Both the leaves and root are used medicinally. It’s very emollient and demulcent, and mildly anti-inflammatory, which makes it an ideal herb for treating gastric ulcers. It’s also expectorant and coupled with its soothing properties it helps to relieve coughs. It also has a strong affinity with the urinary tract, helping to dissolve crystals, lubricating the internal tissues and acting as an immunostimulant. The dried powdered root is an excellent drawing agent for abscesses and puncture wounds when combined in equal proportions with slippery elm inner bark powder.
