First, the anti-aging effect of Tieguanyin
Some scientific studies at home and abroad show that human aging is related to the over-oxidation of unsaturated fatty acids in the body, and the over-oxidation of unsaturated fatty acids is related to the action of free radicals. Free radicals with high chemical activity can over-oxidize unsaturated fatty acids, make cell function mutate or decline, cause tissue proliferation and necrosis, and produce fatal diseases. Lipid over-oxidation is the devil of human health, but the culprit is free radicals. As long as the free radicals are removed, cells can get normal growth and development and live a long and healthy life.
Usually, the commonly used antioxidants are vitamin C and vitamin E, which can effectively prevent the over-oxidation of unsaturated fatty acids. Japanese researchers have shown that tea polyphenols, a polyphenol compound in Tieguanyin, have strong antioxidant and physiological activity, and are scavengers of human free radicals. According to the research of relevant departments, the efficiency of 1 mg tea polyphenols in scavenging excessive free radicals harmful to human body is equivalent to 9 micrograms of superoxide dismutase (SOD), which is much higher than other similar substances. Tea polyphenols can block lipid peroxidation and scavenge active enzymes. According to the results of Ota Tomoyo test in Japan, it is confirmed that the anti-aging effect of tea polyphenols is stronger than that of vitamin E 18 times.
Second, the anti-cancer effect of Tieguanyin
Cancer is an "incurable disease" that seriously threatens people's health today. Therefore, the study of tea anti-cancer has aroused great interest and concern. A few years ago, there was a report that the esophageal cancer of Shanghai residents decreased year by year because of drinking tea, so the fact that drinking tea can prevent cancer caused great repercussions all over the world. Nowadays, it has been recognized by the world that drinking tea can prevent and fight cancer, and Tieguanyin has the best anti-cancer effect in tea.
As early as 1983, Professor Takuo Okuda of Okayama University in Japan had screened dozens of plant polyphenols for their anticancer effects.
The results show that catechin (EGCG) has strong anticancer activity. Other scientists believe that Tieguanyin tea polyphenols are the main active components in the study of confirming Tieguanyin's anti-mutation. In the study of chemical carcinogenesis, the preventive effect of Tieguanyin tea polyphenols was affirmed. In addition, vitamin C and vitamin E in Tieguanyin can block the synthesis of nitrosamines, a carcinogen, which plays a great role in the prevention and treatment of cancer.
Third, the anti-arteriosclerosis effect of Tieguanyin
Tea polyphenols play an important role in human fat metabolism. The human body has high cholesterol, triglyceride and other cardiovascular diseases, such as fat deposition on the inner wall of blood vessels and atherosclerotic plaques after vascular smooth muscle cells proliferate. Tea polyphenols, especially catechins ECG and EGC in tea polyphenols and their oxidation products theaflavins, are helpful to inhibit this mottled proliferation, reduce fibrinogen which forms enhanced blood coagulation viscosity, and make blood coagulation clear, thus inhibiting atherosclerosis.
1may 3, 9991day, at the fourth symposium on oolong tea and health held in Tokyo, Japan, Vice President Chen Ling of Fujian Institute of Traditional Chinese Medicine reported that they had taken 25 patients with hyperlipidemia and obesity as clinical observation objects to explore the effect of drinking oolong tea Tieguanyin on inhibiting the oxidation of low-density lipoprotein in blood and improving blood lipid metabolism. Studies have proved that tea polyphenols and vitamins in Tieguanyin can inhibit the oxidation of low-density lipoprotein in blood. Dr. Masahiko Hara of Mitsui Institute of Agriculture and Forestry in Japan has also confirmed in many years' research that tea polyphenols can not only reduce cholesterol in blood, but also significantly improve the ratio of high-density lipoprotein to low-density lipoprotein in blood. Caffeine can relax blood vessels, speed up breathing, reduce blood lipids, and has a certain effect on the prevention and treatment of cardiovascular and cerebrovascular diseases such as coronary heart disease, hypertension and arteriosclerosis.
According to the investigation of 1080 farmers in Anxi Tea Township, Fujian Province in 1974, the incidence of not drinking Tieguanyin tea was 3.1%. Occasionally drinking is 2.3%; Drinking all the year round (more than 3 years) is 1.4%. It can be seen that people who often drink Tieguanyin have a lower incidence of coronary heart disease than those who do not drink Tieguanyin.
