Tajārib means experiences or trials. In the casebook, a patient's
complaint could prompt questions about taste, sleep, pain, urine, or other
signs before al-Razi recommended a diet, compound medicine, bloodletting,
or another intervention. A study comparing its eye cases with his formal
medical works found that practice did not simply enact the more elaborate
theory described in textbooks. The casebook is therefore evidence for
variation and practical choice, not proof that every recommendation was
effective (Álvarez Millán;
Álvarez Millán).
These treatments belonged to a humoral understanding of bodies. Health
depended on the balance and movement of bodily qualities and fluids;
food, sleep, activity, evacuation, and drugs could all alter a patient's
condition. Terms translated as “melancholy,” “dropsy,” or “brain fever”
are historical categories, not diagnoses that can be mapped automatically
onto present-day psychiatry, oedema, or infection
(Adamson;
Pormann).
Some records include women, children, poor patients, and consultations at
home as well as in hospitals. One case describes a woman whose confused
speech and laughter were interpreted as humoral “melancholy”; no outcome
was recorded. Such entries widen the social field beyond rulers and male
scholars, yet patients' own explanations survive only through a physician
or pupil, and women practitioners remain especially difficult to recover
(Pormann).
