when was the 4 humours theory discovered

Ever wondered about the roots of ancient medicine? Long before modern science, people grappled to understand the complexities of the human body and its ailments. One theory that held sway for centuries was the concept of the four humors, a system that explained everything from personality to sickness. But when did this influential idea first emerge?

The journey begins in ancient Greece, where philosophers and physicians sought natural explanations for the world around them. Around the 5th century BC, the concept of the four humors began to take shape, eventually becoming deeply intertwined with the teachings of Hippocrates, often hailed as the father of Western medicine.

While the exact origins of the theory remain shrouded in the mists of time, it’s believed that Hippocrates and his followers formalized the idea, solidifying its place in medical history. But it was the Roman physician Galen in the 2nd century AD who truly championed the four humors, expanding upon the theory and turning it into a comprehensive medical model that dominated Western thought for over 1,500 years.

The four humors – blood, phlegm, yellow bile, and black bile – were believed to be the fundamental fluids that governed the body’s health and temperament. According to this theory, any imbalance in these humors would lead to illness.

Though we now understand the flaws of this theory in light of modern medicine, its influence on Western thought, language, and even literature is undeniable. Understanding the four humors allows us to trace the evolution of medical understanding and appreciate the long journey that has led to our current scientific knowledge.

Let’s dive deeper into the history of the four humors, exploring its origins, its impact on medicine, and the reasons for its eventual decline.

Advantages and Disadvantages of the Four Humors Theory

Advantages	Disadvantages
