This is supposed to be responsible for many of the health benefits of green tea and makes up about one-third of the dry weight of the tea. It is an antioxidant, which acts not only anti-inflammatory, but plays an important role obviously also in the process of tumor growth.
Is believed that EGCG might have a suppressive effect on cancer cells, but in practice, failed attempts by the researchers usually because the drug could not reach the tumor in sufficient concentration. The mouse model, the researchers investigate now, with the help of certain carriers to transport the EGCC in sufficiently large quantities to the tumor. In this way, the amount of cancer cells reduced at 40 percent on the animals significantly, and in another ten percent would stabilize after all, and not continued to grow. On average, the survival time of treated animals prolonged 20-day.
