Yohimbe bark (Yohembe bark)- A Natural Cure for Impotence and to help with better, firmer Erections.

Yohimbe Bark Extract is the only alternative impotence treatment to have received FDA approval.
Yohimbe was discovered in South Africa, and was originally used as an aphrodisiac. The active compound in yohimbe bark - yohimbine - helps dilate small blood vessels, Men given yohimbine injections have been reported to experience immediate penal firmness. It isn't yet known how it works, but the success rate is considered quite solid. Many men do report it helping.  Strong Yohimbe bark extract can interfere with sleep and cause rapid heart beat and other "caffeine" style responsese. However, the yohembe bark that is sold and purchased over the counter is not as potent and those side effects are rarely reported if the directions are followed. The amount of active ingredient- yohimbinine- can vary, so start with a lower dose when trying a new brand.
