Astragalus (Huang Qi; Astragalus membranaceus), has been used in traditional medicine historically for it’s immunomodulating, antiviral, diuretic properties. Astragalus is enriched with a complex combination of polysaccharides, triterpene glycosides, flavonoids, amino acids, and trace minerals. Astragalus has been studied for its benefits in restoring T-cell (a specific type of white blood cell) counts to relatively normal ranges and inducing pituitary-adrenal-cortical activity to restore depleted red blood-cell formation in bone marrow. Traditional Chinese medicine evidence suggests the adaptogenic ability of astragalus in enhancing immune function.
