Greenherb supplies a premium, scientifically-validated Epimedium Leaf Extract, derived from the dried leaves of Epimedium brevicornu Maxim. and related species, a revered botanical in Traditional Chinese Medicine known as "Yin Yang Huo" and commonly referred to as Horny Goat Weed. Our epimedium leaf extract is carefully processed from high-quality epimedium leaf material to preserve the full spectrum of bioactive flavonoid glycosides, primarily icariin, along with icariside, epimedin A, B, and C. This potent, standardized epimedium extract powder delivers clinically-supported benefits for male vitality, bone health, libido, and overall energy, offering a time-honored adaptogenic tonic with extensive modern scientific validation for global nutraceutical, dietary supplement, and sports nutrition markets.
We support global B2B customers with consistent quality, scalable supply, and comprehensive analytical documentation, enabling the development of evidence-based products that leverage this legendary Yang-tonifying herb.
Standardized for High-Potency Icariin – Our epimedium leaf extract is precisely standardized to guarantee consistent levels of icariin (typically 5%, 10%, or 20%), the primary bioactive flavonoid responsible for its PDE5-inhibiting, testosterone-supporting, and bone-protective properties. This ensures reliable potency in every batch of epimedium extract .
Clinically-Validated Male Vitality & Libido Support – Icariin and other epimedium flavonoids have been extensively studied for their ability to inhibit phosphodiesterase type 5 (PDE5), promoting healthy blood flow and supporting erectile function. Clinical research demonstrates significant improvements in libido, sexual desire, and performance in men with mild to moderate dysfunction .
Supports Bone Health & Prevention of Bone Loss – Multiple studies show that epimedium leaf extract, particularly its icariin content, helps promote bone formation by increasing osteoblast activity while reducing bone resorption. This makes epimedium powder a valuable ingredient for bone health formulations, especially for postmenopausal women and aging populations .
Natural PDE5 Inhibition with Adaptogenic Benefits – Unlike synthetic PDE5 inhibitors that act acutely, epimedium leaf works through a gentler, adaptogenic mechanism that supports the body's own nitric oxide pathways while also providing antioxidant protection and hormonal balance .
Rich in Unique Flavonoid Glycosides – Beyond icariin, our epimedium extract powder contains epimedin A, B, C, icariside I and II, and other prenylated flavonoid glycosides that work synergistically to support cardiovascular health, neuroprotection, and immune function .
Traditional Yang Tonifying Herb with 2,000+ Years of Use – Epimedium leaf has been used in Traditional Chinese Medicine for over two millennia as a kidney Yang tonic, prescribed for low libido, fatigue, back pain, and joint health. This extensive traditional use provides deep credibility and consumer trust .
Sustainably Sourced from Authentic Growing Regions – Our epimedium leaf is sourced from certified cultivation regions in China (primarily Gansu, Shaanxi, and Sichuan provinces), where the plant thrives in forested mountain areas, ensuring optimal icariin content and sustainable harvesting practices .

Greenherb's Epimedium Leaf Extract harnesses the remarkable Yang-tonifying power of a herb that has been treasured in Traditional Chinese Medicine for over two millennia. Known as "Yin Yang Huo" (literally "licentious goat plant") after the observation that goats consuming it displayed increased sexual activity, epimedium has earned its reputation as a premier botanical for male vitality and reproductive health . Modern science has validated this traditional wisdom, revealing that epimedium's unique prenylated flavonoid glycosides—particularly icariin—act as natural phosphodiesterase type 5 (PDE5) inhibitors, promoting healthy blood flow to support erectile function and libido without the side effects associated with synthetic pharmaceuticals . Beyond its well-known benefits for male vitality, epimedium leaf extract has also demonstrated significant osteoprotective activity, making it one of the few botanicals that simultaneously supports both hormonal health and bone density . Our standardized epimedium extract powder delivers these benefits in a consistent, concentrated form, making it the ideal choice for brands developing advanced products in the male health, bone support, and adaptogenic vitality categories.
Botanical Source: Epimedium brevicornu Maxim., Epimedium sagittatum, Epimedium koreanum, or other related species
Used Part: Dried Leaves
Key Active Components: Icariin, Epimedin A, Epimedin B, Epimedin C, Icariside I, Icariside II, Flavonoids, Polysaccharides .
Standardization: Available standardized to icariin content (5%, 10%, 20%, 50%) or total flavonoid glycosides .
Appearance: Fine, dark green to brownish-green powder with characteristic herbaceous aroma
Flavor: Bitter, slightly astringent, with typical epimedium notes
Solubility: Partially soluble in water; icariin and other flavonoids are more soluble in alcohol or hydroethanolic solutions
Extraction Ratio: Available in various ratios (10:1, 20:1) and as standardized icariin extracts
Our process is optimized to preserve the delicate prenylated flavonoid glycosides:
Sustainable Sourcing & Authentication: Epimedium leaves are sourced from certified cultivation regions. Raw material is authenticated via TLC and HPLC to confirm species and icariin content .
Cleaning & Drying: Leaves are thoroughly cleaned, sorted, and gently shade-dried or low-temperature dried to preserve heat-sensitive flavonoids.
Size Reduction: Dried leaves are milled to a uniform particle size to optimize extraction efficiency.
Hydroethanolic Extraction: Utilizes a precisely calibrated ethanol-water solvent system (typically 50-70% ethanol) to efficiently extract the flavonoid glycosides while preserving their structural integrity .
Filtration & Concentration: The crude extract is filtered to remove insoluble plant material and concentrated under vacuum at low temperatures.
Purification & Standardization: The concentrated extract undergoes purification to enrich icariin content to the desired specification (5%, 10%, 20%, or higher). HPLC analysis guides blending to achieve guaranteed, consistent marker levels .
Spray Drying: The standardized liquid is spray-dried into a fine, free-flowing epimedium extract powder using gentle processing conditions.
Comprehensive Quality Verification: Each batch undergoes rigorous HPLC analysis for icariin and epimedin content, along with testing for heavy metals, microbial safety, and residual solvents.
Epimedium Leaf Extract is utilized for its scientifically-documented, multi-system health benefits:
Supports Male Vitality, Libido & Erectile Function*: Icariin inhibits PDE5, increasing cyclic GMP levels and promoting smooth muscle relaxation in penile tissue, which supports healthy blood flow and erectile function. Clinical studies demonstrate significant improvements in libido, sexual satisfaction, and erectile performance in men with mild to moderate dysfunction .
