1. Lower blood pressure
Pu'er tea contains tea polyphenols, vitamin C, vitamin P and other substances are effective substances to lower blood pressure, taking tea polyphenols as an example, it can directly act on capillaries, improve capillary function, can significantly inhibit angiotensin-converting enzyme activity, and reduce blood pressure.
2. Lose weight and reduce lipids
The tea polyphenols in Pu-erh tea can significantly inhibit the rise of cholesterol and triglyceride content (both of which are the main components of blood lipids) in the body, promote the excretion of lipid compounds from the body, and improve the elasticity of capillary walls. Therefore, Pu'er tea has a certain effect on the prevention and treatment of atherosclerosis, hypertension and obesity.

3. Enhance immunity
Ripe Pu'er tea has catechocyanin (TR), chrychachin (TF), theabrownin (TB), gallic acid and vitamin C, which play an important role in improving the function of the body's immune system. The theaphytic oxyacids in Pu-erh tea can make blood immune cells resist external invasion in the human body, so Pu-erh tea has the effect of improving immunity and maintaining health.
4. Warm the stomach and nourish the stomach
Ripe Pu-erh tea is relatively mild, and rich in beneficial bacteria, viscous, smooth, mellow ripe Pu-erh tea will not irritate the stomach after entering the human body, and will form an attachment film on the surface of the stomach, producing a beneficial protective layer for the stomach. Therefore, long-term drinking of Pu'er tea can warm the stomach and protect the stomach.

5. Anti-aging
The lipid peroxidation process in the human body is one of the mechanisms of human aging, and the vitamin C, vitamin E, tea polyphenols, and catechins contained in Pu-erh tea all have antioxidant effects and can delay the aging process.
6. Healthy teeth and mouth protection
Professor Cao Jin of Hunan Medical University used Pu'er Jianzhi Tea to inhibit the adhesion of Proteococcus, and found that Puerh Jianzhi Tea has the effect of antibacterial plaque formation, and the best effect is achieved at a concentration of 1%.

7. Anti-cancer
The Chinese Academy of Preventive Sciences has conducted in vivo and in vitro tests on more than 140 kinds of tea, and a large number of data have affirmed the anti-cancer and anti-mutagenic effects of tea. The polyphenolic compounds and catechins in tea can inhibit some enzymes that can activate carcinogens, and can also change their activity with the final carcinogenic metabolism of electrophiles, thereby reducing the initiation and promotion of proto-oncogenes and reducing the number of final carcinogens. Studies have shown that Pu'er tea has the most prominent anticidal effect on cancer cells among many teas, and the concentration of one percent of tea that ordinary people drink has a significant effect.
8. Hangover
The liver needs vitamin C as a catalyst in the hydrolysis process of alcohol, and drinking Pu'er tea can supplement vitamin C, which is conducive to the decomposition of alcohol in the liver. On the other hand, the diuretic effect of caffeine in tea leaves makes alcohol quickly excreted from the body, and at the same time, it can stimulate the brain center that is in a state of inhibition due to alcohol, thus playing an anti-hangover effect.

9. Diuresis
Caffeine and theophylline contained in tea play a significant diuretic role by dilating the microvessels of the kidney, increasing renal blood flow and inhibiting the reabsorption mechanism of tubular water.
10. Improve dull complexion
Pu'er tea can quench thirst, relieve heat, detoxify, defecate, accelerate blood circulation, and solve dull complexion and pigmentation caused by poor qi and blood.

Although Pu'er tea is good, you should pay attention to the following points when drinking tea:
1) Do not drink tea on an empty stomach
There is nothing in the stomach, drinking tea on an empty stomach will inhibit gastric acid secretion, cause indigestion in the lightest, and the caffeine contained in the tea stimulates the body, aggravates the workload of the kidneys, and is not good for the body.
2) Don't drink overnight tea
Pu'er tea can be drunk as you brew, and it is forbidden to drink Pu'er tea overnight. After a long brewing of Pu'er tea, harmful substances such as heavy metals will be precipitated in the tea, and a large amount of tea polyphenols will be oxidized, which will make the tea color turbid and reduce the health care effect.

3) Don't drink tea immediately after a full meal
After eating a full meal, stomach acid needs it to digest and decompose food, at this time drinking tea, it will dilute the stomach acid, which will also lead to poor digestion and poor absorption, it is recommended to drink tea half an hour to an hour after meals.
4) Do not drink tea 2 hours before bedtime
It is best not to drink Pu'er raw tea 2 hours before bedtime, it will cause mental excitement, affect sleep, and even insomnia, but you can drink a small amount of mild ripe tea.

5) Don't drink strong tea
The polyphenols and theophylline substances contained in tea will have a stimulating effect on the body, and the higher the concentration of tea, the greater the stimulating effect, increasing the burden on the stomach and kidneys.
The above are the efficacy and role taboos of drinking Pu'er tea, although the tea is good, it must not be drunk excessively.
