Hoodia gordonii

Quick Reference

A succulent plant (not a cactus) found in the Kalahari desert. Used in traditional South African herbal medicine as an appetite suppressant and widely marketed as such in the West, although many preparations contain no active components and there is limited evidence for efficacy. The active constituent appears to be an oxypregnane steroidal glycoside, P57AS3 (P57).
