The basic functions of Pu 'er tea are 1, lowering blood fat, losing weight, lowering blood pressure and resisting arteriosclerosis. Dr Emile Carobbi, clinical teaching director of Saint Antoine Medical College in Paris, France, used Yunnan Pu 'er tea to prove that "Yunnan Pu 'er tea has a good effect of reducing lipid content and cholesterol content". China Kunming Medical College also conducted 55 clinical trials on Yunnan Pu 'er Tuocha for the treatment of hyperlipidemia. Compared with 3 1 case of Antoine, a drug with better lipid-lowering effect, Pu 'er tea is more effective than Antoine. Drinking Pu 'er tea for a long time can lower cholesterol and glyceride, so drinking Pu 'er tea for a long time can treat obesity. Drinking Pu 'er tea can cause vasodilation, blood pressure drop, heart rate slowdown, cerebral blood flow reduction and other physiological effects, so it has a good therapeutic effect on patients with hypertension and cerebral arteriosclerosis. Pu 'er tea has a good effect on softening blood vessels, but it has a poor effect on promoting intestinal circulation and detoxification. 2, anti-cancer, anti-cancer scientists through a large number of people compared to prove that people who drink tea have a low incidence of cancer. Pu 'er tea contains a variety of rich anti-cancer trace elements, and Pu 'er tea has a strong killing effect on cancer cells. 3. Tooth-strengthening and tooth-protecting Pu 'er tea contains a variety of physiological active ingredients, which has the function of sterilization and disinfection, so it can remove the bad smell of the mouth and protect the teeth. 4. Protecting the stomach and nourishing the stomach At a suitable concentration, drinking mild Pu 'er tea does not stimulate the stomach. Thick, smooth and mellow Pu 'er tea enters the human stomach to form 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. This is the main reason why consumers who advocate drinking Pu 'er tea at home and abroad call Pu 'er tea "beauty tea" and "longevity tea". 5. Catechin in anti-aging tea has anti-aging effect. The total catechin content of Yunnan Daye tea is higher than that of other tea varieties, and its anti-aging effect is better than that of other teas. At the same time, during the processing of Pu 'er tea, macromolecular polysaccharides are transformed into a large number of new soluble monosaccharides and oligosaccharides, and vitamin C is multiplied. These substances play an important role in improving the function of human immune system, and have the effects of strengthening the body and prolonging life. 6. Radiation protection According to the research results of Pu 'er tea by He Guofan of Sun Yat-sen University in Guangdong Province, drinking 2% Pu 'er tea can alleviate the damage caused by cobalt 60 radiation. 7, sober up "Compendium of Materia Medica" contains: "Pu' er tea is the best treatment for oily pericardium, first scraping the intestines to sober up." Facts have proved that tea polyphenols in tea can promote ethanol metabolism and protect the liver. So that the ethanol metabolism can be carried out normally and smoothly. Drinking tea can increase vasoconstriction. Theophylline has diuretic effect, which can promote the rapid excretion of alcohol from the body and reduce the harm after drunkenness. Drinking tea can also supplement vitamin C needed for alcohol hydrolysis and excite the brain center anesthetized by alcohol. So as to play a role in hangover. Moreover, using tea to relieve alcoholism will never hurt the spleen and stomach, nor will it make drunken people vomit a lot and cause nausea. 8. Beauty Pu 'er tea can regulate metabolism, promote blood circulation, regulate human body and naturally balance internal functions, so it has beauty effect and is called "beauty tea" overseas. 9. Other wonderful uses of Pu 'er tea for improving eyesight: Tea residue after drinking in Qingpu can be used to warm eyes for a few minutes, which has the effect of improving eyesight for a long time. Especially for internet addicts and white-collar workers who have been facing computer monitors for a long time, this measure is particularly effective because Pu 'er tea has the function of radiation protection. Feet-nourishing: Boiled tea residue can be boiled to soak feet, because the boiled tea is warm, which can promote blood circulation of feet, make the whole body's meridians smoother, and prevent freezing and warm feet in winter. Especially middle-aged and elderly people. Health care efficacy For thousands of years, Pu 'er tea has been favored by consumers because of its excellent quality. At the same time, the unique flavor of Pu 'er tea is also related to its natural transformation process. After the cooked Pu 'er tea is processed by a special processing program, it is broken into tea balls of different sizes and