Overview
Epimedium, a genus of flowering plants in the Berberidaceae family, is widely recognized in traditional Chinese medicine (TCM) for its therapeutic properties. Commonly referred to as Horny Goat Weed, it derives its name from its historical use as an aphrodisiac. The plant is native to China, Korea, and Japan, where it thrives in shady, forested areas. The primary bioactive compound in Epimedium is icariin, a flavonoid glycoside studied for its potential effects on cardiovascular health, bone density, and sexual function. Modern applications extend to dietary supplements and herbal extracts, making it a valuable commodity in the B2B botanical market.
Physical and Chemical Properties
Epimedium is typically harvested as dried leaves or processed into powdered extracts. The color ranges from light brown to yellow, depending on processing methods. Icariin, its key active ingredient, has a molecular formula of C33H40O15 and a molecular weight of 676.66 g/mol. The compound is soluble in ethanol and partially soluble in water, which influences extraction techniques. Epimedium extracts often standardize icariin content (10%-60%) to ensure consistency for commercial use. Stability is maintained in cool, dry conditions, though prolonged exposure to moisture or heat may degrade active compounds.
Main Applications
In TCM, Epimedium is prescribed to support kidney function, alleviate fatigue, and address sexual dysfunction. Its adaptogenic properties make it popular in energy-boosting formulations. Beyond traditional uses, icariin is researched for its potential to enhance osteoblast activity, suggesting applications in osteoporosis management. The supplement industry incorporates Epimedium into capsules, tinctures, and teas, often marketed for vitality and hormonal balance. B2B buyers should note regional regulations, as some countries restrict claims related to its aphrodisiac effects. Quality assurance, including third-party testing for heavy metals and pesticides, is critical for compliance.
Safety and Storage
Epimedium is generally considered safe at recommended doses, though excessive consumption may cause dizziness or dry mouth. Contraindications include use with anticoagulants or by individuals with hormone-sensitive conditions. Suppliers should provide material safety data sheets (MSDS) for bulk purchases. Proper storage involves sealing dried leaves or extracts in moisture-proof containers, ideally at temperatures below 25°C (77°F). Shelf life varies: powdered extracts last up to two years, while whole leaves may degrade faster. Buyers should prioritize suppliers with climate-controlled warehouses to prevent spoilage.
B2B Procurement Guide
When sourcing Epimedium, verify the icariin concentration, which directly impacts potency and pricing. Organic certification and non-GMO status add value for premium markets. Reliable suppliers often provide HPLC (High-Performance Liquid Chromatography) reports to confirm purity. Bulk pricing varies by order volume and extraction method (e.g., water vs. ethanol). For reference, 1 kg of 20% icariin extract may cost $50-$100, while raw leaves are cheaper but require further processing. Establish long-term contracts with trusted growers to mitigate seasonal supply fluctuations.
