Eye of Newt

Go To

"Fillet of a fenny snake,
In the cauldron boil and bake;
Eye of newt and toe of frog,
Wool of bat and tongue of dog,
Adder's fork and blind-worm's sting,
Lizard's leg and owlet's wing,
For a charm of powerful trouble,
Like a hell-broth boil and bubble."
The Three Witches, Macbeth

The material (or immaterial) component you need to call forth a spell, make a Magic Potion or activate a superpower. It's not as simple as just spending Mana, though. You may need to burn a pinch of sulphur, or to sacrifice the soul of your first born child. Either way, you've got to pay the price before you can throw lightning from your fingertips. If the value of what's sacrificed has to equal the value of what's gained, it's Equivalent Exchange.


These components usually fall into one of the following categories, with some overlap:

  • Symbolic items — wedding rings, grave dirt, a pure red rose. Some materials, such as gold and silver, carry heavy symbolic value all by themselves.
  • Items related to your intended victim, recipient or yourself — articles of clothing, treasured trinkets, personal effects, hair, baby teeth, fingernail clippings, fingers, urine samples, blood, etc.
  • Body parts from exotic creatures — sometimes from creatures that don't actually have those body parts (hen's teeth). The more magical the creature the better. A unicorn's horn beats a crocodile's liver, but the blood of a god is better still. Doubly so if it has crystallized. Upping the danger, the creature is sometimes a Monster Lord.
  • Certain plants — again, some are more potent than others. Plants traditionally associated with magic (wolfsbane, nightshade, mandrake, etc) outrank the common blade of grass.
  • Advertisement:
  • Inorganic substances — certain types of rocks, minerals, metals, etc. May have to come from a specific place (e.g. dust from a graveyard or water from the river Styx).
  • Non-physical components — bottled moonlight or the sound of a cat's footsteps.
  • Items with improbably specific requirements — an unripe Sunset Wonder picked 3 minutes before noon on the first frosty day in the autumn and peeled left-handedly using a silver knife with a blade less than half an inch wide.
  • Perishable or fragile items—these are usually put into creating an improbably durable object, such as a gown of cobweb or a necklace of dewdrops. (Which may expire without notice, and very suddenly.)
  • Reusable items — equipment for mixing the ingredients or casting the spell, like a Magic Cauldron or a Magic Wand. Could be as simple as a bowl and spoon, or as complex as an entire alchemical laboratory.

Black Magic often requires ingredients that are a Moral Event Horizon just to collect.

Getting these ingredients may vary in difficulty; the rarer ones often involve going to get a Flower from the Mountaintop or a similarly inaccessible material.

Sometimes this trope is used to justify Plot Coupons as necessary ingredients. Can result in a Gotta Catch 'Em All plot if one spell calls for several items. Improbably specific requirements can be used to set up impossible tasks. If one of the 'ingredients' happens to be the caster's immortal soul, then it's a Deal with the Devil.

A subtrope of Functional Magic, and one part of Spell Construction. Compare with the actual words of the spell, and associated Magical Gestures. Compare also Insert Payment to Use.

Not related in any manner whatsoever, to the former Speaker of the US House of Representatives. Incidentally, "eye of newt" is actually a historic term for mustard seed, although (as evidenced by Shakespeare) confusing the term for the eyes of literal amphibian newts is a very old mistake.

    Anime and Manga 
  • Ranma ½:
    • In the manga, sometimes spell components are needed by the magic users. For example, Happōsai needs the tears of a creature both male and female for a rejuvenation potion.
    • Happens once or twice in the anime, too. In "The Last Days of Happōsai...?", Akane Tendō tries to prepare a magical elixir that will revitalize the dying pervert ++ it's implied her usual lack of skill in the kitchen is the source of the potion's nauseating stink, which eventually renders all of the others in the house bedridden with sickness. Eye of newt and toe of frog are even actual ingredients.
  • In Great Teacher Onizuka, one member of a trio of witch-wannabes drinks a Love Potion and accidentally sees Onizuka first. They try to use black magic to negate the power of the spell. Ingredients include bat wings (procured from the science department), toad warts (ditto), and Onizuka's pubic hair (uh...).

