Two hundred fifty years ago, events were unfolding that would change the course of history. The Continental Congress adopted the Declaration of Independence on July 4, 1776, marking the colonies’ separation from England and the eventual birth of the United States.
The early history of the country was marked by a break with existing authority and a wave of innovation that became a defining characteristic of the new nation. The practice of medicine in the colonies reflected this process. Just as the 13 colonies would be transformed by revolution into the United States, traditional medical practice would gradually evolve into scientific medicine.
Medical practice in the colonies began by imitating European models brought by colonists. People could consult a variety of healers. Physicians held the highest status, diagnosing diseases and prescribing medications.
Those medicines were then mixed and compounded by apothecaries. Barbers, also called barber-surgeons, treated wounds, pulled teeth and performed other surface treatments, including shaving and cutting hair.
The iconic barber pole originated in this era. Its red spiral symbolized a blood-soaked bandage wrapped around a pole, advertising the services available inside the shop. Midwives assisted with childbirth and other aspects of women’s health.
In some ways, this arrangement resembles the modern medical system, with a variety of professionals performing distinct roles. However, the reality was very different.
Medicine in the colonial period was still based on the humoral theory of health and disease, which dated back to ancient Greece and remained largely unchanged since medieval times. The theory of four humors is attributed to Hippocrates of Cos, the “father of Western medicine,” and was later expanded by the Greek physician Galen, who practiced in the Roman Empire.
According to the theory, the body contains four fluids that must remain in balance: blood, black bile, yellow bile and phlegm. Physicians attempted to restore balance through diet, massage, sweating, purging, administering enemas and bleeding patients.
These ideas remained dominant for nearly 1,500 years. They were first seriously questioned in the 16th century and were gradually displaced in the 18th and 19th centuries as anatomy, pathology, pharmacology and microbiology began to develop.
There were two medical schools in the colonies: the Teaching College of Philadelphia, now the University of Pennsylvania, and King’s College in New York, now Columbia University.
Affluent colonists could travel to Europe, particularly to Edinburgh, Scotland, for medical training. However, few could afford the cost of travel and years of study abroad.
Formal medical education of the time was not especially innovative. It relied heavily on lectures and textbook reading, often delivered verbatim to students.
Anatomical dissection was limited. A few bodies per year were available in cities such as London and Edinburgh. These were typically executed criminals, whose bodies were used for study as part of their punishment. Because the bodies were not embalmed and dissection techniques were limited, demonstrations were often unclear and still guided by outdated ideas from Galen.
Most practitioners, roughly 90%, did not receive formal schooling. Instead, they trained as apprentices under experienced physicians. While this increased the number of practitioners, it also meant there was no standardization or quality control. Anyone could claim to be a physician and begin practice, even without training.
Even well-intentioned practitioners faced significant challenges due to limited knowledge. About 25% of infants died in their first year, and nearly one in eight women died during childbirth, in part because women had more pregnancies at younger ages.
Diseases such as smallpox, typhus, malaria and dysentery were widespread, and physicians had few effective treatments. Isolating sick patients was one of the most effective measures, but overcrowding and inconsistent compliance made this difficult.
Available remedies were often ineffective. Alcohol and opiates could reduce pain but not eliminate it. Some treatments were harmful, including the use of mercury for syphilis.
Access to reliable medical care was uncertain, especially as the colonies moved toward revolution. At the same time, advances in science were beginning to reshape medicine.
Before those changes fully took hold, colonists would endure the hardships of war.
