Both Hoodoo and Voodoo have very rich African roots, and that is mainly where the similarities end. Voodoo (also called Vodou or Vodoun) is a true religion, with spiritual rituals and a pantheon of Gods and powerful spirits.
On the other hand, Hoodoo is a specific type of magickal practice that is not religious in itself. Sometimes called rootwork, Hoodoo uses a lot of herbs to create amulet, potion or charm-based spells. These spells tend to be very simple, with just a few ingredients to make a charm. Even though, good rootwork can be extremely powerful magick.
Though not really part of Voodoo, I've included a page of Hoodoo spells anyway. It fits here better than anywhere else.
Home Protection Amulet
This is a simple example of some Hoodoo magic you can use to protect your home from negative energies.
Wrap the seeds in a bundle of red flannel, and nail the charm to the back of your front door. This will keep bad energy and negative spells out of your home.
Hoodoo Luck Charm
Another form of charm bag to bring you some good luck. You may have to check out an herbal shop or a Wiccan store to find the ingredients though.
First, light the candle and let it burn down to just a little stub. Then gather up the remaining wax and make a charm bag out of green cloth for the wax, nutmeg, root and coin. Carry it with you for good luck (usually the financial kind or gambling).
If you are hoping to use Hoodoo to find some romance, there is a new page of Hoodoo love spells that would be worth visiting.
