DW: Nope. Just chop it off. No. No. No.
Everything old is new again, and that apparently includes maggot-based healthcare. Maggot therapy uses lab-raised, germ-free fly larvae that are FDA-cleared medical devices. The maggots eat only dead tissue, secreting digestive enzymes that dissolve necrotic flesh without touching healthy cells, achieving a level of precision a scalpel simply cannot. The dead tissue literally melts away, and patients feel no pain.
It's not a new idea, of course. Ancient civilizations observed that maggots helped battlefield wounds heal, and modern maggot therapy was pioneered in the 1990s. Today, it's used most often when a patient can't safely undergo surgery, such as people with severe heart failure, diabetes, or other conditions that make anesthesia risky. The biggest obstacles to wider use are insurance reimbursement, the general "yuck factor," and a limited body of clinical data. Maggots are also cheaper than standard enzyme-based wound treatments, which insurance does cover.
