* In ''Creature Court'', damage from physical trauma (claws, blades etc.) can be healed by drinking the blood of another Court member, with a more powerful donor granting better healing. Damage from [[KryptoniteFactor skysilver]] can only be healed by drinking blood from a [[BadassNormal sentinel]], with the side effect of removing the drinker's powers and making them [[BroughtDownToNormal essentially human]] until it wears off.

* ''ComicBook/XMen'': After the concept of "[[NextTierPowerUp Secondary Mutation]]" was introduced in ''ComicBook/NewXMen'', said mutation granted the character Angel a HealingFactor that was in many ways even stronger than ComicBook/{{Wolverine}}'s. One of the many, many useful properties of said HealingFactor is that Angel's blood alone is powerful enough to cure poisons and diseases, heal near-fatal injuries, and much more.

* ''Fanfic/InfinityTrainBoilingPoint'': Any witch that has a sufficiently strong connection with [[HealingHands Healing magic]] has their blood gain healing properties. [[spoiler: Skara's]] blood is strongly connected that it can actually ''revive'' small critters.

* ''Fanfic/VowOfTheKing'': Unohana's bankai summons a pool of blood (taken fro mall the people she's ever killed) and grants her a potent HealingFactor that can regrow an entire limb in seconds.

--> “My patron is the goddess of blood and bone,” Randal said, “so growing [[spoiler:a new arm]] for me isn’t that hard for her.”

* ''VideoGame/{{Fallout}}'' series: Blood packs first appeared ''VideoGame/Fallout3'', but they only heal a measly 1 point unless the player gets the Hematophage perk, which increases the healing to a decent 20 points. They return in ''VideoGame/FalloutNewVegas'', but there aren't perks that improve their healing, making them poor healing items. Thankfully, Blood packs become more effective in ''VideoGame/Fallout4'' and ''VideoGame/Fallout76'', now that they heal the player by 50 points per second at the cost of drawbacks (for the former, the player gets a 7% chance of getting infected with diseases in Survival Mode; for the latter, the player gets 10 points of radiation).

* ''WesternAnimation/XMenTheAnimatedSeries'': The episode "Have Yourself A Morlock Christmas" sees the outcast Morlocks attracting the attention of the X-Men by raiding hospitals and ambulances. They're doing so because one of their number, Leech, has contracted a serious ailment and the Morlocks lack the ability to heal him. Upon discovering this, Wolverine reveals that a blood transfusion from him has the POTENTIAL to temporarily bestow his own healing factor on the recipient, but is reluctant to try it on Leech because said healing factor could go out of control and kill him, as it has to others Wolverine has tried this with. Ultimately he's persuaded to give it a shot because all other options have been exhausted and Jubilee can't bear the thought of the little Morlock boy dying on Christmas. The transfusion is a success and Leech makes a full recovery.

* ''ComicBook/{{Morbius}}'': Shown several times. He'll be on death's doorstep due to something like starvation ([[DeathSeeker trying to commit suicide]]) or physical injury (tortured by a [[KnightTemplar monster hunter]]) -- get some blood in him and he's good as new. Franchise/SpiderMan's blood can (temporarily) cure him of his pseudo-vampirism, or bring him back to "base living vampire level" when he's become [[LegoGenetics more]] [[BatPeople bat-like]].

* ''Series/InterviewWithTheVampire2022'': In "[[Recap/InterviewWithTheVampire2022S1E1InThroesOfIncreasingWonder In Throes of Increasing Wonder...]]", after TheirFirstTime, Lestat de Lioncourt instantly heals the two bite marks he left on Louis de Pointe du Lac's neck by applying his own vampire blood on them.
