Geranium Essential Oil: Benefits, Uses, Blends and Safety
Geranium essential oil is steam distilled from the leaves and stalks of Pelargonium graveolens and its hybrids, giving a rose-like scent with a green, minty edge that no garden geranium actually produces. This guide covers geranium oil benefits, everyday uses, dilution rates, blending partners, its Venus and heart chakra associations, and the geranium oil safety cautions that matter most, including cats, pregnancy and sensitization from oxidized bottles.
What is geranium essential oil and how is it extracted?
Geranium essential oil is steam distilled from the leaves and stalks of Pelargonium graveolens and closely related scented pelargonium hybrids, not from the flowers and not from the true geraniums of the genus Geranium that gardeners call cranesbills. The plant is a shrubby South African native with soft, deeply cut, strongly aromatic leaves, and almost all of the oil sits in glandular hairs on the foliage rather than in the small pink blooms. Growers cut the crop just before or at the very start of flowering, when leaf oil content peaks, and distill the wilted herb for around two to three hours. Yields are low: several hundred kilograms of leafy material go into a single kilogram of oil, which is why geranium essential oil sits in the mid price band rather than alongside cheap citrus. The finished oil runs pale olive to greenish amber and is thin and free flowing. Commercial production centers on Egypt, China, South Africa, Madagascar and the island of Reunion, and the growing region shapes the aroma more decisively than the botanical name on the label, because most commercial stock is hybrid and propagated from cuttings rather than seed.
Naming is the single most confusing thing about geranium essential oil, and it pays to understand it before buying. Suppliers sell oil under Pelargonium graveolens, Pelargonium roseum, Pelargonium capitatum x radens and simply Pelargonium asperum, and these labels overlap so heavily in the trade that they behave more like commercial grades than reliable botanical distinctions. What actually varies is the ratio of citronellol to geraniol, plus the level of isomenthone and the sesquiterpene fraction, and that ratio is set by cultivar, altitude, harvest timing and distillation practice. Bourbon geranium, grown on Reunion, was established there during the French colonial period and remains the connoisseur's grade: complex, minty and slightly earthy, and priced accordingly. Egyptian geranium dominates volume, is rounder and rosier, and is the default in most aromatherapy shops. Chinese geranium is cheapest and sharpest. Rose geranium is the geraniol-forward selection prized by perfumers. None of these is inferior for practical aromatherapy, but if a blend depends on a particular character, buy by origin and smell the batch rather than trusting the Latin binomial alone.
Is geranium essential oil the same as rose geranium oil?
Geranium essential oil and rose geranium oil come from the same group of scented pelargoniums but differ in chemistry. Rose geranium is distilled from geraniol-rich cultivars, so it smells sweeter and closer to rose otto, while standard geranium essential oil leans toward citronellol with a mintier bite. They are interchangeable in use and identical in safety terms.
Where does Bourbon geranium essential oil come from?
Bourbon geranium essential oil comes from Reunion, the Indian Ocean island formerly called Ile Bourbon, where the crop was established under French colonial cultivation. Bourbon geranium is the most prized commercial grade, with a mintier, more layered and faintly earthy profile than Egyptian or Chinese material. Genuine Reunion production is small, so much oil sold as Bourbon is Egyptian in origin.
How can you tell if geranium essential oil has been adulterated?
Geranium essential oil is one of the most routinely adulterated oils, usually stretched with citronella fractions, synthetic geraniol and citronellol, or cheap Chinese oil sold as Bourbon. Warning signs are a suspiciously low price, a flat one-note rose smell with no minty green lift, and a harsh lemony sharpness. Ask for a batch-specific gas chromatography report rather than a generic one.
What does geranium essential oil smell like?
