Thedas is the continent, yeah. It's very medieval. The woman I was talking with up above got a supply of Thedosian herbs and is apparently growing them now, but I've not seen any around except for deep mushrooms. For these potions, I substituted a few things.
I'll give you a good supply, for all those knee scrapes and potentially falling out of trees mishaps. And, really, yeah - I wish something like that could fix objects. Force magic is kind of like telekinesis, which could maybe fuse things but it's not my specialty.
