Being a student of Appalachian folklore, I have heard some real doozies when it comes to home remedies. My favorite by far is this cure for worms, particularly tapeworm:
Don't eat anything for at least 24 hours. Go as long as you can without eating. Then warm a cupful of fresh cream and sniff deeply. Repeat two or three times, each time drawing the cup a few inches farther from your nose. When the worm comes out your nose to get the cream, reach up, grab it, and pull it out.
Some folks swear by it...