Geranium essential oil smells like rose crossed with crushed green leaf and a cool minty snap. The rose impression comes from citronellol and geraniol, the two dominant alcohols, and it is genuinely rose-like rather than merely floral, which is why geranium has served for over a century as a legitimate extender for rose otto and an illegitimate adulterant of it. Sitting under that rose is isomenthone, a ketone that supplies the peppermint-adjacent sharpness people either love or find soapy, and above it a light citrus-lemony flicker from citronellyl and geranyl formates. The dry-down turns quieter and slightly damp, a stem-and-soil quality most obvious in Bourbon geranium, where sesquiterpenes give the base a faintly woody, mushroom-edged softness. Compared to rose otto, geranium essential oil is thinner, greener and less honeyed, without the deep waxy sweetness of true rose. Compared to palmarosa, which shares heavy geraniol content, geranium is far less soapy and much more complex. The overall impression is clean, bracing and slightly astringent, which is exactly why it reads as a skin-care smell to most people rather than a perfume smell.
Geranium essential oil behaves as a middle note with unusually good staying power for its class, holding recognizably on a scent strip for several hours and lingering in a blend long after citrus tops have gone. Perfumery has leaned on that persistence for a long time. Geranium is a structural component of the fougere family, sitting in the heart alongside lavender, coumarin and oakmoss, an accord that traces back to Houbigant's Fougere Royale in 1882 and that runs through most of what people now call a barbershop or classic masculine fragrance. It is equally at home in chypre constructions, where its green astringency stops the mossy base from turning sweet. In a domestic blend this translates into a practical rule: geranium essential oil is a connector rather than a soloist. Put it between a citrus top and a woody or resinous base and it stitches them together, lending body to the citrus and lifting the base. Used alone at full strength in a diffuser it can turn insistent and slightly metallic within twenty minutes, so restraint improves it noticeably.
Is geranium essential oil a top, middle or base note?
Geranium essential oil is a middle note, sitting in the heart of a blend with lavender and clary sage. It evaporates more slowly than citrus or eucalyptus but far faster than patchouli or vetiver, and it remains detectable on a scent strip for several hours. Perfumers value that tenacity, which lets geranium bridge bright tops and heavy woody bases.
Why does geranium essential oil smell minty?
Geranium essential oil smells minty because of isomenthone, a ketone structurally related to the menthone found in peppermint. Isomenthone is most prominent in Bourbon geranium from Reunion and least prominent in geraniol-forward rose geranium cultivars. That cool, slightly medicinal snap is what separates geranium from palmarosa and stops the oil reading as simple soapy rose.
Does geranium essential oil smell like rose?
Geranium essential oil smells convincingly rose-like because it shares citronellol and geraniol with rose otto, and it has been used as a rose extender and adulterant for well over a century. The difference is depth: rose otto carries waxy, honeyed and spicy facets that geranium lacks, while geranium adds a green, minty, stem-like edge that real rose does not have.
What are the main geranium oil benefits?
The main geranium oil benefits fall into four areas: skin balancing, insect repellence, antimicrobial action and emotional steadying. On skin, geranium essential oil is prized as a sebum regulator, valued by people whose faces are oily across the forehead and nose but tight and flaky elsewhere, because it is astringent without stripping. Folk practice also treats it as a styptic, dabbed diluted on shaving nicks and small cuts, and as an ally for scars, broken capillaries and dull mature skin. Its geraniol and citronellol content underpins documented repellent activity against mosquitoes and ticks, and geranium is a standard component of botanical repellent formulas rather than a folk substitute. Laboratory work has repeatedly shown activity against Candida species and dermatophytes, the fungi behind athlete's foot and ringworm, which is why geranium turns up in foot blends beside tea tree. On the emotional side, aromatherapy treats geranium essential oil as the great evener-out, the oil reached for when someone swings between wired and flat, and small clinical trials have examined geranium inhalation for anxiety during labor and for symptoms around menopause.
The claim that follows geranium essential oil everywhere is that it balances hormones, and it is worth being precise about what that means. Geranium contains no hormones and no compounds that behave like human hormones in any meaningful dose from inhalation or a 2 percent massage oil. What the tradition actually records is that people using geranium report feeling less volatile through the premenstrual week and through perimenopause, that it eases the fluid-heavy, heavy-legged feeling many describe at those times, and that it pairs well in massage with clary sage for the same purposes. Aromatherapists also give it a place in lymphatic and circulatory work, using it in slow drainage massage for puffy ankles and sluggish legs, a use rooted in the oil's astringent reputation rather than in trial evidence. Read the benefits accordingly. Geranium essential oil is a genuinely useful skin and repellent oil with real antimicrobial activity in the lab, and a well-regarded mood oil in practice. It is not an endocrine treatment, and anyone with a diagnosed hormonal condition should treat it as comfort care alongside medical management, not instead of it.
