Marshmallow root makes a great tea - just add two teaspoons of root to a cup of boiling water. The longer it sits, the thicker it becomes so enjoy it when it's hot and ready. Blends well with lavender, rose, and other botanical tea. You can also use marshmallow root for cooking; in fact, the root is the origin of the marshmallow candy first made by the ancient Egyptians. The gel-like mucilage is thought to soothe sore throats, gastrointestinal inflammation, and stomach ulcers, and even work as a laxative, among other qualities.
