In the 17th century, European scientists actively believed that eating human remains could cure certain ailments.
At executions, poor people would line up and pay the executioner for some of the spilled blood.
This was based on the "like cures like" bullshit of 17th century medicine.
Egyptian mummies were crumbled into alcohol to create a medicine that would allegedly stop internal bleeding.
A few yummy treats included skull chocolate...
A tasty cocktail called "A King's Drops" which is made of alcohol and crushed skull...
Or a lovely marmalade made of blood if you prefer your blood cooked.
The most shocking part? Europeans condemned Native Americans if they consumed human remains.
