Echinacea Purpurea

History

This member of the Compositae (daisy) family, sometimes referred to as Purple Coneflower, was popularized by European research commencing in 1939 conducted primarily on the fresh pressed aerial portions of the flowering plant. Echinacea purpurea is scarce in the wild but is considered native to Arkansas and Missouri and traveled eastward after 1968. It is drought and disease tolerant and therefore very easy to cultivate. All Echinacea purpurea currently used in commercial preparations is cultivated.

Function

While the exact mechanism of action is not fully understood, many studies have demonstrated a beneficial effect on the immune system and a normalization of immune cells from use of Echinacea purpurea.
