Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Marshmallow root (Althaea officinalis) has a long history of use in traditional herbal medicine, especially for soothing mucous membranes throughout the body, including the urinary tract. Historically, marshmallow root was employed by herbalists and practitioners of traditional European medicine as a demulcent—a substance that forms a soothing film over mucous membranes. This property made it a popular remedy for conditions involving irritation or inflammation, including ulceration of the bladder (also referred to as interstitial cystitis or similar conditions in traditional texts). The root contains mucilage, a polysaccharide-rich substance that can coat and protect irritated tissues, potentially reducing discomfort.
While modern scientific studies specifically addressing marshmallow root for bladder ulcers are limited, some in vitro and animal studies suggest marshmallow root extracts can reduce inflammation and form a protective layer over mucosal surfaces, supporting its traditional use. However, clinical trials in humans with ulcerative bladder conditions are lacking, and thus, the evidence remains largely anecdotal and rooted in tradition rather than robust scientific validation. Overall, marshmallow root continues to be used by some herbalists for urinary tract irritation, but its effectiveness for bladder ulceration is mainly supported by traditional use rather than strong clinical evidence.
