Marshmallow (Althaea officinalis) has a long history of use in traditional herbal medicine for urinary tract and bladder irritations. Historical texts from European and Middle Eastern herbal traditions describe the use of marshmallow root and leaf preparations for soothing mucous membranes, including those of the urinary tract. The primary rationale is that marshmallow contains mucilage, a gelatinous substance that can coat and soothe inflamed tissues. In cases of irritable bladder or mild urinary tract discomfort, marshmallow tea or extracts were believed to provide a demulcent (soothing) effect, potentially reducing irritation and pain.

Modern scientific studies directly investigating marshmallow’s effects on irritable bladder are limited. Most evidence remains anecdotal or based on extrapolation from its general demulcent properties. Some laboratory research suggests that mucilage-rich extracts can protect mucosal surfaces and may help reduce inflammation, but robust clinical trials are lacking. Reviews of herbal medicine acknowledge marshmallow as a traditional remedy for urinary and bladder irritation, often recommending it as an adjunct to other therapies rather than a primary treatment.

In summary, marshmallow’s use for irritable bladder is primarily supported by traditional practice, with limited scientific validation. The evidence is not strong enough for firm clinical recommendations, but its historical use and safety profile make it a common choice in herbal medicine for mild bladder discomfort.
