Herbal Vigor contains Epimedium Sagittum –

Safe, Effective, and Natural Sexual Enhancement.

Epimedium Sagittum is a traditional botanical medicine used in China and Japan. Although this herb (which also goes by the names Yin Yang Huo, Inyokaku, and Herba Epimedii, Horny Goat Weed) has a history of traditional use for disorders of the kidneys, joints, liver, back and knees, its principle use is as an aphrodisiac.

According to one herbal author, Epimedium Sagittum has testosterone-like effects. It stimulates sexual activity in both men and women, increases sperm production, stimulates the sensory nerves, and increases sexual desire. Epimedium Sagittum’s aphrodisiac effects has been verified in both animal and human research. Mice treated with a Epimedium Sagittum preparation produced “apparent effects on the improvement of sexuality. It was also shown to improve sperm producing capability. Since Epimedium Sagittum has been traditionally used for kidney disease, it’s interesting that research has demonstrated a sexual potentiation effect and improved quality of life in patients with chronic renal failure who were given Epimedium Sagittum.

Research has shown that Epimedium Sagittum significantly increases testosterone in mice. This certainly appears to be the herb’s mechanism of action, although Epimedium Sagittum may have more than one. For example, it has been established that sexual arousal is linked to the activity of cholinergic neurotransmitters. However, an enzyme called acetylcholinesterase (AChE) inactivates cholinergic neurotransmitters within 1/500 of a second. As it turns out, research shows that Epimedium Sagittum 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 Epimedium Sagittum has anti-fatigue effects and helps prevents adrenal exhaustion.
