White tea is a lightly fermented tea. It uses buds and leaves with more pekoe. Fresh leaves require three whites and inner buds. Both inner leaves should have pekoe exposed. White tea contains not only carbohydrates, but also general nutrients such as protein, fat, vitamins, and mineral elements, as well as functional ingredients such as tea polyphenols, catechins, tea polysaccharides, and theanine. The specific functions and effects are as follows:

1. Resist tumors: Some epidemiological survey data show that white tea has certain anti-cancer effects. It can resist oxidation, scavenge free radicals, and inhibit carcinogens. The formation of it enhances the body's immune function, indirectly kills tumor cells and inhibits the positive binding of carcinogens to human DNA.

2. Protect the cardiovascular system: The caffeine and catechins in white tea can relax blood vessels, increase the effective diameter of blood vessels, dilate blood vessels, and also lower blood pressure. Experiments have shown that injecting tea polysaccharides can lower blood pressure, slow down heart rate, and increase isolated coronary artery flow, thereby protecting the cardiovascular system.

3. Anti-inflammatory and antibacterial: Antibacterial components such as tea polyphenols in white tea have an astringent effect on coagulating proteins and can combine with bacterial proteins to cause bacterial death. In addition to the bactericidal and bacteriostatic effects, the active ingredients in tea can also eliminate toxins formed by Vibrio cholerae, Vibrio parahaemolyticus and Staphylococcus aureus in the human body to avoid toxic effects on the human body.

4. Regulate blood sugar: White tea contains tea polysaccharides, catechin compounds, diphenylamine and other hypoglycemic ingredients. Lipid catechins and theaflavins have obvious inhibitory effects on α-amylase and sucrose. Even at a low concentration of 0.5mmol, they can still have a good effect on lowering blood sugar and at the same time reduce the concentration of insulin in the blood. Levels also dropped.

5. Enhance immunity: The body's immune mechanism is closely related to the microbial composition of the digestive tract. Drinking white tea can increase the proliferation of bifidobacteria in the digestive tract and promote growth. At the same time, it can kill and inhibit the growth of harmful bacteria. Therefore, drinking white tea has certain effects on improving the bacterial structure of the human digestive tract and improving immunity against intestinal diseases.

6. Diuresis and detoxification: The diuretic effect of white tea actually comes from the effect of caffeine on the urinary tubes near the kidneys and stomach, inhibiting the reabsorption of sodium ions, chloride ions and water, so drinking white tea is beneficial to Detoxify and relieve edema.
