Does Pu-erh tea nourish stomach?

Needless to say, the benefit of Pu-erh tea on human health and health care. Among them, it is known that cooked tea can nourish the stomach, so is there any scientific basis for the stomach nourishing benefit of cooked tea? How exactly does it manifest?

The principle of Pu-erh cooked tea to nourish the stomach.
1. After fermentation, cooked tea has a large amount of derivatives, which are basically small molecules, which are beneficial to the absorption of the human gastrointestinal tract and have little irritation.

2. The pectin substance contained in cooked tea is much higher than other teas. It not only embodies good adsorption, but also can bind and eliminate bacterial toxins and other harmful substances in the body, such as lead, mercury and radioactive elements in heavy metals, play a detoxification role; at the same time it can protect the gastric mucosa and help digestion.

3. The key point of Pu-erh cooked tea to nourish the stomach is the quality of fermentation. Someone has done such an experiment: brew three tea samples of green tea, Pu-erh tea (three-year cooked tea), Pu-erh tea paste, and then put three cups of tea soup in the refrigerator to refrigerate. When the temperature of the tea soup drops to about 5 degrees above zero, take it out and observe whether the tea soup changes. At this time, we will find that the tea soup of green tea has a lot of milky suspension, which is the most turbid, because the pectin is reduced; the second is that Puer tea has a small amount of milky suspension, the color of the tea soup is brown, dark, and not transparent The reason is also the reduction and polymerization of macromolecules that have not been completely decomposed during the fermentation process; the best should be Pu-erh tea paste, which has no visible suspended matter and impurities. The color of the tea soup is slightly darker than when it was just brewed.

This experiment tells us that unfermented tea contains many macromolecular substances. After the temperature of its tea soup is lowered, it leads to a chemical reaction of the reduction and polymerization of the substance, which causes heavy turbidity. The slight turbidity of Pu-erh tea is due to insufficient fermentation process, and many substances are not fully degraded. Pu-erh tea ointment is a product of deep processing of Pu-erh tea, almost all of which are small molecules. Although it also has reduction and polymerization, the result is the polymerization of small molecules, but the tea soup appears dark.

We can also use this method to detect the "year" of naturally fermented Pu-erh tea. The shorter the "year", the more turbidity, and the longer the "year", the less turbidity. The “old tea” that has been aged for more than ten years should not have suspended matter and impurities visible to the naked eye, and the soup color will become more and more transparent as the year increases. This is also the reason why the longer the Pu-erh tea, the more transparent the soup color! However, it should be noted that the change in soup color will not be too obvious for "old tea" over 30 years old.

Therefore, the most nutritious way to drink Pu-erh cooked tea is to drink a cup of warm cooked tea soup on an empty stomach every morning, preferably Pu-erh tea paste or Puerh cooked tea of ​​good quality over three years. If conditions permit, it is better to drink Pu-erh raw tea that has been naturally fermented for more than ten years. Especially for those with excessive stomach acid, or suffering from gastritis and gastric ulcer, if you add a spoonful of honey to drink, the benefit of nourishing the stomach is more obvious.
