Proposed Uses: Male Sexual Dysfunction; Enhancing Mental Function

Muira puama is a bush native to the Brazilian Amazon rain forest. Its bark and roots have been used traditionally for a variety of medicinal purposes. Explorers brought muira puama to Europe, where it became popular primarily as a treatment for impotence. However, there has been no reliable scientific evaluation of the effectiveness of this herb.

One study is commonly cited as showing that muira puama is more effective for impotence than the drug yohimbine. However, this study actually shows nothing at all. It was an open trial, in which all participants took muira puama. The researchers simply compared the benefits seen in this trial to the benefits seen in other trials in which people took yohimbine. From a scientific perspective, this is of limited usefulness.

Weak evidence hints that muira puama may be helpful for enhancing mental function by increasing brain levels of acetylcholine, but this evidence is far too preliminary to indicate effectiveness.

Dosage
Muira puama is generally taken in the form of a liquid alcohol extract. Follow label instructions for dosage.

Safety Issues
From what limited evidence that is available, it does not appear that use of muira puama commonly causes significant side effects. However, comprehensive formal safety evaluation has not been conducted. For this reason, muira puama should not be used by pregnant or nursing women, young children, or individuals with severe liver or kidney disease.

The Fountain of Youth?

And, if you are already experiencing the ill effects of aging, what if I told you that it may be possible for you to look and feel 20 years younger and stay that way beyond the age of 100.

Aside from the fact that you'd probably call me crazy, I have to tell you that we have never been as close as we are today to actually being able to extend human life!
