The buckthorn is a shrub native to Europe, Western Asia, and the Middle East. It has been used as a laxative since the seventeenth century, and it was brought to the United States with early settlers for that purpose. Buckthorn is a popular ingredient in European laxative extracts, tablets, and teas, and, oddly enough, added to sun block. 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:

Properly aged bark. (1 year 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.


Buckthorn bark is one of the botanical ingredients that are in Harry Hoxsey's original folk cancer cure. Although modern variations of his formula do not include buckthorn, there have been tests that show that anthraquinone derivatives in Buckthorn may have anti-cancer properties. The 1, 8-dihydroxy-anthracenes in buckthorn act on the nerves in the intestinal tract, numbing the nerves that hold back stool and stimulating the nerves that propel stool downward. If you experience cramping, you've used too much. Historically, it has also been used as a dye for textiles.


You should not use buckthorn or any other laxative if you have appendicitis, Crohn's disease, or ulcerative colitis. Not recommended for children under 12. Not recommended while pregnant. Avoid long term use, and discontinue in the event of diarrhea or watery stools.
