Tea, people into the vegetation, melt in the landscape

Know tea, taste tea, benefit from tea

Compared with other kinds of tea, the functional components and health care mechanism of white tea are unique. The pharmacology of traditional Chinese medicine has proved that white tea is cold and cool, clearing away heat and reducing fire, dispelling summer heat and detoxification, and has the function of auxiliary treatment.

Tea polyphenols

Its chemical properties are quite active, but the processing of white tea does not destroy or promote the activity of enzymes, withering promotes the water loss of bud leaves and leads to the damage of cell membrane of fresh leaves, polyphenols come into contact with polyphenol oxidase, and catechins naturally oxidize slowly, thus forming the unique quality of white tea.

Modern studies have shown that tea polyphenols have many health effects, such as anti-oxidation, lipid-lowering, antibacterial, blood pressure-lowering, blood-lipid-lowering, anti-aging and so on.

Caffeine

White tea is rich in caffeine, which can relax blood vessels, promote blood circulation, stimulate central nervous system, prevent hypertension, headache, myocardial infarction and other pharmacological and physiological effects. It is an important source of medical caffeine.

Caffeine itself has antioxidant effect. Compared with tea polyphenols, caffeine has a synergistic effect on human cancer prevention and anti-cancer.

Theanine

White tea has high amino acid content. The main component of tea amino acid is theanine. Theanine has the functions of improving immune system function, anti-tumor, controlling excessive anxiety, improving learning efficiency, increasing nerve sharpness in the body, improving attention and so on.

Tea pigment

In the process of white tea processing, tea polyphenols were naturally slowly oxidized to form some tea pigment substances, especially the new process white tea processing was kneaded and rolled, and the degree of oxidation of tea polyphenols was increased to form more abundant tea pigment substances. And white tea, after years of storage into the process of old white tea, theaflavins, lycopene and other substances will also increase.

Tea pigment contains a large number of active phenolic hydroxyl groups and other active factors, which has a strong effect of scavenging free radicals and antioxidation. It has a variety of health effects, such as prevention of cardiovascular and cerebrovascular diseases, anti-ultraviolet radiation, anti-oxidation, anti-atherosclerosis, anti-caries, anti-bacteria and anti-virus.

Research results on the health care function of white tea abroad

Dr. Bukowski of Harvard Medical School, an American scientist, has found that drinking white tea increases the amount of interferon secreted by immune cells in the body's blood by five times.

Milton of pace University in New York, USA. According to Dr. Schiffenberg's latest research, white tea extract can prevent the growth of bacteria such as staphylococcal infection, streptococcal infection and pneumonia.

Dr. Lodke, an American biochemist, concluded that white tea has more anticancer substances than other teas, which can constantly inhibit and reduce the mass of liver cancer and improve immune function.

Domestic research results on the health care function of white tea

In 1995, China Native products and Animal products Fujian Tea Import and Export Corporation provided samples of white tea and white peony. Fujian Institute of traditional Chinese Medicine conducted experiments on the health care function of Fujian white tea. The results are as follows:

The analysis of the anti-lipid peroxidation effect of white tea on CIR mice shows that white tea can significantly reduce the level of lipid peroxidation in liver and brain tissue, and has a good antioxidant effect.

Effects of White Tea and White Peony on body weight, Grain consumption and body Fat in mice, it is speculated that drinking appropriate concentration of white tea soup is beneficial to body fat and weight loss.

The results of "study on white tea reducing serum total cholesterol and triglyceride in mice" show that white tea soup can significantly reduce serum total cholesterol and triglyceride without affecting body weight, especially its 1% concentration is better, which is beneficial to the prevention and treatment of hyperlipidemia.

"study on the effect of white tea and white peony on the activity of serum glutamic pyruvic transaminase in mice against carbon tetroxide poisoning" shows that drinking white tea can significantly increase the hepatoprotective function of the body.

The results of Dr. Yuan Dishun of China White Tea Research Institute of Fujian Agriculture and Forestry University showed that white tea had good hepatoprotective effect and could significantly reduce the contents of transaminase and malondialdehyde in mice injured by carbon tetroxide.

Chen Yuchun, a researcher of Fujian Institute of traditional Chinese Medicine, has shown that white tea can significantly increase the level of serum EPO in experimental mice, play a key role in cell production, prolong cell life, and increase RNA and protein synthesis.

In 2011, it was led by Professor Liu Zhonghua, Director of the National Plant functional components Utilization Engineering Research Center and Professor of Hunan Agricultural University. Integrating the National Plant functional components Utilization Engineering Technology Research Center, the traditional Chinese Medicine Modernization Research Center of Tsinghua University, the Aging Medical Research Center of Peking University, the Tea key Laboratory of the Ministry of Education and the Sub-Health intervention Technology Laboratory of the State Administration of traditional Chinese Medicine and five well-known institutional technical resources and scientific research teams, taking Fuding White Tea White Silver Needle White Peony as the research object, after more than a year Dozens of rigorous and scientific analytical demonstrations have been carried out, and the scientific research results have proved that Fuding white tea has significant health effects, such as beauty and anti-aging, anti-inflammation and clearing fire, reducing fat and weight loss, lowering blood sugar, regulating uric acid, protecting liver, resisting virus and so on.

