The primary center for health care was the home, as it was when the ashipu or asu were employed. The majority of health care was provided at the patient’s own house, with the family acting as care givers in whatever capacity their lay knowledge afforded them. Outside of the home, other important sites for religious healing were nearby rivers. The Mesopotamian believed that the rivers had the power to care away evil substances and forces that were causing the illness. Sometimes a small hut was set up for the afflicted person either near the home or the river to aid in the families centralization of home health care.
