A member of the pea family, Astragalus is used medicinally in its native China as an immune strengthener and general tonic. In fact, it is one of the best herbs in the world for enhancing the protective effects of the immune system. Astragalus increases the levels of certain immune cells that fight viruses and other microbial intruders. Astragalus also stimulates the secretion of a powerful anti-viral chemical known as interferon, which prevents viruses from replicating.
