Humorism

Humorism is an ancient medical theory that suggests health depends on balancing four bodily fluids or "humors": blood, phlegm, yellow bile, and black bile. Each humor is associated with specific traits and elements, and an imbalance was believed to cause illness or personality changes. For example, too much blood was linked to a sanguine, lively temperament, while excess black bile was thought to cause melancholy. This concept influenced medicine for centuries until it was replaced by modern scientific understanding. Humorism emphasizes that health and character result from balancing these fluids within the body.
