What is it used for?
The promotion of muira puama as a male sexual stimulant or as a treatment for erectile dysfunction can be traced back to the 1930s in Europe, but its popularity has increased with the success of Viagra (sildenafil) and the promotion of herbal sildenafil preparations. It is also an ingredient of the popular Brazilian herbal tonic Catuama, consisting of guarana, ginger, Trichilia catigua, and P. olacoides. The stems and roots of P. olacoides have been used as a tonic for nerve and muscle problems. A root mixture is used externally in massages and baths for paralysis and beriberi (disease in which the body does not have enough thiamine [vitamin B1]). Tea made from the roots has been used for erectile dysfunction, rheumatism, and GI problems.
Clinical evidence to support the effects of P. olacoides on sexual dysfunction is limited. More focus is now on potential use in Alzheimer or similar conditions of mental decline. Studies in rodents demonstrated improved memory and reversal of mental impairment; however, clinical trials are limited.
