Dude, it's not real, this person swallowed the items probably because of a mental illness and their susceptibility to believe in black magic which psychologically changes the way they think as they actually believe it's real.

This is the serious answer, please don't waste your time and money on this non sense and move on with your life, there is absolutely no such thing as black magic. It's all in your head, if you think you are cursed and cannot sleep then you cannot sleep, it's not because of the magic, it's because you think it's real and that's what is effecting you. It's called the placebo effect in medicine as people sometimes get cured when they eat fake medicine, this is just the opposite way around.