In June and August 2012, Professor Liu Zhonghua announced this important scientific research achievement to the participants at the Beijing International Tea Exhibition and the "Fuding White Tea Health Care efficacy Research results Conference" held in Hangzhou, respectively. this is the systematic research and release of the results of national authoritative scientific research institutions on the health efficacy of white tea.

Han Chi, chairman of the Food Toxicology Committee of the Chinese Toxicology Society and researcher Han Chi of the Food and Nutrition Research Institute of the Chinese Center for Disease Control and Prevention, mentioned in his project "the preventive effect of tea on cancer, cardiovascular disease and diabetes": in the study of the protective effect of Fuding white tea on cardiovascular disease, systematic and in-depth studies were carried out from three aspects: in vitro experiments, whole animal experiments and human trials.

These studies of Han Chi have reached the international advanced level. And on this basis, two population intervention trials were carried out. The results showed that drinking Fuding white tea could reduce the risk factors of cardiovascular disease, reduce the levels of serum triglyceride and total cholesterol in people with abnormal blood lipid metabolism, slow down thrombosis, reduce DNA oxidation damage, and reduce lipid peroxidation damage, so as to maintain the normal function of cardiovascular system and reduce the risk of cardiovascular and cerebrovascular diseases. This study fills the gap in the protective effect of white tea on cardiovascular system in the epidemiological data at home and abroad.

In the aspect of auxiliary hypoglycemia, most of the studies at home and abroad are animal experiments, and most of them take tea extracts (such as tea polysaccharides and tea polyphenols) as the research object, and there are no experiments on tea directly given to experimental animals.

Han Chi's research is consistent with the way of human contact by drinking tea as a way of giving. The hypoglycemic effect of Fuding white tea was studied from two aspects of animal and human experiments. Direct tea drinking is adopted. Through the establishment of hyperglycemia animal model, it was confirmed that Fuding white tea could reduce fasting blood glucose and increase glucose tolerance in hyperglycemia animals, and through population intervention trial, Fuding white tea could significantly improve the clinical symptoms of patients with type 2 diabetes. reduce fasting blood glucose and 2-hour postprandial blood glucose, promote insulin secretion. That is, both animal and human experiments show that white tea has a certain auxiliary hypoglycemic effect.

The results of the study show that Fuding white tea has an auxiliary hypoglycemic effect, which is of great significance for further population intervention research. The research result won the second prize of the Science and Technology Award of Chinese Preventive Medicine Association in 2011.

The love and affection of tea experts for white tea

Tea industry leader Zhang Tianfu (108 years old) talked about his love and love for white tea and his experience of drinking white tea and enjoying health at a tea reception in Fuzhou in 2010. He smiled and said, "when a guest comes to my house for tea, I always make him 10 cups of tea." Among the ten cups of tea, the first cup is Baihao silver needle. Experts at home and abroad are invited to give a lot of gifts when they come to my house for tea, but if I make ten cups of tea, the first cup is a Baihao silver needle. "

Researcher Luo Shaojun has repeatedly called for attention to the development of white tea, she said: "not only the United States, Sweden, Stockholm Medical Research Center shows that white tea sterilization and elimination of free radicals are very strong." I tried my best to promote white tea 30 years ago, and today I have to make a loud appeal. " White tea is used as a good medicine with the effects of heat-clearing and detoxification, anti-inflammation and summer heat in Fujian tea area and North China, so the ancients' work is the same as rhinoceros horn'. In fact, many health and health effects of white tea are like wild ginseng, and it can also improve the immune function of the human body. The effect of white tea with storage time of 5 Mel for 15 years is better. Its effective functional ingredients, such as flavonoids, theanine, tea polysaccharides and theophylline, have higher contents and unique aroma, especially the scent of roses, so many people at all times and at home and abroad like to collect white tea. "

Chen Jinshui, a veteran tea expert and former secretary-general of Fujian Tea Association, took out the Baihao silver needle which won the "national famous tea" at the first national famous tea review meeting held by the Ministry of Commerce in 1982 at the Fuzhou tea tasting meeting of 100 journalists. This is a bottle of Baihao silver needle that has been preserved for 30 years. The silver needle in the bottle is still covered with white hairs, buds fat and without deterioration. Recalling the scene of that year, he said: "since the late Qing Dynasty, Beijing Tongrentang has bought 50 jin of aged white tea every year for dispensing medicine. In the era of planned economy, the state allocated white tea to the tea department of Fujian Province every year for drug introduction (compatibility) to the State Pharmaceutical Corporation and prepared into a very high-grade medicine. "

Dr. Wang Yuefei of the Tea Department of Zhejiang University also holds the same point of view. He said: "White tea is a kind of micro-fermented tea with natural processing technology, so there is relatively less loss of tea polyphenols and more active ingredients are retained. Tea polyphenols are the main ingredients that tea can resist radiation. Fuding white tea has a relatively high content of polyphenols. Drinking 3 cups of white tea a day can have an anti-radiation effect. Therefore, in 2011, after the March 11 earthquake in Japan, the government of Fuding City and tea enterprises urgently allocated a batch of Fuding white tea to Tokyo by international express mail, giving Fuding white tea with radiation protection, anti-radiation and other health effects to the Chinese Embassy in Japan, which is firmly in the front line of earthquake relief. After receiving this batch of tea, the Chinese Embassy in Japan said that it was a "timely help" from the people of the motherland at a critical moment.
