Royal jelly (SEDA-21,494) is a viscous secretion produced by the pharyngeal glands of the worker bee. Apis mellifera. It is widely used in alternative medicine as a health tonic. Its internal use by atopic individuals can cause severe, sometimes even fatal, asthma and anaphylaxis (9-11). Topical application can lead to contact dermatitis (12). 

In most animal parasitic nematodes, pharyngeal glands secrete digestive enzymes onto ingested food particles as they enter the pharynx. In A. suum, an esterase, amylase, maltase, protease, peptidase and lipase are secreted into the pharynx during feeding. The pharynx of species that feed on host mucosal cells may also contain hyaluronidase and additional enzymes specialized for digestion of host tissues (141).

Royal jelly is a milky white, viscous substance secreted by the pharyngeal glands of the worker bee (honeybee). Apis mellifera L., an insect of the family Apidae. It is the food for all bee larvae for the first three days of life but is reserved as food for queen bees for the rest...
