Weed is a traditional medicine used in China and Japan. Although this
herb (which also goes by the manes of Yin Yang Huo, Inyokau, and Herb
Epimedii) has a history of traditional uses for disorders of the
kidneys, joints, liver, back and knees, its principle use is as an
aphrodisiac. According to one herbal author, Horny Goat Weed has
testosterone-like effects, it stimulates sexual activity in both men and
women, increases sperm production, stimulates the sensory nerves, and
increases sexual desire.
Horny Goat Weed's aphrodisiac effects have been verified in both animal
and human research. Mice treated with a Horny Goat Weed preparation
produced "apparent effects on the improvement of sexuality." It has also
shown to improve sperm producing capability. Since Horny Goat Weed has
been traditionally used for kidney disease, it's interesting that
research ahs demonstrated a sexual potentiation effect and improved
quality of life in patients with chronic renal failure who were given
Horny Goat Weed.
Mechanisms of Action
Research has shown that Horny Goat Weed significantly increases
testosterone in mice. This certainly appears to be the herb's mechanism
of action, although Horny Goat Weed may have more than one. For example,
it has been established that sexual arousal is linked to activity of
cholinergic neurotransmitters. However, an enzyme called
acetyl-cholinesterase (AchE) inactivates cholinergic neurotransmitters
within 1/500 of a second. As it turns out, research shows that Horny
Goat Weed is capable of inhibiting AchE. Such an inhibition may support
higher levels of the key cholinergic neurotransmitters associated with
sexual arousal. In addition, research has shown that Horny Goat Weed has
anti-fatigue effects and helps prevent adrenal exhaustion.
