The Chinese refer to epimedium as "yin yang huo", which has been loosely translated by some as "licentious goat plant" and explains why Western supplement companies have adopted the titillating name by which it is known in the U. S: (horny goat weed). Epimedium is grown as an ornamental herb in Asia and the Mediterranean region, and various species are used for medicinal purposes, including Epimedium sagittatum, Epimedium brevicornum, Epimedium wushanense, Epimedium koreanum, and Epimedium pubescens. The use of epimedium as a medicinal herb dates back to at least 400 A. D., where it has been used as a tonic for the reproductive system (boosting libido and treating impotence) and as a rejuvenating tonic (to relieve fatigue). Epimedium is thought to work via modulation of cortisol levels (the primary stress hormone). Under conditions of high stress, the increased cortisol levels are known to cause fatigue and depress sex drive - so bringing cortisol levels back into normal ranges is also thought to help restore normal metabolism, energy levels and libido.
