Cascara Sagrada BarkRhamnus purshiana |
||||
Cascara sagrada bark consists of the dried bark of Rhamnus purshiana D.C. (syn. Frangula purshiana (D.C.) A. Gray ex J.C. Cooper) L. [Fam. Rhamnaceae].
The bark of cascara sagrada must be aged or heat treated prior to use.
Primary active ingredients in the bark are anthraglycosides (anthraquinones), consisting primarily of cascarosides A, B, C, and D; and barbaloin and chrysaloin.
The remaining anthranoids consist of the aloe-emodin type, in addition to those of the chrysophanol and physcion types.
Unless otherwise prescribed: 20mg. to 30mg. hydroxyanthracene derivatives daily calculated as cascaroside A, or equivalent preparations. The correct dosage is the smallest dosage necessary to maintain a soft stool.
Duration of administration: Patients should not treat themselves with stimulating laxatives over an extended period of time (1 to 2 weeks). Using stimulating laxatives longer than recommended can cause intestinal sluggishness.
