About
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 use in traditional medicine and rituals.
T. iboga can grow up to 10 meters tall and contains psychoactive indole alkaloids, especially ibogaine, concentrated in its root bark, which produces strong neurological effects. It is used in both low doses as a stimulant and in high doses to induce intense dreamlike and hallucinatory states during rituals.
Safety
Indole alkaloids make up about 6% of the root chemical composition of iboga. Alkaloids that are present in more than 1% in root bark are: (in descending order)
