When I was a kid and said "I can't be blowed doing something" (an Anglo Saxon explitive meaning I couldn't be bothered) I would get a severe talking to or worse from my father. The being blowed was a vague reference to fly blown, which used to be a common problem in sheep farming, where flies would lay their eggs in live sheep.
Anyway, over the years, maggots have been considered one of the most gross and disgusting forms of life, generally found in rotten meat or dead animals such as roadkill.
We have heard about leech therapy, which has been used for centuries, but now it seems that maggots have been used in the healing process for centuries too and these little creatures have become the next new old thing.
Apparently in the dim dark past they discovered that wounded soldiers who had maggots eating at the rotten flesh on their wounds were more likely to surive than those who didn't.
Now if you asked me to lie in hospital with maggots crawling on my body, I would be horrified and would probably complain to whoever would listen. But it seems that these little larvae secrete an enzyme with very strong healing properties. It's the enzyme that matters. So drug companies like BioPro are now looking at harvesting the enzymes and creating biofunctional textiles which have these enzymes in them, to place on top of wounds, which will have the same effect.
In the past people with wounds that won't heal, sometimes associated with cancer or diabetes have used places like Hyperbaric Chambers which are very high in oxygen to help the body heal itself, but whilst this has had great success, it doesn't always work.
So now they have discovered that the Maggot Enzyme can fight these nasty bugs, so the race is on to understand the enzymes and then synthesize them so that we don't have to build fly farms.
