To hang one in the room was supposed to keep away disease (modern science to some extent does agree with this as if one is cut and left open it will attract germs), whilst sleeping with one under your pillow is supposed to help you dream of your lover to be. Onions could also be used in love in love divination if you are torn between two lovers by carving the name of the person on separate onions and placing them in a warm place. The first to sprout first indicates the most powerful love. Disciplining someone with the cane could fail on two counts if an onion was used according to folklore. Rubbing the onion on the appropriate part of the anatomy would prevent the cane being felt, whilst rubbing the onion on the cane would ensure that the cane would spilt on the first blow.
