Achyranthes Bidentata / Niu Xi

【Benefits】

In traditional Chinese medicine, Achyranthes bidentata (Huai Niu Xi, Chinese Yam Rhizome) is renowned for its effects of tonifying liver and kidney, strengthening tendons and bones, promoting blood circulation to unblock meridians, guiding blood downward, and inducing diuresis to treat stranguria. It effectively alleviates symptoms like liver-kidney deficiency-induced lumbago and knee weakness, meridian obstruction-caused limb numbness, irregular menstruation, dysmenorrhea, and blood stasis-induced swelling and pain. From a modern research perspective, it contains bioactive components such as Achyranthes bidentata polysaccharides, oleanolic acid, and triterpenoid saponins, which have anti-inflammatory, immunomodulatory, blood circulation-improving, and anti-aging effects, helping to enhance physical vitality and regulate vascular health.

【Medicinal Components & Effects】

Achyranthes bidentata is rich in active components. Achyranthes bidentata polysaccharides are the key, exerting immunomodulatory and anti-inflammatory effects by activating immune cells and inhibiting inflammatory mediators. Oleanolic acid has liver-protective and antioxidant properties, protecting cells from oxidative damage. Triterpenoid saponins contribute to strengthening tendons and bones, improving blood circulation, and relieving swelling and pain. These components work together to tonify liver and kidney, promote blood circulation, and maintain the body's motor and vascular health.

【Storage Methods】

• Store in a cool, dry, and well-ventilated place (temperature 10–15℃, humidity below 60%), away from direct sunlight and high humidity to prevent mold, insect infestation, and deterioration.
• Use airtight containers like glass jars or vacuum-sealed bags. After opening, seal promptly to avoid moisture absorption and oxidation of active components.
• Avoid storing with odorous substances to prevent flavor tainting. Regularly check for mold, discoloration, or unusual odor—discard immediately if any spoilage is found.
