Astragalus (Astragalus membranaceus) is a type of flowering plant. The root has been used for centuries in traditional Chinese Medicine (TCM).
Astragalus is considered an adaptogen. Adaptogens are a class of natural substances that are believed to stimulate the body's resistance to physical, environmental, and emotional stressors. The chemicals in astragalus also seem to stimulate the immune system and reduce swelling.
People commonly use astragalus for hay fever, diabetes, kidney disease, and many other conditions, but there is no good scientific evidence to support these uses. There is also no good evidence to support using astragalus for COVID-19.
There are many species of astragalus. Some species contain a nerve toxin and have been linked to livestock poisonings. These include Astragalus lentiginosus, Astragalus mollissimus, and others. But these species usually aren't found in dietary supplements. Most astragalus supplements contain Astragalus membranaceus. Also, don't confuse astragalus with tragacanth. These are different plants.
