Scientists hope that a powerful new anti-cancer drugs based on green tea could soon be developed after they found that an extract from the beverage could make almost half of tumours vanish.
Green tea has long been suspected of having anti-cancer properties and the extract has been investigated before. However, this is the first time researchers have managed to make it effective at shrinking tumours.
Previous attempts to capitalise on its cancer-fighting properties have failed because scientists used intravenous drips, which failed to deliver enough of the extract to the tumours themselves.
So, the Strathclyde team devised a “targeted delivery system”, piggy-backing the extract on proteins that carry iron molecules, which cancer tumours Hoover up.
