Method in the Madness
According to the humoral model of the body, illness resulted from an imbalance of the four humours, or their corruption. Climate, emotional upset, diet, a lack of exercise or the movement of the stars and planets could impact the balance or state of the humours. Different symptoms and illnesses depended upon the balance or condition of the humours. Knowledge of the patient’s individual humoral makeup before illness was essential before a course of treatment could be decided upon.
