Royal jelly is a creamy substance produced by bees as food for the future queen. It is secreted from specialized glands in the pharynx of worker bees and differs from honey in this regard, as honey is not secreted from the bees' bodies. The royal jelly nourishes the bee larvae, which will eventually become queens. Initially, these larvae do not differ from those that become workers, but under the influence of royal jelly, they grow into queens.
