Widely known as purple coneflower, Echinacea was highly revered by the Native American of the Great Plains. Nature's Plus Herbal Actives Echinacea root and rhizome extract is uniformly standardized to a minimum of 4% (8 mg) echinacosides to guarantee that each and every capsule provides consistent potency and activity. Each capsule, providing the greatest concentration of active botanical principles, maximizes the synergistic benefits of the whole root, which naturally contains glycosides, polysaccharides (echinacinB and inulin) and isobutylamides (echinacein). |
