Epimedium herb or, as it is known throughout the herbal marketplace "Horny Goat Weed" is a small ground bearing shrub with broad heart shaped leaves that resemble ground ivy. Commonly found in Asian medical communities and street side markets, it is often referred as a "Yang Tonic" producing a warm almost euphoric effect on the body. Not much study has been documented and because of recent popularity we can expect more investigation and coverage of this unique botanical. Epimedium is commonly used as an aphrodisiac and assists in relieving sexual dysfunction in both men and women.
