Horny goat weed , or epimedium (a.k.a. yin yang huo, “yang tonic”), is a small leafy shrub native to China and Japan. Growing wild in mostly high altitude areas, epimedium has been used in traditional Chinese medicine for over 2,000 years.
Epimedium is purported to stimulate production of androgens (sex hormones) and suppress the production of the stress hormone cortisol, which in turn is said to help boost sexual function in both men and women.
Horny goat weed is prescribed in Chinese medicine to help improve erectile dysfunction in men, and enhance libido in both men and women. Individuals who use horny goat weed report an overall sense of well-being and relief of fatigue. It is also reported to be useful in relieving unpleasant symptoms of menopause, and improving exercise recovery.
At present, there is little solid scientific research available to back these claims.
General recommended dosage: 250-1000 mg/day in 2-3 divided doses
Horny goat weed (epimedium) is available in capsule and herb form.
It is reported that the most effective Horny goat weed supplements are standardized to contain at least 10% of the flavanoid icarrin (also spelled icariin).
Variations in product quality and formulation may impact effectiveness. Traditional Chinese medicine usually prescribes epimedium in herbal tea form.
