Echinacea is a most famous "immune herb" in western countries, and continues to be the best selling herb for many years. For the last five years, our research group has cooperated with Institute of Medicinal Plants in Huairou District of Beijing, carrying out studies on Echinacea purpurea, which involved botany, cultivation, pharmacognosy, phytochemistry, quality control, pharmacology and toxicology of the species. Two other species introduced from Canada, Echinacea angustifolia and Echinacea pallida, were also included in the taxonomic, cultivated and pharmacognostic studies. The results acquired have opened up the path to introduce Echinacea species into Traditional Chinese Medicine, thus established the possibility of developing more promising drugs from them.
