The concoction touted as Power V, an "Herbal Viagra" (without the side effects), has shown it can prevent impotence and extend erections in laboratory animals. The study, featured in this month's Journal of Scientific Oriental Medicine, showed that the Herb mixture from Power V, based on an ancient Chinese formula, achieved "significant results" giving a measure of scientific support to the popular product known as Power V.

In the study, the laboratory animals were fed a high-cholesterol diet and injected with chemical agents that impede the blood circulation, making them impotent. Three months into the six-month study, the Herbal mixture from Power V was blended into the food of half the study. As predicted, the other half who continued to be fed just the high-cholesterol diet indeed ended up with high cholesterol levels and 100% became impotent. But those that ingested with Power V Herbal mixture were later able to have sustained erections.

The results of the study are still preliminary, says Dr. Yu K. Chen. Afterall, "this pilot research is designed to set the foundation to extrapolate more finding when compared with human clinical trials."

However, the Herbal ingredients in Power V contained natural hormones and nutrients critical in good penile functioning. It increased blood circulation and promoted nitric oxide to help achieve erections. It also helped to maintain the increased blood flow to the sexual organ, making longer and harder erections.

In another study of 45 men in the U.S., 75% reported improvements in sexual functioning and urinary control after two months of regular use.

In the end, although studies were preliminary, the Power V Herbal mixture successfully treated the symptoms of Erectile Dysfunction and even promoted growth and longevity to erections.
