Ginger Oil
Zingiber officinale Roscoe · also called Ginger essential oil, ginger root oil
Ginger oil is the strong, spicy-smelling oil from ginger root. People breathe it in for nausea or rub it, diluted, into sore joints. Small trials suggest the scent may ease nausea after surgery and massage may ease some knee and back pain, but the studies are small and easy to unblind. The main caution: never swallow the oil, dilute it before it touches skin, and keep it from children and pets.

About Ginger Oil
Ginger oil is the concentrated essential oil of ginger root. It is breathed in or used diluted in massage. Small trials suggest the scent may ease nausea after surgery and massage may ease knee and back pain for a while. Safety comes first: do not swallow it, it can cause skin allergy, and strong oils can poison pets.
What ginger oil is
Ginger oil comes from the rhizome (root) of Zingiber officinale Roscoe, in the ginger family, Zingiberaceae (name checked in GBIF). The papers we read do not describe how each oil was made.
Lab analyses of different samples found mostly zingiberene (17% to 31%), plus compounds such as citral (geranial and neral), camphene and farnesene. Samples differ.
Some bottles called ginger oil are plant oils infused with ginger. They are a different product, not tested in these trials.
What people use it for, and how strong the evidence is
The best-studied use is the scent for nausea after surgery, with three small trials and a broader aromatherapy meta-analysis. For chemotherapy nausea the result is mixed. Massage with ginger oil has small, short trials for knee pain and back pain. Constipation and menopause have too little evidence. Lab findings on germs and inflammation are not human results.
These are not instructions. This page does not tell you how much to use or how to apply it.
The research in one view
Most trials are small, short and hard to blind, because ginger smells strong. Several used blends of oils, or compared the oil with a different massage, so the oil's own part is unclear. Some abstracts give no numbers. One author on the breast surgery trial reports a tie to a breast-implant company. No large, independent trial of ginger oil alone exists in what we read.
Ginger oil, ginger root, tea and capsules are different things
The European Medicines Agency assessment for ginger covers powdered root and tincture taken by mouth; the essential oil is not mentioned. Trials of ginger tea, root or capsules do not tell us about the oil, and the oil's results do not apply to the root. A narrative review of ginger pain trials mostly covers oral and topical ginger, with one oil massage trial.
What authorities say
The FDA says an aromatherapy product's intended use decides whether it is a cosmetic or a drug, and that claims to relieve pain or help sleep make it a drug. Poison Control and Pet Poison Helpline give the general warnings above. We did not read a ginger-oil-specific statement from any regulator, and we could not read the Tisserand Institute, LiverTox or LactMed.

Isolated compounds versus whole extracts
Ginger oil is the concentrated volatile part of the root. The root, tea and capsules contain many other substances, and the trials of those products do not apply to the oil. The oil research here is small scent and massage trials and lab work.
Nutritional composition
Ginger oil is not a food or a nutrient. Ginger root as a food is covered on its own pages.

Nausea and vomiting after surgery (ginger oil inhaled)
Low certaintyThree small trials found less nausea after surgery when people breathed in ginger oil: one in Korea after abdominal surgery, one in Turkey after thyroid surgery, and one in Japan using a three-oil blend. They are small, people can smell what they get, and one was not randomised. Treat it as a hopeful signal, not proof.
3 studiesNot covered. This page gives no amounts and no ways of using the oil.
Studies, doses and limits
What the trials found
Korea 2017: 60 adults after abdominal surgery, ginger oil inhaled versus saline inhaled (not randomised). Turkey 2025: patients after thyroid surgery, ginger oil versus peppermint versus routine care. Japan 2025: 182 people after oral surgery, a ginger, peppermint and lavender blend versus water.
