->''"The sun's fire makes a garden grow,\\
A forge fire tempers steel.\\
Why then are you surprised to find\\
A fire that can heal?"''
-->-- '''The Arbolit''', verse 3, from ''TabletopGame/MagiNation''

Fire burns, and has been [[KillItWithFire used as a weapon]] since before recorded history, but sometimes that gets turned around and fire is instead used to heal or treat wounds.

In works that tend towards realism, this most often takes the form of cauterization: the medical practice of searing a wound to prevent blood loss and reduce the likelihood of infection.[[note]]It's worth noting that, in modern medicine, this has been largely discredited, at least given the available alternatives; these alternatives may not have been available before the 20th century.[[/note]] In more fantastical works, fire may heal by means of the concept of [[FirePurifies "purity"]], burning away contamination and leaving the essence of a thing behind.

A common element with both mundane and fantastic uses of fire to heal is that it causes a great deal of pain in the process, thus lending itself to metaphors about enduring temporary hardship for long-term gain. For similar reasons, it can be an expression of BadPowersGoodPeople, with a power that's typically used for harm turned around to heal instead. In other cases, a being who is cursed to be unable to use their power for good may use this form of healing as a kind of LoopholeAbuse.

Some attacks, like a LaserBlade or [[EnergyWeapon Frickin' Laser Beams]], may cauterize wounds in the process of being employed, but that's not typically a case of this trope so much as it is a justification for BloodlessCarnage. Real life laser wounds would actually be a lot nastier than fiction anyway, since they would not cauterize in any helpful way, and there would be gruesome damage from water inside the flesh explosively vaporizing.

Compare FeedItWithFire, where fire or lightning ''in and of itself'' has a curative effect.

Related to TheFlameOfLife, where fire symbolizes life.

Contrast KillItWithFire. See also FirePurifies and WorstAid. See also HealItWithWater and HealingWinds.

Can be an ability of SacredFlames.

As noted above, the practice of cauterization to close wounds has been largely discredited in modern medicine, so '''DontTryThisAtHome'''.

[[folder:Anime & Manga]]
* In ''Manga/AliceInBorderland'', Akane gets impaled through the abdomen and, lacking any other means of first aid, has to cauterise the wound using a hot pipe.
* ''Manga/BakiTheGrappler'' has Baki sterilizing the bite Ando got from the Yasha Ape by spreading gunpowder on it and setting it off.
* Fana from ''Manga/BlackClover'' has the Flame Magic recovery spell Phoenix Robe (that she got from the body of the human Fana), that produces flames able to heal herself and others.
* ''Manga/BlueExorcist'' the Impure King arc shows [[spoiler: Rin using his [[HellFire blue flames]] in this way. His way is more interesting and most likely valid; he ''burns'' away the disease and every piece of the Impure King specifically targeting it while leaving all the exorcists, plants and whatnot unharmed. He had to use a purification mantra and needed help from a high ranked demon as well, but the targeting was all him.]]
* Natsu of ''Manga/FairyTail'' does this to one of his guildmates (only in the manga).
* At the climax of the final arc in ''Manga/FlameOfRecca'', Recca uses the ability of the final flame dragon, Resshin, whose power is [[spoiler: to turn the soul of any human he chooses into his own flames, reviving Yanagi, whose soul was about to be devoured by the Tendou Jigoku, as part of his flame. As Yanagi’s ability in life was that of healing, Recca’s flame gains the power to heal, which he uses not only to cure the injuries of all his friends, but also cures the tortured souls of the people used to create the Tendou Jigoku, effectively destroying its source of regeneration and making it vulnerable enough to be destroyed.]]
* In ''Manga/FullmetalAlchemist'', Roy Mustang sears his own wound closed after getting stabbed by [[WolverineClaws Lust]]. It's only a temporary measure, though, and he winds up collapsing shortly afterwards and has to go to the hospital, and he even admits that in doing so, he almost passed out from the pain.
* In the fifth ''Literature/TheGardenOfSinners'' movie Paradox Spiral, Enjou Tomoe presses the stub left over after his arm fell off against a very hot slab of metal to seal it up. Even if [[spoiler:the act itself is somewhat worthless since he's a fake human, and the stub wasn't even bleeding...]] it's the thought that counts.
** Possibly trying to [[spoiler: burn shut his shoulder to stop the gears inside falling out.]]
* [[PlayingWithFire "Flame Hero", Endeavor]] from ''Manga/MyHeroAcademia'' has used his powers to cauterize life threatening injuries occasionally to keep people alive long enough for proper medical personell to arrive.
* ''Manga/OnePiece'', Marco the phoenix has a devil fruit that lets him transform into a phoenix made out of blue fire that heals injuries.
** "Foxfire" Kin'emon uses his flaming sword technique to cauterize a severed arm at one point.
* In ''Manga/PokemonAdventures'', Entei's flames apparently have some kind of healing power as it cured Blaine of [[ItMakesSenseInContext his Mewtwo cancer]].
* ''Anime/{{Promare}}'': The Burnish can regenerate which protects them from dangers such as being encased ice, burned or shot, but they will die and turn to ash if their flames go out. To prevent this, Burnish can perform a sort of CPR by blowing their flames into a dying person, akin to mouth-to-mouth. A successful attempt can allow a Burnish to regenerate their entire body even if they are already turning to ash, though the procedure is not guaranteed to work, [[spoiler:as seen when Lio fails to save Thyma]].
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/ElksRun'': When Adam Smith is shot in the stomach, and his friends carry him into a mine for shelter, one of them cleans the wound of infection using ''explosive natural gas'', carefully contained by a miner's helmet.
* ''ComicBook/GIJoeARealAmericanHeroMarvel'': Serpentor is grazed in the arm during a firefight with the Joes, but uses a hot knife to cauterize the wound. As he's binding the wound, he gives a pep talk to the Cobra troops watching him, boasting that they are too tough to let such trifling things stop them.
* In the third volume of ''ComicBook/NewMutants'', Doctor Nemesis triggers Magma's molten form in order to cauterize some wounds she'd suffered earlier.
* ''ComicBook/{{Superman}}'':
** In one ''ComicBook/SupermanBatman'' issue, a SerialKiller cuts off a thief's hand and Superman uses his heat vision to cauterize the wound.
** In ''ComicBook/Supergirl2005'' story arc ''ComicBook/GirlPower'', ComicBook/{{Supergirl}} uses her heat vision to cauterize a gunshot wound on Starfire's right shoulder.

