Astragalus root is used in both traditional Chinese and Western herbalism as an immune tonic. Modern research has examined astragalus’ benefit to specific and nonspecific immunity. This herb stimulates the body’s immune action against viruses, has a mild antibiotic action and increases the activity of white blood cells. These properties make it a relevant herb for recurring colds, debilitating viral infections and chronic illnesses such as glandular fever, chronic fatigue syndrome, Ross River and AIDS. Further research shows that it is a safe and useful adjunct to chemotherapy, reducing side effects of the medication.
Astragalus root may also strengthen digestion, raise metabolism, and assist in the healing of wounds. It has been found to be useful for chronically weak lungs and low energy levels.
