Marshmallow Root
Althaea officinalis
Select sizeThe plant
Marshmallow is a pale-flowered plant of damp ground. Its dried root is used in herbal drinks.
What's in it
Mucilage is the slippery, gel-like material produced when the root meets water. It is made from long chains of natural sugar units.
Mucilage polysaccharides
Up to a third of the dried root. The defining component.
Pectin
Contributing to the gel-forming behaviour.
Starch
A large share of the remaining dry weight.
Flavonoids
Present in small amounts.
How it works
Soothing contact: The root’s mucilage forms a soft coating when mixed with water. This helps explain its traditional use for an irritated mouth or throat and associated dry cough. Digestive comfort: Herbalists also use it for mild stomach discomfort. Demulcent is the herbal word for this soothing, coating quality.
In the tradition
A longstanding European soothing herb.
The original marshmallow confection was associated with this plant.
