Benefits from Green Tea


Cancer

• Breast cancer A recent Japanese study explored in greater detail the epidemiological findings on green tea's protection against breast cancer. In this case, women with stage I, II and III breast cancer were assessed in terms of their green tea consumption. It was found that "premenopausal women who consumed more green tea had a lower number of lymph node metastases. In postmenopausal women greater consumption of green tea correlated with increased expression of the estrogen and progesterone receptor, which implies more differentiated tumor cells and better prognosis." Finally, in a seven-year follow it was found that "women with stage I or II cancer who consumed five or more cups of green tea a day had approximately half the recurrence rate of those women who consumed four cups or less." Researchers at the Department of Surgery, Division of Oncology and. Center for Human Nutrition, University of California found that Inhibition of VEGF transcription appeared to be one of the molecular mechanism(s) involved in the antiangiogenic effects of green tea, which may contribute to its potential use for breast cancer treatment and/or prevention.

• Colorectal cancer Department of Medicine, Case Western Reserve University reserachers found that green tea constituent epigallocatechin-3-gallate inhibits topoisomerase I activity in human colon carcinoma cells. DNA topoisomerases I and II are essential for cell survival and play critical roles in DNA metabolism and structure. Inhibitors of topoisomerase constitute a novel family of antitumor agents with demonstrated clinical activity in human malignancies. The clinical use of these agents is limited due to severe toxic effects on normal cells. Therefore, there is a need to develop novel, nontoxic topoisomerase inhibitors that have the ability to spare normal cells. Recent studies have shown that green tea and its major polyphenolic constituent, epigallocatechin-3-gallate (EGCG), impart growth inhibitory responses to cancer cells but not to normal cells. Based on the knowledge that EGCG induces DNA damage, cell cycle arrest, and apoptosis, the reserachers considered the possibility of the involvement of topoisomerase in the antiproliferative response of EGCG. Here, for the first time, we show that EGCG inhibits topoisomerase I, but not topoisomerase II in several human colon carcinoma cell lines. Based on this study it is tempting to suggest that combination of EGCG with other conventional topoisomerase inhibitors could be an improved strategy for treatment of colon cancer. They concluded the role of EGCG as a chemotherapeutic agent needed to be investigated. The Laboratory for Cancer Research at the College of Pharmacy of, Rutgers University studied the effects of green and black tea polyphenols on normal human colon mucosa and colon cancers were investigated. The results indicated that tea polyphenols can affect arachidonic acid metabolism in human colon mucosa and colon tumors, and this action may alter the risk for colon cancer in humans.

• Esophageal cancer A study done by the College of Pharmacy, Rutgers, The State University of New Jersey, suggest that EGCG was converted to EGC in the oral cavity, and both catechins were absorbed through the oral mucosa through drinking green tea rather than using extracts. Because of the possible application of tea in the prevention of oral and esophageal cancers, the salivary levels of tea catechins were determined in six human volunteers after drinking tea. Saliva samples were collected after thoroughly rinsing the mouth with water. After drinking green tea preparations equivalent to two to three cups of tea, peak saliva levels of (-)-epigallocatechin (EGC; 11.7-43.9 microg/ml), EGC-3-gallate (EGCG; 4.8-22 microg/ml), and (-)-epicatechin (EC; 1.8-7.5 microg/ml) were observed after a few minutes. These levels were 2 orders of magnitude higher than those in the plasma. Taking tea solids in capsules resulted in no detectable salivary catechin level. Holding an EGCG solution in the mouth resulted in EGCG and EGC in the saliva and, subsequently, EGC in the urine. The present results suggest that slowly drinking tea is a very effective way of delivering rather high concentrations of catechins to the oral cavity and then the esophagus.

• Leukemia another study found that green tea extract is a potent nucleoside transport inhibitor, interfering with tumor cells' repair of DNA after chemotherapy. Thus green tea extract "markedly potentiated" the effectiveness of chemotherapy. These findings suggest that epigallocatechin gallate and green tea extract could be used as a nontoxic adjuvant therapy for leukemia. It would also be interesting to examine how green tea polyphenols synergize with such established anti-leukemic alternative treatments as retinoic acid, Vitamin D3, DMSO, curcumin and esculetin.

• Liver cancer A more recent study, done at the Fels Institute for Cancer Research at Temple University in Philadelphia, found that the addition of .5% of instant green tea powder to the diet of rats changed the metabolism of aflatoxin toward the formation of non-toxic hydroxylated metabolites, and decreased the binding of aflatoxin to liver-cell DNA, significantly decreasing the resulting number of pre-cancerous cells. The authors conclude that green tea protects against aflatoxin-induced liver cancer. Green tea also inhibited liver damage caused by exposure to 2-nitropropane. Even more important, green tea also protected against liver injury caused by galactosamine, which happens to be an animal model of viral hepatitis.

The benefits of green tea contains the healing process and prevent diseases such as cancer, heart disease, rheumatoid arthritis, multiple infections, immune dysfunction and cardiovascular disease. The benefits of green tea, so that the problem of high cholesterol, improve cholesterol levels in humans.

I admit that cancer patients must drink this tea because this is so beneficial for them.

Of course green tea is not one of the best, but it's best remedy for breast cancer & fat problem as well. I really appreciate or thanks to that team who find out this as a remedy...!
