Astragalus is a plant native to China and used traditionally in Chinese medicine. The dried root is used to strengthen the body against disease, according to the University of Maryland Medical Center (UMMC). More research is needed to verify the effectiveness of astragalus, as noted by the University of Michigan Health System (UMHS).
Protective Properties
Because astragalus root has antibacterial and anti-inflammatory properties, some people use it as a topical treatment for wounds, according to the UMMC. Astragalus also has antiviral properties, so it may help prevent colds and other upper respiratory infections.
Immune System Function
Astragalus root also may prevent upper respiratory infections by stimulating the immune system. Studies noted by the UMMC have found that astragalus supplements accelerate recovery time and extend life expectancy in individuals whose immune systems have been affected by chemotherapy or radiation. Astragalus also is an alternative method of relieving fatigue and lack of appetite associated with chemotherapy. Additionally, a study cited by the UMHS found that astragalus reduces overactive immune function in people with the autoimmune disorder systemic lupus erythematosus.
Heart and Liver Benefits
Chinese research indicates that astragalus may relieve symptoms and improve heart function in people with severe types of heart disease, according to the UMMC. Further research from China shows possible benefits for patients with chronic viral hepatitis.
