An Excellent Bitter
Cut 1/2 oz. of gentian in thin slices into a stone jar, with the same quantity of fresh orange peel and sliced ginger. Pour over them 1 quart of boiling water, and let it stand ten hours. Strain it, add a gill of sherry, and bottle it. For a weak stomach, a wine-glassful the first thing in the morning will create an appetite.

Wheat Gruel for Young Children with weak stomachs, or for Invalids
Tie half a pint of wheat flour in thick cotton, and boil it three or four hours; then dry the lump and grate it when you use it. Prepare a gruel of it by making a thin paste, and pouring it into boiling milk and water, and flavor with salt. This is good for teething children.
