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.

Parts Used

Dried bark, properly aged for 1 year as recommended.

Typical Preparations

Best taken as a tablet, can be used as a tea but is hard to drink given its bitter taste. May also be prepared as an extract.


Historically, it has also been used as a dye for textiles.
