What is Tormentil?

Tormentil is an herb. The root is used to make medicine.

People use tormentil as a tea for diarrhea, stomach problems, and fever.

Tormentil tincture, an alcoholic preparation of the root, is sometimes applied to small cuts to stop bleeding. It is also added to water and used as a rinse or mouthwash to treat sore mouth and throat.

Insufficient Evidence to Rate Effectiveness for...

  • Mouth sores (lichen planus). Early research suggests that gargling with a tormentil solution, applying codfish oil to the affected area, and taking conventional medicine to stimulate the immune system shortens flare-ups of lichen planus compared to taking only conventional medicines to stimulate the immune system.
  • Ulcerative colitis. Early research suggests that taking tormentil extract daily for 3 weeks may reduce symptoms of ulcerative colitis.
  • Fever.
  • Stomach complaints.
  • Diarrhea.
  • Stopping bleeding, when applied to small cuts.
  • Sore mouth and throat, when used as a mouthwash.
  • Other conditions.
More evidence is needed to rate the effectiveness of tormentil for these uses.

How does Tormentil work?
