Where can I buy "China Tea" brand high-grade Fuzhuan brick tea and thousand taels of tea leaves in Xi 'an, Shaanxi?

I couldn't drink high-grade before, and it was rarely found in Xi' an, Shaanxi.

Recently, there is one on the second floor of Xi 'an Tea Wholesale Market (diagonally opposite to light industry), which makes "China Tea" Hunan black tea. There are thousands of tea leaves, top-grade Fuzhuan tea, top-grade Tianjian tea and top-grade black brick tea. I feel that the variety is quite rich.

In fact, the function of Hunan black tea is quite good, which is different from other teas:

Main health components of black tea

1. Tea polysaccharide has the highest content and the strongest activity in dark tea.

According to the determination, the content of tea polysaccharide increases with the aging of tea raw materials. The content of tea polysaccharide in grade six tea is about twice that of grade one tea. In addition, the content of tea polysaccharide in different tea leaves varies with different processing methods. Fresh leaves with the same tenderness are processed into black tea, green tea and black tea respectively, and the content of tea polysaccharide in black tea is the most (in contrast, the tea polysaccharide in Hunan black tea is higher than that in Yunnan Pu 'er).

Tea polysaccharide has multiple pharmacological effects: ① lowering blood sugar; ② Hypolipidemic effect and anti-atherosclerosis effect; ③ Anticoagulant and antithrombotic effects; ④ Enhance immunity; ⑤ Radiation protection, hypoxia tolerance and increased coronary blood flow.

2. Special amino acid (γ-aminobutyric acid)

Studies have shown that γ -aminobutyric acid can significantly lower blood pressure, improve cerebral blood circulation, increase oxygen supply and improve brain cell function. It is reported that γ -aminobutyric acid has the functions of improving vision, lowering cholesterol, regulating hormone secretion, relieving ammonia poisoning, improving liver function, activating renal function and improving climacteric syndrome.

3. Tea pigment

The main components of dark tea soup color are theaflavins and thearubigins, which are the products of oxidative condensation of tea polyphenols and microorganisms, and are also one of the main physiological active substances of tea.

The results show that theaflavin is not only an effective free radical scavenger and antioxidant, but also has obvious lipid-lowering effect. In addition, it also has the functions of anti-cancer, anti-hypertension, anti-mutation, anti-bacteria, anti-virus, improving and treating cardiovascular and cerebrovascular diseases, and treating diabetes. Tea polyphenols can inhibit the invasion of influenza virus to some extent. It is also found that theaflavins can inhibit the infection of rotavirus and enterovirus, and also have certain effects on bovine virus and coronavirus.

4. Mineral elements

The mineral elements in tea are mainly concentrated in mature leaves, stems and stems. The raw materials of black tea are relatively mature, rich in mineral elements such as selenium, zinc, fluorine and calcium. The fluorine content in tea plants is the highest among all plants, mainly accumulated in the leaves of tea plants, and the fluorine content in old leaves is higher. Drinking black tea regularly has obvious effect on preventing dental caries and osteoporosis in the elderly.

Selenium is an essential component of human glutathione oxidase (GSH-PX), which can stimulate the production of immune proteins and antibodies, enhance human resistance to diseases, and play a significant role in treating coronary heart disease and inhibiting the generation and development of cancer cells. Selenium in tea is also mainly concentrated in mature leaves. The soil in Wuling Mountain is rich in selenium, and the black tea produced is a typical natural selenium-enriched tea. The selenium content in tea can be as high as 3.6-6.4㎎/㎏ (generally lower than 0. 16㎎/㎏).

5. Tea saponin

Tea saponin is widely distributed in all parts of tea trees, most of which are roots of old leaves. Tea saponin has the functions of hemolysis, cholesterol reduction, antifertility, antibacterial, snail control, anticoagulation, sedation, anticancer and blood pressure reduction.
