Traditionally, the herb has been used in combination with Walnut leaves as an external treatment for wounds, cuts, and scrapes.
The herb is sometimes recommended as a remedy for hemorrhoids by adding the dried herb in the bath water, as a sitz bath or as an eyewash for conjunctivitis.
Digestive system and gallbladder – internal use
Animal studies support some of the traditional use in humans and have shown that the herb may have a certain blood pressure lowering, slight diuretic, and laxative effect.
