As the old saying goes, Shennong tasted a hundred herbs and encountered 72 poisons every day, and used tea to relieve his worries. Tea is tea. This shows that the ancients in our country noticed the health care function of tea very early, and at present, all kinds of tea products are dazzling. Today, let's simply comb the tea products.

Tea has two meanings, one is related to plant tea, and the other is the tea we usually drink or the water boiled by medicinal materials. So we usually drink tea, which can refer to tea or Chinese herbal medicine water, while Chaze can refer to tea or Chinese herbal medicine. Usually we don't distinguish the two in our daily life, but they do have obvious differences, so tea and tea substitutes are used to distinguish the two at present. Tea only refers to drinks brewed or boiled with tea, which will be introduced in detail later. Tea substitute refers to drinks brewed with Chinese herbal medicine or boiled water. Our common tea substitutes include barley tea for clearing away heat and fire, hawthorn for reducing weight and fat, American ginseng for invigorating qi, roses for soothing the liver and relieving depression, roses and so on. These all-purpose teas will be sold in bulk or in packages in supermarkets. In addition, strictly speaking, herbal teas such as Heqizheng and Wang Laoji also belong to tea substitute.
Basic tea, processed tea, tea products
There are also many subdivided products of tea. It is divided into basic tea, reprocessed tea and tea products. Basic tea is the common green tea, black tea and so on in our life, which will be explained in detail later. The reprocessed tea is mainly scented tea. Scented tea is made from basic tea and different kinds of flowers. The most common scented tea is jasmine tea (the mixture of jasmine and green tea is shown below), and there are also some tortoiseshell teas and so on. These scented teas not only have the taste of tea itself, but also have a strong floral fragrance, which is intoxicating.
Six basic teas
China has a vast territory and rich resources, and the types of tea are also very colorful. According to the processing technology of tea, we divide these teas into six basic teas: green, red, cyan, black, yellow and white. Among them, green tea has the most varieties and the widest output, followed by black tea and oolong tea, and other types have the least output. The main difference between the processing techniques of these teas lies in the degree of fermentation. Here is a brief introduction.
Green tea. No fermented tea, cool. Famous green teas include West Lake Longjing, Biluochun, Xinyang Maojian Tea and Luan Guapian. In addition, there are many special green teas in various places (such as the guns in Yucheng Banner below), all of which have unique taste characteristics and may not be lost to these famous teas. Most green teas taste fresh and light. ? PS: A famous tea called Anji White Tea is actually a kind of green tea.
Black tea. Fermented tea is mild. The famous black teas in China are Qimen Black Tea and Dianhong. Most of the tea produced abroad is processed into black tea. Qi Hong, Sri Lankan black tea and Indian Darjeeling black tea are called the three most fragrant teas in the world, because black tea is mainly drunk abroad and its aroma is high.
Green tea. Oolong tea, also known as oolong tea, is a semi-fermented tea with a flat nature. The most famous are Anxi Tieguanyin and Dahongpao. These teas are the main raw materials of Kung Fu tea in Guangdong, Fujian and other places, and there is a saying that seven teas are fragrant.
Black tea. Fermented tea is mild. The most famous black tea is Pu 'er tea, in addition to Anhua black tea and so on. Pu 'er tea is mainly produced in Yunnan, which can be divided into raw tea and cooked tea, and there are many cakes and some loose leaves.
Yellow tea. Micro-fermented tea is rare. The main varieties are: Junshan Yinzhen, Mengding Huangya, Huoshan Huangya and Pingyang Tanghuang.
White tea. Micro-fermented tea has few varieties and low yield. Mainly produced in Fujian, there are mainly varieties such as Baihao Yinzhen.
Tea is more about warmth, cold and coolness, and rarely about five flavors and meridian tropism. Perhaps the difference between several teas is mainly in sex, not in taste and meridian tropism.
Tea in China is mainly divided into six categories: green tea, yellow tea, white tea, green tea, black tea and black tea. These six categories are classified according to the degree of tea fermentation, and the taste of the six categories of tea is also determined by the degree of fermentation. Generally speaking, green tea, yellow tea and white tea have low degree of fermentation and belong to herbal tea; Green tea is semi-fermented and belongs to neutral tea; Black tea and Pu 'er tea are fermented and belong to warm tea.
Therefore, people with cold body or winter should drink black tea and black tea; People who are hot should match green tea, yellow tea and white tea in summer; Peace-loving people should drink green tea in winter
There are few records about the sexual orientation of tea in the literature. At present, only the sexual taste of China herbal tea (green tea) has been found, but the sexual taste of other teas has not been found.

The main components of tea: tea polyphenols, caffeine (theophylline) and theanine, which correspond to antioxidant, refreshing and delicious effects respectively. The lower the degree of fermentation, the more tea polyphenols and the stronger the antioxidant capacity. With the increase of fermentation degree, the caffeine content will increase relatively (a little forgotten, to be verified).
The function of caffeine (theophylline) is refreshing, and everyone is familiar with it.
Tea polyphenols are the main components of tea antioxidants, and also the main active substances for radiation protection, blood lipid reduction and free radical scavenging.
Theanine provides the umami taste of tea, so generally only tender green tea (before tomorrow and before rain) pays attention to umami taste. For black tea, black tea and other old teas, the bitter taste will be heavier because of the rising content of theophylline and other substances.
Besides the basic tea mentioned above, there are also some tea products. The most common is milk tea-a mixture of black tea and milk. Of course, there are many other drinks derived from it, such as milk green (green tea with milk) and so on. In addition, there are some cakes processed with tea powder or matcha as raw materials.
Most teas have many functions, such as refreshing, anti-aging and anti-radiation. In addition, some tea substitutes made of Chinese herbal medicines have many additional functions, forming a good habit of drinking tea and enjoying a better life.
