The bees carry the propolis back to their hives and mix it with their salivary secretions and wax flakes. Propolis contains 55% resins and balsams, 30% beeswax, 10% etheric oils, and 5% pollen.
Beeswax like all the other hive products can cause allergic reaction especially in people who have an allergy history. Beeswax allergy is a sensitive reaction towards the bee glue or the propolis extant in its composition. This allergy should be identified properly in order to be treated efficiently. It is very difficult to decide if a person is allergic to pollen or other elements that form the beeswax. The research done in the domain has shown that pure beeswax does not trigger an allergic reaction. The beeswax allergy is actually caused by the propolis in beeswax. Some people may be allergic only to the pollen produced by certain plants.
