Historical or traditional use: Marshmallow (not to be confused with confectionery marshmallows, which are a product of the modern food industry) has long been used to treat coughs and sore throats.1 Because of its high mucilage content, this plant is soothing and healing to inflamed mucous membranes. Additionally, it was used to treat chapped skin, chilblains, and even minor wounds.

Active constituents: The active constituents in marshmallow are large carbohydrate (sugar) molecules which make up mucilage. This smooth, slippery substance can soothe and protect irritated mucous membranes. Although marshmallow has primarily been used for the respiratory and digestive tracts, its high mucilage content may also provide some relief for the urinary tract and skin.2

How much should I take? Marshmallow can be made into a hot or cold water tea. Make a tea by adding roots and/or leaves and letting it steep. Drink three to five cups a day. Herbal extracts in capsules and tablets providing 5-6 grams of marshmallow per day can also be used, or it may be taken as a tincture in the amount of 5-15 ml, three times daily.

Are there any side effects or interactions? Marshmallow is very safe. There have been extremely rare reports of allergic reactions.
