Cascara Sagrada

Cascara Sagrada

(Frangula purshiana) Cascara sagrada, the bark of a particular type of buckthorn tree, is a strong laxative. It has a long history of use, and was given its name, meaning sacred bark, because of its medicinal virtues.
Today, cascara is marketed in everything from "miracle weight-loss" formulas to general "cleansing" formulas. Although many professional herbalists and herb users find cascara to be very useful in a limited set of circumstances, most will agree that such a level of over-marketing does not represent wise use of natural resources. Although careful, sustainable harvesting of this bark (or virtually any other bark) is not difficult, improper methods of harvesting can kill a tree while taking only a small amount of the bark, leaving the rest to go to waste and destroying a tree which was years in the growing.
