Yohimbe is the name of an evergreen tree that is found in Zaire, Cameroon, and Gabon. The bark of yohimbe contains a chemical called yohimbine, which is used to make medicine.
Yohimbe is used to arouse sexual excitement, for erectile dysfunction (ED), sexual problems caused by medications for depression called selective-serotonin reuptake inhibitors (SSRIs), and general sexual problems in both men and women. It is also used for athletic performance, weight loss, exhaustion, chest pain, high blood pressure, low blood pressure that occurs when standing up, diabetic nerve pain, and for depression along with certain other medications.
How does it work?
Yohimbe contains a chemical called yohimbine which can increase blood flow and nerve impulses to the penis or vagina. It also helps counteract the sexual side effects of certain medications used for depression.
