In every climate zone, humans have discovered plants that can be used as incenses for ritual, medicinal, and psychoactive purposes. The inhabitants of the oases in the extremely arid Atacama Desert (northern Chile) use the aromatic, resinous herbage of Fabiana bryoides as a shamanic incense. (Watercolor: Donna Torres)

The use of incenses for ritual, religious, magical, medicinal, hygienic, and other purposes is found throughout the world. Incense is a transcultural phenomenon. In most cultures, incense is regarded as a “food of the gods.” Some incenses are used for their unusually pleasant scents. Others are burned for their pharmacological effects. The latter typically have an unpleasant smell but induce psychoactive effects. Many parts of plants (such as laurel leaves; cf. Laurus nobilis) are used as incense during esoteric rituals for their allegedly magical effects. From the form that the smoke takes on as it rises, the will of the gods or the malicious intent of demons can be read. Some incenses stimulate erotic feelings, while others are said to protect house and farm from diseases, spirits, and thieves. The use of incense gave rise to the practice of smoking (cf. smoking blends).

There are three main cultural centers for the use of incense: the ancient world (including the ancient Orient), the Indian subcontinent (including the Himalayan region), and Mesoamerica. The Native American incense culture developed separately and independently, while strong reciprocal influences existed between the ancient world, the Orient, and India. Extensive trade relationships between India and Egypt, resulting in the exchange of spices, medicinal plants, inebriants, and incenses, existed in ancient times. Egyptian graves dating to late antiquity have yielded containers filled with aromatic substances and inscribed with Indian and Chinese writing (Wollner 1995, 19).

The use of incense was very widespread during antiquity. Greek, Egyptian, and Roman gods all had their respective incenses (cf. Rätsch 1995a, 312 ff.*). In the ancient literature, e.g., the writings of Dioscorides and Pliny, the laurel (Laurus nobilis) was known as daphne and was attributed with powerful mind-altering properties. So far, however, all attempts to use laurel for psychoactive purposes have failed (see Rätsch 1996b), and no psychoactive constituents have been found to date (Hogg et al. 1974). This suggests that daphne was likely a name given to at least one or more other plants in antiquity. Perhaps one of these daphne, whose botanical identity is now unknown, was psychoactive.

“In Mexico, they know of a very unusual juniper bush, Juniperus thurifera (L.), and in Tibet we even find a species of juniper that grows at an altitude of 4,000 meters [and] that the Chinese call ‘hyiang ching’ (scented green). Juniperus scopulorum (Sarg.) and Cupressus benthamii(Endl.) are found in Mexico, while one encounters Juniperus squamata (Lamb.) and recurva in Nepal and Kashmir and Juniperus sabina (L.; sade tree) in Siberia. All of these juniper plants are different from one another and are also used by the indigenous medicine men for the most varied of treatments for diseases.”

 

ARNOLD KRUMM-HELLER OSMOLOGISCHE HEILKUNDE [THE OSMOLOGICAL ART OF HEALING] (1955, 28)

 

It is very likely that white henbane (Hyoscyamus albus), known as apollinaris, or the plant of Apollo, was the inebriant that the Pythia of Delphi, the famous oracular priestess of antiquity, used to enter a state of ecstasy (cf. also Catha edulis). The mysterious smoke of Delphi that the Pythia inhaled before sitting on the tripod and uttering her prophecies was most probably produced by burning henbane seeds.

During the Middle Ages, “sleep-bringing” incenses were used in medicine. These almost certainly had powerful psychoactive effects. A fourteenth-century Roman codex contains a recipe for such an incense; it consisted of equal parts of arsenic,427 mandrake root (Mandragora officinarum), and opium (see Papaver somniferum). Storax (the gum resin of Liquidambar officinalis) and olibanum (= frankincense; the resin from Boswellia sacra) were also added to this already potent blend, which was then strewn over glowing coals. This recipe was used as an alternative to soporific sponges and is also somewhat reminiscent of witches’ ointments.

