Abstract:
Bloodletting is an ancient procedure that was utilized for curing the ills of man. This article traces the use of leeches for bloodletting therapy from ancient Greek times to the Chapin Harris era in the 1840s to modern day usage by plastic surgeons. The leech is described as both a parasite and a therapeutic agent. The techniques used by both medicine and dentistry are historically documented.
