No I've never read any of the harry books or seen any of the movies. But unicorn blood or a unicorn's horn, sometimes powdered, are pretty standard ingredients in magical concoctions across many diff3rent franchises. But I still don't see why. I stand by my question: if they so full of magic, how come they never use mwgic to do anything? I swear all unicorns might as well just be horses with a hood ornament.
