Mrs Darukhanawalla is a very kind Parsi lady who has a sandalwood and agarbatti shop next to the Tata Agiary Bandra Hill Road.
We have known each other since a very long time, right from the days she used to see me drinking away early mornings at the Iranis a beer joint now defunct..at Bandra opposite the old New Talkies now the Globus mall.
It was here where all hardcore early morning tipplers of Bandra met for the Uttara..
Beer was served here or booze that was peg system.
You could have brun and kheema as acccompaniment..
Mrs Darukhanawalla would see me and give me a smile but always praying that I get out from the clutches of my alcoholic stupor..
I did and so Mrs Darukhanawalla who stays at Bandra Chinchpokli Road is a very special person.
Mrs Darukhanawalla died this year..

I always had confusion between faith and belief, i always mix them up. Today i was into one such situation and obviously got confused. Confused me started searching for definitions of faith and belief, this search got extended from finding definitions to finding interesting quotes (thanks to Google, its creatively making me lazy). Below are some interesting quotes i came across :)
>> Faith is not belief. Belief is passive. Faith is active.
- Edith Hamilton
>> Belief is a truth held in the mind; faith is a fire in the heart.
- Joseph Fort Newton
>> Belief is a wise wager (bet). Granted that faith cannot be proved, what harm will come to you if you gamble on its truth and it proves false? If you gain, you gain all; if you lose, you lose nothing. Wager, then, without hesitation, that He exists.
- Blaise Pascal
My confusion still continues...... :O

