Homeopathy treats person in disease, not disease in person. Medicines are selected on the basis of personality traits of an organism.
To understand the personality of a patient, we need to study in detail his nature, likes & dislikes in food, symptoms in detail, past history, family history etc.
This all helps to understand organism in depth and selection of homeopathic medicine.
Some people may consider that these questions are irrelevant and try to avoid answering or give wrong answers but those who know how homeopathy works, tell everything in detail honestly.
Though this procedure is lengthy, it yields beautiful results because such prescriptions are deep acting and gives long lasting benefits to patients.
