Echinacea, a member or te sunflower family, was first used by Native Americans to treat a variety of illnesses and injuries. Knowledge of the herb’s potent properties was passed on the white setlers who rapidly discovered its ability to relieve cold symptoms. By 1920, American doctors prescribed Echinacea more than any other medicinal plant preparation. In the 30’s and 40’s Echinacea fell out of favor in lui of the newly discovered antibiotics.
There are 3 different varieties of Echinacea with E. purprea and E. pallida being the most studied. When Echinacea extracts are combined with wild indigo and white cedar, seemingly greater cold and flu is provided. The bottom line is that there is a plethora of information and research on these supplements and they seem to be safe and somewhat effective.
