The Four Humours Theory in Medicine
Concept Map
The Four Humours Theory, originating from Hippocrates, posits that health is governed by four bodily fluids, each linked to natural elements and temperaments. Galen of Pergamon later expanded this theory, which influenced medieval medicine through practices like bloodletting and the use of opposites in treatments. Despite its decline with advancements in Renaissance medicine, the theory's cultural impact persists in language and personality assessments.

The Origins and Principles of the Four Humours Theory
The Four Humours Theory is a foundational concept in the history of medicine, attributed to the ancient Greek physician Hippocrates, who lived from approximately 460 to 370 BCE. This theory suggests that human health and temperament are influenced by four primary bodily fluids: blood, phlegm, yellow bile, and black bile. Each humour is thought to correspond with one of the four elements of nature—air, water, fire, and earth—and is associated with specific personality characteristics. The sanguine humour, connected to blood and the element of air, is described as warm and moist. The phlegmatic humour, related to phlegm and water, is cool and moist. The choleric humour, linked to yellow bile and fire, is warm and dry, and the melancholic humour, associated with black bile and earth, is cool and dry. The balance of these humours was believed to be crucial for maintaining health, with any imbalance potentially leading to disease.Galen's Contributions to Humoral Theory and Its Medical Influence
Galen of Pergamon, a prominent Roman physician and philosopher who lived from around 130 to 200 CE, expanded upon the Four Humours Theory established by Hippocrates. Galen's extensive writings and formulations, including the famous therapeutic concoction known as theriac, were instrumental in advancing medical knowledge. His interpretations of humoral theory became deeply entrenched in medical practice and education throughout the Middle Ages, particularly in Europe. The Church, which was a dominant force in medieval society, played a significant role in preserving and promoting Galenic and Hippocratic texts, as they were not in conflict with Christian doctrine. These texts were foundational in the training of physicians and the preparation of medicines by apothecaries, thereby influencing the medical treatments and public health measures of the era.Humoral Theory in Medieval Diagnosis and Treatment
In the Medieval period, the Four Humours Theory was central to the medical profession's approach to understanding and treating illnesses. Physicians, typically educated at universities, would diagnose a patient's condition based on the perceived imbalance of humours and prescribe treatments aimed at restoring equilibrium. Common interventions included bloodletting, to address an excess of blood, and purging, to remove an overabundance of yellow bile. The Principle of Opposites was a guiding concept, where treatments were selected for their ability to counter the qualities of the predominant humour. For instance, to counteract an excess of the cold and moist phlegmatic humour, a physician might prescribe a hot and dry substance like mustard seeds. Apothecaries, who were responsible for the preparation and sale of medicinal remedies, were integral to the healthcare system of the time.Endurance and Evolution of the Four Humours in Renaissance Medicine
The Renaissance era, a time of significant scientific and cultural transformation, saw the continued influence of the Four Humours Theory in medicine. The advent of the printing press in the 15th century, pioneered by Johannes Gutenberg, democratized access to medical knowledge and reduced ecclesiastical control over its dissemination. Pioneering physicians such as Andreas Vesalius, Ambroise Paré, and William Harvey made revolutionary contributions to the fields of anatomy and surgery, which began to challenge the validity of Galenic theories. Despite these scientific advancements, the Four Humours Theory remained a prevalent explanation for disease among the general population well into the 18th century.The Decline and Cultural Impact of the Four Humours Theory
The Four Humours Theory significantly shaped medical practices, dietary regimens, and lifestyle choices in medieval Britain, as well as influencing personality assessments. However, the theory's emphasis on balancing humours did not effectively address the actual causes of devastating diseases such as the plague and leprosy. By the 18th century, the medical community largely abandoned the Four Humours Theory, although it persisted in popular belief. The theory's legacy endures in modern language and culture, with expressions like "a sense of humour" originating from this ancient medical concept. Despite its eventual replacement by more scientifically grounded medical models, the Four Humours Theory remains an important historical framework for understanding the evolution of medical thought and practice.
