Because some areas think that some people get sick because they are possessed by ghosts, they can be cured by doing some exorcism rituals and eating garlic afterwards. It is even said that some people have wounds, and they even put salt on them. Actually, this is a typical European exorcism. The second is some extreme measures, mainly for some big wounds.
Because in foreign countries, if some injured people are too serious to heal themselves, foreign doctors will adopt some extreme methods, such as putting a hot red-hot soldering iron on the wound, which is beyond the ordinary people's endurance. For example, some wounds are relatively large, and most doctors will recommend direct excision. It is not necessary to know that there was no disinfection at that time, so most people died of wound infection.
The third way is bloodletting, which is generally used for minor illnesses such as minor colds, fever and stomachache, because in the theory of Europe at that time, the human body should achieve a certain balance. If people are sick, it is only necessary to release some blood. If the illness is serious, they will take a way called enema. At that time, bloodletting therapy was popular in Europe, and even some people would bleed even if they were not sick. They thought it was good for their health, but it was this unscientific method that caused many people to die because of bloodletting therapy.
