Slippery Elm
Soothing demulcent herb for digestive and respiratory comfort.
Also known as: Ulmus rubra • Red Elm • Moose Elm
Overview
Slippery elm is a tree native to North America, whose inner bark has been used for centuries in traditional herbal medicine. When mixed with water, the bark creates a mucilage, a slick, gel-like substance that soothes and coats irritated tissues. It is primarily used to relieve symptoms of gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), and other inflammatory digestive conditions. It can also be used topically for wounds and skin inflammation.
Key Benefits
Digestive Soothing
The mucilage coats the esophagus, stomach, and intestines, providing relief from irritation and inflammation associated with GERD, gastritis, and IBD.
Cough and Sore Throat Relief
As a demulcent, it soothes the mucous membranes of the throat, making it a common ingredient in throat lozenges.
Topical Wound Healing
Can be made into a poultice to soothe minor wounds, burns, and skin irritations.
