Propolis is made by the bees from tree resins, beeswax and many other components. The bees use it as glue around the hive to seal up gaps as well as a powerful antiseptic.
 
We collect the proplis by scraping it off various surfaces inside the hive. While we try to only collect propolis, the ocassional other aticle may also be included such as beeswax and a bee or two.
