apotropaic

1. (religion, mysticism) Intended to ward off evil.Examples: "Wormwood [...] was associated with the rites of St. John's Eve, when a crown of the plant was made from its sprays for apotropaic purposes, to ward of malefic spirits."; "A boring subtext, about the wisdom or otherwise of actually uttering Voldemort's name, meanwhile robs the apotropaic device of its force."; "In earlier generations scholars reacted by removing many of these objects from public view, putting them in the ‘Secret Cabinet’ of the museum at Naples or otherwise under wraps. […] More recently the fashion has been to deflect attention from their sexuality by referring to them as ‘magical’, ‘apotropaic’ or ‘averters of the evil eye’."
