Muhammad ibn Zakariya al-Razi’s Bimaristan

Origin
Muhammad ibn Zakariya al-Razi was a Persian alchemist, philosopher, scientist and foremost physician. An early proponent of experimental medicine, he pushed for observing illnesses to understand their root cause and how to treat them effectively. As a teacher respected by his pupils, he devoted himself to his pupils and patients, regardless of class. This probably lead to al-Razi working heavily in bimaristans, Islamic places of hospitality and medical care where no patient was turned away because of their background. Some of his work included using humorism to differentiate between diseases, such as measles and smallpox, and explaining on a professional level the importance of a standard of ethics in medicine.

Effects
Fashioned out of stone and some simple type of mortar, it is the size of a small building with multiple wings to house separate patients. Allows all inhabitants to body swap with each other, gaining temporary control over another’s body. Each transfer between the healthy and ill incrementally cures the sick until the condition is negligible. It can cause unexpected illnesses and injuries to suddenly appear, even when two healthy people switch with each other.
