Black tea has undergone three fermentations during processing. The first fermentation is stacking fermentation, the second fermentation is processing fermentation and the third fermentation is storage fermentation. In the process of storage and fermentation, a large number of microorganisms will be produced. Under the action of probiotics, the ascomycetes in tea will be transformed into active substances, making it taste better and have higher nutritional value. The fermented black tea has good health care effect.
Black tea is rich in active enzymes and various trace elements, which can promote the lipolysis and metabolism of viruses in human body, purify blood, reduce blood viscosity, and enhance human anticoagulant ability. It can accelerate the decomposition of fat in blood, promote blood circulation, and often soak it in water to prevent the increase of blood pressure and blood lipid. Those who already suffer from hypertension and hyperlipidemia insist that soaking in water and drinking black tea can also play an important role in lowering blood pressure and blood lipid, which can maintain human cardiovascular health.
Drinking black tea can not only lower blood pressure and blood fat, but also protect human cardiovascular and cerebrovascular diseases and prevent blood sugar from rising. Because black tea contains active enzymes, vitamins and other effective nutrients, it can regulate the absorption function of human endocrine viruses, enhance the human body's sugar tolerance, accelerate the decomposition and metabolism of sugar substances in the body, prevent blood sugar from rising, and help to lower blood sugar. It is a health tea suitable for patients with hyperglycemia and diabetes.
Black tea is also rich in nutrients beneficial to human body, such as alkaloids, which can accelerate the decomposition and metabolism of lactic acid in human body, maintain the acid-base balance in human environment, improve the anti-fatigue ability of human body and prevent sub-health. Drinking black tea often in water can slow down the aging of the human body, accelerate the metabolism of the body, promote the decomposition of heavy metals in the body, prevent the accumulation of various toxins in the human body and reduce its harm to the human body.
