Echinacea (Echinacea purpurea) is an immune-stimulating herb that is well-documented in both traditional medicine and within the scientific community. The patented extract ECHINAMIDE has been proven consistently to enhance immune system function. When taken at the first sign of infection, ECHINAMIDE may stop a cold from developing, may ease symptoms and accelerate healing. ECHINAMIDE uses a patented extraction method to guarantee the bioavailability of the three known plant actives in Echinacea purpurea: alkylamides, cichoric acid, and polysaccharides. Goldenseal (Hydrastis canadensis) is an antimicrobial and immune-boosting herb. The main active constituent of goldenseal, berberine, is clinically shown to have antimicrobial effects against a wide variety of pathogens, including bacteria, yeast, and fungus. Combining ECHINAMIDE with goldenseal in a fresh herb tincture maximizes the cold-fighting power of the herbal remedy. Natural Factors ECHINAMIDE Anti-Cold Echinacea & Goldenseal Tincture contains certified organic echinacea, which is grown in BC’s Okanagan Valley. The plants are harvested when the active ingredients are at their peak concentration.
