oils serve multiple purposes within Wicca and WitchCraft. The most common use for ritual oils is to rub them on ritual candles to enhance the potency of spells and rituals. Ritual oils can also be used for other purposes such being rubbed onto various ritual objects, mojo bags, spell kits, and other ritual tools.  Ritual oils can also be placed in oil warmers, and once the oils are heated, they release a steady pleasant aroma for as long a they are heated.