    Comic Books 
  • Asterix: All Getafix will reveal about the ingredients of the magic potion is that it contains mistletoe harvested with a golden sickle and lobster. The lobster is optional, but it improves the flavor. A few other ingredients are revealed through plot contrivance — such as a tiny drop of "rock oil" (petroleum), although through research it is determined that it can be substituted with beetroot juice which has the exact same effect, is easier to get and doesn't taste as bad, and "reasonably fresh fish". It's implied that insofar as its chemistry goes it's really just a mediocre vegetable soup, albeit with added magic effects. Several times its obscure ingredients are used as Plot Coupons, such as in The Black Gold, The Great Crossing, and Asterix in Switzerland (although that was for an ingredient needed to brew an antidote for a poison).

    Comic Strips 

    Fan Works 
  • FFS, I Believe in You: In the sequel, Syrup's magic potion is given an extensive list of ingredients, most of which are specific to the Oracle games and thus fairly difficult for the Breath of the Wild-era characters to identify and track down — a raw mushroom, a fully-cooked rock brisket, five leaves from the Maku Tree, a roc's feather, two petals from a leever, and the liver of a river zora. The liver in particular turns out to be a problem, as the recipe was written when zora were hostile monsters (whereas in the fic's present day they're civilized beings); the direct descendants of the hostile zora are the lizalfos, whose liver may serve as a substitute... except that the lizalfos have just formed a peace treaty with the other races. It's eventually worked out that a specific kind of fish may be substituted.
  • Shadowchasers: Torment: Lampshaded. After Raviel breaks out of prison, the Chicago Shadowchasers follow her to her palace, then become separated. When Nichole finds her laboratory, she finds a lot of weird ingredients on the shelves like "zombie mold", "viper tree fangs", and "troll warts". Eventually she says "Lovely... All that's missing here is the eye of newt..." Then she's interrupted by Raviel's henchman Belger (who may have been watching her for a while) who says, "It vent bad. Ve had to throw it avay. You use bad eye of newt, you ruin zee whole brew."
  • Friendship is Witchcraft: Taken to a rather dark extreme with "Pinkie's Brew"; the "eye of a Newt" turns out to be from the foal Newt Pippington British-hooves.

    Films — Animated 
  • In Snow White and the Seven Dwarfs, the evil queen brews a potion to turn her into a hag with mummy dust to make her old, black of night to change her clothes, an old hag's cackle to alter her voice, a scream of fright to whiten her hair, a blast of wind to fan her hatred, and a thunderbolt to mix all the ingredients together.

    Films — Live-Action 
  • The twins in Double Double Toil And Trouble overhear a group of witches discussing their methods to brewing potions. One of the witches can be heard asking another if she uses a microwave.
  • You know that song the choir's singing near the beginning of Harry Potter and the Prisoner of Azkaban? Taken directly from The Scottish Play. "In the cauldron boil and bake fillet of a fenny snake..." and of course the inevitable something wicked this way comes finish.
  • The film Hocus Pocus uses this trope when the witches produce the potion that enables them to absorb the life force from the children.
  • Parodied in the movie Robin Hood: Men in Tights, where Latrine is apparently putting together a scrying spell with all sorts of gooey ingredients, including "eyeballs of a crocodile". A moment later we learn she's not a witch at all; she's the cook.
  • Warlock used the body fat of a non-baptised child as a levitation potion. Baptise your children, people!

