Background
- Indole alkylamine from West African Yohimbine tree (Corynanthe yohimbe)

- Extracts from yohimbe have been used in traditional medicine in West Africa as an aphrodisiac and have been marketed in developed countries as dietary supplements.
- α2-adrenergic antagonist with cholinergic activity[1]
- Commonly used for treating erectile dysfunction. Also, for other uses (eg, postural hypotension); marketed as athletic performance enhancers, dieting agent.

- Mydriasis
- Nausea, vomiting, salivation
- Anxiety
- Large ingestions may cause mania, bronchospasm, lupus-like syndrome