Fourth, the role of Tieguanyin in preventing and treating diabetes
Diabetes is a worldwide disease. About 200 million people in the world suffer from diabetes, and more than 30 million people in China suffer from diabetes. Diabetes mellitus is a chronic progressive disease with disorder of glucose metabolism. The typical clinical manifestations are "three more and one less", that is, drinking more, urinating more, eating more and wasting away, and being weak all over. This disease is called "diabetes" in Chinese medicine, which belongs to the category of scorching damp heat. The main reason for getting sick is the lack of polyphenols in the body, such as vitamin B 1, pantothenic acid, phosphoric acid, methyl salicylate, etc., which makes the sugar metabolism disorder, the blood sugar in the body increases sharply, and the metabolic effect is weakened.
The clinical experiments of Japanese medical doctor Ogawa Takechiro and others have confirmed that drinking tea regularly can supplement vitamin B 1, pantothenic acid, phosphoric acid, methyl salicylate and polyphenols in human body in time, and can prevent the occurrence of diabetes. For patients with moderate and mild diabetes, blood sugar and urine sugar can be reduced to very little or completely normal; For patients with severe diabetes, it can reduce blood sugar and urine sugar and relieve various main symptoms.
Five, Tieguanyin's slimming and bodybuilding function
Obesity is a nutritional disorder accompanied by the continuous improvement of people's living standards, which is caused by excessive nutrient intake or insufficient use of energy stored in the body. Obesity not only brings a lot of inconvenience to people's daily life, but also causes cardiovascular diseases and diabetes.
1996, Fujian Institute of Traditional Chinese Medicine conducted a study on the slimming effect of drinking Tieguanyin on 102 adult men and women with simple obesity. The research shows that Tieguanyin contains a lot of tea polyphenols, which can not only improve the function of lipolytic enzyme, but also promote the metabolic activity of neutral lipase in tissues. Therefore, drinking Tieguanyin can improve the body shape of obese people, effectively reduce the subcutaneous fat and waist circumference of obese people, and thus reduce their weight.
People's Hospital of Quanzhou City, Fujian Province used Tieguanyin slimming tea to treat 164 people suffering from obesity, taking slimming tea12 ~14g every day, 15 days as a course of treatment. After two courses of observation, the patients' blood lipid, triglyceride and cholesterol have obviously decreased, and their weight has also decreased, and the total effective rate of treatment has reached over 70%.
Sixth, the role of Tieguanyin in preventing and treating dental caries
It is generally believed that there are two major diseases that harm people's teeth, one is dental caries and the other is periodontitis. Dental caries, commonly known as tooth decay, is a common and frequently-occurring disease in dentistry. There are many reasons for dental caries, one of which is that the teeth are poorly calcified, the texture is not hard enough, and they are easily damaged. Drinking tea can protect teeth, which has been used for a long time in ancient China. Su Dongpo in Song Dynasty said in Tea Theory: "gargling with strong tea can not only get rid of boredom, but also strengthen teeth and eliminate smoking." According to modern scientific analysis, Tieguanyin is rich in fluorine, but the fluorine content in general food is very small. About 40% ~ 80% of fluoride in Tieguanyin is dissolved in boiled water, which is easily combined with calcium in teeth to form a layer of calcium fluoride on the surface of teeth, which plays a role in preventing acid and caries.
In Japan, a survey was conducted on the dental caries rate of school children in two neighboring villages. The results show that drinking Tieguanyin has a good effect on preventing and treating dental caries. Every school child drinks a cup of Tieguanyin every day, and if the fluorine content is 0.4 mg, it will last for one year, and half of the children suffering from dental caries will be cured. Japan counted 100 primary school students suffering from dental caries. After drinking Tieguanyin, 55% of them suffered from dental caries. It can be seen that drinking Tieguanyin has a preventive effect on people who have no dental caries and a therapeutic effect on people who have dental caries.
Seven, tieguanyin sterilization stop dysentery.
