Strawberry tea, commonly known as Mao Yan strawberry tea and Tujia nectar tea, is a perennial vine with the medicinal name "Ampelopsis grossedentata", which can be used as both medicine and drinking. It is clearly recorded in Pharmacopoeia such as Preserving Materia Medica and National Collection of Chinese Herbal Medicine that raspberry tea is green and first frost, and its drinking effect has obvious health care and therapeutic effects. Historically, it was called "rattan tea", "white tea" and "divine tea". It has the taste and medicinal function of tea, and can adjust renal function if drunk frequently, and has a good preventive effect on cardiovascular and cerebrovascular diseases, rheumatism and rheumatoid diseases. Dihydroflavonol has the functions of anti-hypertension, antitussive, expectorant, reducing blood lipid and protecting liver, which is unique to wild strawberry tea. According to the pharmacological analysis of traditional Chinese medicine, raspberry tea is rich in 36.2% flavonoids, including organic acids, glycosides, phenols, dihydromyricetin, salicin and so on. It can scavenge free radicals and block the peroxidation of lipid compounds, thus maintaining the normal function of cell membrane and playing the role of beauty and anti-aging. Dihydromyricetin contains a lot of therapeutic components and has the characteristics of vitamin P. It can protect blood vessels from injury by reducing the permeability and brittleness of blood vessels, which is related to the antioxidant function of strawberry tea, because the damage of blood vessels is caused by oxidative damage of cells. Therefore, the effective rate of strawberry tea in treating hyperlipidemia and hypertension is 9 1.7%. According to scientists, bitter food is the source of vitamin B 17, which has a certain killing effect on cancer cells. According to long-term folk drinking practice and modern scientific research, raspberry tea set has the functions of promoting fluid production to quench thirst, moistening throat and lungs, protecting liver and nourishing blood, reducing deficiency fire, helping digestion, diminishing inflammation and detoxifying, lowering blood pressure and losing weight, moistening skin and beautifying face. Especially suitable for obese and smokers and drinking after drinking. What are the benefits of drinking green tea? First of all, we must understand the ingredients of green tea. It has been proved by modern scientific research that green tea contains more than 450 kinds of organic compounds and 15 kinds of inorganic minerals, most of which have the effects of health care and disease prevention. 1, reducing fat and weight, preventing cardiovascular and cerebrovascular diseases. Drinking tea is closely related to losing weight. As early as more than 2,000 years ago, Shennong Materia Medica mentioned the slimming effect of tea: "Long-term service, peace of mind, benefiting qi ..... intellectual man fit and not old". Modern scientific research and clinical experiments have proved that drinking tea can reduce blood lipid and cholesterol and make the body lighter. This is because the comprehensive coordination of phenolic derivatives, aromatic substances, amino acids and vitamins in tea, especially the comprehensive function of tea polyphenols, theanine and vitamin C, can promote fat oxidation, help digestion and reduce fat and weight. In addition, tea polyphenols can dissolve fat, while vitamin C can promote cholesterol excretion. Green tea itself contains tea gan ning, which can improve the toughness of blood vessels and make them not easy to rupture. A study published in the Journal of Circulation of the American Heart Association in May 2002 shows that drinking tea regularly can reduce the risk of dying of heart disease. Researchers from Harvard Medical School in the United States conducted a follow-up survey on 1900 patients with heart disease, mainly the elderly over 60 years old. The survey found that those who drink more than 65,438+04 cups of tea per week have a lower risk of death within about three and a half years after a heart attack than those who don't drink tea. The study also shows that even if patients drink less than 14 cups of tea per week, it may reduce the death rate of heart disease by 28%. 2. Anti-cancer. Green tea contains tea polyphenols and caffeine, which have comprehensive effects, not only refreshing, but also improving human immunity and anti-cancer. In recent years, the American Chemical Society has always found that tea has an inhibitory effect not only on digestive system cancer, but also on skin, lung and liver cancer. It has been confirmed by scientific research that the organic anticancer substances in tea mainly include tea polyphenols, theophylline, vitamin C and vitamin E; The inorganic anticancer elements in tea mainly include selenium, molybdenum, manganese and germanium. Scientists in China and Japan believe that catechins in tea polyphenols have the best anticancer effect. 