Astragulus, Astragalus membranaceus, is an adaptogenic and tonic herb used in traditional Chinese medicine to boost energy and strengthen immunity. Research suggests that the polysaccharides and saponins in astragalus may be helpful to those with heart disease, improving heart function and providing relief from symptoms. Astragulus appears to restore immune functions in people whose immune system have been weakened by chemotherapy or chronic illness. It has antibacterial and antiviral properties, making it useful as a topical treatment for healing wounds. It can be helpful in preventing and treating common colds and respiratory infections. Astragulus may also have benefits in treating allergic asthma.
When used appropriately, astragalus appears to be very safe and to have few side effects. Very high doses may suppress the immune system. So you should avoid using astragalus if you are taking immune-suppressing drugs. Pregnant or nursing women should not use astragalus root.
Can be taken as a decoction, tincture, glycerite, syrup, capsule or powder.
