Salt is a very valuable substance in many cultures and rituals. For example, salt represented trust and friendship in most cultures in which salt was involved. It is also used in many religious rituals such as when a priest performs an exorcism on a person believed to be possessed by demons, or whenever the Roman Church rite made holy water that could then be used in the exorcisms. However, with all its good points in culture, there is also its negative points in superstition.
