Astragalus (Astragalus membranaceus), or Huang Qi, is a cornerstone of traditional Chinese medicine and a premier adaptogen. Its root is packed with astragalosides, polysaccharides, and flavonoids that stimulate immune cell activity (T-cells, NK-cells, and macrophages), promote interferon production, protect kidney nephrons, and enhance adrenal gland function to help the body resist physical and mental stressors.
Educational information only — never stop or change a prescribed medication without talking to your prescriber first.
Because it stimulates the immune system, avoid using if you are taking immunosuppressive medications (e.g., after organ transplants) or have active autoimmune diseases (like lupus or rheumatoid arthritis) unless supervised by a specialist. May interact with lithium.
