Essential Oils and Pregnancy: What You Need to Know About Essential Oils When You’re Pregnant

During your pregnancy, you may feel at a loss when it comes to conventional medicine, which doesn’t always offer solutions to relieve everyday aches and pains. As a result, some of you turn to natural medicine, particularly aromatherapy. But be careful: even though essential oils are natural, they come with risks you should be aware of.

Here’s a quick overview of what you can and cannot do. This guide will answer all your questions about using essential oils during pregnancy and provide beauty tips, as well as a list of recommended cosmetic ingredients.

Which essential oils should you avoid or use during pregnancy?

The use of essential oils during pregnancy often raises legitimate questions among expectant mothers. While aromatherapy can offer many benefits, it is essential to be aware of the precautions to take, particularly due to the increased sensitivity of pregnant women and the need to protect the health of the unborn baby.

In fact, not all essential oils are risk-free during pregnancy. Certain substances found in these oils may pose potential risks to fetal development and the mother’s health. This is why it is crucial to be well-informed and to consult a healthcare professional before using essential oils during pregnancy.

  • Topical application is the preferred method (however, avoid abdominal massages, as these areas are close to the unborn baby).

  • Diffusing certain oils into the air is also possible using a suitable diffuser or vaporiser. You can also place a few drops of essential oil on a handkerchief or a stone and inhale the scent from time to time (inhalation).

  • Be sure to follow the usage instructions (appropriate dosages/methods of use) listed on the technical data sheet for each essential oil before use

Tips for staying beautiful and relaxed during pregnancy

Although pregnancy is a joyful time, it often comes with minor, perfectly normal discomforts that can wear down the expectant mother.

Here is a short guide to Aroma-Zone ingredients and examples of synergies that can help you relieve minor ailments during pregnancy (either on their own or as a supplement to your usual treatment).

Nausea

From the start of pregnancy until around the fourth month, pregnancy is sometimes accompanied by nausea. This is caused by an increase in certain hormones.

These discomforts can be alleviated by a few simple habits, such as:

  • Adjusting your diet: drink plenty of fluids, eat smaller, more frequent meals, and keep them light (4 to 6 small meals a day). Opt for snacks with fresh fruit and nuts: almonds, hazelnuts, walnuts…

  • Appropriate dietary supplements : taking magnesium in marine form—one capsule per day in a glass of water during a meal—can effectively relieve nausea. Similarly, the effectiveness of probiotics has been demonstrated at a dose of one 2.5 g packet per day for 30 days.

  • Acupressure : This technique, based on Chinese medicine, involves applying pressure to the body’s energy centres. Thus, applying light pressure to a specific point on the wrist can help alleviate nausea. This "anti-nausea" point is located on the inner side of the wrist, three finger-widths above the wrist crease.

  • The use of certain essential oils and hydrosols:

Organic Lemon Essential Oil

A digestive tonic, this essential oil has regulating properties for the liver and helps relieve nausea. It’s recommended for digestive or liver fatigue.

Ginger Essential Oil

Known for its anti-nausea properties, it is also beneficial for digestion and can help relieve gas and bloating.

Hair beauty and strength

During the nine months of pregnancy, hair is generally stronger and shinier; your hair is practically on a high thanks to the overproduction of certain female hormones: estrogens.

For all hair types

To care for, nourish, and preserve their shine, you can combine these ingredients in your homemade cosmetics:

  • Plant Oils: Baobab, Coconut, Jojoba, Monoï, Brazil Nut, Shea Oleate, Castor, Yangu...

  • Plant butters: Mango, Murumuru, Shea

  • Other ingredients : BTMS, Ceramides, Emulsifying Conditioner, Phytokeratin, Silk Proteins, Rice Proteins, Provitamin B5, Plant-based Silicone

For oily hair

Some women who are used to having oily hair may find that this tendency is amplified by hormones. In this case, don’t panic—a few carefully chosen cosmetic ingredients and appropriate beauty tips can help you feel truly well:

  • Feel free to use a gentle shampoo as often as needed.

  • Rinse your hair with cold water.

  • Gently squeeze out the excess water.

  • Once a week, use a regulating mask made with Rhassoul clay or neutral henna.

Skin care

For sensitive skin

As beautiful as it is, a pregnant woman’s skin is also more delicate. Some skin types get irritated easily and may even become intolerant to complex formulas.

