Muira Puama
An Amazonian tonic traditionally used to support energy and sexual vitality.
Muira Puama (Ptychopetalum olacoides) is a shrub native to the Brazilian Amazon whose root and bark have been used traditionally by indigenous communities as a tonic. In folk and herbal medicine it is commonly cited for antifatigue effects and as an aphrodisiac or stimulant, and has a history of use for neuromuscular complaints and general debility.
Available as powdered extracts, tinctures and dried plant material, muira puama contains compounds such as muirapuamine, tannins and various triterpenes. Some clinical studies have evaluated standardized extracts — often near 1500 mg daily in trials addressing sexual function — but evidence is limited and results vary by individual. Reported precautions include avoidance in pregnancy, lactation and children, and caution for people taking central nervous system or steroid-related medications; infrequent adverse effects reported include insomnia, agitation and occasional respiratory or skin reactions. Consult a healthcare professional for personalized advice.

Origin & History
Muira puama is a shrub native to the Brazilian Amazon, occurring mainly in sandy and clay soils and producing small white flowers with a jasmine-like scent. The root and bark are the parts most commonly harvested; both are described in traditional sources as slightly pink and are used in local herbal preparations.
Indigenous Amazonian communities traditionally used muira puama root and bark as a restorative tonic to counter fatigue and physical debility. Historically it has been applied in the region for neuromuscular complaints, rheumatism, flu and astenia, and its extracts later entered wider herbal use abroad for tonic and digestive purposes; in contemporary herbal practice it is often cited for tonic and aphrodisiac uses. Uses and effects may vary by individual.
Composition & Active Compounds
Muira puama is a shrub up to 5–8 metres tall with white, jasmine-scented flowers; the roots and bark are slightly pink and are the parts most commonly harvested for herbal use. Its chemical profile comprises a mix of alkaloids, tannins, terpenes, esters, volatile oils and other phytochemicals that help explain its traditional applications and make it a subject of phytochemical research. The root and bark are the primary parts used in supplements, and muirapuamina together with tannins are considered key constituents.
- Muirapuamina: an alkaloid cited as a principal active compound and of interest in research related to the plant’s traditional uses
- Flobafenos: pigments formed by oxidation of tannins; contribute to coloration and phytochemical complexity
- Alpha- and beta-resinic acids: resinic acids present among the plant’s acidic constituents
- Behenic acid (esters): part of the plant’s ester fraction and fatty acid profile
- Lupeol: a triterpene commonly found in plant resins and triterpenoid fractions
- Sterols: plant sterols present in the lipid fraction
- Tannins: polyphenolic compounds contributing astringency and potential antioxidant activity
- Coumarins: benzopyrone-type compounds reported in the composition
- Monoterpenes: volatile aromatic compounds contributing to the plant’s scent
- Triterpenoids: diverse terpenoid compounds including lupeol
- Volatile oils: essential oil components responsible for aroma
- Fatty acids: various long-chain fatty acids found in roots and bark
- Chromium: trace element reported among the plant’s micronutrient content