  • Discworld:
    • Magicians sometimes need components to make sure their spells work within the laws of physics. When teleporting, for example, an equal mass is usually displaced from wherever the wizard plans to get to.
    • We often see witch spells requiring ingredients, such as in Wyrd Sisters, a direct sendup of Macbeth which contains a scene parodying the above quote. Granny Weatherwax, for example, complains about using up a "tiger's chaudron" that "looks like perfectly good chitterlin's ... there's hungry children in Klatch who wouldn't turn up their noses at it." And tongue of boot.
    • Furthermore, the cottage Magrat lives in used to belong to a "research witch", who asked questions like "it's all very nice to say 'eye of newt', but what species of newt? And would it still work if you substituted something less icky?" and wrote all her research down in dozens of volumes. (Turns out it works, though: Magrat later uses one such carefully defined spell to find out her boyfriend's first name. She starts working on a love spell too, but plot intervenes before she completes it.)
    • When it comes to magical ingredients, wizards can be divided into the ones who perform the Rite of AshkEnte with two bits of wood and a fresh egg, or the ones who know you can do that, but it's not proper magic unless you're using lots of skulls, ram's horns and dribbly candles.
  • In the Young Wizards series many spells used to require hard to find physical components, but as successive generations of wizards improved the spells the components were changed to easier to find substitutes, and eventually the spells were perfected to the point where they needed no components at all. The modern-day characters which the series follows only rarely have to cast a spell which requires any sort of physical component.
  • In the book The Princess Bride we are told that they had to search for strange components before Miracle Max could do a miracle, but we aren't shown it because it would take too long.
  • Subverted in The Witcher - wizards do display impressive collections of mysterious ingredients all over their labs and everyone knows stories about elixirs made of "blood of virgin killed by bolt of lightning on a cloudless night". It turns that mundane replacements works as well, but wizards encourage gossips since it keeps smallfolk away from carrying on their own experiments.
  • Ingredients in Harry Potter potions include a bezoar and bicorn horn, and the brewing of Polyjuice Potion involved particular parts of a lunar cycle.
    • The spell that resurrected Voldemort in Harry Potter and the Goblet of Fire required "bone of the father, unwillingly given" (Voldemort's father's bone, stolen from the grave), "flesh of the servant, willingly sacrificed" (Wormtail cut off his own hand), and "blood of the enemy, forcibly taken" (cut from Harry's cheek).
  • The Dresden Files sometimes uses non-physical components gathered under specific conditions. For instance, Harry had to be truly happy in order to gather sunlight into a handkerchief.
    • Potions specifically need eight ingredients. A base liquid, an ingredient for each sense and one for the spirit and the mind. A love potion, for example, uses tequila as a base, money for the mind, chocolate for taste, perfume for smell, lace for touch, a sigh for sound, candlelight for sight, and the ashes of a romance novel for spirit (though it probably would have worked a little less sleazily if they hadn't used substitutes for the original base, mind and spirit ingredients — champagne, powdered diamond and the ashes of a love letter).
    • Ordinary magic can be done without physical ingredients or foci, but no-one does it that way. You can just create the things you need in your mind, but if your mental image slips just a little, your spell will fail. Trying to do it that way, rather than with a physical object, is much more difficult and makes no difference in effect, so no-one bothers unless the midden hath hit the windmill, big time.
  • In The Legends of Ethshar series, Ethsharian wizardry uses ingredient like this - a raindrop caught in midair, the blood of an unborn child.
  • One of the characters in Iron Council is a monk from a special order that discovers secrets. To do so, however, the monk has to sacrifice one of his/her own memories or abilities each time he digs up new info.
  • In The Neverending Story, Bastian discovers that every time he uses his amulet to "change" things, he sacrifices one of his own memories. Eventually, he develops full amnesia. He gets better.
  • In Dream of the Red Chamber, Precious Virtue's Cold Perfume Pill has a vast list of peculiar ingredients which are so rare they can only make a batch every twenty years or something.
  • In the Enchanted Forest Chronicles, Cimorene searches in vain for months to find some hen's teeth so that she can complete a spell to protect her against fire (she's employed by dragons). She eventually has to get them from a genie.
  • A couple of books from Kushiel's Legacy use this trope; the end of the first series ('Kushiel's Avatar' I believe) has the bone-priests that only get their power by sacrificing someone that they love. The Mharkagir tries this with Phedre but she kills him instead; and there was much rejoicing.. 'Kushiel's Mercy' (end of the second series) has Carthage trying to take over Terre D'Ange with some pretty involved magic. The stone trapping the elemental has some pretty icky requirements ( infanticide being the big one) and the needle that afflicts Imriel with madness (and thus saves him from the bigger spell the Carthaginians are casting) requires toad-bile, lunatic sweat and being left in the light of the full moon (and NOT being in any other light) for a full month. Wonder what the process was for finding all that out.
