Marshmallow root comes from the marshmallow plant and looks like a brown, fibrous husk. The flowers, roots, and leaves of the marshmallow plant are edible. The medicinal properties of marshmallow root come from the mucilage, or sap-like substance, that the plant produces. The mucilage of the plant contains antioxidants, and research suggests that it forms a coating over the skin and the digestive tract. By doing this, it may help with skin irritation and digestive issues, such as ulcers. Marshmallows can also help with: • Cough and cold • Irritation • Wound healing • Skin • Pain relief • Diuretic • Digestion • Digestive tract
