Green tea cancer cure disease

Conception with the tea as a substitute for drug therapy in a thousand year history has been in china. However, until recent years, European society began to realize the potential advantages tea for health. Now, people consider Europe as a tea to treat stress hormones, and drugs as various other diseases. Moreover, the results of this new research found that consuming a glass of tea every night may have a lower ratio of types of cancer diseases.

Does drinking green tea really help prevent cancer? The answer is still unclear, according to a review of 51 previous studies done over two decades.

The review, published online in the Cochrane Database of Systematic Reviews, found that green tea may offer some help against live cancer, breast cancer and, in men, prostate cancer, but consumption may actually increase one's chances of developing urinary bladder cancer.

Conflicting evidence was fround in the case of gastrointesnital (esophagus, colon or pancreas) cancers, though the authors noted "limited moderate to strong evidence" of green tea protecting against lung, pancreatic and colorectal cancer."

"Despite the large number of included studies, the jury still seems to be out on the question nf whether green tea can in fact prevent the development of various cancer types," lead review author katja Boehm, a member of the Unconventional and and Complementary Methods in Oncology Study Group in Nuremburg, Germany, said in a news release issued by the journal's publisher, The Cochrane Collaboration.

The researchers reviewed studies involving more than 1.6 million people in Asia, where green tea consumption is a regular habit. Boehm said that variables in how much green tea people drink and how different cancers grow makes it difficult to find a conclusive relationship about whether green te helps prevent cancer.

"One thing certain," she said, "Green tea consumption can never account for cancer prevention alone."

Green tea is rich in polyphenols, which include the powerful antioxidants called catechins. Though these polyphenols are in other black and ooloong teas, which come from the same plant, some claim the polyphenols in green tea have unique cancer-preventing abilities that prevent cell growth.
