The poultice herb growing in your lawn, with real topical evidence and a genuinely useful sting remedy. — Plantago major, P. lanceolata
remedyPlantain (Plantago major, P. lanceolata) is the plant most people walk past daily. It is one of the most abundant wild medicinals here, and its evidence is concentrated where it is most useful: topically, on skin.
What it is good for. Plantain leaf is astringent and soothing. The traditional uses — a crushed leaf poultice on an insect bite, a graze, a nettle sting or a small area of irritated skin — are supported by mechanistic plausibility and by a small clinical literature. It is the single best field remedy to know for a sting when you are out walking.
Internal use is traditional for cough and for gut irritation, with weaker evidence — plantain is a mucilage-containing leaf, so this is plausible but not trial-supported to any useful degree.
The identification point is the one that matters. Plantain is easy to identify once you know it, and it grows in lawns, path edges and disturbed ground. But it grows exactly where contamination lands — roadsides, sprayed verges, dog-walking ground. Harvesting plantain from a verge is harvesting whatever that verge has been exposed to.
Psyllium, worth knowing, is a different species of the same genus and is the form with real evidence for constipation — a useful reminder that related plants are not interchangeable.
Psyllium fiber effectively improves conventional and alternative lipids markers, potentially delaying the process of atherosclerosis-associated CVD risk in those with or without hypercholesterolemia.PubMed 30239559 ↗
Honey probably relieves cough symptoms to a greater extent than no treatment, diphenhydramine, and placebo, but may make little or no difference compared to dextromethorphan.PubMed 29633783 ↗

Fresh leaf poultice — crush or chew a clean leaf and apply to a sting, bite or graze. The classic field remedy.
Salve — plantain infused in oil with beeswax for bites and irritated skin.
Tea — 1-2 teaspoons dried leaf per cup; a mild astringent and mucilaginous tea.
Juice — crushed fresh leaf juice applied to the skin.
Note: the psyllium used for constipation is Plantago ovata, a different species. Plantain leaf is not a bulk laxative.
