"Throughout Italy, and at Rome, a decoction of fresh Lemons is extolled as a specific against intermittent fever; for which purpose a fresh unpeeled Lemon is cut into thin slices, and put into an earthenware jar with three breakfastcupfuls of cold water, and boiled down to one cupful, which is strained, the lemon being squeezed, and the decoction being given shortly before the access of fever is expected."
