Rating (out of 5): 2

Marshmallow (Althaea officinalis) has a long history of traditional use for the treatment of external ulcerations, wounds, and skin irritations. The plant's mucilaginous root has been valued in folk medicine for its soothing and protective properties when applied topically. Ancient Greek, Roman, and later European herbal texts describe the application of marshmallow poultices or ointments to ulcers, burns, and inflamed skin. The primary rationale behind its use stems from the high mucilage content, which forms a viscous, protective barrier over the affected area, potentially reducing irritation and promoting moisture retention—factors believed to aid the healing process.

While the traditional use is well documented, scientific validation is limited. Some in vitro and animal studies suggest that marshmallow extracts may exhibit anti-inflammatory and wound-healing effects, likely due to the polysaccharides and flavonoids present in the plant. However, robust clinical trials in humans are lacking, and most modern evidence remains anecdotal or based on traditional practice rather than rigorous scientific scrutiny.

In summary, the use of marshmallow for external ulcerations is primarily supported by traditional herbal medicine, with limited scientific evidence to validate its efficacy. Its soothing, emollient action is the basis for its continued inclusion in some topical preparations aimed at relieving minor skin irritations and ulcerations.