During the Renaissance, the burning of incense was construed as an alchemical process (Krumm-Heller 1934, 1955). Matter is transformed through fire and then affects the mind, whether pharmacologically or psychologically. The element of fire creates smoke out of the element of earth, and the smoke joins with the element of air to “transform the mind.” That Agrippa’s recipe for incense (see below) has the ability to transform the mind is clear: he names many psychoactive plants (man-drake, henbane, hemp, poppy) whose smoke one should inhale. It was said that one could also conjure demons—in the ancient sense of the word—with incense:

 

For the purpose of prophecy, incenses for stimulating the imagination shall be preferred. These, in correspondence with certain higher spirits, make us skilled to receive the divine inspiration. . . . Thus, when a smoke is made from coriander and celery, or henbane along with hemlock, the demons should gather momentarily, and this is why these plants are called spirit herbs. (1.43) [1387]

 

In Asia and Arabia, the most valuable incense was considered to be the dark brown, resinous lignum aloe (Aquilaria agallocha), also known as aloe wood, agar wood, agar-agar, garugaru, and lignum aspalathi. It was used primarily for ritual purposes. There have been repeated reports of psychoactive effects resulting from burning lignum aloe or inhaling the very expensive essential oil extracted from it. Lignum aloe contains sesquiterpenes, chromone derivatives, a coumarin lignan derivative, and an alkaloid (Kletter 1992, 308).

Today, incenses continue to play a significant ceremonial and symbolic role during the commencement of entheogenic rituals around the world. Breuzinho (from Protium heptaphyllum and Protium spp.) is the main incense used by the Santo Daime cult (cf. ayahuasca). In Afro-American possession cults, various aromatic herbs and mints are burned (cf. madzoka medicine) to greet and attract the orishas (the Yoruba deities) (Voeks 1989, 123*). The wood of Juniperus species, known as cedar, is used as a fumigant in the North American peyote cult (the Native American Church; cf. Lophophora williamsii). Copal (from Protium copalBursera spp.) or pine resin (Pinus spp.) is burned during the Mesoamerican balche’ ritual (cf. balche’). During the Japanese tea ceremony, incense sticks made of lignum aloe or special tea ceremony blends made of several ingredients are burned (cf. Camellia sinensis).

The burning of certain plants during healing ceremonies is a widespread phenomenon. In the Vaupés region of Colombia, the leaves of a Rubiaceae (Retiniphyllum concolor [Spruce ex Benth.] Muell. Arg.) are used for this purpose (Schultes 1978a, 196*). In Switzerland, juniper branches (Juniperus communis L.) are used.

Since ancient times, incenses have played a central role in shamanism. There is hardly any shamanic activity that does not incorporate the burning or fumigation of precisely defined plants or substances. Various species of juniper (cf. Juniperus recurva) grow throughout the world, particularly in Europe, Asia (the Himalayan regions and Mongolia), and North America. They are used for ritual, magical, and medicinal purposes almost wherever they grow. In most cultures familiar with shamanism, juniper has a reputation for being a shamanic incense. Juniper is probably one of the oldest—it may even be the oldest—incense used by humans. This is certainly due to the fact that its leaves exude an exquisite and spicy aroma, even when burned fresh (Rätsch 1996a, 1996b).

Shamans in the Colombian Vaupés region inhale the aromatic balsam of Styrax tessmannii Perk., which is purported to be psychoactive (Schultes and Raffauf 1986, 277*).

In Peru and northern Chile (Atacama region), a number of incenses (from Fabiana spp., Mentha spp., Senecio spp.) are referred to by the names koak’oakhoa, et cetera. They are used primarily during the ceremonies known as señaladas, when they are burned as an offering to the mother-goddess Pachamama (cf. Erythoxylum coca).

During shamanic healings and rituals, the modern Nahuat (Mexico) burn a blend of tobacco leaves (Nicotiana tabacum) and pine resin (from a Pinus species). Such an incense is said to keep away the malicious soul-eaters that live in Talocan (“the great flower of darkness”), the realm of dreams (Knab 1995, 29*). Mazatec shamans inhale large amounts of a blend of copal (resin from a Pinus species) and chili pods (Capsicum spp.) before they begin their divinations. This incense blend is said to have psychoactive effects (Jonathan Ott, pers. comm.). The Cuna of the San Blas Islands (Panama) burn generous amounts of chili pods, often mixed with cocoa beans (Theobroma cacao), in order to dispel malicious spirits (Duke 1975, 286*).

Among the North American Plains Indians, the most important ritual and shamanic incense is sage (Artemisia spp.). The Flathead use an incense of qepqepte (Artemisia ludoviciana Nutt.) and cqelshp(Pseudotsuga menziesii[Mirbel.] Franco) in their sweat lodge ceremonies (Hart 1979, 278*).

