in occult lore(the book)you could fuse spells & get interesting effects from plants.
what spells could you bind into catnip & garlic?
what effects could you get from same? 
Tried to get a copy of Occult Lore at my FLGS , but they were out.
Fortunately another FLGS has a copy for me.
Spells should be obvious :
Catnip : Summon and Bind Felines.
Garlic : Greater Magic Circle of Protection from Vampires.
try online and/or local bookstores for the book in question.
