Yohimbe bark powder, a supplement derived from the West African Yohimbe tree, is a popular natural treatment for erectile dysfunction. While users of the supplement should take note of the manufacturer's recommendation for dosing, a general guideline for safety is about 15 to 30 milligrams a day.

On the Other: FDA Recommendations

According to a 1994 report published in The American Journal of Natural Medicine, Yohimbe bark has proven to be moderately successful in treating erectile dysfunction. Still, the FDA (U.S. Food and Drug Administration) says that while "crude" yohimbe bark preparations (like powder) are available, consumers should use pure yohimbine hydrochloride. In fact, the FDA classifies yohimbe as an unsafe herb since the actual amount of yohimbe is virtually impossible to detect in such preparations.

Bottom Line

Consider the side effects of yohimbe bark powder before starting a regimen. Side effects of yohimbe bark are a cause for concern for many people. Those with high blood pressure or hypertension shouldn't use yohimbe bark as it may elevate blood pressure and heart rate. Yohimbe can cause hallucinations, anxiety and panic attacks in some people. Other side effects include various skin irritations, headache and dizziness. Check with your doctor before starting any new medicines or supplements to ensure that it's safe for you to do so.
