Propolis is produced by bees to prevent the penetration of foreign bodies, pathogens and germs into the beehive. It consists of essential oils, resin, balsams and beeswax. It has been valued as a “bee antibiotic” since ancient times, and due to its antibacterial, antiviral and fungicidal effects, propolis is an important protective substance – and not just for bees. It supports the immune system and is ideal in the winter.
