Poison, I see, hath been his timeless end:
O churl! drunk all, and left no friendly drop
To help me after? I will kiss thy lips;
Haply some poison yet doth hang on them,
To make die with a restorative.
[Kisses him] Thy lips are warm.
– William Shakespeare
Romeo and Juliet, Act 5, Scene 3. Juliet awakens in the tomb and discovers Romeo dead. Overcome by sorrow, she kisses his lips in the hope that the poison he took will take her life too. Deciding that she cannot live without him, she sees the poison as a "restorative" – a medicine that will heal her by allowing her to be with her love in death. This fits in with the play’s theme of the relationship between and inseparability of good and evil, in this case the poison also containing the cure.
