Is It Safe to Use Jasmine Essential Oils While Pregnant

Jasmine essential oil is one of the most beloved aromatherapy oils in the world. Its rich, floral scent is associated with calm, warmth, and relaxation, and many women instinctively reach for it during pregnancy to ease anxiety or simply to feel more comfortable.

But is it safe to use jasmine essential oil while pregnant? The honest answer is: it depends on when in your pregnancy you are, how you use it, and whether you have professional guidance.

This article sets out exactly what the evidence says, what NHS clinical guidance recommends, and what you need to know before using jasmine oil at any stage of pregnancy.

What Is Jasmine Essential Oil?

Jasmine essential oil is extracted from the flowers of Jasminum officinale, a climbing plant native to South Asia and widely cultivated in countries including India and Egypt. The oil is highly concentrated and takes an enormous quantity of flowers to produce a small amount of pure oil.

It has a long history of use in traditional medicine and aromatherapy for:

• Reducing anxiety, stress, and tension

• Easing physical pain

• Promoting relaxation and sleep

• Supporting hormonal balance

• Encouraging uterine contractions during labour

That last property, encouraging uterine contractions, is precisely why jasmine essential oil during pregnancy requires careful consideration. It is a double-edged quality: genuinely useful at term and during labour under supervision, but potentially risky when used earlier in pregnancy without guidance.

Why Jasmine Oil Requires Extra Caution in Pregnancy

Essential oils are not mild substances. They are highly concentrated plant compounds that absorb through the skin and respiratory system. Some components can cross the placenta. In pregnancy, this matters because the developing baby is exposed to whatever enters the maternal bloodstream.

Jasmine essential oil, specifically, has properties that affect the uterus. Here is why that raises concern:

It can stimulate uterine contractions. This is one of jasmine oil's most studied and recognised properties. Research published in PMC via NCBI found that jasmine and salvia can increase oxytocin levels, a hormone that triggers uterine contractions, when used as aromatherapy. The same research noted that overuse may result in uterine hypertonicity and fetal distress. This is why jasmine is used deliberately by trained midwives to support labour, but should not be used at home in earlier pregnancy.

It influences hormone production. Jasmine oil may affect oestrogen levels and hormone balance. During pregnancy, hormonal fluctuations are already complex and tightly regulated. Introducing a substance that can alter those balances, particularly in the first trimester when fetal organ development is occurring, carries a theoretical risk that is not worth taking unnecessarily.

It can intensify contractions already underway. A review published in PMC via NCBI found that aromatherapy massage with jasmine extract significantly decreased pain severity during the first stage of labour compared to a control group. While this benefit is clear at term, the same mechanism that strengthens labour contractions becomes a risk factor earlier in pregnancy.

What NHS Guidance Says About Jasmine Oil in Pregnancy

Multiple NHS trusts and maternity services have published clear guidance on jasmine essential oil and pregnancy. The consensus is consistent.

Milton Keynes University Hospital NHS Foundation Trust published a Complementary Therapies in Maternity Care guideline (reviewed March 2024) that lists jasmine under oils that strengthen uterine contractions and stimulate expulsive contractions. Its guidance states: "Avoid until term pregnancy." The guideline also notes that jasmine is used only for massage, not inhalation or footbath, and specifies that midwives should take care when menstruating.

Gloucestershire Hospitals NHS Foundation Trust states in its patient information on essential oils and labour that jasmine essential oil is used for reducing anxiety and pain and may help speed up labour, but adds a clear caution: "This oil can have a strong effect and should not be used at home without professional guidance."

NHS Borders (Scotland) published an aromatherapy guideline for midwifery practice via NHS Right Decisions that identifies jasmine as high in ketones, advising that it should be avoided by women with insulin-dependent or gestational diabetes. It also specifies that jasmine is reserved for use by competent midwives, not for self-administration at home.

UK Teratology Information Service (UKTIS), which provides risk assessment guidance to NHS health professionals on substances used during pregnancy, states that there are no epidemiological or evidence-based studies on the safety of essential oils during pregnancy, and that risks from higher concentrations, such as those used in massage, cannot be ruled out.

The overall picture from NHS guidance is clear: jasmine essential oil should not be used during the first or second trimesters, and should only be used at or near term under professional midwifery supervision.

