Bloodletting

Bloodletting (or blood-letting) is the withdrawal of blood from a patient to cure or prevent illness and disease. Bloodletting was based on an ancient system of medicine in which blood and other bodily fluids were regarded as "humours" that had to remain in proper balance to maintain health. It is claimed to have been the most common medical practice performed by surgeons from antiquity until the late 19th century, a span of almost 2,000 years. In Europe the practice continued to be relatively common until the end of the 18th century. The practice has now been abandoned by modern style medicine for all except a few very specific conditions. It is conceivable that historically, in the absence of other treatments for hypertension, bloodletting sometimes had a beneficial effect in temporarily reducing blood pressure by reducing blood volume. However, since hypertension is very often asymptomatic and thus undiagnosable without modern methods, this effect was unintentional. In the overwhelming majority of cases, the historical use of bloodletting was harmful to patients.

An example of a blood-letting device. Blades come through those slots. Yikes. The ancient Greeks did this. Heck, it was even a practice used in the formative years of the United States. George Washington is sad to have had this procedure done when he had a throat infection. The arteries were believed to be linked to illness, so letting blood out was supposed to cure the afflicted.

Bloodletting is still perform world-wide by those who cling to this ancient practice, as a means of cleansing.
