Answer:
Headaches and stomach pain.
Explanation:
During the medieval times, patients would often get headaches and not know the cure for it. They would go to a medical doctor named Peter Halvorson to inform them about their headache and the doctor would treat them with something bizarre and painful. The doctors will fill in a hole in your skull to 'cure' your headaches.
If you ever have a stomach problem, St Paul, the 'doctor' would make you drink this potion with these ingredients in them: sage, willow, roses, fennel, cinnamon, ginger, cloves, cormorant blood (which was poisonous), mandrake, dragon's blood (not an actual dragon), liquorice and three kinds of pepper.
