Powerful black magic is created with cloth with which a vagina has been wiped after a sexual relation and which has traces of sperm. The mage can perform this sexual union only with a woman he is not married to or in a relationship with. After that this piece of cloth can be used in various ways: for creating love spells, strengthening potency, separation from lovers, etc. The cloth is especially suitable for summoning Jinn-servants. According to the opinion of Iranian and Arabic wizards this piece of cloth contains great power, which comes from the connection of sperm and vaginal secretion, since both fluids contain important magical content. Similarly this cloth can be used as incense for summoning evil Jinn's.
In Bosnian magic a woman which wishes to tie down her husband's sexual power, she uses a cloth to wipe sperm from her body and then goes to the graveyard with the cloth. There she seeks for a grave in which a dead man is buried with the same name as her husband and ties the cloth around the gravestone into a knot uttering: "As this cadaver is helpless and cold so should you be helpless and cold for all other women besides me, with my desire and god's command, amin veledalin!" Then she goes home without looking back.
