. Incense come in a variety of forms such as blocks, pieces, pellets, granules or powdered, which is placed in the oil burner called mabkharah for several minutes to heat either with coal in the traditional way or via power in the modern way, allowing it to release its rich smell. However this takes awhile and the quick alternative is to use incense sticks called Oud in Middle East and Africa, and agarbatti in south Asia - again referring to the agar wood + batti meaning some sort of agar-stick. Occasionally some get confused between bukhur and oud, bukhur is the insence ie agarwood, sandlewood etc and oud being the incense sticks (and not the otherway round sometimes wires get twisted)

 

JERUSALEM TEMPLE INCENSE

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus as a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN INCENSE

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, or sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE INCENSE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like Calligraphy, Ikebana, and Scroll Arrangement. However the art of incense appreciation or Koh-do, is generally practiced as a separate art form from the tea ceremony, however usually practiced within a tea room of traditional Zen design.

 

Agarwood (沈香　Jinkō) and sandalwood (白檀　Byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "Jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation.[citation needed] It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

- Incense Arts: [香道, Kodo]

- Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

- Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

- Charcoal: [木炭] – only the odorless kind is used.

- Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

Incense is used for a variety of purposes, including the ceremonies of all the main religions, to overcome bad smells, repel insects, purify or improve the atmosphere, aromatherapy, meditation, and for simple pleasure.

 

PRACTICAL

Incense fragrances can be of such great strength that they obscure other, less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. Another example of this use, as well as of religious use, is the giant Botafumeiro thurible which swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single, long handle on one side. It is important to note that the perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct combustion incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve and captivate several of the senses.

 

Incense made from materials such as citronella can repel mosquitoes and other aggravating, distracting or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors, and do not want the scent to linger.

 

AestheticMany people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the refined sensory experience. This use is perhaps best exemplified in the kōdō (香道?), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.ReligiousUse of incense in religion is prevalent in many cultures and may have their roots in the practical and aesthetic uses considering that many religions with not much else in common all use incense. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense [to ancestors/gods]), etc.

 

HEALTH

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and absorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. The emission rate decreases in the row Indian sandalwood > Japanese aloeswood > Taiwanese aloeswood > smokeless sandalwood.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, a study by several Asian Cancer Research Centers showed: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified the findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and cancer of the lung, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also had higher rates of a type of cancer called squamous-cell carcinoma, which refers to tumors that arise in the cells lining the internal and external surfaces of the body. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters ovary cells to be even higher than cigarettes.

 

Frankincense has been shown to cause antidepressive behavior in mice. It activated the poorly understood ion channels in the brain to alleviate anxiety and depression.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY:

 

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION:

 

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE:

 

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

 

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii) Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

 

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES:

 

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING:

 

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

 

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING:

 

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

 

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

 

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

 

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

 

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

 

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION:

 

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

 

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

 

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

 

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

 

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

 

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE:

 

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS:

 

ARABIAN:

 

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE:

 

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN:

 

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic

 

ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM:

 

KETORET:

 

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN:

 

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE:

 

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE:

 

PRACTICAL:

 

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC:

 

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS:

 

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE:

 

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

  

From Wikipedia, the free encyclopedia

 

The Satyanarayana is a Hindu religious observance. It is a ritual performed by Hindus before/on any major occasion like marriage, house warming ceremony etc. It can also be performed on any day for any reason. It finds first mention in skandha puran

In addition, it is said that a devotional performance of this puja will bear children to couples trying to start a family.

 

ri Satyanarayana Vratam, Puja are very popular in Andhra Pradesh India. Almost all Hindus, throughout Andhra Pradesh, have strong faith, belief, and devotion towards Sriman Narayana, an incarnation of Vishnu.

Daily, large numbers of devotees, many with families, visit the temple, offer prayers, perform this Vratam there, right in the temple. This place is one of the very important pilgrimages.

