Yohimbine

Yohimbine is an alkaloid with stimulant and aphrodisiac effects found naturally in Pausinystalia yohimbe (Yohimbe). It is also found naturally in Rauwolfia serpentina (Indian Snakeroot), Alchornea floribunda (Niando), along with several other active alkaloids. Yohimbine has been used as both an over-the-counter dietary supplement in herbal extract form and prescription medicine in pure form for the treatment of sexual dysfunction. Yohimbine was explored as a remedy for type 2 diabetes in animal and human models carrying polymorphisms of the α_2A-adrenergic receptor gene.
