Every time I hear about the use of maggots for healing I think "whoa, cool", then I think about it a bit more and go "ew icky!" Though, I guess if it works that well I'd cope with it if needed.

Maggot Band-Aid
David Pescovitz:
First used centuries ago to treat battlefield wounds, maggots are proving to be a useful treatment to prevent post-operative infections. Maggot debridement therapy (MDT) calls for maggot dressing to be applied to wounds twice a week for up to 72 hours each time. From the press release about a recent study on MDT in the journal Clinical Infectious Diseases:

"Debridement, or the removal of contaminated tissue to expose healthy tissue, can be done surgically. However, maggots that have been disinfected during the egg stage so that they don’t carry bacteria into the wound have their advantages. The larvae preferentially consume dead tissue (steering clear of live), they excrete an antibacterial agent, and they stimulate wound healing--all factors that could be linked to the lower occurrence of infection in maggot-treated wounds."

Now I just need to find the article I remember reading about the medical uses of slugs.
