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 fluid were regarded as "humors" that had to remain in proper balance to maintain health. It was the most common medical practice performed by physicians from antiquity until the late 19th century, a span of almost 2,000 years. In Europe the practice continued until the end of the 18th century. The practice has now been abandoned for all except a few very specific conditions. It is conceivable that historically, in the absence of other treatments for hypertension, bloodletting could sometimes have 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.

The practice of bloodletting, or phlebotomy, dates back to antiquity. The followers of Hippocrates in the fifth century B.C. strongly believed in bleeding patients, and it is likely that this was done in Egyptian times and probably even before that. Early civilizations may have been inspired by seeing bats remove blood from animals, hippos scratching on trees until they bled, and other animals scratching at diseased body parts for relief. Additionally, there were many human examples of bleeding such as spontaneous nosebleeds and menstruation that had to be explained. It is perhaps these signs in nature that led early civilizations to put it all together: bleeding must have some beneficial value!

From these simple observations came increasingly complex theories as to why bloodletting was necessary and how it worked. An early theory was that there were four main bodily humors: blood, phlegm, black bile, and yellow bile. An imbalance in these humors was postulated as the need for bloodletting, purging, vomiting, etc. Virtually every known medical condition at one time or another was treated by these methods. Bloodletting was used to treat everything from fever and madness to anemia and debility. As one can imagine, treating an anemic patient by removing even more blood was not the best of ideas.

Through the Middle Ages and into the 18th and 19th century there were many strides in medical knowledge with regards to disease states, and anatomy. However, there was not much that could be done in terms of treatment. There were no antibiotics and surgery was in its infancy (in large part due to the lack of quality anesthesia). One of the only therapeutic modalities was to get out the old lancet and let some blood. It can safely be said that this almost never benefited the patient. Perhaps the biggest benefit was to the physician and family, who felt that at least they were doing something, and if the patient died anyway, it was meant to be.

Phlebotomy was carried out, both on humans and animals. Most of these items are from the 18th and 19th centuries.
