The main active ingredients in bistort are tannins (oligomeric proanthocyanidins, galloyl, and catechol tannins) which are present in very large quantities in the rootstock (15 to 36 percent).
In addition, the rootstock contains flavonoids, flobafen (a reddish-brown pigment), starch (ca. 30 percent), calcium (1 percent), sugar and proteins.
Laxative anthraquinones, which are often found in many plants of the Polygonaceae family, are present in small quantities in bistort.(Herbal Supplement Resource)
