Healthy Famous Tea

Antioxidants in tea are similar as those found in fruits and vegetables, such as vitamin A, C and E, which offer protection against free radicals that cause cell and gene damage. Tea polyphenols are are compounds in tea leaves that are natural plant antioxidant. Well known as a source for various nutrients and antioxidants, tea has gained even more popularity in modern times with claims of it's usefulness in fighting heart disease, cancer, obesity, tooth decay, nausea, and all manner of digestive disorders.Thirty percent of the dry weight of tea leaves is polyphenols, which cause the taste of tea. It was Dutch traders that first brought tea to Europe but the British who greatly developed it, transplanting it to India in the early 1800's.

Since the fifth century AD, tea has been exported by land and sea throughout Asia and reached Europe in 1610. It was originally taken as a detoxifying medicine though it grew to great social prominence during the Tang (620-907 AD) and Sung (960-1279 AD) Dynasties. It is thought to have first been discovered in the mountainous areas of China's far western Sichuan and Yunnan provinces. Historically, tea's origins date back to around 2700 BC.

The Benefits of Green Tea for Cancer and Leukemia

Green tea has long had many health benefits associated with it and its curative properties have been used in Chinese medicine for thousands of years.
EGCG is considered to be the most active component in green tea and is the best researched of all the green tea polyphenols. Tea polyphenols are classified as catechins and green tea contains six primary catechin compounds: catechin, gallaogatechin, epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin gallate (also known as EGCG). The more the leaves are fermented, the lower the polyphenol content and the higher the caffeine content. Green tea is made from unfermented leaves and is reputed to contain the highest concentration of polyphenols, chemicals that act as powerful antioxidants.

Green tea, black tea and oolong tea are all made with the leaves of the Camellia sinensis bush.
Several studies have suggested that green tea and green tea extract have cancer-fighting abilities, possibly because the tea's concentration of antioxidants such as EGCG help minimize the cell damage that can lead to cancer.
EGCG (the key antioxidant in green tea) has been shown to kill cancer cells taken from leukaemia patients and put in a test tube. A recent study conducted at the Mayo Clinic in Rochester, Minnesota has demonstrated the benefits of green tea in adult sufferers of leukemia.
The fourth patient who did not show an improvement in her cancer overall, still exhibited an increase in her white blood cell count. In the months after they started drinking green tea or taking green tea extracts, three of them showed measurable improvements in their condition. All four patients had CLL (chronic lymphocytic leukemia). All four patients had started using green tea on their own last year, after hearing media reports about its health benefits.

All four patients had started using green tea on their own last year, after hearing media reports about its health benefits. Doctors at the clinic reported that four patients had started using green tea on their own last year, after hearing media reports about its health benefits.
However, over the next year the patient's lymph nodes steadily reduced in size. Swelling of the lymph nodes is one of the characteristic symptoms of CLL. In one case, a patient had been showing progressive swelling in her lymph nodes before she starting taking green tea capsules twice a day.
However, the benefit of EGCG over methotrexate is that it has far fewer side effects. Both work by blocking the enzyme dihydrofolate reductase, which is essential to the growth of tumour cells. Researchers have found that EGCG, the anti-cancer compound in green tea, works in a similar way to the anti-cancer drug methotrexate. Other research has come up with an explanation for why regular green tea drinkers have a low incidence of gastric and oesophageal cancers.
Women seeking to conceive or who are already pregnant are advised to consult their medical practitioner about the risks associated with drinking green tea. However, in a study conducted at Kaiser Permanente Medical Care Program of Northern California in Oakland, researchers found that women who drank more than one half cup of caffeinated green tea every day doubled their odds of conceiving. This side effect could explain the increased risk of birth defects such as spina bifida.

The same study also showed that blocking the dihydrofolate reductase enzyme lowers folic acid levels.
