May provide relief of symptoms of common cold and flu. Our Echinacea is produced using extracts of freshly harvested, organically grown Echinacea purpurea herb and root, picked fresh and used within 24 hours of harvest. The benefit of using freshly harvested herbs has been demonstrated to contain more active substances compared with those obtained from equivalent amounts of dried herb. This is why, when you need a herbal remedy to help you fight the misery of colds and flu, not all Echinaceas are the same.
