Botanical InfoSlippery elm is a large tree of the eastern hardwood forests that grows to sixty feet high. The inner bark is harvested to make medicinal tea and other preparations.
DescriptionSlippery elm is a mucilaginous herb used internally to soothe duodenal ulcers, gastritis, chronic diarrhea, sore throats, and coughs. Slippery elm lozenges are excellent to ease a sore throat or relieve any irritation or inflammation of the digestive tract. It is applied locally for wounds, abscesses, and burns. Slippery elm is made into a gruel for convalescence. Some modern herbalists suggest replacing slippery elm with marshmallow root, as slippery elm is becoming scarce.
To make a cold infusion, soak 1 ounce of the shredded bark in 1 pint of cool water until a mucilaginous gel is formed. Use this preparation by the cupful as a soothing drink.

Slippery Elm has a taste of SWEET and a temperature of NEUTRAL.
