Cure for unsightly warts

Skin warts were considered unsightly as far back as the 13th century. Here's a cure that dates from about 1250:

Procure a live eel - fresh or salt water – and cut off its head. Then anoint those parts of the body afflicted with warts, using the fresh blood of the eel. Allow to stand until the blood dries. Do not wash off for at least three days. Bury the head of the eel deep in the earth. Remember where you buried it, so you can check its decomposition. As the head of the eel rots over time, the warts will disappear.

(This cure generally works better in the summer months, because the eel's head rots faster)
