According to a CBC News report, ancient druids believed mistletoe had magical properties because of the way it grows, never touching the ground and without taking nourishment from the earth. However, University Hospital of Wales in Cardiff researchers are warning there is nothing magical about the use of mistletoe extract for the treatment of cancer, and in fact, it can cause harm.

Serious side effects from the injection of mistletoe extract have been reported in the Christmas issue of the British Medical Journal, including a case concerning a 61-year-old woman who had a tumor-like growth develop under her skin, brought on when she self-injected herself with mistletoe extract. The researchers warn that the use of mistletoe extract has been shown to cause a severe allergic reaction, breathing difficulties, joint pain and kidney failure. Some studies have shown that mistletoe might actually lead to cancer growth.

Edzard Ernst, a professor of complementary medicine at the Universities of Exeter and Plymouth is quoted as saying, "The idea that mistletoe may help treat cancer is based on that the idea that mistletoe, like cancer, is a parasitic growth that eventually kills its host." The researchers of this published study indicated that there are over 30 mistletoe extract preparations available in Europe, and its use by cancer patients is well-known.

From another source, the National Cancer Institute's overview of mistletoe includes the following:

• Mistletoe is a plant that grows on several types of trees and has been used since ancient times to treat many ailments.
• Mistletoe extract has been shown to kill cancer cells in the laboratory and to boost the immune system.
• Animal studies have suggested that mistletoe may be useful in decreasing the side effects of standard anticancer therapy.
• Many human studies using mistletoe to treat cancer have been done in Europe with unclear results, and a few clinical trials in the United States and abroad are in progress.
• Very few bad side effects have been reported from the use of mistletoe extract, though mistletoe plants and berries are poisonous to humans.
• The U.S. Food and Drug Administration (FDA) has not approved mistletoe as a treatment for cancer or any other medical condition.

Although researchers have considered the possibility that the bark of the White Birch tree might contain a compound, known as betulinol, with the ability to fight prostate cancer, until recently there was no way to test it because they did not know how to make the compound water-soluble.

Now that Weill Medical College of Cornell University researchers have solved that problem, laboratory tests on mice are showing it is indeed effective in killing prostate cancer cells.

"Years of research appear to have paid off, and now animal tests on this potential anti-cancer agent can finally proceed. Already, in mouse studies, we've found that our water-soluble compound - called Boc-lysinated-betulonic acid -- has achieved up to 92 percent inhibition of prostate tumor growth compared to controls," states lead researcher Dr. Brij Saxena.

While the study into the cancer-fighting properties of the White Birch tree might be new, the White Birch tree has a history of medicinal uses. According to the Living Memorials Project website White Birch tree information page, Native American Indians used the leaves and bark of the tree as a tea to treat fevers, stomach upset, and rheumatism. The bark was boiled to make poultices for minor wounds, and an oil made from the bark to treat bladder infections, rheumatism, gout and nerve pain. In Europe, the leaves were used to treat skin rashes, hair loss, rheumatic complaints, and to purify the blood. Birch tar oil was used to treat chronic skin diseases.

The Phytochemical and Ethnobotanical Databases of United States Department of Agriculture includes information on betulin and betulinic acid as showing that it inhibits cancer, and the compound is also known to be anticarcinomic; anti-flu; anti-inflammatory; antiviral; and a prostaglandin-synthesis-inhibitor.

I could eat pesto on just about everything. As a spread on warm bread, sauce over meats, drizzled over salads and into soups, and on pasta. So some good news for all you pesto lovers because it is extremely healthy aiding in digestion and boosting the immune system. It is good for gout, muscular aches and pains, rheumatism, and your respiratory system. Some studies show that basil is a cancer preventative herb. It also helps people with diabetes because it can lower blood sugar levels and aid insulin release.
