Iboga Overview
Iboga is a shrub native to Central and West Africa that has been used in traditional medicine and spiritual practices. Its root bark contains a number of alkaloids, including ibogaine, which has hallucinogenic and stimulant properties. Iboga has been studied in regard to its use in those suffering from alcohol and drug addiction, but the main constituent of Iboga (ibogaine) is a schedule I controlled substance in the United States, and possession is illegal. Its use as a traditional medicine is generally not recommended due to safety concerns.
