Propolis: benefits, harvest and extraction
Propolis is a sticky mixture of resins that bees collect from plants, particularly leaf and flower buds, and beeswax. Bees use it to line the inside of their nests, to close cracks and reduce hive entrances, and to line or repair brood combs. Intruding animals that get killed by bees but are too large to be taken outside may be “mummified” with propolis. It’s also used in a mix with wax to seal brood cells. All these applications take advantage of the antibacterial and antifungal effects of propolis and help the hive against diseases.
