The National Center for Biotechnology Information conducted an experiment in order to check the theory that the black tea has healing powers and if it’s able to prevent lung damage done by smoking.
The tested subjects were guinea pigs who were exposed to several cigarette smoke puffs a day for a period of seven days. During the tests the guinea pigs were given water and black tea. Because of the cigarette smoke the guinea pigs developed oxidative stress, lung damage, inflammation and apoptosis.
The subjects, who were given black tea instead of water, helped proving that these problems were preventable thanks to the antioxidants in the tea. In other words, black tea indeed managed to prevent lung damage in guinea pigs. However, it’s not yet clear if the tea will have the same power over the human body since our organism is more complex than the guinea pigs’.
