Rating (out of 5): 2

Plantago species, particularly Plantago major (common plantain) and Plantago lanceolata, have a long history of traditional use in treating various oral and mucosal conditions, including canker sores (aphthous ulcers). In traditional European and Asian herbal medicine, fresh leaves or extracts of Plantago have been used topically for their soothing, anti-inflammatory, and wound-healing properties. The mucilaginous compounds present in the leaves are believed to form a protective barrier over mucosal lesions, potentially reducing irritation and promoting healing. Additionally, Plantago contains bioactive compounds such as allantoin, aucubin, and flavonoids, which are thought to contribute to its anti-inflammatory and antimicrobial effects.

However, while these traditional uses are well documented in ethnobotanical literature, clinical evidence specifically evaluating Plantago for aphthous ulcers is limited. A few in vitro and animal studies suggest the plant’s extracts may promote wound healing and reduce inflammation, but rigorous human trials for canker sores are lacking. Therefore, while the traditional rationale is plausible and supported by some preclinical data, modern scientific validation remains insufficient. Most recommendations for Plantago in canker sore management are based on traditional usage rather than robust clinical research.