Results
Korea: nausea and vomiting scores significantly lower with ginger oil, biggest drop in the first 6 hours. Turkey: nausea and pain lower than routine care (Rhodes 1-item score 0.48 ginger, 1.11 peppermint, 1.37 routine care, P < .001). Japan: nausea severity fell more with the blend (p < 0.001) but the difference in anti-sickness medicine use (30.77% vs 52.38%) was not significant.
Effect sizes as reported
Korea and Japan give no usable effect figures in the abstract; Turkey P < .001.
Why this rating
Small trials with a smell people can notice, a no-aroma or saline comparison, one non-randomised design, and a blend in the Japanese trial that cannot be credited to ginger.
Form and dose studied
Not covered. This page gives no amounts and no ways of using the oil.
Who was studied
Adults after surgery, in hospital.
Limits
No placebo that smells the same; short follow-up; effect sizes missing; the Japanese result is for a three-oil blend.
Why researchers looked
Ginger root is a well-known folk remedy for nausea, so the oil was tried as a scent.
Traditional use
Ginger root has long been used for nausea in many food and medical traditions. The oil is a different product from the root.
Proposed mechanism Hypothesis
How a scent could affect nausea is not known. Smell, expectation and distraction may all play a part.
A proposed mechanism does not show that the effect happens in people.
Strong scent can bother some people, including people with asthma. Never swallow the oil. See the Safety tab.
Nausea after breast implant surgery (ginger oil on the airway tube)
Very low certaintyIn a small UK trial of 30 women, ginger oil placed on the airway tube was linked with a lower nausea score than a placebo oil. The abstract has unexplained numbers, one author has a tie to a breast-implant company, and this route is only used by anaesthetists in an operating room.
1 studiesNot covered. This page gives no amounts and no ways of using the oil.
Studies, doses and limits
What the trials found
Double-blind, placebo-controlled trial, 30 women having breast implant surgery; three drops of ginger oil or placebo oil on the laryngeal mask.
Results
Mean nausea and vomiting score 1.70 with ginger oil versus 4.20 with placebo (p < .001). Pain score 5.0 versus 5.9. The authors say it also reduced opioid use.
Effect sizes as reported
Nausea score 1.70 vs 4.20.
Why this rating
One small single-centre trial; the analysis refers to about 20 people although 30 were randomised, with no explanation; a conflict of interest is declared with a breast-implant company.
Form and dose studied
Not covered. This page gives no amounts and no ways of using the oil.
Who was studied
Women having breast implant surgery.
Limits
Route is not the same as scent or skin use; do not copy it at home.
Why researchers looked
Nausea is common after anaesthesia, and the oil was tried in theatre.
Traditional use
No traditional use of this kind.
Proposed mechanism Hypothesis
Not known.
A proposed mechanism does not show that the effect happens in people.
Strong scent can bother some people, including people with asthma. Never swallow the oil. See the Safety tab.
Chemotherapy nausea and vomiting (ginger oil inhaled from a necklace)
Mixed findingsA Malaysian cross-over trial in 60 women with breast cancer found ginger oil scent eased nausea only briefly. It did not change vomiting, and the overall effect on nausea was not significant. Some quality-of-life scores improved. The authors themselves call the evidence not convincing.
1 studiesNot covered. This page gives no amounts and no ways of using the oil.
Studies, doses and limits
What the trials found
Single-blind randomised cross-over trial; 60 women finished; ginger oil versus a ginger-smelling fragrance oil on a necklace for 5 days each.
Results
Nausea score lower in the first phase (P=0.040) but the overall treatment effect was not significant (P=0.183). Vomiting: no effect (P=0.594). Global health status improved (P<0.001), with about 10 points better on role functioning and appetite loss.
Effect sizes as reported
Mixed: P=0.040 early, P=0.183 overall.
Why this rating
One trial with a fragrance placebo; the authors judge the nausea evidence not sufficiently convincing; quality-of-life gains are secondary results.
Form and dose studied
Not covered. This page gives no amounts and no ways of using the oil.
Who was studied
Women with breast cancer on chemotherapy (most on highly emetogenic regimens).
