Horny Goat Weed: Will it make you excited, too?
Epimedium is a pungent ornamental herb found in Asia and the Mediterranean. The Chinese call it Yin Yang Huo, which loosely means "licentious goat plant." Legend has it that the name horny goat weed came from a herder who noticed his goats becoming more sexually active after eating the plant. Supplement companies have adopted the provocative name by which it is known in the U.S. Horny goat weed was named epimedium because it is similar to a plant found in the ancient Asian kingdom of Media, now a part of Iran. Epimedium is a genus of many related plant species and some are used for medicinal purposes, including Epimedium sagittatum, Epimedium brevicornum, and Epimedium koreanum.

Laboratory trials
Effects of icariin on cGMP-specific PDE5 and cAMP-specific PDE4 activities.
Xin ZC. The 1st Hospital, Peking University, 8 Xishiku Street, Xicheng District, Beijing
Zhonghua Yi Xue Za Zhi. 2004.
To clarify the mechanism of the therapeutic action of icariin on erectile dysfunction (ED). PDE5 was isolated from the human platelet and PDE4 from the rat liver tissue. The inhibitory effects of icariin on PDE5 and PDE4 activities were investigated. Papaverine served as the control drug. Icariin and papaverine showed dose-dependent inhibitory effects on PDE5 and PDE4 activities. The IC(50) of Icariin and papaverine on PDE5 were 0.432 micromol/L and 0.680 micromol/L, respectively and those on PDE4, 73 micromol/L and 3 micromol/L, respectively. The potencies of selectivity of icariin and papaverine on PDE5 (PDE4/PDE5 of IC(50)) were 167 times and 4 times, respectively. Icariin is a cGMP-specific PDE5 inhibitor that may be developed into an oral effective agent for the treatment of ED.
