The theory of the four humors originated in ancient Greece, primarily attributed to Hippocrates and later expanded by Galen. It posited that human health and temperament were influenced by four bodily fluids: blood, phlegm, yellow bile, and black bile. This theory became a foundational concept in medicine for centuries, influencing both diagnosis and treatment practices in various cultures.
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.
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 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.
It has no scientific basis.
Basic to the theory is the concept of the "four humors." These are Dum (blood), Bulghum (phlegm), Sufra (yellow bile), and Sauda (black bile).
Athena did not codify Hippocrates' ideas about humors; rather, Hippocrates, often referred to as the "Father of Medicine," developed the theory of the four humors: blood, phlegm, yellow bile, and black bile. This theory posited that an imbalance among these humors would affect a person's health and temperament. Athena, as a figure from Greek mythology representing wisdom and warfare, did not have a role in the development or codification of medical theories. Instead, Hippocratic texts and later physicians helped formalize and disseminate these ideas in ancient medicine.
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.
Most people believed that diseases were caused by miasma (bad air), the alignment of the stars, the four humors & a punishment from god.
The theory of humors, which posits that human health and temperament are influenced by four bodily fluids—blood, phlegm, black bile, and yellow bile—can be traced back to ancient Greek physician Hippocrates. However, it was later expanded and popularized by Galen, a Roman physician in the 2nd century AD. This theory dominated medical thinking for centuries until the advent of modern medicine.

Galen, a prominent Greek physician in the Roman Empire, developed the theory of the four humors, which posited that human health and temperament are influenced by the balance of four bodily fluids: blood, phlegm, yellow bile, and black bile. This theory suggested that an imbalance among these humors could lead to physical and mental illness. Galen's work combined observational studies and philosophical ideas, significantly influencing medical practices for centuries until the advent of modern medicine.