Is geranium essential oil good for your face?
Geranium essential oil suits combination and blemish-prone faces particularly well, because it is astringent enough to temper oiliness without the drying effect of stronger antimicrobials. Aromatherapists use it at 1 percent, around five drops in 30 ml of jojoba or rosehip, often with lavender. Sensitive, rosacea-prone or already reactive skin tolerates it less well and should patch test first.
Does geranium essential oil repel mosquitoes and ticks?
Geranium essential oil repels mosquitoes and ticks to a useful but short-lived degree, thanks to geraniol and citronellol, which appear in commercial plant-based repellents. Geranium-derived repellents are marketed specifically for ticks. Reapply every hour or two, blend with lemongrass or cedarwood for better coverage, and use a conventional repellent where mosquito-borne disease is a genuine risk.
Does geranium essential oil balance hormones?
Geranium essential oil does not contain or act as hormones, so it cannot correct an endocrine problem. What aromatherapy tradition records is that people find it steadying through the premenstrual week and around menopause, and that inhaled geranium has been studied in small trials for anxiety in those contexts. Treat it as supportive comfort rather than hormonal treatment.
What are the most common geranium oil uses at home?
The most common geranium oil uses at home are a 1 percent facial oil, an insect repellent spray, a foot blend for fungal problems, an oily-scalp hair rinse, a natural deodorant and a balancing diffuser blend. For the face, five drops of geranium essential oil in 30 ml of jojoba, applied to damp skin at night, is the classic combination-skin treatment. For repellent, 20 drops of geranium with 15 of lemongrass and 10 of cedarwood in 100 ml of witch hazel and fractionated coconut makes a workable spray that needs shaking and reapplication. For feet, six drops of geranium and six of tea tree in 30 ml of a light carrier, worked in nightly, addresses the itchy, peeling skin between toes. A scalp rinse of four drops of geranium essential oil stirred into 500 ml of cool water with a splash of apple cider vinegar suits hair that goes limp and greasy by day two. Two to four drops in a diffuser is enough for a normal room. Geranium also works in a linen spray, a drawer sachet against moths and an aftershave splash where its styptic reputation and clean rose-green smell both earn their place.
Two more geranium oil uses are worth spelling out because they are frequently done badly. The first is the bath. Geranium essential oil will not dissolve in bath water, and drops floating on the surface land undiluted on the most sensitive skin you own. Stir four to six drops into a tablespoon of unscented liquid castile soap, whole milk or a bath oil base first, then add that to a full tub. The second is the PMS or perimenopause massage oil, which is where geranium is most often reached for and most often over-dosed. A useful working blend is 10 ml of jojoba or sweet almond with three drops of geranium essential oil, two of clary sage and one of sweet orange, massaged in slow circles over the lower belly and lower back. That comes to roughly 3 percent, appropriate for short-term local use rather than daily all-over application. For an inhaler stick, six to eight drops on the cotton wick lasts weeks and gives you geranium on demand without scenting a shared office, which suits its slightly polarizing minty edge.
How many drops of geranium essential oil go in a diffuser?
Two to four drops of geranium essential oil suit a standard 100 to 150 ml ultrasonic diffuser in an average room. Geranium is tenacious and can turn insistent and slightly metallic when overdone, so start at two. Run the diffuser in 30 minute bursts rather than continuously, and keep the door open if a cat, dog or bird shares the space.
Can you put geranium essential oil in a bath?
Geranium essential oil can go in a bath only after it is dispersed. Stir four to six drops into a tablespoon of unscented castile soap, whole milk or a bath oil base, then add that to a filled tub. Dropped straight into water, geranium floats undiluted and contacts genital and other delicate skin at full strength, a common cause of stinging and reactions.
