The efficacy of Tieguanyin:
Tieguanyin 1. Detoxification and digestion, removing greasy food
Zheng Daoxi felt the long history of Anxi Tieguanyin and called it the "time-honored brand" of China tea family. Regarding its value, he first discussed "detoxification, digestion and oil removal". According to the article, tea is recognized as the best healthy drink for human beings. As early as the Western Han Dynasty, there was a record in Shennong's Classic of Materia Medica that "seventy-two poisons were encountered every day, and tea was used to solve them". In the 20th century, scientists discovered that there is a flavonoid mixture in tea, which has the function of sterilization and detoxification.
2. Beauty, weight loss and anti-aging
According to the article, medical research shows that Tieguanyin's crude catechin composition has strong anti-chemical activity and can eliminate reactive oxygen molecules in cells, thus protecting the human body from aging diseases. It is mentioned that the content ratio of manganese, iron, fluorine, potassium and sodium in Anxi Tieguanyin is higher than other teas, especially the high fluorine content ranks first among all teas, which has a remarkable effect on preventing and treating dental caries and osteoporosis in the elderly. 1979 and 1984, there were two "Oolong Tea Fever" in Japan, and Anxi Tieguanyin was known as "Beauty Tea" and "Diet Tea".
3. Preventing cancer makes smart people smarter
According to relevant scientific research results, Anxi Tieguanyin has a high selenium content, ranking first among the six famous teas. Selenium can stimulate immune proteins and antibodies to resist diseases and inhibit the occurrence and development of cancer cells. At the same time, Anxi Tieguanyin also has the effect of increasing wisdom. It is mentioned in the article that British scientists have found that the pH of human brain fluid is related to IQ. Tea is an alkaline drink, and Tieguanyin in Anxi is obviously alkaline. Regular drinking can adjust the acid-base balance of human body and improve people's IQ. In addition, the article also said that Anxi Tieguanyin is rich in vitamins, caffeine, amino acids, minerals and tea polyphenols. These substances have also been confirmed by scientific research, which are closely related to brain development and have a good influence on improving people's intelligence.
4. Be in a good mood to make friends and raise sex.
The article also analyzes the social attribute of Anxi Tieguanyin, and holds that Anxi Tieguanyin, as a kind of high-quality tea, has a unique effect in entertaining guests, making friends and cultivating self-cultivation. The article said that Anxi Tieguanyin needs brewing, and guests should wash cups. In the process of preparation, the host and guest should be caring and attentive and have a harmonious relationship; The guests catch up with the host while drinking tea, and the process is very harmonious and friendly. Therefore, programmed brewing and drinking can make people feel calm and help nourish their hearts and feelings.
Refreshing thinking
It is almost known that drinking tea can refresh you. There are many medical books in China in the past dynasties, and all the literati and monks in the past dynasties waved their wonderful pens and praised the refreshing and beneficial effects of tea. Bai Juyi's poem "To the Thirteen Kings of the East" said: "Chi Pan's moon is hand in hand, and bamboo is blowing. Drive away the sorrow and know the strength of the wine, and break the sleep and see the tea. " This poem clearly mentions the efficacy of tea in refreshing and breaking sleep. Su Dongpo's poem said: "Make thirty cups of tea, regardless of taste, and pack laymen with monks who beat sand people." He said that he would give the tea to Bao Jushi and let him drink it to avoid falling asleep during meditation. Drinking tea can be beneficial to thinking, so it is loved by people, especially some writers, poets and other mental workers. For example, Balzac, a great French writer, Han, a Chinese-American woman writer, and Yao, a famous writer in China, all like drinking tea to help their writing. Tieguanyin can refresh the mind, and its function mainly lies in caffeine in tea. Caffeine can excite the central nervous system, improve thinking and improve efficiency. Therefore, drinking tea can break sleep, refresh and relieve boredom, clear the mind, improve thinking, and significantly improve oral defense ability and mathematical thinking response. 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 and continuous development of tea drinking.
The role of Tieguanyin:
I. Anti-aging Effect of Tieguanyin Some scientific studies at home and abroad show that human aging is related to the peroxidation of unsaturated fatty acids in the body, and the peroxidation of unsaturated fatty acids is related to the action of free radicals. Free radicals with high chemical activity can make unsaturated fatty acids over-oxidized, make cell function mutate or decline, cause tissue proliferation and necrosis, and produce fatal diseases. Lipid peroxidation is the devil of human health, but the culprit is free radicals. As long as free radicals are removed, cells can grow and develop normally, and live a long and healthy life. Commonly used antioxidants are vitamin C and vitamin E, which can effectively prevent the over-oxidation of unsaturated fatty acids. Recently, Japanese researchers have shown that polyphenols in Tieguanyin can prevent excessive oxidation; Purine alkaloids can indirectly scavenge free radicals, thus achieving the purpose of delaying aging.
