About marshmallow root
We’re all familiar with pink, fluffy, exceptionally moreish marshmallow sweets, aren’t we? But there’s little connection between those popular campfire staples and the wonderfully adaptable herb marshmallow root. Today’s marshmallow sweets may have evolved from an ancient Egyptian confection which did contain the root of the marshmallow plant, but that’s where the connection ends. Today, the marshmallow root has been replaced by gelatin in marshmallow sweets. And marshmallow root is purely a supplement. And yes, marshmallow root for dogs is a supplement too!
The thing that made those early sweets so appealing to early Egyptians was a key element of marshmallow root. It’s called mucilage. It’s that very thing that makes marshmallow root for dogs such a useful tool for healing any dog with a troubled gut.
Mucilage is indigestible fibre. It’s a sticky, gelatinous material that, as it travels through your dog’s gut, coats it with a protective layer. That protective layer soothes and heals the lining of the entire digestive tract.
Marshmallow root contains up to 35% mucilage. And, along with slippery elm and deglycyrrhised liquorice root, marshmallow root is one of a number of such mucilage herbs.
It’s also useful for dealing with urinary tract inflammation. In fact it’s beneficial for anywhere that involves surface inflammation or irritation of internal mucous membranes (mucosa).

Benefits of marshmallow root
When your dog suffers from inflammation in the digestive tract, it causes the lining of the gut to become more permeable than it was designed to be. The lining of your dog’s gut is the only thing stopping harmful bacteria, toxins and microscopic particles of undigested food entering the bloodstream and causing havoc throughout your dog’s body.
This is leaky gut syndrome, and it can make your best friend prone to all manner of chronic (long-term) inflammatory health conditions as a result of it. These conditions include allergies, arthritis, autoimmune disorders, cancer, diabetes, heart disease and inflammatory bowel disease (IBD).
Marshmallow root can help treat:
- IBD
- Urinary Tract Infections
- Nausea
- Vomiting
- Diarrhoea
- Respiratory problems

My dog has re-occurring calcium oxalate bladder stones. He has has meningomyelitis and is own 5 mg of prednisone, 50 mg of cyclosporine daily and 8 cc’s of cytosar monthly. I’ve tried to do research on drug interactions. I want to try and give him herbal supplements for the bladder stones but am wondering if the marshmallow root can cause any problems with his regular medications? His internal medicine specialist and neurologist are not very educated about the herbal supplements and I cannot get an appointment with a holistic vet and pet nutritionist for a month.
Thank you,
