Jab qata ki masafat e shab aaftaab ne
Jalwa kiya sahar ke rukhe behijaab ne
Dekha suwe falaq Shahe gardoon raqaab ne
Mudh kar sada rafeeqo ko di us janaab ne
Aakhir hai raat hamd o sanaye Khuda karo
Utho fareezaye sahri ko ada karo
Haan ghaaziyon ye din hai jidaal o qitaal ka
Yaan khoon bahega aaj Mohammad ki aal ka
Chehra khushi se surkh hai Zahra ke laal ka
Guzri shabe firaaq din aaya visaal ka
Hum wo hain gham karenge malak jin ke waastey
Raatein tadap ke kaati hai is din ke waastey
Ye sunke bistaron se uthe wo Khuda shinaas
Ek ek ne zebe jism kiya fakhira libaas
Shane muhasino mein kiye sab ne be hiraas
Baandhe amame aaye imame zaman ke paas
Rangeen abaayein dosh pe kamre kasey huwe
Muskh o zibaad o itr mein kapde basey huwe
Khaime se nikle Shay ke azeezaane khush khisaal
Jin mein kayi thay Hazrate Khairun nisa ke laal
Qasim sa gul badan Ali Akbar sa khush jamaal
Ek jaa Aqeel o Muslim o Jafar ke nau nihaal
Sab ke rukhon ka noor sipahre bareen pa tha
Athara aaftaabon ka ghuncha zameen pa tha
Nagaah charkh par khate abyaz huwa ayaan
Tashreef jaanemaaz pe laaye Shahe zamaan
Sajjade bich gaye aqabe Shahe ins o jaan
Saute Hasan se Akbar e Mahrooh ne di azaan
Har ek ki chashm aansuon se dab daba gayi
Goya sada Rasool ki kaano mein aagayi
Namoose Shaah rotey thay khaime mein zaar zaar
Chupke khadi thi sahn mein bano e naamdaar
Zainab balayein leke ye kahti thi baar baar
Sadqe namaziyoon ke muazzin ke main nisaar
Karte hain yoon sana o sifat Zul Jalaal ki
Logon azaan suno meri yousuf jamaal ki
Ye husn e saut aur ye qirat ye shad o madd
Haqqa ke afsahul fusuha thay inhi ke jadd
Goya hai lahn e Hazrat e Dawoode ba khiradd
Ya Rabb rakh is sada ko zamane mein taa abadd
Shu'be sada mein pankhadiyaan jaise phool mein
Bul bul chahak raha hai riyaaz e Rasool mein
Saf mein huwa jo naraye qad qaamatis salaat
Qaim huwi namaaz uthey Shahe qainaat
Wo noor ki safein wo musalli falak sifaat
Sardaar ke qadam ke taley thi rahe nijaat
Jalwa tha ta ba arshe mu'alla Hussain ka
Mus haf ki lauh thi ke musalla Hussain ka
Quraan khula huwa ke jama'at ki thi namaaz
Bismillah aagey jaise ho yoon thay Shahe hijaaz
Satrein thi ya safein aqab e Shahe sarfaraaz
Karti thi khud namaaz bhi inki adaa pe naaz
Sadqe sahar bayaaz pe bainas sutoor ki
Sab aayatein thi mus hafe naatikh ki noor ki
Dunya se uth gaya wo qayaam aur wo qaood
Inke liye thi bandagi wajibul wujood
Wo ajz wo taweel ruku aur wo sujood
Ta'at mein neest jaantey thay apni hast o bood
Taqat na chalne phirne ki thi haath paon mein
Gir gir ke sajde karte thay taghoon ki chaon mein
Farigh huwe namaaz se jab qibla o anaam
Aaye musafahe ko jawaanan e tashnakaam
Chume kise ne dast e Shahinshaah e khaas o aam
Aakhein miley kisi ne qadam par ba ehteraam
Kya dil thay kya sipaah e rasheed o sayeed thi
Ba ham mu'anaqe thay ke marne ki eid thi
Zaari thi ilteja thi munajaat thi idhar
Waan sar kashi o zulm o ta'addi o shor o shar
Kahta tha ibne saad ye jaa jaa ke nahr par
Ghatoon se hoshiyaar tarayi se ba khabar
Do roz se hai tashna dahani Hussain ko
Haan martey dam bhi deejiyo na pani Hussain ko
Baithey thay jaanemaaz pe Shahe falak sareer
Nagaah qareeb aake girey teen chaar teer
Dekha har ek ne mudhke suwe lashkar e kaseer

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.
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.
It's about 5 inches wide and may have been manufactured in the 1950's.
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.
Karva Chauth is observed by married women (suhagini) for ensuring wedded bliss and wishing long life for their husbands and children. A married woman who observes this vrat is called ‘Saubhagyavati’ (joyous and happy state of wifehood).
On the occasion of this vrat (Fast) a kalash (small container) is filled with either milk or water. In that kalash is placed Pancha Ratna (five pieces of different metals gold, silver, copper, brass and iron). The kalash is then presented to a Brahmin and also exchanged with other married women. While thus presenting the kalash, a wishful prayer is offered to Lord Ganesh: "Let the offerings of this Karva (Karak (gift bring long life to my husband and may my saubhagya be everlasting". And express such desire that ‘May my death precede that of my husband so that I can enter the chitaa (funeral pyre) as a bride (not as a widow).
This katha (narrative) first took place between Siva and parvati. Siva told Parvati about the significance of Karva Vrat. In Dwapar Yuga, Draupadi asked Lord Krishna about the vrat of Karva Chauth. Thereafter, the very first time this vrat was observed in the town of Shukraprastha by Veeravati, the daughter of Vedsharma and Leelavati. Ever since this vrat has been observed by married women till the present day.
On the occasion of Karva Chauth which is on the day of Kartik Krishna Chaturthi, fasting (vrat) is observed. In the evening, after taking a bath, under a banyan tree (or in the absence of such tree, draw a picture of such tree) place murtis or pictures of Siva, Parvati, Ganesh and Kartikeya and do puja ceremony (shodashopachar or sixteen step puja ceremony). Then for the offerings of arghya (rice, flower etc.), while waiting for the moon to rise, japa is done with the mantra "Om namah Shivaya". Havan (sacred fire ceremony) is also done. Thereafter, having sited the moon, offer the arghya.
If the husband is present, then worship him with Panchopchar or gandh, pushpa, dhoop, deep and naivedya (perfume, flower, incence, lamp and food). If the husband is away on travels, then offer a prayer to Almighy to grant long life to your husband. Thereafter bring the vrat to its conclusion.
Lord Krishna urged Draupadi to observe the vrat of Karva Chauth so that through its influence Arjuna can defeat the Kauravas on the battlefield and acquire back the kingdom.
