Syrups are nearly saturated Solutions of Sugar in Water, in which aromatic or medicinal substances are dissolved.

Syrups should be kept in a cool place, in cork-stoppered bottles, in order to preserve them.

The official Syrup, Syrupus, contains 85 grams of sugar in 100 Cc.: with a smaller proportion of Sugar the syrup may-undergo fermentation (spoil).

The official Syrups are made by different methods: by solution, or mixing the medicinal substances with the syrup; by dissolving the Sugar in the medicinal solution; by extraction from the drug; and by chemical reaction and solution.

They may be divided into (1) the aromatic or adjuvant syrups, and (2) the medicinal syrups, comprising (a) those made from extractive drugs, and (b) those made from chemicals, either by simple solution or by chemical reaction and solution.

The Aromatic or Adjuvant Syrups are mostly used to improve the taste of salty, bitter, or otherwise unpleasant mixtures.

The Extractive Syrups are often made by mixing the Fluid-extract of the respective drugs with Syrup.

Tinctures and Fluidextracts of resinous drugs often precipitate when mixed with Syrups and aqueous solutions. In order to furnish clear mixtures it is therefore sometimes necessary to mix the extractive preparation with Water, clarify the mixture by filtration, and dissolve the sugar in the filtered liquid.

The Chemical Syrups are an elegant class of preparations in which the taste of the medicinal agents is greatly modified. They do not keep well unless put up in small bottles completely filled, ready for dispensing. Except the Syrup of Iodide of Iron, which is best preserved in bottles exposed to light, they should be kept in a cool and dark place.