The Indians of the Southwest prefer the piñon pine (Pinus edulis), which has played an important role in native culture as a food, medicine, and incense for at least six thousand years. The seeds are edible and high in nutritional value. The needles and resin are a component of many medicines. The Navajo believe that a squirrel planted the piñon pine (cá’ol) at the beginning of creation and that the first humans nourished themselves exclusively on pine nuts (nictc’íi pináa’). They use the resin as an incense in the night chant, their most important religious healing ceremony. The Tewa and Santa Clara Pueblo regard the pine as the first of all trees and its seeds as the first food (). The pine is the most important incense of the Pueblo Indians. The Zuni call the tree he’sho tsi’tonne, “gum branch.” The Hopi use primarily the needles of the pine as incense. Occasionally they also crumble the needles, mix them with wild tobacco (Nicotiana sp.), and use the product as an incense powder. After a burial ceremony, pine resin is tossed into the fire at the house of the surviving relatives so that they can “smudge” and purify themselves. The resin is also used to protect against magic. For this purpose, the Hopi rub a drop of the resin onto their foreheads (Lanner 1981).

Psychoactive Incenses

 

The psychoactivity of some of the incenses listed here is doubtful.

(from Fischer 1971; Krumm-Heller 1934; Krumm-Heller 1955; Ludwig 1982, 134 f.*; Rätsch 1995; Rätsch 1996a; Rätsch 1996b; Vinci 1980; supplemented)

 

 

 

 

 

Many manufacturers of incense sticks offer varieties that hint at psychoactive effects. However, these products do not contain any true psychoactive substances. (Incense stick packaging)

Shamans often use the leaves, branches, or bark of sacred trees as ritual and even psychoactive incenses. In the Himalayan region, shamans inhale copious amounts of juniper smoke (see Juniperus recurva). The Chilean Mapuche shamans (machi), most of whom are female, use the cinnamon-scented bark of the sacred canelo tree (Drimys winteri Forst.434; Magnoliaceae), known locally as voiquefoique, or foye, as an incense at all of their tribal and healing ceremonies (Mösbach 1992, 79*). Whether the incense actually does have psychoactive effects remains an open question; in any case, the Mapuche use an infusion of the leaves as an inebriating narcotic (Houghton and Manby 1985, 93*). The machi regard the tree as a panacea and use the bark as a tonic and stimulant (Mösbach 1992, 79*). The bark contains an essential oil, a pungent resin, and tannin. The leaves contain sesquiterpenes, such as drimendiol (Brown 1994; Wren 1988, 284*). Canelo is often combined with Latua pubifloraFabiana imbricata, and Cestrum parqui and burned as a psychedelic incense.

 

The Mapuche shamans of southern Chile use the sacred canelo tree (Drimys winteri) as a ritual incense. (Photographed in Valdivia, southern Chile)

 

 

The aromatic leaves of the Chilean boldo tree (Peumus boldus) are used as a ritual incense and also are purported to have psychoactive effects.

 

 

Poison ivy (Toxicodendron radicans [syn. Rhus radicans]) may have been used as a psychoactive incense in certain “witches’ cults.”

 

 

Malai sorcerers inhale the sweetish smoke of benzoin to help them change their shape. The essential oil distilled from benzoin has been reported to have inebriating or mood-enhancing effects.

 

 

Lignum aloe (Aquilaria agallocha), which becomes enriched with an aromatic resin as a result of fungal contamination, is a valuable incense. Arabian sheiks esteem the essential oil of lignum aloe, known as ud, as a highly effective aphrodisiac. In aromatherapy, the plant is considered to have potent effects upon the mind.

 

Another ritual incense attributed with psychoactive effects is composed of the leaves of the Chilean boldo tree (Peumus boldus), which contain alkaloids (1% boldine in the leaves; also norboldine) that have stimulating and possibly psychoactive effects (Mösbach 1992, 80*). Boldine is an aporphine alkaloid (cf. Nymphaea ampla) that increases the secretion of gastric juices and thus aids in digestion; it also promotes bile production and is antispasmodic. Overdoses and chronic use are said to have toxic effects. Psychotropic effects and even hallucinations have been mentioned (Pahlow 1993, 365*). The flowery-fruity-scented essential oil contains ascaridol, cineol, eucalyptol, and p-cymol and has anthelmintic effects.

There are a number of other, similar preparations, all of which are no longer available. Many contemporary purveyors of incenses offer blends with psychoactive effects (based on their own self-experimentation). Pharmacognostic research has demonstrated that these often contain the branch tips of Fabiana imbricata and various resins (olibanum and others).

Some incenses are used to aromatize other psychoactive substances, such as betel nut (Areca catechu), ipadú (Erythroxylum coca), opium (Papaver somniferum), and tobacco (Nicotiana tabacum).

