DOES GINGER ROOT FIGHT CANCER?

OVERVIEW

Ginger is the thickened, pungent, aromatic rhizome of the plant Zingiber officinale. It has a long history of medicinal use. Chinese and Japanese people use ginger to treat varied human ailments, including stomach upset, diarrhea and nausea. There is some evidence suggesting that ginger root shows cancer preventive activity in experimental carcinogenesis. If you have cancer, speak with your doctor before using ginger supplements.

COLON CANCER

Ginger has attracted a great deal of interest because of its perceived ability to act as a chemopreventive agent. Ginger extract contains a number of biologically active substances, some of which have displayed anti-inflammatory and anti-cancer effects in many types of cells and animal models. Gingerol, the active component of ginger, has been shown to inhibit cell proliferation and have potent cancer chemopreventive effects in rat models of colon carcinogenesis, reports the U.S. Department of Health & Human Services.

LUNG CANCER

In a study led by W. Tuntiwechapikul, a professor of biochemistry at Chiang Mai University in Thailand, ginger was shown to down-regulate telomerase activity in A549 lung cancer cells. Telomerase is an enzyme that catalyzes the formation of DNA and RNA and plays a major role in the development of nearly all human cancers. The results, published in December 2010 in "Journal of Medicinal Food," showed that ginger exerts an anti-proliferative action through inhibition of multiple cell signaling pathways, including human telomerase reverse transcriptase, or hTERT, and c-Myc.

OVARIAN CANCER

Ginger root is a valuable source of biologically active compounds; some of these compounds may help prevent ovarian cancer, according to the University of Michigan Comprehensive Cancer center. Unlike normal cells, cancer cells are resistant to standard cancer treatments. It also appears that cancer cells can repair themselves more efficiently than normal cells. This is especially disturbing when radiation therapy and chemotherapy are the only means of cancer treatment. Laboratory and animal studies reviewed by the University of Michigan Comprehensive Cancer Research Center have shown that ginger can selectively kill ovarian cancer cells that cannot be destroyed by conventional chemotherapy agents.

CHEMOTHERAPY SIDE EFFECTS

Studies conducted by researchers at the University of Rochester Medical Center suggest that ginger helps alleviate side effects in patients undergoing chemotherapy. One study found that ginger improved chemotherapy-induced nausea by 40 percent, reports Julie L. Ryan, Ph.D., an assistant professor of dermatology and radiation oncology at Rochester's James P. Wilmot Cancer Center. A placebo-controlled, double-blinded study of 644 cancer patients reported that those who consumed ginger in addition to taking anti-nausea medication had fewer attacks of nausea than the group of people who received only medication.
