Tea is welcomed by people, not only because it is a popular good drink, but also because it can play a certain role in health care and treatment. As Su Shi, a poet in the Song Dynasty, said, "Di Wei doesn't have to take a pill in Lutong and use seven bowls of tea." Jin Lu is a scholar who loves tea. Su Shi thinks that drinking tea often is better than taking medicine. This is also the case. There are many records about drinking tea and keeping in good health in the historical materials when tea was opened. These records describe the utility of tea wonderfully, and even some ancient famous doctors have expounded it in their works. Modern biochemical and medical research has proved that the chemical composition of tea contains more than 450 organic compounds and no less than 15 inorganic mineral nutrients. It can be seen that tea has both nutritional value and pharmacological effect on human body, which is closely related to human health. Of course, although tea has health care and pharmacological effects on human body, it can't fully play the role of treatment and fitness because of its limited content, which should also be seen.

(a) the medicinal value of green tea:

Tea can stimulate the central nervous system and cheer up the spirit. Whenever people are sleepy, sleepy, listless and blocked at work, drinking a cup of tea can make people feel refreshed, fresh-minded and open-minded. There is a saying in the theory of food that "it is good to think after a long bitter tea". There is a saying that "tea tastes bitter, which makes people think well and lie down less." Tea also has the functions of digestion, diuresis, thirst quenching, disinfection and hangover relieving, and intelligence improvement and eyesight improvement. Discussion on detoxication, greasy intoxication and burning intoxication ... Drinking more and reducing fat can get rid of oil. Su Dongpo, a Wen Hao in Song Dynasty, loved tea. He said with deep experience: "One cannot live without tea for a day. "。

Rinse your mouth with tea after every meal, and your spleen and stomach will clean themselves up. People who have meat between their teeth will give up tea. Thirsty people, as long as they sip a few mouthfuls of tea, will feel that their tongues are sweet and their thirst will stop. Although jade liquid is nectar, it is hard to compare with it. As for the functions of relieving alcoholism, treating dysentery and disinfecting external sores. There are many records in < Materia Medica Tong Yuan.

(B) refresh thinking, improve work efficiency

In life, you may have such an experience: in the dead of winter, when you are sitting at your desk, dizzy and tired, soaking in a cup of strong tea will definitely make you refreshed and exhausted. The sun is scorching and the wind is cold. When you are running around for a long time, sweating and exhausted, drinking a pot of fragrant tea will make you feel refreshed and refreshed. This is the effect of tea to refresh, benefit thinking and eliminate fatigue. Therefore, some writers, poets and scientists generally need strong tea to help them write. Drivers who drive at night often have to drink a cup of strong tea before leaving, so as to concentrate and ensure driving safety.

People who work in the field for a long time often drink some strong tea, which also helps to prevent bacterial infection and protect their health.

Tea can refresh the mind and relieve fatigue. This is because the caffeine content in tea is relatively high, accounting for about 40% of the total amount of finished tea. After caffeine is absorbed by human body, it can not only stimulate the central nervous system, clear the mind and help thinking, but also accelerate blood circulation, activate bones and muscles and relieve fatigue. Clinically, it is effective in treating colds and headaches without side effects. At the same time, caffeine can also dilate blood vessels and relax coronary arteries, and can also be used as an auxiliary drug for the treatment of angina pectoris and myocardial infarction.

Caffeine in tea is also different from ordinary pure caffeine. Pure caffeine is irritating to the stomach, and caffeine in tea will be neutralized by other substances in tea soup to form a complex. Experiments show that drinking tea will not cause the increase of gastric acid and gastrointestinal fluid, but can play the role of "harmonizing the stomach".

(3) Quench thirst, promote fluid production, promote digestion and eliminate annoyance.

If you can drink a cup of green tea in the hot summer, you will feel drooling and cool all over. This is because the chemical components in tea soup (such as polyphenols, sugars, pectin, amino acids, etc.) react with saliva in the mouth, which makes the mouth moist and produces a cool feeling. In addition, caffeine controls the body temperature center from the inside, regulates the body temperature, stimulates the kidneys and promotes excretion, so that a large amount of heat and dirt in the body can be eliminated and metabolized to achieve a new physiological balance.

