“In the Middle Ages, medicine was still in its infancy. The art of healing was conducted not by physicians but by barbers. The medieval barbers were the forerunners of today’s men of medicine, and many of the techniques they developed are still practiced today. This is the story of one such barber.”

“Theodoric of York, Medieval Barber”
In one of the most brilliant skits in Saturday Night Live (SNL) history, guest host Steve Martin plays Theodoric of York, a 14th-century barber-surgeon who confidently attributes his patients’ ailments to bizarre causes, like “toads or a small dwarf living in her stomach.” Guided by supreme overconfidence, he treats every malady with bloodletting, leeches, and stomach-churning poultices made of boar’s vomit or boiled sheep’s urine. As he inflicts these painful treatments, he dismisses his patients’ suffering, entirely unbothered by their predictably bad outcomes.
While this classic sketch is set in the Middle Ages, it perfectly encapsulates the foundations of “heroic medicine”—the dominant allopathic model of the late 18th and 19th centuries. The parallels are striking. When Theodoric’s assistant asks if they should perform the “usual bloodletting,” he confidently applies agonizing treatments to “draw out” illnesses, flawlessly mirroring the brutal logic of early American healthcare.
During this formative period, the medical establishment operated under humoral theory, which viewed the human body as a system of fluid balances. Under this “settled science,” an “over-stimulated” or “congested” system required aggressively forcing toxins out. Early physicians believed that curing an illness required producing a physical effect directly opposite to the symptom—essentially bludgeoning the disease out of the patient.
Samuel Hahnemann, the founder of homeopathy, coined the term “allopathy” (from the Greek allos, meaning “other,” and pathos, meaning “suffering”) to describe this method. Hahnemann argued that attacking symptoms with violent opposites was fundamentally irrational and barbaric, maintaining that these harsh treatments merely weakened the body, inflicted unnecessary suffering, and routinely killed the patient. Yet, top medical schools explicitly taught that these depletion therapies were the most advanced way to save a life; any doctor who refused to bleed a patient or purge their bowels was deemed negligent by his peers.
This philosophy fueled the widespread use of calomel (mercurous chloride), a dangerous mercury compound regularly prescribed as a cure-all from the 16th century until the mid-20th century. Administered as a white powder, this heavy laxative and disinfectant was used to treat everything from constipation and mumps to yellow fever and infant teething. It was often paired with “Blue Mass”—pills crafted by mixing elemental liquid mercury with chalk, licorice, and honey. Calomel wasn’t just some experimental elixir peddled by back-alley hucksters; it was the definitive “go-to” drug for orthodox physicians, heralded as a panacea by the self-proclaimed “ministers of modern medicine.”
