|text=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 ''[http://www.imdb.com/title/tt0110148/ 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 Mandead man's Blood blood has been used as follows:

* Dead Man's Blood is used by [[JohnWinchester]] uses it in [[1.20 Dead Man's Blood]] to restrain [[Kate (vampire)|Kate]], when he uses her as bait to lure out [[LuthorLuther]] and get the [[the Colt]]. Its It's also used to take down Hank with blood-soaked crossbow arrows and later two other vampireswho are all killed later.

* [[Gordon]] uses it in [[2.03 Bloodlust]] to capture and torture [[Lenore]].

* [[Dean ]] injects [[Lucy]] with dead man's blood to capture her in [[3.07 Fresh Blood]].

* [[Samuel Campbell|Samuel]] gives [[Dean ]] a syringe of it when he goes to infiltrate the [[vampire ]] nest in [[6.05 Live Free or Twihard]]. Samuel describes it as enough dead man's blood to drop a linebacker "and then some." 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. Despite the dead man's blood, the Alpha Vampire eventually escapes, though he is weakened and is brought down when the demon possessing [[Christian Campbell]] injects him with two syringes at the same time.

* When [[Sam ]] and [[Dean ]] decide to go after the [[Alpha Vampire ]] for his bloodin [[7.22 There Will Be Blood]], they initaly initially decide to go looking for Dead Mandead man's Blood blood before coming hitting on the idea of using "[[vamptonite]]" from people infected with the [[Leviathans|Leviathan]] food-additive.

* When [[Dean ]] and [[Benny Lafitte|Benny]] go after rogue [[vampire ]] [[Desmond]] in [[8.09 Citizen Fang]], Dean grabs a syringe of Dead Mandead man's Blood blood from the [[Impala]]'s trunk which is shown to be stocked with them. In the fight that follows, Desmond overpowers Dean and smashes the syringe, but it distracts him long enough for Benny to kill him.

* In [[8.18 Freaks and Geeks]], while hunting [[vampire|vampires]], [[Krissy Chambers]] uses darts filled with dead man's blood to take down [[Jimmy Day]] who supposedly killed [[Josephine Barnes]]' family, allowing Josephine to kill him. Later, she shoots [[Seth]], the vampire working with [[Victor Rogers]], in the right eye and chest with the darts, taking him down. This saves [[Aiden]] whom Seth is holding hostage, and allows the group to get his blood to create the cure for his last victim. The vampire is then presumably killed. * [[Dean]] uses a syringe of dead man's blood on an unnamed [[vampire]] son of [[Celia]] in [[9.19 Alex Annie Alexis Ann]] and later kills him. A short time later a newly-turned [[Annie Jones]] injects Celia with dead man's blood to save [[Jody Mills]]. Jody then proceeds to behead Celia. * When [[Lady Antonia Bevell]] is telling [[Sam]] how the British [[Men of Letters]] protect the country from [[monsters]] in [[12.01 Keep Calm and Carry On]], a [[vampire]] entering the UK is shown being injected with dead man's blood and transported for disposal. * As Dean and [[Mr. Ketch]] are preparing to wipe out a vampire nest in Wichita, Kansas, in [[12.14 The Raid]], Dean grabs a syringe of dead man's blood along with a machete from the Impala trunk. * Dean injects [[Officer Doug Stover]] with dead man's blood in [[13.11 Breakdown]] in order to subdue him until they can [[Vampire Cure|cure the man]]. After being cured, Doug regains consciousness with no ill effects from the dead man's blood. * An [[Apocalypse World]] refugee / hunter gives Mary bullets coated in dead man's blood in [[14.01 Stranger in a Strange Land]]. * In [[14.03 The Scar]], a vampire reveals that after being [[Michael's Monsters|enhanced]] by [[Michael (Apocalypse World)|Michael]], they are now unaffected by dead man's blood. In addition, [[Jody Mills]] earlier states that she had [[Alex Jones]] test samples from the corpses of what turned out to be vampires with dead man's blood and it had no effect on them. * In [[15.04 Atomic Monsters]], when ambushing a vampire suspect, Sam hides a syringe of dead man's blood behind his back. However, they realize the girl is innocent as she has braces which vampires don't have. [[Category:Library]][[Category:Creatures & SpiritsPad of Definitions]][[Category:Pad of DefinitionsVampires]][[Category: Weapons & Mystical Artifacts]]
