I.  What is Echinacea?
        Echinacea is the scientific name for the purple coneflower indigenous to eastern and central United States and southern Canada (http://mothernature.com/articles/echinacea/article2.stm).  Its common name comes from the purplish pink ray-like pedals that surround a center cone.  Echinacea has 2-5 feet long stems covered with dark green leaves.  Drought and poor soil have little influence on this tolerant plant (http://www.egregore.com/herb/echinacea.html).  There are nine different species of Echinacea, though only Echinacea angustifolia, Echinacea pallida, and Echinacea purpurea are popularly used for medical purposes (http://mothernature.com/articles/echinacea/article2.stm).
