Echinamide® describes a patented, super-extracted Echinacea purpurea liquid produced and organically grown (in accordance with the California Organic Foods Act of 1990 and certified by the North Okanagan Organic Association (NOOA)) directly by Natural Factors in British Columbia, Canada. Combined from the roots and flowers of Echinacea purpurea, picked at their peak and on-site lab certified to be the highest potency (containing standardized potencies of the three main actives: alkylamides, polysaccharides, cichoric acid). Consumers will recognize this potency by a tingling sensation on the tongue. Echinamide contains these actives in a base of the whole herb, so that none of the minor actives are missing. Natural Factors uses Echinacea purpurea (there are at least 9 species of echinacea) because this species contains the highest levels of alkylamides, cichoric acid and polysaccharides. Not all echinacea products qualify to be called Echinamide. Over several decades, Natural Factors developed this proprietary, double-extraction process which obtains the water-extracted polysaccharides and cichoric acid, as well as the alcohol-extracted alkylamides. Choose Echinamide when you want the best that echinacea has to offer!
