Yohimbine synonym quebrachine, and not to be confused with yohimbe, is a Indoloquinolizidine alkaloid derived from the bark of the African tree Pausinystalia johimbe; also from the bark of the unrelated South American tree Aspidosperma quebracho-blanco. Yohimbine is an alpha-2 adrenergic antagonist, and has been used in a variety of research projects. It is a veterinary drug used to reverse sedation in dogs and deer. While yohimbine behaves as an aphrodisiac in some mammals, it does not do so in humans. It has been prescribed as a treatment for erectile dysfunction, but its reported clinical benefits were modest and it has largely been superseded by the PDE5 inhibitor class of drugs. Substances which have purported to be extracts from the yohimbe tree have been marketed as dietary supplements for various purposes, but they contain highly variable amounts of yohimbine, if any; no published scientific evidence supports their efficacy.
