There have always been advocates of natural medicine for cancer, but the results have not always been what is desired. A new method of encapsulating one natural supplement as a nanoparticle makes it far more effective against cancer.

Luteolin is the cancer-fighting plant chemical you have probably never heard of.

Luteolin is the antioxidant that makes some kinds of pollen yellow. It is abundant in the Ayurvedic herb chebula, also known as haritaki and by its botanical name Terminalia chebula. It is found in artichokes, broccoli, celery, green pepper, parsley, dandelion, navel oranges, carrots, green onions, apple peel, perilla leaf, chamomile tea, olive oil, peppermine, rosemary, and oregano. It is also the main ingredient in some over the counter ethical natural supplements such as Lutimax.

Luteolin is one of just two plant chemicals (the other being quercetin, which is especially abundant in apple peels, green onions, and grapefruit) that is known to suppress a chemical in the body known as platelet-activating factor, or PAF. While some activity of PAF is essential to human health, since it is an important part of the body's ability to stop bleeding, the downside of PAF is that it also triggers allergic reactions, and it can be used by certain bacteria to create a blood clot that shields them from the immune system, and it part of the tools a cancerous tumor uses to "break out" and spread to the rest of the body.

Luteolin also can disrupt the cancer-causing changes in cells infected with certain viruses, such as the papillomavirus, which is causative of cervical, ano-rectal, and oral cancers. 

And luteolin stops the migration of cells in the linings of arteries that leads to atherosclerosis, as well as stopping one of the steps in inflammation of the brain that is associated with autism, Parkinson's disease, and Alzheimer's.

Scientists have known for years that in places where people eat lots of the vegetables that contain luteolin, there are lower rates of mesothelioma and lung, prostate, breast, ovarian, and stomach cancers. It doesn't take a lot of luteolin to make a difference. In one study, a single serving of vegetables containing luteolin and other similar plant chemicals a month was enough to a huge (nearly 50%) difference in the risk of developing mesothelioma after exposure to asbestos. 

Scientists have also known that luteolin stops cancer-causing processes both inside a cell, by interacting with specific segments of DNA in the nucleus and in the mitochrondria of the cell, and by stopping certain inflammatory processes that occur on the surface of the cell. Luteolin is an antioxidant in certain anti-cancer processes, but it is a pro-oxidant in others, especially those involving the "zapping" of cancer cells by the production of tiny amounts of hydrogen peroxide.

And that's where attempts to use luteolin as a cancer treatment have broken down. Luteolin in one dosage is an antioxidant, stopping chemical reactions that lead to the release of free radicals of oxygen inside the cell that damage DNA. And luteolin in another dosage is a pro-oxidant, generating free radicals of oxygen that kill lung cancer cells.

If you are relying on good diet or herbal medicine to provide the luteolin your body can use to fight cancer, it is hard to get the right dose for the right stage of your disease. Cancer prevention requires an antioxidant effect, and cancer treatment requires a prooxidant effect. Fortunately, Emory University scientists using nanotechnology have figured out a way to get the right dose of luteolin where it is needed.