Limits
Single trial, short, women only.
Why researchers looked
Chemotherapy nausea is hard to control, so scent is sometimes tried as an add-on.
Traditional use
Ginger root is traditionally used for nausea.
Proposed mechanism Hypothesis
Not known.
A proposed mechanism does not show that the effect happens in people.
People on chemotherapy should ask their cancer team before using any scented product; some are bothered by smells.
Aromatherapy in general for nausea after surgery (not specific to ginger)
Low certaintyA 2026 pooled analysis of 13 trials (1,294 patients) found less nausea, fewer people needing rescue anti-sickness medicine and less overall nausea and vomiting with aromatherapy. The summary does not say which oils were used, so it cannot show that ginger oil works.
1 studiesNot covered. This page gives no amounts and no ways of using the oil.
Studies, doses and limits
What the trials found
Systematic review and meta-analysis of 13 randomised trials, searches to October 2025.
Results
Nausea score lower (mean difference -1.02, 95% CI -1.60 to -0.45); rescue anti-sickness medicine OR 0.33 (95% CI 0.20 to 0.55); composite PONV OR 0.24 (95% CI 0.12 to 0.50). No serious adverse events were reported but safety was not systematically assessed.
Effect sizes as reported
See results.
Why this rating
Pooled trials are small and hard to blind because the smell is obvious; the abstract does not name the oils and gives no certainty grade.
Form and dose studied
Not covered. This page gives no amounts and no ways of using the oil.
Who was studied
Patients after surgery.
Limits
Not specific to ginger; abstract only was read.
Why researchers looked
To see whether the small ginger oil trials fit a wider pattern.
Traditional use
Not applicable.
Proposed mechanism Hypothesis
Not known.
A proposed mechanism does not show that the effect happens in people.
Strong scent can bother some people, including people with asthma. Never swallow the oil. See the Safety tab.
Knee pain and knee osteoarthritis (massage with ginger oil)
Low certaintyTwo small trials tested massage with ginger oil on painful knees. In Hong Kong a ginger and orange oil massage helped more than olive oil massage or no massage after 1 week, but the benefit was gone at 4 weeks. In Turkey, people with knee osteoarthritis who rubbed in ginger oil twice a week had less pain than those on standard treatment alone. Massage itself soothes, so the oil's own part is unclear.
3 studiesNot covered. This page gives no amounts and no ways of using the oil.
Studies, doses and limits
What the trials found
Hong Kong 2008: 59 older adults, 6 massages of a ginger and orange oil blend over 3 weeks versus olive oil massage versus no massage (double-blind placebo design). Turkey 2017: 68 adults with knee osteoarthritis, ginger oil self-massage twice a week plus standard treatment versus standard treatment only.
Results
Hong Kong: between-group differences at 4 weeks not significant (pain p=0.48, stiffness p=0.14, function p=0.45); at 1 week pain and function better with the oil blend than both other groups (both p=0.03). Turkey: lower pain (VAS) at weeks 1 and 5 and lower WOMAC total and function scores (p<.05).
Effect sizes as reported
Hong Kong p=0.03 at 1 week only; Turkey p<.05; no figures in the abstracts.
Why this rating
Small, short trials. One is a two-oil blend and benefit faded. The other compared oil massage with no massage, so rubbing itself cannot be separated from the oil.
Form and dose studied
Not covered. This page gives no amounts and no ways of using the oil.
Who was studied
Older adults with knee pain; adults with knee osteoarthritis.
Limits
No long-term follow-up; no trial of ginger oil alone against plain-oil massage with strong numbers.
Why researchers looked
Ginger root is a traditional remedy for sore joints.
Traditional use
Ginger root and warming rubs are used for joint pain in many traditions.
Proposed mechanism Preliminary mechanism
Ginger compounds block inflammation signals in lab tests; this has not been shown for the oil on a human knee.
