Tea for health

Tea is a tropical and subtropical plants that are scientifically known as Camellia Sinensis. From approximately 3000 types of tea result of intermarriage, obtained three kinds of tea outcome of the process, namely green tea, oolong tea and black tea. The way is with chop tea processing tea leaves and dried in the sun so that the chemical changes before being dried. The treatment will cause leaf color to brown and gives black tea flavor characteristics.

Green tea, the oldest type of tea, especially well-liked by the people of Japan and China. Here the tea leaves have little processing, heating and drying so that only green leaf color can be maintained. Whereas oolong tea is more a kind of transition between black tea and green tea. These three types of tea each have health benefits because they contain so-called biochemical bond polyfenol, including flavonoids. Flavonoids are a group of antioxidants that are naturally present in vegetables, fruits, and beverages such as tea and wine.



Subclass of polyphenols including flavonols, flavones, flavanon, anthocyanidins, catechins, and biflavan. Derivatives of catechins such as epi-cathecin (EC), Epigallo-cathecin (EGC), cathecin Epigallo-gallate (EGCG), and quercetin is commonly found in tea. EGCG and quercetin is a powerful anti-oxidant power of up to 4-5 times higher than vitamin E and C, which also are potent antioxidants. Antioxidants are known to prevent cells from damage considering each cell damage will contribute more than 50 diseases.

Green tea contains EGCG, as well as black tea, says a biochemist. In a study by Dutch researchers say, consume 4-5 cups of black tea each day will reduce the risk of stroke by 70% compared with those who consumed two cups of tea a day or less. Other reports mention more of black tea consumption was associated with lower heart attack cases. John Folts, director of the Medical School, the Central Artery Thrombosis Research and Prevention, University of Wisconsin, USA to find the key properties of flavonoids in tea. Research results showed that flavonoids in black tea can inhibit the clotting of blood platelet cells thus preventing the clogging of blood vessels in hantung coronary disease and stroke. Another study mentioned that fanatical tea drinkers had higher levels of cholesterol and low blood pressure, although it remains unclear whether these things were directly caused by the tea.

Researchers at Case Western Reserve University, Cleveland, USA to find the effect of the use of green tea on the skin up to 90%. It turned out that tea is very effective in protecting the skin from the sun can cause skin cancer. Tea also contains fluoride which is known to strengthen tooth enamel and helps prevent tooth decay. In a laboratory study in Japan, the experts found that tea helps prevent formation of dental plaque and kill bacteria cause inflammation of the gums.

Research in Japan showed that pendudukanya tea producing region known as fanatic tea drinker, very low mortality rate due to cancer. Another study, carried out cooperation between research teams Oguni and cancer research center in Beijing to study the effects of green tea extract on mice that had been given food rations carcinogenic (cancer-triggering substances). Reportedly, the average rate of cancer in mice that received green tea extract half of the mice who did not obtain a green tea extract.

The researchers believe that the polyphenols known as cathecin found in green tea, helps the body fight cancer cells. Another study conducted by Dr Oguni and. Masami Yamada of Hamamatsu Medical Center found cathecin Helicobator kills pylori, the bacteria trigger stomach cancer.
