The word Voodoo itself means spirits and Voodoo is a religious or magico-religious practice which aims at connecting spirits and mortals. This is only possible through a magical process using a gris-gris. A gris-gris' definition is nuanced-- it can either be the magical act or the object used for magic, or even both... Voodoo can be used to help you focus on desires you'd like to bring... love, luck, money etc. Of course, you can also err on the other side too! However, concentrating on the good (as a white witch does) these are the things the different colours can help you with. Yellow - success Green - money White - healing Red - power Purple - spirituality Blue - love Black - protection against negativity. This shower steamer will last a couple of showers, you simply pop in the corner of the shower floor or on the ledge, (not under you), and the water will activate it so that it will fizz while the essential oils are released and you have aromatherapy in the shower, leaving you feel positive and fresh. These are made with all natural ingredients to order.