Varanasi, also known as Kashi or Banaras, is a city to die for...literally! According to the Hindu mythology & beliefs, a preson attains Moksh, or Nirvana, if he or she dies in this holy city. Apart from the tall tales, the historic & holy city is a traveler & a photographer's delight, with the Ganga Aarti performed in the dusk at Dasaswamedh Ghat, near the famous Kashi Vishvanath temple, on the banks of the mighty river Ganga, surely the highlight of the city. Thousands of pilgrims & travelers flock the ghat in the evening to witness this spectacular Aarti performed by seven young Pandits.
The Aarti which I witnessed was performed in a steady drizzle, which neither fazed the Pandits, nor the pilgrims, who kept on chanting Har Har Gange along. The Aarti which commenced with the blowing of a Shankh (a conch shell) and continued with the waving of Agarbattis (incense sticks) in elaborate patterns and circling of large flaming lamps that created bright star spikes as rain pattered on my lens. The heady scent of sandalwood & burning Camphor smoke thickly permeated the air to a mesmerizing frame. A magical evening on the Ghats of the holy Ganga.
en.wikipedia.org/wiki/Lal_Shahbaz_Qalandar
Hazrat Lal Shahbaz Qalandar (1177–1274) (Sindhi: لال شھباز قلندر), a Persian (Tajik) Sufi saint, philosopher, poet, and qalandar. Born Syed Usman Shah Marwandi,[1] he belonged to the Suhrawardiyya order of Sufis. He preached religious tolerance among Muslims and Hindus. Thousands of pilgrims visit his shrine every year, especially at the occasion of his Urs.
Life
Shahbaz Qalandar (Shaikh Usman Marwandi) was born in Marwand, Afghanistan[2] to a dervish, Syed Ibrahim Kabiruddin[3] whose ancestors migrated from Baghdad and settled down in Mashhad, a center of learning and civilization, before migrating again to Marwand.
A contemporary of Baha-ud-din Zakariya, Fariduddin Ganjshakar, Syed Jalaluddin Bukhari Surkh-posh of Uchch, Shams Tabrizi and Rumi, he travelled around the Muslim world settled in Sehwan (Sindh, Pakistan) and was buried there.[4]
His dedication to the knowledge of various religious disciplines enabled him to eventually become a profound scholar. During his lifetime, he witnessed the Ghaznavid and Ghurids rules in South Asia.[5] He became fluent in many languages including Persian, Turkish, Arabic, Sindhi and Sanskrit. His mysticism attracted people from all religions. He was called Lal (red) after his usual red attire, Shahbaz due to his noble and divine spirit, and Qalandar for his Sufi affilitation. Hindus regarded him as the incarnation of Bhrithari. Lal Shahbaz lived a celibate life.
Evidence shows that Shahbaz Qalander was in Sindh before 1196, when he met Pir Haji Ismail Panhwar of Paat; it is believed he entered Sehwan in 1251. Shahbaz Qalander established his Khanqah in Sehwan and started teaching in Fuqhai Islam Madarrsah; during this period he wrote his treatises Mizna-e-Sart, Kism-e-Doyum, Aqd and Zubdah.
In poetry and prose
A qawwal sung by Abida Parveen and many others, "Lal Meri Pat Rakhiyo ..." is in honour of Shahbaz Qalandar, as is one sung in various versions by Nusrat Fateh Ali Khan and the Sabri Brothers, "Mast Qalandar".
This famous mystic often quoted the teachings of Maulana Jalal ad-Din Rumi. A book detailing his life is called "Solomon's Ring" by Gul Hasan.
Bu Ali Shah Qalandar's famous Persian verses showing his love and honour for Hazrat Ali are engraved on his shrine:
“Haiderium Qalandram Mastam
Banda e Murtaza Ali Hastam
Peshwa e tamam Rindanam
Ke Sag e Koo e Sher e Yazdanam!”
Translation:
I am Haideri (relating to Haider, a second name for Ali ibn Abi Talib), Qalandar and Mast (intoxicated)
I am a servant of Ali Murtaza
I am leader of all saints
Because I am a dog of the lane of "Allah's Lion" (referring to Ali Murtaza)
Legends and Stories