Tea contains iodine and fluorine, iodine has the function of preventing and treating hyperthyroidism, and fluorine is the component of human bones, teeth, hair and nails. And in our diet, the content of fluorine is also very low. Drinking more tea in this way will supplement the deficiency of body nutrition, especially improve the acid resistance of teeth.

Tea is also an oral hygiene agent. After getting up every day, I often feel thirsty and bitter. At this time, if you can drink a cup of green tea, you can remove the mucus in your mouth, eliminate bad breath and stimulate your appetite. There is a proverb in our country: "A cup of tea in the morning will starve the drug seller to death." It shows that drinking morning tea is good for physical and mental health. It makes sense that some places in the south still have the habit of drinking morning tea.

In life, people often need to drink several cups of strong tea after a big meal, which can prevent greasy accumulation. This is because caffeine can excite the central nervous system, promote the secretion of gastric juice and the digestion of food, and promote the digestion of fat.

In addition, the aromatic substances in tea also have the functions of dissolving the fat in bath, helping digestion and eliminating the fishy smell in mouth. The aromatic substances can also give people a feeling of excitement and pleasure, increase the secretion of gastric juice and promote the consumption of protein and fat.

(4) sterilization, anti-inflammation, diuresis and detoxification

Polyphenols in tea can solidify and precipitate protein. Tea polyphenols combined with unicellular bacteria can coagulate protein and kill bacteria. Such as cholera, typhoid fever and Escherichia coli, are seriously harmful. Most of them will lose their vitality if they are soaked in strong tea for a few minutes. Therefore, people in China often use strong tea to treat bacillary dysentery, or apply it to the wound to relieve inflammation and detoxify and promote wound healing. At present, Chinese patent medicines made of tea for treating dysentery and colds are also effective.

As the saying goes, drinking is often "the beginning of ceremony and the end of chaos", while drinking tea in person can be "the beginning of ceremony and the end of ceremony". Tea can also sober up and quit smoking. When people drink too much, because alcohol poisons the nervous system, people will feel weak, even sick and vomiting, and lose their minds. At this time, if you drink several cups of strong tea, you will use polyphenols and caffeine in tea to neutralize alcohol, so that the toxic substances of alcohol can be excreted in time through urine, thus detoxifying and sobering up.

Nicotine in tobacco is a toxic alkaloid. People smoke continuously, and nicotine enters the human body with the smoke. When the content reaches a certain level, poisoning phenomena occur: dizziness, brain swelling and general malaise. At this time, if you drink strong tea, you can rely on the anti-production effect of tea caffeine to get rid of it. In life, some people often drink tea while smoking, which is not easy to cause poisoning. In recent years, some people have done experiments and tea has the effect of quitting smoking. At present, the smoking cessation tea and candy on the market are all made of tea as the main raw material and through special processes.

(5) Supplementing nutrition and enhancing physical fitness.

According to modern chemical analysis, tea contains many vitamins, mainly vitamin A, vitamin b 1, vitamin b2, nicotinic acid, pantothenic acid, vitamin C and so on.

These trace vitamins are indispensable nutrients for human body. For example, vitamin C is not only a substance that the human body can't synthesize naturally, but also a necessary component to generate connective tissue. It can maintain the normal physiological functions of teeth, bones, blood vessels and muscles and promote wound healing. If the human body lacks vitamin C, it will suffer from scurvy, or gum bleeding, capillary fragility, subcutaneous bleeding and so on. According to relevant historical records, drinking tea is enough to prevent diseases caused by insufficient or cut-off vitamin C food supply in wars and navigation. In tea, green tea contains more vitamins. Every 100g of fresh tea contains about 180mg of vitamins, which is equivalent to lemon and spinach.

Vitamin D and vitamin C have an important synergistic effect, which can help the body absorb vitamin C and reduce the occurrence of cerebral hemorrhage. Tea polyphenols in tea polyphenols also have the function of vitamin D, which can enhance the elasticity of blood vessels and the permeability of blood vessel walls, and prevent arteriosclerosis and stroke. Pantothenic acid has the effect of moistening skin. There is more vitamin K (chlorophyll) in black tea, which can be compared with fish and spinach. If you drink five cups of black tea every day, you can completely meet the human body's demand for vitamin K. Therefore, drinking tea regularly can provide a variety of vitamins for the human body to a certain extent, which is conducive to fitness and disease prevention.

