    Various Astragalus species are used in alternative medicine around the world.[1][2] This page refers to Astragalus membranaceus, a popular herb used in Traditional Chinese Medicine, also known as Astragali radix or huangqi.[3][4] Astragalus membranaceus can be used alone, but it is also paired with another herb called Angelicae sinensis in Danggui Buxue Tang, a Chinese medicine.[5] Astragalus membranaceus contains several bioactive compounds, including polysaccharides, flavonoids, and saponins. Its major bioactive molecules include calycosin, formononetin, cycloastragenol, and astragaloside IV,[6][7] and another of its bioactive molecules has been patented under the name TA-65 (telomerase activator 65).[8]
