The black tea is rich in nutrients, the most important are Vitamins and minerals, in addition to proteins, amino acids, sugar substances and so on.

2. Help digestion, digestion of grease, smooth stomach

Black tea contains a large number of caffeine, vitamins, amino acids and other effective components of the human body digestion has a certain role in regulating the metabolism of fat, but also caffeine stimulation to enhance the gastric secretion of gastric juices, which can improve appetite, help digestion.

3. Lowering fat, weight loss, soften human blood vessels, prevention of cardiovascular disease

The rich content of tea polysaccharide in black tea has the effect of lowering blood lipids and peroxide activity in the blood.

4. Antioxidant, delay aging, prolong life

Black tea in the catechins, theaflavin, theanine and tea polysaccharides, especially the content of more complex flavonoids, etc. have the function of scavenging free radicals, and thus the effects of black tea has the effect of antioxidant, delaying the role of cellular aging.

5. Anti-cancer, anti-mutagenesis

Black tea contains special ingredients that have a certain effect on anti-tumor, therefore, regular consumption of black tea can be anti-cancer, anti-mutagenesis.

6. Lower blood pressure

Tea has been reported to lower blood pressure. Recently, Japan reported that the amino acid theanine, which is unique to tea, can inhibit the rise in blood pressure by activating dopaminergic neurons.

7. Improve sugar metabolism, lowering blood sugar, prevention and treatment of diabetes

Tea polysaccharide complex in black tea is the main component of hypoglycemia. Tea polysaccharide complexes, often called tea polysaccharides, are a class of complex and highly variable mixtures.

8. Sterilization, anti-inflammatory

The main components of black tea soup color are theaflavin and thearubigin. Studies have shown that theaflavin is not only an effective free radical scavenger and antioxidant, but also has a significant antibacterial effect on Clostridium botulinum, Enterobacteriaceae, Staphylococcus aureus, Podococcus, Bacillus cereus.

9. Diuretic detoxification, reduce the toxicity of alcohol and tobacco

The caffeine in black tea has a diuretic function, and caffeine has a certain stimulating effect on the bladder, so that it can both assist in diuresis, but also can help to wake up and lift the poison of alcohol.

The effects of black tea 2

The effects of black tea 1:

Black tea has thirst quenching, anti-radiation, anti-cancer, anti-cancer, help sober up, promote digestion, weight loss, delay aging, lower cholesterol and other effects. It can enhance the acuity of the central nervous activity of the brain, improve thinking ability, lower blood pressure, inhibit atherosclerosis and so on.

Tea belongs to the post-fermented tea, its unique processing, especially the participation of microorganisms so that it has a special Chinese medicine efficacy, which is rich in tea polysaccharide compounds by the medical profession that can regulate the body's glucose metabolism (to prevent diabetes), lowering blood lipids, blood pressure, anti-coagulant, thrombosis, and improve the immunity of the body. Clinical trials have proved that the special effects of black tea are significant and irreplaceable by other teas. Through the use of high-throughput screening technology, 10 modern disease models were selected to study the function of black tea on human health, including models for lowering blood pressure, blood lipids and blood sugar, models for inhibiting the proliferation of cancer cells, models for improving human immunity, etc. The evaluation of the models revealed that the black tea has a significant effect on human health. Evaluation of the models revealed that Qianliang tea and Poria tea have significant effects on lowering blood pressure, lipids and glucose, and are very helpful for human fat metabolism and weight control. In addition, the extract of Qianliang tea has inhibited the spread of stomach cancer cells and liver cancer cells. History over the centuries has proved that it is the drink of life for the herdsmen in the border areas, "It is better to have no food for three days than no tea for one day", which is a testimony to the unique pharmacological efficacy of black tea. Now with the change of people's life style and diet structure, fat drinking milk more and more, drinking black tea is more and more necessary. Because Poria tea has a unique hair flower process, producing a kind of coronary cysts, in the fermentation process to produce a Pernod component, oxidizing the body's excess cholesterol, to prevent the accumulation of fat, the world's first-class microbiologist Dr. Wang Zhiwei, in Japan to study microorganisms and food fermentation up to 18 years, said Poria tea is the world's most miraculous food.

Effects of black tea 2:

Aged black tea in the process of storage, microbial reproduction and metabolism through the generations, resulting in a series of small molecules of unrecognized active substances, that is, secondary metabolites, the formation of these substances is slow, and the chemical nature of the chemical nature of the unstable, only to maintain in the original natural condition of the human body to produce special effects, it is the same as the thousand-year-old Ganoderma lucidum. It has the same effect as the thousand-year-old Lingzhi in terms of efficacy. Anhua people mostly have this experience, drinking aged black tea for gastrointestinal disease effect can be said to be "medicine to disease".

The main component of black tea soup color is the theaflavin and thearubigin, research results show that theaflavin is not only an effective scavenger of free radicals and antioxidants, but also anti-cancer, anti-mutagenic, anti-bacterial and anti-viral, to improve and treat cardio-cerebral vascular disease, the treatment of diabetes and other physiological functions.

The main functional component of black tea is tea complex polysaccharide compounds, which are considered by the medical profession to regulate glucose metabolism in the body (to combat diabetes), reduce blood lipids and blood pressure, anti-coagulation, thrombosis, and improve the body's immune system. Clinical trials have proved that these special features of black tea are significant and irreplaceable by other teas. Black tea can inhibit the accumulation of belly fat. When it comes to obesity, people will immediately think of abdominal fat first, and black tea has a significant effect on the increase of fat that has been vice.

