For Dropsy

Put a quarter of a pound of cream of tartar, and a pound of new nails, in a stone jug, with half a gallon of water, let it stand three or four days, occasionally shaking it; take a table spoonful three times a day, on an empty stomach, and half an hour after each dose, take two spoonsful of mustard seed or scraped horse-radish. If the swelling abates, you may take the medicine less frequently, or omit every other day, but do not leave it off until you are entirely cured. After it has stood some time, it becomes stronger, when you may put in more water. This has been highly recommended for the dropsy.
