Botanical Description

A tall perennial 60–120 cm with soft velvety, lobed grey-green leaves, pale pink five-petaled flowers, and a thick, pale taproot rich in mucilage. The root and leaves are the medicinal parts.

Also known as: Marsh Mallow

Historical Background

Marshmallow root has been a soothing demulcent since Greek and Roman times, and gave its name to the confection (originally a medicinal pâte de guimauve made from the root). It is a cornerstone of Western mucilaginous herbalism for the throat, stomach, and skin.

Earliest recorded uses: Dioscorides and Pliny; medieval European herbals for irritation and wounds.

Cultural significance: The original 'marshmallow' candy was a French confection of marshmallow root mucilage and sugar, prescribed for sore throats — the plant's medicinal origin survives only in the candy's name.

Modern Evidence

Marshmallow root is a classic demulcent; its mucilage coats mucous membranes. Clinical trials are few and small, with limited evidence for cough, dry mouth, and skin irritation. It is best understood as a soothing comfort herb, not a treatment for disease.
