Actually, it won't do any harm. If so, it's because you drank too much.
Yunnan is located in the southwest of China, with subtropical climate, suitable climate and abundant rainfall. Excellent soil resources, very suitable for tea growth, belonging to a class of tea growth areas. There are very rich tea resources. Among them, Pu 'er tea is the most famous. Pu 'er tea is made of Yunnan big leaf tea tree, which is rich in many substances, including more than 30% tea polyphenols, more than 20% catechins, foam resistance and more than 40% extracts. As we all know, computer radiation is harmful to human body, and sitting for a long time is harmful to health and body shape. Tea polyphenols have anti-oxidation and anti-radiation abilities, and also have the function of losing weight. People who often use computers or surf the Internet should drink more Pu 'er tea.
Brahma (written in A.D. 1925) said: "Pu 'er tea is warm and fragrant, and can cure all diseases. Steamed and wrapped with bamboo sticks, the price is equivalent to gold. "Pu 'er tea, as a traditional beverage, can not only quench thirst, promote fluid production and refresh, but also has special medicinal effects. This has long been recorded in ancient books. Qing Zhao Xuemin's Compendium of Materia Medica says: "Pu 'er tea is warm and fragrant, producing six famous tea mountains: Youle and Gordon, among which Yibang and Manzhuan tea are more delicious. Bitter taste, greasy cattle and sheep poison, and it is forbidden for those who are weak. Bitter, expectorant, qi-lowering, laxative. Pu 'er tea paste is black as paint, and the first thing to sober up is green. Digestion and phlegm, clearing the stomach and promoting fluid production are particularly powerful. " In the sixth volume
Of course, this is not a hypothesis and association. The article also said: "We use human cancer cells cultured in vitro, and the effect of green tea is particularly obvious ... Under the microscope, Pu 'er tea can kill cancer cells, but green tea and black tea can kill cancer cells ... Pu 'er tea has the strongest effect on killing cancer cells, even when ordinary people drink tea 1%. After the action of Pu 'er tea, the cancer cells changed from polygonal concentration to round, and the shortened pseudopodia decreased, losing the ability of attachment and swimming, and even falling off, floating and losing. The remaining cells also become smaller and rounder, the nucleus is condensed, chromatin is condensed or disappeared, vacuoles appear in the nucleus and aggregates, nucleoli is condensed or fragmented and disappears, and chromosomes contract or condense with each other. Ribosomes decreased, mitochondria and endoplasmic reticulum expanded, DNA synthesis decreased and nuclear division stopped. These changes can prove that cancer cells often degenerate and die under the action of tea. "At the same time, according to the clinical trial of Kunming Medical College, Yunnan Pu 'er Tuocha was used to treat 55 cases of hyperlipidemia. Compared with Antoine's treatment of 3 1 case, Pu 'er tea has a higher curative effect than Antoine, and its cholesterol-lowering effect is similar to Antoine's, and there is no side effect after long-term use. Mi Le Carobbi, director of clinical teaching in the Department of Medicine of San Antonio, has proved through experiments that Pu 'er tea has an unexpected effect on fat metabolism.
Among the obese patients who drink Yunnan Pu 'er tea, more than 40% people lose weight in different degrees, and the effect is more significant in cases aged 40-50. 37% has a good effect on reducing lipid compounds contained in human body, 33% has a moderate effect, and has different effects on reducing triglycerides, cholesterol and hematuria. In addition, drinking Pu 'er tea can cause vasodilation, cerebral blood flow reduction and other physiological effects, and it is also used to prevent and treat diseases such as the elderly, hypertension and arteriosclerosis. Professor Beenaert Giacoto of Henri Lundo Hospital in Paris gave 20 patients with hyperlipidemia in Modao Hospital in creteil three bowls of Yunnan Pu 'er tea every day. A month later, it was found that the patients' blood lipids were almost reduced by a quarter, while those who drank the same amount of other teas remained unchanged. Professor Lv Dong of Orsay Institute of Nutrition and Physiology, who is also engaged in this experiment, said: "This kind of tea seems to have one or more special components that play a role in lipid metabolism."
The book "Pu 'er tea with peculiar efficacy" co-authored by Nobuyo and Ichiro Masuyama in Japan has set off a Pu 'er tea fever in Japan. 199 1 In the "International Symposium on Tea and Health" held in Shizuoka, Japan on August 26-29, participants showed great interest in the paper "Antioxidant Activity of Tetramethoxybenzene and Its Inducer in Black Tea" by Chinese and Japanese scholars, which aroused strong repercussions. Compatriots in Hong Kong and Macao believe that Pu 'er tea can quench thirst, strengthen the spleen and relieve alcoholism, stimulate appetite and eliminate food stagnation, inhibit bacteria and lose weight. Others think that green tea is cold: black tea is hot; Pu 'er tea is neither cold nor hot, it is economical and practical, and it is generally addictive, so it is called "Bao Li tea". Pu 'er tea is neutral and healthy, which is more suitable for the stomach of Hong Kong people. It may be the main reason why Hong Kong people prefer Pu 'er tea. Since most people are addicted to it, others will agree. Recently, Mr. You Yude, director of the Hong Kong and Kowloon Tea Merchants Association, summed up the reasons why Hong Kong people like to drink Pu 'er tea as "five points" (ten words): First, it is strong enough. The second is impact resistance, the third is warmth, the fourth is health, and the fifth is cheap. Pu 'er tea, imported from Japan, is processed into exquisite small package tea, which is very popular with the reputation of imperial concubine tea, beauty tea, bodybuilding tea, Qiaoqiao porcelain tea and Yishou tea. Pu 'er tea is called "the incredible eternal treasure tea". Nowadays, Tuocha, a beauty product, is sold in pharmacies and department stores in many western European countries, and it has also become a handicraft in home decoration. In France, some people even said, "Do you want a beautiful appearance? Then you have to drink tea. "
From the ancient description of the medicinal efficacy of Pu 'er tea to the update of modern physical and chemical research methods and means, we not only rely on empirical remedies and clinical efficacy, but also deeply study its mechanism from biochemistry, biophysics, molecular biology and genetics, and obtain reliable results from experimental animals. In recent years, Ina Kazuo and Liu studied the changes of characteristic aroma components and taste substances during the production of Pu 'er tea by biological and physical methods, which is helpful to explore the formation of special flavor and pharmacological effects of Pu 'er tea. The medicinal efficacy of Pu 'er tea has been widely used since ancient times. Today, being able to enjoy the reputation of "beauty tea", "slimming tea", "longevity tea", "my fair tea" and "slimming tea" in Japan, South Korea, Germany, Italy, Taiwan Province Province and Southeast Asia is really the most unexpected harvest except knowing how to stop and taste tea, and it is also doomed that Pu 'er tea will have a brighter future.