When Jasmine Oil Is Used in Pregnancy: Labour Only, Under Supervision

Here is the nuance that is important to understand. Jasmine essential oil is not banned outright from the maternity care setting. In fact, several NHS trusts actively use it, but only in specific circumstances.

At term pregnancy (from approximately 37 to 38 weeks), trained midwives in some NHS maternity units use jasmine oil as part of aromatherapy protocols to:

• Reduce anxiety and fear during labour

• Ease labour pain, particularly back pain

• Strengthen and encourage contractions during active labour

• Support labour progress in post-dates pregnancies

A study published in PMC via NCBI confirmed that jasmine oil massage was more effective in relieving labour pain than jasmine oil aromatherapy alone, with massage providing direct application alongside the olfactory (scent) effect.

The distinction between "safe at term under supervision" and "safe to use at home during pregnancy" is a large one. The same properties that make jasmine oil useful for supporting labour make it potentially hazardous when used freely throughout pregnancy.

First, Second, and Third Trimester: A Clear Guide

Here is a trimester-by-trimester breakdown of how jasmine essential oil should be approached.

First Trimester (Weeks 1–12)

Avoid completely.

The first trimester is when the embryo undergoes its most rapid and sensitive development, including the formation of all major organs, the nervous system, and the heart. This is the period of highest risk from any substance that can affect hormones, uterine tone, or placental function.

Clinical aromatherapy sources and NHS guidance both strongly advise against using jasmine oil in the first trimester. The Milton Keynes NHS guideline lists jasmine under oils that should be avoided in earlier pregnancy. A clinical aromatherapy resource cited by Clarity Blend, which references Essential Oil Safety by Robert Tisserand and Rodney Young (the most authoritative reference for health professionals in this field), recommends avoiding all direct-application essential oils in the first trimester as a precaution.

The guidance from Base Formula, a specialist aromatherapy supplier, specifically names jasmine among the stimulating oils that affect the uterus and hormones and should be avoided from the outset of pregnancy.

Second Trimester (Weeks 13–26)

Still not recommended for home use.

While the most critical period of fetal development has passed, the second trimester carries continued risks from uterine-stimulating oils. Jasmine's known effect on uterine tone and oxytocin production means it remains inappropriate for self-directed use at home. NHS clinical guidelines maintain the "avoid until term" position throughout the second trimester.

Third Trimester Before 37 Weeks (Weeks 27–36)

Avoid without professional guidance.

Some aromatherapists note that jasmine may be considered with caution from around 38 weeks, but the general clinical advice is to wait until labour has begun or is being actively managed by a midwife. Using jasmine oil independently at home before your due date and without medical monitoring carries the risk of triggering premature contractions or uterine hypertonicity.

If you are past 37 weeks and interested in using jasmine oil, speak to your midwife first. Do not self-administer.

At Term and During Labour (37+ Weeks, Under Midwife Supervision)

May be appropriate with professional guidance.

Jasmine oil has a genuine, evidence-supported role during active labour when administered by a trained midwife. Some NHS maternity units include it in their aromatherapy protocols. If your hospital or birth centre offers aromatherapy during labour, jasmine may be one of the oils available to you. Always use the oils provided and supervised by your midwifery team, not products brought from home.

How Essential Oils Affect the Body in Pregnancy

It helps to understand why essential oils are taken seriously as pharmacological substances, not just pleasant scents.

When inhaled, volatile aromatic compounds enter the lungs and pass into the bloodstream within minutes. When applied to the skin in a carrier oil, they absorb transdermally. Research cited by Happy Parents Happy Baby confirms that once inside the body, essential oils can trigger the release of endorphins, encephalins (natural pain relievers), and serotonin, as well as affect pulse rate, blood pressure, and respiration.

This pharmacological activity is what makes therapeutic aromatherapy effective. It is also what makes it necessary to treat essential oils as active substances during pregnancy rather than harmless background fragrance.

