What does leacher mean?
A leacher was, above all, a physician or surgeon who used leeches to treat patients. The word belongs to the history of bloodletting, a medical practice in which blood was deliberately removed from the body in the belief that doing so could restore health. Although the treatment is now obsolete, leechers remain associated with earlier periods of medical history and with accounts of doctors, surgeons, and their unusual instruments. The term also has the rarer meaning of a person who catches fish with leeches used as bait. In present-day English, “leacher” is chiefly a historical word, but it is useful for understanding older medical texts and for recognizing the direct connection between the practitioner and the leech. Its unusual sound and its link to a once-common but discredited medical treatment make it particularly memorable.
