Soup may soon be safer to eat with the development of a "bandage" for tongues, designed to help ease the pain of burns.
The "bandage" is made up of a medicated strip that has been imbedded with the anesthetic benzocaine, already found in throat lozenges. As it dissolves, the strip releases a controlled dose of the pain-killing drug along with a non-toxic "therapeutic polymer" to promote healing.
