That is an old Mediterranean spell, updated to modern times to include an electrical freezer. You can fine variations and traces of this spell wherever Lemons were grown in Classical times, from the island of Sicily through North Africa, Spain, Greece, and even Israel. It is very common in both Jamaican obeah and African American hoodoo -- and Sicilians in America still work this way as well.
Common variations include:
* using 9 nails or 9 needles to stick the Lemon back together,
* sprinkling the name-paper with Alum Powder (to shut them up),
* sprinkling the Lemon with Red Pepper (to send them away),
* in the pre-freezer days, letting the lemon naturally dry and shrivel.
One beautiful variation is only found where Lemon trees grow -- you cut half the Lemon off the tree and leave the other half attached, then prepare the paper and stick the two halves of the Lemon back together so that the cut half is now reattched to the tree. You wait three days, come back, and pick the Lemon, take out the nails or needles, squeeze BOTH halves of the Lemon into a glass, and prepare food or drink for the hated person with this "poison" Lemon juice.
