Royal Jelly is the milky-white gelatinous substance secreted from the cephalic glands of nurse worker bees (Apis mellifera) for apparently the sole purpose of stimulating the growth and development of the queen bee.
Royal jelly consists of an emulsion of proteins, sugars, lipids and some other substances in a water base. Proteins make up about 13% of royal jelly. One protein in royal jelly possesses antibiotic properties against gram-positive bacteria. About 11% of royal jelly is made up of sugars, such as fructose and glucose. Lipids comprise about 5% of the substance and consist mainly of medium-chain hydroxy fatty acids which are also thought to possess antimicrobial properties.
Royal Jelly has antibiotic, anti-inflammatory and wound-healing effects.