* During ''ComicBook/XMen: Messiah Complex'', Bishop used Sunfire's flaming body to cauterize his severed arm.
* ''ComicBook/AgeOfBronze'': This trope is how Telephus' wound is finally healed. The spear that injured him has the metal blade heated in a fire and the infection in the wound burned out.
[[/folder]]

[[folder:Fan Works]]
* ''Fanfic/AbraxasHrodvitnon'': In this ''Franchise/{{Godzilla}}'' Franchise/MonsterVerse fanfiction, during the battle on Yonaguni, Rodan's bio-volcanic heat cauterizes [[Characters/AbraxasHrodvitnonMonsterX Monster X]]'s fresh injuries.
* The fanfic ''Fanfic/BookFiveLegends'' we're introduced to a firebender healer by the name of [[MeaningfulName Temuji]].
* In the ''WesternAnimation/AvatarTheLastAirbender'' fanfic ''Fanfic/EmbersVathara'', Zuko rediscovers techniques where [[PlayingWithFire fire bending]] can be used to heal. When he uses it during his travels through the Earth Kingdom, he has to disguise it as massages with hot stones or steaming water treatments.
* In ''Fanfic/FatesCollide'', Mordred impales Edmond Dantes and warns him [[WorstAid not to pull the sword out]] or else he will bleed to death. He gets so angry that he pulls it out anyway and seals the wound shut with a blast of fire. Martha calls him a moron and says he's lucky he didn't die.
* Used in an emergency to stem Tercio's bleeding in ''Fanfic/JustBeforeTheDawn'', until he's able to receive proper medical care for his wounds.
* ''Fanfic/PhoenixsTearReignition'': The Tear gives Hare healing abilities that take the form of magical flames. While this isn't generally presented as painful, described as a [[FireOfComfort soothing heat]], ''Eigengrau'' has him explicitly sealing [[spoiler:Gray Wolf]]'s wounds through cauterization.
* ''Fanfic/TriptychContinuum'':
** Celestia's connection to SUN allows her to channel heat to burn out infection or sickness. It's noted that the only reason this doesn't do more harm than good is that Celestia's control of the channeled heat is precise enough to only burn the infection, while leaving the healthy tissue surrounding it untouched.
** In ''Glimmer'', Spike is suffering from a buildup of fluid in his lungs (dragons are built for hot, ''dry'' climates, and they're in the middle of a rainforest). To help treat this, Twilight starts a fire and has Spike sit in it. Superheating his body in this way doesn't hurt him, but it does literally boil the excess fluid out of his lungs.
* In ''Fanfic/WarAndPeaceInMind'', this becomes a new aspect of Warren's power. However, [[CastFromHitPoints overusage of it can possibly put him out or worse]].
[[/folder]]

[[folder:Film -- Animation]]
* ''WesternAnimation/BatmanGothamKnight''. In "Working Through Pain", Batman uses some kind of glowing disc from his utility belt to seal a gunshot wound.

