Chills and Fever, Horse-radish for
“Take fresh green horseradish leaves, bruise and mash them to the consistency of a poultice and bind on the bottom of the feet. This will tend to reduce the fever and is a reliable remedy. I have often used this with great satisfaction.”

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.
