Leach

The name Leach is rooted in the ancient Anglo-Saxon culture. It is a name for someone who worked as a doctor. Throughout the Middle Ages, doctors were known as "leaches" as the practice of bleeding sick people was the generally accepted manner of curing them. Bleeding was accomplished by placing a dozen or so leaches on the person who was ill so that they could remove the poisons that were making them ill, hence the name "leach" for the occupation of doctor.
