Yohimbine (/joʊˈhɪmbiːn/) is an indole alkaloid derived from the bark of the Pausinystalia yohimbe tree in Central Africa. It is a veterinary drug used to reverse sedation in dogs and deer. Yohimbine has been studied as a potential treatment for erectile dysfunction but there is insufficient evidence to rate its effectiveness. Extracts from yohimbe have been marketed as dietary supplements for improving sexual function.