  • In Robert E. Howard's Conan the Barbarian story "A Witch Shall Be Born" the title witch does not want this kind of magic.
    I could never endure to seclude myself in a golden tower, and spend the long hours staring into a crystal globe, mumbling over incantations written on serpent's skin in the blood of virgins, poring over musty volumes in forgotten languages.
    It was woven from the tresses of dead women, which I took from their tombs at midnight, and steeped in the deadly wine of the upas tree, to give it strength.
    All discarded portions of the human body still remain part of it, attached to it by intangible connections. The priests of Asura have a dim inkling of this truth, and so all nail trimmings, hair and other waste products of the persons of the royal family are carefully reduced to ashes and the ashes hidden. But at the urgent entreaty of the princess of Khosala, who loved Bhunda Chand vainly, he gave her a lock of his long black hair as a token of remembrance. When my masters decided upon his doom, the lock, in its golden, jewel-encrusted case, was stolen from under her pillow while she slept, and another substituted, so like the first that she never knew the difference. Then the genuine lock travelled by camel caravan up the long, long road to Peshkhauri, thence up the Zhaibar Pass, until it reached the hands of those for whom it was intended.
  • In The Patchwork Girl of Oz, one of L. Frank Baum's Oz books, Ojo is collecting the ingredients to restore people from statues. He is arrested for collecting a six-leafed clover; Ozma made it illegal to collect such ingredients because people refused to obey her anti-magic law. Later, he finds the hardest — a drop of oil from a living man — which is from the Tin Woodman. Alas, he also needs the left wing of a yellow butterfly, and the Tin Woodman refuses to allow a butterfly to be harmed for the spell. Luckily, Glinda the Good doesn't need these ingredients.
  • In L. Jagi Lamplighter's Prospero's Daughter trilogy, phoenix lamps, lit by phoenix feathers, and the Water of Life, retrieved from a well at the edge of world, are the first of many, many, many such items.
  • In War of the Dreaming by John C. Wright, magicians use symbolic objects to compel obedience from the spirits who respond to them—such as moon rocks from the Apollo missions.
  • Played for comedy in A. Glushanovskiy's Road to Mage, first novel of the Way of the Demon series. Oleg, the protagonist, found a spell to detect precious metals underground and already thought of using substitutes for a "dragon's vertebra" - a dinosaur's vertebra from a museum, and for "river-horse hair" - a hair of a tame hippopotamus from the zoo. But he's out of ideas to obtain or substitute "lock of hair from a chaste actress", "spit of a truthful lawyer" and "blood of a honest secretary of state".
  • Willy Wonka's creations aren't magic so much as mad science in action, but in the sequel Charlie and the Great Glass Elevator, the Fountain of Youth pill Wonka-Vite and its Vita-Wonk Rapid Aging counterpart are both made primarily or entirely of such ingredients, some of which are insubstantial ("the hip (and the po and the pot) of a hippopotamus", for instance). Vita-Wonk is made entirely from bits of the oldest animals and trees known to man because they can "create age".
  • In another Roald Dahl book, James and the Giant Peach, there's the formula that created the titular giant peach and the enormous insects that lived in the peach's pit:
    "One thousand long, slimy crocodile tongues boiled in the skull of a dead witch for 40 days and 40 nights. Add the gizard of a pig, the fingers of a young monkey, the beak of a parrot and three spoonfuls of sugar, and then let the moon do the rest."
  • In yet another Roald Dahl book, The Witches, the Grand High Witch tells the other witches the ingredients they need to make their own potion to turn children into mice which include things like the wrong end of a telescope, the fried tails and simmered bodies of forty five mice, and an alarm clock. The alarm clock is to delay the effect of the potion so it can't be traced... and when it activates, the alarm audibly goes off.
  • In Herbert Wells's The Truth About Pyecraft the narrator gives the titular character an Indian magic recipe to loose weight and instructs him on some basic principles:
    I ran my eye over the [list of] items. "Was the egg addled?" I asked.
    "No. Ought it have been?"
    "That," I said, "goes without saying in all my poor dear great-grandmother's recipes. When condition or quality is not specified you must get the worst. She was drastic or nothing..."
  • In The Stormlight Archive, you have to have a gemstone of the appropriate type to perform Soulcasting. So if you want to turn someone into glass, you'd need a diamond. To turn him to stone, you need topaz. Notably, this even applies to Radiant Soulcasting, despite Radiant powers not usually having material components.
  • The ingredients for the oobleck potion in the Dr. Seuss book Bartholomew and the Oobleck.
  • Several scenes in A Night in the Lonesome October show the characters harvesting magical ingredients, which include things like a specific body part stolen from a graveyard under a specific phase of the moon, or a piece of cloth cut from the dress of a red-haired woman (while she's wearing it) at a particular hour of night. The narrator remarks that "Magical rotas sometimes strike me as instructions for lunatic scavenger hunts."