Married women who thus offer wishful prayer for saubhagya by observing the Karva Chauth Vrat, acquire saubhagya, progeny and lasting prosperity.
With every passing hour, Autumn comes near. For the large Bengali community around the world, it means only one thing. Their biggest festival, the Durga Puja, is drawing nearer and nearer. It is the time when the whole of Bengal pulsates with the unique philharmonic of conch shells, the rhythms of dhaks (drums), the "Ulu Dhani" (tongue sounds) of Bengali women, the burning of dhoop (incense), pushpanjalis (flower offerings) and of course, the chanting of hymns and prayers. Nature seems to join into the celebration with the sunny weather, clear blue sky and gentle breeze that blows time and again. The spirit of festivity breaks loose all over Bengal and wherever Bengalis have a presence.
Durga Puja is the biggest festival in Bengal. This is also known as Dussehra and Navaratri in other parts of India. Durga is the Goddess of divine power against all evils. The story goes that Mahisasur, the Buffalo Demon, through years of praying, received blessing from Lord Brahma, that no power can kill him which means he is invincible. But once gaining this power he started ravaging the whole world and killing people. And finally he wanted to uproot the Gods too. The Gods, in dismay, combined their powers to create a beautiful maiden, and each placed his or her most potent weapon in one of her ten hands riding a lion.
The tableau of Durga with her four children - Kartik, Ganesh, Saraswati and Lakshmi, representing respectively the Protector, the Initiator of the puja, Knowledge and the Provider - signifies the complete manifestation of the goddess.
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.

The term Bijoya , literally means Victory and Shubho Bijoya means "The Auspicious Victory". Shubo Bijoya is celebrated from the last day of Durga Puja, i.e., Vijaya Dashami to Kali Puja (Diwali). It is celebrated for about a period of one month.When Maa Durga destroyed the demon Mahishasur in a ten daylong battle, the day was christened as Vijaya Dashami - the day of victory. This victory is a celebration of good and end of evil era. Shubho Bijoya is not just a traditional greeting, but also a way to celebrate the auspicious victory over evil...

A round Chinese incense burner that burns coiled incense behind a ceramic mermaid on a Chinese base.
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.

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
From Chapter 5 of the Shri Sai Satcharita:
~~~~~
There lived in the Aurangabad District (Nizam State), in a village called Dhoop, a well-to-do Mahomedan gentleman by name Chand Patil. While he was making a trip to Aurangabad, he lost his mare. For two long months, he made a diligent search but could get no trace of the lost mare. After being disappointed, he returned from Aurangabad with the saddle on his back. After travelling four Koss and a half, he came, on the way, to a mango tree under the foot of which sat a RATNA (queer fellow). He had a cap on His head, wore Kafni (long robe) and had a "Satka" (short stick) under His arm-pit and He was preparing to smoke a Chilim (pipe). On seeing Chand Patil pass by the way, He called out to him and asked him to have a smoke and to rest a little. The Fakir asked him about the saddle. Chand Patil replied that it was of his mare which was lost. The queer fellow or Fakir asked him to make a search in the Nala close by. He went and the wonder of wonders! he found out the mare. He thought that this Fakir was not an ordinary man, but an Avalia (a great saint).

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.

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.

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.

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.

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.

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.

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.

HISTORY:
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.
The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.
Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.
At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.
Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.
COMPOSITION:
A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.
Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.
COMBUSTIBLE BASE:
The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:
Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.
Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:
Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii) Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.
Jigit: a resin based binder used in India
Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.
Typical compositions burn at a temperature between 220 °C and 260 °C.
TYPES:
Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.
INDIRECT-BURNING:
Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.
Whole: The incense material is burned directly in raw form on top of coal embers.
Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odour.
Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.
DIRECT-BURNING:
Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.
Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.
Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.
Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".
Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.
Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.
Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.
Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.
Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.
Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.
PRODUCTION:
The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.
Certain proportions are necessary for direct-burning incense:
Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.
Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.
Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.
Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.
Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.
"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE:
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.
CULTURAL VARIATIONS:
ARABIAN:
In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.
CHINESE:
For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.
Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,
Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.
Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.
Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.
INDIAN:
Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.
The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.
JEWISH TEMPLE IN JERUSALEM:
KETORET:
Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.
TIBETAN:
Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.
Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.
JAPANESE:
In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.
Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.
Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.
Some terms used in Japanese incense culture include:
Incense arts: [香道, kodo]
Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.
Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning
Charcoal: [木炭] – only the odorless kind is used.
Incense woods: [ 香木 ] – a naturally fragrant resinous wood.
USAGE:
PRACTICAL:
Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.
A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.
The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.
Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.
Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.
Incense is also used often by people who smoke indoors and do not want the smell to linger.
AESTHETIC:
Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS:
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE:
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.
Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.
Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.
Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.
The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.
Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.
At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.
Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.
COMPOSITION
A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.
Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.
COMBUSTIBLE BASE
The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:
Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.
Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:
Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)
Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.
Jigit: a resin based binder used in India
Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.
Typical compositions burn at a temperature between 220 °C and 260 °C.
TYPES
Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.
INDIRECT-BURNING
Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.
Whole: The incense material is burned directly in raw form on top of coal embers.
Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.
Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.
DIRECT-BURNING
Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.
Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.
Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.
Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".
Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.
Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.
Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.
Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.
Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.
Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.
PRODUCTION
The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.
Certain proportions are necessary for direct-burning incense:
Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.
Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.
Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.
Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.
Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.
"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.
CULTURAL VARIATIONS
ARABIAN
In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.
CHINESE
For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.
Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,
Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.
Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.
Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.
INDIAN
Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.
The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.
JEWISH TEMPLE IN JERUSALEM
KETORET
Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.
TIBETAN
Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.
Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.
JAPANESE
In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.
Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.
Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.
Some terms used in Japanese incense culture include:
Incense arts: [香道, kodo]
Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.
Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning
Charcoal: [木炭] – only the odorless kind is used.
Incense woods: [ 香木 ] – a naturally fragrant resinous wood.
USAGE
PRACTICAL
Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.
A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.
The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.
Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.
Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.
Incense is also used often by people who smoke indoors and do not want the smell to linger.
AESTHETIC
Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.
WIKIPEDIA
Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.
Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.
Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma.

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 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.

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.

"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE:
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.
CULTURAL VARIATIONS:
ARABIAN:
In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.
CHINESE:
For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.
Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,
Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.
Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.
Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.
INDIAN:
Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.
The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.
JEWISH TEMPLE IN JERUSALEM:
KETORET:
Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.
TIBETAN:
Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.
Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.
JAPANESE:
In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.
Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.
Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.
Some terms used in Japanese incense culture include:
Incense arts: [香道, kodo]
Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.
Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning
Charcoal: [木炭] – only the odorless kind is used.
Incense woods: [ 香木 ] – a naturally fragrant resinous wood.
