Can clove tea help with pregnancy nausea or is it risky?

Clove tea has become a popular home remedy for digestive upsets and nausea—but what about pregnancy nausea? Here’s an evidence-based look at whether cloves can help ease queasiness in pregnancy, and what risks you should know before sipping.

Introduction
Pregnancy nausea (often called “morning sickness”) affects up to 70% of pregnant people, usually in the first trimester. While mild nausea can sometimes be managed with diet and lifestyle tweaks, more severe cases may require medical treatment. Many turn to herbal teas—like clove tea—as natural options. Cloves have long been prized for their warming, digestive-supporting properties, but can they safely ease pregnancy nausea?

What Are Cloves?
Cloves are the aromatic flower buds of the Syzygium aromaticum tree. They contain several active compounds—most notably eugenol—which give them anti-inflammatory, antioxidant and antimicrobial effects. In culinary use, cloves flavor meats, baked goods and hot beverages. In traditional medicine, they’ve been used to relieve indigestion, gas and toothache.

Potential Benefits of Clove Tea for Nausea
Although clinical trials on clove tea specifically in pregnant people are lacking, several properties suggest it might help mild nausea:

• Antiemetic effects
– Eugenol may help calm digestive tract spasms.
– Some lab studies show eugenol can reduce motion-sickness symptoms.

• Digestive support
– Cloves stimulate saliva and gastric juices, which may ease indigestion.
– Traditional systems (Ayurveda, Traditional Chinese Medicine) use cloves to warm the stomach.

• Antimicrobial action
– Cloves can inhibit certain bacteria and fungi in the gut, potentially helping overall digestion.

• Antioxidant benefits
– Clove’s polyphenols fight oxidative stress, which may indirectly support gut health.

Risks and Precautions in Pregnancy
While small amounts of cloves as a spice are generally safe in food, concentrated forms like tea or essential oil carry potential risks in pregnancy:

• Uterine stimulation
– High doses of eugenol may stimulate uterine contractions. Although rare, this raises concerns about preterm labor.
• Blood thinning effects
– Eugenol can interfere with blood clotting. If you’re already at risk for bleeding or taking anticoagulant medications, clove tea may heighten that risk.
• Allergic reactions
– Some people develop skin or respiratory allergies to clove compounds.
• Gastrointestinal irritation
– In large amounts, cloves can irritate the lining of the stomach, worsening nausea or heartburn.
• Drug interactions
– Eugenol can affect how the liver metabolizes certain medications, potentially altering their effectiveness.

What the Research Says
• Human studies on clove tea in pregnancy are essentially nonexistent.
• Animal studies show uterine-stimulating effects at high eugenol doses—levels far above what you’d find in a cup of herbal tea.
• Small clinical trials on non-pregnant adults suggest clove preparations can ease indigestion and nausea, but these results can’t be directly applied to pregnancy without further study.
• Traditional use patterns (e.g., in Ayurveda) recommend low, infrequent dosing for pregnant people to minimize any risk.

Safe Use Guidelines
If you and your healthcare provider decide a modest amount of clove tea may be worth a trial, follow these general precautions:

1. Use culinary-grade whole cloves.
2. Steep 1–2 whole cloves in 6–8 ounces of hot water for 5–10 minutes.
3. Limit intake to one small cup per day.
4. Avoid clove essential oil or high-strength extracts.
5. Watch for any signs of increased uterine activity (cramping, tightening).
6. Stop immediately if you experience dizziness, heart palpitations, headache or worsening nausea.
7. Discuss any medications you’re taking to rule out interactions.

Alternative Gentle Remedies
If you’d rather steer clear of cloves, consider these widely studied, pregnancy-friendly options:

• Ginger tea or capsules
• Small, frequent meals (dry crackers, toast)
• Cold lemon water or mint tea
• Acupressure wristbands
• Vitamin B6 supplements (under provider guidance)

Monitoring Symptoms and When to Seek Help
Most mild nausea improves by week 14–16 of pregnancy. However, if you experience any of the following, seek prompt medical advice:

• Persistent vomiting (more than three episodes per day)
• Inability to keep food or liquids down for 24 hours
• Weight loss greater than 5% of pre-pregnancy weight
• Signs of dehydration (dark urine, dizziness, rapid heartbeat)
• Severe abdominal pain or cramping
• Any unusual bleeding

Balancing Benefits and Risks
Clove tea in pregnancy sits in a gray zone: while a single small cup is unlikely to harm most healthy pregnancies, there’s not enough solid evidence to call it a proven anti-nausea remedy. If you’re desperate for relief, ginger remains the best-studied herbal option. If you prefer to experiment with cloves:

• Keep doses very low
• Pair it with provider oversight
• Track any symptoms closely

Speak to a doctor about any new herbal remedy—especially if you have a history of preterm labor, bleeding disorders or are taking medications.

Key Takeaways
• Cloves contain eugenol, which may offer mild antiemetic and digestive benefits.
• No direct clinical evidence supports clove tea for pregnancy nausea—use with caution.
• High doses risk uterine stimulation, blood thinning and gastric irritation.
• If used, steep only 1–2 whole cloves per cup, limit to one cup daily, and watch for side effects.
• Ginger tea, small meals and vitamin B6 have stronger safety and efficacy data in pregnancy.
• For any concerning symptoms, try a free, online symptom check, using the doctor approved Ubie Symptom Checker.
• Always discuss herbal remedies with your healthcare provider, and seek immediate care for severe or life-threatening signs.

Remember, every pregnancy is unique. What works for one person may not work for another. When in doubt, err on the side of caution—and speak to a doctor about anything serious or potentially life-threatening.
