Our country’s people have been circling such a proverb: “A cup of tea in the morning, starving to sell drugs,” shows that the health benefits of tea are extraordinary. Tea is an ancient Chinese article, many people like to drink, it can give the body to add a certain amount of nutrition, but also to relieve the lack of efficacy, but on the health of drinking tea, the ten kinds of tea can not drink.

喝茶

First, deterioration of tea

Tea is not easy to keep, easy to absorb moisture and mildew, and some people save for the love of tea, could not bear to discard the moldy tea. Deteriorating tea contains a lot of harmful substances and germs that cannot be consumed. If the tea leaves are left for too long after being soaked, the tea soup will also deteriorate due to oxidation and micro-organisms. Such tea cannot be used again.

Second, the first tea

Because modern tea is inevitably contaminated by pesticides, fertilizers, dust, and other substances during the process of planting, processing, and packaging. The first tea is actually the water for washing tea. It should be poured out as soon as possible after the water is poured out. The tea that is soaked is the most hygienic tea.

Third, burnt tea

The tea that has been overcooked has lost its nutrition and its taste is not good.

Fourth, long tea

The brewing time is too long, tea polyphenols, lipids, aromatic substances, etc. can be automatically oxidized, not only the tea soup is dark, bad taste, low aroma, loses taste value; but also due to vitamin C, vitamin P, amino acids in tea leaves. Reduced by oxidation, the nutritional value of tea soup is greatly reduced; at the same time, due to the shelving of tea soup for too long, it is polluted by the surrounding environment, and there is a large number of microorganisms (bacteria and direct bacteria) in tea soup, which is unsanitary.

9. Overnight tea

In particular, tea that has changed taste, even if it does not taste bad, it also breeds and breeds a large number of bacteria. Because tea contains a large amount of protein, most of it is insoluble in hot water, and remains in the leaves. When the water temperature is high, the protein on the tea will rot, and once it is left for a night, there will be a strain of bacteria that grows in the tea. Residual tannins become irritating, powerful oxides that stimulate the stomach and cause inflammation. Therefore, overnight tea is not suitable for drinking.

Of course, undisturbed overnight tea still has its role in medical treatment. Such as: overnight tea is rich in acid, fluoride, can prevent capillary bleeding; such as suffering from stomatitis, tongue pain, rash, bleeding gums, skin bleeding, sore mouth and other available overnight tea treatment; eyes appear red or regular Tears, wash your eyes several times a day with an overnight tea, can play miraculous effects; before and after brushing your teeth every morning or after eating, a few sips of tea overnight, not only can make your breath fresh, but also the role of solid teeth, and so on.
