Polygonum multiflorum powder, also known as Polygonum multiflorum root extract, He Shou Wu or Shou Wu root powder, is derived from the precious Polygonum multiflorum root, a traditional herb that has been revered for centuries. The extract is rich in bioactive ingredients, including stilbene glycosides (2,3,5,4'-tetrahydroxystilbene-2-O-glucoside), anthraquinones (rheic acid, chrysophanol, rhein), lecithin, and polysaccharides, making it highly sought after in cosmetics and nutraceuticals.
Global demand is growing for anti-aging, liver support, and cognitive health formulations. It serves as a natural alternative in hair care to promote melanin production and reduce gray hair. We specialize in high purity, full spectrum extracts with custom standardization to tailor the ratio and bioactive properties to your formulation needs.
Standardized to >5% stilbene glycosides to ensure antioxidant benefits. HPLC-verified purity with heavy metals below 0.1ppm.
Retains >90% anthraquinones and polysaccharides. Micronized powder (<80 mesh) allows for easy incorporation into capsules and liquids.
Sourcing directly from certified farms where soil alkalinity results in higher active content than regular Fo-ti.
Custom water-soluble or fat-soluble extracts. Available in pre-formulated blends like Polygonum + Black Sesame.