USAGE:
PRACTICAL:
Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.
A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.
The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.
Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.
Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.
Incense is also used often by people who smoke indoors and do not want the smell to linger.
AESTHETIC:
Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS:
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE:
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

From Wikipedia -
Frankincense, also called olibanum (Arabic: لُبَّانٌ, lubbān; Chinese: 乳香 Ru Xiang; Somali: luubaan; Hindi: धुप Dhoop; Hebrew: לבונה, levonah), is an aromatic resin obtained from trees of the genus Boswellia, particularly Boswellia sacra, B. carteri, B. thurifera, B. frereana and B. bhaw-dajiana (Burseraceae). The English word is derived from old French "franc encens" (i.e. high quality incense) and is used in incense and perfumes.
There are four main species of Boswellia that produce true frankincense and resin from each of the four is available in various grades. The grades depend on the time of harvesting. The resin is hand-sorted for quality.
Frankincense can also be found in the Bible as one of the three gifts the wise men gave to baby Jesus.
Frankincense is tapped from the scraggly but hardy trees by slashing the bark, which is called striping, and allowing the exuded resin to bleed out and harden. These hardened resins are called tears. The aroma from these tears are more valuable for their presumed healing abilities and are also said to have superior qualities for religious ritual.
There are several species and varieties of frankincense trees, each producing a slightly different type of resin. Differences in soil and climate create even more diversity of the resin, even within the same species. Boswellia Sacra trees are considered unusual for their ability to grow in environments so unforgiving that they sometimes grow out of solid rock. The initial means of attachment to the rock is unknown but is accomplished by a bulbous disk-like swelling of the trunk. This growth prevents it from being ripped from the rock during violent storms that frequent this region. This feature is slight or absent in trees grown in rocky soil or gravel. The trees start producing resin when they are about eight to 10 years old. Tapping is done two to three times a year with the final taps producing the best tears due to their higher aromatic terpene, sesquiterpene and diterpene content. Generally speaking, the more opaque resins are the best quality. Fine resin is produced in Yemen and along the northern coast of Somalia, from which the Roman Catholic Church draws its supplies.
Recent studies have indicated that frankincense tree populations are declining, partly due to over-exploitation. Heavily tapped trees produce seeds that germinate at only 16% while seeds of trees that had not been tapped germinate at more than 80%. In addition, burning, grazing, and attacks by the longhorn beetle have reduced the tree population. Conversion (clearing) of frankincense woodlands to agriculture is also a major threat.
Frankincense is used in perfumery and aromatherapy. It is also an ingredient that is sometimes used in skincare. The essential oil is obtained by steam distillation of the dry resin. Some of the smell of the frankincense smoke are products of pyrolysis.
Frankincense is used in many Christian churches including the Eastern Orthodox, Oriental Orthodox and Catholic churches. According to the gospel of Matthew 2:11, gold, frankincense, and myrrh were among the gifts to Jesus by the biblical magi "from out of the East." The Judaic, Christian and Islamic faiths have all used frankincense mixed with oils to anoint newborn infants, initiates, and members entering into new phases of their spiritual lives.
Conversely, the growth of Christianity depressed the market for frankincense during the 4th century AD. Desertification made the caravan routes across the Rub' al Khali or "Empty Quarter" of the Arabian Peninsula more difficult. Additionally, increased raiding by the nomadic Parthians in the Near East caused the frankincense trade to dry up after A.D. 300.
Traditional medicine[edit]
Frankincense resin is edible and is used in traditional medicines in Asia for digestion and healthy skin. For internal consumption, it is recommended that frankincense be translucent, with no black or brown impurities. It is often light yellow with a (very) slight greenish tint. It is often chewed like gum, but it is stickier.
In Ayurvedic medicine Indian frankincense (Boswellia serrata), commonly referred to as "dhoop," has been used for hundreds of years for treating arthritis, healing wounds, strengthening the female hormone system and purifying the air. The use of frankincense in Ayurveda is called "dhoopan". In Indian culture, it is suggested that burning frankincense daily in the house brings good health.
The essential oil of frankincense is produced by steam distillation of the tree resin. The oil's chemical components are 75% monoterpenes, sesquiterpenes, monoterpenoles, sesquiterpenols, and ketones. It has a good balsamic sweet fragrance, while the Indian frankincense oil has a very fresh smell. Contrary to recent claims, steam or hydro distilled frankincense oil does not contain any boswellic acid as these components (triterpenoids) are non-volatile and too large to come over in the steam distillation process. The chemistry of the essential oil is mainly monoterpenes and sesquiterpenes with small amounts of diterpenoid components being the upper limit in terms of molecular weight.
Olibanum is characterized by a balsamic-spicy, slightly lemon, fragrance of incense, with a conifer-like undertone. It is used in the perfume, cosmetic and pharmaceutical industries.
These are some of the chemical compounds present in frankincense -
"acid resin (56%), soluble in alcohol and having the formula C20H32O4"
gum (similar to gum arabic) 30–36%
3-acetyl-beta-boswellic acid (Boswellia sacra)
alpha-boswellic acid (Boswellia sacra)
4-O-methyl-glucuronic acid (Boswellia sacra)
incensole acetate
phellandrene
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.

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad.

For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks.

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.

Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.
The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.
Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.
At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.
Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.
COMPOSITION
A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.
Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.
COMBUSTIBLE BASE
The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:
Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.
Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:
Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)
Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.
Jigit: a resin based binder used in India
Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.
Typical compositions burn at a temperature between 220 °C and 260 °C.
TYPES
Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.
INDIRECT-BURNING
Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.
Whole: The incense material is burned directly in raw form on top of coal embers.
Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.
Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.
DIRECT-BURNING
Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.
Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.
Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.
Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".
Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.
Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.
Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.
Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.
Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.
Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.
PRODUCTION
The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.
Certain proportions are necessary for direct-burning incense:
Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.
Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.
Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.
Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.
Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.
"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.
CULTURAL VARIATIONS
ARABIAN
In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.
CHINESE
For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.
Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,
Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.
Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.
Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.
INDIAN
Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.
The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.
JEWISH TEMPLE IN JERUSALEM
KETORET
Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.
TIBETAN
Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.
Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.
JAPANESE
In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.
Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.
Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.
Some terms used in Japanese incense culture include:
Incense arts: [香道, kodo]
Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.
Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning
Charcoal: [木炭] – only the odorless kind is used.
Incense woods: [ 香木 ] – a naturally fragrant resinous wood.
USAGE
PRACTICAL
Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.
A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.
The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.
Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.
Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.
Incense is also used often by people who smoke indoors and do not want the smell to linger.
AESTHETIC
Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.
WIKIPEDIA
Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.
Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.
Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.
The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.
Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.
At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.
Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.
COMPOSITION
A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.
Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.
