Astragalus
Astragalus is an herbal supplement that has been used for centuries in traditional Chinese medicine. Though there are over 3,000 species of astragalus, only two are primarily used in supplements — Astragalus membranaceus and Astragalus mongholicus.
It’s purported to enhance the immune system and reduce inflammation. It’s also used to help treat heart conditions, kidney disease and chronic fatigue.
