Strip your slippery-elm in small pieces; take two table spoonsful of these pieces and pour over them two tea cups of boiling water. Let it stand until it becomes mucilaginous, then strain it.
Pour two tea cups of boiling water over two table spoonsful of unground flax-seed. Cover the vessel, and stand it in a warm place until a mucilage is formed. Be careful to keep it closely covered, as it soon becomes stringy if exposed to the air. When sweetened and flavored with lemon-juice it is a very palatable drink.
The lemon-juice should be scalded.

Cut the beef in thin slices, and pour on the water. Cover it and set it in a warm place for three-quarters of an hour, then put it over a slow fire where it will simmer for half an hour. Strain it, and serve it hot or cold as recommended by the physician.
Salt it to the taste.
