1 oz. (28 grams) Echinacea ang. Root c/s (Echinacea angustifolia) Echinacea is herbal medicine's first choice of treatment for colds. Stimulating the immune system, the herbs can also be used to treat chronic yeast infections in women and to prevent urinary tract infections in both sexes. The roots and the whole plant are considered particularly beneficial in the treatment of sores, wounds, burns, boils, etc, possessing cortisone-like and antibacterial activity. The plant was used by North American Indians as a universal application to treat the bites and stings of all types of insects. Echinacea angustifolia was widely used by the North American Plains Indians for its general medicinal qualities. Echinacea was one of the basic antimicrobial herbs of eclectic medicine from the mid 19th century through the early 20th century, and its use was documented for snakebite, anthrax, and for relief of pain. In the 1930s echinacea became popular in both Europe and America as a herbal medicine. According to Wallace Sampson, MD, its modern day use as a treatment for the common cold began when a Swiss herbal supplement maker was "erroneously told" that echinacea was used for cold prevention by Native American tribes who lived in the area of South Dakota.