For your cosmetics, opt for simple formulas with soothing active ingredients such as:

  • Plant oils and oil macerates: Baobab, Calendula, Cotton, Jojoba

  • Essential oils: German chamomile, Roman chamomile

  • CO2 extracts: Organic calendula, organic German chamomile, organic pomegranate, kiwi

  • Hydrosols: Cornflower, German Chamomile, Roman Chamomile, Orange Blossom

  • Clays: Rose, Red

  • Active Ingredients: Allantoin, Bisabolol, Organic freeze-dried mare’s milk, Organic mallow extract, Powdered honey, Provitamin B5, Plant-based squalane, Plant-based lanolin substitute

For oily, acne-prone skin

Sometimes pregnancy can cause oily skin accompanied by a few pimples and blackheads. These comedones (blackheads) result from the oxidation of excess sebum on the surface of our enlarged pores. Therefore, opt for non-oxidising, penetrating plant oils as well as purifying, mattifying, and sebum-regulating active ingredients.

For your skincare routine, cleanse your skin daily, morning and night, with a mild soap to prevent the buildup of impurities that can lead to infections.

Don’t hesitate to exfoliate followed by a facial steam once a week to rid the skin of toxins and dead cells while purifying it.

  • Plant oils: Jojoba, Macadamia, Hazelnut, Sesame

  • Essential oils : Lemon (be careful with sun exposure), True lavender, Tea tree

  • CO2 extracts: Jupiter's beard

  • Hydrosols: Witch hazel (astringent), Lavender (healing), Rosemary (sebum-regulating), Tea tree (purifying)

  • Clays : Fine yellow clay

  • Purifying active ingredients: Algo'zinc, Bacti-pur, propolis extract, burdock root powder

  • Mattifying active ingredients: Arrowroot, Bamboo sap, Alum powder

Health and Diet Tips

A high-fat diet can contribute to breakouts and excess sebum. So cut back on butter, cream, deli meats, pastries, and other treats high in saturated fats. Opt for foods rich in zinc, such as dried beans, nuts, red meat, and poultry.

Pregnancy face mask

Starting in the fourth month of pregnancy, small brown spots may appear on the face. This hyperpigmentation, caused by an excess of melanin, is the result of hormonal factors. Women with darker skin tones are more prone to this than those with fair skin.

Very often, these spots disappear after the baby is born, but this isn’t always the case. That’s why it’s better to “prevent than cure”!

  • Plant oils and oil macerates : Macadamia, White Lily

  • Essential oils: Celery and Carrot

  • Brightening active ingredient: Vitamin C

Chloasma or pregnancy mask (D. Baudoux)

Sciatica and pain

Sciatica is caused by the pinching of the sciatic nerve. During pregnancy, the baby grows in the uterus and the pelvis widens. This can put pressure on the nerve, leading to pain and sometimes even immobility.

Sciatica should not be confused with lower back pain, which is caused by excess weight in the lower abdomen, leading to tension in the ligaments and back muscles.

Some osteopaths specialise in massage for pregnant women. Don’t hesitate to consult such a specialist if you experience sciatica during pregnancy.

In the meantime, you can relieve this pain by massaging the affected areas with essential and vegetable oils and other appropriate ingredients that promote muscle relaxation:

  • Oil macerates: Arnica

  • Essential oils: Lemon eucalyptus

  • Salts : Epsom salt, Dead Sea salts

Circulatory issues

1. What causes the sensation of heavy legs

The sensation of heavy legs is caused by poor blood circulation. When everything is working properly, small valves (located in the veins of the legs) ensure that blood flows back up to the heart.

Sometimes these valves become worn out and no longer function properly. This is what happens when you are in a standing position for long periods of time. Genetics also play a role; thus, it is not uncommon to see mothers and daughters suffering from this discomfort.

Pregnancy amplifies this phenomenon because during this period, a hormone called progesterone, secreted in greater quantities, promotes water retention and increases blood volume.

Under normal circumstances, excess fluid is drained by the lymphatic system. But during pregnancy, the volume of fluid in the bloodstream can become so high that the lymphatic system can no longer perform its balancing function. It becomes overwhelmed. This results in lymphatic edema, characterised by swelling of the toes and the appearance of skin folds.

2. Steps to Take to Prevent Heavy Legs

 But don’t worry—there are natural and effective solutions:

  • First, start by avoiding prolonged standing.

  • Walk regularly for about half an hour a day.

  • Avoid overly hot baths or overheated environments.

  • Elevate your feet at night.

  • Don’t hesitate to wear compression stockings (when the weather permits) and regularly massage your legs with firm strokes starting from the bottom of the ankle and moving up toward the top of the thigh.  

3. Natural products that promote blood circulation

Certain cosmetic active ingredients tone blood vessels and stimulate lymphatic circulation, helping to reduce the sensation of heavy legs and swelling.

