Who knew? I just learned a new trick for sore throats. –Allison
Although there’s no hard evidence that it works, sap from the marshmallow plant has been used for hundreds of years—usually in tea form—to treat coughs, colds, and sore throats. And while real marshmallow bears little relation to the puffy campfire treats that took its name, both may have sore throat-fighting properties.
According to anecdotal reports, modern-day marshmallows can help ease sore throat pain, possibly because the gelatin coats and soothes. “It’s not the wackiest thing in the world,” Dr. Linder says. “If your throat is really swollen and it really hurts to swallow anything, I can see how something slippery and sweet like marshmallows might provide some relief.”
