Honey is recommended for breast cancer in moderation











However, Brazilian propolis has also been found to cause acute kidney failure. Propolis has been shown to produce estrogenic effects in human breast cancer cells through activation of estrogen receptors. One 2016 study reported that Turkish propolis in low doses protected ER+/PR+ breast cancer cells by inhibiting cellular apoptosis (programmed cell death). We do not recommend taking propolis as a dietary supplement.

Royal jelly is a bee secretion that is used to feed the larvae in a honey bee colony. It has traditionally been thought to improve menopausal symptoms. Royal jelly has been found to have estrogenic effects in human breast cancer cells, enhancing their proliferation. It should also be avoided by breast cancer patients, survivors and those at high risk.

Cases of honey food poisoning ("honey intoxication" or "mad honey poisoning") have been reported as a result of consuming grayanotoxin-contaminated honey. Grayanotoxin and similar neurotoxins can cause serious heart disturbances, among other symptoms. Grayanotoxin is found in the pollen and nectar (and other parts) of rhododendrons and other plants of the Ericaceae family, including the western azalea, California rosebay, mountain laurel, and sheep laurel. Honey from Japan, Brazil, United States, Nepal, British Columbia, and Turkey on occasion have been found to contain grayanotoxin. Consumers should assure themselves of the quality and safety of any specialty honeys they consume.