* ''Film/{{Botched}}'': After Boris has his hand cut off by his own BoobyTrap, he cauterizes the stump with fire.
* In ''Film/{{Braveheart}}'', [[TheBigGuy Hamish's]] [[OldSoldier father]] needs to have a wound cauterized with a red hot iron after receiving an arrow to the shoulder. In a nice nod to how such a thing might have played out in those days, alcohol gets a lot of use both as an [[LiquidCourage anesthetic]] and [[HealItWithBooze disinfectant]]. Unusually for this sort of scene, it's played more for laughs than drama, as a whole line of [[BraveScot brave Scottish warriors]] get handed the iron and told that they're going to be the one to use it, only to immediately pass it on to the next guy, saying "You do it... I'll hold him down". When they finally get some poor sap to actually do it, there are at least half a dozen men holding the patient down. Sure enough, the first thing dad does when he gets up after the treatment is to punch the guy who applied the iron, even though the guy is in the middle of frantically apologizing.
* ''Film/ClashOfTheTitans2010'': The Djinni summons up an eerie blue flame to purify Perseus' poisoned wound. It's extremely painful and he doesn't bother to ''warn'' Perseus in advance, so he has to fight off several of Perseus' companions before they realize he's actually healed him.
* In ''Film/DayOfTheDead1985'', one of the protagonist's arms is cut off after he is [[ZombieInfectee bitten by a zombie]]. His friends then cauterize the stump with a makeshift torch. Whether or not this saved him from infection is unknown, as he was devoured by zombies soon after.
* ''Film/DeadtimeStoriesVolume2'': In "The Gorge", after they amputate Gary's leg with an ice axe, Craig cauterizes the stump with a flare.
* In ''Film/{{Dragonheart}}'', after Draco performs the dragonheart ritual, he gives the wound a quick shot of flame to cauterize it.
* ''Film/TheEqualizer''. Done ''twice'' by Robert [=McCall=]. The first time he warms up some honey on a stove, then pours it on a wound in an AfterActionPatchUp, then during the final battle he heats up a doorknob with a blowtorch and presses it on a gunshot wound.
* In ''Film/EveryLastOneOfThem'', Hunter cauterizes a gunshot wound in his shoulder by heating the tip of his knife in a kerosene lamp until it red hot, and then pressing it into the wound.
* Parodied in ''Film/FeastIII'': When Jean Claude's arm won't stop bleeding Bartender packs the wound with gunpowder and lights it, blowing off Jean Claude's arm.
* ''Film/GodzillaKingOfTheMonsters2019'': [[Characters/MonsterVerseGodzilla Godzilla]]'s retreat where he recharges his energy is revealed to be a highly-radioactive subterranean cave with geothermal activity, hot enough to potentially kill any human who steps foot inside. What's more, [[spoiler:after Godzilla is severely crippled due to the Oxygen Destroyer's effects, the heroes massiely speed up his regeneration from years to a few seconds by [[NuclearOption detonating a nuclear warhead right in front of him]]]].
* In ''Film/{{Hidalgo}}'', after falling into a concealed trap in the sand filled with wooden stakes, the titular character seals the stab wound his horse suffers using his heated knife.
* ''Film/IndianaJonesAndTheTempleOfDoom'': When Indy is BrainwashedAndCrazy from being force-fed the blood of Kali, Short Round snaps him out of this by briefly burning him with a torch.
* In ''Film/JohnCarpentersVampires'', Montoya does this pretty much every time he's wounded, once with a lighter, and once by firing his sub-machine gun into the air then holding the hot barrel to the wound. It is unclear whether this is to prevent vampirism from being transmitted or to attempt to heal the wound itself.
* ''Film/TheKarateKid2010'': Twice in the movie, Mr. Han uses traditional Chinese fire cupping to heal Dre's wounds. The technique is indeed a real (if medically scrutinized) form of physical therapy still practiced today, but [[ArtisticLicenseMedicine the capabilities shown in the movie are heightened beyond its real-world applications]] (for instance, it will definitely not heal a broken leg), though it does allow for the sight of Creator/JackieChan [[RuleOfCool wielding healing fire with his bare hands]].
* ''Film/TheKiller1989'' does this with gunpowder from a shotgun shell. Being as neither of the heroes has anesthesia, the cop gives the title character a big stick to bite down on before igniting the powder.
* B-Western ''Film/TheLastOutlaw'' features the leader of an outlaw group who pours gunpowder into a shoulder wound and lights it on fire to cauterize it. Quite {{squick}}y and cringe inducing because we see the flames spouting out of both sides of his shoulder since the bullet went straight through.
* In ''Film/ManOfSteel'', Lois is injured by a Kryptonian security robot when she discovers the ship. Clark notes that she's hemorrhaging internally and proceeds to cauterize the injury with his heat vision.
* Whatever the hell that blue stuff is that the Franchise/{{Predator}} puts in his wounds to stop the bleeding. In [[Film/{{Predator 2}} the second movie]], it appears to seal off the stump of his severed hand quite efficiently, and it clearly hurts like hell.
* In ''Film/OutOfReach'' William Lansing heals Irena's gunshot wound with a knife heated over a burning stove. [[WeHaveToGetTheBulletOut After digging the bullet out]], of course.
* In ''Film/RamboIII'', Rambo gets impaled through the stomach with a bit of wooden shrapnel; leaving both an entry and exit wound. After pulling the remaining shrapnel out he cuts off a tip of a bullet, pours the gunpowder into the wound and then sets it alight; with flames coming out of both sides. With this being Rambo, the wound barely slows him down, and fortunately for Rambo, setting off a gunpowder explosion inside of an open wound going deep through his body did not cause him to die of gangrene and sepsis less than a week later.
* In ''Film/TheRevenant'', Glass seals his throat wound by covering it with gun powder and then igniting it.
* In ''Film/Revenge2017'', Jen heals her injuries by cutting open and flattening an aluminum beer can, holding it over the fire and then pressing it against her wound. In doing so she inadvertently brands the beer can's logo on her flesh, which happens to be ThePhoenix. (The film has a lot of phoenix symbolism in it.)
* Film/{{Riddick}} is stabbed with a giant alien stinger. He has to leave it in the wound to plug the hole until he can find some [[GreenRocks glowing rocks]] to cauterize the wound.
* ''Film/RobinHoodPrinceOfThieves'' showcases prisoners getting their hands cut off by a searingly-hot scimitar. Next they put Robin on the chopping block and let's just say that the wardens were sent into early retirement.
* [[spoiler:Doctor Gordon]] is shown to have survived his wounds thanks to this technique in ''Film/Saw3D''.
* The Headless Horseman from ''Film/SleepyHollow1999'' decapitated his victims, and it was noted that the head wounds were cauterized instantly, as though the blade used was red hot. Constable Crane wondered how this could be possible, due to the absence of blistering of the skin or scorch marks on the clothing. The superstitious believed it to have been caused by "[[{{Hellfire}} the Devil's fire]]."
** Constable Crane himself survives and recovers from a stab wound much more quickly than he should have due to this effect.
* ''Film/StarTrekBeyond''. Bones uses a captured energy weapon to heat up a shard of metal, using it to cauterize Spock's wound. This is only a holding action, as they have to walk to a place that fortunately has more advanced medical equipment.
* [[LaserBlade Lightsabers]] in the ''Franchise/StarWars'' franchise appear to automatically cauterize flesh as they cut, with one exception: In ''A New Hope'', there's a bit of blood when Obi-wan cuts off Ponda Baba's arm in the cantina (may have been a very, very minor example of EarlyInstallmentWeirdness).
** The [[Franchise/StarWarsExpandedUniverse Expanded Universe]] attempts to justify it by saying his species' biology is just weird like that.
* The main character of ''Film/Ultraviolet2006'' cauterizes one of her wounds with the heat generated by firing her gun.

