Liver of blaspheming Jew,
Gall of goat, and slips of yew
Silver’d in the moon’s eclipse,
Nose of Turk, and Tartar’s lips,
Finger of birth-strangled babe
Ditch-deliver’d by a drab,
Make the gruel thick and slab.

– William Shakespeare

Macbeth, Act 4, Scene 1. The description of the ingredients used by the Witches for their sickening stew was meant to disturb and shock audiences. Here the Second Witch graphically details the various body parts they use to cast their evil spell.
