A "hand-written book of medicinal recipes" was passed down to Marc Simmons from an ancestor who doctored folks in Mississippi just prior to the Civil War. His remedy for malarial "fever and ague" makes bleeding by leeches seem like a treat:
Take a lump of cow excrement as large as a hen egg from a cowpie dropped in the month of May. Wrap it in a rag and put it in a pitcher with a little sage, horsemint and other sweating herbs. This will produce a half-gallon of strong tea, but not so strong as to make the patient sick. Drink plenty to cause sweating. [Link]I'd be sweating as soon as I saw the doctor pull a cowpie out of his bag.
