Bee propolis, also called bee glue, is made from tree propolis, a sticky resin that seeps from the buds and bark of certain trees. Bees gather propolis and blend it with wax flakes secreted from glands in their abdomens. Bees sterilize their hive by coating it with propolis. Its natural antiseptic qualities ensure a clean environment for healthy brood rearing. Shown to possess antibacterial and antifungal properties, propolis has been used as a natural antibiotic. One component of honeybee propolis, caffeic acid phenethyl ester (CAPE), is known for its anticancer, anti-inflammatory and immune-modulating properties. Although the molecular basis for these properties isn't known, propolis has been used to stimulate immune responses, soothe allergies, and reduce susceptibility to colds and flu. Studies by Polish researchers showed that besides fighting bacteria and fungi, propolis stimulates some enzyme actions, inhibits the growth of protozoa, accelerates bone formation and regenerates tissue.
