Modern science has found a sensible explanation for the long-time worldwide popularity of this herb: Agrimony contains high concentrations of tannins. These astringent compounds gently tighten and constrict the tissues with which they come into contact.
Because of the tannins, the medicinal uses of agrimony are extensive. When sipped as a tea, for example, agrimony will help control the loose stools of diarrhea. Once cooled, the tea works as a throat gargle to reduce inflammation and relieve sore throat pain. Interestingly, Germany's prestigious Commission E approves of using the herb for these purposes.
Applied topically in the form of a compress or poultice, agrimony can minimize certain types of skin inflammation, such as inflamed hemorrhoids, oozing wounds and rashes, and varicose veins.
Other health-promoting components in agrimony include flavonoids and vitamin C (both antioxidants) as well as certain volatile oils. These substances are credited in test-tube studies with producing mild antiseptic activity against certain disease-causing bacteria and fungi. In lab animals, extracts of the herb have even shown anti-diabetic actions; unfortunately, there has been little research to explore its effectiveness in humans with diabetes.
To prepare a cup of soothing agrimony tea, infuse one to two teaspoons of the dried leaves, stems, or flowers in a cup (8 ounces) of hot water and let it steep for 5 to 15 minutes. To help control diarrhea, drink one cup of agrimony tea up to six times a day.
For topical use, prepare a very strong decoction (boiled tea) and allow the mixture to cool before soaking a compress in it and applying it to the affected area several times a day.
