Echinacea purpurea extract is obtained from the aerial parts and/or roots of Echinacea purpurea (purple coneflower) through aqueous-ethanol extraction. The extract contains a complex of immunoactive compounds including cichoric acid, alkamides (isobutylamides), polysaccharides, and glycoproteins. These constituents work synergistically to modulate innate and adaptive immune responses.
Clinical trials support its efficacy in reducing the duration and severity of common cold symptoms. Commercially, E. Purpurea extract is one of the top-selling herbal ingredients in dietary supplements, immune support products, and traditional herbal remedies.
