One of North America’s best-loved medicinal herbs is echinacea (Echinacea purpurea and other species), also known as purple coneflower. Plant compounds in echinacea have been shown to stimulate immune function, helping the body fight infections and cold and flu symptoms. Echinacea products from webber naturals contain certified organic Echinilin®, a clinically studied Echinacea purpurea extract that gets rid of your cold three times faster! Echinilin used in Cold-A-Tak products is standardized to not one, but three active compounds, namely alkylamides, polysaccharides, and cichoric acid.
