Therapeutic Uses, Benefits and Claims of Muira Puama

Traditionally this herb was used by indigenous tribes as an aphrodisiac and to treat impotence. Chewing the barks, stems or root was the most popular method of administration.
Muira puama has also been used as a tonic for nervous conditions and depressions. It has been used to promote overall nerve function and to relieve nerve pain.
Some Amazonian tribes have used this medicinal herb to treat dysentery and rheumatism. A paste of the bark and/or root oils has also been applied topically to treat beriberi and paralysis.
In Europe, around 1930, it became a popular supplement for treating erectile dysfunction. It has been shown to be as effective as yohimbine in some cases, without the adverse side effects.
Although clinical studies and research are sparse, muira puama is still promoted today as a treatment for erectile dysfunction and as a male aphrodisiac.
It has also been used for gastrointestinal disorders and as a treatment for indigestion.
Muira puama does have a stimulant effect that leaves the user with a general feeling of well-being when taken in proper doses. Large doses may cause an overstimulation leaving the user feeling restless and affecting sleep.
This herbal supplement has also been shown, in animal studies, to improve mental focus and clarity. It may also help improve concentration and short-term memory.
It is also used to naturally treat hair loss.
Its stimulant effect also makes it useful as an herb for depression.

Muira puama can be combined with other herbs, such as damiana, guarana, catuaba, and suma, to increase its effects.
