Yohimbine, also known as quebrachine, is an indole alkaloid derived from the bark of the African tree Pausinystalia johimbe (yohimbe) and from the bark of the unrelated South American tree Aspidosperma quebracho-blanco. It is a veterinary drug used to reverse xylazine.

Substances purported to be extracts from the yohimbe tree have been marketed as dietary supplements for various purposes, especially for erectile dysfunction, but they contain highly variable amounts of yohimbine, if any; no published clinical evidence supports their efficacy for treating sexual dysfunction or any disease.