On his way from Baluchistan to Sindh, he also stayed in present day Karachi's Manghopir area for muraqba (meditation), and it is said that Manghopir's natural warm fountain is a miracle of Lal Shahbaz Qalandar. That warm fountain started to flow from beneath the hill, on which Lal Shahbaz sat for muraqba (meditation). After passing hundreds of years, that warm fountain is still flowing continuously and is said to have miraculous healing power especially for asthma patients.
In Multan, Lal Shahbaz met Bahauddin Zachariah Multani of the Suhurwardiya order, Baba Farid Ganjshakar of Chishtiya order, and Makhdoom Jahanian Surkh Bukhari. The attachment was so cordial and spiritual that their friendship became legendary. They were known as Chahar Yar (Persian = four friends). According to some historians, the four friends visited various parts of Sindh and Punjab, in present day Pakistan.
Many saints of Sindh, including Shah Abdul Latif Bhitai, Makhdoom Bilawal and Sachal Sarmast, were devout followers of Lal Shahbaz Qalandar.
It is also believed that he turned into a falcon to pick up his friend Fariduddin Ganjshakar from the gallows. The legend goes that the incumbent fakirs in Sehwan sent him a bowl of milk filled to the brim, indicating that there was no room for anything more. But surprisingly, he returned the bowl with a beautiful flower floating on the top. This legend spread far and wide by the time of his death in 1274, after living a good span of 97 years.
Shrine
The shrine around his tomb, built in 1356, gives a dazzling look with its Sindhi kashi tiles, mirror work and one gold-plated door - donated by the late Shah of Iran, and installed by the late Prime Minister Zulfikar Ali Bhutto.[2] The inner sanctum is about 100 yards square with the silver canopied grave in the middle. On one side of the marble floor is a row of about 12-inch-high (300 mm) folding wooden stands on which are set copies of Quran for devotees to read. On the other side, beside a bundle of burning agarbattis (joss sticks), are rows of diyas (small oil lamps) lighted by devotees.
Urs
His annual Urs (death anniversary celebration) is held on the 18 Sha'aban - the eighth month of the Muslim lunar calendar. Thousands of devotees flock to the tomb while every Thursday their number stands multiplied especially at the time of his ‘Urs’ being a carnival as well a religious festival and celebrated every year. Sehwan springs to life and becomes the focal point of more than half a million pilgrims from all over Pakistan. On each morning of the three day feast, the narrow lanes of Sewhan are packed to capacity as thousands and thousands of pilgrims, fakirs and devotees make their way to the shrine to commune with the saint, offer their tributes and make a wish. Most of the people present garlands and a green chadar (a cloth used to cover a tomb) with Qur’anic inscriptions in silver or gold threads. Humming of verses, singing and dancing in praise of the saint continues till late at night. A devotional dance known as ‘dhamal’, being a frenzied and ecstatic swirl of the head and body, is a special ritual that is performed at the rhythmic beat of the [dhol] (a big barrel-shaped drum), some of them being of giant size and placed in the courtyard of the shrine. Bells, gongs, cymbals and horns make a thunderous din, and the dervishes, clad in long robes, beads, bracelets and colored head-bands whirl faster and faster in a hypnotic trance, until with a final deafening scream they run wildly through the doors of the shrine to the courtyard beyond.
Hindu symbols and offerings are all derived from nature...fruits, flowers, leaves, spices, water. It appeals to all senses...there is color, smell, touch and sound. Here, the coconut symbolises fertility, prosperity. Turmeric, a 4000 year old spice has many medicinal and nutritive properties. Rice was a staple in India from ancient times. Incence purifies the atmosphere, induces a good environment for meditating. The oil lamp banishes darkness. Fruits are the most nutritious and basic food offered by nature. This not really out of any book but from what I have absorbed as part of this culture. You are welcome to contradict or contribute to this !!