Is geranium essential oil good for hair?
Geranium essential oil suits oily scalps and limp hair because of its astringent character. Stir four drops into 500 ml of cool water with a splash of apple cider vinegar as a final rinse, or add three drops to a 30 ml portion of conditioner. For dry ends, use it in a jojoba pre-wash mask at 1 percent instead, where it perfumes without stripping.
How do you dilute geranium essential oil correctly?
Dilute geranium essential oil to 1 percent for facial use, 2 percent for general body and massage work, and no more than 3 percent for short-term local applications such as a fungal foot blend or a premenstrual belly massage. In practical drops that means five to six drops of geranium essential oil per 30 ml of carrier for a 1 percent face oil, ten to twelve drops per 30 ml for 2 percent, and fifteen to eighteen for 3 percent. Children over two, adults over seventy and anyone with reactive skin should stay at 0.5 to 1 percent, which is two to five drops per 30 ml. Geranium is not an oil to be generous with, because geraniol and citronellol are cumulative sensitizers and the people most drawn to geranium tend to be the ones using it daily on the face. Always patch test a new bottle: apply the diluted blend to the inner forearm, leave it 24 to 48 hours, and check for redness or itching before putting it anywhere near your face. Never add geranium essential oil to plain water for a spray without a solubilizer, because it will not disperse and the last spritz delivers the concentrate.
Carrier choice changes how geranium essential oil performs more than most people expect. Jojoba, technically a liquid wax, is the standard base for facial work because it is light, stable and does not go rancid, and its own faint nuttiness stays out of geranium's way. Rosehip seed oil pairs well for scarring and mature skin but oxidizes quickly, so keep those blends small and refrigerated. Apricot kernel and grapeseed suit body massage where you want slip without heaviness. Fractionated coconut is the right choice for repellent sprays and roller bottles because it stays liquid, has almost no odor and washes out of clothes. Unscented lotion works well for hands and legs, and geranium disperses into it easily thanks to its alcohol-rich chemistry. Avoid unrefined coconut oil and heavily scented carriers such as sesame or hemp, which fight geranium's green-rose profile. One practical note on measurement: essential oil drops vary with orifice reducer and viscosity, and geranium is thin, so its drops run small. If accuracy matters, especially for facial blends, weigh the oil or use a graduated pipette rather than counting.
How many drops of geranium essential oil per ounce of carrier oil?
Use five to six drops of geranium essential oil per ounce, roughly 30 ml, of carrier for a 1 percent facial blend, ten to twelve drops for a 2 percent body blend, and fifteen to eighteen drops for a 3 percent short-term local blend. Geranium is thin and drops run small, so weighing the oil gives more consistent results than counting.
Can you apply geranium essential oil undiluted?
Geranium essential oil should not be applied undiluted. Its geraniol and citronellol are recognized fragrance allergens, and repeated neat use is a reliable route to a permanent allergy that will also rule out palmarosa, citronella and rose. The only common exception people cite, a single dab on a shaving nick, still carries real sensitization risk and is better done at 3 percent.
Which carrier oils work best with geranium essential oil?
Jojoba is the best all-round carrier for geranium essential oil on the face, being light, stable and nearly odorless. Rosehip seed suits scar and mature-skin blends but oxidizes fast. Apricot kernel and grapeseed work for body massage, and fractionated coconut is ideal for repellent sprays and roller bottles. Avoid strongly scented carriers such as unrefined sesame or hemp.
Which oils blend well with geranium, and what are the best geranium oil blends?
Geranium essential oil blends well with lavender, clary sage, bergamot, sweet orange, grapefruit, patchouli, sandalwood, cedarwood, vetiver, rose, jasmine, neroli, juniper berry, black pepper, basil and lemongrass. Four geranium oil blends cover most household needs. For a floral diffuser blend, use three drops of geranium, three of bergamot, one of patchouli and one of rose or palmarosa, which builds a rounded rose garden effect from inexpensive materials. For a barbershop room blend, use four drops of lavender, two of geranium, three of cedarwood and one of black pepper, which reconstructs the classic fougere heart in miniature. For a balancing roller bottle in 10 ml of jojoba, use four drops of geranium essential oil, three of clary sage and three of sweet orange. For a repellent spray in 100 ml, use 20 drops of geranium, 15 of lemongrass, 10 of cedarwood and five of lavender in a witch hazel and fractionated coconut base. In every one of these, geranium is the connector holding brighter and heavier materials together rather than the loudest voice.
