Turmeric (curcuma longa), a member of the ginger family, is believed to have medicinal properties because it inhibits production of the inflammation-related enzyme cyclo-oxygenase 2 (COX-2), levels of which are abnormally high in certain inflammatory diseases and cancers, especially bowel and colon cancer. In fact, a pharmaceutical company Phytopharm in the UK hopes to introduce a natural product, P54, that contains certain volatile oils, which greatly increase the potency of the turmeric spice.
The anti-cancer effects of turmeric and curcumin have been demonstrated at all steps of cancer formation: initiation, promotion and progression. In addition to inhibiting the development of cancer, data obtained from several studies suggest that curcumin can also promote cancer regression when cancer is present. The protective effects of curcumin are only partially explained by its direct antioxidant effect. Other anti-cancer effects noted include the ability to: inhibit the formation of cancer-causing nitrosamines; enhance the body's levels of anti-cancer compounds such as glutathione; and promote the proper detoxification of cancer-causing compounds by the liver. Animal studies have shown that curcumin causes a marked decrease in the extent of prostate cell proliferation and a significant increase in prostate cancer cell apoptosis (death). The authors suggest that curcumin could be a potentially therapeutic anti-cancer agent, as it significantly inhibits prostate cancer growth.
