Can Clove Tea Cause Miscarriage? | What Science Says

No, moderate clove tea is unlikely to cause miscarriage, but strong brews and clove oil are best avoided in pregnancy without medical advice.

Herbal drinks feel gentle, so it can be unsettling to hear warnings that a simple cup of clove tea might threaten a pregnancy. Online stories range from reassuring to alarming, and many repeat claims without explaining where they come from or how strong the evidence is.

This guide walks through what is known about clove, how it behaves in the body, and how that relates to miscarriage risk. You will see where research is clear, where it is thin, and what practical steps make sense if you are pregnant and enjoy warm, spiced drinks.

Why People Worry About Clove Tea In Pregnancy

Clove comes from the dried flower buds of Syzygium aromaticum. It is rich in a compound called eugenol, which gives the spice its strong scent and numbing effect. Cloves appear in cooking, seasonal drinks, toothache remedies, and concentrated oils.

Several concerns feed the fear that clove tea could disturb a pregnancy:

• Hormone effects in lab and animal work. Some studies suggest clove extracts can influence estrogen and other reproductive hormones, though results vary and doses are far above typical food use.
• Uterine activity. Herbal texts often list clove as a plant that can stimulate the uterus. That raises questions about contractions and early pregnancy loss.
• Strong preparations. Clove oil and strongly concentrated teas deliver far more eugenol than a pinch of spice in food.

On the other side, major pregnancy health organizations stress that many herbs simply lack solid human data. The American Pregnancy Association notes that herbal teas are often treated as harmless even when safety data in pregnancy are limited and quality control varies from brand to brand.¹

Clove Tea Miscarriage Risk During Pregnancy

Right now, there is no high-quality human study showing that ordinary, food-level clove tea causes miscarriage. Articles that sound certain usually lean on three types of information: animal experiments with concentrated extracts, traditional herbal classifications, and theoretical concerns about how eugenol might behave at high doses.

Research on cloves and reproductive biology in animals has linked strongly concentrated extracts with shifts in hormone levels and changes in reproductive organs.² These results signal that clove is a pharmacologically active plant, but they do not prove that one or two weak cups of tea would trigger a loss in a human pregnancy.

Human safety data focus more on concentrated plant oils and medicinal use than on casual tea drinking. Reviews on herbal products in pregnancy note that many herbs show potent effects in lab settings, yet safe doses in pregnant people remain uncertain, so caution is advised for concentrated herbal products in general.

Putting these pieces together, most clinicians who work with high-risk pregnancies take a middle path: clove used as a normal kitchen spice is acceptable, while clove oil, supplements, and strong daily teas are treated as medicinal products that should be avoided unless a doctor or midwife specifically recommends them.

Forms Of Clove And How They Compare

Not every form of clove carries the same exposure. A light brew made with one or two cloves is a different situation from several teaspoons of clove powder or undiluted oil. Looking at the form you use helps you judge your personal level of risk.

Form Of Clove	Typical Use In Pregnancy	Main Safety Concern
Whole cloves in food	Occasional use in stews, rice, baked dishes	Considered low risk at culinary levels
Ground clove as spice	Small amounts in cakes, cookies, spice blends	Strong flavor makes high intake uncomfortable long before toxicity
Weak clove tea	One or two buds steeped briefly, not daily	Plausibly low risk, though human data are limited
Strong clove tea	Many buds or long steeping, often every day	Higher eugenol load; theoretical uterine stimulation and liver stress
Clove oil on skin or gums	Occasional spot use for toothache under dental advice	Rapid absorption; concentrated eugenol may affect blood clotting and irritate tissues
Clove oil swallowed	Home remedies, capsules, or drops	Not advised; linked with toxicity and profound uterine stimulation in lab models
Herbal blends heavy in clove	Spiced “detox” or “slimming” teas	Often unclear dosing and other herbs that may be unsafe in pregnancy

What We Know About Clove And The Uterus

Herbal reference works often describe clove as a warming spice that can bring on delayed periods. That reputation comes from both traditional use and biochemical studies showing that clove extracts can influence smooth muscle and hormone activity.²

Some plant databases even note that clove preparations can cause uterine contractions in animals.³ Those findings explain why many midwives, obstetricians, and herbalists err on the side of caution with strong clove products during pregnancy, especially in the first trimester.

At the same time, real-world data about miscarriages linked directly to clove tea are scarce. Reports that circulate online often lack clear dosing details, medical work-ups, or confirmation that clove played any role.