[edit]Procedure

   

A painting of Narayana (Vishnu) seated on lotus

The puja starts by a prayer to Lord Ganesha, to remove all obstacles that may occur as a result of incorrectly performing the puja. This is done by chanting all the names of Lord Ganesha and offering prasad (a food offering, usually consisting of one of Lord Ganesha's favorite foods - modak, a sugar and coconut mixture, or laddu) and the showering of flower petals.

Another part of the prayer involves a prayer to the Navagraha's - the nine important celestial beings in the universe. They consist of Surya (the Sun), Chandra (the moon), Angaaraka/Chevaai (Mars), Budha (Mercury), Guru aka Bruhaspati (Jupiter), Shukra (Venus), Sani (Saturn), Rahu (the head of the Demon snake), and Ketu (the tail of the Demon snake).

The rest of the puja consists of worship to Satyanarayana, an extremely benevolent form of Lord Vishnu. First "panchamritam" is used to clean the place where the deity is placed. After placing the deity in the correct position, Satyanaraya swami is worshipped. Names of Satyanarayana are chanted along with offering of a variety of prasad (including a mixture of milk, honey, ghee/butter, yogurt, sugar) and flower petals.

Another requirement of the puja is that the story of the puja be heard among all those observing and partaking in the puja. The story involves the origin of the puja, the benefits of it, and the potential mishaps that may occur with the forgetting performance of the puja.

The prayer concludes with an Aarti, which consists of revolving a small fire-lit-lamp in the vicinity of an image of the Lord. After the puja is over, participants and observers of the puja are required to ingest in the prasad that was offered and blessed by the Lord......

Sri Satyanarana Swami Katha:

Shri Satyanarayana katha (narrative) comes from the Skandha purana, Reva kaanda. Suta Maharshi narrated these stories, in Neimishaaranya to the Rishis who were performing a 1 ,000 year yagna for the benefit of mankind lead by Shounakji.

For those who observe the fast religiously and regularly, there are some great lessons to be learned from the ‘katha’ (narration)

This is shown by characters who ignored their promise to perform the puja after their wish had been fulfilled. They suffered as a result. Therefore one is to deduce that one must stick to the promise given to the Lord in exchange of the desire fulfilled by His Grace. One is not to ignore or/and forget the Lord’s Grace. Prasad is symbolic of God’s Grace which Kalavati ignored as she learned of her husband’s safe return.

One can understand her eagerness in wanting to be re-united with her beloved, but one must understand that if one forgets to be thankful for gifts received from the Lord, one would have to go through another test until one remembers to remember.

When the rich merchant is asked what the boat contains, he untruthfully replies ‘Only dry leaves’ and the Mendicant says ‘So be it’ The above incident tells us that the spoken word has power. What you speak, manifests. Hence one must not speak an untruth. Especially an inauspicious untruth.

In the last story one learns that no one is higher or lower in status in the eyes of the Lord. Hence one must accord respect to whoever it may be, who is taking the name of God. Katha details: Story 1:

Suta Maharshi narrated the stories. Once upon a time while travelling the three worlds, Narada Maharshi reached Bhoolokam (Earth) and saw the human beings immense suffering. He then went to the abode of Lord Sri Satyanarayana Swami (the benevolent form of Lord Vishnu), who alone can relieve the mankind from the sufferings. There he met the Lord Vishnu with four arms each with Shankha, Chakra, Gadha & Padma, wearing Tulsi Mala (garland) in his neck. Narada Maharshi then asked the lord for a panacea for the miseries of the world. Lord Sri Satyanarayana told Narada Maharshi that there is a fast and puja which can be performed by anyone to overcome these obstacles. The Lord said, “Anyone who performs Shri Satyanarayan Swami’s Vratham & Puja in the right way they will get all the pleasures on earth & will reach their goal”. The fast would result in the fulfillment of his desires and also liberation from the cycle of birth and death into attaining moksha (salvation). Whosoever performs Shri Satyanarayana Swami’s Katha with a Brahmin and with his family with full rites/rituals, they will be relieved off their sufferings and sorrows. They will be bestowed with wealth & wisdom, they will be blessed with children and they will get overall victory & increased devotion.

