Can I ask you about Tieguanyin?
Tieguanyin originates from Xiping Township, Anxi County, and has a history of more than 200 years. Regarding the origin of the Tieguanyin variety, there are still two historical legends left in Anxi. One is that Wei Yin, a tea farmer in Xiping, made a tea. Dream, a tea tree given by Guanyin Bodhisattva, was dug and planted; another story is that a man named Wang Shirang from Yaoyang, Anxi picked leaves from a tea tree and made tea for the emperor. The emperor named it "Iron Tea". Guanyin".
The harvesting technology of Tieguanyin tea is special. It does not pick very young buds and leaves, but 2-3 leaves of mature shoots. It is commonly known as "open-face picking", which means that the leaves have been fully expanded. Pick when buds form. The fresh leaves collected should be fresh and complete, and then cooled, sun-dried and shaken (made green) until the natural floral fragrance is released. When the aroma is strong, stir-fried, rolled and wrapped (rolled with cotton cloth to make tea), to make the leaves more fresh and whole. The tea leaves are rolled into particles and then dried over a slow fire. After the raw tea is made, it is then screened, winnowed, sorted, evenly stacked, and packaged to make commercial tea.
Tieguanyin is the best oolong tea. Its quality characteristics are: tea sticks are curled, fat and round, heavy and even, sandy green in color, and the overall shape is like a clear dragon head, a spiral body, and a frog's legs. After brewing, the soup is golden and rich like amber, with a natural and fragrant orchid fragrance. The taste is mellow and sweet, with a long aftertaste. It is commonly known as "yinyun". Tieguanyin tea has a high and long-lasting fragrance, which can be said to be "the fragrance remains after seven brews".
To drink Tieguanyin tea, small and delicate tea sets are necessary. Small teapots and teacups are preferred. Put the tea leaves into the teapot until it is five minutes full. After brewing with boiling water and washing the tea, add more water and brew for 2-3 minutes. Pour it into a small cup and drink. You can continue to add water for brewing in the future. When drinking Tieguanyin, you should first smell its fragrance and then taste its taste. Although the amount you drink each time is not much, it is full of fragrance and endless aftertaste.
The role of Tieguanyin
The anti-aging effect of Tieguanyin Some scientific research at home and abroad have shown that human aging is related to the excessive oxidation of unsaturated fatty acids in the body. Excessive oxidation is related to the action of free radicals. Free radicals with high chemical activity can over-oxidize unsaturated fatty acids, cause cell function mutation or decline, cause tissue proliferation and necrosis, and lead to fatal diseases. Excessive oxidation of lipids is the devil of human health, but the culprit is free radicals. As long as the free radicals are removed, cells can achieve normal growth and development and live a long and healthy life. Usually, commonly used antioxidants include vitamin C and vitamin E, which can effectively prevent the excessive oxidation of unsaturated fatty acids. Recently, Japanese researchers have shown that the polyphenols in Tieguanyin can prevent excessive oxidation; purine alkaloids can indirectly scavenge free radicals, thereby delaying aging.
2 The anti-cancer effect of Tieguanyin Cancer is an “incurable disease” that seriously threatens people’s health today. Therefore, research on the anti-cancer effects of tea has aroused great interest and concern in recent years. A few years ago, there was a report that Shanghai residents had reduced esophageal cancer year by year because of drinking tea. The fact that drinking tea can prevent the occurrence of cancer caused great repercussions around the world. Nowadays, it has been recognized by the world that drinking tea can prevent and fight cancer. Among the teas, Tieguanyin has the best anti-cancer and anti-cancer effects. As early as 1983, Professor Takuo Okuda of Okayama University in Japan screened dozens of plant polyphenolic compounds for their anti-carcinogenic effects. The results proved that catechin (EGCG) has strong anti-carcinogenic activity. In studies that confirmed Tieguanyin's resistance to mutation, other scientists believed that Tieguanyin tea polyphenols were the main active ingredient in this effect; in studies on chemical carcinogenesis, they affirmed the role of Tieguanyin tea polyphenols in preventing carcinogenesis. In addition, the vitamin C and vitamin E in Tieguanyin can block the synthesis of carcinogens-nitrosamines and play a great role in preventing and treating cancer.
