The Berberidaceae plant Epimedium (Epimedium koreanum) is mainly distributed in China, and its dried leaves are one of the commonly used Chinese medicines in clinical practice. Epimedium has the function of invigorating the kidney and promoting the growth and development of bones. It can inhibit osteoclasts, promote the growth of osteoblasts, protect the cardiovascular and cerebrovascular systems, and increase immune function.
Epimedium Extract is a standardized phytochemical derived from *Epimedium* species, primarily processed via ethanol extraction and chromatography. The core active constituent, icariin (C33H40O15, CAS 489-67-2), defines its potency.
Not approved as a standalone drug; clinical use requires physician supervision. Store in cool, dry conditions below 25°C to prevent icariin degradation. Avoid ingestion by pregnant women due to potential hormonal effects.
