What is royal jelly?
In the bee colony there are male drones and female bees. Whether a female larva develops to a worker or a queen, is decided by the worker bees. Worker bees are fed with regular food, while a special nutritional sap induces that a young female bee evolves to a queen. If a larva is fed with royal jelly after three days of hatching, she turns into a queen bee. This special nutrition is called "royal jelly". When consumed by healthy people, royal jelly increases their resistance to mental and physical fatigue.
