Humorism
en.wikipedia.org/wiki/Humorism
Humorism, the humoral theory, or humoralism, was a system of medicine detailing a supposed makeup and workings of the human body, adopted by Ancient Greek and Roman physicians and philosophers.
Humorism began to fall out of favor in the 17th century and it was definitively disproved in the 1850s with the advent of germ theory, which was able to show that many diseases previously thought to be humoral were in fact caused by microbes.

The concept of "humors" (chemical systems regulating human behaviour) became more prominent from the writing of medical theorist Alcmaeon of Croton (c. 540–500 BC). His list of humors was longer and included fundamental elements described by Empedocles, such as water, earth, fire, air, etc. The concept of "humors" may have origins in Ancient Egyptian medicine,[1] or Mesopotamia,[2] though it was not systemized until ancient Greek thinkers. The word humor is a translation of Greek χυμός,[3] chymos (literally 'juice' or 'sap', metaphorically 'flavor'). Early texts on Indian Ayurveda medicine presented a theory of three humors (doṣas),[4] which they sometimes linked with the five elements (pañca-bhūta): earth, water, fire, air, and space.[5]
Hippocrates is usually credited with applying this idea to medicine. In contrast to Alcmaeon, Hippocrates suggested that humors are the vital bodily fluids: blood, phlegm, yellow bile, and black bile. Alcmaeon and Hippocrates posited that an extreme excess or deficiency of any of the humors (bodily fluid) in a person can be a sign of illness. Hippocrates, and then Galen, suggested that a moderate imbalance in the mixture of these fluids produces behavioral patterns.[6] One of the treatises attributed to Hippocrates, On the Nature of Man, describes the theory as follows:
The Human body contains blood, phlegm, yellow bile, and black bile. These are the things that make up its constitution and cause its pains and health. Health is primarily that state in which these constituent substances are in the correct proportion to each other, both in strength and quantity, and are well mixed. Pain occurs when one of the substances presents either a deficiency or an excess, or is separated in the body and not mixed with others.[7] The body depends heavily on the four humors because their balanced combination helps to keep people in good health. Having the right amount of humor is essential for health. The pathophysiology of disease is consequently brought on by humor excesses and/or deficiencies.[8]
The existence of fundamental biochemical substances and structural components in the body remains a compellingly shared point with Hippocratic beliefs, despite the fact that current science has moved away from those four Hippocratic humors.[8]
Although the theory of the four humors does appear in some Hippocratic texts, other Hippocratic writers accepted the existence of only two humors, while some refrained from discussing the humoral theory at all.[9] Humoralism, or the doctrine of the four temperaments, as a medical theory retained its popularity for centuries, largely through the influence of the writings of Galen (129–201 AD). The four essential elements—humors—that make up the human body, according to Hippocrates, are in harmony with one another and act as a catalyst for preserving health.[8] Hippocrates' theory of four humors was linked with the popular theory of the four elements (earth, fire, water, and air) proposed by Empedocles, but this link was not proposed by Hippocrates or Galen, who referred primarily to bodily fluids. While Galen thought that humors were formed in the body, rather than ingested, he believed that different foods had varying potential to act upon the body to produce different humors. Warm foods, for example, tended to produce yellow bile, while cold foods tended to produce phlegm. Seasons of the year, periods of life, geographic regions, and occupations also influenced the nature of the humors formed. As such, certain seasons and geographic areas were understood to cause imbalances in the humors, leading to varying types of disease across time and place. For example, cities exposed to hot winds were seen as having higher rates of digestive problems as a result of excess phlegm running down from the head, while cities exposed to cold winds were associated with diseases of the lungs, acute diseases, and "hardness of the bowels", as well as ophthalmies (issues of the eyes), and nosebleeds. Cities to the west, meanwhile, were believed to produce weak, unhealthy, pale people that were subject to all manners of disease.[10] In the treatise, On Airs, Waters, and Places, a Hippocratic physician is described arriving to an unnamed city where they test various factors of nature including the wind, water, and soil to predict the direct influence on the diseases specific to the city based on the season and the individual.[11]
A fundamental idea of Hippocratic medicine was the endeavor to pinpoint the origins of illnesses in both the physiology of the human body and the influence of potentially hazardous environmental variables like air, water, and nutrition, and every humor has a distinct composition and is secreted by a different organ.[12] Aristotle's concept of eucrasia—a state resembling equilibrium—and its relationship to the right balance of the four humors allow for the maintenance of human health, offering a more mathematical approach to medicine.[12]
