Slippery elm (Ulmus fulva) has been used as an herbal remedy in North America for centuries.

Slippery elm contains mucilage, a substance that becomes a slick gel when mixed with water. It coats and soothes the mouth, throat, stomach, and intestines; it may also contain antioxidants that can help relieve inflammatory bowel conditions.

Plant Description:
Slippery elm is a medium-sized tree native to North America. It can reach well over 50 feet in height and is topped by spreading branches that form an open crown. The red-brown or orange branches grow downward, and the stalkless flowers are arranged in dense clusters. The plant's leaves are long and green, darkening in color during the fall. The bark has deep fissures, a gummy texture, and a slight but distinct odor.
