How does mallow function as a mild laxative within the digestive tract?

Due to the bulk provided by the mucilage softening stool

Mallow addresses digestive complaints through multiple mechanisms, one of which is functioning as a mild laxative. This effect is not achieved through harsh stimulation of intestinal muscles, like some stronger herbal laxatives. Instead, it relies on the physical properties of the high mucilage content. Once ingested, the mucilage adds significant bulk to the material moving through the colon. This added bulk helps to retain moisture within the intestinal contents, thereby softening the stool. This softer, bulkier stool promotes a smoother and easier passage through the colon, offering relief from mild constipation without causing aggressive cramping or irritation.
