One-Sided Diseases

Organon Aphorism §174

Their principal symptom may be either an internal complaint (e.g. a headache of many years’ duration, a diarrhoea of long standing, an ancient cardialgia, etc.), or it may be an affection more of an external kind. Diseases of the latter character are generally distinguished by the name of local maladies.
