Slippery elm bark (Ulmus rubra) has a long history of use in North American traditional herbal medicine, particularly among Indigenous peoples and later among European settlers. Its inner bark is valued for its mucilaginous (gel-like) texture when mixed with water, which is soothing to irritated mucous membranes. Historically, slippery elm has been used as a demulcent and expectorant for various respiratory complaints, including coughs, sore throat, and bronchial irritation. In the context of pneumonia, slippery elm was sometimes used as a supportive remedy to ease throat discomfort and calm coughing, though it was not considered a cure for the underlying infection.

There is scant scientific evidence supporting slippery elm's efficacy for pneumonia specifically. Most modern studies focus on its demulcent properties and potential benefits for gastrointestinal issues rather than respiratory infections. Its use for pneumonia is thus justified primarily by tradition and anecdotal experience rather than by robust clinical trials or pharmacological studies. It may provide symptomatic relief for throat soreness or cough associated with pneumonia, but it should not be considered a substitute for medical treatment, especially for a serious condition like pneumonia. In summary, the use of slippery elm bark for pneumonia is based on traditional practices, with minimal scientific validation.
