About

Echinacea is one of the most studied herbal immune supplements. Its alkylamide and polysaccharide constituents activate macrophages, enhance phagocytosis, and stimulate natural killer cell activity. Cochrane-reviewed meta-analyses suggest modest reduction in cold duration and severity when started at symptom onset.

How It Works

Activates macrophages, enhances phagocytosis, and stimulates NK cell activity through alkylamide and polysaccharide constituents; modulates cytokine production (TNF-alpha, IL-1, IL-6).
