This document discusses two case studies treated by Dr. Subrata K. Banerjea. The first case is of a woman in her late thirties who developed OCD about infectious diseases due to the stress of caring for her autistic child. Dr. Banerjea prescribed Nitric acid which fully resolved her condition in twelve months. The second case is of a seven-year-old boy who was brought to Dr. Banerjea with convulsions. The boy's mother recounted being frightened during her pregnancy, and Dr. Banerjea determined this affected the fetal circulation, causing the convulsions. Opium was prescribed which led to remarkable improvement of the convulsions.
