Traditional Uses & Folklore
A name that means "to heal"
The genus name Althaea comes from the Greek althaino, "to heal." Ancient Greek and Roman physicians used mallow leaves for coughs, sore throats and irritated skin, and Romans even ate them as a vegetable. The "marsh" in its name is literal: the plant loves wet, salty marshland.
A soother for the throat
In European folk medicine, a warm tea of marshmallow leaf was a classic remedy for a scratchy, hoarse throat and a dry, tickly cough. Its slippery texture coats as it goes down, which made it a favorite for anyone who used their voice all day.
Leaves on the skin
Herbalists have long softened fresh marshmallow leaves in warm water and laid them on irritated, inflamed skin as a soothing poultice. The same cooling, moistening quality made the leaf a gentle addition to baths and washes.
The scienceWhat Modern Research Is Exploring
Research on marshmallow focuses on its mucilage and how it coats and soothes. Here's what researchers are looking at:
- Throat and cough. European regulators recognize marshmallow leaf's long traditional use for soothing an irritated mouth and throat and a dry cough.
- Soothing tissues. Lab studies have explored how marshmallow's mucilage forms a protective, soothing layer over irritated tissue.
- Skin. Marshmallow extracts have been studied for their soothing, moisturizing effect on irritated skin.

Sip mindfullySafety & Who Should Check First
Marshmallow leaf is generally considered very gentle in tea-sized amounts. 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.