For this prayer, one requires ripe bananas, ghee, milk & choori (made with wheat flour, ghee & sugar). After the prayers, all present must have the prasadam & then take their meals together, & then sing, praise, & chant mantras of Shri Satyanarayana Swami. By doing this, their wishes will be fulfilled. This vratham in kaliyugam gives boon (reward) very quickly.

This chapter of Lord Satyanarayana Swami is over. All chant together (say) Shri Satyanarayana ki jai. Story 2:

Lord Satyanarayana then narrated to Narada Maharshi how and who performed the puja first. In a place named Sunder Kashipur, there used to live a very innocent brahmin. In hunger & thirst he used to roam begging for his daily bread. When the Lord saw the Brahmin in sorrow and begging daily, he disguised himself as an old Brahmin & asked him, “On Brahmana, why are you so sad. Please tell me all about your difficulties. Is there any way I could help you?”. The Brahmin replied, “I am a poor Brahmin & I roam daily for bread. Do you know if there is any way to come out of all this sorrow?”. Then the Lord in the guise of a brahmin said “Lord Satyanarayana grants all the wishes of all the people if his puja and fast is performed diligently. If you pray to him & keep his fast you will overcome all your sorrow and get moksha”. After telling him all the details of the prayer and the fast, Lord disappeared. The poor brahmin could not sleep that night. He kept thinking of the fast and the prayer which the Lord had asked him to do. In the morning, he woke up with the thought that somehow he must perform the puja and so thinking went out for his biksha (alms). On that day the Brahmin got a lot of money. He used to buy all the necessary things for the prayer. He called his family and performed Lord Satyanarayana’s prayer. By doing so, the Brahmin overcame all his sorrows & became rich. From then onwards, he performed the prayers every month without fail. Thus whoever performs Lord Satyanarayana Swami’s puja, they will be relieved from all sorrows.

The Lord then narrated another story. The same Brahmin now a rich person performed the prayer every month without fail with his family. Once a Brahmin was in between his prayer when a wood-cutter passed by. After keeping the bundle of wood outside the brahmin’s house, he went in to quench his thirst. The thirsty wood-cutter saw the brahmin performing the Satyanarayana Vratham. He bowed down to the Brahmin & asked him, “Oh Brahmana, what are you doing, please tell me.” The Brahmin replied, “I am performing the vratham of Lord Satyanarayana Swami. One who accomplishes this will overcome all obstacles and their wishes will be granted. They will attain wealth and wisdom. I have aquired my wealth also in the same way.” After hearing about the prayer and drinking the water, the wood-cutter felt happy. He ate the prasadam from the puja and left for his house.

Thinking of Lord Satyanarayana in his mind, he said “Whatever money I make from selling wood today, I will use it to perform the Satyanaraya Swami vratham.” So thinking, he loaded the bundle of wood onto his head and left for his home. Along the way home he went roaming in Sunder Nagar selling the wood. On that day, he got four times more money than what he made usually out of the wood sale. Feeling happy, he went and bought all the necessary things for the prayers (ie. ripe bananas, sugar, ghee, wheat flour, etc). On reaching his house and after cleaning himself, he called his family and did the prayer with due respect. He became rich and aquired all the pleasures of life. At the end of his life he went to heaven.

This story consists of a childless merchant and his adventures. There was a wise king named Ulkamuk. He had a pious and beautiful wife. He would go to the temple daily and would give charity to the Brahmins. One day near the banks of river Madhushala, where they were performing Lord Shri Satyanarayana’s vratham, a wealthy merchant was passing by. He anchored his boat, went to the king and asked him, “Oh King, please let me know the details about the vratham you are performing with such devotion”. The king replied that he was performing the Lord Satyanarayana Swami’s vratham. He said that one who performs this vratham will gain worldy pleasures and attain salvation. The merchant with much eager asked him the details stating that, “Oh King, I would like to know the details as I am childless and would like to perform this vratham”. The king gladly gave the entire details about the vratham and its vidhanam.

