Description
Commonly known as Horny Goat Weed, this herb is used in the United States mainly for its aphrodisiac properties and libido enhancement in men and women. It is sometimes combined in natural aphrodisiac products with other herbs used for sexual enhancement including avena sativa, catuaba, eurycoma, yohimbe, tribulus terrestris, mucuna pruriens, muira puama, maca, ginsent, ginkgo biloba, and others. Herbal Epimedium species have been used widely in Traditional Chinese Medicine for sexual enhancement, immunity improvement, anti-cancer and anti-aging treatment. Flavonoids and polysaccharides are the major active components.
The botanical name for horny goat weed is Epimedium sagittatum. There are many varieties of plants, including grandiflorum. Epimedium herb Yinyanghuo, one of the popular Chinese materia medica, is a multiple species colony of Epimedium genus belonging to Berberidaceae. There are five species that have been officially adopted in Chinese Pharmacopoeia under the same crude drug name Yinyanghuo comprising E. brevicornu, E. koreanum, E. sagittatum, E. pubescens, and E. wushanense. In addition, non-official species like E. acuminatum, E. miryanthum and E. leptorrhizum are also mixed and used. Epimedium herb has flavonoids such as icariin, epimedin A, epimedin B, epimedin C and baohuoside Iicariin, along with prenylated flavonol glycosides sagittasine A-C, acylated flavonol glycosides such as kaempferol, together with flavonolignans, 2-phenoxychromones, a lignan, and aromatic acid derivatives. Some of these compounds, particularly icariin, promote endothelial nitric oxide-dependent relaxation of blood vessels and hence can be of help for the treatment of erectile function and impotence.
