From the perspective of traditional Chinese medicine, green tea is slightly cold, which helps to reduce fire. People with hot constitution and stomach fire can drink it properly, which can clear heat and reduce fire. When brewing green tea, the water temperature should be controlled at about 80℃ ~ 90℃. If you brew green tea, be careful not to soak it too thick, otherwise it will affect the secretion of gastric juice. Green tea should be drunk lightly. But people with cold stomach should drink less.

Green tea is one of the main tea leaves in China, which refers to a beverage made from the new leaves or buds of tea trees without fermentation, and through the processes of enzyme fixation, shaping and drying. The color of the finished product and the brewed tea soup retain the green style of new tea. Drinking green tea regularly can prevent cancer, reduce fat and lose weight, and also reduce the harm of nicotine to smokers.

Without fermentation, green tea retains the natural substances of fresh leaves, and contains many nutrients such as tea polyphenols, catechins, chlorophyll, caffeine, amino acids and vitamins. These natural nutrients in green tea have special effects of anti-aging, anti-cancer, sterilization and anti-inflammation, which are beyond the reach of other teas.
