Demulcent agents work by coating mucous membranes, reducing irritation, and promoting healing. They are particularly useful for conditions affecting the digestive, respiratory, or urinary systems, where inflammation or dryness is present. Marshmallow root (Althaea officinalis) is a classic demulcent, soothing the throat, stomach, and urinary tract. Licorice root (Glycyrrhiza glabra), especially in its deglycyrrhizinated form (DGL), helps protect and heal the stomach lining. Plantain leaf (Plantago spp.) is also a gentle demulcent that supports respiratory and digestive tract health. Demulcent herbs provide natural relief for irritation and inflammation, fostering comfort and healing in sensitive tissues.