Second, the anti-cancer effect of Tieguanyin Cancer is an "incurable disease" that seriously threatens people's health today. Therefore, in recent years, the anti-cancer research of tea has aroused great interest and concern. A few years ago, it was reported 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, drinking tea to prevent cancer has been recognized by the world, and Tieguanyin is the best anticancer effect in tea. As early as 1983, Professor Tuonan Okuda of Okayama University in Japan had screened out the anticancer effects of dozens of plant polyphenols. The results showed that catechin (EGCG) had strong anticancer activity. Another scientist believes that Tieguanyin tea polyphenols are the main active ingredient in the study of confirming Tieguanyin's anti-mutation. In the study of chemical carcinogenesis, the preventive effect of Tieguanyin tea polyphenols has been affirmed. In addition, vitamin C and vitamin E in Tieguanyin can block the synthesis of nitrosamines, which plays a great role in the prevention and treatment of cancer.
Tieguanyin-Introduction
Tieguanyin is not only fragrant and mellow, but also a natural and delicious drink, and its health care function is also outstanding in tea. Modern medical research shows that Tieguanyin not only has the health care function of ordinary tea, but also has the functions of anti-aging, anti-cancer, anti-arteriosclerosis, preventing and treating diabetes, losing weight and bodybuilding, preventing and treating dental caries, clearing away heat and reducing fire, and relieving hangover. Tieguanyin was introduced from Anxi County, Fujian Province in the eighth year of the Republic of China, and it can be divided into "Tieguanyin with red heart" and "Tieguanyin with green heart". The main producing area is Wenshan period, with thick branches and loose leaves, few buds and thick leaves, and low yield. However, the quality of wrapped tea is higher, and the production period is five years later than that of Qingxin oolong tea. Isn't it a bit like a tree? The leaves are oval, thick and flat, which is suitable for Tieguanyin tea seed production.
Brewing method of Tieguanyin
Xu Cishu said in the Book of Tea in the Ming Dynasty: "Tea is nourished by water, stored in containers, and soup turns into fire. The four are connected and indispensable. " Tea, water, utensils and fire are all closely linked, which just echoes what we said about how to make good tea. Making tea seems easy. Put the tea in the pot, pour in hot water, wait a while, then pour it out, and you'll finish making tea! On the surface, Tieguanyin tea, like the decomposition action above, can get a good tea soup! However, the first step to make tea well is to look at tea, know tea and study its characteristics! In addition to the above written records, in the actual process of making tea, and in the face of different tea leaves and tea sets, it is necessary to distinguish carefully in order to get a good taste of tea soup. Anxi Tieguanyin tea has its own unique method of soaking and drinking. First of all, we must strictly use water and tea sets to brew Mishima Pass. "It is better to use a stone spring for water, a charcoal fire for stoves and a smaller tea set."
Brewing can be divided into eight channels according to its procedures:
1 White Crane Bath (washing cups): Wash the tea set with boiling water.
2 Guanyin enters the palace (dropping tea): Tieguanyin tea leaves are put into the tea set, and the amount of tea put accounts for about five points of the capacity of the tea set;
3 hanging the pot high (making tea): raise the boiling water and rush into the teapot or lid to turn the tea leaves;
4 spring breeze blowing (scraping foam): gently scrape off the white foam floating on it with a pot cover or pot cover to make it fresh and clean;
5 Guan Gong's tour of the city (pouring tea): pour the tea soaked for one or two minutes into the juxtaposed cups in turn;
6 Han Xin Dianbing (Tea): When the tea is poured to one point, it should be evenly dropped into each teacup bit by bit;
7 Taste the color of the soup (see tea): Observe the color of the tea in the cup.
8 sweet rain (drinking tea): take a hot sticker, smell its fragrance first, then taste its taste, smell it while sipping, and pour it gently. Although you don't drink much, you can leave the fragrance on your teeth and cheeks. The bottom of your throat is sweet and makes you feel relaxed and happy. In the process of making tea, Tieguanyin in Anxi, Fujian and Tieguanyin in Muka, Taiwan Province have different rope-like appearance and baking degree after making tea, and also have their own characteristics in tea soup performance, especially in soaking methods. Now the main points are as follows:
Drinking method and use of Tieguanyin
Tieguanyin is best soaked in a bowl, and the water should be soaked in pure water as much as possible. The water temperature is about 90 degrees. The first time the water was washed with tea and a warm cup, the second time the water was fragrant for fifteen seconds. After that, every water is postponed for fifteen seconds.
It is best not to drink more than seven courses of tea. If spring tea is basically five courses, it belongs to tea residue and has no obvious tea fragrance. Although it has no health care function, Tieguanyin tastes better the longer it lasts, and the aftertaste of tea is unique to good tea.
Therefore, the taste of new tea is good, and good Tieguanyin is sour. After a long time, the sour taste will gradually lose.
The newer the new tea, the better. Improper drinking 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 also 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 it 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.