    Live-Action TV 
  • Buffyverse:
    • Obligatory Buffy mention. Various ritual spells require various components, some even require the Eye Of Newt. Although according to the resident witch, eye of frog is cheaper. Really, you're just paying for the brand name. Giles also considers salamander eyes equally effective.
    • In Angel Wesley is analyzing a Fantastic Drug which has PCP-like effects on demons, and mentions that Eye of Newt has been added to improve the taste rather than the kick.
  • Potion ingredients are the plot coupons in The Legend of Dick and Dom; to cure their kingdom from plague, they need to collect two seasons' worth of ingredients like a dragon's clack, the mists of time, baby vampire vomit, and a pint of milk.
  • In Charmed, potions sometimes require these, but good ones usually use more benign herbs.
  • In Supernatural, many rituals and spells require a list of items, such as the photo of the summoner, graveyard dirt, yarrow, and bone of a black cat, required to summon a crossroad demon.
  • In an episode of Friends, Phoebe is helping Rachel and Monica with a ritual to end their bad luck with their love lives that requires some very odd items, most notably "The semen of a righteous man". Rachel and Monica complain that if they had access to that, then they wouldn't be needing the ritual in the first place.
  • On Good Eats, Alton explains how the image of pasta sauce simmering on the stove (stirred lovingly by a mom or grandma) can be a reminder of home and hearth for some...and for others, it brings to mind images of witches and cauldrons. The witch throws in snakes, spiders, etc., while the loving grandmother throws in spices, in an Escalating War, until Alton informs both women that he cooks alone.
  • In The Beverly Hillbillies, Granny is frequently making concoctions like this, brought up by name when the Clampetts visit London and Granny goes to a pharmacy for ingredients. When she mentions Eye of Newt by name, the Pharmacist mistakes her for a fellow Shakespeare fan and wows her with quoting the Bard.
  • In the recurring Saturday Night Live sketch "Theordoric of York, Medieval Barber", Theodoric often prescribes treatments with odd ingredients, such a poulice made of powdered staghorn, gum of arabic, and boiled sheep's urine.

