The history of green tea

According to legend, tea was discovered by a Chinese hero almost 3,000 thousand years BC. He traveled in search of healing herbs with a cauldron in which he boiled water for decoctions, and tea leaves accidentally fell into the cauldron. The drink aroused vigor and gradually the tea spread throughout Asia. Originally used only as a medicine, but over time, tea ceremonies were held for pleasure. New varieties and exotic methods of tea processing were developed – for example, the leaves were fried with rice. In some countries, they not only drink green tea but also eat it: make a salad, pickle it.

The use of green tea in medicine

The benefits of green tea have long been officially recognized in medicine. For example, a study of radiation therapy found that the addition of polyphenols from green tea half an hour before the procedure greatly reduces its effectiveness. It follows from this that green tea increases the body’s resistance to various radiation and binds free radicals, which are one of the causes of aging. The complex effect of substances from green tea on cancer cells has been proven. It slows down their growth and contributes to the destruction of malignant cells. However, drugs based on the extract of green tea have not yet been created; studies have not been conducted for long enough. While the extract is added to other drugs.
