What are the advantages and disadvantages of drinking tea? Many people know that drinking tea is very beneficial to health. There are many kinds of tea, among which black tea and green tea are the most common, but tea is not suitable for everyone, and you can't drink too much at ordinary times. Let's learn more about the advantages and disadvantages of drinking tea.

What are the advantages and disadvantages of drinking tea 1 1. The advantages of moderate drinking tea

1. Relieve fatigue and refresh your mind. Most tea leaves contain caffeine, a refreshing substance. Proper intake of caffeine can stimulate the nerve center of the human body, thus eliminating fatigue and relieving fatigue.

2. Clear liver and improve eyesight. Tea contains tea polyphenols, which can be combined with some toxic substances in the human body and excreted through the diuretic effect of caffeine to prevent excessive accumulation of toxins in the human body and reduce the burden on the liver. In addition, there are many vitamins in tea, which can enhance the photosensitive ability of retina and prevent night blindness to some extent.

3. Fresh breath. Breathing and bad breath are embarrassing things in life. Many times, brushing your teeth and gargling can't solve the problem. At this time, you can choose to drink tea to relieve symptoms, because catechins in tea can kill oral bacteria, thus refreshing your breath to some extent.

Second, the disadvantages of drinking tea

1. leads to insomnia and kidney overload. Drinking a lot of tea a day or before going to bed is easy to consume too much caffeine, which makes people overexcited and causes insomnia. Moreover, for people with poor cardiovascular function and renal insufficiency, it is easy to increase the physical burden and cause symptoms such as excessive heartbeat.

2. Obstruct ulcer healing. If people suffer from gastrointestinal ulcers, it is best not to drink tea, because drinking tea will stimulate the secretion of gastrointestinal digestive juice, which is not conducive to ulcer healing.

3. It is easy to lead to iron deficiency anemia. Drinking tea for a long time will affect people's absorption of iron, and iron will affect the exertion of human hematopoietic function. Severe iron deficiency in human body can easily lead to iron deficiency anemia.

What are the advantages and disadvantages of drinking tea? 2. The health care function of tea.

On the one hand, tea can detoxify.

Tea is a traditional Chinese medicine. Yi Yan, a herbal medicine, recorded: "Shennong tasted a hundred herbs and encountered 72 poisons every day, so he solved them with tea." The "tea" here is the "tea" now.

"Food Guide Materia Medica" says: the clear gas of tea can relieve the gas of mountain haze, the poison of Jiang Yang dew fog, and the heat of five spices.

The previous generation of doctors also believed that tea can also remove the poison of wine and food and fry the greasy poison.

As we all know in life, if food poisoning, or overeating spicy things, leads to throat discomfort, or acne, or oral ulcers, people who are not serious often drink one or two cups of green tea, that is, take green tea to clear away heat and detoxify.

Second, tea can clear the leader.

Green tea mostly uses the tender buds of tea trees. Buds have the vitality of spring and the function of cleaning the upper diaphragm, which is most beneficial to leaders.

Gu Kuang wrote "Tea Fu" in the Tang Dynasty, saying: "Nourish the essence of rice and vegetables, attack their greasy meat, clear the summer, and wash away the night's sleep."

Compendium of Materia Medica says: The reason why tea can purge heat, clear heart and help digestion lies in its bitter, sweet and slightly cold taste. But also can help digestion, eliminate phlegm, heat, polydipsia and clear the brain.

If the leader is upset, dizzy, top-heavy, his eyes are blurred, watery, or his eyes are red due to the floating of virtual fire, he can drink several cups of green tea first.

In my clinical treatment of dizziness, I often choose to add green tea blindly in the syndrome differentiation prescription, which is to follow the trend.

Third, tea is a good drink and can compete with you.

Compendium of Materia Medica has an incisive comment on the health care function of tea, saying: "Tea is cold, contrary to warm brain fat, so eating it makes people thin, remove fat, double manpower, please people's aspirations, benefit people's minds, open people's ears, relieve people's limbs, solve people's troubles, and make people get carried away and sleepy." Talking about four or five mouths is really comparable to competing with you. "

This passage is wonderful, pointing out the health-preserving function of tea, and making people want to drink a cup or two of tea after reading it.

Yusheng Xia Zhishi, with three or two friends, sat down for tea. One cup to relieve summer heat, two cups to clear the heart and three cups to soothe the nerves. There is a faint fragrance in tea, which makes people relaxed, intoxicated and savored, as if the breeze slowly entered, and the restless heart naturally turned to calm.

Fourth, the medical analysis of tea.

Traditional Chinese medicine can cure diseases because it has four flavors. Each traditional Chinese medicine has different smells, different weights, different cold and heat, and different effects.

