Plantain leaves are traditionally crushed and applied as a poultice to insect bites to help soothe itching and irritation.
Here, plantain means broadleaf plantain, Plantago major, not the starchy banana relative also called plantain. The low-growing perennial forms a rosette of broad, prominently veined leaves and commonly thrives in lawns, paths, fields, and compacted soil.
Folk remedies use freshly bruised or crushed leaves directly on bites, stings, minor sores, and irritated skin. Plantain contains compounds including allantoin, aucubin, flavonoids, and ursolic acid, although traditional use should not be confused with strong clinical proof. A severe reaction, spreading redness, breathing difficulty, or signs of infection needs medical attention.
The name can also cover other Plantago species, particularly ribwort plantain, Plantago lanceolata, which has narrower leaves and similar traditional uses. Witch hazel and aloe vera are also popular skin remedies, but they are not the specific crushed-leaf plantain poultice described here. The stored answer is therefore the standard quiz answer.
