Tabernanthe iboga

Iboga (Tabernanthe iboga), also known as Black bugbane, is a perennial rainforest shrub and hallucinogen, native to western Africa. Iboga stimulates the central nervous system when taken in small doses and induces visions in larger doses.

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. It has small green leaves. Its flowers are white and pink, while the elongated, oval-shaped fruit are orange. Its yellow-coloured roots contains 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 an anaesthetic sensation in the mouth as well as systemic numbness to the skin.


Traditional use

The Iboga tree is the central pillar of the Bwiti religion practiced in West-Central Africa, mainly Gabon, Cameroon and the Republic of the Congo, which utilises the alkaloid-containing roots of the plant in a number of ceremonies. Iboga is taken in massive doses by initiates when entering the religion, and on a more regular basis is eaten in smaller doses in connection with rituals and tribal dances, which is usually performed at night time. Bwitists have been subject to persecution by Catholic missionaries, who to this day are thoroughly opposed to the growing religious movement of Bwiti. 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

Outside Africa, iboga extracts as well as the purified alkaloid ibogaine are used in treating opiate addiction. The therapy may last several days and upon completion the subject is generally no longer physically dependent. One methadone patient said in the Dutch behind-the-news show 2 vandaag that in just four days he reached a state that normally would have taken him three months, but without the agony. Evidence suggests that ibogaine may also help to interrupt addiction to alcohol and nicotine. The pharmacological effects are rather undisputed with hundreds of peer reviewed papers in support but formal clinical studies have not been completed.

Legal status

Iboga is outlawed or restricted in the U.S., Belgium, Sweden, Switzerland and Denmark. Root material and extracts thereof is obtainable through various European smart shops.
