Astragalus is classified as a major tonic herb within the Chinese herbal system. These types of herbs are not medicinal in nature, in that they do not correct specific ailments, but are used in a tonifying fashion rather than to cure an already existing illness. They are considered extremely healthy foods and astragalus, as such, offers tremendous value, often compared to ginseng, as a naturally stimulating energizer and immune enhancing adaptogen.
