Historically, one of the most valued groups of natural medicines is that of bee pollen, propolis, and royal jelly. Fresh Royal jelly is a unique, thick, milky substance that the worker bees manufacture and feed to the Queen bee. It's the sole source of nutrition of the Queen bee and aids her everyday vitality. The worker bees mix honey and bee pollen with enzymes in the glands of their throats to produce royal jelly.