There are combinations worth avoiding too. Doubling up on geraniol-rich oils, particularly geranium with a heavy hand of palmarosa or citronella, flattens the blend into a soapy, one-dimensional rose that smells like cleaning product. Strong camphoraceous oils, especially eucalyptus, cajeput and camphor-type rosemary, bulldoze geranium's floral character and leave only the minty ketone note, so if you want geranium in a respiratory blend keep it to a single drop as a rounding agent. Very heavy sweet absolutes such as benzoin can smother it as well. The proportions that reliably work put geranium at roughly 10 to 25 percent of the total drop count. Above about a third it starts to dominate and reads sharp; below a tenth it disappears. When extending rose absolute or rose otto, which are expensive enough that most people use them sparingly, one drop of rose to two or three of geranium essential oil produces something that still smells clearly of rose while stretching the costly material. Perfumers have done exactly this for generations, and doing it deliberately in a home blend is legitimate craft rather than adulteration.
What blends well with geranium for a floral diffuser blend?
For a floral diffuser blend, combine three drops of geranium essential oil with three of bergamot, one of patchouli and one of rose or palmarosa. Geranium supplies the rose body, bergamot lifts it, and patchouli anchors the base. Lavender, clary sage, neroli and jasmine also sit comfortably with geranium, while sandalwood gives a softer, creamier version of the same structure.
Does geranium essential oil blend with citrus oils?
Geranium essential oil blends beautifully with citrus, and the pairing is one of the most reliable in aromatherapy. Bergamot is the classic partner, grapefruit gives a crisper result and sweet orange a warmer, rounder one. Geranium gives citrus the staying power it lacks on its own, holding the blend together long after the top notes have evaporated.
Which oils overpower geranium essential oil?
Eucalyptus, cajeput, camphor-type rosemary and clove bud all overpower geranium essential oil, stripping out its rose character and leaving only the minty ketone edge. Heavy palmarosa or citronella causes a different problem, doubling the geraniol and flattening the blend into soap. Keep geranium at roughly 10 to 25 percent of a blend's total drop count for balance.
What are the spiritual and chakra associations of geranium essential oil?
Geranium essential oil is ruled by Venus in the correspondence tables used across modern magical and energetic practice, and it is worked primarily with the heart chakra, anahata. The Venus attribution follows from the rose-like scent, the association with love, beauty and reconciliation, and the plant's soft, rounded, strongly scented leaf. Most practitioners assign geranium to water as its element, though a minority give it earth on the grounds that the oil comes from leaf and stem rather than bloom and carries that damp, green, rooted undertone. On the chakra map, geranium sits at the heart because it works the territory of self-worth, grief and the ability to receive care as well as give it, and a secondary sacral association shows up in blends aimed at cycles, fertility and creative flow. In older European folk practice, potted red geraniums were kept at doorsteps and windows as a household protection, a custom that still shapes how the oil is read: geranium is treated as a guardian of the domestic sphere, an oil for the threshold and for the emotional weather inside a home rather than for grand ceremonial work.
In practice, geranium essential oil is used in three recognizable ways. The first is self-acceptance work, where a single drop diluted in jojoba is anointed over the sternum before mirror practice, journaling about self-worth, or any exercise aimed at softening the internal critic. The second is boundary and reconciliation work, which sounds contradictory until you notice that geranium's reputation is for evenness rather than opening: practitioners reach for it when a relationship needs steadying rather than intensifying, which is why it appears in blends for family houses and shared living spaces instead of seduction blends, where jasmine and ylang ylang do that job. The third is protection of the home, the direct descendant of the doorstep geranium, expressed now as a floor wash or threshold spray with geranium, cedarwood and a little lemon. Friday, the day of Venus, is the traditional timing, and the waxing moon is favored for drawing and the waning moon for clearing. Green and soft rose-pink are the colors most often paired with geranium on an altar, matching both the leaf and the scent.