For example, qi is yang, strong qi is pure yang, and thin qi is yin in yang. When the gas is thin, it will be vented, while when the gas is thick, it will be hot. Taste is yin, strong taste is pure yin, and light taste is yang in yin. The taste is fine and smooth, but the taste is strong, which has a cathartic effect.

As far as tea is concerned, its qi is clear, which is the yin in the yang; Its taste is thin, and it belongs to yang in yin. Therefore, the efficacy of tea can not only be vented, but also passed on.

Fifth, don't drink too much tea.

Although tea is good, it should not be drunk excessively. Li Shizhen, a great doctor in the Ming Dynasty, pointed out from his personal experience in Compendium of Materia Medica: When he was young, he was greedy for drinking new tea, which led to "middle-aged people's stomach gas being slightly damaged, and drinking it would be harmful to avoid nausea and vomiting, that is, abdominal cold and diarrhea". Li Shizhen reminded the world: "Cold Xu Ruo, blood deficiency, long-term drinking will lead to cold spleen and stomach.

The vitality is dark, the soil does not make water, and the essence and blood lurk; Phlegm, swelling, flaccidity, yellow and thin, vomiting, acupoint diarrhea, abdominal pain, hernia and all kinds of internal injuries are also harmful to this tea. People's livelihood is used for daily use, and people who do it often do the same, while women suffer more, and customs are transferred to others, and they don't feel it. Less real tea, more miscellaneous tea, more harmful than words. People are addicted to tea, and they can't stop to take a sip from time to time. It is especially regrettable that they have been injured for a long time, and their blood is yellowish and weak, and they don't regret their illness. "

The tea that Li Shizhen longed for when he was young was green tea. Green tea is cold and its yin is very heavy. Long-term drinking will consume yang. If the body is yang-deficient, excessive drinking is the most harmful.

Li, a great doctor in Ming Dynasty, explained tea in his book "Analysis of the Medicinal Properties of Leigong Processing", which was similar to Li Shizhen's. He said: "The product of clearing profits makes the five internal organs salty. But overeating hurts the spleen, making people yellow and thin, and waking up the latter will also cut the spleen and ears. "

Tea is cold, and greed hurts yang, which is very harmful. Continued medical records contain one: "The king of Qin took three raw teas, and cold things accumulated into cold. The pulse is neither floating nor heavy. Internal and external pressing up and down is extremely powerful, firm but not soft, and fingers protrude from the skin. He can't return to a few people, nor can he return to the huge and powerful in both vertical and horizontal directions. This yin disease also hit the pulse. A popular fire is drawn from the chest and forced by the cold, so it is broad and powerful. " Fortunately, after his illness, Wang Haizang "cooperated with Zhenwu Decoction, Sini Decoction and Lizhongtang Pills to add Radix Paeoniae Alba and Fennel, and he was not arrogant. He took 100 pills every day and 80 pills every night until the liquid sweated."

From this analysis, the king of Qin was a man with yang deficiency, and he was greedy for cups and tea, which led to the stagnation of Yang Qi. So he gave him a prescription for warming yang and dispelling cold. Yang Can turns cloudy, haze turns to Yang, Yang turns to Yin, Yang turns to Yin, and sweating occurs.

As late as the Qing Dynasty, Ling Huan's "Herbal Harm" also thought that tea had a negative side, "it can cool the stomach and eliminate fat. Drinking tea after drinking, introducing bladder meridian and kidney meridian, can make people feel cold pain in waist and feet, suffer from hernia, edema and contracture ... yellow and emaciated, keep people awake and become a drinking disorder. "

Sixth, you should avoid drinking tea.

Tea is partial in nature, sweet and cold in taste, and has the disadvantage of hurting yang. If people with yang deficiency drink it, the more they drink, the colder they get; If people with Wang Yang constitution drink it, the more they drink, the more refreshing they feel.

Simply put, tea can enter the lungs, resolve phlegm and benefit water; Enter the heart, clear away heat and detoxify; Into the spleen, it can cleanse dirt and get tired, and it can detoxify. Furthermore, all diseases such as indigestion, unclear mind, stagnation of phlegm and saliva, unfavorable stool, and persistent thirst, such as bloody stool, hematemesis, maggot blood, bloody dysentery, and eye diseases caused by fire, belong to fever and can be taken effectively.

Tea is cold and cool, so it is suggested that hot clothes are more suitable. If you take cold clothes, it is easy to accumulate phlegm.

Besides, after drinking tea, you can not only eat, but also meditate. If you drink tea on an empty stomach, the cold will go straight into the kidney and reduce the fire, which is harmful to your health.

