Introduction and description

Royal jelly is a honey bee secretion that is used in the nutrition of larvae, as well as adult queens. It is secreted from the glands in the hypopharynx of worker bees, and fed to all larvae in the colony, regardless of sex or caste.

When worker bees decide to make a new queen, either because the old one is weakening, or died, they choose several small larvae and feed them with copious amounts of royal jelly in specially constructed queen cells. This type of feeding triggers the development of queen morphology, including the fully developed ovaries needed to lay eggs. The photo below shows the larvae surrounded by royal jelly.

According to the research done and published on PubMed, Royal jelly has considerable healing potential. It is anti-viral, anti-bacterial , and boosts the immune system thus helping in wound healing. It has anti-tumour capabilities – see references below. It also appears to have helpful effects in cases of dementia and dAlzheimers. It also helps in collagen production, as such it has so called 'anti-aging' properties. And it also has some very interesting effects in the infertile .  It also appears to have a helpful effect during the menopause.

Background

One of the more intriguing things that came out of the research I did on Royal jelly was to discover there is  a link between BPA and breast cancer.

Bisphenol A (BPA) is a man-made carbon-based synthetic compound used to make certain plastics and epoxy resins; it has been in commercial use since 1957. BPA-based plastic is used to make a variety of common consumer goods (such as baby and water bottles, sports equipment, and CDs and DVDs) and for industrial purposes, like lining water pipes. Epoxy resins containing BPA are used as coatings on the inside of many food and beverage cans. It is also used in making thermal paper such as that used in sales receipts.

The paper that makes this link is the following.

Effect of royal jelly on bisphenol A-induced proliferation of human breast cancer cells. - Bisphenol A (BPA) is an environmental estrogen that stimulates proliferation of human breast cancer MCF-7 cells. Royal jelly inhibited the growth-promoting effect of BPA on MCF-7 cells, in addition, this inhibiting effect of royal jelly was heat-stable

Method

Sometimes you eat it, sometimes it is used as an ointment.

How it works

Very complicated, it is best to refer to the papers below.