A proposed mechanism does not show that the effect happens in people.
Used on skin only after dilution in a carrier oil; essential oils can cause rashes and allergy. See the Safety tab.
Chronic low back pain (Swedish massage with ginger oil)
Low certaintyA Thai trial of 140 older adults found Swedish massage with ginger oil eased long-lasting back pain and disability slightly more than traditional Thai massage. Both helped. There was no group getting plain massage without ginger, so the oil's part is unknown.
2 studiesNot covered. This page gives no amounts and no ways of using the oil.
Studies, doses and limits
What the trials found
Randomised trial, 140 older adults in Thailand; 30-minute sessions twice a week for 5 weeks; Swedish massage with aromatic ginger oil versus traditional Thai massage; follow-up to 15 weeks. A 2020 narrative review mentions this trial.
Results
Both groups improved on pain and disability. Ginger oil massage was better than Thai massage for pain (p=0.04) and for disability at short and long term (p=0.04).
Effect sizes as reported
p=0.04.
Why this rating
One trial, different massage styles being compared, modest p values, no plain-massage comparison.
Form and dose studied
Not covered. This page gives no amounts and no ways of using the oil.
Who was studied
Older adults with chronic low back pain.
Limits
The comparison was a different kind of massage, not the same massage without ginger.
Why researchers looked
Back pain is common and massage oils are widely used.
Traditional use
Ginger rubs are used for aches in traditional medicine.
Proposed mechanism Hypothesis
Not known for the oil.
A proposed mechanism does not show that the effect happens in people.
Used on skin only after dilution in a carrier oil; essential oils can cause rashes and allergy. See the Safety tab.
Constipation in older adults (abdominal massage with ginger and lavender oil)
Not enough evidenceA small Turkish trial of 40 nursing-home residents found stools were softer and constipation scores better after four weeks of abdominal massage with a ginger and lavender oil blend than with no treatment. It cannot say what the oils added to the massage.
1 studiesNot covered. This page gives no amounts and no ways of using the oil.
Studies, doses and limits
What the trials found
Randomised trial, 40 older nursing-home residents; 15 minutes of massage on weekdays for 4 weeks versus no intervention.
Results
At weeks 2 and 4 Bristol Stool Chart scores rose and Constipation Severity Scale scores fell more in the massage group (p<0.05); not different at the first follow-up.
Effect sizes as reported
p<0.05.
Why this rating
40 people, a two-oil blend, and a no-massage control, so ginger oil cannot be singled out.
Form and dose studied
Not covered. This page gives no amounts and no ways of using the oil.
Who was studied
Older adults in a nursing home with constipation.
Limits
One small trial.
Why researchers looked
Abdominal massage is used for constipation; the oils were added to it.
Traditional use
Not applicable.
Proposed mechanism Hypothesis
Not known.
A proposed mechanism does not show that the effect happens in people.
Used on skin only after dilution in a carrier oil; essential oils can cause rashes and allergy. See the Safety tab.
Menopause symptoms (ginger oil aromatherapy)
Not enough evidenceOne Indonesian trial reports less menopausal symptoms after 4 weeks of 20 minutes a day of ginger oil, lemongrass oil or both. The summary has numbers that do not add up (355 women but three groups of 89) and no comparison with no oil. It cannot be relied on.
1 studiesNot covered. This page gives no amounts and no ways of using the oil.
Studies, doses and limits
What the trials found
Randomised trial at a public health centre in Indonesia: ginger oil, lemongrass oil, or both, 20 minutes a day for 4 weeks.
Results
All three groups improved on a symptom scale. No effect sizes are given.
Effect sizes as reported
No figures in the abstract.
Why this rating
No clear no-oil comparison, unexplained numbers, one trial.
Form and dose studied
Not covered. This page gives no amounts and no ways of using the oil.
Who was studied
Menopausal women.
Limits
Cannot be judged from the abstract.