After aquiring the entire details of the vratham, the merchant and his wife decided to perform the fast if they get a child. Sometime later his wife Lilavati became pregnant and she delivered a girl who they called Kalavati. The merchant’s wife Lilavati reminded him about his promise to keep the fast and perform the vratham. The merchant postponed it saying that he would do so when the daughter is ready to be married. The merchant told his wife that during the time of Kalawati’s wedding it would be easy to the fast for at the moment he was busy in his business. So saying he left for his business trip to various villages.

Kalawati grew up to be a beautiful girl. When the merchant saw his daughter was of marriageable age; he called the match-maker and requested him to search an ideal match for his daughter. Hearing the merchant’s request, the match-maker reached Kanchan Nagar. From there, he brought the proposal of a young handsome boy. Agreeing to the proposal and after speaking to the boy’s parents, Kalavati’s marriage was performed with much fanfare and religious ceremonies & rituals. All this while the merchant forgot about the promise to perform the Satyanarayana vratham and so the Lord decided to remind the merchant about his promise.

The merchant, after a few days, left for his business trip with his son-in-law by boat. They anchored their boat in a beautiful village, named Ratanpur ruled by King Chandraketu. One day, the thieves robbed the wealth of the king. After robbing they went and stayed at the same place where the merchant was staying. Seeing the guards following them, they left the entire loot near the merchant and then hid themselves. When the guards reached the merchant’s place, they saw all the king’s wealth beside the merchant and his son-in-law. Thinking them to be robbers, they arrested them and brought them before the king stating that they were responsible for the theft. The king, without giving any chance of explaining their case ordered both be confined to behind bars. Even their wealth was confiscated by the king.

While at the merchant’s house, the thieves robbed their entire wealth. This left his wife and daughter to beg for their daily bread. One day while begging for food, Kalawati reached a Brahmin’s house. At that time the brahmin and his family were performing Lord Satyanarayana’s puja. After listening to the prayer and& taking the prasadam, she left for home. By the time she reached home it was already dark.

Leelawati was worried. She asked her daughter Kalawati, why it took her so much time to come home. Kalawati replied, “Oh Mother, today I was at a Brahmin’s house where they were performing Lord Satyanarayana’s vratham.” On hearing this, Leelawati recollected the long pending promise by her husband and narrated it to her daughter. She soon began the preparations for the Lord Satyanarayana vratham. She did the fast & prayer and asked the Lord for forgiveness. She prayed that her husband and her son-in-law return home safely.

Lord Satyanarayana was pleased with the prayer and the fast. One day, he told King Chandraketu in his dream, “Oh King, You must release the merchant and his son-in-law as they are not the robbers. Return their wealth and set them free. If you do not do so, your kingdom will be destroyed.” In the morning, the king called the people in his court and told them about the dream.

The people they agreed that the merchant and his son-in-law should be released by the king. The king asked the guards to bring the prisoners returned all their belongings and set them free. The king told them that due to their wrong-doings, they had to undergo this suffering, but now there was nothing to fear & they could go back home. They bowed down to the king & left for home.

The merchant prayed first and then gave some wealth to the Brahmin before starting his journey for home. When they went little further, Lord Satyanarayana wanted to test them. He disguised as an old man and went up to the merchant. The Lord asked, “What is in your boat, give me little from there.” The merchant in arrogance and pride, replied, “Oh Old man, we have nothing in our boat except hay and leaves.” On hearing such harsh words from the merchant, the Lord said, “Your words shall be true”. So saying, he went from there and sat on the bank of the river.

