It is a creamy substance emitted by the subpharyngeal glands of worker bees. The name “royal jelly” stems from the fact that the larvae which are destined to be queens, as well as adult queens eat exclusively this food. Royal jelly contains the critical element that evolves bee from worker to queen.
Royal jelly is a rich source of vitamins, amino acids, enzymes and mineral elements. Many of its components still remain unidentified.
