Muira puama (Ptychopetalum olacoides) is a small tree native to the Amazon rainforest in Brazil and other parts of South America. Its root and bark have been used for centuries by indigenous peoples as a tonic for sexual health, nerve function, and general vitality. Today it is widely available as an herbal extract and is sometimes called 'potency wood' for its traditional reputation as a natural aphrodisiac.

Muira puama appears to support sexual function partly by acting on the nervous system — helping to enhance nerve signaling involved in sexual arousal and desire. It may also have a mild influence on hormone regulation and circulation in pelvic tissues. Some of its plant compounds interact with acetylcholine pathways in the brain, which connects to both mood and sexual motivation.

The most studied and traditionally used forms are alcohol-based liquid extracts (tinctures) and standardized root/bark capsules. Tinctures allow faster absorption; capsules offer convenience and easier dosing. Powder forms can be mixed into drinks but are less commonly standardized. Look for products specifying root or bark extract, as leaf preparations are not traditional and less researched.

Muira puama is a rainforest plant extract not found in common foods. To support the same goals — sexual vitality, nerve health, and energy — focus on foods rich in zinc (oysters, pumpkin seeds, beef), which supports testosterone production; healthy fats (avocado, olive oil, oily fish), which are building blocks for sex hormones; and dark leafy greens and beets for nitric oxide support and circulation. Reducing alcohol and ultra-processed foods also supports the hormonal and nerve health that muira puama targets.
