At the core of hoodoo are African folkloric practices such as crossing and uncrossing, using spiritual baths and washes, laying tricks, creating grisgris bags, crossroads magic, and foot track magic. Knowledge of these terms is essential in the practice of New Orleans Voodoo.
Simply put, crossing refers to spiritual works that cause harm or bad luck, while uncrossing refers to works that reverse it. There are a number of products sold that are used to aid in putting and end to crossed conditions, particularly when used in conjunction with one or more of the psalms.
For example, products such as uncrossing crystals, oils, sachet powders, and incenses are believed to be particularly effective when used in conjunction with the 37th psalm.
The word cross is virtually synonymous with the words hex, jinx, and curse.