A sad CNE blog Oct. 2020: www.blogto.com/city/2020/09/cne-close-permanently-deficit...
A variety of incense cones which thankfully were not overly sweet. I am sad to have likely lost this annual Toronto ON sconce of incense cones.
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.
(sadhu)'baba' was all that everybody called him. this was the first glimpse of him, getting ready for the holy bath.
baba lives on the narmada bank, in small hut. as per daily routine, he bath, wash cloths and worship the holy narmada, everyday after sunrise and before sunset. then after he get lost in prayer and other religious rituals in his hut. if someone provide food he will eat, otherwise, fresh air smelling 'agarbatti' and 'diya' is enough for him. in the picture is 70% of the things (walking stick is submerged rightnow) he needs and possess, rest 30% is all that is required to worship god, in his dwelling.
i was about half an hour here, speechless, seeing the simplicity in self-sufficiency. all that i could say him was 'pranam'. and for the whole time a line came to my mind "happiness is in what you have, not in what you want."

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.

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.

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.

Ceramic Buddha Incense Burner. I burned three incense cones at once in order to obtain this volume of incense smoke.
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 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 burnt. The term is used for either the material or the aroma. Incense is used for aesthetic reasons, religious worship, aromatherapy, meditation, and ceremony. It may also be used as a simple deodorant or insect repellent.
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. The purpose of the usage of incense stick varies; some human beings use it for the duration of meditation and rituals, even as some use it to kill insects. 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. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians. Some incense, depending on the contents, may also act as organic insect repellent. In Hinduism, , . an integral part of most rituals. The name is derived from agarwood which is commonly used in incense production.
The oldest source on incense is the Vedas, specifically, the Atharva-veda and the Rigveda. Incense-burning was used both to create pleasing aromas and a medicinal tool. Its use in medicine is considered the first phase of Ayurveda, which uses incense as an approach to healing. Incense-making was thus almost exclusively done by monks.The practice of incense as a healing tool was assimilated into the religious practices of the time. As Hinduism matured and Buddhism was founded in India, incense became an integral part of Buddhism as well. Around 200 CE, a group of wandering Buddhist monks introduced incense stick making to China. Some incense, depending on the contents, may also act as organic insect repellent.
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, 香道) 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 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 resin or oils extracted from fragrant material, 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.
VIETNAM
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 centimetre) 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 metre 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 millimetres 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 is 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 [baˈxuːɾ]). 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 (Arabic: مبخر or مبخرة), 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 (مجلس, '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 (沉香; chénxiāng) and sandalwood (檀香; 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.
MALAYSIA
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.[citation needed] 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 agarbattī (Hindi: अगरबत्ती) 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.
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 (Hebrew: קְטֹרֶת) 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. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. Kōdō (香道), the art of incense appreciation, 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. The characters in agarwood mean "incense that sinks in water" due to the weight of the resin in the wood. Sandalwood is used in the Japanese tea ceremony. The most valued sandalwood comes from Mysore in the state of Karnataka in India.
Japanese incense companies divide agarwood into six categories depending on its properties and the region from which it is obtained. Kyara (伽羅), a type of agarwood, is currently worth more than its weight in gold.
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 jìngxiāng (敬香, 'offer incense [to ancestors/gods]'), 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 “smoke cleansing” 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 RISKS FROM INCENSE SMOKE
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NO
x), sulfur oxides (SO
x), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between around 10 and 500 nanometres. 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. 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
Brass incense burner purchased at the Arab market in Jerusalem. John Maguire, master tinsmith at Black Creek Pioneer Village, Toronto, made a round copper disc with punched holes which is a much better platform on which to burn the incense.
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 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, Latin: incendere, "to burn", is composed of aromatic biotic materials, which release fragrant smoke when burned. The term "incense" refers to the substance itself, rather than to the odor that it produces. It is used in religious ceremonies, ritual purification, aromatherapy, meditation, for creating a mood, masking bad odours, and in medicine.

