Icariin
The active compound in horny goat weed, known for its aphrodisiac effects.
Also known as: Horny Goat Weed Extract
Overview
Icariin is the primary active compound found in plants of the Epimedium genus, most notably Horny Goat Weed. It is a flavonoid compound that has been traditionally used in Chinese medicine to enhance libido and treat erectile dysfunction. Icariin is believed to work by inhibiting the enzyme PDE5, which is the same mechanism of action as prescription drugs like sildenafil. By inhibiting PDE5, icariin can increase blood flow to the penis, resulting in improved erections. In addition to its effects on sexual health, icariin is also being studied for its potential to improve bone health, protect the brain, and reduce inflammation.
