When worker bees decide to make a new queen, because the old one is the jelly effect pdf weakening or dead, they choose several small larvae and feed them with copious amounts of royal jelly in specially constructed queen cells. In the United States, the Food and Drug Administration has taken legal action against companies that have used unfounded claims of health benefits to market royal jelly products.
After three days, the drone and worker larvae are no longer fed with royal jelly, but queen larvae continue to be fed this special substance throughout their development. It is harvested by humans by stimulating colonies with movable frame hives to produce queen bees. Therefore, only in queen cells is the harvest of royal jelly practical. 6 months can produce approximately 500 g of royal jelly.
MRJP1 is the most abundant, and largest in size. MRJPs are shown to be the main medicinal components. In spite of their identical clonal nature at the DNA level, they are strongly differentiated across a wide range of characteristics including anatomical and physiological differences, longevity of the queen, and reproductive capacity. Queens constitute the female sexual caste and have large active ovaries, whereas female workers have only rudimentary, inactive ovaries and are functionally sterile. DNA methylation levels emerged as queens with fully developed ovaries. The incidence of allergic side effects in people who consume royal jelly is unknown. The risk of having an allergy to royal jelly is higher in people who have other allergies.
