Benefits of Green Tea for Health

Green tea is a type of tea made from leaves of Camelia sinensis only, which suffered minimal oxidation during the manufacturing process. Green tea comes from China, and is associated with Eastern cultures.

Green tea is served with green tea leaves soaking in hot water in the cup. Depending on the quality of tea, the better the quality the less time it takes to soak. Usually the time required to soak the green tea is 30 seconds to 3 minutes, with water temperatures between 61-87 ° C. When the water is too hot or too long soak, then the resulting tea will taste bitter.

Green tea contains caffeine. The caffeine content will be reduced proportional to the length of time of immersion and temperature of water used. In addition, green tea also contains theophylline and theobromine.

Drinking green tea has long been associated with various health benefits.

Some scientific studies also support this. A study conducted at the Tohoku University of Japan in 2006 and listed in the Journal of the American Medical Association concluded that green tea may reduce mortality from cardiovascular disease.

In addition, several scientific studies have proven the efficacy of green tea in fighting heart disease, cancer, heart artery plaque formation, stress, obesity, high cholesterol, rheumatoid arthritis, and HIV infection (in vitro, has not been proven in humans).

However, green tea also has side effects, ie, oxidative stress and liver toxicity at a particular dose, therefore it is not excessive in taking it. Pregnant women should not drink green tea. It is also necessary to note that in general tea may inhibit the absorption of certain drugs, so it needs to be a distance of about 2 hours between taking the drug with a cup of tea