What planet rules geranium essential oil?
Venus rules geranium essential oil in the standard correspondence tables, alongside rose, ylang ylang and vervain. The attribution rests on the rose-like scent, the plant's soft aromatic leaf and its long association with love, beauty, reconciliation and household happiness. Friday, the day of Venus, is the traditional timing for work involving geranium essential oil.
Which chakra does geranium essential oil work with?
Geranium essential oil works primarily with the heart chakra, anahata, covering self-worth, grief, forgiveness and the ability to receive care rather than only give it. A secondary sacral chakra association appears in blends addressing cycles, fertility and creative flow. Practitioners anoint a diluted drop over the sternum, or diffuse geranium during heart-centered meditation.
How is geranium essential oil used in ritual and spellwork?
Geranium essential oil is used in ritual for household protection, fertility, love-drawing and emotional steadying. Common forms are a threshold spray or floor wash with geranium and cedarwood, a diluted anointing oil over the heart, and a few drops on a green or rose-pink candle dressed for reconciliation. The doorstep red geranium of European folk practice is its direct ancestor.
What are the geranium oil safety cautions?
The central geranium oil safety concern is skin sensitization, not toxicity. Geraniol, citronellol and linalool all appear on the European list of declarable fragrance allergens, and geranium essential oil is rich in the first two. Sensitization is cumulative and permanent: once someone reacts to geraniol, palmarosa, citronella, rose and many perfumed products become problems as well. Oxidized oil is markedly worse than fresh, so storage is a safety measure rather than a housekeeping detail. Keep geranium essential oil tightly capped in amber glass in a cool dark place, use it within two to three years, and decant to smaller bottles as the level falls. People with a known fragrance allergy or balsam of Peru sensitivity should approach geranium cautiously or avoid it. Safety references also flag a theoretical interaction with blood-sugar-lowering medication, so anyone managing diabetes should mention geranium use to their prescriber before adopting large or daily applications. Geranium essential oil is not for internal use outside qualified clinical supervision, must be kept away from the eyes and mucous membranes, and should be stored out of children's reach, since a swallowed bottle is a genuine poisoning risk.
The good news about geranium essential oil safety is what is absent from the list. Geranium is steam distilled, contains no furocoumarins and is not phototoxic, so a diluted geranium blend can be worn before sun exposure without the burn risk that comes with expressed bergamot, lemon or lime. It carries no neurotoxicity warning of the kind attached to camphor-rich or high-ketone oils, and its isomenthone content is not at a level that raises the concerns associated with pennyroyal or sage. Standard guidance places geranium among the oils considered acceptable in low dilution during pregnancy after the first trimester and during breastfeeding, though it is sensible to run any plan past a midwife and to keep to 1 percent. For children over two, 0.5 percent is the usual ceiling, and geranium is not applied to infants at all. Animals are the sharpest limit. The ASPCA lists Pelargonium as toxic to cats, dogs and horses, cats clear these constituents poorly, and birds have respiratory systems that make any diffused essential oil a real hazard. Diffuse briefly, ventilate well, and give every animal a way out of the room.
Is geranium essential oil safe during pregnancy?
Geranium essential oil is generally regarded as acceptable in low dilution after the first trimester, with no reproductive toxicity attached to it in standard safety references. Keep to 1 percent or below, favor inhalation over extensive skin application, and clear it with a midwife or doctor first. Inhaled geranium has been studied in small trials for anxiety during labor.
Is geranium essential oil safe for cats and dogs?
Geranium essential oil is not safe for cats, and caution applies with dogs. The ASPCA lists Pelargonium as toxic to cats, dogs and horses, and cats lack the liver pathway needed to clear many essential oil constituents efficiently. Never apply it to a pet or add it to bedding, diffuse only briefly in a ventilated room, and keep birds out of the space entirely.