3. Anti-poison sterilization. The use of tea as a good antidote can be traced back to the ancient Shennong era (about 2737 BC). The saying that "Shennong tasted a hundred herbs and encountered 72 poisons every day, and solved them with tea" is recorded in Records of the Historian Huang San, Huai Nan Zi Xiu Wu Xun, Herbal Yi Yan and other books. Cha Sheng Lu Yu pointed out in the Book of Tea, the world's first authoritative work on tea science, more than 1200 years ago (AD 780), "Tea is the most suitable drink because it is cold ... If you feel hot, thirsty, stuffy, headache, tired eyes, tired limbs and uncomfortable joints, drink it four times. The above symptoms listed by Lu Yu are very close to typical pneumonia or suspected cases. Chen Zangqi, a medical scientist in the Tang Dynasty, wrote in Materia Medica: "Quench thirst and eliminate epidemic diseases. Expensive tea also. Liu Ye, a famous eunuch, listed "eliminating furuncle with tea" as one of the ten virtues of tea. Since the Tang Dynasty, there has been a new narrative in the study of tea by doctors in past dynasties, which is similar to detoxification and sterilization with tea. However, due to the underdeveloped science at that time, infectious and epidemic diseases were collectively called "plague" or "furuncle". Although bacteria and viruses are not specified, it has been proved that drinking tea is helpful for detoxification and sterilization. The research on the health care function of tea has been deepened in modern medical circles. In 2003, American scientists reported in the Journal of the American Academy of Sciences that "the chemical substance named' theanine' in tea can enhance the anti-infection ability of human body by five times". 4. Long life. The anti-aging effect of green tea on human body is mainly reflected in the coordination of several effective chemical components and various vitamins, especially tea polyphenols, caffeine, vitamin C, aromatic substances, lipopolysaccharide and so on. , can enhance human myocardial activity and vascular elasticity, inhibit arteriosclerosis, reduce the incidence of hypertension and coronary heart disease, enhance immunity, thus anti-aging and longevity. Medical research shows that tea polyphenols can not only reduce the contents of cholesterol and triglycerides in blood, but also enhance the toughness and elasticity of microvessels and reduce blood lipids, which is extremely useful for preventing and treating common diseases of middle-aged and elderly people such as hypertension and cardiovascular diseases. Tea contains selenium, and it is organic selenium, which is more easily absorbed by people than selenium in grain and oil. Dr Richard Paixiwat of the United States believes that adding selenium to food, combined with vitamin C and vitamin E, can prolong people's life, and tea is rich in these strange elements that are beneficial to life. Birth, old age, illness and death are irresistible laws. The so-called "longevity" is false, and "longevity" is true. There are countless examples of longevity by drinking tea. According to Song? 6? 1 Qian Yi's Nan Xinshu records that in the third year of Emperor Xuanzong of the Tang Dynasty (AD 849), there was an old monk in his thirties in Du Dong (now Luoyang, Henan). The emperor asked him how to keep in good health. He said, "I am a young minister and I don't know anything about medicine. I am kind by nature. All I ask is that tea is everywhere, or I meet more than 100 bowls of tea every day. "Qianlong is the longest-lived feudal emperor in China. He reigned for 60 years and lived to be 89 years old. Drinking tea is one of his health recipes. Su Juxian, the oldest birthday girl in Shanghai and the last scholar in the late Qing Dynasty, insisted on drinking tea as a big habit all his life. He lived to the age of 108 (according to the radical of the Chinese character "tea", it can be divided into "rice" and "eighty-eight", which is 108). 1994 Yuan Dunzi and Wang, a couple aged 104 who won the title of "Longevity Couple" in Shanghai, also drink tea every day, usually at 10 and 3 pm every morning. Zhang Shun, a centenarian born in 1896, Gaozhou, Guangdong Province, has four noes: no smoking, no drinking, no gluttony and no picky eaters. " Sixi likes coarse grains, sweet potatoes, jealousy and tea. 1898 Born in Fengshun County, Guangdong Province on August 20th, Zhang is a hardworking and long-lived woman who never smokes, drinks or drinks tea. Professor Wu Juenong, honorary chairman of China Tea Society, known as "contemporary Cha Sheng", celebrated his 90th birthday. When talking about the mystery of longevity of himself and his wife, he gave the answer of drinking more tea and eating more fruit. (Press: Wu Lao lived to be 9 1 year old, and his wife Chen lived to be 98 years old. ) The famous mathematician, consultant of Shanghai Tea Society and Professor Su of Fudan University lived to be 65,438+0,065,438+0 years old. Drinking tea after breakfast every morning is a way for him to live a long and healthy life. Mr. Cui Guiyong, President of Luyu Tea Classics Research Association of Korea, loved tea on weekdays and lived to 100 years old (died on April 5, 2002). In the northwestern Indian city of Gapur, there was an old man named Habibou Mian, whose age was officially recognized by the local government as 125. When telling the secret of his longevity, the old man Mian talked about his eating habits. "I never smoke. Drinking tea is my only addiction." There is a farmer's birthday girl named Zanadi michal in Egypt. He drinks more than 6 cups of tea every day, but he is lucky to live to be 130! Deng Xiaoping, a politician with ups and downs, loves to drink green tea. Deng Xiaoping's sister Deng Xianqun once recalled Deng Xiaoping's life during the Cultural Revolution and said, "My eldest brother likes drinking tea. He likes to drink green tea produced in Sichuan and Anhui, and sometimes drinks West Lake Longjing tea. Tea is still relatively expensive. He put a lot of tea in the cup, which will take up two-thirds of the cup when it is completely soaked. My eldest sister-in-law makes a cup of strong tea for my eldest brother every morning. When my eldest brother finishes drinking, my eldest sister-in-law will continue to drink the remaining tea roots and make him another cup in the afternoon. " The ancients called tea a medicine for all diseases. Tea can preserve health and prolong life, but it is important to persist and persevere, and you will see the effect. Drinking tea has a hundred benefits but no harm. It's hard to say which kind of tea is good, but choose according to your own physique and preferences.
