What specific action describes mucilage creating a protective film over irritated mucous membranes throughout the body?

Demulcent

The term demulcent describes a substance that functions by forming a protective, soothing, and relatively inert film or coating over irritated surfaces, particularly mucous membranes. In the context of mallow, the mucilage that forms a gel upon hydration is responsible for this action. When ingested, this gelatinous coating adheres to the internal lining of the throat, esophagus, stomach, and intestines. This physical barrier shields the inflamed or dry tissues from further irritation caused by normal body processes or environmental factors, thereby providing relief from dryness and inflammation. While mallow also exhibits emollient and expectorant qualities, its fundamental role in calming irritated linings is precisely defined by its demulcent capacity.
