Epigallocatechin Gallate(EGCG)


EGCG is a natural antioxidant and anti-aging substance which can strongly mop up free radicals, suppress cancer, and resist indicative damage. It provides prevention and cure for diabetes, obesity, hyperlipemia, atherosclerosis, and cerebral thrombosis, and helps maintain oral health. EGCG is the first choice for cardiovascular disease and cancer treatment. Currently, research on AIDS treatment with EGCG has attracted worldwide attention of experts on cancer prevention and control.

Theabrownins is a kind of water-soluble pigment, belonging to polyphenols, mainly composed of theaflavins and thearubigins by oxidation polymerization. Also it is a kind of very complex structure product which is oxidized and polymerized by catechins. Theabrownins is one of the main bioactive components of tea, also the most stable in the tea pigment,the molecular weight also the largest, which pH value is between 8 to 10, belonging to weak alkaline. It’s very beneficial to improve the body’s comprehensive metabolic balance, and there is a very obvious effect to ease blood sugar,blood fat, blood pressure, uric acid; In fact, people have consensus on the function of the pu’er tea, which main ingredient is theabrownins, commonly knowed as : the gold in pu ’er tea!