The above discussion of tea from both positive and negative aspects hopes to make readers know more clearly that tea is a kind of drink and tea is biased. As Chinese medicine, we should not only fully understand the efficacy of tea, but also drink it according to its sexual and taste efficacy. In a word, you should not drink too much tea, you need to know some knowledge of Chinese medicine and have a correct view of treatment of tea.

What are the advantages and disadvantages of drinking tea?

Do you know that different teas have different functions, adapting to different seasons and different people? How to find the cup that suits you best in life?

Efficacy and function of oolong tea

Oolong tea is the most energy-enhancing variety of all teas. This is mainly because oolong tea is semi-fermented, and more polyphenols in the finished oolong tea are converted into tea pigments, which have strong antioxidant, degreasing and blood pressure lowering effects. In Japan, the metabolic functions of various teas were tested. The results show that green tea can increase the metabolism of 4 calories per hour, while oolong tea's metabolism per hour is 9 times that of green tea.

Efficacy and function of green tea

Green tea has obvious antioxidant and anti-inflammatory effects. Green tea comes from tender tea buds and is completely unfermented tea. To a great extent, the freshness of fresh leaves and natural substances, such as vitamins, amino acids, catechins, tea polyphenols and other nutrients, are retained. Therefore, the antioxidant, anti-aging, anti-cancer, sterilization and anti-inflammatory effects of green tea are obviously higher than other teas.

Efficacy and function of Pu 'er tea

The soup is red and bright, soft in taste and less irritating to the stomach. In the fermentation process, substances or decomposition products are polymerized, and with the participation of many beneficial bacteria, various functional components are formed, which have obvious functions of promoting digestion, relieving boredom, promoting metabolism and accelerating fat decomposition.

Pu 'er raw tea can be said to be an enhanced antioxidant. Made from Yunnan big leaf sun-cured green tea, it largely retains a large number of natural functional substances in tea. It has a rich taste and distinct layers, and can be called an enhanced version of green tea, with remarkable refreshing and antioxidant effects.

Efficacy and function of yellow tea

Yellow tea belongs to mild antioxidant and anti-inflammatory tea. The production process of yellow tea is similar to that of green tea, and the effect is similar. However, compared with green tea, the production technology of yellow tea is slightly yellow, which promotes the oxidation of polyphenols, has a mellow taste and is less cold than green tea.

Efficacy and function of black tea

Black tea has the reputation of generating heat, warming the stomach and helping digestion. I believe many people have heard of the online hot word "black tea warms the stomach". This is mainly because black tea belongs to fully fermented tea, and a large amount of theaflavins, thearubigins and other components and a small amount of polyphenols are formed in tea, which determines the color, taste and fragrance of black tea. Among them, theaflavins are excellent in regulating blood lipid and lowering cholesterol, while thearubigins is a strong antioxidant, which, together with polyphenols, does little harm to the stomach and has the functions of promoting digestion and relaxing blood vessels.

Efficacy and function of black tea

The effects of black tea are obvious and many. Black tea belongs to post-fermented tea, with high degree of fermentation and rich in vitamins and minerals. With the participation of microorganisms, it can accelerate the transformation of tea polyphenols into tea pigments and other special substances beneficial to human body, especially for improving intestinal tract, reducing fat and weight, and reducing three highs.

Efficacy and function of white tea

White tea is known as medicinal tea, especially old white tea. It is often said that "tea lasts for one year, medicine lasts for three years, and treasure lasts for seven years". White tea is rich in amino acids, rich in enzyme activity, fresh and mellow in taste, and has the functions of clearing away heat and toxic materials and preventing colds. Old white tea, with the extension of aging years, its connotation transformation, antibacterial and anti-inflammatory, antiviral, free radical scavenging and other effects are more obvious, so it will be used as medicine in traditional Chinese medicine.

Taboo of drinking tea

Because different teas have different functions and adapt to different seasons and different people, drinking tea has both advantages and disadvantages, which requires us to know how to drink tea scientifically. The following are some points summarized by the author, hoping to help you drink tea better.

First, drink tea in moderation, not in excess, and don't drink strong tea, overnight tea or hot tea.

Second, women, children, the elderly and other people with gastrointestinal sensitivity can drink some Pu 'er cooked pu appropriately.

Third, the efficacy of most black teas on the market is often exaggerated. It is very unlikely to really drink good quality black tea. It is recommended not to drink black tea.

Fourth, women should pay attention to the five periods of menstruation, first pregnancy, third trimester, lactation and menopause, and try to drink less tea.

Fifth, people who are in poor health or have diseases such as stomach, spleen and heart. You should try to drink less herbal tea, especially when taking medicine.
