Dead Man's Blood
Dead Man's Blood
A poison to vampires that incapacitates them for a short period of time. When the blood from a dead human is injected into a vampire it induces a blood sickness, causing them to become very weak.
The method of incapacitating a vampire with blood from a dead person is part of vampiric folklore. Tricking a vampire into drinking blood from a dead person to kill him has also been used quite a few times in vampiric tales, notably Interview with the Vampire, wherein the vampire must stop drinking the blood of her/his victim before she/he dies, as drinking blood after death is harmful to the vampire. In Supernatural, Dead Man's Blood has been used as follows:
- Dead Man's Blood is used by John in 1.20 Dead Man's Blood to restrain Kate, when he uses her as bait to lure out Luthor and get the Colt. Its also used to take down Hank with blood-soaked crossbow arrows and later two other vampires.
- Samuel gives Dean a syringe of it when he goes to infiltrate the vampire nest in 6.05 Live Free or Twihard. He fails to use it against Boris as a single drop of blood drips from the syringe and he senses it, but during his slaying of all the nest's vampires, Dean injects another vampire with it and presumably later kills him.
- The Alpha Vampire is given an intravenous drip of dead man's blood to restrain him in 6.07 Family Matters, and dead man's blood is spread on the doors of the building in which he is kept as a deterrent to other vampires.
- When Sam and Dean decide to go after the Alpha Vampire for his blood, they initaly decide to go looking for Dead Man's Blood before coming on the idea of using "vamptonite" from people infected with the Leviathan food-additive.
