It is found that green tea both reduces negative effects of chemotheraphy medicines, which are used for cancer treatment, and increases the positive effects of it on treatment.
A study on effects of green tea on chemotherapy is held by Professor Dr. Omer Kucuk from Emory University Medicine Faculty and Professor Dr. Ayhan Dogukan from Firat University Medicine Faculty and Professor Dr.Kazim Sahin from Veterinary Medicine Faculty of the same university. They experimented green tea on rats which were given chemotherapy medicine and whose kidneys were sickened.
Doctors stated that they achieved reducing the side effects of chemotherapy such as oxidative stress on rats with the help of green tea.
Prof. Dr. Sahin said “Chemotherapy medicines have effects both on cancer cells, which uncontrollably reproduce and on live body cells, which reproduce excessively for body functions. This causes harms on our natural live cells and side effects come out as a result. We have discovered in our study that we can decrease these side effects with green tea. Various side effects are seen on rats which were not given green tea whereas we saw that the side effects were reduced on the rats which we gave a substance called ‘epigallocatechin-3-gallate’, which is found in green tea. Moreover, we found out that this substance also increased the positive effects of chemoterapy medicines.”
He added “ It is already known that green tea has anti-cancer effects, we discovered how it is effective. It is possible now to reduce the side effects of chemotherapy medicines with the help of the substance, ‘epigallocatechin-3-gallate’ in green tea.