COMBUSTIBLE BASE
The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:
Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.
Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:
Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)
Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.
Jigit: a resin based binder used in India
Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.
Typical compositions burn at a temperature between 220 °C and 260 °C.
TYPES
Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.
INDIRECT-BURNING
Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.
Whole: The incense material is burned directly in raw form on top of coal embers.
Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.
Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.
DIRECT-BURNING
Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.
Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.
Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.
Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".
Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.
Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.
Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.
Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.
Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.
Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.
PRODUCTION
The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.
Certain proportions are necessary for direct-burning incense:
Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.
Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.
Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.
Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.
Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.
"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.
CULTURAL VARIATIONS
ARABIAN
In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.
CHINESE
For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.
Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,
Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.
Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.
Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.
INDIAN
Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.
The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.
JEWISH TEMPLE IN JERUSALEM
KETORET
Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.
TIBETAN
Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.
Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.
JAPANESE
In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.
Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.
Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.
Some terms used in Japanese incense culture include:
Incense arts: [香道, kodo]
Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.
Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning
Charcoal: [木炭] – only the odorless kind is used.
Incense woods: [ 香木 ] – a naturally fragrant resinous wood.
USAGE
PRACTICAL
Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.
A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.
The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.
Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.
Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.
Incense is also used often by people who smoke indoors and do not want the smell to linger.
AESTHETIC
Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.
WIKIPEDIA
Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.
Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.
Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.
The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.
Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.
At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.
Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.
COMPOSITION
A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.
Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.
COMBUSTIBLE BASE
The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:
Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.
Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:
Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)
Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.
Jigit: a resin based binder used in India
Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.
Typical compositions burn at a temperature between 220 °C and 260 °C.
TYPES
Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.
INDIRECT-BURNING
Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.
Whole: The incense material is burned directly in raw form on top of coal embers.
Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.
Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.
DIRECT-BURNING
Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.
Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.
Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.
Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".
Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.
Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.
Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.
Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.
Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.
Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.
PRODUCTION
The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.
Certain proportions are necessary for direct-burning incense:
Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.
Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.
Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.
Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.
Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.
"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.
CULTURAL VARIATIONS
ARABIAN
In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.
CHINESE
For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.
Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,
Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.
Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.
Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.
INDIAN
Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.
The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.
JEWISH TEMPLE IN JERUSALEM
KETORET
Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.
TIBETAN
Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.
Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.
JAPANESE
In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.
Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.
Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.
Some terms used in Japanese incense culture include:
Incense arts: [香道, kodo]
Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.
Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning
Charcoal: [木炭] – only the odorless kind is used.
Incense woods: [ 香木 ] – a naturally fragrant resinous wood.
USAGE
PRACTICAL
Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.
A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.
The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.
Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.
Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.
Incense is also used often by people who smoke indoors and do not want the smell to linger.
AESTHETIC
Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.
WIKIPEDIA
Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.
Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.
Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.
The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.
Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.
At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.
Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.
COMPOSITION
A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.
Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.
COMBUSTIBLE BASE
The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:
Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.
Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:
Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)
Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.
Jigit: a resin based binder used in India
Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.
Typical compositions burn at a temperature between 220 °C and 260 °C.
TYPES
Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.
INDIRECT-BURNING
Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.
Whole: The incense material is burned directly in raw form on top of coal embers.
Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.
Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.
DIRECT-BURNING
Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.
Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.
Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.
Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".
Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.
Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.
Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.
Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.
Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.
Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.
PRODUCTION
The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.
Certain proportions are necessary for direct-burning incense:
Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.
Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.
Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.
Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.
Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.
"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.

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.

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.

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 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.

Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.
WIKIPEDIA
An art deco incense burner, likely mass marketed in the 1930's from the U.S.A. The basket top lifts to allow one or more incense cones. It was sold for a song when compared to similar Art Deco female metal incense burners listed on EBay.
Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.
Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.
Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.
The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.
Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.
At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.
Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.
COMPOSITION
A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.
Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.
COMBUSTIBLE BASE
The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:
Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.
Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:
Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)
Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.
Jigit: a resin based binder used in India
Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.
Typical compositions burn at a temperature between 220 °C and 260 °C.
TYPES
Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.
INDIRECT-BURNING
Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.
Whole: The incense material is burned directly in raw form on top of coal embers.
Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.
Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.
DIRECT-BURNING
Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.
Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.
Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.
Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".
Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.
Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.
Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.
Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.
Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.
Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.
PRODUCTION
The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.
Certain proportions are necessary for direct-burning incense:
Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.
Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.
Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.
Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.
Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.
"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.
CULTURAL VARIATIONS
ARABIAN
In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.
CHINESE
For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.
Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,
Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.
Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.
Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.
INDIAN
Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.
The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.
JEWISH TEMPLE IN JERUSALEM
KETORET
Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.
TIBETAN
Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.
Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.
JAPANESE
In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.
Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.
Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.
Some terms used in Japanese incense culture include:
Incense arts: [香道, kodo]
Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.
Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning
Charcoal: [木炭] – only the odorless kind is used.
Incense woods: [ 香木 ] – a naturally fragrant resinous wood.
USAGE
PRACTICAL
Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.
A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.
The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.
Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.
Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.
Incense is also used often by people who smoke indoors and do not want the smell to linger.
AESTHETIC
Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY:
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. 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.

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.

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.

In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad.

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

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.

Agarbathi :
India has a rich tradition of incense making that goes back millennia. Many Indian incenses have a unique scent that is not found in any other part of the globe. Incense sticks formed around bamboo are known as agarbatti or agarbathi, while other main forms of incense are cones and logs or dhoops, which are incense paste formed into pyramid shapes or log shapes, and then dried. Thus, modern, organized incense-making is intrinsically linked to the Ayurvedic medical system in which it is rooted.
Oil Lamp or Kuthu Vilakku
The lamp has its own special place. It is a form and a symbol of Tej (Absolute fire principle); the lamp leads us from darkness towards light. It burns only to give message of peace and light to the human. This is its greatness. Agni Puran clearly states that only oil or Ghee (clarified butter) be used in the lamp meant for puja and no other combustible substance. According to the Science of spirituality the lamp with clarified butter is more sattvik (spiritually pure) as compared to lamp in which oil is used. According to yogic path of Kundalini Yog there are seven principle chakras or energy centers in the human being. These chakras influence practically every aspect of human being including physical body, mind and intellect.

Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.
Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.
Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.
The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.
Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.
At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.
Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.
COMPOSITION
A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.
Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.
COMBUSTIBLE BASE
The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:
Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.
Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:
Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)
Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.
Jigit: a resin based binder used in India
Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.
Typical compositions burn at a temperature between 220 °C and 260 °C.
TYPES
Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.
INDIRECT-BURNING
Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.
Whole: The incense material is burned directly in raw form on top of coal embers.
Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.
Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.
DIRECT-BURNING
Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.
Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.
Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.
Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".
Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.
Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.
Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.
Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.
Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.
Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.
PRODUCTION
The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.
Certain proportions are necessary for direct-burning incense:
Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.
Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.
Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.
Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.
Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.
"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.
