It's the stuff of horror movies -- blood-sucking leeches, flesh-eating maggots, and venomous lizards. It may sound like voodoo medicine, but these "new" treatments have some amazing healing powers.

Leeches: a Good Thing

Leeches have been granted new-found respect. Medicinal leeches (Hirudo medicinalis) are blood-sucking animals that live in fresh water.

For thousands of years, people used these small, slimy creatures to suck blood with the hopes of curing numerous ailments. It was considered an alternative to bloodletting (draining blood) and amputation.

Today, leeches continue to be used worldwide to help heal wounds and restore circulation in blocked blood vessels.

Just this year, the FDA gave clearance to a French company for commercial marketing of these leeches as a medical device in the U.S. The company has bred leeches for 150 years in a certified facility and tracks each lot of leeches it produces.

Bloodletting's Benefits

Before antibiotics were developed, bloodletting -- draining blood from the body -- was the prescription for scores of serious illnesses. George Washington is said to have had 80 ounces of his blood drained in a last-ditch effort to save his life; it didn't work. As recently as 1942, medical textbooks advocated bloodletting as a treatment for acute pneumonia.