  • Stormwitch song "Stronger Than Heaven" begins with a listing of various magical ingredients.
    Mandrakes, three black feathers
    Dried up toads and rats
    Spiders, human leather
    Eyes and wings of bats

    Tabletop Games 
  • Largely averted for spells in Ars Magica.
    • A standard spell does not require any components.
    • All ritual spells consume vis in order to power the magic. A spell has to be a ritual spell if lasts more than a month, effects an area that is large enough to qualify as a boundary, or a similar target, if it creates something permanently, or if it simply past a certain level.
    • The one time non-ritual spells need a physical component is when it is meant to be cast on someone or something that is not within the caster's senses. This type of component is an arcane connection. It also helps to overcome magic resistance. Again, the item is not consumed.
    • One supplement introduces potent spells that require certain materials to cast a spell. If the caster does not have the material, the spell cannot be cast, but if he or she does have the material, then it grants a bonus to the casting total. The item is still not consumed, however.
    • When making devices that can work magic, the material of the item is considered in determining how much magic it can hold and sometimes provides a bonus to the magus instilling it with magic.
    • Verditius magi create a casting tool when they learn a new formulaic spell. They must use this tool to cast the spell. If it is lost or destroyed, they must spend the time to make another tool for the spell. The tool itself is not consumed in the casting.
  • Dungeons & Dragons: Spellcasting in many versions (D&D 1e, AD&D 2e, and D&D Third Edition) require use of material components. For standard spells, like fireball, this requires something trivial and commonplace (like bat guano and sulfur rolled into a ball). Spells that are particularly powerful or create more permanent effects, such as Raise Dead, can require expensive components, limiting the number of times you can conveniently use them. Depending on how anal retentive the DM is, players might not be expected to keep track of mundane spell components. For those that do, the feat Eschew Materials and prestige classe Runecaster allow players to cast spells without maintaining a laundry list of spell components.
    • 5th edition allows magic users to ignore non-valuable material components, either by using a component pouch (which is assumed to contain the various required components) or a spellcasting focus such as a magic wand or a holy symbol.
  • Warhammer Fantasy Roleplay:
    • Each conventional spell can consume a specific material "ingredient", ranging from a common substance (e.g.: butter) to something rare and/or expensive (e.g.: a ruby). In 1st edition, the ingredient is needed in order to cast the spell. In 2nd, it provides a small bonus to the spellcasting dice roll and is optional (except for the Spirit magic of Hag Witches). In 4th Edition, it's an optional way to reduce the chance of a Magic Misfire.
    • Ritual Magic spells consume thematically linked ingredients that are almost invariably rare, expensive, and/or a Sidequest in and of themselves to obtain. For example, the ritual to cause an earthquake requires a large diamond, a dragon's tooth, and a gong blessed by a dying priest.
  • In Mage: The Awakening extended spellcastings are made easier by the sacrifice of a 'sacrament'; an item metaphorically relevant to the spell being cast (for example, burning a map to create a portal).
    • Also, for Archmasters to cast an Imperial (i.e. godlike) spell, they require a 'Quintessence', a metaphorical component, such as an ingredient or event.
    • "Gross matter", substances which can be imprinted with magic (effectively making potions) can only be manufactured by gathering materials thematically relevant for the kind of gross matter you are trying to make (different kinds can be imprinted with different spells; for example, spells that affect perception need to be imprinted into eye drops), before using a spell to transform it.
  • In Urban Arcana, the modern day Dungeon Punk variant for d20 Modern, a special variant of spellcasting called "Incantations" are available. These Incantations are lengthy yet powerful procedures that require materials appropriate to the spell in question. For instance, demon summoning would likely require a virgin sacrifice and an obsidian knife, whereas the consecration of a building would require holy water and a recitation of prayer.
    • Also, ordinary spells might still require material components, such as a can of soda to make people go faster and the CTRL ALT and DEL keys from a keybord to shut down any electric device in a given radius.
  • Ritual magick in Unknown Armies has this as its great drawback. Rituals may need anything from a scratched brass doorknob to your own eyeball to "acres and acres of burning tires".
  • GURPS Magic mostly handwaves these away: most spells require some sort of unspecified material components, but wizards usually have what they need on hand. The Game Master is advised to elaborate on this if a shortage of a component would help curb abuse of a problematic spell, or just provide plot hooks. GURPS Thaumatology provides optional elaboration on this, and its alternate magic systems go into detail about the use of material components in folklore and fiction.
  • In Changeling: The Lost, hedgespun items are created in and using components taken from the Hedge. These can include the relatively simple, such as vines or shells, or the complex, such as refined metals, but every ingredient needs to have some sort of story behind it, one through which the players take their characters in the process of gathering said components.
  • Shadowrun has "reagents" as an optional part of spellcasting to reduce the drain the caster has to resist and a necessary part of ritual magic. Some rituals also require a material link to the target.

