Botanical Overview
Four-Leaf Devilpepper (Rauvolfia tetraphylla) 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.
General Description

Rauvolfia tetraphylla fruits are called devil-peppers and hold an important position in the Indian traditional system of medicine. The plant has various significances and it is widely used by South Indian tribes. Asima Chatterjee initiated chemical investigation of alkaloids in Rauvolfia tetraphylla then known as Rauwolfia canescens. Indole alkaloids including serpentine, reserpine, serpentinine, and other Rauwolfia alkaloids were identified in phytochemical study.