In addition, tea contains a variety of minerals, especially trace elements that are rare in other foods, such as copper, fluorine, magnesium, molybdenum and aluminum. At this time, the human body has certain nutritional value and pharmacological effects. Although the content of copper and iron is not much, it has a certain effect on preventing and treating anemia because of its blood-generating function.

(6) lose weight, keep fit, strengthen the heart and prevent diseases.

With the development of modern science and technology, people have a deeper understanding of drinking tea. Besides what I said before, many subtle functions have been discovered.

For example, Yunnan Pu 'er tea has always been famous for its remarkable efficacy. The ancients also spoke highly of it. According to reports, French medical research has proved that Tuocha in Pu 'er tea has the functions of losing weight, bodybuilding, anti-lipid and preventing cardiovascular diseases. Clinical trials have also proved that people who often drink Tuocha at the age of 40-50 have obvious weight loss effect, and also have different effects on people of other age groups. More than 70% cases significantly reduced the triglyceride content in human body. Some people drink three cups of Tuocha every day for one month, and their blood lipid content drops by 30%. About half of the cases, the cholesterol content in the body has decreased. Therefore, Tuocha can relieve the worries of obese people and has a certain effect on patients with hypertension and cardiovascular diseases. At present, many scholars are conducting more extensive research.

According to research, oolong tea also has a certain weight loss and bodybuilding effect. Oolong tea enjoys a high reputation in Japan. A few years ago, there was an oolong tea craze in Japan, especially for young women and middle-aged obese women, who regarded oolong tea as a "slimming tea" and a "panacea for beauty and health". In fact, oolong tea does have a strong role in decomposing fat. Regular drinking can help digestion and diuresis, and it also has certain effect on treating constipation.

Tea also has a special purpose, which can prevent the harm of some radioactive substances to human body. According to the investigation after World War II, in the atomic bombing of Hiroshima, Japan, people who have long-term tea drinking habits suffered less radiation damage and had a higher survival rate.

At present, some units in China have made tea into radioprotective drugs, which have a certain effect on treating radiation injury, protecting blood picture and increasing white blood cell count. In the research department of radioactive substances, tea is also listed as labor insurance products, and everyone must drink it.

In recent years, some places are conducting research on the prevention and treatment of cancer with tea. Studies have shown that a substance in tea can inhibit cancer cells in the human body through blood circulation and play a preventive role. This needs further study.

Although tea has all the above functions, it will also affect your health if you drink it improperly or drink too much strong tea. We must attach great importance to this point, otherwise it will be counterproductive.

(7) Drinking tea "four taboos" is good for health.

Tea is very particular. This is because drinking tea has advantages and disadvantages, and the gains and losses depend on whether it is reasonable or not. Tea must be ready at once. In the long history of China people drinking tea for thousands of years, a set of scientific tea drinking methods has been summarized. The so-called reasonable drinking tea is to give full play to the beneficial effects of drinking tea on the human body and avoid its disadvantages. Drinking tea varies with mental and physical labor, physical strength, working conditions and tea. Drinking tea should not only meet the needs of the body, but also study the brewing method.

Now drink it. Since ancient times, people have been used to using teapot cups, first brewing in the teapot and then pouring them into the cups for drinking. The ancients called it tea. Nowadays, many people are used to drinking tea directly from cups, whether for themselves or for guests, which is very unreasonable. Familiar guests can sit and chat for a while, and they can drink more: if they are unfamiliar, they will waste tea by taking a sip or not. Second, the chemical composition has changed, and trace elements have been leached, which not only worsens the color and flavor, but also accumulates unhealthy substances (such as zinc, copper, chromium, welfare, etc. ) exceeding the hygienic standard is harmful to people's health. At present, there is a saying in society that drinking overnight tea will cause cancer, which is unfounded. Although some people can say a thing or two, it is difficult to draw a conclusion. Nevertheless, it is better not to drink overnight tea. This is because, when the temperature is suitable, especially in summer, due to the role of vitamins, tea soup has changed color, even turned sour and turned dark brown. From a health point of view, such tea is not hygienic enough.

