The purple coneflower may work the front line of the immune/defense system of adenoids, tonsils, thymus, lymph nodes, appendix, spleen, and bone marrow to kill bacteria and sweep bacterial debris and dead cells out through the lymphatic fluids. Echinacea may stimulate the immune system by dispatching white blood cells to fight infection, and may be especially good in the digestive tract for removing bacteria causing diarrhea. It has properties of blood purifying and may help accelerate healing if infection already exists. Prairie natives use echinacea’s medicinal purposes for everything from colds to cancer, and was prescribed by American physicians into the 1920’s, later being replaced by antibiotics. In 1993 German physicians prescribed echinacea to more than 2.5 billion cases of infection.