THE HISTORY OF INCENSE:
The word "perfume" comes from Old Provincial French perfumar - per "through" and fumar "to smoke". This explains the art of perfumery, believed to have begun in the Middle East with the burning of incense. The use of incense dates back to biblical times and may have originated in Egypt, where aromatic trees were imported from Arabia to be used in religious ceremonies.
Ganjin, a Buddhist priest from Tang China, reached Japan in 754 AD. This venerable priest, well known for introducing Buddhist precepts into Japan, should also be remembered for his accomplishment in the history of incense. through medical incense and the skill of nerikoh (blended incense balls), Ganjin introduced a thriving incense culture from Tang dynasty China into Japan.
Takimono, a kind of nerikoh, is made of powdered incense for medical use, together with binding substances such as nectar and treacle. there was no fragrance incense before nerikoh in Japan, and people used to burn medical incense to generate fragrances. As nerikoh is a mixture of ingredients, different mixtures created subtly different fragrances. As a result, people made their own favorite fragrances from original concoctions. In this context, incense was no longer used as a religious offering, but as a tasteful pleasure called soradakimono designed for the enjoyment of graceful aromas. This was the start of the esthetic and artistic world of graceful incense-burning in Japan.
Court nobles in the Heian period (8th to 12th centuries) concocted original takimono in search of graceful and sophisticated fragrances for personal use. Different blends were used for different times, occasions or seasons, according to the mood of the moment. To impregnate their clothes or suffuse their rooms for guests, court people burnt their favorite blend of incense. “Takimonoawase”, an incense game where participants competed to produce better fragrances, also started in this period. Not quite satisfied with the simple fragrances of flowers and fruits in nature, court nobles created fragrances for their pleasure, thus establishing the foundation of a peculiar incense culture that was firmly attached to a keen awareness of the seasons. This is how the essential quality of Koh-Do (“the Way of Incense”) was formed.
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.

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.
Good morning friends
As you are aware I was infected with #shingles #herpeszoster or as we call it #nagin
I am being treated by #allopathy but this morning I went to a traditional healer a Christian who does #jhadna through #mantras agarbatti neem leaves .He lit the agarbbatis t.co/kEzg0Z6zkN
Than he swept my torso back with neem leaves than he began reciting mantras his Guru was a Hindu healer.
He told me the leaves should not come under the feet so I put in a garbage bin now two more sessions remain.
#bandrabazar
He also gave me a few dried seeds to dip in water and apply on the blisters he did not tell me the name of the seed though I applied fresh aloe vera leaf too
I got a message there is a #leechtreatment too froma friend .
I will continue with the #jhadna .
Shot @ Varanasi/Benaras (Kashi), Uttar Pradesh, India.
Ganga Puja is an other main attraction of Varanasi, UP, India. Puja will be performed everyday evening between 6pm to 7pm @ Dasashvamedha Ghat. Huge number of tourist / devotees will gather at this Ghat to watch this event. The worship begins with Bhajan, where the priest and devotee sing along for Godess Ganga and Lord Shiva. Normally the Hindu religious ceremony & spiritual rites starts with Agarbatti (scented smoke).
Btw, i have started doing shoots for clients.. so, if anyone is interested in getting their family/kids/teens/bridal portraits done.. you can mail me at sowmya0304@gmail.com
I opened one package and the scent from the sticks overpowered the air for hours.
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.