The anti-arteriosclerosis effect of Three Iron Guanyin On May 31, 1999, at the Fourth Oolong Tea and Health Seminar held in Tokyo, Japan, Vice President Chen Ling of the Fujian Academy of Traditional Chinese Medicine reported They used 25 obese people with hyperlipidemia as clinical observations to explore the effect of drinking Oolong tea Tieguanyin on inhibiting the oxidation of low-density lipoproteins in the blood and improving blood lipid metabolism. Research has proven that the tea polyphenols and vitamins in Tieguanyin can inhibit the oxidation of low-density lipoprotein in the blood. Dr. Masahiko Hara of Japan's Mitsui Agriculture and Forestry Research Institute has also confirmed in years of research that tea polyphenols can not only reduce blood cholesterol, but also significantly improve the ratio of high-density lipoprotein to low-density lipoprotein in the blood. Caffeine can relax blood vessels, speed up breathing, lower blood lipids, and has a certain effect on preventing and treating cardiovascular and cerebrovascular diseases such as coronary heart disease, hypertension, and arteriosclerosis. According to a 1974 survey of 1,080 farmers in Anxi Tea Township, Fujian by the Coronary Heart Disease Prevention and Control Research Group of Fujian Medical University, they found that the incidence rate of those who did not drink Tieguanyin tea was 3.1%; those who drank it occasionally was 2.3%; those who drank it 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.
4. The role of Tieguanyin in preventing and treating diabetes. Diabetes is a worldwide disease. Currently, about 200 million people worldwide suffer from diabetes, and more than 30 million people in China suffer from diabetes. Diabetes is a systemic chronic progressive disease mainly characterized by glucose metabolism disorders. The typical clinical manifestations are "three more and one less", that is, polydipsia, polyuria, polyphagia, weight loss, and general weakness. This disease is called "diabetes syndrome" in traditional Chinese medicine and belongs to the category of lower Jiao damp heat.
The main cause of the disease is the lack of polyphenols in the body, such as vitamin B1, pantothenic acid, phosphoric acid, methyl salicylate and other components, which causes sugar metabolism disorders, a sharp increase in blood sugar levels in the body, and weakened metabolism.
Clinical experiments by Japanese medical doctor Goshichiro Ogawa and others have confirmed that regular drinking of tea can promptly replenish vitamin B1, pantothenic acid, phosphoric acid, methyl salicylate and polyphenols in the human body, and can prevent the occurrence of diabetes. For patients with moderate and mild diabetes, it can reduce blood sugar and urine sugar to very little, or completely normal; for patients with severe diabetes, it can reduce blood sugar and urine sugar, and alleviate various major symptoms.
The effects of Wutieguanyin on weight loss and bodybuilding. Obesity is a nutritional disorder that occurs with the continuous improvement of people's living standards. It is caused by excessive nutrient intake or insufficient utilization of energy stored in the body. of. Obesity not only brings many inconveniences to people's daily lives, but is also a cause of cardiovascular disease and diabetes. In 1996, the Fujian Provincial Institute of Traditional Chinese Medicine conducted a study on the weight loss effect of drinking Tieguanyin on 102 adult men and women with simple obesity. Studies have shown that Tieguanyin contains a large amount of tea polyphenols, which not only improves the effect of lipolytic enzymes, but also promotes 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, thereby reducing their weight. People's Hospital of Quanzhou City, Fujian Province used Tieguanyin slimming tea to treat 164 people suffering from obesity. They took 12 to 14 grams of slimming tea every day, and a course of treatment lasted for 15 days. After two courses of observation, the patient's blood lipids, triglycerides and cholesterol were significantly reduced, and his weight was also reduced. The total effective rate of treatment reached more than 70%.
6 The role of Tieguanyin in preventing and treating dental caries People generally believe 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 dental disease. There are many reasons for dental caries, one of the important reasons is that the teeth are poorly calcified, not hard enough, and easily damaged. Drinking tea can protect teeth and has been used in ancient my country. Su Dongpo of the Song Dynasty said in "Tea Theory": "Gargling with strong tea can not only relieve boredom, but also strengthen teeth and eliminate beetles." Modern scientific analysis shows that Tieguanyin is rich in fluorine, while ordinary food contains fluorine. The amount is very small. About 40% to 80% of the fluoride in Tieguanyin dissolves in boiling water, and it easily combines with the calcium in the teeth to form a layer of calcium fluoride on the tooth surface, which prevents acid and caries. Japan once conducted a survey on the dental caries rate among school-going children in two adjacent villages. The results showed that drinking Tieguanyin has a good effect on preventing and treating dental caries. Every school-going child drinks a cup of Tieguanyin every day, with a fluoride content of 0.4 mg, and if it lasts for one year, half of the children with dental caries will be cured. Statistics of students with dental caries in 100 primary schools in Japan showed that after switching to Tieguanyin, 55% of the students with dental caries were significantly relieved. It can be seen that drinking Tieguanyin has a preventive effect on people who do not have dental caries, and a therapeutic effect on people who have already had dental caries.
