I took a quick look after shooting off that last email (I have the
broad-leaved below as well as a narrow-leaved).  It is not just for small
cuts as it says in this article.  It is also for wounds that WON'T heal. 
I've seen pictures of what it can do.

Broad-leaved Plantain

Scientific Names: Plantago major
Other names: Bird's Meat, Common Plantain, Great Plantain, Rat-tail
Plantain, White Man's Foot
Family: Plantaginaceae

Evergreen perennial, spreading by seed, which cling to feet - it was taken
to the New World for herbal use and became known to North American Native
Peoples as "White Man's Footsteps" as it followed the new inhabitants
where they settled. Persists for many seasons, forming a rosette close to
the ground, so it avoids the sweep of mower blades. It is tolerant to
trampling, surviving on paths and driveways.

The leaves contain tannins and astringent chemicals which, when crushed,
make useful styptics for small cuts and an alternative to dock leaves for
nettle stings. Lotions can be used to sooth itchy, chapped skin, insect
bited and sore eyes. There are also internal medicinal uses where the
expectorant effect and the mucilage content of the plant ease inflamed
mucous membranes during bouts of coughs and bronchitis.

There is some evidence of antibacterial properties.
