echinaceaCommonly known as purple cornflower, Echinacea is a genus in the daisy family, Asteraceae. Echinacea is an herbal remedy widely employed in fighting colds; however, because of the close relationship between Echinacea and ragweed, and the allergenic cross-reactivity between the two, those who have allergies to ragweed are advised to avoid Echinacea.
