Echinacea is an herb. Several species of the echinacea plant are used to make medicine from its leaves, flower, and root. Echinacea is widely used to fight infections, especially the common cold and other upper respiratory infections.
Echinacea may increase the effects of caffeine, raising the risk of side effects like nervousness, headache and a racing heart. Because it may boost the immune system, echinacea may reduce the effectiveness of medications designed to suppress the immune system, like prednisone and corticosteroids.
