Slippery elm

Ulmus rubra

Medicinal herbsHarvest

The mucilaginous inner bark of an American elm — a slippery tea for a raw throat and a raw gut.

Slippery elm is Ulmus rubra of eastern North America. The inner bark, powdered, makes a bland, slippery gruel and lozenge that traditional North American and Eclectic medicine used for sore throat, cough, and irritated gut. This plate is a purchased powder or a tree you planted; stripping wild elms is how a soothe becomes a conservation problem.

Flavor

Bland, maple-sweet, slippery — more texture than taste. Cinnamon helps the cup.