  • Concentrated extracts: Red Vine, Butcher's Broom

  • Essential oils: Virginia Cedar, Lemon, Lime, Mastic

  • Vegetable oils: Macadamia, Rice Bran

  • Hydrosols: Peppermint, Provence Cypress, Witch Hazel, Juniper

Heartburn and acid reflux

Heartburn and acid reflux mainly occur during the second trimester of pregnancy when the growing baby presses against the stomach.

Here again, several natural remedies can provide real relief:

  • Essential oils: Roman chamomile

  • Clays: Illite green clay, which is gentler than Montmorillonite green clay

Quick tip: drink clay water

How to make clay water:

  • Mix one tablespoon of green illite clay or white clay into a glass of water.

  • Let the mixture sit for 6 hours.

  • Drink the clay water, being careful not to swallow the clay at the bottom of the glass.

Hyperacidity-Digestive Hypersecretion (D. Baudoux)

Preparing the perineum

Macadamia nut oil softens the pelvic floor muscles and makes them more elastic. You can therefore massage this area several times a day starting in the 8th month of pregnancy with macadamia nut oil to prepare it for childbirth.

Relaxing

The arrival of a baby and the changes to her body can cause anxiety for the expectant mother. Here are some essential oils and hydrosols that can help soothe stress.

  • Essential Oils: German Chamomile, Roman Chamomile, Clementine, Fine Lavender, Mandarin, Shell Marjoram, Neroli, Orange, Petitgrain, Ylang-Ylang

  • Hydrosols: Roman chamomile, German chamomile, Orange blossom, Fine lavender

Preventing stretch marks

The appearance of stretch marks is a major concern for pregnant women. To prevent them, you need to nourish the skin to ensure good elasticity and use oils and restructuring products.

To do this, opt for nourishing and reparative fats (oils and butters).

Aroma-Zone Quick Recipe: "Anti-Stretch Mark Whipped Butter"

To make your whipped butter, you need to:

1

Measure out the amount of shea butter and heat it in a double boiler to melt it.

2

Once the butter has melted, gradually add the other vegetable oils.

3

Finish by adding 4 drops of vitamin E.

4

Whisk with a mini whisk until the mixture is smooth.

The big day

Today, more and more midwives are turning to aromatherapy to support expectant mothers during childbirth. Don’t hesitate to bring this up during your prenatal classes, as certain essential oils can help promote a smooth delivery.

Managing Labour

One of the biggest fears for an expectant mother is the pain of childbirth. This pain can lead to tension and make the pain worse. It is therefore important to relax and unwind. Not easy given the circumstances… But a few breathing techniques combined with carefully chosen essential oils can help you do just that.

  • Essential oils: Lavender, Neroli, Petitgrain, Sweet Orange, Roman Chamomile, Shell Marjoram, Bay Laurel.

Quick Tip: The Benefits of Laurel

Laurel is a plant with powerful emotional and energetic properties. A symbol of victory (Caesar’s crown) and immortality, laurel—and especially its essential oil—brings courage and protection to each of us in the face of a struggle. Combined with relaxing essential oils like Neroli or Roman Chamomile, this essential oil gives you the courage and strength to face childbirth.

Psychological Support During Childbirth (D. Baudoux)

Strengthening contractions

Sometimes, the baby’s arrival is long-awaited, and labour isn’t progressing. This happens when the cervix is slow to dilate or when contractions are irregular or too infrequent. Essential oils are there to help you and stimulate contractions.

Of course, given their effects, these essential oils should not be used at any other time during pregnancy.

Quick Tip: Clove

Its Latin name, Eugenia caryophyllus, refers to Eugenia, the patron saint of midwives… Isn’t that a lovely hint of its virtues… This essential oil, which pregnant women should avoid during pregnancy, is one that wonderfully supports childbirth. In fact, in addition to relieving pain, this essential oil promotes uterine contractions and facilitates the baby’s delivery during childbirth. Combined with palmarosa essential oil, they form an indispensable duo in delivery rooms.

Strengthening contractions

A testimonial from Anne, mother of two

Inhaling fine lavender essential oil from a handkerchief during labour helped me cope better with the pain and allowed me to effectively use breathing techniques for relaxation. This enabled me to give birth to my little boy without an epidural...

The new mum’s must-have kit

Returning home from the hospital is sometimes accompanied by extreme fatigue, compounded by low spirits and the need to organise a new life. Those who are breastfeeding are even more affected, as they sometimes experience certain deficiencies (iron, calcium, etc.).

Very often, new mothers stop taking care of themselves. They eat on the go, get little sleep, and tend to forget that it is during these first few months after childbirth that healing and firming skincare is most effective.

