Propolis is natures antiseptic marvel. Eating small doses of propolis daily can help strengthen the immune system against fungi, bacteria, and viruses, including the flu. Some people prefer the raw solid propolis so they can blend it as needed instead of having it premixed into a propolis tincture. Unlike medicine, which attacks both healthful and harmful bacteria, propolis only goes after bad bacteria. Propolis is not affected by the various mutations of bacteria, and it works against all strains in general. Propolis is gathered by bees made from resin that is seeped by tree bark or buds, and mixed with waxy flakes. Contents of propolis include 55% resin and balsam, 30% beeswax, 10% ethereal and aromatic oils, and 5% pollen. Our solid propolis comes in a 0.5 oz. jar.