  • The Trope Namer comes from the witches song in Macbeth.
  • The Witch in Into the Woods says she can lift the curse on the Baker if he brings her several items: the cow as white as milk, the cape as red as blood, the hair as yellow as corn, and the slipper as pure as gold. Each of these items, of course, comes from one of the other fairy tales being told.

    Video Games 
  • The Elder Scrolls:
    • A staple of the series is its complex Alchemy system. Alchemy is a magically classed skill portrayed as a type of scientific magic; when you Item Craft potions, you're distilling the ingredients (using a mortar and pestle, retort, etc). However you appear to be extracting the "magic" from them rather than more mundane chemical compounds (some of the in-universe literature even uses this to justify the Health Food trope; chewing certain ingredients releases their basic properties, but not as well as properly mixing them would). Demonstrated in Skyrim that one can eat alchemical components (Toe of Giant, anyone? Yum!) and will experience a limited version of one of the two effects of each ingredient, which serves as a hint for what to combine it with to get which effects in a potion.
    • The Cult of the Ancestor Moth is an Imperial cult based around divining the information contained within the Elder Scrolls, using a ritual known as the Ritual of the Ancestor Moth, at the eventual cost of their sight. By tradition, the members of the Cult are the only ones allowed to possess and read the Elder Scrolls themselves. They receive extensive protective training (in the form of an ancient ritual) to safeguard their bodies and minds against the power of the Scrolls, but even then, repeated readings will eventually strike them permanently blind.
  • WarioWare: Touched!: Ashley's theme song mentions using eye of newt to hex someone. It also mentions grandma's wig, though it's ambiguous whether it's a component or the target of the spell.
  • Ninjas in Final Fantasy XI require ninja tools to perform their ninjutsu spells. The sheer amount of tools used to tank (No, Really), as well as the cost of the other tools make Ninja one of the most expensive jobs in the game.
    • Likewise, Corsairs need elemental cards to fire elemental blasts from their guns.
  • The first three Ultima games had rituals with elaborate requirements for each spell, but they were All There in the Manual. Ultima IV had you manually mixing up spells out of each reagent, typing incantations in the game's Fictionary, and then binding them with a small sacrifice of mana for later casting (with more mana.) Later games kept the reagent system, but did the rituals for you automatically.
  • This is how magic works in The Sims 2. Spells are fueled by objects called reagents that you can either buy or make for free, though making them takes time. Good spells are made with good reagents, such as dragon scales willingly given by an elder dragon, and evil spells are fueled by evil reagents, such as literal Eye Of Newt made by..well take a guess. This is Informed Ability and All There in the Manual, all the sim actually does is stir a cauldron to create the reagents.
  • In Hand of Fate, the second game from The Legend of Kyrandia series, Zanthia has to create potions this way to deal with various obstacles on her way. The ingredients from Zanthia's potion book vary from simple (onion, fluff, cheese) to some surreal (yet the surreal ones are actually subverted, since you always can find a real-world substitutes to them). The eye of newt itself is not present, but still implied: it is stated as one of the components for the Trance Potion (which cannot be crafted in the game, actually), and at one point you can find your own empty package from the eye of newt (you cannot use it plotwise, but this package is an obvious clue on one particular someone that robbed Zanthia's house at the beginning of the game and helps you understand why is everyone in the town from Act 2 are not responding to anything).
  • In King's Quest III, Gwydion has to gather the ingredients from throughout the realm and use them to cast spells, all while fearing that his wizard master may return and smite him. This worked out nicely in the context of an adventure game, where manipulating items is always a core ingredient.
  • World of Warcraft:
    • All you mages know exactly what I'm talking about. "What? You told me to port to Stormwind! Bah, alright, I'll come to Darnassus, but you're gonna pay for the reagents! This costs money, ya know!"
    • All caster classes have a few spells that require physical components; mages' portals are simply the most well-known. Most other ones can bypass this if the character has the appropriate Glyph.
    • The Northend daily quest "Alchemist Apprentice" involves helping the troll alchemist Professor Finklestein make a truth serum, with ingredients that range from normal-sounding (like Icecrown Bottled Water) to unusual (Raptor Claw and Pickled Eagle Egg) to bizarre (Hairy Herring Heads??) to just plain gross (Putrid Pirate Perspiration and Crystallized Hog Snot??).
  • All of the magic in Secret of Evermore revolves around alchemy formulas which each require different regents.
  • In Albion, one of your party's spellcasters requires a special seed to be thrown at target. You buy these or pick from bushes occurring occasionally in wilderness.
  • One of the ways you can gain more magic in Final Fantasy VIII is by refining Vendor Trash into usable spells via a special ability.
  • A potion in A Vampyre Story requires a nightshade blossom, a gargoyle's breath, a virgin's bone, and a literal eye of newt. The first three she manages to scrounge up, but it's the middle of winter, meaning no newts. So she uses the eye from a picture of a newt in a coloring book. This works perfectly.
  • RuneScape has lots of odd ingredients for spells, though baby blue dragon scales, limpwurt roots, white berries, snape grass, red spiders' eggs, and (what else?) the eye of newt are some of the body parts necessary for potions. Then you get the Rag and Bone Man, who asks for some really strange bones. Shoulder bone of a of giant? Tail bones from nine kinds of dragon? Pelvis of a four-legged, magic-casting water creature that dwells in caves? Fibula bone of the third leg on an adult three-legged creature? He wants them all and more. He serves an Eldritch Abomination that wants to rebuild itself with all the bones. Squick.
  • Shows up twice in Pink Panther: Hokus Pokus Pink for 2 different potions:
    • The first potion, to turn Violet into a immortal magical ninja princess mermaid, requires “The only thing living in the saltiest sea”, and “a Princely laugh, specifically the hugest one that has a chilly past”. The magic book does not specify what is needed for the Ninja part, so Pink improvises by adding a black belt to the cauldron.
    • The second potion to counter the effects of the poisonous apple requires “The carrier of the human soul” and “A redhead’s woeful plea”. When the potion fails to work, Pink again improvises, this time by adding some Greek salad.
  • The Interactive Fiction game Fate has you play as a pregnant woman willing to resort to witchcraft to save/better the life of her unborn child. You have access to a grimoire that lists the ingredients you need for certain spells, ranging from relatively simple ones like Sleep (make a solution from a ground pearl and dust from pixie's wings) to complicated and dangerous ones like Greater Gating (summon a demon to bargain with by slitting a goat's throat with a dagger magically empowered by the blood of a slain human being while wearing a silver crown inside a pentagram).
  • In Fire Emblem Awakening, the two resident Dark Mages in the party spend a lot of their time inflicting curses on foes (and occasionally allies). Tharja, generally more down-to-earth but more vindictive of the pair, asks for spell components that can include bat wings, manakete toenail clippings, and a mess of unspecified cursing implements. Henry, meanwhile, specifies that curses and tome-based spells are different, and that his curses require either a piece of the target, willpower, and/or Blood Magic sacrifices. Curses and hexes ultimately fall into Ritual Magic, but the speed of the ritual varies and the ingredients are still often...well, this trope.

