Marshmallow Root (Althaea officinalis)

Dried root of Althaea officinalis, Marshmallow Root, the classic mucilaginous demulcent of Western herbalism.

What is Marshmallow Root?

Marshmallow is a tall perennial plant native to marshy areas of Europe, Western Asia, and North Africa (giving rise to the "marshmallow" common name). The root is rich in mucilage - long-chain polysaccharides that form a viscous, soothing gel when extracted in water. Historical confectionery use of the root predates modern marshmallows; the modern candy preserves the name but no longer contains the plant.

How to Use Marshmallow Root - Cold Infusion

The traditional preparation for marshmallow is a cold infusion rather than hot tea. Heat denatures some of the mucilage; cold water extracts it more completely. To prepare: place 1-2 tablespoons of dried root in a jar, cover with cold water, seal, and refrigerate for 4-8 hours. Strain. The resulting liquid is mildly slippery and demulcent. Drink as needed throughout the day.
