We found these actual medieval folk cures in an old book about English medical practices in the Middle Ages. So try them at your own risk.
To treat baldness
Rub some horse urine onto your scalp. If horse urine isn’t available, dog urine can be substituted.
Fractures, abscesses, paralysis, epilepsy, nausea, sore throats, and ulcers
Can be cured by eating ancient Egyptian mummies. Though not a common practice these days, in medieval England it was quite the fad. Wealthy Europeans acquired the mummies via a trade route from Egypt. However, the fad ended when those wealthy Europeans discovered they weren’t actually eating ancient mummies, but recently murdered slaves.

Wear the skin of a donkey.
For deafness
Warm up a mixture of a rabbit’s gallstone and fox grease and then pour it into your ear. (Don’t make it too hot, though!)
To treat a child’s case of whooping cough
Feed some milk to a ferret. Whatever milk the ferret doesn’t drink, give to the sick kid.

Boil a red-haired dog in oil, add some worms and some bone marrow from a pig, and then apply the mixture to the affected area.

Coat some baby frogs and/or live spiders in butter and swallow them.

Take a bath in the blood of a dog.
