To inflict hallucinations
Warning: the herbs in this spell are poisonous and hallucinogenic. Handle with care, wear gloves and make sure the room is well ventilated. You might want to wear something over your mouth. Also these plants may or may not be legal to possess where you live.
You will need:
Poppet of your victim with a piece of them (piece of their hair for example)
Crossroads dirt
Ground belladonna
Ground mandrake
Ground henbane
Something to boil water in
Boil the water (a cauldron works but so does a saucepan ) and add the belladonna, mandrake, henbane and the crossroads dirt. Stir it well before adding the poppet. If there isn't enough water to cover the poppet add more. Leave the poppet in the mix for as long as you want your target to suffer. When the workings done discard of the poppet in running water and pour the mixture away at a crossroads.