7. The bactericidal and anti-dysenteric effect of Tieguanyin. Folks in Anxi have long used Tieguanyin to treat dysentery and stomachache. There are also many records in ancient Chinese medical books about the use of tea to treat bacterial dysentery, red dysentery, white dysentery, acute enteritis, and acute gastritis. Why does Tieguanyin have the effect of sterilizing and stopping dysentery? Mainly tea polyphenols. After tea polyphenols enter the gastrointestinal tract, they can relax the tense function of the intestines and ease intestinal movement; at the same time, they can coagulate intestinal proteins, because bacteria themselves are composed of proteins, and tea polyphenols and bacterial proteins After encountering, the bacteria die and play a role in protecting the gastrointestinal mucosa, so it has the effect of treating enteritis.
8. The heat-clearing and fire-reducing effect of Tieguanyin. Tea is a good drink for preventing heatstroke and cooling down. Li Shizhen's "Compendium of Materia Medica" records: "Tea is bitter and cold,...it can best reduce fire. Fire is responsible for all diseases, and when fire falls, the upper body will be clear....Warm drinks will cause fire to drop due to cold air, while hot drinks will rise and disperse with the help of fire air." "In the dog days of midsummer, when the sun is in the sky and the heat is overwhelming, drinking a cup of cool Tieguanyin or a cup of hot Tieguanyin will make you feel cool physically and mentally, and help you relieve the heat. This is because the tea soup contains tea polyphenols, sugars, amino acids, pectin, vitamins, etc., which react chemically with the saliva in the mouth to moisturize the mouth, so it can produce fluid and quench thirst. At the same time, due to the effect of caffeine in Tieguanyin, a large amount of energy is emitted from the pores of the human skin. According to reports, drinking a cup of hot tea will dissipate heat through sweating through the pores of the human skin, which is equivalent to 50 times that of this cup of tea, so it can make people feel cool and relieve heat.
9. The refreshing effect of Tieguanyin on thinking and thinking. Almost everyone knows that drinking tea can refresh and improve thinking. There are many medical records in the past dynasties of our country, and the literati and eminent monks of the past dynasties all used their pens to praise the power of tea to refresh the mind and improve thinking. Bai Juyi's poem "To the Thirteenth King of East Neighbors" says: "Join hands with the moon by the pool, and the wind is under the open-necked bamboo. To drive away sorrow, you know the power of wine, and to break sleep, you can see the power of tea." The poem clearly mentions the power of tea to refresh people and break sleep. Su Dongpo's poem said: "Thirty pieces of Jiancha, no matter how it tastes, are given to Layman Bao to fight the Sand Devil in the monk's room." He said that giving Jiancha to Layman Bao would prevent him from dozing off during meditation. Drinking tea can improve thinking, so it is loved by people, especially writers, poets and other mental workers. For example, the great French writer Balzac, the Chinese-American female writer Han Suyin, and the famous Chinese writer Yao Xueyin all loved drinking tea to help them write and think.
Tieguanyin can refresh the mind and improve thinking, and its function mainly lies in the caffeine in tea. Caffeine has the function of stimulating the central nervous system, enhancing thinking, and improving efficiency. Therefore, drinking tea can break sleep, refresh your mind, relieve irritability, relieve fatigue, clear your mind, improve your thinking, and can significantly improve your oral defense ability and mathematical thinking response. At the same time, because Tieguanyin contains polyphenols and other compounds, it offsets the adverse effects of pure caffeine on the human body. This is also one of the important reasons why tea drinking has a long history, continues to flourish and develop.
Ten. The effect of Tieguanyin on sobering up alcohol and fighting smoke. It is also a well-known fact that tea can sober up alcohol and fight smoke. Wang Yangming, an acting scholar of the Ming Dynasty, famously said, "Just as you need tea to sober up after being drunk," it shows that our people have long recognized the efficacy of drinking tea to relieve hangovers. The ancients often "drink their sorrows with wine" and "sober up their hangovers with tea." Liu Yuxi, a poet of the Tang Dynasty, was drunk one day and remembered that Bai Juyi had "six classes of tea" to sober up his hangover, so he sent someone to give him something in exchange for tea to sober up his hangover. Later generations passed it down as a tea ceremony legend. The main component of wine is alcohol, and a glass of wine contains 10% to 70% alcohol. The polyphenols of Tieguanyin tea can offset each other with ethanol (the main component in wine), so drinking tea can relieve hangover. Tieguanyin can not only sober up alcohol, but also fight smoke. Because Tieguanyin contains a kind of phenolic acid, it can precipitate the nicotine in tobacco and excrete it from the body. At the same time, the caffeine in Tieguanyin can improve the liver's ability to metabolize drugs, promote blood circulation, excrete nicotine in the human blood through urine, and reduce and eliminate the side effects of nicotine. Of course, this effect is not just the single effect of caffeine, but the result of synergy with tea polyphenols, vitamin C and other ingredients.
