One of those who caught the plague was Emperor Justinian, but he recovered. (source)

In an attempt to prove his conviction that coffee ws toxic, Sweden's King Gustavus III (1746–1792) performed an unusual experiment. The experiment's subjects were two condemned prisoners, one of whom was given only coffee to drink, the other only tea. Two physicians monitored the two men. Gustavus believed that the coffee drinker would shortly die of acute poisoning, but the first person to die was one of the doctors, followed shortly by the other doctor. Then Gustavus was assassinated. Both of the prisoners survived for several years longer, with the tea drinker dying first. (source)

A Canadian neurologist ran an electroencephalogram (EEG) test on lime Jell-O in 1976 and found the dessert to have brain waves, which are often accepted as an indicator of life. He ran the experiment in the intensive care unit of McMaster University Hospital, in Hamilton, Ontario, and explained the EEG reading as being caused by stray electrical impulses from nearby surgical equipment, paging systems, and the like.

Patients of a doctor in Stromness in the Orkney Islands with high blood pressure and high cholesterol levels are surprised when the prescription they receive is for tubs of herring, which the doctor keeps in his fridge in his surgery.

Nowadays politically neutral doctors such as those of the Red Cross are well-known. The first politically neutral doctors appeared during the third Crusade.

He also organised doctors to visit the camps of prisoners and allowed foreign doctors, such as Richard the Lion-Hearted's doctor, Ranulphe Besace, to visit prisoners. (source)
