Alcohol abuse also interferes with the body's ability to heal ulcers."We found that extracts of black tea engage in anti-ulcer activity and helps mitigate its negative effects," Anirban Roy, a scientist at the drug development diagnostics and biotechnology division of the Council of Scientific and Industrial Research - Indian Institute of Chemical Biology, said.

He was speaking on the sidelines of the Cesin International Conference at the institute. Roy said aqueous extract of black tea was shown to exert regulatory effects over a group of proteins that play a vital role during the development and healing of gastric ulcer.

"Moreover, the extract restored the integrity of the cells against alcohol insult," said Roy, one of the researchers who conducted the study.

Another highlight of the study was that addition of citric acid to the black tea extract provides stronger protection against ulcers, as compared to the extract alone, he said.
