Yohimbine is an aphrodisiac obtained from the bark of a tropical West-African tree.
Research has shown that it enhances erections and probably also increases sexual desire.
Traditionally the bark is boiled in water, making it into a real love potion. In the Netherlands yohimbine is a prescription drug used to treat erection problems.
Yohimbine may work instantly, but it can also take two months before a guy experiences any improvement in his condition. On some guys it has no effect whatsoever.
It can have some innocent but bad side effects, like excessive sweating, increased blood pressure, heart rate increase, anxiety, headaches, dizziness, panic attacks and hallucinations.
