Horny goat weed is a specie of epimedium. It’s long ago that a Chinese boy noticed his male goat suddently became horny and made love with many female goats that appeared that it had a very strong sexual ability. So the boy began to observe what happen to the male goat and finally he found the male goat became horny after eatting a leafy plant. He tested this plant to make other male goats to eat it and the same phenomenon happened again. Form then on, people realized that this leafy plant is a herbal aphrodisiac and named it “Horny goat weed”, known as Chinese “Yin Yang Huo”.
Recently, people studied it by scientic analysis and found there a active molecule called Icariin in horny goat weed extract. Icariin inhibits the activity of PDE5. PDE5 is a protein in the smooth muscle cells of the penis to , erections become more possible when the activity of PDE5 is inhibited. This is the ame biological process of Viagra. Of course horny goat weed is as potent as Viagra, but we can see it really enhances the sex ability. Another benefit to sex of this plant is that it can increase the nitric oxide produced inside human body, the nitric oxide can help blood move through the circulatory system to make erections easier.
Horny goat weed can work independently to enhance the sex ability and improve libido, and some people report that it worked better in combination with other herbal aphrodisiacs. I think it depends on your personal body situations, you can try it alone or use it in a combination with other herbs.
