Astragalus propinquus
Astragalus and its extracts have been used in traditional Chinese medicine for thousands of years. It is known to support a healthy immune system as well as a healthy cardiovascular system, due to its antioxidant action and high amino acid concentration. Also, it is thought to boost the body's resistance to viral infections by stimulating the production of interferon, the body's own anti-viral agent.
To use: Take one capsule daily with a meal or glass of water, or as directed by your physician.
