Was just on a cool site here. Rabbit Tobacco! It's all about a Silvery leafed plant that is fairly common all over the world, apparently, although I haven't checked the map yet. Anyway, i thought you might want to check it out for yourself. You can use it for all sorts of medicinal things and it's free for the gathering!
It was written and posted last year, but the information certainly is still valuable. Here is the post:

BTW: I am not quite sure if this is something I can't do on Steemit, so if not, sorry.
