Zhang Zhongjing, a medical sage, said, "Tea is very effective in treating purulent blood." Modern medical research has confirmed that tea is a good medicine for treating intestinal diseases. Polyphenols in tea can solidify and precipitate protein. Tea polyphenols combined with single-celled bacteria can coagulate eggs and kill bacteria. Such as harmful cholera bacteria, typhoid bacilli, Escherichia coli and so on. Soak in strong tea soup for a few minutes, and most of them will lose their ability to move. Therefore, Chinese medicine and folk often use strong tea or ground green tea to treat intestinal diseases such as bacillary dysentery and enteritis.
The administration method is to prepare 3g of tea leaves and a bowl of hot water, put them in a pot and decoct them three times a day, or use strong tea and 20g of vinegar three times a day. These methods are very beneficial to prevent intestinal transfection.
In addition, the side effects of drinking tea regularly are as follows:
1, often drink a lot.
Drinking a lot of strong tea often leads to a lot of discomfort, such as easy dilution of gastric juice and inability to digest normally. The normal gastric juice secreted by a person every day is 1.5-2.5 liters, which can reasonably digest the food that a person takes in every day. When drinking a lot of strong tea, it will dilute the gastric juice, reduce the concentration of gastric juice, make the gastric juice unable to digest food normally, and cause indigestion, abdominal distension, abdominal pain and other symptoms, and some even cause duodenal ulcer.
2. Tea hinders the absorption of iron by the body.
Tea contains tannic acid, black tea contains about 5%, and green tea contains about 10%. When people drink a lot of strong tea, the combination of tannic acid and iron will be more active, which will bring obstacles and influence to the absorption of iron and cause iron deficiency anemia.
3. Drinking strong tea is easy to constipation.
Tannic acid in tea can not only combine with iron, but also with protein in food to form massive tannic acid protein, which is difficult to digest and absorb, leading to constipation. For the elderly with constipation, constipation will be more serious.
Strong tea can lead to high blood pressure and heart failure.
Caffeine in strong tea can make the human heart beat faster, thus raising blood pressure; At the same time, a large amount of strong tea liquid enters the blood vessels, which can increase the burden on the heart, produce discomfort symptoms such as chest tightness and palpitation, and aggravate the degree of heart failure. Everything is measured. Drinking light tea can keep you healthy, while drinking strong tea is harmful to your health.
