Bee propolis, one of Mother Nature's most adaptable materials, has been used for thousands of years for its inherent anti-bacterial, anti-fungal, and anti-viral capabilities. With just a few drops per day, you can strengthen your immune system. If you are pregnant, nursing, allergic to bee products, poplar tree products, or balsam of Peru, see your healthcare provider before using. Avoid children at all costs. Keep out of direct sunlight when storing.
