whether common table salt, sea salt, or kosher salt -- has a long history of use in rituals of purification, magical protection, and blessing. Among spell-casters working in the European folk-magic tradition, it is a commonplace to lay down a pinch of salt in each corner of a room before performing a spell. This has carried over into contemporary African-American hoodoo practice as well.
Generally speaking, when the intention of a hoodoo spell is primarily protective, salt may be used alone or combined with ingredients like saltpeter and black pepper. For more aggressive spells against enemies, such as Hot Foot and Crossing, salt may be added to red pepper, sulphur, and bluestone.
In Latin America, salt is used to prepare a very important magical formula called Rattlesnake Salt which is believed to lengthen life and to provide protection for the home or place of business.
Additionally, because ritual cleaning is an important facet of African folk-magic, salt is a common ingredient in African-Americanhoodoo spells in which magical protection from evil and breaking enemy work (especially "live things" or tricks under the skin) is accomplished through the employment of ritual baths and floor washes.