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.

Gaya (/ɡʌjɑː/) is a city of ancient historical and mythological significance. It is one of the major tourist attractions of Bihar. Gaya is the 2nd largest city of Bihar, with a population of 470,839, and is also the headquarters of Gaya district and Magadh division.
Gaya is 100 kilometres south of Patna, the capital city of Bihar. Situated on the banks of the Phalgu River (or Niranjana, as mentioned in Ramayana), it is a place sanctified by the Jain, Hindu, and Buddhist religions. It is surrounded by small rocky hills (Mangla-Gauri, Shringa-Sthan, Ram-Shila and Brahmayoni) by three sides and the river flowing on the fourth (eastern) side. The city has a mix of natural surroundings, age old buildings, green areas and narrow bylanes.
Gaya finds mention in the great epics, Ramayana and Mahabharata. Rama, along with Sita and Lakshmana, visited Gaya to offer pind-daan to their father Dasharath. In the Mahabharata, the place is referred to as Gayapuri. About the origin of the name ‘Gaya' as referred to in Vayu Purana is that Gaya was the name of a demon (Asura) whose body was pious after he performed rigid penance and secured blessings from Vishnu. It was said that the Gayasura's body would continue to be known as Gaya Kshetra.
ORIGIN OF NAME
Gaya derives its name from the mythological demon Gayasur (which literally means Gaya the demon). According to Vayu Purana, Gaya was the name of a demon (Asura) whose body was pious after he performed rigid penance and secured blessings from Vishnu. It was said that the body of Gayasura was transformed into the series of rocky hills that make up the landscape of Gaya.
HISTORY
ANCIENT HISTORY
Gaya is an ancient city. Documented history of Gaya dates back to the enlightenment of Gautama Buddha. About 11 km from Gaya town is Bodh Gaya, the place where Gautam Buddha attained enlightenment. Gautam Buddha was a sage on whose teachings, the religion Buddhism was founded. Since then Gaya has been a place of pilgrimage for people all over the world. Gaya further flourished under the rule of dynasties like the Mauryans who ruled from Pataliputra (modern Patna) and covered the area beyond the boundaries of the Indian subcontinent. During this period, Gaya was a part of the Magadh region.
Gaya experienced the rise and fall of many dynasties in the Magadh Region. From the 6th century BC to the 18th century AD, about 2300–2400 years, Gaya has been occupying an important place in the cultural history of the region. It opened up with the Sisunaga dynasty founded by Sisunaga, who exercised power over Patna and Gaya around 600 BC. Bimbisara, fifth in line, who lived and ruled around 519 BC, had projected Gaya to the outer world. Having attained an important place in the history of civilisation, the area experienced the bliss of Gautam Buddha and Bhagwan Mahavir during the reign of Bimbisara. After a short spell of Nanda dynasty, Gaya and the entire Magadha region came under the Mauryan rule with Ashoka (272 BC – 232 BC) embracing Buddhism. He visited Gaya and built the first temple at Bodh Gaya to commemorate Prince Gautama's attainment of supreme enlightenment.
The period of Hindu revivalism commenced with the coming of the Guptas during the 4th and 5th century A.D. Samudragupta of Magadh helped to bring Gaya in limelight. It was the headquarters of Bihar district during the Gupta empire.
Gaya then passed on to the Pala Empire with Gopala as the ruler. It is believed that the present temple of Bodh Gaya was built during the reign of Dharmapala, son of Gopala.
Gaya, in the 12th century, was invaded by Muhammad Bakhtiyar Khilji. It remained a part of the mughal empire till the place finally passed on to the Britishers after the battle of Buxar in 1764. Gaya, along with other parts of the country, won freedom in 1947.
MODERN HISTORY
The town of Gaya, in about 1810 AD, consisted of two parts : one the residence of the priests, which properly was called Gaya; and the other the residence of lawyers and tradesmen, which was originally called Elahabad, but later on, as developed by a renowned collector "Saheb" - Mr. Thomas Law, it was called Sahebgunj. It is the birthplace of eminent nationalist Bihar Vibhuti Dr Anugrah Narain Sinha; Bihar's first deputy Chief Minister cum Finance Minister. The last great ruler of Magadha was Maharaja of Tekari. The leader of Kisan Andolan, Swami Sahajanand Saraswati established an ashram at Neyamatpur, Gaya (Bihar) which later became the centre of freedom struggle in Bihar. Many prominent leaders of Indian National Congress visited there frequently to meet Yadunandan (Jadunandan) Sharma, the leader of Kisan Andolan who resided in the ashram set up by Swamiji. Yadunandan Sharma became the undisputed leader of peasants in the Gaya district and second in command to the legendary freedom fighter and peasant leader Swami Sahajanand Saraswati. Gaya has also immensely contributed in the Indian Independence Movement. During the independence movement, the All India session of the Congress was held under the presidency of Deshbandhu Chittaranjan Das in 1922, which was attended by great illumanaries and prominent leaders of the Indian Independence Movement, such as Mohandas K. Gandhi, Dr. Rajendra Prasad, Dr Anugrah Narayan Sinha, Sardar Patel, Maulana Azad, Jawaharlal Nehru and Sri Krishna Sinha. The former Bihar Chief Minister Late Satyendra Narain Sinha also hailed from Gaya. Shri Ishwar Chaudhary was a member of Fifth, Sixth and Ninth Lok Sabha during 1971-79 and 1989-91 representing Gaya constituency of Bihar.
ESTABLISHMENT OF THE GAYA DISTRICT
Gaya was established in the year 1865. Earlier Gaya was a part of the district of erstwhile Behar of Ramgarh (now in Jharkhand state) till 1864. It was given the status of independent district on 3 October 1865. Subsequently, in May 1981, Magadh division was created by the Bihar state government with the districts of Gaya, Nawada, Aurangabad and Jehanabad. All these district were at the level of sub-division, when the Gaya district was created. Gaya has seen three district partitioned off from its territory, Aurangabad and Nawada in 1976; and Jehanabad in 1988. Gaya district occupies an area of 4,976 km2 comparatively equivalent to the island of Trinidad.
CLIMATE
As Gaya is surrounded by hills from three sides and one side by rivers so the climate of Gaya is seasonable (means in winter it is too cold and in summer it is too hot). Climate is characterised by relatively high temperatures and evenly distributed precipitation throughout the year. The Köppen Climate Classification sub-type for this climate is "Cfa" (Humid Subtropical Climate).
ECONOMY
Gaya is the second biggest economy contributor after Patna for Bihar. It has a large number of household industries like production of agarbattis, production of tilkut and lai, stone crafting, power looms, Small Scale manufacturing industries, packing industries, plastic products industries, Scrap Industries and hand looms. Gaya functions as a service centre for the surrounding towns and villages. Commercial activities are located along the important roads of the town. The main vegetable market in the city is the Kedarnath Market. In additional the city has a large number of informal shops. On account of Gaya being an important centre for religious tourism, the city has a large number of costly and affordable Hotels and accommodations. Gaya has the highest number of hotels in Bihar & Jharkhand. One Five Star hotel is also proposed in Bodh gaya. Maha Bodhi Hotel, Resort, Convention Centre is the largest and most beautiful hotel in bodhgaya. On the other hand Sambodhi Retreat the best resort of Bihar and Jharkhand is also in the city.
Recently, Gaya has been chosen as one of the heritage cities for HRIDAY - Heritage City Development and Augmentation Yojana scheme of Government of India.

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 sulphur.
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.

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
It is easily crumbled to be added to a lit coal in an incense burner. There are a lot of other scents stored elsewhere.
The frankincense was of good quality.
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.
A variety of incense cones which thankfully were not overly sweet. I am sad to have likely lost this annual Toronto ON sconce of incense cones.

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.
