...Eurycoma longifolia has become popular for its alleged testosterone-enhancing properties. It has therefore been included in some herbal supplements for bodybuilders. Historically, South East Asia has utilised the herb for its suggested antimalarial, antipyretic, antiulcer, cytotoxic and aphrodisiac properties...
http://en.wikipedia.org/wiki/Eurycoma_longifoliaSome scientific studies suggest that it enhances sexual characteristics and performance in animals. <1> <2> <3> However, most of these studies were conducted by the same researchers, so more research is needed.
In other studies, fractions of Eurycoma longifolia Jack extract have been shown to induce apoptosis in breast-cancer cells <4> and to be cytotoxic to lung-cancer cells.<5>
The British Journal of Sports Medicine published the results of a scientific study in 2003, which showed that Eurycoma longifolia caused increased muscle strength and size when compared to a placebo.<6> This may demonstrate the anabolic properties of Tongkat Ali but again more research is needed. Some athletes and body builders now use Tongkat Ali extract in the hope that it will act as a testosterone-booster, to improve muscle size, strength, and performance without drugs.
