Glycerin isn’t the most commonly used remedy in natural healing, but it is an effective tool for topical inflammation and pain. If you apply glycerin directly to the tongue, it can act as an instant blanket for inflammation, and will quickly soothe the pain and discomfort. While there aren’t many other benefits to glycerin, it can be a first line of defense for treating particularly uncomfortable bouts of burning tongue syndrome. Glycerin is a thick, colorless liquid commonly derived from animal fats and vegetable oils. Animal fats are particularly good at blocking the pain receptors in the mouth.
