Does Green Tea Offer The Prescription For Beating Cancer



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? or​ are nontraditional therapies preferable—particularly if​ the​ cancer does not seem to​ respond to​ chemotherapy and​ radiation.
In recent years, a​ great deal of​ emphasis has been placed on unconventional therapies for​ cancer. 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​ 714X. But perhaps one of​ the​ most popular therapies that has been tried is​ green tea. in​ fact, go to​ your local convenience store and​ you may find jug after jug of​ green tea in​ assorted flavors. Still, you may be wondering what makes green tea so special—and if​ it​ really can help to​ combat cancer.
Green Tea—The Basics
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.
Side Effects
Green tea can contain anywhere from 10 to​ 80 milligrams of​ caffeine—the actual amount depends on how it​ has been produced and​ stored. Since caffeine is​ a​ known stimulant, green tea may lead to​ a​ racing heart rate and​ insomnia. as​ a​ result, heart patients, pregnant women, and​ nursing mothers should ideally drink no more than two cups of​ green tea a​ day.
Cancer Prevention
Numerous scientific studies have explored the​ use of​ green tea as​ a​ cancer preventative. According to​ Kaegi, digestive cancers appear to​ be particularly responsive to​ green tea. in​ fact, such tea appears to​ somewhat decrease the​ risk of​ experiencing cancer of​ the​ digestive tract. Given the​ fact that such conclusions are the​ result of​ a​ number of​ epidemiological studies, it​ appears that the​ idea that green tea can prevent cancer has some merit.
News from the​ Lab
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​ cancercausing agents.
In some animals, green tea and​ tea extracts prevented cancer cells from metastasizing. There are also indications that green tea extracts can prevent chromosomal abnormalities that can lead to​ cancer, as​ well as​ reduce the​ size of​ breast and​ prostate tumors.
The Magic of​ EGCG
Green tea contains an antioxidant known as​ epigallocatechin gallate, or​ EGCG. This substance appears to​ inhibit enzymes which are responsible for​ cell replication, stop the​ adhesion of​ cells, and​ disrupt the​ communication pathways which enable cell division to​ occur. However, EGCG seems to​ be most critically important as​ an antioxidant.
Final Conclusions
Researchers believe that there is​ evidence to​ suggest that green tea can be used to​ treat cancer. However, scientists add that additional research is​ absolutely essential in​ order to​ determine the​ full range of​ treatment that green tea might provide. for​ instance, researchers must determine which cancers are most likely to​ be abated through the​ use of​ green tea or​ green tea extracts. Since there is​ also evidence to​ indicate that green tea can prevent cancer as​ well, drinking green tea is​ not only safe—it’s also highly recommended by some medical experts. Therefore, green tea may not just be a​ thirstquencher—it may also be a​ key ingredient of​ a​ healthy diet.
