** ''ComicBook/TheIncredibleHulk'': In an issue from the early 1990s, Jim Wilson, a former teen sidekick of the Hulk, asks him for a transfusion because he's dying of AIDS and thinks that the Hulk's irradiated blood makes him immune to HIV and will cure him. Hulk refuses, worrying that a blood transfusion might also [[SuperhumanTransfusion turn Jim into a gamma mutate]], much like it made Bruce Banner's cousin Jennifer into the ComicBook/SheHulk.

* In traditional Chinese medicine, animal parts and fluids are believed to cure various ailments. However, there's very little scientific evidence to suggest any of it actually works better than a placebo, and unfortunately, it also puts a high bounty on several endangered species.

* In ''Manga/BlueRamun'', the [[ThePowerOfBlood blood]] of members of the Blue Ramun tribe can cure nearly all diseases, neutralize most poisons, and accelerate the healing of wounds. The healing powers inherent in the Blue People are explicitly stated to be one of the most potent magical forces in the entirety of the [[LowFantasy low-magic setting]] -- which is why the Garicalege traffics in [[HumanResources stolen blood]] of the Blue Ramun tribe, and why [[spoiler: Dr. Zai murdered his fellow Blue tribe members and attempted to craft medicine from their hearts]].
* In ''Manga/MissKobayashisDragonMaid'', Tohru claims that dragon saliva has healing properties ([[MundaneUtility on top of being able to wash delicate clothing]]), but Ilulu says that she's just looking for an excuse to lick Kobayashi.

* Invoked by the vampire-like Chui in ''Manga/SazanEyes'', who seems to firmly believe that drinking the blood of Pai, the last Sanzhiyan (Triclop) will make him immortal. It's implied by Parvati though that this is a mere rumor and not an actual fact.
* In a filler arc of ''Manga/OnePiece'', the main antagonist is after a rare and old Millenium Dragon, whose bones are said to grant immortality to all those who consume them. Later on in the arc, his [[TheDragon right hand man]] betrays him to go after the bones himself.
* In ''Manga/SamuraiDeeperKyo'', Demon Eyes Kyou at one point uses his own blood to [[spoiler: bring a dying Kyoshiro back to life]] just out of spite. May also count as a case of NewPowersAsThePlotDemands.

** ''ComicBook/TheIncredibleHulk'': In an issue from the early 1990s, Jim Wilson, a former teen sidekick of the Hulk, asks him for a transfusion because he's dying of AIDS and thinks that the Hulk's blood will cure him, much like it made Bruce Banner's cousin Jennifer into the Comicbook/SheHulk. He refuses.
** Banner seems to think his irradiated blood makes him immune to HIV.

* ''Fanfic/AThingOfVikings'' takes the WesternAnimation/HowToTrainYourDragon example and runs with it; many of the dragons produce substances (mostly venoms, but some tears and salivas) of medicinal value, including anesthetics, heart medications, paralytics, sterilizing agents, and even [[FantasyContraception abortifacients]].

* In ''Fanfic/SongsOfTheSpheres'', not only are the standard healing body parts available to TheMultiverse -- your unicorn horns, your dragon livers, your [[VideoGame/FinalFantasy phoenix down]] -- but eventually [[spoiler: Corona Shimmer]] comes up with a solution involving her own blood. [[spoiler: It bestows ''immortality.'']]

* ''Literature/ArtemisFowl'': Dwarf saliva is apparently a healing balm, at least against burns.
* ''Franchise/{{Dune}}'': The Spice, which is a product of the life cycle of the sandworms of Arrakis and is the most valuable substance in the Known Universe because it can greatly [[LongevityTreatment extend human lifespan]], provide enhanced [[HigherUnderstandingThroughDrugs mental]] and [[SuperSerum physical]] abilities and even enable the power to [[{{Seers}} see through time and space]]. Its value is even greater because of prohibitions on artificial intelligence in this setting, which requires that human potential be maximized.

** Unicorn blood is able to heal people even halfway from death, but due to the atrocity of shedding the blood of something so innocent [[FateWorseThanDeath anyone who drinks from it is cursed with a half-life from then on]].

* In the ''Literature/PitDragonChronicles'' dragon saliva is healing for human wounds and human saliva is healing for dragons wounds. In a subversion, dragon blood is acidic and burns human flesh.

* In ''Literature/StrangerStation'' by Creator/DamonKnight, an alien gives a liquid from its body that cures disease on Earth. Turns out that a human is necessary adjacent to the process, because humans are repulsive to the aliens, and the elixir is actually sweat produced out of their agony enduring our presence.
* ''Literature/TalesOfTheFiveHundredKingdoms'': Unicorns produce a range of healing items. Hair from a dead unicorn prevents illness, hair from a live unicorn not only protects from illness but from evil magic as well. Unicorn horn neutralizes poison, unicorn tears heal mental disorders, and unicorn blood cures diseases and injuries.

