Macbeth (iii) — Pluck a rooted sorrow

MACBETH
    [...]
    How does your patient, doctor?
DOCTOR
         Not so sick, my lord,
    As she is troubled with thick-coming fancies
    That keep her from her rest.
MACBETH
        Cure her of that.
    Canst thou not minister to a mind diseased,
    Pluck from the memory a rooted sorrow,
    Rize out the written troubles of the brain
    And with some sweet oblivious antidote
    Cleanse the stuffed bosom of that perilous stuff
    Which weighs upon the heart?
DOCTOR
        Therein the patient
    Must minister to himself.

—Shakespeare, Macbeth

(Act 5, Scene 3)
