Many species of Epimedium are reported to have aphrodisiac qualities. According to legend, this property was discovered by a Chinese goat herder who noticed sexual activity in his flock after they ate the weed.

Horny Goat Weed is purported to work by increasing levels of nitric oxide, which relax smooth muscle. Horny Goat Weed has been demonstrated to relax rabbit penile tissue by nitric oxide and PDE-5 activity [1]. Other research has demonstrated that injections of Epimedium extract, directly into the penis of the rat results in an increase in penile blood pressure.[2] R-phrases , , , , S-phrases , , , Supplementary data page Structure and properties n, εr, etc. ...

Many species, hybrids, and cultivars are grown for ornamental specimens and for use in the woodland garden. They can also serve as attractive ground cover for partially shaded areas. The evergreen species are particularly good at keeping down weeds; the deciduous ones often have attractively colored new foliage in spring. One of the more popular cultivars is the Persian barrenwort E. x versicolor 'Sulphureum', also known as the Bicolor barrenwort, which produces soft yellow flowers in the spring. This plant is very tough and adaptable, being drought-tolerant in shaded to partly shaded conditions when established; it is a hybrid of E. grandiflorum x E. pinnatum ssp. colchicum.

Horny Goat Weed (Epimedium) Supplement Review (782 words)
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.
Animal studies have shown that epimedium may function a bit like an adaptogen (such as cordyceps, rhodiola, ashwagandha, and ginseng) by increasing levels of epinephrine, norepinephrine, serotonin, and dopamine when they are low (an energy-promoting effect), but reducing cortisol levels when they are elevated (an anti-stress effect).
Animal studies using epimedium have shown a reduction in bone breakdown, an increase in muscle mass, and a loss of body fat-each of which may be linked to the observed return of abnormal cortisol levels back to normal values (and rhythm).