Drink tea in moderation. It is beyond reproach that drinking tea is good for health. But there is always a limit to everything. Without the limit of degree, things tend to develop in the opposite direction. The same is true for drinking tea.

Drinking tea is good for health, not to say that the more tea you drink, the better. Traditional Chinese medicine research has proved that according to different constitutions, people with weak spleen and stomach should not drink tea, while those with strong spleen and stomach should drink tea.

This is because drinking tea can stimulate the central nervous system. Tea contains caffeine. If it accumulates too much in the human body and exceeds the hygienic standard, it will be poisoned and damage the nervous system.

This is why drinking tea is easy to lose sleep. In severe cases, it will also lead to mental decline and reduced thinking ability. Generally speaking, it is better for each person to use 5 ~ 10g of tea every day and soak it for three times, which can be increased in summer. At the same time, tea must not be used before or after taking the medicine.

Try to drink less tea.

Drink tea at the right time. One of the functions of tea is to help digestion. Drinking tea on an empty stomach and before meals is not suitable, which will dilute gastric acid and hinder digestion. It is best to drink tea 20 minutes after meals. Because, 20 minutes after a meal, when gastric acid digestion food is not perfect, drinking tea not only helps digestion, but also stimulates gastric acid to continue to secrete and digest. In this way, drinking tea can help digestion Tea also has the function of relieving fatigue, especially in fatigue, which can restore people's thinking ability and promote blood circulation. In this way, people should not drink tea before going to bed, especially strong tea, otherwise it will cause insomnia. Because within four or five hours of drinking strong tea, tea will still have an effect on the human body.

(7) Other purposes

Tea is mainly used as a beverage, which is a kind of beverage with good color, fragrance and taste. But in addition to its shortcomings, there are many special uses, which can also be said to have practical value in daily life.

Tea has existed in people's lives for thousands of years. Over time, it will naturally find many special uses. These uses are combined, and there are about 20 kinds, which are introduced as follows:

1, boiled tea eggs are a delicious food, some are cooked with soaked tea leaves, and some are cooked with tea leaves. But it is best to use black tea. Because ordinary black tea is cheap, the boiled tea eggs are ruddy in color and delicious. The key point of boiling tea eggs is to cook the eggs first, break the eggshell gently, and then put the tea leaves in water to continue cooking, which can make the tea leaves taste better.

2. Don't throw away the used tea, spread it on a wooden board and dry it for thousands of years. Over time, it can be used as a pillow core. It is said that tea pillows can refresh your mind and improve your thinking ability. It makes sense to say that tea is cool.

3. Dry the used tea leaves and light them at dusk in summer, which can repel mosquitoes and is absolutely harmless to human body, just like mosquito-repellent incense.

4. Tea is rich in pigments, especially the reddish-brown pigment of black tea, which is widely used. It can be used to mix wine and make food. If the kitchen prepares a little black tea juice for the adjustment of dishes, it is much better than ordinary chemical pigments. Housewives who often drink tea at home might as well have a try.

5. The brewed tea leaves still contain inorganic salts, carbohydrates and other nutrients, which are buried in flower beds or flowerpots, contributing to the development and reproduction of flowers and plants. Friends who like potted plants generally know this purpose, which is much more convenient than garbage disposal.

6. With the development of food industry, tea has a special use. After the advent of black tea and toffee, it is already a delicious candy with unique flavor and fragrant smell. However, this is a professional use, which ordinary families can't do, but it can also show that tea is widely used.

7. Tea contains a lot of tannic acid. Tannic acid has a strong bactericidal effect, especially on filamentous bacteria that kill beriberi. Therefore, people with beriberi should boil tea into thick juice to wash their feet every night. It will heal after a long time without medication. But if you cook tea and wash your feet, you must persevere, and there will be no significant effect in a short time. And it is best to use green tea, and the content of tannic acid in fermented black tea is much less.

8. People with bad breath will be disgusted when talking to others. Tea has a strong astringent effect, and often putting tea in your mouth can eliminate bad breath. Gargling with strong tea has the same effect. If you don't drink tea well, you can put the tea in your mouth after soaking, which can reduce the bitterness, but the effect is the same.