* ''Series/AgentsOfSHIELD'': "[[Recap/AgentsOfSHIELDS1E14TAHITI T.A.H.I.T.I.]]" reveals that agent Coulson was resurrected by a drug called GH.325, derived from the bodily fluids of a Kree corpse, code named G.H. It is then used to heal Skye's fatal bullet wounds.
* ''Series/BattlestarGalactica2003'': Hera's hybrid blood [[spoiler: temporarily]] cures Roslin's cancer.
* ''Series/Earth2'': The Grendlers, squat, roughly humanoid primitive scavengers and traders on Planet G889, possess saliva with healing properties so powerful it can cure humans of basically anything.

** "[[Recap/FarscapeS03E05DifferentDestinations ...Different Destinations]]": Fellip urine has healing properties (or at least, can numb pain). Naturally, this being ''Series/{{Farscape}}'', it's played for laughs.
** The Virtual Zhaan's "milk" in the episode [[Recap/FarscapeS04E07JohnQuixote "John Quixote".]] However, this is all part of a virtual reality game and may not be based in the reality of the show's setting.

However, when the Prince's jealous sisters find her and give her a beating, she falls ill and the rosemary wilts. The gardner responsible flees the palace and, in the forest, overhears the discussion a couple of Dragons are having about the rosemary maiden, and one of them confess that the only remedy to save her is a mixture made from the blood from his throat and grease from the other dragon's hide. As soon as the two fall asleep, the gardner kills them, recovers the blood and grease and use it to heal the rosemary plant and save the girl.

* ''VideoGame/Bloodborne'': Old Blood, found within the Pthumerian Catacombs, can heal any injury or disease and lead to the city of Yharnam become famed for healing and medicine. The player character is a pilgrim visiting the city to be cured of an unknown illness. Not only that, the blood echoes stay inside the drinker so that their blood also provides healing. When the game begins, blood drinking is so common that Yharnam residents drink blood instead of wine. Sadly, blood echoes can also turn people into beasts on the Night of the Hunt, an astronomic event, requiring the Hunters to purge them.

* In ''VideoGame/{{Subnautica}}'', the mysterious enzyme needed to cure [[spoiler: the Kharaa plague]] comes from the gastric fluids of [[spoiler: the Sea Emperor Leviathan]].

* ''Webcomic/CrossTimeCafe'': Unicorn boogers have undisclosed magical properties. Oompa Loompas wind up chasing White Pony around, trying to gather said nasal secretions.
* ''Webcomic/{{Starslip}}'' parodies this. Cirbozoids, due to their BizarreAlienBiology, produce a mind-bogglingly wide variety of secretions with an equally wide variety of uses. For any medical condition in other species (or for that matter, any ''non-medical'' emergency), the Cirbozoids secrete ''something'' that serves as an at least temporary solution.

* ''WesternAnimation/AdventureTime'': In "[[Recap/AdventureTimeS6E2EscapeFromTheCitadel Escape from the Citadel]]", the blood from the Guardians of the Citadel can not only heal wounds, but also regrow flesh and muscles--not missing limbs, though.

[[folder:Web Comics]]

A creature, or an entire species, possesses remarkable healing abilities due to a particular bodily product. Usually the product is a fluid, likely saliva or [[ThePowerOfBlood blood]]; in various media, for example, vampire saliva is a natural coagulant and helps the puncture wounds close (incidentally making it a handy tool for maintaining TheMasquerade). However, it could be any other body product, such as urine or bone. The medicinal properties of the product can also range from healing wounds to curing illnesses to bestowing invincibility. Very often, the healing factor only works on other species, not their own, though this is not a strict requirement for the trope.

* ''Literature/{{Semiosis}}'': The sapient {{Plant Alien}}s on Pax can synthesize all kinds of chemicals, from complex drugs to deadly poisons. As one of the smartest, Stevland [[InvokedTrope learns]] to produce fruit with various human medications.

* In the AudioPlay/BigFinishDoctorWho audio play ''The Bride of Peladon'', the Doctor uses his own blood as an antidote, because he'd been attacked and injured badly enough to activate his souped-up Time Lord immune system, releasing special platelets to heal his injuries instead of having to regenerate.

* In the AudioPlay/BigFinishDoctorWho audio play ''The Bride of Peladon'', the Doctor uses his own blood as antivenin, because he'd survived exposure to the same venom before.[[note]]Aside from the time delay, this is how antivenins are actually made, only they generally use large mammals like horses, not a humanoid alien.[[/note]]

* ''WebOriginal/MysteryFleshPitNationalPark'': The [[GeniusLoci Flesh]] [[EldritchAbomination Pit]'s "[[BizarreAlienBiology ballast bulbs]]" secrete a fluid known as amniotic ballast which can treat both cancer and dementia but has been known to cause addictions, with many suffering from "depressive withdrawal periods" after the park was shut down in 2007.
