Does Green Tea Offer The Prescription For Beating Cancer?
With early detection, cancer is no longer an automatic death sentence. However, an initial diagnosis still brings with it a host of questions: What is the best course of treatment? Are conventional approaches best? For instance, in an article in the Canadian Medical Association Journal, Elizabeth Kaegi of the Task Force on Alternative Therapies of the Canadian Breast Cancer Research Initiative discussed the fact that cancer patients are trying a number of intriguing therapies, including Essiac, Iscador, hydrazine sulfate, vitamins A,C, and E, and 714-X. But perhaps one of the most popular therapies that has been tried is green tea.
Green tea is produced by steaming or frying the leaves of the shrub known as Camellia sinensis. The leaves, which are not fermented, are then dried. For 5,000 years, families in China and Japan have hailed green tea as a valuable stimulant and an effective remedy for stomach ailments. You can even purchase green tea in capsule form now, although the actual medicinal benefits from such capsules have yet to be established.
Dried tea leaves are far more complex than you might think. Specifically, they are made up of phytochemicals, plant alkaloids, proteins, carbohydrates, fiber, phenolic acids, and minerals. Of course, the exact composition of the leaves varies, depending on when the leaves are harvested and how they are processed. You should also be aware of the fact that the composition of green tea varies from that of black tea, since black tea has fewer polyphenols because of the fermentation process.
But what about treating cancer? Can green tea be as effective in treatment as it is in prevention? There has been some limited lab work investigating the possibility that green tea can be used as an alternative form of cancer treatment. However, at this point, there have only been a few animal studies and no human studies. The results of these studies are, at this point, inconclusive.
Yet, it should be noted that one study showed that, if extracts of green tea are applied to mouse skin, it appears to stop the development of skin cancer when known carcinogens have been applied to the skin. Other research indicates that green tea can stop the growth of tumors or decrease the number of tumors in animals that have been exposed to cancer-causing agents.
