Eye of newt and toe of frog,
Wool of bat and tongue of dog.
Adder’s fork, and blind-worm’s sting,
Lizard’s leg, and howlet’s wing,
For a charm of powerful trouble,
Like a hell-broth boil and bubble.

– William Shakespeare

Macbeth, Act 4, Scene 1. As the Second Witch chants, we learn more about the revolting ingredients for the spell that the Witches are cooking up in their cauldron of wickedness.
