Tabernanthe iboga | |
Tabernanthe iboga (iboga) is an evergreen rainforest shrub native to Central Africa. A member of the Apocynaceae family indigenous to Gabon, the Democratic Republic of Congo, and the Republic of Congo, it is cultivated across Central Africa for its medicinal and other effects.
In African traditional medicine and rituals, the yellowish root or bark is used to produce hallucinations and near-death outcomes, with some fatalities occurring. [3] [4] In high doses, ibogaine is considered to be toxic, and has caused serious comorbidities when used with opioids or prescription drugs. [3] [5] The United States Drug Enforcement Administration (DEA) lists ibogaine as a controlled substance of the Controlled Substances Act. [3]

T. iboga is native to tropical forests, preferring moist soil in partial shade. [3] It bears dark green, narrow leaves and clusters of tubular flowers on an erect and branching stem, with yellow-orange fruits resembling chili pepper. [3]
Normally growing to a height of 2 m, T. iboga may eventually grow into a small tree up to 10 m tall, given the right conditions. The flowers are yellowish-white or pink and followed by a fruit, orange at maturity, that may be either globose or fusiform. Its yellow-fleshed roots contain a number of indole alkaloids, most notably ibogaine, which is found in the highest concentration in the bark of the roots. The root material, bitter in taste, causes a degree of anaesthesia in the mouth as well as systemic numbness of the skin. [6]
Tabernanthe iboga was described by Henri Ernest Baillon and published in Bulletin Mensuel de la Société Linnéenne de Paris 1: 783 in the year 1889.
The genus name Tabernanthe is a compound of the Latin taberna, "tavern"/"hut"/"(market) stall" and Greek: ἄνθος (anthos) "flower" – giving a literal meaning of "tavern flower". On the other hand, it may equally well have been intended (by way of a type of botanical shorthand) to mean "having a flower resembling that of plants belonging to the genus Tabernaemontana " (q.v.). If the first conjecture is the correct one, the name could also have been intended to suggest that the plant is cultivated near huts, sold at market stalls or even that – like the beverages sold at a tavern – the plant is intoxicating, all of which alternatives would constitute apt descriptions of an oft-cultivated and popular psychoactive plant. The specific name iboga comes from the Myene name for the plant, [7] which was also borrowed into a number of other regional languages with mild variation. [8]
The first (probable...and confused) reference to Iboga is that of Bowdich in chapter 13 of his "Mission from Cape Coast Castle to Ashantee..." of 1819
The Eroga, a favourite but violent medicine, is no doubt a fungus, for they describe it as growing on a tree called the Ocamboo, when decaying; they burn it first, and take as much as would lay on a shilling.
If this is indeed a reference to the drug derived from Tabernanthe iboga (Eroga appears to be a variant form of the names iboga and eboka) it is, of course, grossly in error in its assumption that iboga is not a plant but a fungus. Notable however is the observation of the potency of the drug – effective in small quantities. The description of the plant as growing on a tree is puzzling: Tabernanthe iboga does not usually grow as an epiphyte – if at all. [9] [10]
The ritual use of iboga in Africa was first reported by French and Belgian explorers in the 19th century, beginning with the work of French naval surgeon and explorer of Gabon Griffon du Bellay, [11] who identified it correctly as a shrub belonging to the Apocynaceae – as recorded in a short essay by Charles Eugène Aubry-Lecomte on the plant poisons of West Africa, published in the year 1864.
Parmi les plantes rares ou nouvelles rapportées par le docteur Griffon du Bellay, la famille des apocynées contient encore deux poisons; l'un, nommé iboga, n'est toxique qu'à hautes doses et a l'état frais. Pris en petit quantité, il est aphrodisiaque et stimulante du systeme nerveux; les guerriers et chasseurs en font grand usage pour se tenir éveillés dans les affûts de nuit; de même que pour le M'boundou, le principe actif réside dans la racine qu'on mâche comme la coca.
