Are Essential Oils Safe During Pregnancy?
Published June 29, 2026 | By SafeMama Editorial Team | Editorial policy
The short answer: Some essential oils are pregnancy-safe; others are not. Many practitioners suggest avoiding essential oils altogether in the first trimester and being conservative throughout pregnancy. Concentration, route (diffusion vs topical vs ingestion), and the specific oil all matter.
Generally pregnancy-safe essential oils
Considered safe in moderation (properly diluted, after the first trimester unless noted):
- Lavender — relaxation, sleep, mild pain
- Roman chamomile — soothing, sleep
- German chamomile — similar
- Ginger — nausea (also fine as a tea)
- Peppermint — nausea, headache; use sparingly and avoid late pregnancy if breastfeeding plans require milk supply (can reduce milk)
- Citrus oils — lemon, sweet orange, mandarin, grapefruit (photosensitising — avoid sun exposure after topical use)
- Frankincense
- Neroli
- Petitgrain
- Ylang ylang
- Sandalwood
- Eucalyptus radiata (a milder eucalyptus species)
- Tea tree — topical, in dilution
- Geranium
Essential oils to AVOID in pregnancy
These have either documented uterine-stimulating activity or insufficient pregnancy safety data:
- Rosemary
- Clary sage (sometimes used to encourage labour — therefore avoid until term)
- Sage
- Jasmine
- Juniper berry
- Basil
- Parsley seed
- Pennyroyal (toxic, never)
- Cinnamon bark
- Fennel
- Hyssop
- Wintergreen (high salicylates)
- Mugwort
- Aniseed
- Thyme
- Oregano (in oil concentration — culinary use of the herb is fine)
- Wormwood, tansy, savin (toxic)
This is not exhaustive — when in doubt, check with your provider before use.
How to use essential oils safely in pregnancy
- Diffusion is the lowest-risk route. 30 minutes on, an hour off; well-ventilated room.
- Dilution for topical use: 1% (6 drops per 30 ml carrier oil) — half the standard adult dilution.
- Carrier oils: jojoba, sweet almond, coconut, grapeseed
- Patch test first. Pregnancy can change skin sensitivity.
- Avoid the abdomen (cautious default)
- Never ingest essential oils in pregnancy — this is a hard "no". Essential oils are not food-grade and are extremely concentrated.
- Photosensitising oils (bergamot, lemon, lime, grapefruit, orange) — avoid sun exposure for 12 hours after topical use.
First-trimester extra caution
Many aromatherapists recommend avoiding essential oils entirely in the first trimester (weeks 1–13), when the foetus is most vulnerable. Stick to non-EO comfort options: warm showers, light scent-free candles, basic moisturisers.
Common questions
Is lavender safe in early pregnancy?
Lavender is one of the most-used oils in pregnancy and is generally considered safe. Many practitioners still suggest waiting until the second trimester before regular topical use, and to keep diffuser use moderate.
Can I have eucalyptus for a cold while pregnant?
Eucalyptus radiata (the milder species) is generally considered safe for diffusion. Vapour rubs containing eucalyptus and camphor — read the label; some are labelled "not for pregnancy" and others are fine. Steam inhalation with a few drops in hot water is a common pregnancy-friendly approach.
What about peppermint for nausea?
Peppermint is widely used for pregnancy nausea — sniffing the bottle, a drop on a tissue, or peppermint tea. Effective for many; if it triggers reflux, switch to ginger.
Are essential-oil scented candles, soaps and laundry products safe?
These are very low concentration and generally fine. Avoid candles with named "avoid" oils (clary sage, rosemary, cinnamon) if you're being conservative.
