Also called “Horny Goat Weed” for good reason. Epimedium is a plant that comes from the botanical family, “Berberidaceae.” The Epimedium plant is said to contain certain chemical compounds, otherwise known as flavonoids that have antioxidant properties. It also contains phytoestrogens, which have effects similar to estrogen. This phytoestrogen, known as epimedium icariin, blocks an enzyme in the body using a natural pathway. Epimedium icariin aids the body in the transport of nitric oxide that encourages your body to increase the production of testosterone.