9. Tea can remove dirt and grease. Therefore, after washing your hair, washing your hair with tea can make your hair black, supple and shiny. Generally, after using it several times, women will feel much better than shampoo and other things, because tea contains no chemicals and will not harm hair and skin.

10. Silk clothes are most afraid of chemical cleaners. If you wash silk clothes with soaked tea leaves and boiled water, you can keep the original color and the color is as bright as new. Washing clothes with nylon fiber may have the same effect.

1 1, throat inflammation, hoarseness, maybe a slight cold, but before going to see a doctor, I feel refreshed and feel less painful immediately after drinking several glasses of rock sugar, so maybe I don't need to see a doctor again. In the past, it was regarded as a folk prescription in rural areas. Today, medicine is developed and there are many drugs. If it really doesn't work, of course you have to see a doctor.

12, Zhang Zhongjing, a famous doctor in the later Han Dynasty in China, once said that "tea is effective in treating fecal pus". The so-called "fecal pus" is commonly known as dysentery. Modern medical scientists have also tested that tannic acid contained in green tea can kill germs. Drinking strong tea for three days in a row can relieve dysentery and cure it in five days. The medical function of tea is not limited to this. As mentioned above, if it is ineffective, you must see a doctor.

13, after eating green onions and garlic, go out to participate in the exchange immediately. The taste of garlic will make people worry. You might as well put a pinch of tea in your mouth, and after three or five minutes, the smell of garlic will disappear without a trace.

14, tea has anti-inflammatory, bactericidal and analgesic effects. If the child accidentally falls, scratches his skin, or has a red and swollen place, immediately rinse it with Leng Cha, and then chew some tea and apply it to the wound, which can relieve the pain and avoid bacterial infection. If the situation is serious, see a doctor again. Tea can play an emergency role.

15. If you are a friend who often writes or a student who studies, you can wash your eyes with half a cup of light tea in the eye washer when your eyes are tired, astringent or even hard to open, which can eliminate fatigue and make your blurred eyes shine, and you can get the same effect without eye drops. Especially for friends who drink tea, it is really a convenient and quick way.

16, washing sores, ulcers and blood pus with tea juice is a long-standing folk prescription in ancient rural areas. It can replace alcohol for disinfection and sterilization, and has the softness of boric acid water. You can also detoxify, take pesticides by mistake, and fill a lot of strong tea, which is equivalent to gastric lavage, but there will be no pain of gastric lavage with drugs.

17. Drinking the remaining tea and wiping the mirror or glassware can make the polished glassware shiny, but you must pay attention to dry the water, otherwise it will be more troublesome to make tea, and the stains left by tea will not be easily erased.

18, if someone drinks too much and drinks a few cups of strong tea, they will soon wake up. Theophylline can dissolve alcohol and contains a small amount of caffeine, which is a nerve center stimulant. Drinking with tea will never hurt the spleen and stomach, nor will it make drunken people vomit a lot and cause nausea.

19, people with beriberi often wear smelly shoes. Using toilet paper to wrap a thin layer of tea in shoes as insoles can not only eliminate odor, but also prevent it.

20. Newly bought wooden furniture, such as tables, chairs and cabinets, has a pungent smell of paint. If you wash it thoroughly with tea, the smell of paint will naturally fade, and it will disappear after several washes, which is much better than soap-free cleaner.

2 1, using the tea left over, wiping straw mats and tatami can eliminate the smell of sweat and dust and make it smooth as a mirror, especially in summer. After a period of time, rushing with tea will definitely make people feel refreshed, and lying on it will definitely make them fall asleep leisurely.

22. One of the most special uses of tea is as one of betrothal gifts. In the previous custom, the man must have tea when he is hired, and the woman who is hired is called "receiving tea". The reason is that "tea trees must be planted, but transplanting will not be born." Including the dual significance of being loyal to one's own life and having a son.

23. Bathing with tea leaves can not only remove body odor and dirt, but also maintain the skin. Bathing with tea can reduce the occurrence of skin diseases and make the skin shiny, smooth, soft and fat-free. In ancient rural society, after the baby was born, it was to take a bath with tea to play the above functions. Modernity is also worth advocating, because it is a bathing method with many benefits and no harm.
