Several essential oils have clinical evidence supporting their use during labor, primarily for reducing pain and anxiety. Lavender is the most widely studied, but clary sage, rose, geranium, chamomile, and peppermint have all shown benefits in trials involving laboring women. None of these replace medical pain management, but they can be a useful complementary tool, especially during early labor.
Lavender: The Strongest Evidence
Lavender is the most researched essential oil for childbirth, and the results are consistently positive. In a 2023 randomized controlled trial of 100 women, those who inhaled lavender oil reported pain scores roughly 40% lower at rest and about 33% lower after movement compared to a placebo group. Anxiety scores also dropped significantly.
Multiple studies have tested lavender through different methods: inhalation, massage, acupressure, footbaths, and compression. Across these approaches, anxiety levels typically decreased within 60 minutes of exposure, and in some cases the effect was nearly instant. Lavender appears most effective during the first stage of labor, when contractions are building but the cervix is still dilating.
Clary Sage for Encouraging Contractions
Clary sage is commonly recommended by midwives for its potential to stimulate uterine activity. The proposed mechanism involves triggering the release of oxytocin, the hormone responsible for contractions. In one study, women who used a footbath with clary sage and lavender oils showed a significant increase in salivary oxytocin levels afterward. No adverse events were recorded in any participant, and no babies showed abnormal heart rates or required intensive care.
That said, the increase in oxytocin didn’t always translate into stronger subjective contractions in that particular study. The effect may be mild or may work better in combination with other labor stimulation. Because clary sage has a theoretical ability to promote contractions, most practitioners advise avoiding it before you’re at full term.
Rose, Geranium, Chamomile, and Peppermint
Beyond lavender and clary sage, several other oils have shown measurable benefits during labor:
- Rose: Inhaling rose oil reduced labor anxiety in multiple trials, though results were mixed, with some studies finding no significant effect. Rose footbaths also performed well.
- Geranium: Inhaled geranium oil reduced anxiety within 20 minutes in clinical testing. When compared head-to-head with orange peel oil, geranium produced a greater anxiety reduction.
- Chamomile: Shown to reduce both pain intensity and anxiety levels during the first stage of labor, particularly in first-time mothers.
- Peppermint: Two separate studies confirmed its effectiveness for both labor pain and anxiety. Some women also find it helpful for nausea during labor, though the evidence for that specific use is more anecdotal.
How to Use Them During Labor
The most common and practical methods are inhalation and massage. For inhalation, you can place a few drops on a cotton ball or personal inhaler stick and breathe it in during contractions. This gives you control over how much you’re exposed to and lets you stop if the scent becomes overwhelming, which happens often as labor intensifies.
For massage, essential oils need to be diluted in a carrier oil like sweet almond, jojoba, or grapeseed oil. The National Association for Holistic Aromatherapy recommends about 15 drops of essential oil per ounce of carrier oil for a standard adult massage blend (a 2.5% dilution). Your birth partner can apply this to your lower back, shoulders, or feet during contractions. A footbath with a few drops of oil is another low-effort option that keeps the concentration on your skin minimal.
Avoid using a water-based room diffuser, especially if your baby will be born in the same room. Children’s Hospital of Philadelphia advises against room diffusers around young children because overexposure to aerosolized essential oils can irritate the lungs, eyes, and skin of newborns. A personal inhaler or cotton ball keeps the scent close to you without filling the room.
Oils to Avoid During Labor
Not all essential oils are safe for use around pregnancy and birth. Some carry specific reproductive risks:
- Pennyroyal, rue, savin, and wormwood have documented abortifacient properties and should never be used during pregnancy or labor.
- Myrrh, black seed (black cumin), and costus are classified as potentially toxic to the fetus.
- Cinnamon bark, oregano, lemongrass, and wintergreen have been associated with embryotoxicity, particularly at higher concentrations.
- Anise, fennel, and star anise can modulate reproductive hormones and are best avoided.
- Spanish lavender (distinct from true lavender) is classified as neurotoxic and should not be confused with the common lavender used in studies.
When purchasing oils, make sure you’re getting true lavender (Lavandula angustifolia), not a related species with a very different safety profile.
Setting Realistic Expectations
Essential oils are not going to replace an epidural. The pain relief they offer is real but modest. In the lavender trial, women in the aromatherapy group still reported meaningful pain, just less of it. Where essential oils seem to shine most is in managing the anxiety and fear that can make labor pain worse. Stress hormones like cortisol and adrenaline increase pain perception and can actually slow labor progress by working against oxytocin. Reducing anxiety through aromatherapy may help break that cycle.
Most women find essential oils most useful during early and active labor, before transition. As contractions reach peak intensity, many women lose tolerance for strong scents. Having oils available but not committing to them as your primary coping tool gives you flexibility. Pack them in your hospital bag alongside your other comfort measures, and let your birth partner know how you’d like them used so you don’t have to think about logistics in the moment.
