9 Effects and Functions of Chinese Black Tea

Nine Effects and Functions of Chinese Black Tea

Black tea is a kind of fermented tea with many effects and functions. Including eliminating fat and losing weight, lowering fat and blood pressure, antioxidant and anti-aging, eliminating food and stomach, clearing heat and detoxification.

First, black tea has sterilization, anti-inflammatory effect

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 on Clostridium botulinum, intestinal bacillus, Staphylococcus aureus, Podocarpus, Bacillus cereus has obvious antibacterial effect. In addition, theaflavin has a certain inhibitory effect on influenza virus attack and rotavirus and enterovirus infection.

Second, black tea has blood pressure lowering effect

Tea has the effect of lowering blood pressure has long been reported. Recently, Japan reported that the amino acid theanine, which is unique to tea, can activate dopaminergic neurons and inhibit the rise in blood pressure. Here, it is also found that caffeine and catechins in tea can relax the blood vessel wall, increase the effective diameter of blood vessels, and reduce blood pressure through vasodilation. Our Lou Fuqing found that theophylline has significant anticoagulation, promote fibrinolysis, prevent platelet adhesion aggregation, inhibit the role of arterial smooth muscle cell proliferation, but also can significantly reduce the high-fat animal serum triglycerides, low-density lipoproteins, improve serum high-density lipoproteins, and ACE enzyme has a significant inhibitory effect, with antihypertensive effect.

Third, black tea has antioxidant, aging, longevity effects

Free radical theory of aging that, under normal physiological conditions, the free radicals in the human body continue to produce, but also continue to be cleared, in a state of balance. Black tea is not only rich in antioxidant substances such as catechins, theophylline, flavonoids, vitamin C, vitamin E, D-carotene, etc., but also contains a large number of antioxidant trace elements, such as zinc, manganese, copper (the constituent element of SOD) and selenium (the constituent element of GSHPX). Black tea in the catechins, theaflavins, theanine and tea polysaccharides, especially the content of more complex flavonoids have the function of scavenging free radicals, and thus has the role of antioxidant, slow cell aging.

Fourth, black tea helps digestion, digestion, smooth gastrointestinal efficacy

Caffeine, vitamins, amino acids, phospholipids, etc. in black tea can help human digestion and regulate fat metabolism, and the stimulating effect of caffeine can improve the secretion of gastric juice, thus enhancing appetite and helping digestion. Japanese scholars have proved through scientific testing, black tea has a strong anti-greasy, digestion and other functions, which is also the meat-eating peoples especially like the reason for this tea.

China's northwestern ethnic minority people's food structure is beef, mutton and cheese, so there is a “would rather three days without food, not a day without tea,” said, which can “go to fat and greasy tea,” “to solve the meat and fish “The efficacy of the tea has a lot to do.

In addition, black tea can also improve the intestinal microbial environment, with the function of smooth stomach. China's folk have used the old black tea for the treatment of bloating, dysentery, do not eliminate the tradition of food.

Fifth, black tea diuretic detoxification, reduce tobacco and alcohol poisoning

The diuretic function of caffeine in black tea is realized through the kidney to promote the filtration rate of water in urine. At the same time, caffeine stimulation of the bladder can assist both diuretic, but also help to wake up and release alcohol poisoning. At the same time, the tea polyphenols in black tea not only precipitate the nicotine of tobacco and excrete it with the urine, but also remove the free radicals in the smoke and reduce the toxic effects of smoke on the human body. For heavy metal poisons, tea polyphenols have a strong adsorption effect, and thus more tea can also alleviate the toxic effects of heavy metals.

Six, black tea can improve sugar metabolism, lower blood sugar, prevention and treatment of diabetes

Tea polysaccharide complex in black tea is the main component of hypoglycemia. Tea polysaccharide complex is usually called tea polysaccharide, is a class of complex composition and a mixture of large changes. The results of the determination of the tea polysaccharide content of several types of tea show that black tea has the highest content of tea polysaccharides, and its component activity is also stronger than other types of tea, this is because in the fermented tea, due to the role of glycosidases, proteases, hydrolytic enzymes, and the formation of a relatively short length of the sugar chain and peptide chain of the sake of the short peptide chain than the long peptide chain is easier to be absorbed and the biological activity of the stronger, which may be fermented tea, especially the black tea tea polysaccharides This may be one of the reasons that fermented tea, especially black tea polysaccharide, has better hypoglycemic effect than other teas.

Seven, black tea has anti-cancer, anti-mutagenic effect

Cancer is one of the diseases that cause high mortality rate in the world. Since the late 1970s, scientists around the world have found that tea or tea extracts have inhibitory effect on the occurrence of many types of cancer. Hunan Agricultural University used the modern drug screening of cutting-edge technology of high-throughput screening technology of black tea for tumor cell model SGC7901 high-throughput screening studies, proving that black tea has obvious inhibitory effect on tumor cells.

Eight, black tea can regulate blood lipids, blood sugar, blood pressure, to prevent vascular sclerosis

High blood lipid content will make lipid deposition on the blood vessel wall, thus causing atherosclerosis and thrombus formation. Black tea has a good degradation of fat, anticoagulation, promote the role of fibrinogen dissolution and significant inhibition of platelet aggregation, but also to make the vascular wall relaxation, increase the effective diameter of the blood vessels, thereby inhibiting the aorta and coronary arteries within the wall of atherosclerotic plaque formation. Achieve the purpose of lowering blood pressure, softening blood vessels, prevention and treatment of cardiovascular disease.

The rich content of tea polysaccharide in black tea has the effect of lowering blood lipids and blood peroxide activity. The General Hospital of the Chinese People's Liberation Army in May 1990 to May 1991 on a dry rest house 155 old cadres in 55 patients with high blood lipids, after taking black tea 180 days (3 grams per day) of the situation for observation, of which 50 cases of drinking black tea, blood lipid content and blood peroxide activity decreased significantly.

In Xinjiang, Inner Mongolia, Qinghai and other key consumption areas of Por Tea epidemiological investigations show that long-term consumption of black tea on the human body's blood lipids, blood sugar, blood pressure, vascular sclerosis has a good regulatory role, and weight, body shape has a good regulatory role.

Nine, black tea can supplement dietary nutrients

Black tea is rich in nutrients, most notably vitamins and minerals, in addition to proteins, amino acids, sugar substances. For the staple food of beef, lamb and cheese, dietary lack of vegetables and fruits in the Northwest Territories residents, long-term consumption of Hunan black tea, is an important source of essential minerals and vitamins for their bodies, there is a tea of life.
