Botanical Overview
Iboga (Tabernanthe iboga) belongs to the Apocynaceae family. While not among the most extensively documented medicinal plants, this species has recorded uses that warrant attention from researchers and practitioners. The dogbane family (Apocynaceae) includes herbs, shrubs, vines, and trees with milky sap containing alkaloids and cardiac glycosides. The flowers are typically five-petaled and often showy with a tubular corolla. Many species in this family are highly toxic but also source of important cardiac medications.
