Echinacea Leaf Herb

Echinacea has been divided into nine different species, all of which are indigenous to North America. Native Americans from the Great Plains region used them as traditional medicines. 
Based on the theory that it might boost the immune system to more successfully fight infection, echinacea is marketed as a dietary supplement for the common cold and other infections. For the treatment of wounds and skin issues, topical echinacea products have been recommended. 
Several echinacea species, most frequently Echinacea angustifolia or Echinacea purpurea, can be found in dietary supplements.
