For hundreds of years, Native Americans have used slippery elm bark for its beneficial and soothing properties. Slippery elm is a large, deciduous tree native to eastern North America known for its mucilaginous, strengthening, and nutritive properties. Our slippery elm powder is finely ground from the inner bark of Ulmus rubra. It can be applied topically, infused into skin care products, or steeped into a mucilaginous drink.
