Additional Information: From Wiki: "Native to western Central Africa. Iboga stimulates the central nervous system when taken in small doses and induces visions in larger doses. In parts of Africa where the plant grows the bark of the root is chewed for various pharmacological or ritualistic purposes. Ibogaine, the active alkaloid, is also used to treat substance abuse disorders and depression. The Iboga tree is the central pillar of the Bwiti spiritual practice in West-Central Africa, mainly Gabon, Cameroon and the Republic of the Congo, which uses the alkaloid-containing roots of the plant in a number of ceremonies. 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, which are usually performed at night. Bwitists have been subject to persecution by Catholic missionaries, who to this day are thoroughly opposed to the growing spiritual practice 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."
