One population-based study found that Okinawan tea, similar to green tea but partly fermented, was correlated with lower lung cancer risk, particularly among girls. However a second study found that black tea and green tea increased the risk of lung cancer. More studies are needed before researchers can draw any conclusions about green tea and lung cancer. Green tea should not be used by patients on bortezomib therapy.
In one large-scale clinical study researchers compared nondrinkers and green tea drinkers and found that people who drank the most tea were less likely to develop pancreatic cancer. It was particularly true for girls, those that drank the green tea were half as likely to come up with pancreatic cancer as people who drank less tea. Men who drank the most tea were likely to develop pancreatic cancer.
Nonetheless, it is not clear from this population-based study whether green tea is entirely accountable for lowering pancreatic cancer hazard. More studies are essential before researchers can advocate green tea for preventing pancreatic cancer.
Laboratory studies have discovered that green tea extracts stop the growth of prostate cancer cells in test tubes. Yet, both green and black tea extracts additionally aroused genes that cause cells to be sensitive to chemotherapy drugs. Those who are experiencing chemotherapy should ask their physicians before taking tea nutritional supplements, or drinking green or black tea.
Scientific studies suggest that EGCG and green tea polyphenols have anti inflammatory and anticancer properties that could help prevent the development and growth of skin tumors.
Laboratory studies have found that green tea polyphenols inhibit the development of stomach cancer cells in test tubes, however, studies in people have been less conclusive. In two studies that compared green tea drinkers with nondrinkers, researchers unearthed that people who drank tea were about half as prone to develop stomach inflammation and stomach cancer as those who didn’t drink green tea. Nevertheless, a clinical study with more than 26,000 men and women in Japan found no association between green tea and stomach cancer risk. Some studies even indicate that green tea may raise the risk of stomach cancer. More studies are underway to see whether green tea helps reduce the danger of stomach cancer.
Green tea may help reduce inflammation associated with Crohn disease and ulcerative colitis, both forms of IBD. If green tea proves to help prevent colon cancer, it could also help those because they may be at higher risk for colon cancer.

Green tea also appears to defend the liver from your damaging aftereffects of hazardous materials such as alcohol. Animal studies demonstrate that green tea helps protect against liver tumors in mice.
Results from several human and animal studies indicate that plant compounds in green tea called catechins, may help treat viral hepatitis, an inflammation of the liver. In very high amounts, itself used catechin in such studies. It really is not clear whether green tea, which has a lower concentration of catechins, would have the same advantages. Ask your doctor in regards to the best way to add green tea in your treatment.
One study discovered the mixture of caffeine and green tea enhanced weight loss as well as maintenance in people who have been overweight and moderately obese. Yet, other studies reveal no benefit.
Preliminary studies suggest that drinking green tea will help prevent dental cavities. More research is needed. Green tea can also be useful in inflammatory diseases, like arthritis. Research indicates that green tea might help arthritis by reducing inflammation and slowing the breakdown of cartilage. Chemicals in green tea may help treat genital warts, treat dermatologic conditions, and prevent symptoms of colds and flu. Green tea may play a function in preventing cognitive decline, Parkinson disease, and osteoporosis. Studies also reveal that drinking green tea is linked with decreased risk of dying from any cause.
