What is high quality health benefits echinacea?

There are at least 9 species of high quality health benefits echinacea . Those most commonly studied are E. purpurea, E. pallida, and E. angustifolia.
Echinacea is native to the United States, specifically Kansas, Nebraska, and Missouri. Because of confusion regarding the identification of echinacea species, much of the early research in Europe attributed to E. angustifolia was probably conducted on E. pallida. E. angustifolia and high quality purple coneflower plant are perennial herbs with narrow leaves and stout stems that grow from 90 cm to 1.2 m in height that blossom as a single lavender or purple flower head. When chewed, the plant imparts a pungent taste and causes tingling of the lips and tongue.