[[folder:Literature]]
* Literature/CiaphasCain, '''[[FakeUltimateHero HERO OF THE]] [[DrinkingGame/TVTropes IMPERIUM]]''', has mentioned several times that since lasgun shots cauterize the wound, it's better to be hit with a lasgun than a solid-slug weapon.
* Inverted in ''Literature/CodexAlera'': in this setting, ElementalPowers are capable of many things that they aren't capable of in some magic systems. [[MakingASplash Control over water]] includes the ability to heal people, possibly because most of the human body is water. However, ElementalRockPaperScissors is also in effect, and touching or being near one element prevents the other from being used. Therefore, cauterization makes it nigh impossible for a watercrafter to heal the wound.
* In the first book of the ''Literature/ColdfireTrilogy'', the Hunter uses coldfire (fae generated blue flames that are as cold as real fire is hot) to cleanse Senzei's gangrenous wound.
* Similarly to the above, the dragon Firedrake demonstrates that his firebreath, which is also blue, actually heals people instead of burning them in the book ''Literature/DragonRider'' by Cornelia Funke.
* In Ed Greenwood's ''TabletopGame/ForgottenRealms'' novel ''Spellfire'', it's eventually discovered that the eponymous fire can in fact be used to heal, not just to burn. Justified here in that what it really is is the barely controlled raw essence of magic itself, not just any old fire spell or mundane form of combustion.
* In ''[[Literature/GreenHills Green Hills and Dragon Tales]]'', John amputates Ellis' rotting leg by burning it off with dragonfire.
* In ''[[Literature/TheHeroesOfOlympus The House of Hades]]'', Percy and Annabeth [[spoiler:drink from the River Phlegethon, a river of literal fire, to heal themselves from the poison of Tartarus.]] It works.
* The dragons and Dragonlords in Joanne Bertin's ''The Last Dragonlord'' and ''Dragon and Phoenix'' can channel their fire breath into a healing ability. ItMakesSenseInContext.
* In ''Literature/{{Misery}}'' by Creator/StephenKing, Anne Wilkes uses a blow torch to prevent blood loss when she amputates the protagonist's foot.
* The ending of ''Literature/MakingMoney'' had Moist cauterizing the [[spoiler:gangrenous finger of Cosmo by bringing his imitation Vetinari ring under the sun, making its stygium components white-hot]].
* ''Literature/PhoenixAndAshes'': After being drugged, Eleanor uses a fire spell intended for purification to purify the morphine out of her blood.
* In ''Literature/ASongOfIceAndFire'', Victorion Greyjoy has to have his hand cauterized by a red priest to save him from blood poisoning. However, this priest worships a god of fire and has received a power boost due to [[TheMagicComesBack dragons reemerging from extinction]], and as a result, Victorion's arm becomes superhumanly strong.
** Boiling wine is a standard treatment to simultaneously cauterize and sterilize wounds.
* How Mackenzie Calhoun of the ''Literature/StarTrekNewFrontier'' series by Creator/PeterDavid got his [[GoodScarsEvilScars facial scar]]: self-cauterization while seriously injured and lying alone in the desert with a laser welder.
* Happens a few times in Creator/BarbaraHambly's ''Literature/SunWolfAndStarhawk'' books, usually after [[OurZombiesAreDifferent nuuwa]] attacks. [[spoiler:And then, there's Sun Wolf [[EyeScream gouging out his own eye]] and cauterizing the socket]] in ''Literature/TheLadiesOfMandrigyn''.
* [[OurDragonsAreDifferent Kantri]] of ''Literature/TalesOfKolmar'' flame their own wounds clean, especially when they've been fighting demons, which leave a kind of taint otherwise.
* In ''Literature/TheTenetsOfFutilism,'' Joe cauterizes the enormous wounds cut into Sasha's arms and stomach with a lighter, saving her from bleeding out.
* Joelle Charbonneau's ''Literature/TheTesting'' has Cia cauterizing Tomas's wound with a hot piece of metal.
* Kaladin from ''[[Literature/TheStormlightArchive The Way Of Kings]]'' by Creator/BrandonSanderson uses such techniques several times, generally when working in sub-par conditions or with suboptimal equipment - which is standard in the bridge crew.
* In ''Literature/TheWheelOfTime'', the Weaves for Healing traditionally only use Air, Water, and Spirit. Until Nynaeve discovers that the most powerful form of Healing includes the two other elements, Fire and Earth, which can accomplish many more powerful feats of Healing, such as reversing the effects of those who have been severed of the [[FunctionalMagic One Power]].
* In ''Literature/WingsOfFire'', Peril uses her burning scales to heal [[spoiler:Clay]] when he is [[spoiler:bitten by a venomous dragon bite viper]]. It ''is'' noted that he would have died from his burns if he wasn't [[spoiler:virtually immune to fire and heat]], and he still [[spoiler:was permanently crippled by the injury.]]

