The Propolis (Greek pro 'before' and polis 'city') The name comes from the fact that the bees use the propolis as well as of at the entrance of their hives to avoid any draught. The propolis is a resinous mass made by the bees with antibiotic, antiviral and antifungal properties.

In the hive, the temperature is around 35 degrees Celsius with high humidity. Both are ideal conditions for diseases. With the help of the propolis the bees are able to seal the cracks and crevices. In addition, it helps bacteria to inhibit or even to kill any bacteria, fungi and microorganisms in their development. The cells for the brood comb are also covered with a wafer-thin layer of propolis.

Propolis is collected in autumn. The harvest depends on the supply of resin and can vary from 50 - 500 grams per bee colony. The substance of propolis consists of about 55% natural resin, around 30% wax, approximately 5% pollen and 10% of essential oils from flower buds and saliva.
