Tea is a tropical and subtropical plants that are scientifically known as
Camellia Sinensis. Of the approximately 3000 types of tea result of
interbreeding, obtained three kinds of tea outcome of the process, namely
green tea, oolong tea and black tea. Tea processing is the way with
chopped tea leaves and dried in the sun so that the chemical changes
before being dried. Such treatment will cause the leaves 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. The
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-catechin (EC), Epigallo-catechin (EGC), catechin Epigallo-gallate
(EGCG), and quercetin is commonly found in tea. EGCg and quercetin is a
powerful antioxidant with the 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 since 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 2
cups of tea a day or less. Other reports mention more of black tea
consumption is associated with low heart attack cases. John Folts,
director of the Medical School, 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 states that fanatical tea drinkers had higher levels of cholesterol
and low blood pressure, although it remains unclear whether it was
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 help prevent tooth decay. In a laboratory study in
Japan, researchers found that tea helps prevent formation of dental
plaque and kill bacteria cause inflammation of the gums.

Study in Japan showed that pendudukanya tea producing area known as a
fanatic tea drinker, very low mortality rate due to cancer. Another
study, undertaken in collaboration between the research team 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 that did not get a green
tea extract.

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