When the Lord went away, the boat started to rise higher in the water. The merchant was surprised at this. He went to check inside the boat. To his shock he saw that his boat which was filled with his wealth now contains only leaves and hay. Seeing this he fainted. When he came to his senses, he said “How could this happen?” His son-in-law meanwhile told him, “Do not cry over this. All has happened because you spoke harshly to the old man and lied to him. Still, nothing is lost. You could go back to him and ask him for his forgiveness. He may set everything right.”

The merchant, after hearing the words of his son-in-law went in search of the old man. He bowed down before him and with respect said, “Oh Lord, please forgive me for the words I have spoken.” So saying, he bowed down with tears of sorrow in his eyes. When the Lord, saw the merchant in his state of sorrow and crying for forgiveness, he said, “Oh foolish person, due to your deeds, you have seen all this sorrow & suffering.”

On hearing the merchant’s words filled with bhakti, the Lord was happy & he turned the boat full of wealth. When the merchant mounted his boat and saw it full with wealth again, he thanked the Lord & said, “With Lord Satyanarayana’s grace, my wish is fulfilled. When I reach home, I will do his prayer & fast”, so saying he left for his home.

When the merchant saw that his home-town Ratanpur is nearing, he sent a messenger in advance, to his house to inform his wife & daughter of his arrival. The messenger, on reaching the merchant’s house, bowed down to the merchant’s wife & gave them the most awaited news that the merchant & his son-in-law have reached Ratanpur.

Leelawati had just finished doing her Satyanarayana Puja meanwhile. She told her daughter to finish doing the prayer and then come & receive her husband & her father. Kalawati finished doing her quickly & without taking the prasadam left to meet her husband. The Lord got angry at her for this, and so he drowned her husband with the boat. When Kalawati did not see her husband; she was shocked and she fainted on the floor.

On seeing his daughter and the sudden disappearance of the boat, the merchant was shocked. He prayed to Lord Satyanarayana, asked him for his forgiveness and prayed to the Lord to take them out of this difficulty. The Lord said to the merchant, “Oh merchant, your daughter, in a hurry to meet her husband has left my prasadam. When she goes back and takes the prasadam with due respect only then she will see her husband.” On hearing this, Kalawati ran home, ate the prasadam offered respects to Lord Satyanarayana and came back to meet her husband. When the merchant saw this, he was very happy.

The merchant then performed Lord Satyanarayana’s vratham with his family every month from then onwards. They all gained the pleasures of life and after their death they got the ultimate gift of ‘Moksha’ (Salvation – Liberation from the cycle of life and death).

Suta Maharshi continuing his narrative, tells the Rishis, the story of a king called Angadwaja. Once, as King Angadwaja was returning from a hunting expedition, he stopped to rest under a tree for a while. Nearby a small group of cowherd boys were playing the game of doing puja. They offered their humble parsadam to the king, who out of pride left it untouched. Subsequently the king suffered great losses and realised that that was due to the contempt he had shown for those children’s puja. The king realising his mistake returned to the spot where he had met the cowherds, and with great faith performed the puja with them. The king regained all that he had lost.

Suta Maharshi now told the Rishis that the Lord Sri Satyanarayana Swami fast was very effective during Kaliyuga and that whoever read or heard this story would be rid of all sorrows and difficulties.

The names of the persons who kept Satyanarayana vratham took re-birth are as follows:

The Brahmin took birth as Sudama & in his entire life he served the Lord Krishna & attained moksha.

King Ulkamuk took birth as King Dashrath, and in that life he became the father of Lard Rama & attained eternity.

The merchant took birth as King Morad, who cut his son in half & offered to the Lord & got moksha.

King Angadwaja took birth as Kewat, who took Lord Rama across the river, served him & got moksha.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Agarbathi :

India has a rich tradition of incense making that goes back millennia. Many Indian incenses have a unique scent that is not found in any other part of the globe. Incense sticks formed around bamboo are known as agarbatti or agarbathi, while other main forms of incense are cones and logs or dhoops, which are incense paste formed into pyramid shapes or log shapes, and then dried. Thus, modern, organized incense-making is intrinsically linked to the Ayurvedic medical system in which it is rooted.