[[folder:Live-Action TV]]
* ''Series/{{The 100}}'' makes frequent use of this since the characters are living in the wild on earth with no real medical supplies. On one instance after the character applying the red hot iron has just acknowledged that the wound has ''already'' been cauterized and is likewise already infected. The only reason none of the patients die from infection is because there is a local species of seaweed that has powerful antibiotic properties, and it is readily available.
* In the pilot of ''Series/AnimalKingdom'' Craig cauterizes his gunshot wound. He still almost dies of infection before a doctor in Mexico cures him.
* ''Series/TheBoys2019''. In "The Bloody Doors Off", Starlight uses her energy superpowers to cauterize Hughie's wound so he won't bleed out before they can get him to a hospital. Though she's delayed in doing so because she needs a working power source to draw energy from.
* ''Series/BurnNotice'' inverted this by having Michael use a liquid nitrogen gun to both cauterize a wound (which he secretly [[IndyPloy had planned]]) and to sabotage the bad guys pistol.
* Subverted in ''Series/Charmed1998''. Colonial era witches were about to cauterize someone's wound, but Piper instructs them to just use hot water and soap.
* ''Series/ChrisRyansStrikeBack''. The protagonist does this in Zimbabwe, also using the powder from a cartridge.
* ''Series/CowboyBebop2021''. A medical device emitting a laser beam is shown being used to treat bullet wounds, such as when Jet Black patches up Faye Valentine in "Callisto Soul". Presumably however it's backed up by other treatments like antibiotics.
* Spoofed in ''Series/{{Danger 5}}''. Jackson gets impaled by a splinter, so [[RatedMForManly he fires his Luger into the wound to sterilize it]].
* In season one of ''Series/Daredevil2015'' Matt Murdock uses a road flare to cauterize a Russian mob leader's bullet wound as per the advice of Claire Temple, a nurse with a talent for on-the-fly medical assistance. He's in an AbandonedWarehouse with no first aid kit, and has to keep the mobster from bleeding out long enough to spill the goods on the mysterious man he's been working with. The mobster had earlier had Claire tortured in an effort to find out Matt's SecretIdentity, so [[AssholeVictim she's not particularly bothered how much it hurts the man]].
* ''Series/{{Forever|2014}}'': In the first episode, a suspect throws poison on Jo's hand. It's already started to penetrate Jo's skin, so Henry neutralizes it by squirting ethanol over the area, then ''setting it on fire'' and not letting her put it out for several seconds.
* In ''Series/Frontier2016'' Declan Harp has been tortured (but don't worry, "TortureIsIneffective") and is examining his wounds. It doesn't look all that bad and in fact seems to be healing nicely, but a hot blade is still called for.
* ''Series/GameOfThrones''.
** Averted in "Mockingbird" when Sandor Clegane is bitten on the neck, yet refuses to allow Arya Stark to cauterize the wound due to his fear of fire. Arya cleans it with water, but it still gets infected, [[WorfHadTheFlu hampering Sandor's fighting skill later on]].
** In "Beyond the Wall", Lord Beric uses his FlamingSword to cauterize the wounds of his friend Thoros of Myr. [[spoiler:However it's only a temporary measure, and without medical care available he dies of his injuries.]]
* ''Series/Halo2022''. In the Season One finale, Riz gets half her chest blown away by a plasma grenade. Master Chief disconnects a fuel line, ignites it with a spark and turns it directly on the wound. Anyone but a SPARTAN SuperSoldier would likely have died of shock.
* In the 2020 miniseries ''Series/TheHead'', the doctor on an isolated Antarctic research station gets shot accidentally and has to advise her boyfriend on how to treat her injuries, including cauterizing a vein. In this case he uses the proper surgical tool for this trope--the problem however being that the doctor can't take anything except a local anaesthetic as she has to be fully conscious.
* In the ''Series/{{Lost}}'' season 1 finale, Sayid cauterizes Charlie's wound by opening a bullet and igniting the gunpowder. This wound is on Charlie's forehead, just above his eye. Yee-ouch!
* There's another example in ''Series/{{MacGyver|1985}}''. In the episode "To be a Man" Macgyver's gunshot wound is cauterized with a red hot poker. He passes out from the pain.
* ''Series/TheMandalorian''. In the second episode the title character shows he's NotSoStoic as he's heard groaning in pain as he cauterizes a wound he received from a Trandoshan's vibro-axe. Unknown to The Mandalorian, The Child he just rescued [[HealingHands could have healed him a lot less painfully]].
* ''Series/SpartacusBloodAndSand'' shows Crixus' nasty chest wounds being cauterized. It hurts so much he has to be strapped to the table.
** In ''Spartacus Vengeance'', Nassir's wounds are treated this way. There is even a CallBack to it saving Crixus. In the final episode Spartacus tries to do it for [[spoiler:Mira]], but it's too late.
* ''Series/{{Westworld}}''. The body techs use a medical cauterizer to seal wounds on the cyborg hosts. When a tech gets a SlashedThroat, his colleague uses one so he won't bleed to death. Turns out it ''really'' hurts when used on a human being.
* ''Series/{{Yellowjackets}}'': The titular soccer team are stranded in the Canadian wilderness after a plane crash. Assistant Coach Scott survives but his leg is crushed under the wing. Misty, the equipment manager, grabs an ax and chops off his mangled leg. Then much later, she cauterizes his wound.

