Green tea has been used in folk medicine for many centuries. With the development of the pharmaceutical industry, in addition to infusions of green tea, began to use its extracts, and then individual active components (catechins, bioflavonoids, etc.)? What are the possibilities of green tea-based drugs in mesotherapy, and how to use them correctly?
Over the past ten years, interest in researching the active components of green tea and their use in the treatment of many diseases has not faded. The use of green tea catechins and bioflavonoids in oncology, cardiology, endocrinology, gerontology, dermatology, cosmetology, hepatology and other areas of medicine is being studied. The results published so far show the effectiveness of green tea, its healing properties, many of which are still not fully understood. Let us discuss some of the studied mechanisms of action of green tea.
This is perhaps the most important property that is ensured by the presence of active ingredients in the composition of green tea, such as polyphenols epigallocatechin-3-gallate (EGCG) and epigallocatechin (EGC), flavonoid quercetin (Qu), vitamins C and E. For example, in a study conducted by English urologists on prostate cancer cells, it was found that the addition of epigallocatechin-3-gallate 30 minutes before radiation therapy significantly reduces its effectiveness. The increased resistance of tumor cells is explained by the fact that epigallocatechin-3-gallate doubles the level of superoxide dismutase in them, thereby significantly suppressing free radical oxidation induced by radiation therapy . In addition, epigallocatechi-3-gallate, epicatechin-3-gallate, quercetin, vitamins C and E actively bind free radicals, in particular, superoxide radical and singlet oxygen, protecting cell membranes and DNA from damage .