shapes, which are naturally dried in the shade. Then according to the transportation requirements, put them into baskets and transport them to other places. Yunnan is located in the frontier of the motherland, and Xishuangbanna is located near Yunnan, with high mountains and dangerous clouds. In ancient times, traffic was extremely difficult, and the transportation of tea depended entirely on caravans and cattle gangs. There was a long delay on the mountain road. In some sections, caravan can only go twice a year, and cowherd can only go once a year. Tea leaves have been bumping on horses' backs and cows' backs for a long time, and the contents are slowly transformed, so that Pu 'er tea has its unique luster and mellow fragrance. The efficacy and function are doubled. The detoxification and therapeutic effects of Pu 'er tea are recorded in Brahma Record written by Chai Calyx in A.D. 1925, Compendium of Materia Medica, Interview with Simao, Tips of Physics, Herbal Mirror, News Record of Southern Yunnan and other ancient books collected in Qing Dynasty. In recent years, the physiological and pharmacological effects of Pu 'er tea have been further studied at home and abroad, and the functions of Pu 'er tea have been further developed. The new research found that Pu 'er tea has beauty efficacy, and is known as the "beauty upstart", which can deeply detoxify.

Can slim down and tighten the skin. Dr Emile Carobbi, director of clinical teaching at Santoni Medical College, made a clinical trial with Yunnan Pu 'er tea, which proved that "Yunnan Pu 'er tea has a good effect on reducing the contents of lipid compounds and cholesterol". Therefore, insisting on drinking Pu 'er tea can achieve the effects of losing weight, lowering blood fat and lowering blood pressure. The efficacy of Pu 'er tea lies in its mild nature, which warms the stomach without hurting it. This is especially obvious for cooked tea. Generally speaking, light fermented tea is really "unbearable lightness" for tea lovers, especially for modern people who drink tea all day and have an abnormal diet. Under the long-term immersion of caffeine and tannic acid, they often have the pain of scratching their stomachs. I believe many people have personal experience. Therefore, Pu 'er tea is especially suitable for friends who have a lot of entertainment. Most friends who drink too much have a cold stomach. Pu 'er tea has the unique function of warming the stomach, which makes the family drink well every day, and also makes him feel a love. Yunnan Pu 'er tea is a kind of tea, which is a sacred product for warming stomach, reducing blood fat, invigorating qi and prolonging life. Yunnan has the oldest tea tree king, which is also the origin of tea. As early as the late Ming and early Qing dynasties to Tongzhi years, the emperor and the royal family advocated drinking Pu 'er tea, which was also the prosperous period of Pu 'er tea. Pu 'er tea is a kind of post-fermented tea, which has the reputation of "longevity tea" and is also known as "drinkable antique". It can be stored for a long time, and the older it is, the more fragrant it will be. The research results of hypoglycemic function of Pu 'er tea were evaluated. Announced in Pu 'er City, Yunnan Province on the 27th: The research results of Pu 'er tea's hypoglycemic function have been appraised by Yunnan Science and Technology Department recently, which provides a strong theoretical support for drinking Pu 'er tea scientifically and preventing and treating type II diabetes. It is understood that diabetes is one of the most common chronic diseases, in which type II diabetes accounts for more than 90% of the total number of diabetic patients, and 30% of obese people in China suffer from type II diabetes. Studies have shown that type II diabetes is closely related to the abnormality (elevation) of a biological enzyme in human body, and this biological enzyme has gradually become one of the important targets for treating type II diabetes. Some research institutions and companies at home and abroad began to look for inhibitors of this biological enzyme, but at present there is no safe and non-toxic inhibitor for clinical use. According to experts' evaluation, drinking Pu 'er tea scientifically is helpful to prevent or assist in the treatment of type II diabetes and reduce the complications caused by type II diabetes. 1. Geographical indication: Pu 'er tea is unique to Yunnan. The unique geographical location has created the rich endoplasm of Yunnan tea, which is also the root of Yunnan Pu 'er tea. 2. Rich taste: The unique climate in different days in Yunnan has made Pu 'er tea "one mountain blindly" and "ten mountains and ten flavors". There are no similarities in shape, color, fragrance and quality between different producing areas. 