Slippery Elm Bark is native to North America. A soothing, mucilaginous herb, slippery elm bark is used internally to soothe digestion and support bowel movements. The consistency comes from a high content of soluble fiber, which makes it valuable as a fiber laxative. As a poultice, it has been traditionally used to soothe dry skin. It is also a favorite of Western herbalism for usefulness in soothing a sore throat.
