I am having a debate with another bee dork about propolis and its definition. I think that propolis is made by the bees by combining tree resin, pollen, wax and enzymes. The other dork thinks that propolis describes the initial sap or resin of plants and is LATER combined to make a substance also referred to as propolis. Is the term propolis refering to the product made by bees or is it the substance colleted by the bees? (or both?)
