Do you know the six benefits of Fuding white tea?

White tea belongs to micro-fermented tea, which is a rare variety of six traditional teas in China. Its birthplace is in Fuding City, Fujian Province, and its main producing areas are Fuding City, Zhenghe County and Jianyang County in the northeast of Fujian Province. But at present, its production method has been extended to many tea areas in China, and spread to India and other countries. The unique processing technology of Fuding white tea has created its finished tea full of white hair, plain and elegant brown color, light soup color, mellow taste, sweet taste, elegant aroma and fragrant quality. According to the different raw materials and processing technology of fresh leaves, white tea can be divided into five kinds: Baihao silver needle, white peony, Gongmei, Shoumei and new craft white tea. in recent years, tight products have appeared on the basis of traditional loose tea.

White tea has a cold taste and is a commonly used fire-lowering medicine among the people. since ancient times, there have been many records about white tea cool detoxification, treatment and maintenance of measles patients. Further research in modern medicine shows that, like other teas, white tea also has nutrition and health care functions, such as anti-oxidation, prevention of cardiovascular disease, regulation of immune function, anti-cancer and anti-cancer, anti-inflammation and detoxification, anti-allergy, anti-hypertension and so on. However, because of the endoplasmic biochemical components formed by its unique processing technology, it has the usual health effects different from other kinds of tea, such as "three drops and three resistances". What is the special effect of white tea? The so-called special means something different from the same kind or ordinary situation. The following let the editor combine some of the research results on the health care efficacy of white tea at home and abroad to come one by one for everyone.

1. Antibacterial and antimicrobial efficacy

M.Pilar and other studies found that white tea and green tea have the highest antimicrobial activity. The latest research from pace University in the United States shows that white tea extract has a preventive effect on the growth of bacteria such as staphylococcal infection, streptococcal infection and pneumonia. The results of Gilberto Santana-Rio and other studies showed that the germicidal efficacy of white tea was better than that of green tea, and the extract of white tea had a good inhibitory effect on salmonella.

two。 Anti-cancer, anti-cancer and anti-mutation effect

Research by the American Cancer Research Foundation shows that white tea has anti-cancer effect, and the intake of white tea can improve the body's immune function, and even inhibit and reduce the mass of liver cancer. Epidemiology and animal experiments show that tea can prevent gastrointestinal cancer. Gayle.An et al compared the inhibitory effect of green tea and white tea on intestinal tumor in mice and found that the mixture of white tea and sulindac had the strongest inhibitory effect on the tumor.

Gayle.An et al. also studied the role of white tea in antimutagenicity. The results show that white tea has the effect of anti-mutagenesis, and its inhibitory effect on mutagenesis is stronger than green tea, and stronger than any other kind of tea. Taking West Lake Longjing tea and Yunwu green tea as reference, Wang Gang evaluated the antimutagenic and in vitro anticancer effects of white peony and Baihao silver needle white tea. The antimutagenic properties of green tea and white tea were compared by Ames test. The results showed that the antimutagenic effect of white tea was better than that of green tea. The anticancer effect of white peony and Baihao silver needle was verified by MTT experiment. Under the treatment of 400g/mL concentration, the inhibitory effect of white peony and Baihao silver needle on the growth of AGS and HT-29 cancer cells was better than that of Longjing green tea and Yunwu green tea.

3. Blood pressure lowering effect

Because of its special processing technology, white tea retains the flavonoid quercetin, which is an important part of vitamin P and can significantly reduce vascular permeability. In addition, with the extension of storage time, the content of flavonoids in white tea increased obviously. Zhou Qiongqiong and other studies have shown that the flavonoid content of aged white tea is higher than that of white tea in that year, and the flavonoid content of 20-year-old white tea is significantly higher than that of other years, which is why white tea has "one-year tea, three-year medicine, seven-year treasure".

4. Hypoglycemic effect

Because of the special processing technology of white tea, the active enzymes necessary for human body but less in other kinds of tea are well preserved. Long-term drinking white tea can significantly improve lipoprotein lipase in human body, promote fat catabolism, effectively control insulin secretion, delay the absorption of glucose, decompose excess sugar in the body and promote the balance of blood sugar.

5. Improve immunity

Chen Yuchun and other studies have shown that white tea can significantly increase the serum level of mice, which is twice as high as that of American ginseng. The serum has triple biological activities of survival factor, differentiation and mitogen, which plays a key role in erythropoiesis. White tea can promote the production of spleen lymphocytes in experimental mice by 34.5% Mel 152.3%, thus prolonging cell life and increasing RNA and protein synthesis.

According to Chen rafters, the content of theanine in tea is compared with different kinds of tea, white peony is the highest, followed by Huangshixi Maofeng, Baihao silver needle, Junshan Silver Needle Tea, Xihu Longjing Tea, etc., while theanine is decomposed into ethylamine in the human liver. Ethylamine can mobilize human blood immune cells called gamma-delta T-shaped cells to respond against external invasion, and then T-shaped cells promote interferon secretion. Form a "chemical defense line" for the human body to resist infection.

6. Antagonizing the side effects of caffeine

The content of theanine in white tea ranks first among the six major teas (see Table 1 for details). According to Tsunoda T. It was reported that when the dosage of theanine was 1740mg/kg, it could significantly inhibit the excitation of nervous system induced by caffeine. In addition, caffeine shortens the sleep time caused by cyclophosphamide and barbital, and theanine counteracts this effect. Therefore, compared with other kinds of tea, white tea has less stimulation to the central nervous system.

In addition, L-theanine has a relaxing effect. There are four kinds of brain waves: δ-wave when sleeping, θ-wave napping, α-wave relaxation and β-wave excitation. The relaxation effect of L-theanine can be confirmed by measuring the change of α-wave, that is, the experimenter was given oral water and tasteless aqueous theanine solution (0.5~2mg/ml) respectively in a closed environment (room temperature 25 ℃, light intensity 40lx). The results showed that the amount of α-wave increased significantly with the increase of dosage. It shows that theanine has relaxing effect.

Of course, the above is only a brief list of the main health benefits of white tea. White tea has the above health benefits, but the true embodiment of these effects can not be achieved without adequate intake and relatively long-term and stable drinking habits. It is difficult to get the above benefits by tasting a couple of cups or occasionally holding a cup. In addition, I would like to add that white tea corresponds to the above-mentioned health care effect because of its internal characteristics, but it is still not deified or regarded as a panacea.