Essential Oils That Are Generally Safer in Pregnancy

If you are looking for aromatherapy support during pregnancy, several oils are considered lower-risk when used correctly and in appropriate dilution from the second trimester onwards. These include:

• Lavender (use with caution in the first trimester; generally considered safer from the second trimester for relaxation and sleep)

• Roman chamomile (soothing, mild, widely used for anxiety and tension in pregnancy)

• Neroli (citrus blossom; commonly used for anxiety and calming)

• Frankincense (used for anxiety and breathing support)

• Sweet orange (uplifting, used for nausea and mood support in labour)

Even these oils should be used at appropriate dilutions (1 to 2% in a carrier oil) and ideally discussed with a healthcare provider or qualified aromatherapist before use in pregnancy.

Oils that should be avoided throughout pregnancy include:

Jasmine, clary sage, rosemary, sage, cinnamon, clove, basil, cedarwood, cypress, juniper, myrrh, nutmeg, and wintergreen, according to the clinical guidance compiled at Clarity Blend and cross-referenced with Tisserand and Young's Essential Oil Safety.

Safety Tips for Using Any Essential Oil in Pregnancy

If you choose to use any essential oil during pregnancy, these are the minimum safety precautions to follow:

• Avoid all essential oils in the first trimester. This is the period of highest risk and the most conservative advice from clinical sources.

• Always dilute. Essential oils should never be applied undiluted (neat) to the skin at any time, and especially not during pregnancy. A 1% dilution in a carrier oil such as sunflower, almond, or coconut oil is the maximum recommended for pregnancy.

• Do not ingest. Swallowing essential oils is dangerous and provides no therapeutic benefit that cannot be achieved more safely through inhalation or topical use.

• Use a diffuser sparingly. Inhalation via a diffuser is generally the gentlest route, but keep sessions short (30 to 60 minutes maximum) and ensure good ventilation.

• Tell your midwife. Let your midwifery team know if you are using any aromatherapy products so they can advise based on your individual circumstances.

• Consult a qualified clinical aromatherapist. A practitioner trained in aromatherapy for pregnancy can give personalized guidance that generic online advice cannot.

Frequently Asked Questions

Can I use a jasmine-scented candle or perfume while pregnant?

Products containing jasmine fragrance at very low concentrations, such as perfumes, scented candles, and body lotions, are generally considered much lower risk than concentrated essential oil because the active compounds are present in far smaller amounts. The UK Teratology Information Service (UKTIS) notes that commercially available toiletry products containing low concentrations of essential oils (typically less than 0.01%) are not thought to increase the risk of adverse pregnancy outcomes. That said, strong fragrances can worsen pregnancy nausea. If a scent makes you feel unwell, avoid it.

Is jasmine tea safe to drink during pregnancy?

Jasmine-scented tea is very different from jasmine essential oil. The amount of jasmine transferred to tea through the scenting process is trace-level and is not equivalent to concentrated oil. Moderate consumption of jasmine tea is generally considered safe in pregnancy. The primary consideration with jasmine tea is its caffeine content if it is based on green or white tea, since caffeine intake should remain below 200 mg per day during pregnancy as per NHS guidance.

What happens if I accidentally used jasmine essential oil in early pregnancy?

A single, brief accidental exposure to jasmine essential oil in early pregnancy at a typical aromatherapy dilution is very unlikely to cause harm. UKTIS confirms that topical exposure to essential oils during pregnancy would not be regarded as medical grounds for additional foetal monitoring in an otherwise uncomplicated pregnancy. If you are concerned, contact your GP or midwife for reassurance and note the exposure. Do not use it again until you have sought professional guidance.

Are essential oils safer to inhale than to apply to the skin during pregnancy?

Inhalation via a diffuser is generally considered gentler than topical application because the concentration entering the bloodstream is lower. Topical application, particularly during massage, delivers higher concentrations transdermally, which is why NHS guidelines specifically restrict jasmine oil to massage only and only in the hands of trained midwives. Diffusing jasmine at home during pregnancy is still not advised before term, even though inhalation carries a lower dose than massage.

How do I know whether a clinical aromatherapist is qualified to advise me during pregnancy?

In the UK, look for aromatherapists accredited by the International Federation of Aromatherapists (IFA) or the Aromatherapy Council. Specifically for pregnancy, seek practitioners who have completed additional training in maternity aromatherapy. Your midwife or a specialist women's health clinic such as myGynaePlus can point you toward qualified practitioners or provide in-house guidance from clinicians with relevant training.
