What does the perennial rainforest shrub containing an active alkaloid also found in Voacanga africana and Tabernaemontana undulata induce in large doses?
Tabernanthe iboga Tabernanthe iboga or simply iboga is a perennial rainforest shrub and psychedelic, 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. A small amount of ibogaine, along with precursors of ibogaine, are found in "Voacanga africana".
Tasmannia Tasmannia is a genus of woody, evergreen flowering plants of the family Winteraceae. The 40 species of "Tasmannia" are native to Australia, New Guinea, Sulawesi, Borneo, and the Philippines. The Winteraceae are magnoliids, and are associated with the humid Antarctic flora of the Southern Hemisphere. The members of the family generally have aromatic bark and leaves, and some are used to extract essential oils. The peppery-flavored fruits and leaves (especially dried) of this genus are increasingly used as a condiment in Australia. The peppery flavour can be attributed to polygodial.
