Syrupus Senegae. U. S. Syrup of Senega. Syr. Seneg.
Sirop de Polygala, Fr.; Sirupus Senegae, P. G.; Senega-sirup, G.
"Fluidextract of Senega, two hundred mils [or 6 fluidounces, 366 minims]; Syrup, a sufficient quantity, to make one thousand mils [or 33 fluidounces, 6 ½ fluidrachms]. Mix the fluid-extract with sufficient syrup to make the product measure one thousand mils [or 33 fluidounces, 6 ½ fluidrachms]." U. S.
The syrup affords a very convenient mode of exhibiting senega in pectoral complaints. Owing to the pectinous principle present in senega, the syrup made directly from the root as in the process of 1870 was always turbid. It has been frequently pointed out that the addition of an alkali renders the syrup transparent, and the 1890 process directed the use of a small quantity of ammonia water, although, if the fluidextract of senega which contains alkali be used as in the U. S. P. IX, this addition is unnecessary. This syrup may be given as a nauseating expectorant.
Dose, one or two fluidrachms (3.75 or 7.5 mils).