CULTURAL VARIATIONS
ARABIAN
In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.
CHINESE
For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.
Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,
Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.
Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.
Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.
INDIAN
Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.
The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.
JEWISH TEMPLE IN JERUSALEM
KETORET
Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.
TIBETAN
Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.
Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.
JAPANESE
In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.
Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.
Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.
Some terms used in Japanese incense culture include:
Incense arts: [香道, kodo]
Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.
Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning
Charcoal: [木炭] – only the odorless kind is used.
Incense woods: [ 香木 ] – a naturally fragrant resinous wood.
USAGE
PRACTICAL
Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.
A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.
The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.
Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.
Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.
Incense is also used often by people who smoke indoors and do not want the smell to linger.
AESTHETIC
Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.

Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.
The Babylonians used incense while offering prayers to divining oracles. Incense spread from there to Greece and Rome.
Incense burners have been found in the Indus Civilization (3300–1300 BCE). Evidence suggests oils were used mainly for their aroma. India also adopted techniques from East Asia, adapting the formulation to encompass aromatic roots and other indigenous flora. This was the first usage of subterranean plant parts in incense. New herbs like Sarsaparilla seeds, frankincense, and cypress were used by Indians.
At around 2000 BCE, Ancient China began the use of incense in the religious sense, namely for worship. Incense was used by Chinese cultures from Neolithic times and became more widespread in the Xia, Shang, and Zhou dynasties. The earliest documented use of incense comes from the ancient Chinese, who employed incense composed of herbs and plant products (such as cassia, cinnamon, styrax, and sandalwood) as a component of numerous formalized ceremonial rites. Incense usage reached its peak during the Song dynasty with numerous buildings erected specifically for incense ceremonies.
Brought to Japan in the 6th century by Korean Buddhist monks, who used the mystical aromas in their purification rites, the delicate scents of Koh (high-quality Japanese incense) became a source of amusement and entertainment with nobles in the Imperial Court during the Heian Era 200 years later. During the 14th-century Ashikaga shogunate, a samurai warrior might perfume his helmet and armor with incense to achieve an aura of invincibility (as well as to make a noble gesture to whoever might take his head in battle). It wasn't until the Muromachi period during the 15th and 16th century that incense appreciation (kōdō) spread to the upper and middle classes of Japanese society.
COMPOSITION
A variety of materials have been used in making incense. Historically there has been a preference for using locally available ingredients. For example, sage and cedar were used by the indigenous peoples of North America. Trading in incense materials comprised a major part of commerce along the Silk Road and other trade routes, one notably called the Incense Route.
Local knowledge and tools were extremely influential on the style, but methods were also influenced by migrations of foreigners, such as clergy and physicians.
COMBUSTIBLE BASE
The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:
Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.
Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:
Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)
Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.
Jigit: a resin based binder used in India
Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.
Typical compositions burn at a temperature between 220 °C and 260 °C.
TYPES
Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.
INDIRECT-BURNING
Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.
Whole: The incense material is burned directly in raw form on top of coal embers.
Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odor.
Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.
DIRECT-BURNING
Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.
Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.
Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.
Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".
Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.
Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.
Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.
Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.
Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.
Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.
PRODUCTION
The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.
Certain proportions are necessary for direct-burning incense:
Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.
Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.
Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.
Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.
Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.
"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimeters.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.
CULTURAL VARIATIONS
ARABIAN
In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.
CHINESE
For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.
Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,
Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.
Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.
Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.
INDIAN
Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.
The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.
JEWISH TEMPLE IN JERUSALEM
KETORET
Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.
TIBETAN
Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.
Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.
JAPANESE
In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.
Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.
Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.
Some terms used in Japanese incense culture include:
Incense arts: [香道, kodo]
Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.
Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning
Charcoal: [木炭] – only the odorless kind is used.
Incense woods: [ 香木 ] – a naturally fragrant resinous wood.
USAGE
PRACTICAL
Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.
A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.
The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.
Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.
Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.
Incense is also used often by people who smoke indoors and do not want the smell to linger.
AESTHETIC
Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
Incensole acetate, a component of Frankincense, has been shown to have anxiolytic-like and antidepressive-like effects in mice, mediated by activation of poorly-understood TRPV3 ion channels in the brain.
WIKIPEDIA
An Art Nouveau Incense Burner.
Incense is aromatic biotic material that releases fragrant smoke when burned. The term refers to the material itself, rather than to the aroma that it produces. Incense is used for aesthetic reasons, and in therapy, meditation, and ceremony. It may also be used as a simple deodorant or insectifuge.
Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.
Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stick, or a paste that is extruded into a stick or cone shape.
HISTORY:
The word incense comes from Latin incendere meaning "to burn".
Combustible bouquets were used by the ancient Egyptians, who employed incense in both pragmatic and mystical capacities. Incense was burnt to counteract or obscure malodorous products of human habitation, but was widely perceived to also deter malevolent demons and appease the gods with its pleasant aroma. Resin balls were found in many prehistoric Egyptian tombs in El Mahasna, giving evidence for the prominence of incense and related compounds in Egyptian antiquity. One of the oldest extant incense burners originates from the 5th dynasty. The Temple of Deir-el-Bahari in Egypt contains a series of carvings that depict an expedition for incense.

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.

COMBUSTIBLE BASE:
The combustible base of a direct burning incense mixture not only binds the fragrant material together but also allows the produced incense to burn with a self-sustained ember, which propagates slowly and evenly through an entire piece of incense with such regularity that it can be used to mark time. The base is chosen such that it does not produce a perceptible smell. Commercially, two types of incense base predominate:
Fuel and oxidizer mixtures: Charcoal or wood powder provides the fuel for combustion while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials are added to the base prior to shaping, as in the case of powdered incense materials, or after, as in the case of essential oils. The formula for charcoal-based incense is superficially similar to black powder, though it lacks the sulfur.
Natural plant-based binders: Gums such as Gum Arabic or Gum Tragacanth are used to bind the mixture together. Mucilaginous material, which can be derived from many botanical sources, is mixed with fragrant materials and water. The mucilage from the wet binding powder holds the fragrant material together while the cellulose in the powder combusts to form a stable ember when lit. The dry binding powder usually comprises about 10% of the dry weight in the finished incense. These include:
Makko (incense powder) made from the bark of various trees in the genus Persea (such as Persea thunbergii)
Xiangnan pi (made from the bark of trees of genus Phoebe such as Phoebe nanmu or Persea zuihoensis.
Jigit: a resin based binder used in India
Laha or Dar: bark based powders used in Nepal, Tibet, and other East Asian countries.
Typical compositions burn at a temperature between 220 °C and 260 °C.
TYPES:
Incense is available in various forms and degrees of processing. They can generally be separated into "direct-burning" and "indirect-burning" types. Preference for one form or another varies with culture, tradition, and personal taste. The two differ in their composition due to the former's requirement for even, stable, and sustained burning.
