Doctors Gallopots

A gallopot just for definition is like a pot that you put medicine or herbs in. So either this word is being used in an archaic way that we don't really recognize anymore. It doesn't even come up in most normal dictionaries of a gallopot being a servant or assistant that handles herbs and medicine because the word means the jar. Drought says, well we have to go find him and they say no. What are you even doing here? And he says, wellwe're physicians gallopots. We're here to pick up some herbs from the graves."
