Is Aromatherapy SAFE During Pregnancy?

YES!

But there is a catch… not all are safe.

Throughout my career as a  maternal massage therapist, I’ve come to deeply appreciate the power of aromatherapy. When used thoughtfully, essential oils can calm the nervous system, ease physical discomfort, and promote emotional healing. However, during pregnancy, extra care is needed. The physiological changes occurring in the body, combined with the increased sensitivity many expectant mothers experience, mean we must approach aromatherapy with a heightened sense of safety and responsibility.

Aromatherapy involves the use of essential oils which are concentrated plant extracts. They can be used either through inhalation by a room diffuser or topical application. These oils can provide both physical relief and emotional balance. For pregnant clients, aromatherapy is often used to help manage common discomforts such as:

• Nausea and morning sickness,

• Fatigue and insomnia

• Stress and anxiety

• Backaches and muscle tension

• Swelling and poor circulation
  

While aromatherapy can be a supportive tool, the stakes are higher during pregnancy. Essential oils are potent, and their effects on a developing fetus aren’t fully understood. That’s why education, dilution, and individualization are crucial. Lets dive in to the factors that are considered while using aromatherapy in prenatal massage.

Timing. During the first trimester, the risk of miscarriage is highest, and the fetus is in its most vulnerable developmental phase. For this reason, many massage therapists and aromatherapists recommend avoiding most essential oils during these early weeks. Gentle massage without essential oils can still offer relief and connection.

From the second trimester onward, certain essential oils can be introduced, carefully and selectively, into massage therapy sessions or home routines. However some oils are avoided due to their ability to cause contractions. 

Dilution. Essential oils should always be diluted in a carrier oil before topical use, but this is especially important during pregnancy. A typical dilution for pregnant clients is 1% (about 5–6 drops of essential oil per ounce of carrier oil), compared to the more common 2–3% used for general adult use. Some oils are so strong that even lower dilutions may be necessary.

In my practice, I like to use Jojoba oil because it mimics the natural oil of our skin. 

Pregnant clients should never ingest essential oils or apply them directly to the skin undiluted. This can cause irritation, toxicity, or other adverse effects. 

Oils to Avoid Some essential oils can stimulate contractions, raise blood pressure, or interfere with hormone levels.

• Clary sage (unless used by a trained therapist once the baby is full term)

• Rosemary

• Cinnamon

• Thyme

• Oregano

• Wintergreen

• Basil

• Sage

Sensitivities.Pregnancy can increase sensitivity of smell and the skin. Sometimes an essential oil was very pleasant to a client before becoming pregnant and then nauseating while being pregnant.  When I use a new oil on a client,I will have them quickly sniff the essential oil to make sure they like it. Then I will do a patch test first to see if there are any adverse effects on the skin. 

Fortunately, there are many gentle essential oils considered safe during pregnancy when used properly.

Here are a few favorites that I’ve used in prenatal massage sessions and home care routines:

Lavender is a soothing powerhouse. It calms the nervous system, promotes restful sleep, and eases muscle tension. I often use diluted lavender oil in foot or neck massage during the second and third trimesters to help clients unwind.

Sweet orange is a powerhouse for uplifting  moods, easing anxiety, and helps with digestion. 

Chamomile is calming for both the body and mind. It’s particularly helpful for stress, irritability, and insomnia. Roman chamomile is milder than German chamomile and more suitable for pregnancy.

Frankincense is grounding and centering. It supports emotional balance and has mild anti-inflammatory properties.

Prenatal massage therapy and aromatherapy can offer powerful support, but they must be approached with care, knowledge, and respect for the changing body.

For massage therapists, this means continuously educating ourselves and maintaining open dialogue with clients and their healthcare providers. For pregnant individuals, it means listening to your body, honoring your intuition, and only working with trusted professionals.

Used wisely, essential oils can enhance relaxation, reduce discomfort, and provide moments of peace during pregnancy—a gift worth giving.
