The Theory of the Four Humours 1. Origins and Beliefs: o Developed by Hippocrates, often referred to as the "Father of Medicine." o Ancient Greeks believed the body contained four fluids or "humours": blood, yellow bile, black bile, and phlegm. Health required a balance of these humours, while imbalance caused illness. o Each humour was tied to natural elements and seasons: ▪ Blood (Spring, Air) ▪ Yellow Bile (Summer, Fire) ▪ Black Bile (Autumn, Earth) ▪ Phlegm (Winter, Water) 2. Impact and Longevity: o This theory guided medical practice for nearly 2,000 years, heavily influencing treatments during Greek, Roman, and medieval periods. o Despite being incorrect, it was widely accepted, hindering alternative explorations into disease causation until the Renaissance. 3. Treatment Practices: o Greek doctors believed illnesses could be treated by restoring balance: ▪ Bleeding (e.g., with leeches or cups) to remove excess blood. ▪ Vomiting or taking laxatives to expel surplus bile. ▪ Diet and hydration adjustments, like drinking water or keeping cool. ▪ Bathing or inducing sweat to "flush out" sickness. 4. Cultural Context: o The idea made sense to people at the time due to its alignment with observable seasonal changes and elemental philosophy. o It fostered early scientific habits like observation and record-keeping. Broader Historical Context Ancient Greek Medicine:  o Greeks believed the gods could heal, and prayers or sacrifices to deities like Asclepius, the god of healing, were common. o However, Hippocratic medicine emphasized a rational, observation- based approach, creating a tension between science and superstition. Timeline of Knowledge: o Ancient Rome: Continued Greek practices, refining them under figures like Galen. o Dark Ages: Loss of medical knowledge; superstition grew. o Medieval Period: Limited advancement in medicine. o Renaissance: Rediscovery of ancient texts spurred medical innovation and new theories. Key Lessons The Four Humours illustrate how societal beliefs and philosophies shape medical understanding. This theory's dominance highlights the dangers of dogmatic adherence to unproven ideas, stifling scientific progress. The transition from reliance on humoral theory to modern medicine underscores the importance of questioning established norms.
