While there are many species of buckthorn, only the Northwest United States native produces the medicinal properties found in commercial preparations as a gentle, non-habit forming way to relieve constipation. The bark is harvested and sold for use in several forms, teas, pills and liquid extract. It also acts as a bitter digestive tonic that improves liver function.
The bark is so potent that, after harvesting, it must be heated to promote oxidation or stored for one year to weaken it. Buckthorn will then work to cause the stool to better absorb water, gently softening it for elimination with less irritation than some of the other natural laxatives, such as aloe and senna.
The anthraquinone glycosides in buckthorn tea have both laxative and diuretic effects. These substances bind water in the intestines, gently soften the stool and at the same time stimulate intestinal motion. Continued use, however, will cause the body to shed not only water but also potassium, which can lead to a serious deficiency. Buckthorn’s laxative effect also disrupts the absorption of electrolytes. Because of this, buckthorn alone should not be taken for more than a few days in a row. When mixed with other herbs it can be used for one week.

A Word Of Caution
Do not exceed the recommended dosages of buckthorn. If you experience intestinal cramping or diarrhea, discontinue using the tea altogether. Pregnant or nursing women should not drink it either.
