There is a process called pile fermentation in the production of Pu 'er tea, which is the most critical step to form the quality characteristics of Pu 'er tea, because in this process, Pu 'er tea will produce many microorganisms beneficial to human body, such as Aspergillus Niger, which makes Pu 'er tea taste smooth and mellow.
From the natural classification, the sun-cured finished tea without composting fermentation is commonly known as Pu 'er raw tea. Pu 'er tea made by artificial fermentation is commonly known as Pu 'er cooked tea.
As far as efficacy is concerned, both kinds of tea have many health-care functions. Raw tea can mainly clear intestines, reduce blood fat, refresh, lower blood pressure and lose weight, and is suitable for young people to drink. However, there are many active ingredients in raw tea, so it is not suitable for people who are prone to insomnia, people with colds and fever, patients with gastric ulcer and pregnant women. Cooked tea can reduce blood fat, blood pressure, prevent arteriosclerosis, prevent constipation, diuretic and nourish the stomach, which is more suitable for middle-aged and elderly people and people with cold stomach.
What are the different effects of raw Pu 'er tea and cooked Pu 'er tea?
Although both raw Pu 'er tea and cooked Pu 'er tea have health care functions, we also need to pay attention to the taboo of drinking Pu 'er tea:
1, it is not advisable to drink strong tea on an empty stomach, but it is very pleasant to drink at any time. As the saying goes, "drinking tea on an empty stomach makes you flustered and it is difficult to fall asleep at night." Drinking tea on an empty stomach will dilute gastric acid, inhibit the secretion of gastric juice, hinder digestion, and even cause palpitation, headache, stomach upset, dizziness, upset and other "drunken tea" phenomena, and affect the absorption of protein.
2, Pu 'er tea is drunk with the bubble, avoid drinking Pu 'er tea overnight. After a long period of soaking, harmful substances such as heavy metals will be separated from tea, and a large number of tea polyphenols will be oxidized, which will make the color of tea cloudy and reduce the health care effect. In addition, Pu 'er tea soaked in thermos cups should not be drunk often, and Pu 'er tea should not be drunk overnight.
3. The freshly brewed Pu 'er tea is not suitable for drinking. From the point of view of nutrition, the newly brewed Pu 'er tea has not been placed for a period of time, and its nutrients have not been oxidized. Some elderly patients with gastric acid deficiency and chronic gastric ulcer may have adverse reactions after long-term drinking.
What are the different effects of raw Pu 'er tea and cooked Pu 'er tea?
It is very important to keep the tea set clean. Don't forget to wash the cups frequently when drinking Pu 'er tea. Some people who often drink Pu 'er tea like to have a thick layer of "tea dirt" in their cups, and think that the Pu 'er tea brewed in this way tastes better. In fact, tea dirt is extremely harmful to human health. It contains a variety of heavy metals, which are brought into the body when drinking tea, hindering the absorption of nutrients, and also contains some carcinogens. Therefore, the tea scale on the inner wall of Pu 'er tea utensils should be cleaned in time to avoid its harm to health.
5. It is forbidden to drink Pu 'er tea for a long time, and it is not appropriate to drink Pu 'er tea intermittently. It should be fine and continuous, otherwise it is difficult to play a healthy and upward role. Hua Tuo, an ancient famous doctor, put forward the argument of "bitter tea for a long time, benefiting from thinking and meaning" in On Food.
6. Pu 'er tea should be drunk warm, not cold and hot. The temperature of drinking Pu 'er tea should be 25~50 degrees, not more than 60 degrees. Drinking cool Pu 'er tea often will have side effects on people's mouth, throat and stomach, especially those with poor spleen and stomach. Therefore, we advocate warm drinking for health.
