Whosoever shall take a spoonful of the Mallows shall that day be free from all diseases that may come to him.
I love single herbs that seemingly do everything.
Their complexity could inspire a lifetime of devotion to learning the intricate ways they could be used for food and medicine, as well as the ways they support their habitat and the gifts they bring the earth. Single herbs that can be used in a variety of ways are called "polycrest herbs." And the marshmallow herb is certainly a polycrest.
Marshmallow is known primarily as a demulcent that is specific to the mucous membrane tissues. Because of its thick and slimy brew you can easily imagine that it is used to soothe and coat irritated tissues. Mouth ulcers, sore throats, peptic ulcers, and inflamed intestines all get relief from this gooey brew.
Marshmallow herb works in complex ways. It can even be used as a lubricating demulcent for the lungs and for the urinary tract, even though it never comes in direct contact with these surfaces. Herbalist jim mcdonald explains:
Though it makes sense that demulcents coat tissues, the physical mucilage is actually very poorly absorbed by the body, and certainly isn’t traveling through the blood to the kidneys. Rather, the ingestion of mucilage seems to promote a systemic moistening of tissues throughout the body, with some demulcents being more specific to particular organ systems.
According to a survey published by Paul Bergner, marshmallow is one of the top 20 herbs used by herbalists in the US.
Like many of the herbs still in use today, marshmallow has a long history of use, going back at least 2,000 years, though most probably even more than this. Most herbalists use marshmallow root for medicine today, but the leaves and flowers are also very viable.
The genus name for marshmallow herb is derived from the Greek word altho, which means to cure. This gives us a great indication of how highly regarded this plant was in ancient times.
Herbalist Nicholas Culpeper relates this story about a mallow’s ability to heal:
"You may remember that not long since there was a raging disease called the bloody flux; the College of Physicians not knowing what to make of it, called it The Plague in the Guts, for their wits were at ne plus ultra about it. My son was taken with the same disease; myself being in the country, was sent for; the only thing I gave him was Mallow bruised and boiled both in milk and drink; in two days it cured him, and I have here to shew my thankfulness to God in communicating it to his creatures, leaving it to posterity."
Marshmallow herb is an amazing topical treatment for wounds and burns. In the past it was called mortification root because of its ability to prevent gangrene.
marshmallow root is very useful in the form of poultice, to discuss
painful, inflammatory tumors, and swellings of every kind, whether the
consequence of wounds, bruises, burns, scalds, or poisons; and has, when
thus applied, had a happy effect in preventing the occurrence of
gangrene. The infusion or decoction may be freely administered.
- King’s American Dispensary, 1898
Besides the roots, marshmallow leaves are also used as a fomentation to soothe rashes and other irritations of the skin.
Marshmallow and other members of the Malvaceae family were historically eaten as foods. Marshmallow roots are especially high in nutrients, and the young leaves and flowers are quite tasty in salads.

Marshmallow roots are high in polysaccharides and starches. By using a cold infusion you extract mainly the mucilaginous polysaccharides. If you simmer the root you also extract the starches in the plant (which is okay; the cold infusion is considered to be a purer extract of the mucilage.)
Alcohol above 20% percent will break down the polysaccharides. Some herbalists make a decoction of the root and then preserve it with 20% alcohol.
