Propolis has an antibacterial, antiviral and antifungal effect, promotes tissue regeneration and has a healing effect. It is a resinous substance that is collected by bees from the buds and bark of plants and further processed with the addition of wax, pollen and enzymes produced by the bees themselves. The bees use it to coat the inside walls of the hive in the areas used for laying eggs and rearing larvae to create a disinfected and protected environment.
