Eggs me on - I've got lots of recipes and ideas. Any particular type you're looking for?
I started using herbs on my family in 1992 and have hardly had to do anything else. They've kept people alive and healthy for many years, animals too. According to the Poison Control Center, there's thousands of calls every year regarding overdoses/reactions to tylenol/aspirin, but not a single one about herbs! What does that tell ya?
Plantain is easily identified, edible, there's nothing in my neck of the woods that looks enough like it to be mistaken for it. I've put handfuls into the blender with water and then soaked a cloth to use as a poultice. You can put that into the fridge for later use and of course the cold makes it even better. But I've also just picked a leaf, pinched off the stem and rolled it in my hands till it gets rather wet and put that on a bug bite, bee sting, welt, swelling - it works that well!
And it grows most everywhere. The plants in our horse pasture are huge compared to the lawn. B/c it's so common, you can find it on a moments notice just about anywhere there's a grassy spot so it's readily available, except in winter.
here's a link to a site with a good picture and info about it, with links to others.