3. Green food: Yunnan is a frontier province with backward industrial industry, and there are basically no chemical enterprises in many tea-producing areas. This also ensures the pollution-free and pure natural green quality of Yunnan Pu 'er tea. 4. The older the tea, the more fragrant it is: the long history and unique tea-drinking culture have created the characteristics of Yunnan Pu 'er tea. 5. Harmony between man and nature: Chen Fang, a natural place, has experienced the catalysis of wind, rain and time, and sublimated the connotation and taste of Yunnan Pu 'er tea, just like life. This is also the unity of nature and man in Pu 'er tea. 6. Personalized drinks: rich internal substances, distinctive fragrance and changeable taste make Pu 'er tea better meet the multi-level drinking needs of modern people. 7. Healthy drinks: A variety of tea elements and trace elements with high content and the best water solubility and release make Pu 'er tea synonymous with health. Yunnan Pu 'er tea is a kind of tea with strict requirements on the origin of raw materials, production technology and hygiene requirements. However, there is no uniform standard in aroma, taste and drinking method. This is why Pu 'er tea allows people of different ages, classes, skin colors and constitutions to find their favorite Pu 'er tea. Pu 'er tea is not only an inclusive tea, but also a distinctive tea. The effect of black tea is 1, refreshing and relieving fatigue. According to medical experiments, caffeine in black tea stimulates the cerebral cortex, stimulates the nerve center, and promotes the refreshing and concentration of thinking, thus making the thinking response more acute and enhancing memory; It also has an exciting effect on the vascular system and the heart, strengthens the heartbeat, thus accelerating blood circulation to facilitate metabolism, and at the same time promoting sweating and diuresis, so as to accelerate the excretion of old and waste substances such as lactic acid (a substance that makes muscles feel tired) in the body and achieve the effect of eliminating fatigue. 2. Drinking black tea in summer can quench thirst and relieve summer heat, because polyphenols, sugars, amino acids and pectin in tea react chemically with saliva, which stimulates saliva secretion, makes the mouth feel moist and produces a cool feeling; At the same time, caffeine controls the body temperature center of hypothalamus and regulates body temperature. It also stimulates the kidneys to promote the excretion of heat and dirt and maintain the physiological balance in the body. Besides, black tea is an excellent sports drink. In addition to relieving summer heat, quenching thirst and replenishing water, if you drink it before an exercise that requires physical strength and endurance (such as running a marathon), because caffeine in tea leaves has a refreshing effect, it can also make the body burn fat to supply heat energy while retaining liver vinegar during exercise, so people's endurance is stronger. Black tea 3, diuretic under the joint action of caffeine and aromatic substances in black tea, increase the blood flow of the kidney, improve the glomerular filtration rate, expand the renal microvasculature, and inhibit the reabsorption of water by renal tubules, thus contributing to the increase of urine volume. This is beneficial to eliminate lactic acid, uric acid (related to gout), excessive salt (related to hypertension), harmful substances and so on. And relieve edema caused by heart disease or nephritis. 4. Polyphenols in anti-inflammatory and bactericidal black tea have anti-inflammatory effects. Experiments show that catechins can combine with single-celled bacteria to coagulate and precipitate protein, thus inhibiting and eliminating pathogenic bacteria. Therefore, for patients with bacillary dysentery and food poisoning, drinking black tea is quite beneficial. People often use strong tea to smear wounds, bedsores and athlete's foot. 5. Detoxification According to experiments, tea polyphenols in black tea can adsorb heavy metals and alkaloids and make them precipitate and decompose, which is good news for modern people whose drinking water and food are polluted by industry. In addition, black tea also has the functions of preventing caries, invigorating stomach and moistening intestines, helping digestion, delaying aging, lowering blood sugar, lowering blood pressure, lowering blood fat, resisting cancer and radiation. People who nourish their stomachs will feel uncomfortable if they don't eat and drink green tea. This is because tea polyphenols, an important substance contained in tea, have astringent taste and have a certain stimulating effect on the stomach, especially on an empty stomach. On the other hand, black tea is made by fermentation and baking. Under the action of oxidase, tea polyphenols are enzymatically