The White Magic Lexicon is a tome of white magic known to contain reversal spells for dark magic.
History[]
After Lora is apparently cursed with an Aging Spell by a witch, Castiel contacts Rowena for a solution when he could not heal Lora. Rowena points him to the White Magic Lexicon to find a reversal spell. Jules is able to find the book and though they perform the reversal spell, it fails to work as Lora is not under an aging spell.
