In answer to the question you asked me in the thread in C&R - If I had tried hipocras before...
Had to look up what Hippocras was...
So in answer to your question, kind of sort of, but not exactly.
I’ve had glogg and gluhwein before, wich are basically the same thing except that glogg is made with akvavit plus rasins while gluhwein has no rasins and uses red wine. From the description of typical hippocras ingredients, it sounds like it too is pretty much the same thing as glogg and gluhwein (except that hippocras can be made with either white or red wine it seems).
Damn, now I want to out and get a bottle of akvavit...
