Marshmallow Root

Althaea officinalis

Mucilage-rich root that soothes the gut and throat lining

About Marshmallow Root

Marshmallow root is one of the most prized demulcent herbs in Western herbalism. Its roots contain 25–35% mucilage — long-chain polysaccharides that swell into a slick, soothing gel when steeped in water. This gel coats and calms irritated mucous membranes throughout the digestive and respiratory tracts. Used since ancient Greek and Egyptian times for sore throats, dry coughs, gastritis, and reflux, and the original namesake of the marshmallow confection (which was once made from the root's sap). Cold infusion preserves the mucilage best, as high heat breaks the polysaccharide chains down.

Key benefits

  • Coats and soothes irritated gut and throat lining
  • Traditionally used for gastritis, reflux, and dry cough
  • Gentle, well-tolerated, and safe for long-term use
  • May support healthy mucous membrane integrity

How to use

Cold infusion: soak 1 tbsp dried root in 2 cups room-temperature water for 4–8 hours (overnight). Strain — the liquid will be slightly slimy. Drink ½ cup 2–3 times daily between meals. Also available as powder and capsules.

Did you know?

The original marshmallow candy was made by boiling marshmallow root sap with sugar and egg whites — the modern fluffy version uses gelatin and contains no actual marshmallow plant. Ancient Egyptians reserved it as a delicacy for pharaohs and gods.
