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”).
Honey bees produce more than just honey – they also make nectar, propolis, beeswax, bee brood, bee venom, royal jelly, and pollen, which all have unique uses for humans. Beekeepers harvest the hive products for a variety of uses including in food and drinks, natural remedies, cosmetics, and dietary supplements.
Honeycomb is the six-sided wax cells built by bees to store pollen, nectar and honey. It’s also used to raise brood. Learn about its construction and uses.
