Propolis or bee glue is created from resins, balsams and tree saps.

Propolis is also called "bee glue" and can be found in lip balms and toothpaste.

Langstroth discovered that the bees kept filling holes necessary to take the hive out with propolis, bee glue, so he came up with a new solution.

He helped develop antitumor drugs based on propolis, also known as bee glue, a brownish, waxy substance collected by bees from the buds of certain trees and used to caulk beehives.

Other agents of irritant and allergic contact dermatitis may be rosewood, Makassar ebony, cocobolo wood, African blackwood, nickel, reed, propolis (bee glue), chromium and paraphenylenediamine.

Among the therapies on display - most of them outside conventional medicine - were gently rocking beds for relaxation, music that can produce natural opiates in the brain, and bee glue used as antiseptic.

Slides will accompany Dr. Cherbuliez's talk, and he will have samples of beeswax, bee glue (a waxy substance collected from buds of certain trees by bees), royal jelly and bee venom (which is contained in ampules).
