Tormentil is a plant in the rose family that has been traditionally used for stomach problems, bleeding, and wound healing.
Some evidence suggests that tormentil may be of benefit for diarrhea. Tormentil has also been studied for other conditions. However, the available human research is limited. More studies are needed.
