Humorism, or humoralism, was a system of medicine detailing the makeup and workings of the human body, adopted by Ancient Greek and Roman physicians and philosophers, positing that an excess or deficiency of any of four distinct bodily fluids in a person—known as humors or humours—directly influences their temperament and health. It is also present in the Indian Ayurveda system of medicine.
The four humors of Hippocratic medicine are black bile (Greek: μέλαινα χολή, melaina chole), yellow bile (Greek: κίτρινη χολή, kitrini chole), phlegm (Greek: φλέγμα, phlegma), and blood (Greek: αἷμα, haima)...
