Eurycoma Longfolia:
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. This may
demonstrate the anabolic properties of Tongkat Ali many athletes and body
builders now use Tongkat Ali extract as a testosterone-booster, to improve
muscle size, strength, and performance without drugs. Eurycoma longifolia
has become popular for its testosterone-enhancing properties. Historically,
South East Asia has utilized the herb for its suggested antimalarial,
antipyretic, antiulcer, cytotoxic and aphrodisiac properties. Scientific
studies suggest that it enhances sexual characteristics and performance in
animals.
Epimedium Sagittatum (AKA - Horny
Goatweed):
Many species of Epimedium are alleged to have aphrodisiac qualities.
According to legend, this property was discovered by a Chinese goat herder
who noticed sexual activity in his flock after they ate the weed. Like
Viagra, icariin works by increasing levels of nitric oxide, which relax
smooth muscle. It has been demonstrated to relax rabbit penile tissue by
nitric oxide and PDE-5 activity!
Tribulus terrestris:
Tribulus terrestris has long been a constituent in tonics in Indian
ayurveda practice, where it is known by its Sanskrit name, "gokshura." It is
now found to be a booster for the purpose of increasing sex drive. Its use
for this purpose originated in Eastern Europe in the 1970's. Independent
studies have suggested that Tribulus terrestris extract increases hormone
levels, though leaving them in the normal range.