* ''TabletopGame/DungeonsAndDragons''
** Assassin bugs, bipedal insectoids that have been around since 1st Edition, are feared for [[FaceFullOfAlienWingWong injecting their young into living victims]], who are EatenAlive by maggots burrowing towards their heart. Their 5th Edition write-up notes that, should fire be applied to an assassin bug wound in the following round, the victim will take some damage, but the maggots will be killed. Otherwise, the maggots go too deep into the victim for the fire to touch, and will require magic like ''cure disease'' to remove.
** The 5th Edition "Circle of Wildfire" druid subclass plays into this heavily. Half of their always-prepared spells deal fire damage while the other half heal; their 6th-level ability can give them a bonus to either healing or fire damage rolls; and their 10th-level ability lets them create a flame which can either heal or harm.
* ''TabletopGame/MagiNation'' provides the page quote, from the flavor text of one of the cards. Many of the spells and creature abilities from the Cald (the fire domain) deal with healing your creatures or rearranging their energy in general. However, this trope is averted in the Gameboy Color game based on the TCG.
* ''TabletopGame/{{Pathfinder}}'': Sorcerers of the Phoenix Bloodline gain the ability to use fire to heal their allies, although exactly how this functions varies by edition. In 1[[superscript:st]] Edition, they can choose to cast [[PlayingWithFire Fire spells]] so they heal half the amount of HitPoints they would ordinarily damage, while in 2[[superscript:nd]] Edition, they gain special focus spells that use fire to heal, one of which also harms enemies, as well as access to more healing spells than primal casters can normally cast.
* In ''TabletopGame/PrincessTheHopeful'', Princesses of Swords have access to Charms that can literally burn sickness or poison away, while leaving the body unharmed. Similarly, the Princesses of Storms can burn away their traumas rather than having to recover in the regular fashion.
* ''TabletopGame/RottedCapes'' takes place in a ZombieApocalypse, where the only sure way to keep from being infected once bitten is to cauterize the wound ASAP.
* ''TabletopGame/WarhammerFantasyRoleplay'' 4[[superscript:th]] Edition: Pyromancers can [[HealingHands instantly heal wounds]] with the "Cauterize" spell. If the lucky recipient fails a saving throw, they pass out from the pain and heal with permanent scarring.

