"Royal jelly is a milky secretion produced by worker honey bees. It typically contains about 60% to 70% water, 12% to 15% proteins, 10% to 16% sugar, 3% to 6% fats, and 2% to 3% vitamins, salts, and amino acids. Its composition varies depending on geography and climate. This product gets its name from the fact that bees use it for the development and nurturing of queen bees. Some people use royal jelly as medicine. Don’t confuse royal jelly with bee pollen or bee venom.
Royal jelly is used for asthma, hay fever, liver disease, pancreatitis, sleep troubles (insomnia), premenstrual syndrome (PMS), stomach ulcers, kidney disease, bonefractures, menopausal symptoms, skin disorders, and high cholesterol. It is also used as a general health tonic, for fighting the effects of aging, and for boosting the immune system.
Royal jelly is POSSIBLY SAFE for most people when taken by mouth appropriately. A specific product containing a combination of royal jelly, bee pollen extract, and bee pollen plus pistol extract (Femal by Natumin Pharma) has been used safely for up to 2 months. Another combination product containing royal jelly and flower pollen (Melbrosia) has been used safely for up to 3 months. Royal jelly might cause serious allergic reactions including asthma, swelling of the throat, and death. Rarely, it might cause the colon to bleed, accompanied by stomach pain and bloody diarrhea.
Royal jelly is also POSSIBLY SAFE when applied to the skin appropriately. However, it has caused inflammation and allergic rash when applied to the scalp.
