Humoral Theory: The Hippocratic theory that the human body is composed of four humors (blood, phlegm, yellow bile, and black bile), and that an imbalance in these humors can lead to physical and mental illness.
Temperament:The Hippocratic concept of four basic personality types (sanguine, choleric, melancholic, and phlegmatic) based on the predominance of different humors in an individual.
Holistic Approach: Hippocrates' belief that the mind and body are interconnected, and that treating the whole person, rather than just the symptoms, is essential for good health.