Why researchers looked
Scent is a popular add-on for menopause symptoms.
Traditional use
Not applicable.
Proposed mechanism Hypothesis
Not known.
A proposed mechanism does not show that the effect happens in people.
Strong scent can bother some people, including people with asthma. Never swallow the oil. See the Safety tab.
Inflammation, germs and antioxidant effects (lab and animal work only)
Very low certaintyIn test tubes and on mouse ears, ginger oil slowed some bacteria, scavenged free radicals and lowered swelling signals. None of this has been shown in people, and mouse skin or a test tube is a very different place from a human body.
2 studiesNot covered. This page gives no amounts and no ways of using the oil.
Studies, doses and limits
What the trials found
Lab and animal studies only: antioxidant tests on one Ecuador oil and in yeast cells; mouse ear swelling, bacteria and cell line tests on another oil.
Results
On mouse ears the oil lowered swelling and COX-2, IL-6 and NF-kB markers, at high concentrations better than ibuprofen. It also showed some antibacterial and antioxidant effect in the lab.
Effect sizes as reported
Lab and mouse only.
Why this rating
Not tested in people; one oil sample per study; high concentrations.
Form and dose studied
Not covered. This page gives no amounts and no ways of using the oil.
Who was studied
None; not a human result.
Limits
Animals and test tubes do not predict what happens in people.
Why researchers looked
Lab work is where most ginger oil research sits.
Traditional use
Not applicable.
Proposed mechanism Preliminary mechanism
Zingiberene and related compounds are suspected, but this is lab-level only.
A proposed mechanism does not show that the effect happens in people.
None; this is not a use.

Evidence at a glance: what changed in 3 lab markers
Tap a number to show only those markers. Counts are markers, not people.
The evidence
The research centre for Ginger Oil. Every record here was checked against PubMed or the publisher's page; we never list a study we have not verified.
Evidence by outcome
Bars show how many studies we found for each outcome, not how well it works. People are added up across trials only (reviews are not added, to avoid double counting).
How we rate evidence
High certainty
Several well-run trials or reviews agree; further research is unlikely to change the picture much.
Moderate certainty
Good trials point the same way, but some doubt remains.
Low certainty
Small, short or inconsistent trials. The finding could change with better research.
Very low certainty
Very little or very weak human data. Treat as a possibility only.
Mixed findings
Trials or reviews disagree with each other.
Not enough evidence
Not enough human research to say either way.
Evidence against
Good research found no benefit, or found harm.
We take the reviewers' own risk-of-bias and GRADE statements where they exist, and otherwise judge from study size, design, consistency, directness and whether a product matches what is sold. Many publications do not make evidence high. Method note: We read the abstracts of 16 PubMed papers and the Poison Control, Pet Poison Helpline, FDA and EMA pages, checked the plant name in GBIF and a compound in PubChem. We could not read the Tisserand Institute, LiverTox or LactMed.

