How did people discover that tea can be drunk, and who can t drink tea?

There is a long record of tea drinking in Chinese history, and it is impossible to find out exactly what age it was, but there is a theory about the approximate era. And evidence can also be found that the habit of drinking tea in many parts of the world was indeed transmitted from China. Therefore, many people think that tea drinking was pioneered by the Chinese, and the tea drinking habits and tea planting habits in other parts of the world are directly or indirectly transmitted from China.

But there are also people who can find evidence that the habit of drinking tea was not only invented by Chinese, but also invented in some other parts of the world, such as India and Africa. In 1823, a major of the British invading army discovered a large tea tree in the wild in India, and some people began to believe that the birthplace of tea was in India, or at least in India. Of course, there are also records of wild tea trees in China, all of which are concentrated in the southwest region, and the records also include individual areas of Gansu and Hunan.

Tea tree is a very old dicot plant that is closely related to people's lives.

In China, there is also a debate about the earliest origin of the tea plant, and there are several theories. Nowadays, many people believe that in Yunnan, a scholar asserts that Xishuangbanna in Yunnan is the origin of tea trees after careful research and research. The earliest written record of the artificial cultivation of tea trees began with Mengshan tea in the Western Han Dynasty.

This is contained in the "Sichuan Tongzhi".

Legend has it that in ancient times, when Shennong was boiling water, a few leaves floated into the water because the water was too hot to take out, but after a while, he found that the water exuded a special fragrance, so he couldn't help but drink it, and he screamed hotly, but he found that the water was delicious after the leaves entered.

Ever heard the story of tomatoes!

It's the same, when people encounter unfamiliar things, many people don't dare to try, but some people are not afraid of death to know what new things are, so they slowly know the value of those things!

Of course, there are also people who have a coincidence, for example, when they are in a desperate situation and have nothing to eat, in a state of extreme hunger, they will be hungry, so they will meet good luck and meet new things!

Unawares! Many things are like this.

1. Patients with constipation: the polyphenols in tea have a certain astringent effect on the gastrointestinal mucosa, which can lead to aggravation of constipation;

2. Patients with neurasthenia or insomnia should not drink tea: The caffeine in tea has an obvious excitatory effect on the cerebral cortex, so if such patients drink tea, the brain will be in an extremely excited state and unable to rest;

3. People with iron deficiency anemia should not drink tea: The tannic acid in tea will cause the iron in food to form a precipitate that is not absorbed by the human body, aggravating anemia;

4. People with calcium deficiency or fractures should not drink tea: The alkaloids in tea will inhibit the absorption of calcium in the duodenum, and can also lead to calcium deficiency and osteoporosis;

5. People with ulcer disease should not drink tea: theophylline in tea will reduce the activity of phosphodiesterase, so that the gastric parietal cells secrete a large amount of gastric acid, and excessive gastric acid will inevitably affect the healing of the ulcer surface;

6. People with urinary stones should not drink tea: tea contains more oxalic acid, and drinking tea will aggravate the development of stones.

Lu Yu said in the "Book of Tea": "Tea is drinking, and it comes from Shennong's." ”

Legend has it that in the Shennong era more than 2,700 years ago, Shennong was excavated to help all sentient beings, taste herbs, and make herbs. One day, Shennong tasted a blade of grass that made his mouth dry and his head dizzy. Suddenly, a gust of wind passed, came a fresh aroma, looked up, only to see the green leaves and green onions on the tree, Shennong picked a piece and put it in the mouth to chew carefully, the taste was bitter at first, and then the fragrance was sweet, after eating, the smell was more swift and fragrant, the bottom of the tongue was relished, the spirit was refreshing, the dizziness was reduced, and the dry mouth gradually disappeared.

The day of the name of Shennong is "Tu", which is the earliest legend of tea.

Brewed tea is edible, and the reasons are as follows.

From the earliest tea drinking tea and chewing tea can detoxify and the great leader *** tea drinking always eat up the tea residue (also called the bottom of the leaf) can be understood from the side of the tea can be eaten, and the brewed tea can also be eaten, according to scientific research found that there are some insoluble vitamins in tea, that is, fat-soluble vitamins, etc., plus vitamins A, D, K, B can only be soaked in a small amount of dissolved in the tea soup, so the brewed tea has nutritional value. In this way, it is possible to understand that tea can be eaten, because the tea soup mainly contains tea polyphenols, caffeine, etc., and a large number of nutrients exist in the tea residue, so the brewed tea can be eaten. In addition, tea was first eaten directly for medicinal purposes, and now there are some ethnic minorities who eat tea as cold dishes, and Hangzhou also has the famous Longjing shrimp and Longjing scrambled eggs.

Precautions: Section.

Brewed tea leaves can be eaten, but not too much. Tea has the effect of refreshing the mind, quenching thirst, and diuretic, and can reduce lipids**, anti-fatigue, anti-radiation, protect teeth, and is a product for both medicine and food.

Therefore, moderate consumption of tea can better exert the nutritional value of tea and have certain benefits to the human body.

3a An accidental invention.

Did you know that the most popular drink in the world (second only to water) was invented by chance? Many believe that tea was first drunk about 5,000 years ago. It is said that a Chinese ruler named Shennong was the first to discover tea as a drink.

One day, Shennong was boiling drinking water on a bonfire. Some of the leaves fall from the tea tree into this water and stay in it for a while. It emitted a fragrance, so he tasted the brown water.

It was delicious, and one of the most popular drinks in the world was born.

Thousands of years later, the "Tea Saint" Lu Yu mentioned Shennong in his book "The Book of Tea". This book describes how tea plants are cultivated and used to make tea leaves. It also discusses what kind of water is used to make tea where the best tea leaves are produced.

It is believed that tea was brought to Korea and Japan during the 6th and 7th centuries. In England, it is known that tea sila did not appear until about 1660, but in less than 100 years, it became a national drink. Tea from China to Western countries** appeared in the 19th century.

Enlightenment and the Qin and Han dynasties began to enter the mode of tea tasting. In the Han Dynasty, it began to enter the commercialization and also began to enter the production stage.

In the Tang Dynasty, with the blessing of Lu Yu's tea scriptures, the leaf industry began to develop gradually.
