Cascara sagrada
Natural History.
Rhamnus Purshiana. (California.) N. O. Rhamnacae. Extract of bark.
Clinical.
Constipation.
Rheumatism.
Characteristics.
I mention this well-known purgative because it has been found empirically curative in cases of subacute and chronic rheumatism with constipation.
Pathogenetic effects on patients taking it for constipation have been recorded: Vomiting, severe griping, hemorrhage, in one case temporary insanity (from a home-made decoction of the bark).
In two cases choleraic symptoms were produced.
Only material doses have been used.
