Evidence-Based Benefits

  • Mucosal protection — marshmallow root mucilage forms a bioadhesive gel that adheres to epithelial surfaces, providing sustained protection against acid and irritants (Al-Snafi, 2013)
  • Anti-inflammatory effects — aqueous extracts of marshmallow root inhibited complement activation and reduced inflammatory mediators in vitro (Scheffer et al., 2005)
  • GERD symptom relief — a 2017 pilot study found a herbal formula containing marshmallow root significantly reduced heartburn symptoms compared to placebo (Tewari et al., 2017)
  • Antitussive activity — EMA monograph recognizes marshmallow root as a traditional herbal medicine for dry coughs and mild gastric complaints based on long-standing use

What the Research Says

Marshmallow root has a long history of traditional use validated by European pharmacopoeias and the EMA (European Medicines Agency), which grants it "traditional use" status for dry cough and mild gastric complaints. Modern research confirms its mucilage content, anti-inflammatory properties, and mucosal bioadhesion. Clinical trial evidence is limited to small studies and combination products. Its primary role remains as a gentle, well-tolerated demulcent for GI and respiratory mucosal irritation.
