We don't know the mechanics so we go with what the show gives us in simplest forms. Example: Potioncraft is somewhat magical, somewhat mundane. It isn't necessarily always magical.

When George said he cursed her, I took that to mean symbolically. He saw his wife's inability to have a child as a curse, so he poisoned Snow. (I don't think magic was involved at all.) Or at the very least, magic can afflict things that can't be solved by true love'd kiss. Rumple could break Regina's fingers one by one. Doesn't mean she can solve that by kissing Henry, even if Rumple called it the curse of fractured fingers.

The water works because it has restorative powers.
