Marshmallow Root in History & Tradition
Soft, silky, and soothing, marshmallow root( Althaea officinalis ) is the plant that inspired the original marshmallow sweet. And it makes sense - this herb is all about softness. Its velvety leaves, delicate flowers, and gooey, mucilage-rich roots are nature’s answer to irritation and inflammation, wrapping everything they touch in a protective, cooling hug.
The ancients adored marshmallow. Egyptian healers, Greek physicians, Roman herbalists, and Middle Eastern traditions all celebrated its ability to calm sore throats, soothe coughs, and ease digestive upset. Pliny himself proclaimed that “ whosoever shall take a spoonful of mallows shall that day be free from all diseases. ” (A bold claim, but it shows how highly it was prized!)
Culpeper praised it in 1653 for helping with “ all hot and sharp diseases, ” while Dr. Ellingwood, writing in 1919, noted its soothing effect on the intestines and bladder. From cough syrups to gut tonics, marshmallow has always been a go-to herb of comfort.
Why herbalists still love it
The magic of marshmallow lies in its mucilage - a gel-like substance released when steeped in water. This makes it:
- Demulcent – coating and soothing sore throats, dry coughs, and irritated lungs.
- Gut-friendly – easing acid reflux, ulcers, IBS, and inflammation in the GI tract.
- Cooling + moistening – perfect for hot, dry, irritated conditions inside or out.
- Diuretic – gently supporting kidney and bladder health.
Interestingly, the root is richer in mucilage, making it more useful for gut health, while the leaf is often chosen for respiratory complaints.
From food to pharmacy
Marshmallow wasn’t always 'just' a herb. For centuries it was eaten as food - high in calcium and rich in trace minerals like magnesium, selenium, and iron. Even today, some herbal traditions still treat it as both food and medicine.
And of course, it gave us the marshmallow sweet - though modern marshmallows are sadly more sugar than plant!
