© Steven FosterHow It Works
Mucilage, made up of large carbohydrate (sugar) molecules, is thought to be the active constituent in marshmallow. This smooth, slippery substance is believed to soothe and protect irritated mucous membranes. Marshmallow has primarily been used as a traditional herbal soothing agent for conditions of the respiratory and digestive tracts.2
How to Use It
The German Commission E monograph suggests 1 1/4 teaspoon (6 grams) of the root per day.3 Marshmallow can be made into a hot or cold water tea. Often 23 teaspoons (1015 grams) of the root and/or leaves are used per cup (250 ml) of water. Generally, a full day’s amount is steeped overnight when making a cold water tea, 69 teaspoons (3045 grams) per three cups (750 ml) of water, or for fifteen to twenty minutes in hot water. Drink three to five cups (7501250 ml) a day. Since the plant is so gooey, it does not combine well with other plants. Nevertheless, it can be found in some herbal cough syrups. Herbal extracts in capsules and tablets providing 56 grams of marshmallow per day can also be used, or it may be taken as a tincture—13 teaspoons (515 ml) three times daily.
