Ulmus fulva or Sweet Elm has been used traditionally by the Native Americans for digestive disorders and is now commercially available as an herbal mixture. The tree contains mucilage, which become a gel-like substance when combined with water. This substance then can coat the mouth, stomach and intestines, producing a soothing effect on the digestive tract.

U. fulva grows quickly to a maximum height of 40m. Between the months of February and May, U. fulva produces small, short-stalked, perfect flowers from the buds of the twig. The leaves grow to roughly 18cm long and have jagged edges. The pubescence on the buds and twigs of U. fulva make distinguishable from other Elm species.

Origin / Habitat

U. fulva is a species of the deciduous elm tree native to North America ranging from Maine and southern Quebec to eastern North Dakota; from northern Texas to northern Georgia. Though it typically grows best in moist soils, it can be found in drier climates, as well.

The mucilage in the plant is responsible for its use in soothing mucous membranes of the throat, stomach and intestines. Many of the studies published are on a product known as Essiac, which is a combination of U. fulva and several other herbs. Studies on the individual use of U. fulva are limited.

Several small laboratory studies have investigated the anti-inflammatory activity of U. fulva [3],[4] as well as its antioxidant properties. [5]


At this time, there are not any published clinical studies.