[ Translation: Among the rare or new plants brought back by Dr. Griffon du Bellay, the plant family Apocynaceae contains two further poisons; the first of these, called Iboga, is only toxic in high doses and in the fresh state. Taken in small quantities, it is an aphrodisiac and stimulant of the (central) nervous system; warriors and hunters make considerable use of it in order to stay awake during their night vigils; as with the (plant) M'boundou, the active principle (of Iboga) resides in the root which is chewed like coca (leaf) ]. [12]
Indole alkaloids make up about 6% of the root chemical composition of iboga. [3] Alkaloids that are present in more than 1% in root bark are: [13] (in descending order)
18-Methoxycoronaridine, a synthetic derivative of ibogaine, also occurs naturally in this plant. [3] [4]
The Iboga tree is central to the Bwiti spiritual practices in West-Central Africa, mainly Gabon, Cameroon, and the Republic of the Congo, where the alkaloid-containing roots or bark are used in various ceremonies to create a near-death experience. [3] Iboga is taken in massive doses by initiates of this spiritual practice, and on a more regular basis is eaten in smaller doses in connection with rituals and tribal dances performed at night.
While in lower doses iboga has a stimulant effect and is used to maintain alertness while hunting, [14] [15] in moderate or high doses, iboga induces dream-like states with vivid visions and hallucinations. [3]
Anecdotal reports of self-treated opioid addicts indicated a reduced desire to sustain opiate abuse following iboga ingestion. [3] Since 1970, iboga has been legally prohibited in the United States following several fatalities. [3] [4] Iboga extracts, as well as the purified alkaloid ibogaine, have attracted attention because of their purported ability to reverse addiction to drugs such as alcohol and opiates. [3]
Ibogaine is classified as a schedule 1 controlled substance in the United States, and is not approved there for addiction treatment (or any other therapeutic use) because of its hallucinogenic and cardiovascular side effects, as well as the absence of safety and efficacy data in human subjects. [3] [5] In most other countries, it remains unregulated and unlicensed. [16]
Independent ibogaine treatment clinics have emerged in Mexico, Canada, the Netherlands, South Africa, and New Zealand, all operating in what has been described as a "legal gray area". [16] [17] Covert, illegal neighborhood clinics are also known to exist in the United States, despite active DEA surveillance. [15] Addiction specialists warn that the treatment of drug dependence with ibogaine in non-medical settings, without expert supervision and unaccompanied by appropriate psychosocial care, can be dangerous – and, in approximately one case in 300, potentially fatal. [3] [17]
Ibogaine may induce nausea, vomiting, tremors, and headaches. [3] When ibogaine is used chronically, manic episodes lasting for several days may occur, accompanied by insomnia, irritability, delusions, aggressive behavior, and thoughts of suicide, among other effects. [3] [18]
Iboga is outlawed or restricted in Belgium, Poland, Denmark, Croatia, France, [19] Sweden, and Switzerland. In the United States, ibogaine is classified by the Controlled Substances Act on the list of schedule I drugs, [3] although the plant itself remains unscheduled.
Non-profit organization Föreningen för hollistisk missbruksvård is trying to convince the Swedish government to start up clinical investigations of its anti-addictive properties, loosen up the prohibition law against ibogaine, and allow the creation of treatment facilities in Sweden. [20]
Exportation of iboga from Gabon is illegal since the passage of a 1994 cultural protection law. [21]
While little data is available on the exploitation and existing habitat of the iboga plant, the destructive effects of harvesting and slow growth could have already severely damaged the wild iboga population. [22]
Apocynaceae is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here.
Bwiti is a spiritual discipline of the forest-dwelling Punu people and Mitsogo peoples of Gabon and by the Fang people of Gabon. Modern Bwiti incorporates animism, ancestor worship, and in some cases, Christianity, into a syncretistic belief system.
An oneirogen, from the Greek ὄνειρος óneiros meaning "dream" and gen "to create", is a substance or other stimulus which produces or enhances dreamlike states of consciousness. This is characterized by an immersive dream state similar to REM sleep, which can range from realistic to alien or abstract.
Howard Lotsof was an American scientific researcher who discovered and pioneered the use of ibogaine as an approach in Western medicine in the treatment of substance addictions. In 1962, at the age of 19, Lotsof was addicted to heroin and accidentally discovered the anti-addictive effects of ibogaine. He later attended Fairleigh Dickinson University and then New York University, graduating with a degree in film in 1976.
Ibogaine is a psychoactive indole alkaloid obtained either by extraction from plants in the family Apocynaceae such as Tabernanthe iboga, Voacanga africana, and Tabernaemontana undulata or by semi-synthesis from the precursor compound voacangine, another plant alkaloid. The total synthesis of ibogaine was described in 1956. Structural elucidation by X-ray crystallography was completed in 1960.
