Overview

Eurycoma longifolia is a tall evergreen shrub-tree commonly found in Southeast Asia. It's a protected species with a history of use as an aphrodisiac.

The root of Eurycoma longifolia contains several chemicals that have different effects in the body. Some of the chemicals seem to affect how the body produces the hormone testosterone and might increase testosterone levels in the body.

Eurycoma longifolia is used for erectile dysfunction (ED), male infertility, increasing sexual desire in healthy people, and boosting athletic performance, but there's no good scientific evidence to support most of these uses.