Because the stakes are high, many professionals use a simple rule: if an herb has strong pharmacologic effects and no clear benefit in pregnancy, avoid concentrated products and choose safer options. This approach matches broad advice from groups such as the U.S. National Center for Complementary and Integrative Health, which notes that many dietary and herbal supplements lack testing in pregnant women and that “natural” products can still carry risks.⁴

Safe Ways To Use Clove While Pregnant

If you enjoy the flavor of clove, you do not automatically need to banish every trace of it for nine months. The context and dose matter a great deal. These practical guidelines reflect how many obstetric providers and dietitians approach cloves in pregnancy.

Stick To Culinary Amounts

Using a pinch of clove in chai, mulled juice, curries, or baked goods fits within normal culinary intake. In that setting, cloves function more as a seasoning than as a herbal remedy. For most people with otherwise healthy pregnancies, this use is viewed as acceptable.

Be Cautious With Clove Tea

If you drink clove tea, keep it mild and not daily. Steep one or two buds briefly and avoid refilling the same strong pot. Skip bagged “detox” or “slimming” blends that list clove near the top of the ingredient panel.

Avoid Concentrated Oils And Supplements

Clove oil and clove capsules deliver far more eugenol than a cup of mild tea. Poison centers have recorded liver injury and other toxic reactions in children after clove oil ingestion, which shows how strong this product is.⁴ During pregnancy, swallowing clove oil or high-dose supplements is best avoided unless a doctor clearly prescribes them.

Talk With Your Own Clinician

Each pregnancy has its own history and medicines. If you have had losses, liver or bleeding problems, or you take blood-thinning drugs, even herbs in food may need special limits. A short conversation with your obstetrician, midwife, or pharmacist can help you decide whether occasional mild clove tea fits your care plan.

Other Herbal Teas That Are Safer Choices

Many pregnant people want a warm drink that settles the stomach, eases bloat, or replaces coffee. The safest choice is to favor herbs with better human data and long, ordinary use in pregnancy, such as ginger and peppermint, and to avoid herbs already linked with uterine contractions or hormonal effects in laboratory research.

When you pick a tea, check that the ingredient list names each herb, and avoid blends with vague terms like “proprietary mix,” where doses and plant species are not transparent.

Herbal Tea	Typical Pregnancy Use	Notes
Ginger	Nausea, morning sickness, digestion	Often chosen in modest daily amounts during pregnancy and studied for nausea.
Peppermint	Bloating, gas, mild stomach upset	Commonly sipped during pregnancy; some people notice more reflux if they drink large volumes.
Rooibos	Caffeine-free everyday drink	No known uterine stimulant effect; often used as a gentle black tea substitute.
Lemon balm	Mild tension and sleep	Used traditionally in pregnancy; modern safety data are still limited, so keep intake moderate.
Raspberry leaf	Late-pregnancy uterine toning	Sometimes suggested near term, but timing and dose should be cleared with your maternity team.

Practical Rules For Clove Tea In Pregnancy

When you put all the information together, a few simple rules can guide daily choices.

Think Dose, Frequency, And Form

The question is less “Is clove good or bad?” and more “How much, how often, and in what form?” Small amounts in food or rare mild tea cups sit in one category. Large amounts of clove powder, daily strong teas, or swallowed clove oil belong in another, where safety in pregnancy is uncertain.

Watch For Mixed Products

Herbal detox kits, slimming teas, and home mixes on social media may combine clove with herbs known to stimulate the uterus, such as blue cohosh or black cohosh. Information from safety reviews on herbal products and supplements in pregnancy shows that mixtures are hard to judge because ingredients can interact and labels may not match actual contents.⁴

Use Symptoms As Feedback

If you notice stomach pain, heartburn, mouth irritation, unusual bruising, or spotting after using a clove product, stop it and call your maternity care team. Those symptoms do not prove that clove is the cause, yet they signal that a clinician needs to review your herbs and medicines.

Keep Perspective On Risk

Miscarriage often results from chromosomal problems that no tea or spice could control. While strong clove products are best avoided, a mild, occasional clove tea is unlikely to decide the outcome of a pregnancy.

So, Can Clove Tea Cause Miscarriage?

Based on current evidence, ordinary culinary use of clove and occasional weak clove tea are unlikely to cause miscarriage. The greater concern lies with concentrated clove oil, supplements, and strong teas taken daily, where laboratory data raise valid questions and human research is minimal.

If you are pregnant and enjoy spiced drinks, favor gentler herbs with better safety data, keep clove in the kitchen instead of the medicine cabinet, and check in with your own clinician when decisions feel uncertain. This article offers general information, not personal medical advice, so your maternity team should always guide the final call for your situation.
