The power of imagination and self-suggestion have been documented in most cultures for thousand of years, with the use of witchcraft and sorcery. Both claim to use supernatural or magical powers, such magic spells, curses or magic potions, to influence people either favorably or adversely. Such potions and spells work almost certainly as placebo and nocebo effects, and were based fundamentally on deceptions on gullible people.