INDIRECT-BURNING:
Indirect-burning incense, also called "non-combustible incense", is an aromatic material or combination of materials, such as resins, that does not contain combustible material and so requires a separate heat source. Finer forms tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually, having less surface area. Heat is traditionally provided by charcoal or glowing embers. In the West, the best known incense materials of this type are the resins frankincense and myrrh, likely due to their numerous mentions in the Bible. Frankincense means "pure incense", though in common usage refers specifically to the resin of the boswellia tree.
Whole: The incense material is burned directly in raw form on top of coal embers.
Powdered or granulated: Incense broken into smaller pieces burns quickly and provides brief but intense odour.
Paste: Powdered or granulated incense material is mixed with a sticky incombustible binder, such as dried fruit, honey, or a soft resin and then formed to balls or small pastilles. These may then be allowed to mature in a controlled environment where the fragrances can commingle and unite. Much Arabian incense, also called "Bukhoor" or "Bakhoor", is of this type, and Japan has a history of kneaded incense, called nerikō or awasekō, made using this method. Within the Eastern Orthodox Christian tradition, raw frankincense is ground into a fine powder and then mixed with various sweet-smelling essential oils.
DIRECT-BURNING:
Direct-burning incense, also called "combustible incense", is lit directly by a flame. The glowing ember on the incense will continue to smoulder and burn the rest of the incense without further application of external heat or flame. Direct-burning incense is either extruded, pressed into forms, or coated onto a supporting material. This class of incense is made from a moldable substrate of fragrant finely ground (or liquid) incense materials and odourless binder. The composition must be adjusted to provide fragrance in the proper concentration and to ensure even burning. The following types are commonly encountered, though direct-burning incense can take nearly any form, whether for expedience or whimsy.
Coil: Extruded and shaped into a coil without a core, coil incense can burn for an extended period, from hours to days, and is commonly produced and used in Chinese cultures.
Cone: Incense in this form burns relatively quickly. Incense cones were invented in Japan in the 1800s.
Cored stick: A supporting core of bamboo is coated with a thick layer of incense material that burns away with the core. Higher-quality variations have fragrant sandalwood cores. This type of incense is commonly produced in India and China. When used in Chinese folk religion, these are sometimes known as "joss sticks".
Dhoop or solid stick: With no bamboo core, dhoop incense is easily broken for portion control. This is the most commonly produced form of incense in Japan and Tibet.
Powder: The loose incense powder used for making indirect burning incense is sometimes burned without further processing. Powder incense is typically packed into long trails on top of wood ash using a stencil and burned in special censers or incense clocks.
Paper: Paper infused with incense, folded accordion style, is lit and blown out. Examples include Carta d'Armenia and Papier d'Arménie.
Rope: The incense powder is rolled into paper sheets, which are then rolled into ropes, twisted tightly, then doubled over and twisted again, yielding a two-strand rope. The larger end is the bight, and may be stood vertically, in a shallow dish of sand or pebbles. The smaller (pointed) end is lit. This type of incense is easily transported and stays fresh for extremely long periods. It has been used for centuries in Tibet and Nepal.
Moxa tablets, which are disks of powdered mugwort used in Traditional Chinese medicine for moxibustion, are not incenses; the treatment is by heat rather than fragrance.
Incense sticks may be termed joss sticks, especially in parts of East Asia, South Asia and Southeast Asia. Among ethnic Chinese and Chinese-influenced communities these are traditionally burned at temples, before the threshold of a home or business, before an image of a religious divinity or local spirit, or in shrines, large and small, found at the main entrance of every village. Here the earth god is propitiated in the hope of bringing wealth and health to the village. They can also be burned in front of a door or open window as an offering to heaven, or the devas. The word "joss" is derived from the Latin deus (god) via the Portuguese deos through the Javanese dejos, through Chinese pidgin English.
PRODUCTION:
The raw materials are powdered and then mixed together with a binder to form a paste, which, for direct burning incense, is then cut and dried into pellets. Incense of the Athonite Orthodox Christian tradition is made by powdering frankincense or fir resin, mixing it with essential oils. Floral fragrances are the most common, but citrus such as lemon is not uncommon. The incense mixture is then rolled out into a slab approximately 1 cm thick and left until the slab has firmed. It is then cut into small cubes, coated with clay powder to prevent adhesion, and allowed to fully harden and dry. In Greece this rolled incense resin is called 'Moskolibano', and generally comes in either a pink or green colour denoting the fragrance, with pink being rose and green being jasmine.
Certain proportions are necessary for direct-burning incense:
Oil content: an excess of oils may prevent incense from smoldering effectively. Resinous materials such as myrrh and frankincense are typically balanced with "dry" materials such as wood, bark and leaf powders.
Oxidizer quantity: Too little oxidizer in gum-bound incense may prevent the incense from igniting, while too much will cause the incense to burn too quickly, without producing fragrant smoke.
Binder: Water-soluble binders such as "makko" ensure that the incense mixture does not crumble when dry, dilute the mixture.
Mixture density: Incense mixtures made with natural binders must not be combined with too much water in mixing, or over-compressed while being formed, which would result in either uneven air distribution or undesirable density in the mixture, causing the incense to burn unevenly, too slowly, or too quickly.
Particulate size: The incense mixture has to be well pulverized with similarly sized particulates. Uneven and large particulates result in uneven burning and inconsistent aroma production when burned.
"Dipped" or "hand-dipped" direct-burning incense is created by dipping "incense blanks" made of unscented combustible dust into any suitable kind of essential or fragrance oil. These are often sold in the United States by flea-market and sidewalk vendors who have developed their own styles. This form of incense requires the least skill and equipment to manufacture, since the blanks are pre-formed in China or South East Asia.
Incense mixtures can be extruded or pressed into shapes. Small quantities of water are combined with the fragrance and incense base mixture and kneaded into a hard dough. The incense dough is then pressed into shaped forms to create cone and smaller coiled incense, or forced through a hydraulic press for solid stick incense. The formed incense is then trimmed and slowly dried. Incense produced in this fashion has a tendency to warp or become misshapen when improperly dried, and as such must be placed in climate-controlled rooms and rotated several times through the drying process.
Traditionally, the bamboo core of cored stick incense is prepared by hand from Phyllostachys heterocycla cv. pubescens since this species produces thick wood and easily burns to ashes in the incense stick. In a process known as "splitting the foot of the incense stick", the bamboo is trimmed to length, soaked, peeled, and split in halves until the thin sticks of bamboo have square cross sections of less than 3mm. This process has been largely replaced by machines in modern incense production.
