Essential Oils for Pain and Muscle Aches: What the Research Shows
What trials and reviews found for essential oils and pain: period cramps, muscle and joint aches, and after surgery, with the limits of the studies and the safety points.
Content last updated . This page has not been medically reviewed.
Safety first. Natural products can cause side effects and interact with medicines. Read essential oil safety before you use anything on this page.
Safety first. Do not swallow essential oils. If anyone has swallowed one, call Poison Help at 1-800-222-1222; call 911 for collapse, a seizure or trouble breathing. Poison Control says even a small amount of camphor is dangerous if swallowed, and that swallowing wintergreen oil is roughly like swallowing a large number of adult aspirin tablets. [1] Pain that is severe, sudden, getting worse or not explained needs a clinician, not an oil.
What the research shows
Evidence labels follow our library standard. "Human trials" means trials in people; the form studied matters, because inhaled scent, massage and skin products are different things.| Question | What the source found | Strength of evidence | Form and population studied |
|---|---|---|---|
| Period cramps (primary dysmenorrhea) | A 2018 systematic review of placebo-controlled trials reported lower pain than placebo and called its evidence moderate, but with high heterogeneity (results varied a lot between trials). [3] A second 2018 meta-analysis said the methods were diverse, the basis weak and the chance of bias high. [4] | Promising but limited | Inhaled scent, aromatherapy massage and, in some trials, oral products; women with menstrual pain |
| Muscle and joint (musculoskeletal) pain | A 2023 meta-analysis of eight randomized trials found topical essential oils were beneficial as an add-on, reducing pain and stiffness; the biggest effect was immediately after treatment. [5] | Promising but limited | Oils applied to the skin, often with massage; adults with musculoskeletal conditions |
| Pain after surgery | A 2025 review of 15 trials found inhaled lavender significantly reduced postoperative pain, but the evidence was insufficient to say it reduces pain medicine use. [6] | Promising but limited | Lavender scent (Lavandula angustifolia and related species as labeled in each trial); adults after surgery |
| Arthritis | Proper evidence not found. We searched PubMed for randomized trials of essential oils for arthritis and found none specific to it that we could read. NCCIH says aromatherapy is sometimes added to massage for conditions such as knee pain from osteoarthritis, which describes use, not results. [7] | Insufficient evidence | Not applicable |
| General pain (stress study) | In one NCCIH-described study, lemon and lavender scents did not change stress indicators, immune markers or pain control. [7] | Mixed | Inhaled scent; people under stress |
What these results do not tell us
- Some period-pain trials in the 2018 review tested oral aromatherapy products. Those are trial products, and we do not suggest swallowing any essential oil. [3]
- A trial of "aromatherapy massage" cannot show that the oil did the work unless it also compares against massage without the oil. See Aromatherapy massage: what the research shows and Essential oils in sports rubs and muscle products.
- We read abstracts of these reviews. Oil types, amounts and dilutions differ between trials and are not a guide for readers.
Toothache
Proper evidence not found. We looked for a source we could read supporting an essential oil for toothache and did not find one. The NHS says to see a dentist if toothache lasts more than two days, because a dentist can treat the cause. [8] Do not put oils in the mouth; see Swallowing essential oils: what poison centers say.Frequently asked questions
Do essential oils relieve period cramps?
Two 2018 reviews of small trials reported lower pain scores with aromatherapy than with placebo, but both noted weaknesses such as varied methods and high heterogeneity. [3] [4] Treat this as promising but limited. See also Essential oils for menopause and period symptoms.
Do essential oils help muscle aches?
A 2023 meta-analysis of eight trials found topical essential oils helped as an add-on for pain and stiffness in musculoskeletal conditions. [5] It does not show that any single oil works, or that oils beat standard care.
Do essential oils help arthritis?
Proper evidence not found in the sources we read. We searched PubMed for essential oil trials in arthritis.
Can I use an essential oil for toothache?
We found no source supporting it. The NHS advises seeing a dentist if toothache lasts more than two days. [8] Do not swallow essential oils; call Poison Help at 1-800-222-1222 if one is swallowed. [1]
Is lavender scent proven for pain?
A 2025 review found inhaled lavender significantly reduced pain after surgery in adults, but called the evidence insufficient on pain medicine use. [6] See Lavender oil for the wider picture.

Safety for skin and body
- Skin reactions and allergy: Poison Control says many essential oils can cause rashes, allergy is a real possibility, and oils should not be used on damaged skin. [1] Stop a product that causes a rash and wash it off. [1] See Patch testing and what to do after a skin reaction.
- Warming rubs: Poison Control says wintergreen oil, used in some pain skin products, is very dangerous if more than a tiny amount is swallowed, and that camphor poisoning has occurred when camphor skin preparations were used on children more often than the label said. [1] Keep these products away from children; see Camphor oil: why it can be dangerous.
- Medicines: Poison Control says essential oils may interact with medications. [1] Ask a pharmacist if you take regular medicines; see How interactions work.
- Pregnancy, breastfeeding, babies and children: we did not find pain-specific advice we could verify. Poison Control says children have thin skin and immature livers, which might make them more susceptible to toxic effects than adults. [1] Ask a clinician first; see Essential oils around babies and children.
- Ask a clinician about pain that is severe, sudden, getting worse or unexplained.
