Not my fault I don't know what your world's invented yet.

[She's the one who thought it might be a poultice. He's not entirely sure what a poultice is.]

I don't know what it does even if it's the real stuff. These names are impenetrable gibberish, and sometimes you've got brand names that tell you even less than the generic. And all the instructions say are like, 'take twice daily with meal', but not if you're nursing, pregnant, or may become pregnant, because then they might deform your quantum future baby somehow. It's a whole bottle of mystery to me.
