More like it just faded away (out of silliness),
but you still hear references to it in literature ... and some old surgeons.
It has no scientific basis.
There were supposedly four humors (black bile, yellow bile, blood and phlegm). When someone was sick, the four humors must have been out of balance and to heal, the four humors had to be balanced again.
Galen built upon Hippocrates' theory of the four humors by incorporating his own observations and anatomical studies, emphasizing the role of the body's organs and their functions in relation to health. He introduced the concept of the "pneuma," or vital spirit, which connected the humors to the body's physiological processes. Additionally, Galen categorized the humors not only by their qualities (hot, cold, wet, dry) but also by their corresponding organs, thereby creating a more comprehensive understanding of how imbalances could affect health and disease. This integration of anatomy and physiology marked a significant advancement in medical theory.
No, Hippocrates did!
Hippocrates believed that the human body was controlled by four humors, phlegm, black bile, yellow bile and blood. Illnesses were caused by an imbalance of the humors.
The ancient Greek physician Hippocrates first popularize the theory that humors in the body contributed to the temperament of people. Melancholia was it was believed to be caused by an excess of black bile.
Black bile, yellow bile, phlegm and blood.
The theory of the four humors, which originated in ancient Greek medicine, began to decline in popularity during the Renaissance, particularly in the 16th and 17th centuries. By the 19th century, advancements in medical science, such as the development of germ theory and improved understanding of human anatomy, led to the abandonment of humoral theory. While remnants of the idea lingered in some traditional practices, it is largely considered obsolete in modern medicine.
Hippocrates discovered medicine in 400s BC.
Basic to the theory is the concept of the "four humors." These are Dum (blood), Bulghum (phlegm), Sufra (yellow bile), and Sauda (black bile).
Most people believed that diseases were caused by miasma (bad air), the alignment of the stars, the four humors & a punishment from god.
