What were the Four Humors that European Doctors in the Middle Ages Wanted to Balance?

Understanding the Concept of Humorism

In the Middle Ages, European doctors believed in the concept of humorism, which was a medical theory that proposed that the human body contained four fluid-like substances, or "humors," that needed to be kept in balance to maintain health and prevent disease. This theory was based on the idea that the four humors were responsible for various bodily functions and that an imbalance of these humors could lead to illness.

The Four Humors: Blood, Phlegm, Yellow Bile, and Black Bile

The four humors that European doctors in the Middle Ages wanted to balance were:

Blood: associated with the season of spring, the element of air, and the qualities of warmth and moisture. People with a dominant blood humor were thought to be optimistic, enthusiastic, and sociable.
Phlegm: associated with the season of winter, the element of water, and the qualities of coldness and moisture. People with a dominant phlegm humor were thought to be calm, reserved, and unemotional.
Yellow Bile: associated with the season of summer, the element of fire, and the qualities of warmth and dryness. People with a dominant yellow bile humor were thought to be energetic, confident, and passionate.
Black Bile: associated with the season of autumn, the element of earth, and the qualities of coldness and dryness. People with a dominant black bile humor were thought to be analytical, critical, and perfectionistic.

The Theory of Humorism

The theory of humorism was based on the idea that the four humors were constantly interacting and influencing each other. When the humors were in balance, the body was healthy and functioning properly. However, when the humors became imbalanced, the body became diseased and symptoms appeared.

Causes of Humor Imbalance

European doctors in the Middle Ages believed that humor imbalance could be caused by a variety of factors, including:

Diet: eating foods that were too hot or too cold, or that were too moist or too dry, could disrupt the balance of the humors.
Climate: living in a climate that was too hot or too cold, or that was too dry or too humid, could also disrupt the balance of the humors.
Emotions: experiencing strong emotions, such as anger or sadness, could also disrupt the balance of the humors.
Injury: suffering an injury, such as a cut or a burn, could also disrupt the balance of the humors.

Treatment of Humor Imbalance

To treat humor imbalance, European doctors in the Middle Ages used a variety of methods, including:

Dietary changes: recommending changes to a person's diet to help restore balance to the humors.
Medications: prescribing medications, such as herbal remedies or purgatives, to help restore balance to the humors.
Bloodletting: performing bloodletting procedures, such as cutting a vein or using a leech, to help restore balance to the humors.
Rest and relaxation: recommending rest and relaxation to help the body recover from illness.

The Legacy of Humorism

Although the theory of humorism is no longer widely accepted in modern medicine, it had a significant impact on the development of medical thought and practice. The concept of humorism influenced the development of various medical theories and practices, including the use of bloodletting and purgatives.

Conclusion

In conclusion, the four humors that European doctors in the Middle Ages wanted to balance were blood, phlegm, yellow bile, and black bile. The theory of humorism was based on the idea that the four humors were responsible for various bodily functions and that an imbalance of these humors could lead to illness.
