Juliet
[Kisses him]
A restorative is a medicine or liquor which would restore Juliet and bring her back to consciousness. In other words, it would do the opposite of "to make me die." In one sense, the kiss is her restorative, and the drops of poison, its opposite. In another sense, in dying, Juliet is restored to Romeo.
