Used to Banish an Evil Ghost, To Send An Evil Ghost to Judgment is an entry in the Halliwell Family's Book of Shadows.
Prue Halliwell found the entry in the Book of Shadows after her sister Phoebe witnessed an evil spirit, Jackson Ward possess a human body in order to escape Alcatraz Prison. Rather than uses this potion however, banishing Jackson Ward required using another potion in the Book entitled To Vanquish a Ghost and Return Him to His Rest. The entry read:
To Send An Evil Ghost to Judgment
To render this potion, the witch who is to
conduct the ritual must take a fearless
inventory of that which she finds most foul.
She must plumb the depths of her resources
to concoct a combination of herbs and roots
that are, to her own nose, the most grotesque
and repugnant combination of odors.
These components, which are unique to the
witch conducting the ritual must be boiled in
a cauldron until they have become one with
each other, and must then be combined with
the mandrake root - which must be cut to
resemble the broken bodies of the dead.
