Roots and leaves
However, while concoctions of all parts of the Marsh mallow plant have been used as medicine, a traditional use of the plant can be found in old recipes: Stems of marsh mallow were peeled to reveal the soft and spongy pith. This pith was boiled in sugar syrup and dried to produced a soft, chewy confection. Commercial marshmallows are a late-nineteenth-century innovation, which was a development of a well used recipe from the old days using the Marsh mallow plant itself.
Because it coats the lining of the stomach, marshmallow may interfere with the absorption of other drugs or herbs. For this reason, it is important to take marshmallow several hours before or after taking other herbs or medications.
