Slippery-Elm Tea
Pour one cup of boiling water upon one teaspoonful of slippery-elm powder or a piece of the bark. When cool, strain, and flavor with lemon-juice and sugar. This is soothing in any inflammation of the mucous membrane.

Slippery-Elm Bark Tea
Break the bark into bits, pour boiling water over it, cover and let it infuse until cold. Sweeten, ice, and take for summer disorders, or add lemon-juice and drink for a bad cold.
