OK, try this:
Marshmallows for a sore throat? 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 in modern days have taken 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," we were told by a physician. "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."
