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.