Griffonia simplicifolia is a woody climbing shrub native to West Africa and Central Africa. It grows to about 3 m, and bears greenish flowers followed by black pods.
Voacangine is an alkaloid found predominantly in the root bark of the Voacanga africana tree, as well as in other plants such as Tabernanthe iboga, Tabernaemontana africana, Trachelospermum jasminoides, Tabernaemontana divaricata and Ervatamia yunnanensis. It is an iboga alkaloid which commonly serves as a precursor for the semi-synthesis of ibogaine. It has been demonstrated in animals to have similar anti-addictive properties to ibogaine itself. It also potentiates the effects of barbiturates. Under UV-A and UV-B light its crystals fluoresce blue-green, and it is soluble in ethanol.
The Exposition Universelle of 1867, better known in English as the 1867 Paris Exposition, was a world's fair held in Paris, France, from 1 April to 3 November 1867. It was the second of ten major expositions held in the city between 1855 and 1937. A number of nations were represented at the fair. Following a decree of Emperor Napoleon III, the exposition was prepared as early as 1864, in the midst of the renovation of Paris, marking the culmination of the Second French Empire. Visitors included Tsar Alexander II of Russia, a brother of the King William and Otto von Bismarck of Prussia, Prince Metternich and Franz Josef of Austria, Ottoman Sultan Abdülaziz, and the Khedive of Egypt Isma'il.
Indole alkaloids are a class of alkaloids containing a structural moiety of indole; many indole alkaloids also include isoprene groups and are thus called terpene indole or secologanin tryptamine alkaloids. Containing more than 4100 known different compounds, it is one of the largest classes of alkaloids. Many of them possess significant physiological activity and some of them are used in medicine. The amino acid tryptophan is the biochemical precursor of indole alkaloids.
Voacanga africana is a small tree native to tropical Africa belonging to the family Apocynaceae that grows to 6 m (20 ft) in height and bears leaves that are up to 30 cm (12 in) in length. The yellow or white flowers are succeeded by paired, follicular, dehiscent fruit with a mottled green exocarp and a pulpy, yellow mesocarp surrounding the seeds. The plant contains alkaloids acting as CNS depressants and hypotensives.
Griffonia is a genus of central African flowering plants in the legume family, Fabaceae. It belongs to the subfamily Cercidoideae. Griffonia is known to have a high concentration of 5-HTP in its seeds.
Noribogaine, or 12-hydroxyibogamine, is the principal psychoactive metabolite of the oneirogen ibogaine. It is thought to be involved in the antiaddictive effects of ibogaine-containing plant extracts, such as Tabernanthe iboga.

Iboga-type alkaloids are a set of monoterpene indole alkaloids comprising naturally occurring compounds found in Tabernanthe and Tabernaemontana, as well as synthetic structural analogs. Naturally occurring iboga-type alkaloids include ibogamine, ibogaine, tabernanthine, and other substituted ibogamines. Many iboga-type alkaloids display biological activities such as cardiac toxicity and psychoactive effects, and some have been studied as potential treatments for drug addiction.
Ibogaline is an alkaloid found in Tabernanthe iboga along with the related chemical compounds ibogaine, ibogamine, and other minor alkaloids. It is a relatively smaller component of Tabernanthe iboga root bark total alkaloids (TA) content. It is also present in Tabernaemontana species such as Tabernaemontana australis which shares similar ibogan-biosynthetic pathways. The percentage of ibogaline in T. iboga root bark is up to 15% TA with ibogaine constituting 80% of the alkaloids and ibogamine up to 5%.
This is an overview of the legality of ibogaine by country. Ibogaine is not included on the UN International Narcotics Control Board's Green List, or List of Psychoactive Substances under International Control. However, since 1989, it has been on the list of doping substances banned by the International Olympic Committee and the International Union of Cyclists because of its stimulant properties.
Mostuea is one of only three genera of flowering plants belonging to the small family Gelsemiaceae. Mostuea and Gelsemium were formerly placed in the family Loganiaceae, while Pteleocarpa was placed variously in the families Icacinaceae, Cardiopteridaceae, Boraginaceae, and others, before the description of the Gelsemiaceae was altered formally to accommodate it in 2014. Mostuea is native to Africa and South America. Anecdotal evidence suggests that the roots of certain Mostuea species are used as ritual aphrodisiacs and entheogens in West Tropical Africa.
