PRINCE'S PINE, (_chimaphila_.) This plant is a valuable remedy in dropsy. It possesses diuretic and tonic properties. It does not produce the same prostration that usually attends the administration of diuretics, for its tonic property invigorates the kidneys, while, at the same time, it increases the secretion of urine. The best way of administering it is by decoction. It is made by boiling four ounces of the fresh-bruised leaves in two quarts of water. After straining, a table-spoonful of powdered marshmallows may be added, to be given in pint doses, night and morning. PYROLIGNEOUS ACID. See _Acid_. RASPBERRY LEAVES, (_rubus strigosus_.)
