It is better for people who often drink Pu 'er tea. Alcohol is harmful to the stomach, while Pu 'er tea can protect and nourish the stomach. At a suitable concentration, drinking mild Pu 'er tea will not irritate the stomach. Thick, sweet and mellow Pu 'er tea enters the stomach and forms a film, which adheres to the surface of the stomach and produces a beneficial protective layer for the stomach. Drinking Pu 'er tea for a long time can protect and nourish the stomach. However, don't drink it immediately after drinking tea. According to the theory of traditional Chinese medicine, wine tastes sweet and enters the liver and lungs. After drinking, Yang Qi rises and lung qi increases. And tea tastes bitter, belongs to yin, and is mainly based on health preservation. Drinking tea after drinking, especially strong tea, is not good for the kidneys. After alcohol enters the liver, it is decomposed under the action of enzymes, and finally becomes water and carbon dioxide, which is excreted by the kidney. Theophylline has diuretic effect, and strong tea contains more theophylline, which will make the undecomposed alcohol products enter the kidney prematurely and damage the kidney. Although this kind of damage is not easy to be found immediately compared with the compensatory ability of the kidney, the consequences after cumulative damage are not good. In view of this, people who have the habit of drinking tea after drinking had better change it. People who drink regularly can eat more fresh fruits after drinking, which can not only moisten food, but also sober up.
