Replenish diet nutrient
Dark Tea (Hei Cha) contains rich nutrients, most notably vitamins and minerals, plus protein, amino acids, sugar substances.
Help digestion, oily solution, make intestinal tract unhindered
Dark Tea (Hei Cha) rich in caffeine, vitamins, amino acids, phospholipids, etc. help body's digestion, regulate fat metabolism, caffeine stimulation,can also enhance the secretion of gastric juice volume, thus enhancing the appetite and help digestion
Lipid-lowering, weight loss, softening of human blood vessels, prevention of cardiovascular disease
Dark Tea (Hei Cha) can reduce blood fat and the role of peroxidase.
Anti-oxidation, anti-aging, longevity
Dark Tea (Hei Cha) is not only rich in antioxidant substances such as catechins, tea pigments, flavonoids, vitamin C, vitamin E, D a-carotene, etc., but also contains large amounts of trace elements which also have antioxidant effect such as zinc, manganese, Copper (SOD composition of elements) and selenium (GSHPX the composition of elements) and so on. Its catechins, theaflavins, theanine and tea polysaccharides, in particular the more complex content of flavonoids and so has the function of anti-oxidation, scavenging free radicals and delaying cell senescence.
The study made by Hunan Agricultural University on Dark Tea with a model of tumor cell SGC7901 adopting cutting-edge technology of High Throughput Screening has proven that Hei Cha has significant inhibiting effect on tumor cells.
It has long been reported that tea has a role of lowering blood pressure. Recently, the Japanese reported that theanine, an unique amino acid can activate dopaminergic neurons, playing an inhibitory role in blood pressure. In addition the catechins and caffeine in tea can relax blood vessel walls and increase the effective diameter of blood vessels, decreasing blood pressure through vasodilation.
To improve carbohydrate metabolism, lowering blood sugar, diabetes control
Tea polysaccharide complex in Dark Tea is the main component which lowers blood sugar. Tea polysaccharide complex commonly referred to as tea polysaccharide, is a complex which changes in mixture. Studies showed that Hei Cha has the highest content of tea polysaccharide compared to the other types of tea. Tea polysaccharide in dark tea is more active than that of any other kinds of teas. It is because sugar chain and peptide chain with relatively short length formed by glucosidase, protease, hydrolase in fermented tea is more easily absorbed and more active than that of longer length. That is why Hei Cha excels any other teas in lowering blood sugar.
Theaflavins and thearubigins are the major components which make the color of Hei Cha infusion. Studies found that theaflavins is not only an effective free radical scavenger and anti-oxidants, but also has antibacterial effect for the bud botulinum bacteria, intestinal Bacteroides, Staphylococcus aureus, capsular bacteria, Bacillus cereus. In addition, it has inhibiting effect on theaflavins influenza viruses, rotavirus and enterovirus to a certain extent.
Detoxification, diuretic to reduce tobacco and alcohol poisoning
Caffeine in dark tea increase the discharge of urine by helping water filtering in urine through kidney. At the same time, caffeine can both help discharging urine and sobering up by stimulating bladder. Meanwhile, tea polyphenols in Hei Cha not only can precipitate nicotine and excrete it with the urine, but also can clear free radicals in smoke and reduce the toxic effects of smoke on human health. In addition, tea polyphenols can effectively absorb heavy metals, alleviating the toxic effects of heavy metals.
