What are the ingredients in Witches Brew?

Answer 1

"WITCH'S BREW FOR CLAIRVOYANCE
Into a cauldron of boiling water, add a handful each of shredded
laurel leaves, cinquefoil, and mugwort (3 herbs that have long been
associated with the arts of divination and prophecy.) Cover with a
lid, and boil for 13 minutes. Lift the lid of the cauldron and deeply
inhale the vapors of the bubbling brew 3 times. Take a normal breath
of air, and then once again deeply inhale the vapors 3 times. Repeat
this for 3 minutes, and if you have allowed yourself to properly enter
a psychic state, you may begin to receive prophetic visions, either in
the form of pictures or symbols, or perhaps in a combination of the
two."
