Modern Evidence

Muira puama has a tradition as a vitality, energy, and libido tonic; preclinical and small studies are limited and marketing claims outpace evidence. Clinical evidence is insufficient; it is not a treatment for erectile dysfunction, fatigue, depression, or any disease, though it remains a valued Amazonian tonic cup.