In the case of cored incensed sticks, several methods are employed to coat the sticks cores with incense mixture:
Paste rolling: A wet, malleable paste of incense mixture is first rolled into a long, thin coil, using a paddle. Then, a thin stick is put next to the coil and the stick and paste are rolled together until the stick is centered in the mixture and the desired thickness is achieved. The stick is then cut to the desired length and dried.
Powder-coating: Powder-coating is used mainly to produce cored incense of either larger coil (up to 1 meter in diameter) or cored stick forms. A bundle of the supporting material (typically thin bamboo or sandalwood slivers) is soaked in water or a thin water/glue mixture for a short time. The thin sticks are evenly separated, then dipped into a tray of incense powder consisting of fragrance materials and occasionally a plant-based binder. The dry incense powder is then tossed and piled over the sticks while they are spread apart. The sticks are then gently rolled and packed to maintain roundness while more incense powder is repeatedly tossed onto the sticks. Three to four layers of powder are coated onto the sticks, forming a 2 mm thick layer of incense material on the stick. The coated incense is then allowed to dry in open air. Additional coatings of incense mixture can be applied after each period of successive drying. Incense sticks produced in this fashion and burned in temples of Chinese folk religion can have a thickness between 2 and 4 millimetres.
Compression: A damp powder is mechanically formed around a cored stick by compression, similar to the way uncored sticks are formed. This form is becoming more common due to the higher labor cost of producing powder-coated or paste-rolled sticks.
BURNING INCENSE:
Indirect-burning incense burned directly on top of a heat source or on a hot metal plate in a censer or thurible.
In Japan a similar censer called a egōro (柄香炉) is used by several Buddhist sects. The egōro is usually made of brass, with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as sonae-kō (religious burning).
For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. The flame is then fanned or blown out, leaving the incense to smolder.
CULTURAL VARIATIONS:
ARABIAN:
In most Arab countries, incense is burned in the form of scented chips or blocks called bakhoor (Arabic: بخور [bɑˈxuːɾ, bʊ-]. Incense is used on special occasions like weddings or on Fridays or generally to perfume the house. The bakhoor is usually burned in a mabkhara, a traditional incense burner (censer) similar to the Somali Dabqaad. It is customary in many Arab countries to pass bakhoor among the guests in the majlis ('congregation'). This is done as a gesture of hospitality.
CHINESE:
For over two thousand years, the Chinese have used incense in religious ceremonies, ancestor veneration, Traditional Chinese medicine, and daily life. Agarwood (chénxiāng) and sandalwood (tánxiāng) are the two most important ingredients in Chinese incense.
Along with the introduction of Buddhism in China came calibrated incense sticks and incense clocks. The first known record is by poet Yu Jianwu (487-551): "By burning incense we know the o'clock of the night, With graduated candles we confirm the tally of the watches." The use of these incense timekeeping devices spread from Buddhist monasteries into Chinese secular society.
Incense-stick burning is an everyday practice in traditional Chinese religion. There are many different types of stick used for different purposes or on different festive days. Many of them are long and thin. Sticks are mostly coloured yellow, red, or more rarely, black. Thick sticks are used for special ceremonies, such as funerals. Spiral incense, with exceedingly long burn times, is often hung from temple ceilings. In some states, such as Taiwan,
Singapore, or Malaysia, where they celebrate the Ghost Festival, large, pillar-like dragon incense sticks are sometimes used. These generate so much smoke and heat that they are only burned outside.
Chinese incense sticks for use in popular religion are generally odorless or only use the slightest trace of jasmine or rose, since it is the smoke, not the scent, which is important in conveying the prayers of the faithful to heaven. They are composed of the dried powdered bark of a non-scented species of cinnamon native to Cambodia, Cinnamomum cambodianum. Inexpensive packs of 300 are often found for sale in Chinese supermarkets. Though they contain no sandalwood, they often include the Chinese character for sandalwood on the label, as a generic term for incense.
Highly scented Chinese incense sticks are used by some Buddhists. These are often quite expensive due to the use of large amounts of sandalwood, agarwood, or floral scents used. The sandalwood used in Chinese incenses does not come from India, its native home, but rather from groves planted within Chinese territory. Sites belonging to Tzu Chi, Chung Tai Shan, Dharma Drum Mountain, Xingtian Temple, or City of Ten Thousand Buddhas do not use incense.
INDIAN:
Incense sticks, also known as agarbathi (or agarbatti) and joss sticks, in which an incense paste is rolled or moulded around a bamboo stick, are the main forms of incense in India. The bamboo method originated in India, and is distinct from the Nepali/Tibetan and Japanese methods of stick making without bamboo cores. Though the method is also used in the west, it is strongly associated with India.
The basic ingredients are the bamboo stick, the paste (generally made of charcoal dust and joss/jiggit/gum/tabu powder – an adhesive made from the bark of litsea glutinosa and other trees), and the perfume ingredients - which would be a masala (spice mix) powder of ground ingredients into which the stick would be rolled, or a perfume liquid sometimes consisting of synthetic ingredients into which the stick would be dipped. Perfume is sometimes sprayed on the coated sticks. Stick machines are sometimes used, which coat the stick with paste and perfume, though the bulk of production is done by hand rolling at home. There are about 5,000 incense companies in India that take raw unperfumed sticks hand-rolled by approximately 200,000 women working part-time at home, and then apply their own brand of perfume, and package the sticks for sale. An experienced home-worker can produce 4,000 raw sticks a day. There are about 50 large companies that together account for up to 30% of the market, and around 500 of the companies, including a significant number of the main ones, including Moksh Agarbatti and Cycle Pure, are based in Mysore.
JEWISH TEMPLE IN JERUSALEM:
KETORET:
Ketoret was the incense offered in the Temple in Jerusalem and is stated in the Book of Exodus to be a mixture of stacte, onycha, galbanum and frankincense.
TIBETAN:
Tibetan incense refers to a common style of incense found in Tibet, Nepal, and Bhutan. These incenses have a characteristic "earthy" scent to them. Ingredients vary from cinnamon, clove, and juniper, to kusum flower, ashvagandha, and sahi jeera.
Many Tibetan incenses are thought to have medicinal properties. Their recipes come from ancient Vedic texts that are based on even older Ayurvedic medical texts. The recipes have remained unchanged for centuries.
JAPANESE:
In Japan incense appreciation folklore includes art, culture, history, and ceremony. It can be compared to and has some of the same qualities as music, art, or literature. Incense burning may occasionally take place within the tea ceremony, just like calligraphy, ikebana, and scroll arrangement. The art of incense appreciation, or koh-do, is generally practiced as a separate art form from the tea ceremony, and usually within a tea room of traditional Zen design.
