The newer the new tea, the better. Improper drinking can easily hurt the stomach. Because new tea has just been picked, it has a short storage time and contains more unoxidized polyphenols, aldehydes and alcohols, which has little effect on healthy people. But for patients with poor gastrointestinal function, especially those with chronic gastrointestinal inflammation, these substances will stimulate gastrointestinal mucosa, and people with poor gastrointestinal function are more likely to induce stomach diseases. Therefore, it is not advisable to drink more new tea, and do not drink new tea that has been stored for less than half a month.
In addition, new tea also contains more caffeine, active alkaloids and various aromatic substances, which will also excite people's central nervous system. Patients with neurasthenia and cardiovascular and cerebrovascular diseases should drink it in moderation, not before going to bed or on an empty stomach. The correct way is to leave it for half a month before using it. People who are usually easily excited or sensitive, have poor sleep and are weak should drink less or not drink tea at night.
Time and taboo
It is best to drink tea after meals, because drinking tea on an empty stomach will harm your health, especially for people who don't drink tea often, it will inhibit the secretion of gastric juice, hinder digestion, and seriously cause palpitations, headaches and other "tea drunk" phenomena. In addition, when drinking tea at night, you should put less tea leaves and don't make the tea too strong.
It should be noted that you must not drink overnight tea. In addition, the temperature is generally high in summer, so tea should not exceed 12 hour. You can't make tea in a thermos cup to avoid the loss of nutrients.
Berberine and tea cannot be eaten at the same time. Do not drink tea within 2 hours before and after taking berberine. Tea contains about 10% tannin, which is an alkaloid precipitant, and can combine with alkaloids in berberine to form insoluble tannin precipitate, which reduces the efficacy of berberine.
Drinking tea on an empty stomach will dilute our gastric juice, leading to a decline in digestive function, resulting in palpitation, dizziness, headache, fatigue and other phenomena.
It should also be noted that tea is an irritating drink, which contains tannic acid and caffeine. Teenagers should not drink tea. And girls should not drink tea in six stages according to their own physique:
1, when the monthly physiological period comes;
2. Pregnant women are pregnant;
3. Before the pregnant woman is about to give birth;
4. Mothers who want to breastfeed themselves just after giving birth;
5. Be a wet nurse;
6. menopausal women.
Please pay special attention to:
1. Avoid drinking hot tea and herbal tea (cold coagulation and phlegm accumulation).
2. Avoid excessive brewing times (after 3 or 4 times, there is basically no tea juice, and the trace harmful elements contained in it are brewed last)
3. Avoid drinking tea before meals (tasteless diet reduces the function of digestive organs to absorb protein), and drink tea immediately after meals (which affects the absorption of protein and iron).
Tea and season
Most parts of China have a monsoon climate with four distinct seasons: high temperature in spring, hot in summer, cool in autumn and cold in winter. So drinking tea in different seasons should be adjusted accordingly. Generally speaking, it is recommended to drink scented tea in spring, green tea in summer, green tea in autumn and black tea in winter.
It is advisable to drink scented tea in spring, which can disperse the cold evil accumulated in the body all winter and promote the hair growth of human yang; It is advisable to drink green tea in summer. Green tea tastes bitter and cold, and it can clear away heat and relieve summer heat, detoxify, enhance gastrointestinal function, promote digestion, prevent diarrhea and skin boils infection. Green tea should be drunk in autumn. Green tea is neither cold nor hot, which can completely eliminate the residual heat in the body and make people feel refreshed. It is advisable to drink black tea in winter, which is sweet and rich in protein and has a certain nourishing effect.
◆ Drink scented tea in spring
In the days of spring, the spring breeze recovers, and the sun is the spirit, bringing vitality to everything. But at this time, people generally feel sleepy and weak, and there is a phenomenon of spring sleepiness.
People drinking scented tea can alleviate the adverse effects of spring sleep. Scented tea tastes sweet and cool, but its fragrance is pungent, which is beneficial to dispel the cold evil accumulated in the human body in winter, promote the growth of yang in the body, make people feel refreshed and make the "spring sleep" disappear on its own.
Scented tea is a treasure in tea that combines the beauty of tea taste and the beauty of flowers. "Flowers attract tea fragrance to complement each other" is made by mixing tea and flowers by using the principle of aroma absorption characteristics of tea such as fried green tea and fragrance spitting characteristics of flowers, among which jasmine tea is the most famous. This is because jasmine has a clear fragrance, and the tea is mellow and refreshing, rich and pleasant. For high-grade scented tea, cover the cup with transparent glass, take 3g of scented tea, put it into the cup, brew it with boiling water slightly cooled to about 90℃, and then cover the cup to prevent the fragrance from losing. After two or three minutes, you can have a drink and feel fragrant and refreshing.
◆ Drink green tea in summer.
Summer is hot, the sun is like fire, people sweat in it, their physical strength is very high, and their mood is low. At this time, it is better to taste green tea. Because green tea belongs to unfermented tea, it is cold in nature, "cold can clear away heat", which can remove fire, promote fluid production to quench thirst, promote digestion and eliminate phlegm, and accelerate the healing of oral cavity and mild gastric ulcer.
