Astragalus is a complex combination of polysaccharides, triterpene glycosides, flavonoids, amino acids, and trace minerals. Astragalus may restore T-cell (a specific type of white blood cell) counts to relatively normal ranges in suppressed patients. Astragalus polysaccharides have also been shown to stimulate pituitary-adrenal-cortical activity and restore depleted red blood-cell formation in bone marrow. Again confirming traditional Chinese medicine, astragalus has been shown to stimulate the body�s natural production of interferon and is also useful for the treatment of Alzheimer�s disease, common cold/sore throat, chemotherapy support, and immune function.
