The benefits of tea

The earliest discovery and utilization of tea began with medicinal use. "Shennong tastes a hundred herbs and encounters seventy-two poisons every day. He made tea and solved it. " Tea in Britain is: the liquid of health, the drink of the soul. Known as China's "national wine". A large number of studies in modern science have confirmed that tea does contain biochemical components closely related to human health. Tea not only has the pharmacological effects of refreshing brain, clearing away heat and relieving summer heat, resolving food stagnation, relieving fatigue and losing weight, clearing away heart fire and vexation, relieving hangover, promoting fluid production to quench thirst, reducing fire and improving eyesight, stopping dysentery and removing dampness, but also has certain pharmacological effects on modern diseases such as radiation sickness, cardiovascular and cerebrovascular diseases and cancer. It can be seen that the pharmacological effects of tea are numerous and extensive, which cannot be replaced by other drinks.

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.

In addition, it should be noted that tea is an irritating drink, containing tannic acid and caffeine, and teenagers should not drink tea. And girls should never drink tea in six stages:

1, when menstruation comes

2. The pregnant woman is pregnant.

3. Before a pregnant woman is about to give birth

4. Mothers who want to breastfeed themselves after giving birth.

Step 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.

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 and fragrance complement each other", which is made by mixing tea and flowers by using the principle of smell absorption characteristics of tea such as fried green tea and fragrance emission 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.

◆ Drink green tea in summer.

Summer is hot, the sun is like fire, people sweat like rain 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.

◆ 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".

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. Black tea is sweet and warm, which can nourish human yang; Black tea is rich in protein and sugar, which can warm the abdomen by heating, enhance the cold resistance of human body, and help digestion and greasy. Black tea is also called fully fermented tea because it is fully fermented during processing and oxidizes tea tannins. Fresh tea leaves are oxidized to form red oxidative polymerization products-theaflavins, thearubigins and theabrownins. Some of these pigments are dissolved in water and brewed into black tea soup. 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, which can not only warm the abdomen, but also increase nutrition and keep fit.

shopping guide

It is not easy to buy tea. If you want to get good tea, you need to master a lot of knowledge, such as the grade standard, price, market, evaluation and inspection methods of various teas. The quality of tea is mainly identified from four aspects: color, fragrance, taste and shape, but for ordinary tea drinkers, when buying tea, they can only look at the shape and color of dry tea and smell the fragrance of dry tea, which increases the difficulty of judging the quality of tea. Here is a rough introduction to the method of identifying dry tea. The appearance of dry tea is mainly seen from five aspects, namely tenderness, rope, color, broken and clean.

Gentle:

Generally, tea with good tenderness meets the appearance requirements ("smooth, flat, flat and straight"). But tenderness can't be judged only by the number of fine hairs, because the specific requirements of various teas are different. For example, the high-quality Lion Peak Longjing is fluff-free. The tenderness of bud leaves is judged by fluff, which is only applicable to "fluff" teas such as Mao Feng, Maojian and Yinzhen. What needs to be mentioned here is that the most tender fresh leaves should also sprout, and it is not appropriate to pick the bud heart unilaterally. Because the bud nucleus is an imperfect part, its content is not comprehensive, especially the chlorophyll content is very low. Therefore, tea should not only be made into buds in pursuit of tenderness.

Cable:

Cord is a certain shape and specification of various tea sets, such as fried green strips, round pearl tea, flat longjing tea, granular red broken tea and so on. Generally, long strip tea is elastic, straight, strong, thin, round, flat, light and heavy; Round tea depends on the elasticity, uniformity, weight and ethereal degree of particles; Flat tea to see if it is smooth and meets the specifications. Generally speaking, the rope is tight, heavy, round (except flat tea) and straight, indicating that the raw materials are tender, the workmanship is good and the quality is excellent; If the appearance is loose, flat (except flat tea), broken, smoky and burnt, it means that the raw materials are old, the workmanship is poor and the quality is poor. Take the standard of Hangzhou green tea as an example: Grade I, Grade II, Grade III, Grade IV, Grade V, Grade VI, fine grain, fine grain, compact grain, compact grain and slightly loose grain.

Color:

Tea color is closely related to the tenderness of raw materials and processing technology. All kinds of tea have certain color requirements, such as black tea, green tea, oolong tea and black tea. However, no matter what kind of tea, good tea requires consistent color, bright luster, oily and fresh. If the colors are different, the shades are different and dull, it means that the raw materials are old and tender, the workmanship is poor and the quality is poor. The color of tea also has a great relationship with the origin and season of tea trees. Such as alpine green tea, the color is green and yellowish, fresh and bright; Low camellia or flat tea is dark green and shiny. In the process of making tea, due to improper technology, the color often deteriorates. When buying tea, you should judge according to the specific tea you buy.

Crushing:

The whole crushing is the shape and degree of tea crushing, with uniformity being the best, followed by crushing. The standard tea tasting is to put the tea in a plate (usually made of wood), so that the tea can be layered in turn according to its shape, size, weight, thickness and crushing degree under the action of rotating force. Among them, the thick ones are at the top, the tight ones are concentrated in the middle, and the broken ones are deposited at the bottom. All kinds of tea, medium-grade tea is the best. The upper layer is generally thick and old leaves, with light taste and light water color; There are many broken teas at the lower level, and the taste is often too strong after brewing, and the soup is darker.

Clarity:

Mainly depends on whether tea is mixed with camellia oleifera. , tea stalks, tea powder, tea seeds and the amount of inclusions such as bamboo chips, sawdust, lime and sediment mixed in the production process. Tea with good purity does not contain any inclusions. In addition, it can also be identified by the dry aroma of tea. No matter what kind of tea, there must be no peculiar smell. Every kind of tea has a specific aroma, and the dry aroma and wet aroma are also different, depending on the specific situation. Green gas, burnt smoke and cooked stuffy smell are not desirable. It is the taste, aroma and color of the brewed tea soup that is the easiest to judge the quality of tea. So if you can, try making tea.

Generally speaking, locally produced tea is pure, but the quality of tea is different due to the difference of tea making technology. New tea is not as new as possible, and improper drinking can easily hurt the stomach. Because the fresh tea has just been picked and stored for a short time, it contains more unoxidized polyphenols, aldehydes and alcohols, which have little effect on healthy people. However, 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.
