Buckhorn Plantain (Plantago lanceolata) has a long history of traditional use in herbal medicine, particularly in Europe, for supporting skin health and treating minor wounds, insect bites, and inflammatory skin conditions such as dermatitis. Historical records and ethnobotanical surveys frequently cite the use of plantain leaves as poultices or topical preparations to soothe irritated or inflamed skin. The rationale for its use traditionally is based on its mucilage content, which forms a soothing layer when applied to the skin, and on anecdotal observations of its anti-inflammatory and wound-healing effects.

From a scientific standpoint, there is some preliminary evidence suggesting that extracts of Plantago lanceolata possess anti-inflammatory, antimicrobial, and wound-healing properties, which could theoretically benefit dermatitis. Certain laboratory studies have identified bioactive compounds such as aucubin and acteoside, which may contribute to these effects. However, robust clinical trials specifically evaluating its effectiveness in dermatitis are lacking. Thus, while the traditional use is well documented, and there are plausible mechanisms supported by laboratory research, the overall evidence remains limited and primarily traditional rather than strictly scientific.
