Herbal supplements can help strengthen the immune system and fight infections. Adaptogens, which include eleuthero, Asian ginseng, astragalus, and schisandra, are thought to help keep various body systems-including the immune system-functioning optimally. They have not been systematically evaluated as cold remedies. However, one double-blind trial found that people who were given 100 mg of Asian ginseng extract in combination with a flu vaccine experienced a lower frequency of colds and flu compared with people who received only the flu vaccine.1

Herbs that support a person's immune system in the fight against microbes include the following: American ginseng, andrographis, Asian ginseng, astragalus, coriolus, eleuthero, ligustrum, maitake, picrorhiza, reishi, schisandra, and shiitake.1
One Chinese preliminary trial also found that astragalus could decrease overactive immune function in people with systemic lupus erythematosus.1 However, much more research is needed to know whether astragalus is safe in lupus or any other autoimmune disease.

Astragalus is native to northern China and the elevated regions of the Chinese provinces, Yunnan and Sichuan. The portion of the plant used medicinally is the four- to seven-year-old dried root, collected in the spring. While over 2,000 types of astragalus exist worldwide, the Chinese version has been extensively tested, both chemically and pharmacologically.1
