As your due date approaches, it is natural to want tools that help you feel calmer and more in control. Aromatherapy for labor is one of the gentlest options available, and it is genuinely popular with women and midwives alike — but the evidence behind it is more mixed than most articles admit, and knowing where it is strong and where it is thin will help you use it well.
What Aromatherapy for Labor Actually Involves
Aromatherapy uses concentrated essential oils extracted from plants to support physical and emotional wellbeing. During labor, it is used to ease anxiety, soften the perception of pain, and make the room feel like yours rather than a clinical space.
It works through two routes: inhalation, where scent molecules reach the olfactory system and the limbic areas of the brain involved in emotion, and topical application, where diluted oils are absorbed through the skin during massage. Neither replaces medical pain relief. Both sit alongside the other comfort measures you may already be practicing, such as mindful breathing during pregnancy.
What the Evidence Says About Labor Pain
Start with the most rigorous assessment, because it is the one usually left out. A Cochrane review of aromatherapy for pain management in labor found only two trials meeting its inclusion criteria, covering 535 women. Those trials were judged at low risk of bias, and they found no difference between aromatherapy and control groups in pain intensity, assisted vaginal birth, or caesarean section. The authors concluded that there is a lack of studies in this area and that further research is needed before recommendations can be made for clinical practice[1].
Later reviews that cast a wider net reach warmer conclusions. A 2020 systematic review found that most of the trials it analyzed indicated a positive effect of aromatherapy on labor pain and anxiety, while explicitly noting that evidence quality varied across studies[2]. A 2021 systematic review and meta-analysis reported that aromatherapy may decrease both anxiety and pain during the first stage of labor in women giving birth for the first time[3]. A broader 2024 review of complementary therapies across pregnancy, birth and the postpartum period reached similarly cautious-but-positive conclusions[4].
Why the disagreement? Largely because the two groups are reading different evidence. Cochrane applied strict inclusion criteria and found almost nothing that met them. The later reviews included many more trials, most of them small, single-center, and conducted in a handful of countries. Aromatherapy is also close to impossible to blind — you know whether the room smells of lavender — so expectation effects are difficult to separate from the oil itself. None of that makes the positive findings worthless. It does mean they rest on weaker foundations than a confident headline suggests.
A fair summary: aromatherapy in labor appears safe when used sensibly, many women report that it helps them feel calmer, and the evidence that it reduces measured pain scores is suggestive rather than settled. That is a reasonable basis for trying it as a comfort measure. It is not a basis for planning your pain relief around it.
Lavender: The Most Studied Oil for Labor
If you only take one oil to your birth, lavender (Lavandula angustifolia) is the one with the most direct evidence behind it. In a randomized controlled trial of 121 first-time mothers, women given lavender by inhalation or by massage reported milder labor pain than the control group. The trial also found a pattern worth knowing: inhalation worked best in the early phase, while massage with lavender oil was more effective during the active and transition phases[5].
An earlier placebo-controlled trial of 120 first-time mothers, using distilled water as the control, found lavender inhalation at 4–5, 6–7 and 8–9 centimeters of dilation was associated with a significant reduction in pain scores. Notably, it found no difference in the length of the active phase or the second stage of labor[6]. That second finding matters as much as the first: lavender may change how labor feels without changing how long it takes.
Both trials were modest in size and neither was blinded in any meaningful sense. Read them as encouraging rather than conclusive — but among the oils used in labor, lavender is where the evidence is least thin, and it is well tolerated by most people.
Other Oils Used During Labor
Beyond lavender, a few oils appear regularly in both midwifery practice and the research literature. The table below summarizes when each is typically used and what the evidence looks like.
| Oil | Typically used for | Evidence | Pregnancy safety |
|---|---|---|---|
| Lavender | Anxiety, pain perception | Two small RCTs specific to labor | Generally considered safe in labor |
| Clary sage | Active labor only | Little direct trial evidence | Avoid during pregnancy |
| Sweet orange | Nausea, anxiety | One 2025 clinical trial | Generally well tolerated |
| Damask rose | Pain, emotional support | One trial in first-time mothers | Avoid during pregnancy |
Clary Sage (Salvia sclarea)
Clary sage should be reserved for active labor and avoided during pregnancy. It is often described as supporting contractions that have already started, and some midwives suggest it where contractions are slow or irregular. Be clear about what it does not do: clary sage does not induce labor, and it should never be used to try to bring labor on. Direct trial evidence for it in labor is limited, so its reputation rests more on practice than on published data.
Sweet Orange (Citrus sinensis)
A 2025 clinical trial suggested sweet orange oil may help with both pain and anxiety during labor[7]. Its light citrus scent is often easier to tolerate than heavier florals, and it may help with the nausea that many women experience in labor. It is a reasonable choice if strong scents make you queasy.
Damask Rose (Rosa damascena)
A trial in first-time mothers suggested damask rose essential oil may reduce pain and anxiety during the first stage of labor[8]. Its floral scent is strongly associated with comfort and care for many people, which may be part of the effect. Like clary sage, rose is reserved for labor rather than pregnancy.
