Echinacea, also known as Purple Coneflower, has been used for centuries by Native American tribes as an herbal remedy. There are three common species; echinacea purpurea, e. angustifolia, and e. pallida. Echinacea supports the immune system through a variety of mechanisms that aid phagocytosis and T-cell production. Echinacea extracts are standardized to specific levels of marker compounds known to have immune enhancing effects. Caffeic acid derivatives (echinacosides), polysaccharides, polyacetylenes, alkylamides, and flavonoids are among the plant constituents with known activity. NOW® carries Echinacea in several different forms, including a 125mg Angustifolia product standardized to contain 4% echinacosides, our high-potency 400mg Purpurea root product, and several different liquid herbal extracts.