Main points to know 5
- Never swallow ginger oil, and keep it away from children and pets.. Poison Control says some essential oils are poisonous if swallowed or absorbed through the skin, and that breathing an oil into the lungs while choking or swallowing can cause pneumonia. Children have thin skin and immature livers and may be more sensitive. We found no poisoning report for ginger oil itself in the sources read, and that is not proof that it is safe. If anyone swallows an essential oil, call poison control (US: 1-800-222-1222) or your emergency number. Authoritative guidance 18
- Use on skin only after dilution in a carrier oil; skin allergy is a real possibility.. Poison Control says diluting an essential oil in a carrier oil is the best way to avoid a bad skin reaction, that rash is the most common allergic reaction, and that oils should not go on damaged skin. A large German patch-test series found 8.3% of dermatitis patients reacted to at least one of twelve essential oils; the abstract names six oils above 1%, and ginger oil is not among them, but it does not name the other six. No patch-test rate for ginger oil was found. Authoritative guidance and observational 18 2
- Cats and birds are at greatest risk from essential oils; keep ginger oil away from pets.. Pet Poison Helpline says essential oils can affect all species, with cats and birds at greatest risk. Signs include drooling, vomiting, lethargy, loss of appetite and irritation of the airways, skin or mouth. Its page does not mention ginger, and that is not proof that ginger oil is safe for pets. Do not make a pet vomit; call a vet or a pet poison line. Authoritative guidance 19
- Scent can bother people with asthma and strong smells can trigger symptoms.. Poison Control and the FDA do not give ginger-specific breathing warnings. We found no trial that tested ginger oil in people with asthma, so no safety claim is made either way. If a smell makes you cough, wheeze or feel unwell, stop and get fresh air. Absence of data 18 17
- Ginger oil is not the same as ginger root, tea or capsules.. The European medicines assessment for ginger covers the powdered dried root or a tincture taken by mouth, and does not mention the essential oil. Its cautions (not in pregnancy or breastfeeding; not for children) are about those products and cannot be carried over to the oil, in either direction. Regulatory 20
Side effects 5
| Effect | How often | Severity and recovery | Evidence |
|---|---|---|---|
| Skin rash or allergic contact dermatitis Poison Control calls rash the most common allergic reaction to essential oils. No ginger-oil patch-test rate was found. | Not established | mild to moderate; can be severe Usually settles after stopping and washing the oil off | Authoritative guidance 18 2 |
| Poisoning if swallowed (stomach upset, drowsiness and worse in children) General essential-oil guidance. No ginger oil poisoning case was found in the sources read. | Not established | potentially serious Not described for ginger oil | Authoritative guidance 18 |
| Breathing the oil into the lungs (aspiration pneumonia) Applies if oil is swallowed and the person chokes or coughs. | Not established | serious Needs medical care | Authoritative guidance 18 |
| Adverse events in the aromatherapy trials One trial reported no adverse events; the meta-analysis says no serious events were reported but safety was not systematically assessed. Small trials cannot rule out rare problems. | Not established | none reported n/a | Controlled trial 4 13 |
| Pet poisoning from essential oils generally (drooling, vomiting, lethargy, breathing or skin irritation) Ginger is not named on the helpline page. | Not established | mild to severe Mild cases settle in hours; severe cases can take 3 to 7 days | Authoritative guidance 19 |
Liver
No report of liver injury in people from ginger essential oil was found in the sources read, and LiverTox was not searched. In a 13-week rat study of swallowed ginger oil, blood liver tests and liver tissue showed no treatment-related change at the doses tested; the authors call it preliminary. 5
How often. Not known in people.

| Situation | Advice | Evidence |
|---|---|---|
| Known allergy to ginger or to essential oils | Do not use. A past rash to a strong-smelling product is a reason to stop. | Authoritative guidance 18 |
| Swallowing the oil | Do not swallow essential oil. It can be poisonous. | Authoritative guidance 18 |
| Damaged or broken skin | Poison Control says not to put essential oils on damaged skin. | Authoritative guidance 18 |
| Babies and young children | Keep the oil away from them and out of reach. Children may be more sensitive than adults. | Authoritative guidance 18 |
| Homes with cats or birds | Cats and birds are at greatest risk from essential oils; ask a vet before any use around them. | Authoritative guidance 19 |
Overdose, product quality and regulators
Summary. There are few safety data for ginger oil in people. The main data are a preliminary 13-week rat study and general essential-oil guidance. The rat study found no harm at the doses tested; it does not make swallowing safe for people, children or pets.
Animal. A 13-week study in Wistar rats found no deaths and no treatment-related changes in blood tests, liver, kidney or organ tissue. Zingiberene was detected in blood after dosing.
Human doses studied. The trials used the oil as a scent, on an airway tube, or diluted in massage oil. No amounts are given here.
High dose or long term signals. None reported in the sources read.
