Known Unicorn Blood

Unicorn blood was a thick, silvery magical substance that ran within a unicorn's veins.
==Description==
The blood of a unicorn could be drunk in order to keep a person alive. However, the act of slaying a unicorn would cause the drinker to suffer a cursed life, though the specifics of what this actually entailed were not well known. It was probably non-tradeable, since the sale of this substance was controlled by the British Ministry of Magic, making it strictly forbidden. Firenze and Harry Potter both believed that only those who had nothing to lose and everything to gain would dare drink unicorn blood.
==History==
 
In 1992, Lord Voldemort used unicorn blood to sustain his life, until he could steal the Philosopher's Stone in order to regain his true body. As he was possessing Quirinus Quirrell and inhabiting his body at the time, Quirrell drank the blood on Voldemort's behalf. This was because Quirrell's body was dying as it is from sharing it with Voldemort's fragmented soul.Late in the 1991–1992 school year, when Harry Potter, Hermione Granger, Ron Weasley, and Draco Malfoy were caught out of bounds, they were punished with detention in the Forbidden Forest. At the edge of the forest, they joined Rubeus Hagrid, the Hogwarts gamekeeper, who told them that a unicorn had been injured and that they were to search for it. Prior to splitting up the group, Hagrid pointed out the unicorn blood on the ground.
