What is an Aphrodisiac?
Yohimbine is the main alkaloid of Yohimbe. Yohimbe, but not Yohimbine, is often popularly referred to as a "weak MAO inhibitor" although no sources are cited for this. Pharmaceutical preparations of yohimbine do not indicate that the drug, which is approved in the US for treatment of impotence (under such brand names as Yocon,Yohimex, Aphrodyne and Viritab), is an MAO inhibitor. Its main action is as an alpha-adrenergic antagonist, by which yohimbine may increase genital bloodflow and both sexual sensitivity and excitation in some people. Preparations of yohimbe bark are available over-the-counter and should be used with caution. The unrefined yohimbe bark contains several active alkaloids besides yohimbine. Side effects can include rapid pulse, sweating, and anxiety reactions in susceptible people. Pharmaceutical preparations of yohimbine can also produce these side effects at higher doses, but are available in standardized doses which allow the patient to dose in a controlled fashion. Some patients report a cumulative prosexual effect using the drug over time.
