The healing
power of maggots is not new. Human
beings have discovered it several
times. The Maya are said to have used maggots for therapeutic purposes a thousand years ago. As early as the
sixteenth century, European doctors noticed that soldiers with maggot-infested wounds healed well. More recently,
doctors have realized that maggots can be
cheaper and more effective than drugs in some respects, and these squirming larvae have, at times, enjoyed a
quiet medical renaissance. The problem may have more to do with the weak stomachs of those using them than with good
science. The modern heyday of maggot therapy began
during World War I, when an American doctor named
William Baer was shocked to notice that two soldiers who had lain on a battlefield for a week while their
abdominal wounds became infested with thousands of maggots, had recovered better than wounded men treated in the
military hospital. After the war, Baer proved to the medical establishment that maggots could cure
some of the toughest infections.
In the 1930s hundreds
of hospitals used maggot therapy. Maggot
therapy requires the right kind of larvae. Only the
maggots of blowflies (a family that includes common bluebottles and
greenbottles) will do the job; they devour dead tissue,
whether in an open wound or in a corpse. Some other
maggots, on the other hand, such as those of the screw-worm eat live
tissue. They must be avoided. When blowfly eggs hatch in a patient’s wound, the maggots eat the dead flesh where gangrene-causing
bacteria thrive. They also excrete
compounds that are lethal to bacteria they don't happen
to swallow. Meanwhile, they ignore live flesh,
and in fact, give it a gentle growth-stimulating massage simply by crawling
over it. When they metamorphose into flies, they leave without a trace – although in the process, they might upset the hospital staff as they squirm
around in a live patient. When sulfa drugs,
the first antibiotics, emerged around the time of World War II, maggot therapy quickly faded into obscurity.