Agarwood (沈香 Jinkō) and sandalwood (白檀 byakudan) are the two most important ingredients in Japanese incense. Agarwood is known as "jinkō" in Japan, which translates as "incense that sinks in water", due to the weight of the resin in the wood. Sandalwood is one of the most calming incense ingredients and lends itself well to meditation. It is also used in the Japanese tea ceremony. The most valued Sandalwood comes from Mysore in the state of Karnataka in India.
Another important ingredient in Japanese incense is kyara (伽羅). Kyara is one kind of agarwood (Japanese incense companies divide agarwood into 6 categories depending on the region obtained and properties of the agarwood). Kyara is currently worth more than its weight in gold.
Some terms used in Japanese incense culture include:
Incense arts: [香道, kodo]
Agarwood: [ 沈香 ] – from heartwood from Aquilaria trees, unique, the incense wood most used in incense ceremony, other names are: lignum aloes or aloeswood, gaharu, jinko, or oud.
Censer/Incense burner: [香爐] – usually small and used for heating incense not burning, or larger and used for burning
Charcoal: [木炭] – only the odorless kind is used.
Incense woods: [ 香木 ] – a naturally fragrant resinous wood.
USAGE:
PRACTICAL:
Incense fragrances can be of such great strength that they obscure other less desirable odours. This utility led to the use of incense in funerary ceremonies because the incense could smother the scent of decay. An example, as well as of religious use, is the giant Botafumeiro thurible that swings from the ceiling of the Cathedral of Santiago de Compostela. It is used in part to mask the scent of the many tired, unwashed pilgrims huddled together in the Cathedral of Santiago de Compostela.
A similar utilitarian use of incense can be found in the post-Reformation Church of England. Although the ceremonial use of incense was abandoned until the Oxford Movement, it was common to have incense (typically frankincense) burned before grand occasions, when the church would be crowded. The frankincense was carried about by a member of the vestry before the service in a vessel called a 'perfuming pan'. In iconography of the day, this vessel is shown to be elongated and flat, with a single long handle on one side. The perfuming pan was used instead of the thurible, as the latter would have likely offended the Protestant sensibilities of the 17th and 18th centuries.
The regular burning of direct-burning incense has been used for chronological measurement in incense clocks. These devices can range from a simple trail of incense material calibrated to burn in a specific time period, to elaborate and ornate instruments with bells or gongs, designed to involve multiple senses.
Incense made from materials such as citronella can repel mosquitoes and other irritating, distracting, or pestilential insects. This use has been deployed in concert with religious uses by Zen Buddhists who claim that the incense that is part of their meditative practice is designed to keep bothersome insects from distracting the practitioner. Currently, more effective pyrethroid-based mosquito repellent incense is widely available in Asia.
Papier d'Arménie was originally sold as a disinfectant as well as for the fragrance.
Incense is also used often by people who smoke indoors and do not want the smell to linger.
AESTHETIC:
Many people burn incense to appreciate its smell, without assigning any other specific significance to it, in the same way that the foregoing items can be produced or consumed solely for the contemplation or enjoyment of the aroma. An example is the kōdō (香道), where (frequently costly) raw incense materials such as agarwood are appreciated in a formal setting.
RELIGIOUS:
Religious use of incense is prevalent in many cultures and may have roots in the practical and aesthetic uses, considering that many of these religions have little else in common. One common motif is incense as a form of sacrificial offering to a deity. Such use was common in Judaic worship and remains in use for example in the Catholic, Orthodox, and Anglican churches, Taoist and Buddhist Chinese jingxiang (敬香 "offer incense), etc.
Aphrodisiac Incense has been used as an aphrodisiac in some cultures. Both ancient Greek and ancient Egyptian mythology suggest the usage of incense by goddesses and nymphs. Incense is thought to heighten sexual desires and sexual attraction.
Time-keeper Incense clocks are used to time social, medical and religious practices in parts of eastern Asia. They are primarily used in Buddhism as a timer of mediation and prayer. Different types of incense burn at different rates; therefore, different incense are used for different practices. The duration of burning ranges from minutes to months.
Healing stone cleanser Incense is claimed to cleanse and restore energy in healing stones. The technique used is called “smudging” and is done by holding a healing stone over the smoke of burning incense for 20 to 30 seconds. Some people believe that this process not only restores energy but eliminates negative energy.
HEALTH RISK FROM INCENSE SMOKE:
Incense smoke contains various contaminants including gaseous pollutants, such as carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), and adsorbed toxic pollutants (polycyclic aromatic hydrocarbons and toxic metals). The solid particles range between ~10 and 500 nm. In a comparison, Indian sandalwood was found to have the highest emission rate, followed by Japanese aloeswood, then Taiwanese aloeswood, while Chinese smokeless sandalwood had the least.
Research carried out in Taiwan in 2001 linked the burning of incense sticks to the slow accumulation of potential carcinogens in a poorly ventilated environment by measuring the levels of polycyclic aromatic hydrocarbons (including benzopyrene) within Buddhist temples. The study found gaseous aliphatic aldehydes, which are carcinogenic and mutagenic, in incense smoke.
A survey of risk factors for lung cancer, also conducted in Taiwan, noted an inverse association between incense burning and adenocarcinoma of the lung, though the finding was not deemed significant.
In contrast, epidemiologists at the Hong Kong Anti-Cancer Society, Aichi Cancer Center in Nagoya, and several other centers found: "No association was found between exposure to incense burning and respiratory symptoms like chronic cough, chronic sputum, chronic bronchitis, runny nose, wheezing, asthma, allergic rhinitis, or pneumonia among the three populations studied: i.e. primary school children, their non-smoking mothers, or a group of older non-smoking female controls. Incense burning did not affect lung cancer risk among non-smokers, but it significantly reduced risk among smokers, even after adjusting for lifetime smoking amount." However, the researchers qualified their findings by noting that incense burning in the studied population was associated with certain low-cancer-risk dietary habits, and concluded that "diet can be a significant confounder of epidemiological studies on air pollution and respiratory health."
Although several studies have not shown a link between incense and lung cancer, many other types of cancer have been directly linked to burning incense. A study published in 2008 in the medical journal Cancer found that incense use is associated with a statistically significant higher risk of cancers of the upper respiratory tract, with the exception of nasopharyngeal cancer. Those who used incense heavily also were 80% more likely to develop squamous-cell carcinomas. The link between incense use and increased cancer risk held when the researchers weighed other factors, including cigarette smoking, diet and drinking habits. The research team noted that "This association is consistent with a large number of studies identifying carcinogens in incense smoke, and given the widespread and sometimes involuntary exposure to smoke from burning incense, these findings carry significant public health implications."
In 2015, the South China University of Technology found toxicity of incense to Chinese hamsters' ovarian cells to be even higher than cigarettes.
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.
