Old people should not drink strong tea. Because tea contains more caffeine with exciting effect, the elderly drink too much strong tea, which is prone to tachycardia, arrhythmia, elevated blood pressure, and even myocardial infarction and stroke. Drinking a lot of tannic acid in strong tea will not only slow down intestinal peristalsis, but also precipitate protein and metal ions, causing constipation and iron deficiency anemia. In addition, drinking a lot of strong tea will also stimulate gastric mucosal inflammation and even induce ulcers.
People with peptic ulcer and gastrointestinal dysfunction should not drink tea; It is best for patients with hypertension to drink green tea, because among all kinds of teas, green tea contains less caffeine and more polyphenols, and tea polyphenols can eliminate the pressor effect of caffeine; Old people with good constitution and obesity should drink green tea, and old people with weak constitution and cold stomach should drink black tea.
It is not advisable to drink tea after meals, so as not to dilute gastric juice and affect digestion; It is not advisable to drink tea before going to bed, so as not to be too excited and cause insomnia; Overnight tea is not suitable for drinking, because it is easily contaminated by microorganisms and contains more harmful substances.

After drinking tea, I can still have some ideas. Hehe, here are some ideas about tea, which I hope to share with my friends.
Chinese medicine believes that green tea is cool, black tea is hot, and scented tea is in between, neutral. Children drink green tea and scented tea, old people drink black tea, and normal adults have no side effects.
Tea is an oriental culture, characterized by correct discrimination. Just like thousands of years ago, China people put forward that the world is a black-and-white dichotomy of Tai Chi, it is just an imagination, and there is no precise definition. Westerners are different. The binary of western culture accurately describes our world through computers. Therefore, tea has no accurate data description and needs everyone's understanding.
The tea ceremony formed in such a culture without formula and data is mysterious. Because mystery brings infinite reverie. Tea ceremony becomes beautiful. Actually, drinking tea is very simple. You can drink it in your mouth by pouring tea and water. When drinking tea becomes a kind of etiquette, drinking tea becomes a kind of tea culture, and it becomes an act of walking around the streets, elegant.
China people drink tea: the first step is to prepare utensils for use, the second step is to warm the pot and light it, the third step is to let Oolong enter the palace, the fourth step is to hang the pot high, the fifth step is to return the jade liquid to the pot, and the sixth step is to pour the tea.
The spirit of tea ceremony, every place has its own stress. The Tea Association of the Republic of China speaks clearly, respectfully, elegantly and truly; Chinese tea art pays attention to quiet beauty; Kaohsiung tea art emphasizes moderation, frugality, nourishing qi and taste; Japanese also have tea ceremony, but I really hate Japanese, even Japanese tea ceremony. To sum up, drinking tea not only seeks external purity, but also inner peace, tranquility, incorruptibility and shame; Humble yourself while respecting others; Pursue true knowledge and truth, keep nature and get rid of material desires; Righteousness, yearning for kindness and so on. ...
Drinking tea can not only cultivate temperament, but also prolong life, resist aging and keep fit. Tea is rich in caffeine, tea polyphenols, vitamins, minerals and amino acids. Drinking tea regularly can resist aging, regulate immunity, prevent cancer and cancer, prevent cardiovascular diseases, detoxify and nourish skin, induce diuresis and relieve fatigue.
Top ten famous teas in China:
Hangzhou Longjing, Longjing tea with "lion (peak), dragon (well), cloud (home), tiger (running), plum (home)" in the first place, with West Lake Longjing tea as the most. Longjing tea is straight and sharp, flat and handsome, smooth and even, and yellow in color. After brewing, the aroma is high and lasting, and the fragrance is fragrant; Tangse apricot is green, clear and bright, with light green leaves and upright buds, which are lifelike. Tea soup is refreshing, fragrant between teeth, and endless aftertaste.
Dongting Biluochun is produced in Dongting Mountain, Taihu Lake, Wuxian County, Jiangsu Province. Taihu Lake is vast, with clear water and wide smoke. Dongting Mountain is located on the bank of Taihu Lake. Dongshan is a peninsula, just like a huge ship stretching into Taihu Lake. Xishan is an island standing in the lake, several kilometers apart. Xishan has a mild climate, warm in winter and cool in summer, fresh air and misty clouds. It is a unique environment for the growth of tea trees, and with fine picking and exquisite technology, it has formed unique quality characteristics. Biluochun tea strips are slender, curled into snails, covered with fine hairs and green in color. After brewing, the taste is fresh and smooth, the fragrance is fragrant, the soup color is clear and the leaves are even and tender. Especially for the senior Biluochun, you can flush the water before putting the tea, and the tea still sinks slowly, and the leaves are scattered and fragrant. This is a strong performance of tea buds, which is incomparable to other teas. Therefore, there is a folk saying that "Biluochun" has been "copper wire strips, spirals, long hair all over, tender (referring to bud leaves) and three fresh (referring to color, fragrance and taste) since ancient times."
Huangshan Mao Feng and Huangshan Mao Feng Tea Garden are located around Yungu Temple, Songgu Temple, Suspension Bridge Temple, Ciguang Pavilion and Banshan Temple, with an altitude of1.200m and a hillside of 30-50 degrees, and are located in the deep valley of the mountain dock. The climate here is mild, the rainfall is abundant, the soil is fertile, the upper layer is deep, the air humidity is high and the sunshine time is short. Under this special condition, the tea tree is immersed in clouds every day, so the tea buds are particularly plump, soft and tender, with thick leaves, durable foam resistance, rich aroma and sweet taste, and become the top grade of tea; Lushan mountain fog.
Others include Anxi Tieguanyin, Junshan Silver Needle, Yunnan Pu 'er Tea, Lushan Cloud, Frozen Top Oolong, Qimen Black Tea, Sakura Jasmine Tea and so on. Others think that the melon slice tea in Lu 'an, Anhui, Maojian tea in Xinyang, Henan are also good teas, and there are more than a dozen good teas in China.
Good tea is mostly produced in places with pleasant climate and favorable conditions. Suzhou accounts for two of the top ten famous teas, which shows that Suzhou is a good place for outstanding people. Speaking of history and culture, Shanghai should be far behind Suzhou, so the World Heritage Conference will be held in Suzhou instead of Shanghai.
Drinking tea is better than drinking. It's easy to make trouble in a bar, and it's easy to enter a teahouse.
With the progress of science and technology, tea is no longer the best in the wild. The emergence of organic tea has brought about a revolution in tea. The tastes of compound teabags, such as Qinxing Tea Pull, Meiyan Tea Pull and Xianyang Tea Pull, are also unique. There are also tea drinks, Wasai, and tea drinks of various flavors will definitely refresh people who like tea. You don't have to make a fuss. Whenever you want to drink, you can drink all kinds of tea in the supermarket, which saves trouble, time and money.
Tea can be used not only for flushing toilets, but also for cooking and making snacks. It's also delicious, like the famous tea eggs. I also saw a lot of tea seeds this year. Maybe I will see some tea snacks, tea noodles and tea bread in the future. Tea is really a good thing and a kind of culture.
