Maggot therapy is a controlled, therapeutic myiasis, says Ronald A. Sherman, M.D. Myiasis is the name of the condition where maggots are infesting a live vertebrate host. By controlling the myiasis to optimize safety and efficacy, one can ensure a very clean wound from which all of the dead infected tissue has been removed, while the healthy tissue remains intact.
