Cream of Tartar is a purgative and refrigerant.
It is _used internally_ in dropsy, especially of the belly, in doses
of from one scruple to one drachm. As a refrigerant drink it is
dissolved in hot water, and sweetened with sugar, and is used in
febrile diseases, care being taken not to allow it to rest too much
upon the bowels.
_Dose_, as a _purgative_, from two to four drachms, as a _hydrogogue_,
from four to six drachms, mixed with honey or treacle.
_Caution._--Its use should be followed by tonics, especially gentian
and angostura.