* In the Creator/AdultSwim.com game ''VideoGame/AmateurSurgeon'', Alan Probe, the titular pizza delivery guy turned brilliant unlicensed physician, uses a disposable lighter (and in the sequel, a match) to cauterize wounds after stapling them shut. Also to attach transplanted organs. He must be a genius, because he somehow makes it WORK.
* In ''VideoGame/TheBindingOfIsaac Rebirth'', you can get an item called Pyromaniac, which allows you to heal half a heart each time you get hit by an explosion, including your own bombs.
* In ''VideoGame/{{Borderlands}}'' the Soldier class has a talent called "Cauterize". It allows him to [[HealingShiv heal allies by shooting them]].
* The Thermal powerset used by Controllers and Corruptors in ''VideoGame/CityOfHeroes'', which has powers like "Warmth" and "Cauterize". Aside from the names, they work like any other healing powers.
* The Fire powerset in ''VideoGame/DCUniverseOnline'' is generally more of the KillItWithFire variety, but it does have a few abilities that heal the user, though ''only'' the user as Fire is one of the [[StoneWall Tank]] roles instead of a Healer.
* One of the many [[{{Squick}} lovely]] healing animations in ''Franchise/FarCry'' involves lighting a bundle of matches and jamming it into the wound.
* ''VideoGame/DarkSoulsII'' has the Warmth pyromancy, which places a floating ball of fire that periodically heals everything in a small radius around it, including enemies. In the ''Crown of the Old Iron King'' DLC, some of the Ashen Idols use a much stronger version of this pyromancy that ''only'' heals the enemies. [[spoiler:Four of them must be neutralized in order to properly challenge the Fume Knight.]]
* ''VideoGame/EldenRing'' has the "[[FirePurifies Flame, Cleanse Me]]" incantation. It cures both ordinary Poison and, more importantly, is one of the few cures for [[ThePlague the Scarlet Rot]]. It's partially CastFromHitPoints, violently burning the toxins away, but it's far less damaging than the status effects it cures. It also has the unadvertised (and probably unintended) effect of healing Frostbite, since it does that tiny bit of Fire damage to you.
* ''VideoGame/FinalFantasyTacticsAdvance'' and [[VideoGame/FinalFantasyTacticsA2 its sequel]] have an Elementalist spell that counts as Fire-elemental healing. This let it heal undead units (due to not being Holy-elemental) and heal more if the unit was weak to Fire attacks.
* ''VideoGame/GoldenSun''
** The [[PlayingWithFire Mars Adept]] Jenna possess the unique Aura line of spells that heal the entire party and fellow Mars Adept Karst uses it when she is fought. These spells were introduced in the second game to fix an oddity in the first where Karst's sister Menardi used the [[HealItWithWater water-elemental spell Wish]] to heal herself and her partner despite fire and water being opposite elements.
** The ultimate summon spell, Iris, simultaneously causes heavy fire damage to the enemy party and heals the player's party back to full health.
* In ''VideoGame/HeavyRain'', should Ethan cut off part of his finger during the Lizard Trial, the player has the option to cauterize the wound with a heated steel bar. There's a Trophy for doing so.
* In ''VideoGame/Injustice2'', Supergirl uses her heat vision to cauterize Harley Quinn's stab wound inflicted on her by Wonder Woman.
* ''VideoGame/LeagueOfLegends'':
** This is the whole thematic shtick with Milio, [[WhiteMage a support-based champion who uses his fire to heal, cleanse, and empower his allies]] ''far'' more than using it offensively. He places [[ElementalBarrier fiery barriers]] around his allies to buff up their speed and empower their attacks with flame, creates [[FireOfComfort mobile campfires that empowers their attack range]], and his LimitBreak releases a burst of flame that instantly heals surrounding allies and [[HealItWithFire frees them from whatever status effects are inflicted on them]].
** To a lesser extent, [[OurAngelsAreDifferent Kayle]] has the "Celestial Blessing" ability, which heals herself or an ally and gives them a useful burst of speed through purifying [[StarPower starfire]].
* ''VideoGame/LordsOfMagic'' gives the cauterize wound spell, which provides healing.
* Leila Ibuki in ''VideoGame/MagiaRecordPuellaMagiMadokaMagicaSideStory'' can summon flames that can be either used to harm or heal; mechanically, she’s a Fire-type unit with a healing Connect.
* In ''VideoGame/NovaDrift'', the Purification mod can replenish both hull and shield, with the effectiveness of restoration scaling with the number of enemies that are burning.
* The usual ''modus operandi'' of the Purifier [[CombatMedic cleric]] [[BadassPreacher soul]] in ''VideoGame/{{Rift}}''.
* In ''VideoGame/StarStealingPrince'', Snowe is both a powerful user of fire magic and the party's resident healer using "pleasant flames".
* In ''VideoGame/TheSunkenCityCollection'' the Seraph's Cauterize skill cures bleeding from the target and gives them a significant boost to bleed resistance, but also debuffs their speed and causes them to take more stress for a few rounds.
* In the ''VideoGame/TombRaider2013'' reboot, an injured Lara is forced to heal an open wound in her side with this method, using a lighter and an arrowhead. Needless to say, it's incredibly painful, but it does get the job done.
* ''VideoGame/AVeryLongRopeToTheTopOfTheSky'': The Phoenix skill:
--> Revives all allies with sacred fire.
* In ''VideoGame/WarlordsBattlecry'', the [[PlayingWithFire Pyromancy]] spell list has an [[AreaOfEffect AoE]] healing spell called "Cauterize". It heals for 25 HP per spell level within the casting hero's command radius.
* In ''VideoGame/WorldOfWarcraft'', Fire Mages have a passive ability called "Cauterize". It negates an attack that would kill the mage, heals them to 35%, and puts a Fire-typed DamageOverTime effect on them that deals 45% of their maximum health. So, basically, what would be a lethal blow is prevented, but they'll need healing soon anyway. Mages also used to have a spell called Mage Ward (formerly Fire Ward) that absorbed Fire damage, so they could prevent the damage from Cauterize.

