Joshua Trachtenberg u svojoj knjizi " Jewish Magic and Superstition: A Study in Folk Religion " navodi narodni recept za lijek protiv malarije (neću ga prevoditi): Take 7 pickles from 7 palmtrees, 7 chips from 7 beams, 7 nails from 7 bridges, 7 ashes from 7 ovens, 7 scoops of earth from 7 door sockets, 7 pieces of pitch from 7 ships, 7 handfuls of cumin, and 7 hairs from the beard of an old dog, and tie them to the neck-hole of the shirt with a white twisted cord.