Does Aromatherapy Help With Contractions?
This is one of the most common questions, and the honest answer is narrower than the internet suggests. No essential oil has been shown to start labor, and none should be used with that intention. The 2016 lavender trial that measured it found no difference in the duration of the active phase or the second stage[6], which is the clearest available answer: aromatherapy did not speed labor up.
What aromatherapy may plausibly do is change how you experience contractions — lowering anxiety between them, giving you something steady to focus on during them, and making the gaps feel more restful. That is a worthwhile goal in itself. If your contractions have stalled, or you have concerns about progress, that is a conversation with your midwife or doctor, not something to manage with oils.
How to Use Aromatherapy During Labor
- Inhalation: Add 2–3 drops to a cotton ball, tissue, or diffuser and keep it near you. This is the most practical option in hospital, where diffusers are often not permitted.
- Massage: Dilute in a carrier oil such as sweet almond or coconut at 1–2% — roughly 2–4 drops per teaspoon. A birth partner can work on the lower back, shoulders or feet. Pairing this with breathing techniques for stress relief tends to work better than either alone.
- Compress: Add a few drops to a bowl of warm or cool water, soak a flannel, and apply to the forehead, lower back or abdomen.
- Bath: If you are using water in early labor, add 4–6 drops mixed into a tablespoon of carrier oil or full-fat milk so the oil disperses. Never add undiluted essential oils to bath water.
Planning Aromatherapy Into Your Birth Preferences
- Raise it with your midwife or doctor during pregnancy, and ask your unit about its policy — many hospitals restrict scented products in shared spaces, and some require oils to be supplied or approved by staff.
- Choose two or three oils rather than a collection. Sensory overload is real, and fewer options are easier to manage when you are concentrating on something else.
- Test each one after 37 weeks to check for skin reactions and to find scents you genuinely like.
- Pack them with a carrier oil, cotton balls and any diffuser you have been told is allowed.
- Brief your birth partner, and accept in advance that your preferences may change completely once labor starts. That is normal.
Safety and When to Avoid Essential Oils
A critical review of aromatherapy in obstetrics concluded it can be administered safely across the perinatal period when proper guidelines are followed[9]. Those guidelines matter:
- Consult your midwife or doctor before using essential oils in pregnancy or labor.
- Buy from a supplier that publishes the botanical name, country of origin and batch information. "Therapeutic grade" is a marketing phrase, not a regulated standard.
- Never ingest essential oils during pregnancy or labor.
- Avoid clary sage, jasmine and rose during pregnancy — reserve them for active labor.
- Keep oils away from your newborn until you have checked with a healthcare professional.
- Seek professional guidance first if you have asthma, epilepsy, or another medical condition.
- Patch test before any topical use, and stop immediately if skin reacts.
Understanding how your body responds to stress can help you notice the moments in labor when a calming measure is most likely to help.
For Birth Partners
- Learn the oils before the day, so you are not reading labels during a contraction.
- Pre-dilute massage oil into a small container in advance.
- Watch for cues. If scent becomes unwelcome, remove it from the room immediately rather than asking twice.
- Offer a choice — "lavender or orange?" — rather than deciding for her.
- Less is more. A faint scent is usually more tolerable than a strong one, especially with nausea.

A Realistic Place for Aromatherapy in Your Birth
Aromatherapy is a comfort measure with a modest and uncertain evidence base, a good safety record when used properly, and a lot of anecdotal warmth behind it. Held that way, it is genuinely useful: something familiar and pleasant in an unfamiliar room, and one more thing you get to decide.
Try your chosen oils during late pregnancy, so the scents are already associated with calm by the time you need them. Keep your expectations proportionate to the evidence, keep your pain relief options open, and treat the oils as one tool among several rather than the plan itself.
Your body knows how to give birth. Aromatherapy, at its best, simply helps the room around you feel like somewhere you can do it.

Frequently Asked Questions
Does aromatherapy help with labor pain?
The evidence is mixed. A Cochrane review of two low-risk-of-bias trials in 535 women found no difference in pain intensity, while wider reviews of many smaller trials report reductions in pain and anxiety. It is reasonable to try as a comfort measure, but not as your pain relief plan.
Which essential oil is best for labor?
Lavender has the most direct evidence, with two randomized trials in first-time mothers. Sweet orange is a good alternative if strong scents make you queasy, and damask rose has one supporting trial.
Is lavender oil safe to use during labor?
Lavender is generally considered safe in labor and is well tolerated by most people. Dilute it to 1 to 2 percent for massage, never take it by mouth, and check with your midwife or doctor first.
Can essential oils bring on contractions?
No essential oil has been shown to start labor, and none should be used with that intention. Clary sage is sometimes used once active labor has already begun, but it does not induce labor. A trial that measured it found aromatherapy did not shorten labor.
Which essential oils should I avoid in pregnancy?
Clary sage, jasmine and rose are reserved for active labor rather than pregnancy. Never ingest essential oils, patch test before any skin use, and seek professional guidance first if you have asthma, epilepsy or another medical condition.
