Cholera Mixture

Laudanum, tincture of Rhubarb, and spirits of camphor, equal parts. Begin with thirty drops, taken clear and unmixed, with a little sugar placed in the mouth afterwards. Repeat the dose (after every evacuation) increasing it if the case becomes urgent to sixty drops, (a teaspoonful), or ninety if necessary. No household should be without this remedy, particularly in the summer.
