The Latest Weapon in the War on Cancer: Honey Bees
By Dr. Mercola

Propolis, the "caulk" honeybees use to patch holes in their hives, has been used as a natural remedy since ancient times, treating ills ranging from sore throats and burns to allergies.
New research has revealed another exciting use for this seemingly miraculous substance, this time in the fight against cancer.

Propolis Slows Tumor Growth

Propolis has a number of well-known therapeutic properties, including potent antioxidant and anti-microbial action, and healing, analgesic, anesthetic, and anti-inflammatory properties. In the hive, bees use it as a disinfectant against bacteria and viruses, helping to seal cracks and "embalm" invaders that are too large to carry out.
It's been used for thousands of years in folk medicine, but despite its plethora of active components, research on this compound, and therefore its modern medical uses, is limited.

Researchers from the University of Chicago Medical Center, intrigued by propolis' anti-cancer potential, decided to look at one of its bioactive components, caffeic acid phenethyl ester (CAPE), and its impact on human prostate cancer cells.
In cells grown in a lab, even small doses of CAPE slowed the growth of tumor cells. And when low oral doses were given to mice with prostate tumors, tumor growth slowed by 50 percent! What's more, feeding CAPE to mice daily caused the tumors to stop growing, although they returned when the CAPE was removed from their diets.

This suggests the propolis compound works by impacting signaling networks that control cancerous cell growth, rather than by killing the cells directly. However, there are at least four studies on propolis’ apoptotic properties, indicating that technically it is capable of directly killing cancer cells, including prostate cancer, melanoma and more, as well.1
This is not the first time propolis has shown promise in treating cancer. In 2009, propolis was found to suppress the growth of neurofibromatosis-associated tumors (tumors on nerve tissue) by blocking PAK1 signaling. Researchers noted:2
"Since more than 70% of human cancers such as breast and prostate cancers require the kinase PAK1 for their growth, it is quite possible that GPE [green propolis extract] could be potentially useful for the treatment of these cancers, as is Bio 30 [a CAPE-based propolis extract]."

Propolis Has Powerful Immune-Modulating, Anti-Inflammatory Properties

What makes natural compounds so exciting, and often so powerful, is that they don’t simply exhibit one therapeutic action the way, say, most drugs work. Instead, they contain numerous bioactive components that may exert dozens of beneficial actions within your body. This appears to be the case with propolis, which has been found to play a role in over 80 conditions.

Writing in Clinical Reviews in Allergy and Immunology, researchers expanded on some of propolis’ potential effects:4

“Propolis, a waxy substance produced by the honeybee, has been adopted as a form of folk medicine since ancient times. It has a wide spectrum of alleged applications including potential anti-infection and anticancer effects. Many of the therapeutic effects can be attributed to its immunomodulatory functions. The composition of propolis can vary according to the geographic locations from where the bees obtained the ingredients.

Two main immunopotent chemicals have been identified as caffeic acid phenethyl ester (CAPE) and artepillin C. Propolis, CAPE, and artepillin C have been shown to exert summative immunosuppressive function on T lymphocyte subsets but paradoxically activate macrophage function.

On the other hand, they also have potential antitumor properties by different postulated mechanisms such as suppressing cancer cells proliferation via its anti-inflammatory effects; decreasing the cancer stem cell populations; blocking specific oncogene signaling pathways; exerting antiangiogenic effects; and modulating the tumor microenvironment.

The good bioavailability by the oral route and good historical safety profile makes propolis an ideal adjuvant agent for future immunomodulatory or anticancer regimens.”
