Hi I joined to answer any of your questions about maggot therapy. How maggots work and ALL they can do and how to obtain more info on them. My doctors tried for two years to heal my ulcers at a cost of $40,000 and maggots did in under $1,000. Maggots are all "green" before "green" was in. All natural and no side effects, and works much better than any of the conventional methods tried. Remember these are medically produced maggots (disinfected) and FDA approved!
