Echinacea delivers protective qualities essential to achieving great health, naturally. It strengthens your natural immune system defenses by fortifying your most critical cells with natural fighting power. Esberitox combines two types of Echinacea with two additional immune-enhancing herbs, baptisia and thuja. This gives Esberitox a broader spectrum of activity than Echinacea alone. The powerful combination promotes the body's resistive functions by stimulating the production and activity of critical immune cells.