    Web Animation 
  • There's a Halloween episode of Homestar Runner that involves Homestar collecting a variety of ingredients for a "witch's brew." Depending upon the choices of the viewer/player, these can involve stank water, essence of doo doo meringue, and powdered Thanksgiving. And Bubs directly references this trope when he says "A little eye of newt, some toe of frog. Baby you got a witch's brew goin'."

  • The dark magic that Hekate does in the Whateley Universe, like her spell in "It's All in the Timing", is exactly this trope.
  • This picture by Helle Jorgensen reminds witches: take necessary steps to prevent possible contamination by unintended components.
  • Some magic in Phaeton requires this, also in a literal sense of the words, Teliha finds Eye of Newt to be a tasty snack and often eats it all before it can be used for magic.

    Web Videos 
  • In the universe of Tales from My D&D Campaign, any long-range teleportation spell requires an "eldritch eye", the eye of a powerful abomination.

    Western Animation 
  • An episode of Jackie Chan Adventures dealing with a Jiangshi had what's probably a parody of the third type - to permanently banish the hopping corpse, Jackie and colleagues were required to take a toadstool from a graveyard, place it in the Jiangshi's own left sock (which, of course, it wasn't about to just hand them), and throw the sock into a river.
    • That's not a parody, people actually believed that, though usually the sock was filled with rocks or soil from the vampire's grave. And yes, Chinese vampires hop.
    • A lot of Uncle's spells in general follow this theme where certain items are needed. The animal location spells each required an item going along with that animal.
      • There's also those dead blow fish and lizards he uses quite often.
  • An episode of American Dragon: Jake Long has Fu Dog using Eye of Newt simply because it's used in so many potions.
  • In a Halloween episode of The Simpsons, Patty and Selma are witches, cooking the classic recipe...
    "Needs more eye of newt."
    "You always want more eye of newt. If it were up to you, the soup would be nothing but Newt Eyes!"
  • In the Donald Duck cartoon "Trick or Treat" Huey, Dewey and Louie enlist the help of a witch to get back at Donald for pranking them. She whips up a potion with quotations from Macbeth, and partway through she leans over to the nephews and says "This is the real stuff, you know. Right out of Shakespeare."
  • Animaniacs
    • In "Spell-Bound" (which was, incidentally, the first half-hour episode starring Pinky and the Brain exclusively) the first four ingredients for Brain's “Take Over the World Spell” are six lizard legs, two eyes of newt, two hedgehog spleens, and one half-eaten gingerbread cookie that’s been left on the counter overnight. (Getting the final ingredient, a red dragon toenail clipping, is the main plot.)
    • In this short, Yakko provides his own, uh, unique interpretation of the original witches recipe, provided for viewers who - like himself and the three characters depicting the witches - have no idea what it means.
  • In Disenchantment, as part of his experimentations with using Elfo's blood in the pursuit of the creation of the Elixir of Life, Sorcerio attempted using eye of newt in the brew, along with tail of newt and rest of newt. This ended up creating a truth serum.
  • In the Arthur music video "Jekyll and Hyde", the ingredients for the Brain's turn-into-Mr.-Hyde potion include "dirt, a bit of sludge, some eyes of flies, and a tiny dab of suntan lotion".

    Real Life 
  • Hoodoo folk magic is made of this trope. Components can include (but are by no means limited to) red brick dust, graveyard dirt (preferably from the grave of a soldier or a child. Or, for best results, a Child Soldier), coffin nails, dried bat hearts, and raccoon penis bones, not to mention various bodily fluids. Much of the lore comes down from rural areas in the 1930's, when such ingredients were much easier to obtain than they would be today (or not: a random Google search can and will turn up various shops selling such items online, many disturbingly authentic).
