History
Echinacea became prominent in American medicine in the late 19th century. H.C.F. Meyer, a German healer, marketed Echinacea as a 'miracle cure,' which he labeled Meyers' Blood Purifier, and used to treat a wide variety of ailments, including diptheria, typhus, and other infections. The so-called 'cure all' drew the attention of American Dispensatory author John King, and Echinacea was introduced into eclectic medicinal practices in 1887. By the 1930s, use of Echinacea spread to Europe, and was sold to American doctors more commonly than any other herb. From 1950-1991, more than 200 studies were published on the chemical, pharmacological, and clinical uses and effects of Echinacea. Echinacea continues to be a popular herbal remedy in the United States, and around the world.
The name Echinacea comes from the Greek word echinos, which means hedgehog or sea urchin, referring to the prickly scales of the dried seed head on the plant.
Physiology Echinacea is rich in polysaccharides and phytosterols, which are believed to simulate the actions of the alternative complement pathway, which causes immune cells to search out bacteria. The roots of E. angustifolia contain glycoside echinacoside, which has a mild antibiotic properties. Other components in Echinacea, such as the polysaccharide echinacin, also have antibiotic and antifungal activity. E. purpurea contains components, mainly echinacin, with cortisone-like activity and which help with wound healing by inhibiting inflammatory hyaluronidase enzyme. E. purpurea also contains the sesquiterpene esters which have immunostimulatory activity.
