Abstract
In medieval medical anthropology, emotions are closely tied up with humoral pathology, e.g. joy with blood, anger with yellow bile, and sorrow with black bile. The face and body are external signs of a person's constitutional emotionality. Health is based on mental stability: Rage should be channelled into something constructive; love-sickness can even cause death. The use of drugs must respect emotional side effects: While some herbs and gems can brighten the mind, others cause sadness und discomfort. Inadequate emotions not only cause mental illnesses, but can also be mental illnesses in themselves, e.g. raving madness or deep depression. Thus, calming and cheering psychotherapy complements dietary, physical, medicinal, and surgical treatment.
