Marshmallows And Your Mucous Membranes
Ever wondered where marshmallows got their name? From the Marshmallow plant, Althaea officinalis, of course…
“This weed is perhaps amongst the most valuable of plants that ever grew… its operation in all cases is so quick that it is hardly to be believed” (A. Lawson, 1882, pp. 282-283).
Digestive discomfort comes to us all on occasion. With the equivalent length of a two-storey building running from your mouth to your anus (25 feet long approx.), the GI tract is, fundamentally, a long tube whose inner surface is lined with mucous membranes protecting us from the world outside (Hull, 2024). Quite the responsibility, here we will learn how the marshmallow plant helps protect those mucous membranes and soothe an irritated digestive system.
“Used for more than 2000 years in Europe both internally and externally" (Leung & Foster, 1996, pg. 30).
Its primary constituent is mucilage. A long-chain polysaccharide, mucilage is hydrophilic and absorbs water to form a viscous, indigestible gel that coats the surface of mucous membranes (Pengelly, 2021). In herbal medicine, this is known as a demulcent action, meaning a substance that soothes and relieves irritation on inflamed surfaces (McIntyre, 2019). The indigestibility of mucilage means it physically coats the membrane as a barrier. Just like a plaster, this barrier protects the irritated mucous membrane beneath, leaving it to heal without further irritation (Hoffman, 2003).
Important: Irritation of the GI tract can present with many symptoms, Marshmallow root works well with Gastro-oesophegel reflux, peptic ulcers and gastritis. It is not a substitute for medical treatment. Do not consume alongside prescribed medications (Bone, 2007).

Below is my recipe for homemade marshmallows. Not only do they taste fantastic, they also support gut health. Mix up the flavours and toppings (I used cinnamon) but always use dried marshmallow root as your base. Happy whipping!
Ingredients
20g of dried marshmallow root (I buy mine from Organic Herb Trading Company)
80ml water
5 egg whites
200g maple syrup
40g powdered gelatin
1tsp vanilla extract
Cinnamon to taste
Method
- Cold infusion: Soak marshmallow root in water for at least 1 hour, preferably overnight. Strain
- Bloom gelatin: Sprinkle gelatin into the strained infusion and leave to bloom for 5 minutes.
- Whip egg whites: on a medium to high speed until firm peaks form.
- Heat syrup: Combine the maple syrup with the bloomed gelatin/infusion mix in a saucepan. Stir until gently boiling. Remove from heat immediately.
- Combine: Slowly pour the hot syrup into the egg whites whilst mixing on a medium speed. Add vanilla extract and whip on high for 10 minutes
- Set and store: Pour into a parchment-lined dish and refrigerate until firm.
Sourcing sustainability: While Althaea officinalis is not endangered, it is on the decline (Brab, 2024). Malva sylvestris or common mallow is an abundant and effective alternative (Bruton-Seal & Seal, 2008)
