What is lady Macbeth's urging of Macbeth?

Lady Macbeth was an accessory and an accomplice to her husband in the murder of King Duncan I [d. August 14, 1040]. It was in fact she who came up with the plan to help Macbeth [d. August 15, 1057] carry out the killing of his sovereign and the two royal guards without any blunders. She planned to get the guards to drink too much of drugged drinks. They then would be incapable of defending their ruler. Neither would they be capable of defending themselves when Macbeth turned the daggers on them as well.
