Yohimbine is a natural supplement derived from the bark of an African tree, Pausinystalia yohimbe. It is used to treat a variety of medical conditions, including erectile dysfunction, anxiety, and obesity. Yohimbine works by increasing the release of norepinephrine, a hormone that helps to regulate heart rate and blood pressure. It can also increase the release of dopamine, a neurotransmitter that helps to regulate mood and motivation. However, yohimbine may cause side effects such as headache, nausea, and dizziness and should be used cautiously.
