Although maybe a cauldron full of the ingrediants (or similar) minus the heart is necessary to generate a message that could be accessible from across realms.

But i get the feeling that the DC itself predates even Merlin. Yeah, I think Hook simply got the ingredients when Emma couldn't find him for that brief period of time and Dark Rumple knows the ingredients.
