* High cholesterol. There is some evidence that royal jelly might lower cholesterol levels in people with high cholesterol.
* Premenstrual syndrome (PMS). Some evidence suggests that a specific combination product (Femal, Natumin Pharma) seems to decrease certain symptoms of PMS including irritability, weight increases, and edema when given over a period of 2 menstrual cycles. Each tablet of this product contains 6 mg of royal jelly, 36 mg of bee pollen extract, and 120 mg of bee pollen plus pistil extract. It is given as 2 tablets twice daily.
* Cancer : According to a study published in a 2009 edition of the BMC Complementary and Alternative Medicine, royal jelly fights cancer by suppressing the blood supply to tumors. When the Japanese researchers tested various royal jelly types on umbilical vein tissue cultures, all of them inhibited the formation of blood vessels, especially those richest in caffeic acid, a compound responsible for the greatest suppressive levels. Moreover, since the fatty components of royal jelly contain estrogenic effects - as proved by a study published in the December 2010 edition of PLoS One - it is possible that royal jelly can treat breast and cervical cancer.
*Asthma.
*Hay fever.