* ''WebAnimation/DeathBattle'': In "[[Franchise/StarWars Boba Fett]] vs. Franchise/{{Predator}}", Boba Fett [[spoiler:gets his right arm cut off by the Predator's Smart Disk. He then uses ''[[LaserBlade a lightsaber]]'' to cauterize the wound.]]

* The fisticuffs-loving nomad Darla from ''Webcomic/BicycleBoy'' attempts to [[spoiler:cauterize her hand]] off screen after she [[spoiler:gets shot through her palm]].
* In what might be the only time that [[SociopathicHero Richard]] from ''Webcomic/LookingForGroup'' didn't use magic to murder or torture everything around him, he was cauterizing a wound that [[TheHero Cale]] had suffered to the neck.

[[folder:Western Animation]]
* In the ''WesternAnimation/{{Archer}}'' episode "Bloody Ferlin", Ray's family along with Archer and Cheryl are garrisoned in their home while having a shootout with the police. Cheryl was tasked with cauterizing bullet wounds with a hot fire iron.
* ''WesternAnimation/Castlevania2017'':
** [[Characters/Castlevania2017Protagonists Sypha]] applies fire magic to her right hand to cauterize a nasty tri-clawed wound on her shoulder that Dracula inflicted, she gets it properly treated after the fight, but [[ScarsAreForever the scars still remain.]]
** [[Characters/Castlevania2017DraculasArmy Isaac]] likewise uses the magic flames that sprout on his Forgemaster dagger to cauterize his wounds when he needs to.
* In one episode of ''WesternAnimation/CelebrityDeathmatch,'' Sylvester Stallone (in a nod to the scene noted above) sets off a small pile of gunpowder on his shoulder in order to cauterize a wound given by his opponent, Arnold Schwarzenegger.
* Although many people used it in fanfiction already (such as ''Embers'' and ''Book Five: Legends'', mentioned above), in the ''WesternAnimation/TheLegendOfKorra'' episode "Beginnings, part 1" included a Firebender using their powers to heal Korra, when that had previously been considered exclusive to Waterbending. However, there's a difference, that being that Waterbending heals people physically as well, while Firebending healing is apparently exclusively spiritual, reading chi paths and spiritual energy in a person to diagnose a problem.
* ''WesternAnimation/RickAndMorty'' includes a fight scene where Rick plays laser tag with a gun-toting convict named Jaguar, and they both injure each other. It should be noted that Jaguar was the one lighting gunpowder in his deep shoulder wound [[ItMakesSenseInContext while Rick was stapling the contents of a burger onto his pickle]].

[[folder:Real Life]]
* According to Website/TheOtherWiki, [[http://en.wikipedia.org/wiki/Cauterize cauterization]] is mentioned in the [[http://en.wikipedia.org/wiki/Hippocratic_Corpus Hippocratic Corpus]]. Since Hippocrates was born after 500 B.C., this one is OlderThanFeudalism.
* Cauterization exists in real life, of course, but what makes this stand out as a TV / film trope is how it is so overused. Often it is shown in situations where a real attempt to cauterize would do far more harm than good, in terms of destroying healthy tissue and increasing the risk of infection.
** In RealLife this was the standard practice before the technique of suturing the veins was rediscovered. More often than not, it killed the patient even if the wound wouldn't have. Pouring boiling oil into open wounds is counterproductive, most of the time.
** Among the main problems with cauterization is the very real risk of gangrene. The wound isn't merely closed; the veins and arteries in the area are sealed shut. This can cause more tissues to die from lack of blood, which can turn gangrenous and ultimately require amputation. What it does do, however, is buy the wounded individual time to get to a hospital, which they still have to do.
** Burn wounds are often treated with special military bandages and open holes in, say, the lungs are treated with bandages that seal around the wound preventing air from escaping the lung. While cauterization may help if your hand was cut off, military medical kits have tourniquets for that kind of thing. Cauterization isn't even a last resort for medics nowadays mostly because a tourniquet, while incredibly painful, can usually stay on just long enough [[note]]four hours is the recommended maximum amount of time before the limb starts dying from lack of blood flow. Suddenly releasing a tourniquet after that point might also cause the blood to flow into the area too rapidly and cause a sudden loss of blood pressure, which can also be fatal.[[/note]] for the patient to be evacuated to a field hospital. The best-case scenario for cauterization would be you have alcohol, a blade, some burn salve and/or burn bandages, a way to heat the blade, no time to wait or any place to evacuate to, no tourniquet or sutures, and a missing appendage. In other words, extremely specific circumstances.
** When modern cauterization is used, it is generally electrocauterization - a probe is touched to the indicated spot and heated with an electric current. This avoids things like waving around hot metal next to an oxygen tank. There is also chemical cauterization, where the "burning" is from a reaction between the chemical and the area it is applied to.
* One method that people use to remove leeches from themselves is to burn the leech with a lit cigarette or a cigarette lighter, which will cause it to let go. This is not recommended, since the burned leech will regurgitate its stomach contents into the bite, which creates a risk of infection. It’s better to either pry the leech off VERY gently (you do not want its teeth to be left in the wound) or just wait until it's eaten its fill and drops off by itself.
