  • Astragalus, a root of plant from legumes family, is useful as up-regulator of immune system. It has been used for thousands of years in China for treatment of chronic hepatitis, as an adjunct to chemotherapy, and to prevent cold and flu, especially when used in combination with herbs like echinacea.
  • Astragalus is useful as an adaptogen in helping the body compensate for excessive stress, viral illness, and cancer. Its antioxidant activity boosts immune system, defends against free radical oxidative damage to cells.


  • It seems a little farfetched that astragalus would be useful for conditions ranging from common cold to three different types of cancer. To our thinking, the more different illnesses a supplement is supposed to help, the less likely it is to be of use for any of them.
  • Because astragalus is thought to stimulate immune function, it may decrease the effectiveness of any treatment that suppresses the immune system, including certain types of chemotherapy.
  • The safety and effectiveness of astragalus are not yet clearly established.

Astragalus may stimulate disease activity and worsen certain autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and lupus. Because astragalus appears to reduce the rate of lithium excretion, some individuals may require a lowering of their lithium dose.

DOSAGE:Precise dosing is not available for astragalus. This is due to the fact that astragalus is used in a variety of forms, including soups, teas, extracts, and pills.

Some experts suggest that it should be used only under the supervision of a qualified Chinese herbalist. If you do elect to try it, remember to include it in your list of medications when you visit your doctor and other health care providers.
