Marshmallow Root
Marshmallow root is the original marshmallow, the gooey root sap that was whipped into candy long before gelatin took over. It's even richer in mucilage than the leaf, which makes it herbalism's go-to demulcent for the gut, traditionally used to coat, soothe and hydrate the digestive tract and support a healthy gut lining. Herbalists also reach for it to bring deep moisture to dry, irritated tissues all over the body, from the throat to the most delicate places. Slippery, soothing and seriously underrated.

Traditional Uses & Folklore
The original marshmallow
Ancient Egyptians are said to have mixed marshmallow root sap with honey into a sweet reserved for the gods and royalty. In 19th-century France, confectioners whipped the root's gooey sap with sugar and egg whites into pâte de guimauve, the first modern marshmallow. Today's candy swaps the root for gelatin, but the name stuck.
The cold infusion
The root holds even more mucilage than the leaf. Herbalists traditionally steep it in cold water overnight to draw out that silky gel without heat. The thick, soothing drink was a classic remedy for heartburn, an irritated stomach and a dry cough.
Moisture for the body's softest places
Marshmallow root has long been used as a demulcent, a herb that coats and moistens irritated tissue. Herbalists reach for it to soothe the digestive tract and the urinary tract, and as a gentle, hydrating herb for the body's most delicate tissues.
The scienceWhat Modern Research Is Exploring
Research on marshmallow root focuses on its mucilage and how it coats and soothes. Here's what researchers are looking at:
- Throat and cough. European regulators recognize marshmallow root's long traditional use for soothing dry coughs and an irritated mouth and throat.
- Gut lining. Lab studies have explored how marshmallow root's polysaccharides interact with the cells that line the body's soft tissues and support their repair.
- Digestion. Researchers have looked at marshmallow root's traditional use for heartburn and an irritated stomach, often in herbal combinations.

Sip mindfullySafety & Who Should Check First
Marshmallow root is generally considered very gentle. A few things to keep in mind:
- Medication timing. Marshmallow's mucilage coats the digestive tract and may slow how your body absorbs medications. Take medications an hour before or a few hours after.
- Blood sugar. Marshmallow may influence blood sugar. Check with your healthcare provider if you take medication for diabetes.
- Pregnancy. Check with your healthcare provider before using marshmallow regularly if you're pregnant, trying to conceive, or breastfeeding.
- Surgery. Pause herbal teas about two weeks before a scheduled surgery.
