Natural Radix Isatidis Extract Powder (also known as Radix Isatidis Extract or Radix Isatidis Extract) is a potent herbal supplement derived from the root of Radix Isatis or Isatis tinctoria. Radix Isatis is a traditional Chinese medicinal plant with the main active ingredients being indirubin and indigo alkaloids, polysaccharides (IRPS), organic acids (salicylic acid, etc.), flavonoids and tannins. It has antiviral, anti-inflammatory and immune-boosting properties and is a popular ingredient in health foods and functional foods. The global Radix Isatidis Extract market is expected to grow at a CAGR of 11.4% to reach USD 1.2 billion by 2030, driven by the growing demand for natural antiviral and immune-supporting ingredients in pharmaceuticals and personal care products. Focus is placed on high-purity, standardized extracts with higher bioavailability to ensure sustained effects.
Offering custom formulations (powder/liquid/capsules) with organic or conventional ingredients to meet diverse industry needs.
Proprietary low-temperature extraction technology effectively retains heat-sensitive active ingredients (such as polysaccharides) to maximize their effectiveness.
Stringent testing for pesticide residues, heavy metals and microbial contaminants in compliance with EU/US/China standards.
A direct supply chain from farm to lab ensures cost-effectiveness without compromising purity (available from 25 kg drums to small batches).
Low-temperature ethanol-water extraction process, using a standardized concentration of 10:1, retains more than 90% of heat-sensitive polysaccharides. The content of indirubin (key antiviral compound) is ≥ 5%, verified by high-performance liquid chromatography (HPLC) to ensure the best immunomodulatory effect.
Proven usage ratios: 2-5% in capsules to enhance immunity, 1-3% in serums to enhance anti-inflammatory skin care.
