Geranium maculatum

How It Works

Cranesbill is high in tannins, which may account for its anti-diarrheal activity.7 Little scientific research exists to clarify cranesbill’s constituents and actions.

How to Use It

A tea can be prepared by boiling 1–2 teaspoons (5–10 grams) of the root for ten to fifteen minutes in 2 cups (500 ml) of water.8 People can drink three (750 ml) or more cups per day. Cranesbill tincture (approximately 1/2 teaspoon or 3 ml) three times per day is also commonly used, although generally in combination with other herbs, for diarrhea. Dried, powdered cranesbill root is sometimes used in an herbal combination to treat Crohn’s disease; however, there are no scientific studies to support this combination.