oxidized, and the content is reduced, which reduces the stimulation to the stomach. In addition, the oxidation products of these tea polyphenols can also promote human digestion, so black tea will not only hurt the stomach, but also nourish the stomach. Drinking black tea with sugar and milk often can diminish inflammation, protect gastric mucosa and have a certain effect on treating ulcers. Black tea brown black tea to fade, mainly depends on the amount of tea and water release. Ordinary people can put 3-5 grams of tea, and the light taste can be put less, ensuring the tea-water ratio of 1: 50. That is to say, if you put 3 grams of black tea, you should brew it with 150 ml of water. Black tea and porcelain cups have the best visual and taste effects. It is recommended that you brew each cup of tea for 3-5 minutes. Black tea is not suitable for cold drinks. If it is left for too long, it will affect the effect of warming the stomach and reduce the nutrients. It is best to make black tea in an open cup. Don't wait until the water in the cup is finished before heating the water. It is best to store water at about 65,438+0/3, so as to dilute the tea leaves and keep the temperature and concentration of the tea leaves appropriate. Every cup of black tea is stored for three times, and the taste is the best. Precautions for drinking black tea 1. General note: the newer the new tea, the better. Improper drinking methods can easily hurt the stomach. Because new tea has just been picked, it has a short storage time and contains more unoxidized polyphenols, aldehydes and alcohols, which has little effect on healthy people. But for patients with poor gastrointestinal function, especially those with chronic gastrointestinal inflammation, these substances will stimulate gastrointestinal mucosa, and people with poor gastrointestinal function are more likely to induce stomach diseases. Therefore, it is not advisable to drink more new tea, and do not drink new tea that has been stored for less than half a month. In addition, new tea contains more caffeine, active alkaloids and various aromatic substances, which will also excite people's central nervous system. Patients with neurasthenia and cardiovascular and cerebrovascular diseases should drink in moderation, not before going to bed or on an empty stomach. The correct way is to leave it for half a month before using it. Don't take medicine with tea; Do not drink tea before and after taking the medicine 1 hour. Ginseng and American ginseng should not be eaten with tea. Avoid drinking strong tea to relieve hangover; It is not advisable to drink tea before meals; Avoid drinking tea immediately after meals; Girls should avoid drinking strong tea. Do women drink black tea? Elegant Black Tea Banquet The American Heart Association once concluded that black tea is "one of the drinks rich in flavonoids, which can eliminate free radicals, have anti-acidification effect and reduce the incidence of myocardial infarction". The results show that a cup of black tea can even play a stronger anti-acidification role than garlic, broccoli, carrots and Chinese cabbage for specific free radicals. The drinking method of acid-resistant black tea is to drink 2 ~ 3 cups of black tea every day. Selenium, vitamins c, e, a, etc. They are all anti-acidification substances, and black tea will be more effective if eaten with foods rich in these substances. Drinking black tea with vegetables, fruits, butter, milk and eggs at the same time is called a healthy and reasonable eating habit. But at the same time, we should also pay attention to avoid eating too much calories and sugar. Black tea also has various antibacterial effects to prevent colds. Flavonoids in black tea have antibacterial effects such as killing poisonous bacteria in food and making influenza virus infectious. In addition to preventing colds, some people gargle with black tea when a cold causes a sore throat. 3. Black tea is most suitable for drinking in winter. People who drink green tea when they don't eat will feel sick to their stomachs. This is because tea polyphenols, an important substance contained in tea, have astringent taste and have a certain stimulating effect on the stomach, especially on an empty stomach. Black tea is fermented and baked, and tea polyphenols are enzymatically oxidized under the action of oxidase, so the content is reduced and the irritation to the stomach is also reduced. Black tea not only won't hurt the stomach, but also nourish it. Drinking black tea with sugar and milk often can diminish inflammation and protect gastric mucosa, and also has a certain therapeutic effect on ulcers. However, black tea is not suitable for cold drinking, which will affect the effect of warming the stomach, and may also reduce the nutritional content because it is left for too long.
