From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
For a Weak and Dull Head.
When a person has a weak head and is often absent-minded, take hold of an ant's hill, put them into a bag, boil the same for six hours in a kettle of water. Draw this water upon bottles and distil it in the sun. With such water wash the weak and dull head. If the disease is very bad, bathe the patient in such water. The blood of asses should also be drank.
