Bees use propolis, among others: to create barriers placed at the entrance to the hive. These barriers function like disinfection gates, i.e. they cleanse the bees passing through them from bacteria and other unwanted substances. Propolis may contain up to several hundred different antibacterial substances and is considered the most biologically active bee product. It also contains flavonoids, vitamins and minerals.Bee products in dietary supplementsPropolis and other bee products are increasingly used as a supplement to the daily human diet.
