In yaku, antioxidants are so high that green tea is good for health. Researchers from London’s Swansea University claim that 80% of the cells that cause leaf lung cancer can be avoided due to the presence of polyphenols, amino acids, and vitamins. For that purpose, they collected the leaf drugs in the form of nanoparticles and demonstrated on cancer cells, almost all of them died. It has also been shown that no other side effects from tea have been caused by other cancer drugs. Compared to other chemicals, this is less expensive. So soon researchers try to create tea as a cancer drug.
