Cold-infused mucilage for irritated digestion
Moderate evidenceHerbs in this remedy
About this remedy
Marshmallow root contains 25–35% mucilage — long-chain polysaccharides that form a slick, soothing gel when steeped in cool water. This gel coats and calms irritated mucous membranes throughout the digestive tract and throat. Cold infusion preserves the mucilage best, as heat breaks the polysaccharides down. Traditionally used for gastritis, reflux, dry coughs, and general gut irritation — one of the gentlest demulcents in Western herbalism.
Preparation
Add 1 tablespoon dried marshmallow root to a jar with 2 cups room-temperature water. Cover and let sit 4–8 hours (overnight is ideal). Strain through a fine sieve — the liquid will be clear and slightly slimy.
Dosage
½ cup, 2–3 times daily between meals. Can be sipped warm or cool.
Cautions
May slow the absorption of medications taken at the same time — separate by at least 2 hours. Generally very well tolerated; safe for long-term use.
