Tabernanthe iboga (iboga) is a perennial rainforest shrub native to West Africa. An evergreen bush indigenous to Gabon, the Democratic Republic of Congo, and the Republic of Congo, it is cultivated across West Africa.
In African traditional medicine and rituals, chewing the yellow-colored root or bark is used to produce hallucinations and near-death outcomes, with some fatalities occurring. Preliminary research indicates that ibogaine, an alkaloid constituent of iboga roots and bark, has potential for treating addiction to opioids and other substances of abuse. In high doses, ibogaine is considered to be toxic, and has caused serious comorbidities when used with opioids or prescription drugs. The United States Drug Enforcement Agency (DEA) lists ibogaine as a controlled substance of the Controlled Substances Act.

Iboga is native to tropical forests, preferring moist soil in partial shade. It bears dark green, narrow leaves and clusters of white tubular flowers on an erect and branching stem, with yellow-orange fruits resembling an olive.
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. Its flowers are white and pink, while the fruit can be either an elongated oval shape, or a round spherical shape, both having an orange color. Its yellow-colored roots contain a number of indole alkaloids, most notably ibogaine, which is found in the highest concentration in the root-bark. The root material, bitter in taste, causes anesthetic sensation in the mouth as well as systemic numbness to the skin.
Indole alkaloids, which make up about 6% of the root chemical composition of iboga, include:
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. 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. Bwitists have been subject to persecution by Catholic missionaries. Léon M'ba, before becoming the first President of Gabon in 1960, defended the Bwiti religion and the use of iboga in French colonial courts. On June 6, 2000, the Council of Ministers of the Republic of Gabon declared Tabernanthe iboga to be a national treasure.
Addiction treatment claims
Anecdotal reports of self-treated opioid addicts indicated a reduced desire to sustain opiate abuse following iboga ingestion. Since 1970, iboga has been legally prohibited in the United States following several fatalities. Preliminary research for the potential use of ibogaine in the treatment of opioid dependence is ongoing in the 21st century, with several clinics using ibogaine in Western countries, Panama, and Caribbean islands. 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. Ibogaine is a k-opioid agonist which may be the mechanism for how it affects opiate withdrawal symptoms.
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. In most other countries, it remains unregulated and unlicensed.
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". Covert, illegal neighborhood clinics are also known to exist in the United States, despite active DEA surveillance. 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.
Iboga is outlawed or restricted in Belgium, Poland, Denmark, Croatia, France, Sweden, and Switzerland. In the United States, iboga is classified by the Controlled Substances Act on the list of schedule I drugs.
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.
Exportation of iboga from Gabon is illegal since the passage of a 1994 cultural protection law.
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.
Documentary films about iboga
- Iboga, les hommes du bois sacré (2002)
- In this French-language film, Gilbert Kelner documents modern Bwiti practices and Babongo perspectives on iboga. Odisea broadcast a Spanish-dubbed version titled Los hombres de la madera ("The Men of the Wood").
- Ibogaine: Rite of Passage (2004)
- Directed by Ben Deloenen. A 34-year-old heroin addict undergoes ibogaine treatment with Dr Martin Polanco at the Ibogaine Association, a clinic in Rosarito Mexico. Deloenen interviews people formerly addicted to heroin, cocaine, and methamphetamine, who share their perspectives about ibogaine treatment. In Gabon, a Babongo woman receives iboga root for her depressive malaise. Deloenen visually contrasts this Western, clinical use of ibogaine with the Bwiti use of iboga root bark, but emphasizes the Western context.
