Yohimbine works by widening blood vessels and increasing blood flow in the body. It is also thought to increase fatty acid mobilization. Yohimbe stimulates the central nervous system by causing the body to produce more noradrenaline. Its popularity has been ignited not only by its claimed effects to elevate libido but also by new research that shows it could be an herb with very effective antioxidant potential. Nitric Oxide levels also increase which can dilate blood vessels and can potentially allow for increased blood flow. The combination of both increased blood flow and energy contributes to yohimbine HCL's effectiveness to help maintain a healthy heart, but Yohimbine also has been shown to decrease fat synthesis in the body by increasing fatty acid mobilization.
