Eurycoma Longifolia is a shrub native of Indonesia and Malaysia whose bark and roots are commonly used as an aphrodisiac for men. On the other hand, because it is an "alternative" medication, there is limited research (especially in humans) as to the herb's short- and long-term effects.
Uses
In studies of male mice, Eurycoma longifolia has been found to protect against malaria, ulcers and some kinds of tumors. It can also lower levels of sugar in the blood and decrease overall anxiety. However, its main use in humans is as an aphrodisiac. Although that particular effect of the herb has not been well researched on humans, it has shown an "aphrodisiac" effect in mice. It causes growth of portions of the prostate as well as of the seminal vesicles, both of which are indicators of male arousal.
Side Effects (Mice)
Much of the work on Eurycoma longifolia has been done in animal studies. In the studies examining the herb's anti-malarial properties, doses of the medication that were sufficient to inhibit malaria also caused the animals to die prematurely. In mice, a dose of approximately one half of a gram of Eurycoma longifolia per kilogram of mouse body weight caused increased liver, spleen, kidney and testicle weight, eventually leading to death of the mice. Higher doses caused convulsions, shallow breathing and depression as well as sudden death.
Human Side Effects
Unfortunately, there is insufficient data to properly analyze either the effectiveness or the side effects of this medication in humans. As a result, it is difficult to determine the dosing or side effects, though it can be assumed that high levels can be toxic. Consequently, it is not recommended that humans take more than one gram of this medication per day.
