Bloodletting and Purging aimed to make the Humours balanced
1. Bloodletting and purging were popular treatments because they fitted in with the Four Humours Theory
2. If someone apparently had too much blood inside them, the doctor would take blood out of their body through bloodletting - they might make a small cut to remove the blood or use blood-sucking leeches
3. Some people were accidentally killed because too much blood was taken
4. Purging is the act of getting rid of other fluids from the body by excreting - doctors gave their patients laxatives to help the purging process
