Belonging to the legume family, astragalus is a low shrub reaching only 16 to 36 inches in height, with gray branches. It has been used historically in China to boost immune response, thereby increasing energy, strength and stamina. There are over 2,000 types of astragalus growing around the globe; however, Astragalus membranaceus is the one primarily used for medicinal purposes. Astragalus powder is prepared from dried astragalus root and it may be beneficial for many human ailments. However, it is recommended that you must first consult with your doctor before you consider taking astragalus powder.
Adaptogen
Astragalus is an adaptogen, which means it helps the body adapt to stress. Regular use of astragalus supports adrenal gland functions and encourages healthy production of cortisol -- which is a steroid hormone produced by the adrenal glands in response to stress and fatigue.
Cancer
Astragalus has been found to increase the growth of natural killer T cells in your body that destroy foreign cells such as cancer cells, according to the University of Colorado, Denver. However, most of these findings are based on animal research models, which makes it difficult to say if the results apply to humans as well.
Diabetes
Astragalus may be useful by itself, or in combination with other herbs, for the treatment of diabetes. However, patients taking oral medications for diabetes or using insulin must consume astragalus only under the supervision of a qualified medical practitioner. Astragalus may also increase the effects of diabetic medications, although more study is needed to confirm this.
HIV
In laboratory studies, astragalus has shown to protect against retrovirus infection, commonly known as HIV infection. The antiviral effect of astragalus is largely due to its immunostimulant properties and interferon, a type of antiviral agent, production, the Huntington College of Health Sciences notes. The phyto compounds found in astragalus may block the spread of retrovirus in early stage HIV patients.
