Royal jelly is used for asthma, hay fever, liver disease, pancreatitis, sleep troubles, premenstrual syndrome (PMS), stomach ulcers, kidney disease, bone fractures, menopausal symptoms, skin disorders, and high cholesterol. It is also used as a general health tonic, for fighting the effects of aging, and for boosting the immune system. Royal jelly is produced by bees and is the substance the bees produce when it’s time to “make” a new queen bee. The bee colony has one queen who lays all the eggs for the colony. When she runs out of steam, worker bees feed a new bee royal jelly, which will turn this bee into a queen, capable of reproducing after mating. That aura of “magic” has enhanced royal jelly’s reputation.
