London: Your daily cup of tea has chemicals that can destroy a deadly hospital superbug which causes severe diarrhoea and other intrestinal diseases, killing 3,000 people a year, a new research has claimed.

A team of researchers at Cardiff University has found that C-diff-clostridium difficile, a bacteria that causes severe diarrhoea and gut based diseases is vulnerable to chemicals found in tea,  The Sun reported.

The team exposed 79 strains of the bacteria to 33 types of tea to see which proved best. It found that checmicals called poluphenols which give tea its flavour, help fight off the bacteria.
