Tea polyphenols are the most abundant soluble component in tea and are also the most important substance for tea to exert its health care effects. The most typical representative is catechin (phenol), which has many functions such as antioxidant (eliminating oxygen free radicals), anti-inflammatory, reducing the incidence of cardiovascular disease, lowering blood lipids, reducing body fat formation, antibacterial, and changing the ecology of intestinal flora. Studies have shown that half an hour after drinking a cup of tea, the antioxidant capacity (ability to resist oxygen free radicals) in the blood increases by 41% to 48%, and can remain at a high level for one and a half hours.

Tea pigments mainly include chlorophyll, β-carotene, etc., which have anti-aging and beauty effects.

Theanine can improve brain function, enhance memory and learning ability. It has a preventive effect on Alzheimer's disease (Alzheimer's disease), Parkinson's disease and autonomic nervous system disorders.

Tea polysaccharide is a complex mixture of ingredients. Tea polysaccharide has the effects of anti-radiation, increasing the number of white blood cells, improving immunity, and can also lower blood sugar. The practice of drinking crude tea to treat diabetes is spread among the people, mainly due to the role of tea polysaccharides. Υ-Aminobutyric acid The content of Υ-aminobutyric acid in natural tea is not high, but its content increases significantly after the tea is processed. The main function of γ-aminobutyric acid is to dilate blood vessels and lower blood pressure, so it can assist in the treatment of hypertension. It can also improve blood circulation in the brain and enhance the metabolic capacity of brain cells, which is helpful in the rehabilitation treatment of stroke (stroke), sequelae of cerebral arteriosclerosis, etc.
