Leeches, used by medical practitioners for several centuries to suck blood, are still employed in plastic & reconstructive surgery to anaesthetise wound areas, dilate blood vessels to increase blood flow, & prevent blood from clotting.A substance found in leech saliva, hirudin, which are used to produce drug, offers new hope for heart patients, reducing the chance of a repeat heart attack by nearly a third.