Breastfeeding: Promoting Lactation

As a precaution, avoid applying essential oils to the breasts as much as possible while breastfeeding. But don’t demonise these essential oils either—some can be very useful, particularly for promoting healing or… stimulating milk production!

Milk secretion by the mammary glands depends on two hormones: prolactin and oxytocin.

Sometimes, some mothers do not produce enough milk to feed their baby. This insufficient milk production is generally due to a deficiency in one or the other of these hormones. However, keep in mind that true milk shortages are rare. Also note that the act of the baby suckling naturally stimulates milk production.

Fennel Essential Oil

 2 drops of fennel essential oil on 1/4 teaspoon of sugar (or in honey or on a neutral lozenge), to be allowed to melt in the mouth (the mother’s!) under the tongue, up to 3 times a day, for a few days.

Anise Essential Oil

The essential oils of Fennel and Anise have galactogenic properties; meaning they stimulate milk production. They should never be used during pregnancy, but can be used while breastfeeding to stimulate lactation.

Taking Care of Your Breasts

During breastfeeding, irritation and chafing may occur. Here are some Aroma-Zone ingredients to soften and nourish the skin and speed up healing. To avoid upsetting the baby, we recommend gently wiping the breast with a little of your milk before breastfeeding.

  • Plant Oils: Sweet Almond, Avocado, Calendula, Coconut, Raspberry, Rosehip

  • Plant-based butters: Mango, Shea

  • Other ingredients: Allantoin, Plant-based lanolin substitute

The Baby Blues

The first month after childbirth is an intense period when emotions can sometimes be amplified tenfold. Combined with certain self-care practices (yoga, sophrology, etc.), some essential oils and hydrosols can help you balance your emotions.

  • Essential Oils : German Chamomile, Roman Chamomile, Shell Marjoram, Neroli, Petitgrain, Damask Rose, Ylang-Ylang

  • Hydrosols: Rose, Ylang-Ylang

Quick tip: the rose

The rose symbolises love, passion and purity. Greek mythology tells us that the rose was born from the tears of the goddess of love, Aphrodite, who wept as Adonis lay dying. Because of its connection to spilled blood, the rose symbolises mystical rebirth or regeneration. It is also the plant most closely associated with femininity.

Rose essential oil and rose hydrosol are two essential ingredients for postpartum depression that will help you harmonise your mind, overcome your anxieties, and open yourself to love and tenderness.

Firming the bust and abdomen

During pregnancy, tissues become loose and muscles undergo significant stretching, which can cause some damage. The best way to regain a toned figure is to do some muscle-strengthening exercises as soon as your gynecologist gives the green light.

You can also improve your skin’s tone and vitality by choosing appropriate active ingredients such as:

  • Plant oils and oil macerates: Rosehip, Bellis

  • Hydrosols: Rockrose, Geranium

  • Other ingredients: Aloe vera gel

Tip of the Day: Kigelia Extract

Traditionally used as a beauty treatment by African women, kigelia contains active ingredients that tone and firm skin tissue. Renowned for stimulating breast development and shaping, it is used in many bust care products as a plumping and toning agent. This extract can be used as an active ingredient in your bust care products as soon as you stop breastfeeding.

Pelvic floor rehabilitation

During natural childbirth and even during pregnancy, the perineum—the muscular area responsible for supporting the pelvic organs (rectum, vagina, bladder)—is put to the test. The tissues become loose and sometimes struggle to regain their original tone, leading to issues such as urinary incontinence.

Perineal rehabilitation with a physical therapist or midwife is the best way to prevent future problems. A few sessions ofmuscle strengthening combined with massage using plant-based oils can ideally complement this care.

Perineal Tightening (D. Baudoux)

Treatment for stretch marks

The best way to prevent stretch marks is to keep your skin well-nourished during pregnancy.

If, despite your best efforts, a few stretch marks do appear during pregnancy, certain healing essential oils can be very helpful when blended with healing and nourishing plant oils.

Guide to using essential oils and hydrosols

How should you use essential oils?

  • For massage:In 50 ml of a carrier oil of your choice, add a total of 30 drops of essential oils of your choice. Massage into the neck area, preferably in the evening, to release all the day’s tension.

  • For room diffusion: Pour the essential oils into a diffuser. Diffuse for 10 minutes 3 times a day. You can also place a few drops of essential oils on a handkerchief or on your wrists and inhale deeply 2 to 3 times in a row.

  • In an aromatic bath: First, mix 15 drops of essential oil with 2 ml of Solubol. Pour your mixture into the bath. You can also add a few drops of essential oils to sea salt or Epsom salt before adding warm water to the bathtub.

How to use hydrosols

  • As a room mist: add the hydrosol to your misting bottle in place of water, or spray your hydrosol using a spray pump.
