Medicinal Actions & Uses

Useful whenever a soothing effect is needed, marshmallow protects and soothes the mucous membranes. The root counters excess stomach acid, peptic ulceration, and gastritis. Marshmallow is also mildly laxative and beneficial for many intestinal problems, including regional ileitis, colitis, diverticulitis, and irritable bowel syndrome.

The leaves treat cystitis and frequent urination. Marshmallow’s demulcent qualities bring relief to dry coughs, bronchial asthma, chronic bronchitis, and pleurisy. The flowers are applied to help soothe inflamed skin. The root is used in an ointment for boils and abscesses, and in a mouthwash for inflammation. The peeled root may be given as a chew stick to teething babies.