Activity and Pharmacology of Incenses

 

Today, there are a variety of scientific models for explaining the psychoactive effects of smoke and scent on human consciousness (cf. Laatsch 1991). There are essentially three mechanisms of action that can play a role, both alone and in combination with one another (from Rätsch 1996b):

“I was told that in earlier times the witches knew an herb called kat.[436] Used with incense, it opened the inner eye, the unconscious. In combination with another herb, sumac,[ 437] it produced hallucinations and was therefore not to be taken too frequently. When both herbs were used in the proper way, one could acquire the ability to leave one’s body. Unfortunately, the witches of today no longer know which herbs they were, although both are said to grow in England. It is also said that a woman will appear more beautiful if a man inhales incense mixed with kat. Magicians use something similar for the same purpose. Their mixture contains hemp [Cannabis sativa] and many other ingredients with tonic effects.”

(1965, 109)

 

1. The smoke may contain pharmacologically active substances that, at appropriate dosages, can act like neurotransmitters or their antagonists in the nervous system.

2. The smoke may give off a characteristic scent with a demonstrably strong psychological activity.

 

Nearly all of the plants or raw extracts used as incenses contain essential oils, which are responsible for their scent. Experiments have demonstrated that certain odors induce powerful changes in the brain’s activity and thus unequivocal alterations in consciousness (Steele 1991*, 1992*, 1993*). It is assumed that these aromatic substances elicit primarily psychotogenic effects, i.e., although the substance does not act pharmacologically, the experience of the scent can alter a person’s state of consciousness (scent as a catalyst for memory!). Some essential oils have been observed to have both pharmacological and psychological effects. When inhaled or taken internally, higher dosages of certain essential oils can result in powerful states of inebriation that from a neurophysiological perspective cannot yet be fully explained. The following incenses have been observed to produce the strongest psychoactive effects as a result of their essential oils: camphor, cedar (Cedrus spp.), cinnamon (Cinnamomum verum), cloves (Syzygium aromaticum (L.) Merr. et Perry [syn. Eugenia caryophyllata Thunberg]), copal, coriander, damiana, juniper (Juniperusspp.), laurel, lignum aloe, mugwort (Artemisia spp.), rosemary (Rosmarinus officinalis L.), sade tree (Juniperus sabina), various sages (Artemisia spp.Salvia spp.), and wild rosemary (Ledum palustre). In addition, some of the constituents in essential oils, including thujone, eugenol, myristicin, safrole, and ledol, also have powerful psychoactive effects.

 

3. The smoke contains pheromones, which carry messages to the brain via the sensory organs.

 

Pheromones are rather simple chemical compounds that are related to hormones and function as sexual attractors in the plant and animal kingdoms (Jaenicke 1972). Although often odorless, they are as a result that much more effective. Animals and humans exude pheromones when it is time to mate. When a potential partner breathes in these molecules, they induce in him or her an irresistible urge to copulate. Male and female pheromones often differ in their chemical makeup. Certain aromatic substances that are produced in the fungal, plant, and animal kingdoms (e.g., the scent of the truffle, Tuber spp.) are chemically or structurally analogous or even identical to human pheromones. When these substances are inhaled in an incense, they can inflame a person’s amorous desires. Vanillin, the main aromatic substance in vanilla (Vanilla planiflora; cf. balche’), which is also found in many balsams and resins, is very closely related to human pheromones and appears to exert a corresponding effect upon the nervous system. Almost all of the plants that contain vanillin are traditionally regarded as aphrodisiacs. The following incenses contain or create substances that are pheromone analogs: ambergris, benzoin, cloves, copal, ladanum (the exudate of Cistus ladaniferus L. [syn. Cistus ladanifer L.]), Peruvian balsam (Myroxylon balsamum [L.] Harms var. pereirae[Royle] Harms [syn. Myroxylon pereira (Royle) Baill.]), rockrose and gray-haired rockrose (Cistus creticus L. [syn. Cistus incanus L. ssp. creticus] = Cretian rockrose), storax (Liquidambar spp.), tolu balsam (Myroxylon balsamum[L.] Harms var. balsamum), and white sandalwood.

The effects of incenses on humans result from a complex series of psychological, pharmacological, and hormonal events. Unfortunately, there has been almost no research in this area. In addition, other factors that can play a role include hyperventilation, the “choking fits” that may occur as a result of deep inhalation, oxygen deprivation (which can also lead to hyperventilation), combination with other activities (such as drumming, rattling, body postures, songs), and cognitive structures. For example, some shamans inhale incense to the beat of a drum. In this manner, they are able to precisely control the rate at which they hyperventilate and the depth to which they inhale the incense. This enables them to purposefully induce and control different altered states of consciousness.