Tieguanyin has long been used to treat dysentery and stomachache in Anxi. There are also many records in ancient Chinese medical books about the use of tea to treat bacillary dysentery, dysentery, dysentery, acute enteritis and acute gastritis. Why can Tieguanyin play a role in sterilizing and stopping dysentery? Mainly tea polyphenols compounds. Because tea polyphenols enter the gastrointestinal tract, it can relax the tension function of the intestine and ease the intestinal movement; At the same time, it can coagulate the intestinal protein, because the bacteria itself is composed of protein. When tea polyphenols meet with bacteria protein, the bacteria will die immediately, which plays a role in protecting the gastrointestinal mucosa, so it has the effect of treating enteritis.
Eight, Tieguanyin's function of clearing heat and reducing fire
Tea is a good drink for heatstroke prevention and cooling. Li Shizhen's Compendium of Materia Medica states: "Tea is bitter and cold, and ……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………… ..... Warm drinks will cause the fire to drop due to cold, while hot drinks will rise and disperse by internal heat. " In the dog days of midsummer, when the sky is cool and the summer heat is pressing, drinking a cup of cool Tieguanyin or a cup of hot Tieguanyin will make you feel cool physically and mentally and produce fluid to relieve the summer heat. This is because tea soup contains tea polyphenols, sugars, amino acids, pectin, vitamins, etc., which react chemically with saliva in the mouth and moisten the mouth, so it can play the role of promoting fluid production and quenching thirst. At the same time, due to the caffeine in Tieguanyin, a lot of energy is released from the pores of human skin. It is reported that drinking a cup of hot tea, sweating through human skin pores, is equivalent to 50 times of this cup of tea, so it can make people feel cool and relieve summer heat.
Nine, Tieguanyin's refreshing and thinking-benefiting function
It is almost known that drinking tea can refresh your mind. There are a lot of medical books in China in the past dynasties, and all the literati and monks in the past dynasties waved their wonderful pens to praise the refreshing and thinking-benefiting power of tea. Bai Juyi's poem "Give Thirteen Kings to the East" says: "Join hands with the moon by the pool, and open the bamboo to the wind. Drive away the sorrow and know the strength of wine, and break the sleep to see the tea. " The poem clearly mentions the power of tea to refresh and break sleep. Su Dongpo's poem said, "build 30 pieces of tea, regardless of the taste, and give them to Bao Jushi, the monk fighting the sandman." He said that he would give the tea to Bao Jushi so that he could drink it and avoid dozing off during meditation. Drinking tea can benefit thinking, so it is loved by people, especially by some writers, poets and other mental workers. For example, Balzac, a great French writer, Han Suyin, a Chinese-American woman writer, and Yao Xueyin, a famous Chinese writer, all love drinking tea to help their writing.
Tieguanyin can refresh the mind, and its function mainly lies in caffeine in tea. Caffeine has the functions of exciting the central nervous system, improving thinking and improving efficiency. Therefore, after drinking tea, you can break sleep, refresh yourself, relieve boredom, clear your head and improve your thinking, which can significantly improve your oral defense ability and the response of mathematical thinking. At the same time, Tieguanyin contains polyphenols and other compounds, which counteracts the adverse effects of pure caffeine on human body. This is also one of the important reasons for the long history, enduring prosperity and continuous development of tea drinking.
Ten, Tieguanyin sobering up the enemy smoke.
It is also a well-known fact that tea can sober up and fight against cigarettes. Wang Yangming, a philosopher in the Ming Dynasty, famously said, "Just as you are drunk, you need tea to sober up", which shows that our people have long recognized the efficacy of drinking tea to relieve alcoholism. The ancients often "drown their sorrows with wine" and "sober up with tea". Liu Yuxi, a poet in the Tang Dynasty, was drunk one day and remembered that Bai Juyi had "six classes of tea" to sober up, so he sent someone to give something for tea to sober up, which was passed down as a tea story by later generations. The main component of wine is alcohol, and a glass of wine contains10% ~ 70% alcohol. Tieguanyin tea polyphenols and ethanol (the main ingredient in wine) can cancel each other out, so drinking tea can relieve alcohol.
Tieguanyin can not only sober up, but also fight against cigarettes. Because Tieguanyin contains a phenolic acid substance, it can precipitate nicotine in tobacco and excrete it. At the same time, caffeine in Tieguanyin can improve the liver's ability to metabolize drugs, promote blood circulation, excrete nicotine in human blood from urine, and alleviate and eliminate the side effects caused by nicotine. Of course, this effect is not only the single effect of caffeine, but also the result of cooperation with tea polyphenols, vitamin C and other components.
