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 bodybuilders 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.