Overdose response. Call poison control or your emergency number if anyone swallows essential oil.
Genotoxicity. Not read.
Toxic or hazardous parts. Not applicable; the oil is the concentrated product.
Quality varies between essential oil bottles, and the makeup of ginger oil differs between samples.
Different makeup between samples. Two lab papers gave different main compounds: one Ecuador sample had zingiberene 17.4%, geranial 10.5% and neral 9.1%; another oil had zingiberene 19.71%, beta-cedrene 12.85% and farnesene 12.17%. The rat study oil had zingiberene at 31.08%. 3 16 5
Not the same as infused ginger oil. Some bottles sold as ginger oil are plant oil that ginger has soaked in. That is a different product from the essential oil and was not what the trials tested.
Unknown species, strength or contaminants. The FDA says natural does not mean safe, and cosmetics must still meet safety requirements; claims to treat or relieve conditions make a product a drug. 17

When to get medical help
- If a child or pet may have swallowed ginger oil (or any essential oil), call poison control straight away (US: 1-800-222-1222; for pets a vet or a pet poison line) or your emergency number. Do not make them vomit.
- Coughing or choking while swallowing oil, followed by fever or trouble breathing: get medical help.
- Hives, swelling of the face or lips, or trouble breathing after any essential oil: emergency help.
- A spreading rash, blistering or burning on the skin: stop, wash the area with soap and water, and get medical help if it does not settle.
- Drowsiness, vomiting or unsteadiness in a child or pet after exposure to an essential oil: seek help.
Stop using the product and contact a clinician or emergency service. In the US, Poison Control is 1-800-222-1222.

Frequently asked questions
Is ginger oil safe to swallow?
No. We do not advise swallowing it. Poison Control says some essential oils are poisonous if swallowed, and choking on an oil can cause pneumonia. We found no poisoning report for ginger oil, which is not proof of safety. If anyone swallows it, call poison control (US: 1-800-222-1222) or your emergency number.
Does ginger oil help nausea?
Possibly, as a scent. Three small trials after surgery found less nausea, and a 2026 meta-analysis of 13 aromatherapy trials found lower nausea scores. The trials are small and easy to unblind, one used a three-oil blend, and in chemotherapy the effect was brief and not significant overall.
Can ginger oil cause an allergic reaction?
Is ginger oil safe for cats and dogs?
Not as a strong oil. Pet Poison Helpline says essential oils can affect all species, with cats and birds at greatest risk, and ginger is not named. Signs include drooling, vomiting and lethargy. Do not make a pet vomit; call a vet or pet poison line.
Is ginger oil safe in pregnancy or breastfeeding?
Not known. We found no study of the oil. The European Medicines Agency advises against ginger root medicines in pregnancy and breastfeeding, but that is about the root and cannot be moved to the oil. Ask a midwife, doctor or pharmacist.
Is ginger oil safe for children?
Keep it out of reach. Poison Control says children have thin skin and immature livers and may be more sensitive. No trial tested the oil in children. Do not use near the faces of babies and young children.
Does ginger oil help knee pain or back pain?
Maybe a little for a while, in massage. In Hong Kong a ginger and orange oil massage helped at 1 week but not at 4. A Turkish trial found less pain with ginger oil self-massage plus standard care. A Thai trial found ginger oil massage beat traditional Thai massage. None of these separates the oil from the massage itself.
Is ginger oil the same as ginger root, tea or capsules?
Is ginger oil sun-sensitising (phototoxic)?
The FDA says some citrus oils can harm skin exposed to sun. The sources we read do not say ginger oil is phototoxic, but we could not read an oil-specific source either, so this is not confirmed.
Does ginger oil interact with medicines?
Poison Control says essential oils may interact with medicines. We found no study of ginger oil and medicines, which is not proof of no interaction. Ask a pharmacist, especially before surgery or if you take blood thinners.
Does ginger oil help with menopause symptoms or constipation?
