The slippery elm is native to North America and gets its name from the high mucilage, or slippery, content. The bark has long been considered healthful: Native Americans used slippery elm bark to treat sore throats, coughs, mastitis and many other ailments, as did the Colonists who followed their example. Today, people use slippery elm in tinctures, syrups, throat lozenges, and, of course, teas. The soft, powdery bark of the slippery elm is multi-faceted: You can soak it in cold water then add it to juice, pureed fruit, and hot cereals… among other possibilities. For tea, add a teaspoon of Slippery Elm to a glass jar half filled with cold water, put the lid on tight, and shake. Then add hot water and shake again. Let the tea sit for only a minute or two: the longer it sits, the thicker it becomes. Comes in a clear container. Store in a dark, cool shelf with other herbs, spices or teas.