But also has high nutritional components and medicinal values of reducing blood fat and preventing arteriosclerosis. This kind of tea has clear water color, elegant fragrance and fresh taste after brewing. It can be drunk every day in summer to clear away heat and relieve summer heat, strengthen the body and benefit the body. Among the treasures of green tea, there is Longjing in Shifeng, Hangzhou, Zhejiang Province, which is known as "the top green tea in China" because of its green soup and pleasant fragrance. Taihu Lake in Jiangsu Province is "Biluochun", with green tea color and rich aroma. Mao Feng, Huangshan, Anhui, is full of tea fragrance.

They can be brewed with boiling water at 80℃, and there is no need to cover the cup when brewing, so as to avoid being sulked by heat and affecting the freshness of tea soup.
◆ Drink green tea in autumn.
In autumn, the sky is high and the clouds are light, the golden wind is bleak, the flowers and trees are withered, and the climate is dry, which makes people thirsty and chapped. Traditional Chinese medicine calls it "autumn dryness", so it's time to drink green tea. Green tea, also known as oolong tea, belongs to semi-fermented tea, which is between green tea and black tea. The colors are blue and brown. After brewing, you can see that the middle of the leaves is blue and the edges are red. It is called "the edge of green leaves". It has both the fragrance and natural floral fragrance of green tea and the mellow fragrance of black tea. Not cold or hot, mild. It has the effects of moistening skin, moistening throat, promoting fluid production, eliminating accumulated heat in the body, and adapting the body to changes in natural environment.
Common oolong tea brands are Fujian Oolong, Guangdong Oolong and Taiwan Province Oolong, among which Tieguanyin in Anxi, South Fujian and Wuyi Rock Tea in North Fujian are famous. However, many oolong teas are divided into tea varieties, such as Dahongpao, Narcissus, Cinnamon, Tieguanyin, Lan Qi, Meizhan, Narcissus, Peach Blossom and Hairy Crab. Oolong tea is used to strong drinking, paying attention to taste and smell. Brewing oolong tea requires 100℃ boiling water. After soaking, pour the tea in the teapot into the teacup for a while, which is rich in flavor and fragrant in teeth and cheeks.
◆ Drink black tea in winter.
It is freezing in winter, everything is dormant, cold evil attacks people, the physiological function of human body declines, and the yang gradually declines. Chinese medicine believes: "In the cold winter, everything is alive and hidden, and the physiological activities of the human body are in a state of inhibition. The way to keep healthy is to keep out the cold, so black tea is the top grade in winter.
Famous traditional Kung Fu black tea products include Hong Hu, Hongyi, Ninghong, Hong Min, Taihong, Qi Hong, etc. It is famous for Qi Hong in Qimen County, Anhui Province. When brewing black tea, it is advisable to brew it with freshly boiled water and cover the cup to avoid fragrance. British people generally have the habit of drinking "afternoon tea". They often mix Qi Hong and Indian black tea, and then add milk and sugar to drink. In some parts of China, there is also the habit of drinking black tea with sugar, milk and sesame seeds. This kind of tea can not only warm the abdomen, but also increase nutrition and strengthen the body. Discrimination of new tea
New tea is better than old tea, which means ordinary, not necessarily. Timely storage, for Longjing tea, not only has good color and taste, but also has the beauty of fragrance. Another example is oolong tea. As long as it is properly preserved, even the tea aged every other year has the characteristics of rich aroma and mellow taste. However, among many tea varieties, for more teas, it is still "new and more expensive". Judging new tea and old tea can be distinguished from the following three aspects:
1. According to the color of tea, old tea and new tea can be distinguished. Generally speaking, the color of green tea is green, and the color of soup is yellow-green and bright; Black tea is a symbol of new tea. It is dark in color and bright red and orange in soup.
2. New tea and old tea can be distinguished by aroma. With the extension of time, the aroma of tea will change from high to low, and the aroma type will also change from new tea aroma to low stuffy aroma.
3. You can also distinguish new tea from old tea by its taste. No matter what kind of tea it is, the taste of new tea is mellow and fresh, while that of old Chaze is faint and unpleasant.
Tea quality identification
Generally speaking, the quality of tea can be identified by sensory evaluation. It is through people's vision, senses and taste organs that the intrinsic characteristics of tea are grasped, and the quality of tea is finally judged comprehensively through the methods of seeing, smelling, touching and tasting. Usually, first pick up a handful of dry tea with both hands, put it on your nose and take a deep breath of tea. Everything that smells like tea is good tea; Poor with green smell or mixed with other smells. At the same time, it can also be identified by combining the color of tea; Grab a handful of tea leaves by hand and put them in the middle of a white paper or a white plate. Spread out the tea leaves and observe them carefully. If green tea is dark green, black tea is dark green and oolong tea is dark green, and the color of each tea is basically the same, it is good tea. If the color of tea leaves is messy, uncoordinated or inconsistent with the real color of tea leaves, the quality is poor.