Oil Lamp or Kuthu Vilakku

The lamp has its own special place. It is a form and a symbol of Tej (Absolute fire principle); the lamp leads us from darkness towards light. It burns only to give message of peace and light to the human. This is its greatness. Agni Puran clearly states that only oil or Ghee (clarified butter) be used in the lamp meant for puja and no other combustible substance. According to the Science of spirituality the lamp with clarified butter is more sattvik (spiritually pure) as compared to lamp in which oil is used. According to yogic path of Kundalini Yog there are seven principle chakras or energy centers in the human being. These chakras influence practically every aspect of human being including physical body, mind and intellect.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

An Art Nouveau Incense Burner.

 

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY:

 

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION:

 

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE:

 

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

 

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

 

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES:

 

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING:

 

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odour.

 

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING:

 

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

 

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

 

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

 

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

 

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION:

 

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

 

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

 

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

 

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

 

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimetres.

 

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE:

 

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS:

 

ARABIAN:

 

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE:

 

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

 

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN:

 

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM:

 

KETORET:

 

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN:

 

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE:

 

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE:

 

PRACTICAL:

 

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC:

 

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS:

 

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE:

 

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

HISTORY:

 

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION:

 

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE:

 

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii) Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

 

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES:

 

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING:

 

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odour.

 

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING:

 

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

 

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION:

 

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

 

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE:

 

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS:

 

ARABIAN:

 

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE:

 

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN:

 

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM:

 

KETORET:

 

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN:

 

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE:

 

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE:

 

PRACTICAL:

 

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC:

 

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS:

 

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE:

 

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities.

During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

ARABIAN

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.

 

CHINESE

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

 

Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.

Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,

 

Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.

 

Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

 

JEWISH TEMPLE IN JERUSALEM

KETORET

Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.

 

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

 

WIKIPEDIA

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.

 

Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.

 

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.

 

HISTORY

The word incense comes from Latin incendere meaning "to burn".

 

Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

 

The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.

 

Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.

 

At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.

 

Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.

 

COMPOSITION

A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.

 

Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.

 

COMBUSTIBLE BASE

The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:

 

Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.

Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:

Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)

Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.

Jigit: a resin based binder used in India

Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.

 

Typical compositions burn at a temperature between 220 °C and 260 °C.

 

TYPES

Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.

 

INDIRECT-BURNING

Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.

 

Whole: The incense material is burned directly in raw form on top of coal embers.

Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.

Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.

 

DIRECT-BURNING

Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.

 

Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.

 

Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.

Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".

Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.

Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.

Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.

Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.

 

Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.

Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.

 

PRODUCTION

The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.

 

Certain proportions are necessary for direct-burning incense:

 

Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.

Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.

Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.

Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.

Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.

 

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.

 

Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.

 

Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.

 

In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:

 

Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.

Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.

Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.

 

BURNING INCENSE

Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.

 

In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).

 

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

 

CULTURAL VARIATIONS

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور‎ [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad.

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.

Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.

 

Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.

 

INDIAN

Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.

 

The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.

TIBETAN

Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.

 

Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.

 

JAPANESE

In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.

 

Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.

 

Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.

 

Some terms used in Japanese incense culture include:

 

Incense arts: [香道, kodo]

Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.

Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning

Charcoal: [木炭] – only the odorless kind is used.

Incense woods: [ 香木 ] – a naturally fragrant resinous wood.

 

USAGE

PRACTICAL

Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.

 

A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.

 

The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.

 

Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.

 

Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.

 

Incense is also used often by people who smoke indoors and do not want the smell to linger.

 

AESTHETIC

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.

 

RELIGIOUS

Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.

 

Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.

 

Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.

 

Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.

 

HEALTH RISK FROM INCENSE SMOKE

Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.

 

Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.

 

A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.

 

In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."

 

Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."

 

In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.

 

Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.
