Demon Blood in Bottle

Demon Blood in a bottle

"Demon blood" refers to the blood belonging to the human host a demon is currently occupying. Consumption of this substance enhances the drinker's physical and mental capabilities. Consumption on a regular basis can lead to addiction. According to Castiel, a vessel must drink this substance to successfully contain Lucifer, as it greatly strengthens the vessel. Demon blood seems to be somewhat acidic, because when Sam spit the demon blood into one of the hunter's face, it burnt his skin. It will first appear in MCF and the Supernatural and will be a key item in the MCF movies.


2.22 All Hell Breaks Loose: Part TwoEdit

Azazel reveals that he fed Sam his blood on the night of his six month birthday, and also reveals that he did so to all the other Special Children. Demon blood either gives or enhances psychic powers.

These powers vary from premonitions to superhuman strength, telekinesis and the touch of death. These power may begin as weak or minor, but if the individual starts to practice, they can improve their powers (eg. Ava & Max Miller.) According to Jake Talley, after submitting to the pull of their powers, the Special Children can perform "all sorts of new Jedi mind tricks". For more on this see: Special Children on the Supernatural Wiki.

After Azazel dies, Sam's psychic powers seemingly disappear.

He says the blood "strengthens the vessels, keeps it from exploding," and notes that Nick, Lucifer's current vessel, is drinking "gallons" of the stuff. It is speculated that this may have been Ruby's intent all along in getting Sam addicted to demon blood - strengthening him to become Lucifer's vessel.
