Astragalus extract is a concentrate of active components obtained from the dried root of the traditional Chinese medicinal herb Astragalus membranaceus (Huang Qi) through ethanol extraction.
Astragalus extract is rich in various bioactive substances, most notably Astragalus polysaccharides and astragalosides (e.g., Astragaloside IV). Additionally, it contains flavonoids, amino acids, and multiple trace elements.
The core efficacy of Astragalus extract is closely linked to its immunomodulatory, antioxidant, and anti-fatigue properties. Research indicates that Astragalus polysaccharides can significantly enhance the body's immune function and promote the activity of immune cells, while astragalosides exhibit strong antioxidant effects, helping to scavenge free radicals and protect cells from oxidative damage.
Furthermore, it has been shown to improve cardiac function, protect the liver, and possess auxiliary potential in antiviral and antitumor applications. In traditional Chinese medicine theory, it corresponds to the effects of "tonifying Qi to strengthen the exterior and promoting diuresis to reduce swelling." Modern research provides scientific substantiation for these claims, highlighting its value in supporting overall resistance and vitality.
In the pharmaceutical and health product sectors, it is widely used to enhance immunity, combat fatigue, assist in the treatment of cardiovascular diseases, and provide supportive care during cancer radiotherapy and chemotherapy.
In functional foods and beverages, it is often added as an ingredient to offer immune support. The cosmetics industry leverages its antioxidant and skin-repairing properties, incorporating it into anti-aging, soothing, and skin-barrier-enhancing products.
Additionally, in the animal health field, it serves as a feed additive to improve the immunity of livestock. Its applications span across prevention, treatment, rehabilitation, and daily wellness, demonstrating significant market potential.
