Horny Goat Weed, derived from plants in the Epimedium genus, has a long history in traditional Chinese medicine and has drawn modern scientific interest for its active compound icariin. Research suggests that icariin may support bone density by influencing osteoblast activity, which has made it a subject of study in bone and joint health contexts. Studies also indicate potential benefits for sexual function, as icariin appears to act on pathways similar to those targeted by conventional erectile dysfunction medications, though human clinical trials remain limited. Additionally, preliminary research has explored its role in reducing fatigue and supporting energy levels. Most available extracts are standardized to icariin content, but the overall evidence base is still developing, and more rigorous human studies are needed to confirm these early findings.