Does geranium essential oil cause photosensitivity?
Geranium essential oil does not cause photosensitivity. It is steam distilled from leaf and stalk and contains no furocoumarins, the compounds responsible for the phototoxicity of expressed bergamot, lemon, lime and bitter orange. A diluted geranium blend can be applied before sun exposure without burn risk, which makes it a useful floral substitute in daytime and summer skin blends.
Frequently Asked Questions
What is geranium essential oil used for?
Geranium essential oil is used mainly for skin care, insect repellence and emotional balance. On skin it is added at 1 percent to facial oils for combination and blemish-prone complexions, because it is astringent without being drying. In repellent sprays its geraniol content earns it a place alongside lemongrass and cedarwood. In diffusers and inhalers it is chosen for a settled, evened-out mood, which is why geranium essential oil turns up so often in blends aimed at PMS, perimenopause and irritable, wrung-out days. Perfumers use it as a rose-toned heart note in fougere and barbershop accords.
Can you put geranium essential oil directly on your skin?
No, geranium essential oil should not be applied undiluted to skin. It is rich in geraniol and citronellol, two alcohols that are recognized fragrance allergens and become considerably more sensitizing once the oil has oxidized. Repeated neat application is one of the reliable ways to develop a lasting allergy to geranium essential oil and to every other geraniol-rich oil, including palmarosa and rose. Dilute to 1 percent for the face, 2 percent for general body use, and up to 3 percent for a short-term local application such as a fungal nail or a stubborn spot.
What does geranium essential oil smell like?
Geranium essential oil smells like a rose that has been rinsed in cold water and set on a green stem. The rose character comes from citronellol and geraniol, the sharp minty lift from isomenthone, and the damp, faintly earthy undertone from sesquiterpenes that are most obvious in Bourbon geranium from Reunion. Egyptian geranium reads rosier and softer, Chinese geranium reads sharper and more citronella-like, and rose geranium, distilled from geraniol-rich cultivars, is the sweetest and most convincingly floral of the group.
What is the difference between geranium and rose geranium essential oil?
The difference between geranium and rose geranium essential oil is chemistry and cultivar, not species. Rose geranium is distilled from Pelargonium roseum types and geraniol-leaning cultivars, so it carries more geraniol relative to citronellol and smells noticeably sweeter and closer to rose otto. Plain geranium essential oil, often Egyptian or Chinese, leans citronellol-forward with more of the minty isomenthone bite. Both are used the same way and share the same safety profile. Rose geranium simply costs more and works better where you want a rose impression.
Does geranium essential oil repel mosquitoes?
Geranium essential oil does repel mosquitoes to a degree, because geraniol and citronellol are among the better documented plant-derived repellent molecules and appear in commercial botanical repellents. Geranium is also a common ingredient in tick-repellent formulas aimed at people and clothing. What it will not do is match the duration of DEET or picaridin. A geranium essential oil repellent needs reapplying roughly every hour or two, works best combined with lemongrass or cedarwood, and should never be relied on where mosquito-borne disease is a serious risk.
Is geranium essential oil safe to diffuse around cats?
Geranium essential oil is not considered safe around cats and should be kept well away from them. The ASPCA lists Pelargonium plants as toxic to cats, dogs and horses, and cats are additionally poor at glucuronidation, the liver pathway used to clear many essential oil constituents. Never apply geranium essential oil to a cat, never put it in a cat's water or on bedding, and if you diffuse it, use a small amount in a ventilated room the cat can leave. Birds are more sensitive again and should not be in a diffused space at all.
Does geranium essential oil expire?
Geranium essential oil keeps two to three years unopened and closer to two once the bottle has been broached. It is an alcohol-rich oil rather than a monoterpene-heavy citrus, so it does not turn as fast as lemon, but geraniol and citronellol oxidize into compounds that are more sensitizing than the fresh oil. The warning signs are a flattened, slightly stale rose note and a sharper, almost sour edge. Store geranium essential oil in a tightly capped amber bottle in a cool dark cupboard, and decant into smaller bottles as the level drops.
