The buckthorn is a shrub native to Europe, Western Asia, and the Middle East. Buckthorn is never used fresh. It is collected in the summer, and then must be aged for at least a year to break down its anthrone chemicals. If the buckthorn is not aged, it is not laxative, it is purgative, causing intense intestinal spasms and vomiting. The herb can be artificially aged by heating or aeration, but some useful constituents may be lost.


1,8-dihydroxy-anthracene derivatives (in the aged bark), flavonoids, and tannins.

Parts Used
