What Is Propolis? A Guide For Beginning Beekeepers
Propolis is a sticky substance produced by honey bees using resins collected from trees and plants. To make propolis, bees mix the resins with wax and other material. Bees use propolis, or “bee glue”, to seal cracks and gaps in the hive, as well as to protect the hive from pests and diseases (hence, “bee penicillin”).
