Product Description
Rhizoma Drynariae Extract is a premium natural herbal concentrated extract derived from the dried rhizome of Drynaria fortunei (Kunze) J. Sm., a classic edible and medicinal herbal plant with a long history of application. Centered on core active ingredients including naringin and total flavonoids, Rhizoma Drynariae Extract possesses outstanding bone nourishing, joint protecting, anti-inflammatory and antioxidant properties. It is a core functional raw material widely used in bone health supplements, joint care functional foods and daily sub-health conditioning products. We provide two mainstream concentration specifications: 10:1 standard grade and 20:1 high-concentration grade, produced through standardized low-temperature extraction and multi-stage purification technology to fully retain natural active ingredients.
Different from ordinary raw Drynaria Fortunei rhizome powder with high impurity content and low active concentration, our standardized Rhizoma Drynariae Extract undergoes multi-stage concentration, purification and spray drying treatment. The production process effectively removes redundant crude fiber, starch and inactive impurities, greatly enriches the content of naringin and flavonoid active substances, and solves the problems of weak efficacy, poor absorption and unstable quality of ordinary raw herbal powder. All production procedures comply with GMP purification standards, with strict heavy metal and microbial detection, ensuring safe, clean and stable quality for food and health product applications.
As a classic natural bone health raw material, Rhizoma Drynariae Extract exerts excellent bone nourishing and strengthening effects. The rich naringin and flavonoid components can promote bone cell metabolism, accelerate bone tissue repair, enhance bone density and bone toughness, and effectively relieve bone discomfort caused by aging, exercise wear and sub-health state. It provides effective daily conditioning for middle-aged and elderly people, sports enthusiasts and people with weak bone health.
In terms of joint protection and anti-inflammation, Rhizoma Drynariae Extract can inhibit the production of inflammatory factors, relieve joint inflammatory swelling and soreness, reduce joint tissue wear, maintain joint flexibility and normal physiological functions, and effectively improve joint sub-health problems caused by long-term strain and aging.
In addition, the natural flavonoids and polyphenols contained in Rhizoma Drynariae Extract have good antioxidant activity, which can scavenge excess free radicals in the body, reduce oxidative damage to cells and tissues, delay body aging, and enhance human immune regulation ability. With mild herbal properties, pure natural source and no side effects, it is suitable for long-term daily health conditioning.
Our finished Rhizoma Drynariae Extract is uniform yellowish brown fine powder with delicate texture and inherent natural herbal fragrance, no caking and no peculiar smell. Every batch of products passes full-index quality inspection to ensure stable active ingredient content and consistent batch quality. It has good water solubility and formula compatibility, which can be perfectly applied in health care capsules, tablets, solid beverages and compound functional food formulas.
