PHARMACEUTICAL NOTICES. 
Take of Pink root, - - - (Av,) IG ounces. 
Senna, - 8 ounces. 
^ Powdered sugar, - - 24 ounces. 
Carbonate of potassa, - - 1 ounce. 
Oil of Caraway, 
Oil of Anise, of each half a dram. 
Diluted alcohol, a sufficient quantity. 
The pink root and senna are reduced to coarse powder, 
mixed with two pints of diluted alcohol, and macerated for 
two days. The mixtare is then placed in a displacer, and 
more diluted alcohol gradually added, until five pints of 
tincture have passed, observing that the liquid passes slowly 
and regularly. This is evaporated in a water bath to twenty 
fluid ounces, and the carbonate of potassa added and mixed, 
which dissolves the resinous and extractive sediment. The 
volatile oils are now triturated with a portion of the sugar, 
and then with the rest, and the whole mixed with the 
evaporated liquid, and by means of a very gentle heat cause 
the solution of the sugar. The whole should measure, 
when completed, two pints. 
The carbonate of potassa, not only gives solubility to the 
matters deposited by the evaporation of the alcohol, and 
corrects the griping tendency of the senna, in part, but its- 
self, in the opinion of some, possesses anthelmintic power. 
The relation of the two chief ingredients is that in which 
they are most usually prescribed. 
The dose varies from half a teaspoonful to a child of one 
or two years, to a tablespoonful for an adult.
