What were some cures for dieases?

      In the Middle Ages, it was believed the body was made up of four liquids called Humors. It was believed that sickness and disease occurred because the Humors were out of balance, the Humors could be put back in balance by eating good diet or taking prescribed medicines. Another method was blood-letting, cutting open a vein to let the excess blood out, depending on how much blood would be let out certain different methods would be used, but there was always a bowl underneath the cut so the blood was collected. For minor blood-letting, leeches were applied to areas to suck the blood. For major blood-letting, the Surgeons would cut a vein. Sometimes, up to four pints (1.91) of blood would be let out at once! If the paitient fainted at the huge loss of blood, that was seen as a step of the road to recovery.
