Unicorn blood 1

Unicorn blood

" is a monstrous thing, to slay a unicorn. Only one who has nothing to lose, and everything to gain, would commit such a crime. The blood of a unicorn will keep you alive, even if you are an inch from death, but at a terrible price. You have slain something pure and defenceless to save yourself, and you will have but a half-life, a cursed life, from the moment the blood touches your lips."
Firenze explains to Harry Potter why the slaying of a unicorn is a crime.

Unicorn blood is a thick, silvery substance that runs within a Unicorn's veins. The blood of a unicorn can be drank in order to keep a person alive. However, the act of slaying an unicorn will cause the drinker to suffer a cursed life.


Lord Voldemort had used unicorn blood while attempting to regain his former power. He did this while in the body of Quirinus Quirrell.
