Rating (out of 5): 2

Marshmallow (Althaea officinalis) has a long history of traditional use for soothing irritation in the digestive tract, including duodenal ulcers. The root of the marshmallow plant contains mucilage, a gelatinous substance that is believed to coat and protect mucous membranes. Traditional European and Middle Eastern herbal medicine commonly recommended marshmallow root preparations as a demulcent—a substance that relieves irritation of the mucous membranes by forming a protective film. For duodenal ulcers, this demulcent action was thought to shield the ulcerated tissue from stomach acid and digestive enzymes, potentially promoting healing and reducing pain.

Scientific studies on marshmallow's efficacy for duodenal ulcers are limited and mostly preclinical. Some in vitro and animal studies show that marshmallow extracts can protect gastric tissue from irritants and promote epithelial regeneration, likely due to the mucilage content. However, there are very few high-quality human clinical trials specifically addressing its effectiveness for duodenal ulcers. The evidence remains primarily anecdotal and rooted in traditional practice.

In summary, while marshmallow has a strong traditional basis for use as a soothing agent in gastrointestinal complaints and some plausible preclinical support, robust scientific validation for its use specifically in duodenal ulcer treatment is lacking. Its safety profile is generally favorable, especially when used as a tea or tincture, but it should not replace standard medical therapy.
