Fruit farmers in the deep mountains reminded that drinking Pu 'er cooked tea with proper concentration will not stimulate the stomach. Sweet, smooth, sticky and mellow tea leaves will form a film after entering the human stomach, which will attach to the surface of the stomach and have a protective effect on the stomach! Therefore, drinking Pu 'er tea for a long time can nourish and protect the stomach. Pu 'er tea can also promote gastrointestinal peristalsis, so long-term drinking can help relieve constipation and prevent constipation. Drinking black tea can also nourish the stomach. I suggest drinking it in winter. When drinking, add a proper amount of red dates and longan to drink together, and the effect of nourishing the stomach will be better.
