Syrups, official and non-official, are so numerous and present no especial points of differentiation from the oils, tinctures, and fluidextracts or the chemical substances entering into them, so we will not enter into details concerning them. The general tendency is to limit their use, since they are cumbersome and the sugar is seldom relished by sick persons, and usually deranges the stomach. The syrup of the iodide of iron is an exception to the general rule that syrups are unnecessary in that the sugar in this syrup acts as a preventive of chemical destructive changes. Emetics, such as ipecac, squill, and sanguinaria, may at times be given with advantage in syrup, and syrups of the hypophosphites and other agents taken by persons engaged in their daily labor and capable of properly digesting the sugar may fill a useful place in therapeutics.
