Echinacea (Echinacea angustifolia, Echinacea pallida, Echinacea purpurea) also known as ‘cone flower’ or ‘snake root’, has a long history of medicinal use in North America particularly for upper respiratory and skin infections. In the 1880s echinacea products were touted as cure-alls by unscrupulous merchants leading them to become known as ‘snake oil’, yet echinacea products are now among the best‐selling herbal preparations. Laboratory studies have confirmed echinacea’s ability to increase natural-killer cells numbers, phagocytic activity and cytokine production and lobe with antiviral, antifungal, anti-inflammatory activity, and clinical trials attest to its effectiveness in preventing and treating upper respiratory tract infections.
