Nature's Answer Echinacea & Goldenseal 900mg Vegan Capsules For Immunity gives you time-tested immune support. Our immune system is what keeps us healthy and is especially important during all the seasons. Guaranteed to contain a specific quantity of a known marker compound, and laboratory tested utilizing Advanced Botanical Fingerprint Technology to ensure consistent potency. Each serving contains 900 mg proprietary herbal blend of Echinacea (Echinacea purpurea aerial parts, Echinacea angustifolia whole herbs) and Goldenseal (Hydrastis canadensis) root. During a cold, flu or infection, especially of the mucous membranes, echinacea can go to work to activate immune fighters, such as macrophages. These important defenders work to engulf and rid the body of virus-infected cells, bacteria, toxic wastes-helping to clear the debris of an "immune battle" from the site. Echinacea can also help strengthen a protective gel that surrounds many of the body's cells, thus keeping invading organisms from gaining a foothold. Golden seal, meanwhile, can help control the inflammatory process if it gets too carried away-if there is too much heat, redness, or swelling. The immune system can actually be inhibited in its protective job when this happens. It can also help bring more blood into the micro-circulation in the areas that are infected, such as the sinus cavities or urinary tract. It can help the body go through the infection much faster by bringing in more of the macrophages (that echinacea is activating) and helping to remove debris from the site.
