Hoodoo, also known as conjure, is a kind of folk magic that developed from the syncretism of African and Native American traditions, as well as some European magical practices and grimoires.
It is very similar and often confused with Louisiana Voodoo since both incorporate the same material. The two practices are alike in the use of candles, baths, Christian emblems such as the cross or crucifix, holy water and the working with Saints. Louisiana Voodoo practitioners refer to a gris-gris while Hoodoo practitioners call a mojo. Many Hoodoo practitioners in Louisiana are Roman Catholic and also practice some form Spiritualism or Spiritism. They do not typically invoke the loas (African deities) as in Voodoo, and instead use Catholic Saints, as well as Psalms from the Bible, and seals and talismans from the 6th and 7th book of Moses.
In New Orleans, in religion, as in food or race or music, you can’t separate nothing from nothing. Everything mingles each into the other – Catholic saint worship with gris gris spirits, evangelical tent meetings with spiritual church ceremonies – until nothing is purely itself but becomes part of one fonky gumbo. That is why it is important to understand that in New Orleans the idea of voodoo – or as we call it gris gris – is less a distinct religion than a way of life. (Rebennack & Rummel, 1994, p. 159).
A Ju Ju is a blessed object that is said to keep evil and negativity at bay. Ju Ju also refers to the supernatural power ascribed to such an object. A lucky Ju-Ju object can be used to protect the home, car, office, or anywhere you want to keep evil and negativity away.
