What is Yohimbe?


Yohimbe is an evergreen tree that grows in western Africa in Nigeria, Cameroon, the Congo and Gabon. The bark of the tree contains the active compounds called alkaloids. The principal alkaloid is called yohimbine. It can also be found in high amounts in the South American herb, Quebracho (Aspidosperma quebracho-blanco). Because it is thick and soft, it is relatively easy to remove from the tree trunk and branches. While yohimbe bark may be harvested anytime during the year, its alkaloid content is highest during the rainy, winter season which is between May and September in the Southern Hemisphere.Yohimbe contains a complex mixture of compounds including alkaloids as well as some tannin.
Most of the herb's effects are thought to be due to yohimbine, although reserpinoid alkaloids and other chemicals found in the whole herb may modify yohimbine's effects. Yohimbine works by blocking certain types of neurotransmitter-receptors in nerve cells. Yohimbine affects primarily a part of the adrenaline-related or "adrenergic" nervous system, which helps control aspects of various bodily functions, including motor activity and sexuality. Yohimbine is thought to have a relatively minor effect on adrenaline, the hormone that stimulates the heart and temporarily increases muscular strength.