Black tea is also a decaffeinated health drink (high maturity of raw materials, roasting and other factors), compared with cola and other teas, black tea does not affect sleep, you can drink a day to night, insist on drinking every day the effect is very good.

The effects and role of black tea 3

The main varieties of black tea in Hunan, Hubei flat tea, Sichuan border tea, Guangxi six Fort loose tea, Yunnan Pu'er tea. One of the Yunnan Pu'er tea ancient and modern reputation, is the hair effect of tea, belonging to the alkaline class, can be put for decades, the longer the time to put the more valuable! Taste of course very good la, because it belongs to the black tea class, no green tea bitter, as intestinal elimination fat scraping oil water okay, used to lose weight will not have a great role, but also has a cosmetic, treatment of skin diseases (can prevent melanin precipitation on the skin), refreshing, promote digestion, treatment of dysentery, sobering up, improve immunity, lowering blood lipids.

Black tea cleansing diuretic, its representative for: Pu'er, the old six An, according to the nature of the characteristics of the warm, benefits: clear kidney fire, fat and stagnation, for example, when you eat a lot of moon cakes, 'when to come to stagnation to fat is more than appropriate, young and old. Suitable water temperature: 100 degrees Celsius brewing.

Black tea contains a variety of effective ingredients conducive to human health, the people of Northwest China have "rather have three days without food, not a day without tea," said the tea is black tea. We also made a field survey, herders reflect, a day without drinking black tea stomach bloating, three days without drinking black tea people weak, like a disease. Herdsmen to cook the dregs of tea to the horse to eat, the horse should be much more spiritual. We also note that such a phenomenon, some nomadic herdsmen grazing grass by grass and live throughout the winter, there is no vegetables and fruits, the human body needs plant-based vitamins taken entirely from tea, a winter down, people are also healthy, but also from another aspect of the proof of black tea on the human body's health effects.

1, lipid reduction and weight loss

Obesity is a series of eating regulation and energy metabolism disorders caused by specific biochemical factors, a series of diseases triggered by obesity, has become a major killer of human health.

The tea polyphenols and their oxidation products in black tea can dissolve fat and promote the discharge of lipids, thus reducing the total cholesterol, free cholesterol, LDL cholesterol, and triglyceride content in the blood, thereby reducing the cholesterol deposition on the arterial blood vessel wall and lowering the incidence of arterialization. It can also activate protein kinase, accelerate lipolysis and reduce the fat content in the body. Scientists through the human body test found that, compared with people who drink ordinary water, drinking tea daily energy consumption is higher than the average 67eal, fat oxidation rate is higher than 12%. This proves that black tea does have a fat-lowering and weight-loss effect.

2, enhance gastrointestinal function, improve immunity

Black tea active ingredients in the human stomach and intestines to inhibit the growth of harmful microorganisms at the same time, but also to promote the growth and reproduction of beneficial bacteria (such as lactobacilli), has a good adjustment of gastrointestinal function of the role of the alkaloids can promote gastric secretion, flavanols can be a significant enhancement of Its alkaloids can promote the secretion of gastric juice, and flavanols can significantly enhance peristalsis. Research also found that the black tea in the catechin compounds and tea saponins on oral bacteria, Helicobacter, Escherichia coli, typhoid fever and paratyphoid bacteria, staphylococcus bacteria and many other pathogenic bacteria growth has a killing and inhibiting effect, and thus has a significant elimination of stagnation and bloating, stopping the leakage, eliminating the role of constipation, the white-collar workers often sit down and work, has an important role, but also the folk stop leakage of the good medicine.

The theanine in black tea has a good function of enhancing human immunity.

3, anti-aging, regulate the role of the brain nerve

The natural aging of the human body and including tumors, cardiovascular and other degenerative diseases, there is a *** with the process of the development of the cells by the oxidative damage caused by oxygen free radicals. More than 95% of the body's free radicals for oxygen free radicals, oxygen free radicals are damage to biological macromolecules, involved in the occurrence and development of a variety of diseases and the basis of aging. Under normal circumstances, free radicals in the human body are constantly generated and removed, in a state of balance. However, in some cases, free radicals are generated and removed out of balance, causing protein denaturation, reduced enzyme activity and other hazards, thus leading to various diseases and accelerated aging. The catechins and complex flavonoids in black tea have very active hydroxyl hydrogens, which can provide a large number of hydrogen protons to react with free radicals and remove excess free radicals, thus protecting the human body from longevity.

4, lower blood pressure, lower blood sugar

Theanine in black tea can play a role in inhibiting the rise in blood pressure, while alkaloids and flavonoids have the ability to make the blood vessel wall relaxation, increase the effective diameter of the blood vessels, and by making blood vessels diastolic and blood pressure down. Diabetes is one of the modern health killers of middle-aged and elderly people, and, with the improvement of people's living standards and the aging of the population, the incidence of diabetes is gradually increasing. So far, diabetes is still a disease that cannot be cured, and it is mainly controlled by drugs and dietary regulation. Some studies have proved that the tea polysaccharide in tea has obvious effect on lowering blood sugar, and its effect is similar to insulin. To mice injected with tea polysaccharide 7 hours later, its blood sugar decreased by 70%. Black tea contains more tea polysaccharide, is the ideal drink for the prevention and treatment of diabetes, folk tea is also used in the treatment of mild diabetes custom, and is the more coarse tea the better. Black tea also has anti-cancer, blood fat, radiation, anti-inflammatory, and other tea **** sexual health effects.
