Bistort Benefits

The rhizome of the bistort plant is very difficult to uproot and forms two angles, as its name shows: bistort means twice crooked. It is reddish and presents a high percentage of starch, thus being used as food in times of famine.

Healing Properties

bistort root
The rhizome (underground stem) of the bistort is rich in astringent tannins, which dry out and cicatrize the mouth and intestinal mucous membrane.

The rhizome of the this plant contains plenty of gallic and catechic tannins, which give the plant a solid astringent action. It is probably one of the most astringent plants known. The bistort acts locally by drying, cicatrizing, and “tanning” the skin and the mucous membranes of the body. It also has antiseptic (fighting infections) and hemostatic (stopping small hemorrhages) actions. Therefore, it is recommended in the following cases:

  • Gingivitis and periodontists (weak and bleeding gums) applied in oral rinses with the cold extract of the rhizome.
  • Stomatitis (inflammation of the mouth mucous membrane), and pharyngitis, applied in mouth rinses with the cold extract of the rhizome.
  • Diarrhea and gastroenteritis, especially when they appear with infection and hemorrhage (dysentery, salmonellosis, cholera).
  • Vaginitis (inflammation of the vagina), which appears with leukorrhea (vaginal flow, whitish and abundant).

  1. Decoction with 20 to 30 grams of ground rhizome per liter of water, drinking three or four cups daily.
