Yes, ancient Greeks believed in the concept of humoral theory, which posited that health and personality were influenced by the balance of four bodily fluids: blood, phlegm, black bile, and yellow bile. Bloodletting was thought to restore balance among these humors, potentially leading to changes in personality and behavior. By removing excess blood, practitioners aimed to alleviate various ailments and improve a person's temperament. However, this belief was part of a broader medical understanding that has since been discredited.
