Pregnancy changes everything about how you look at your kitchen cabinet. Suddenly, that harmless box of herbal tea looks like a potential minefield of "is this okay?" or "will this cause a problem?" If you’re staring at a mug and wondering can you have chamomile tea while pregnant, you aren't alone. It’s one of the most common questions midwives get asked. Honestly, the answer isn’t a simple yes or no, which is frustrating when you just want to sleep or calm a jumpy stomach.
Most people assume "herbal" means "safe." That’s a mistake. While chamomile is the world’s favorite bedtime ritual, it contains bioactive compounds that interact with your body in ways we're still trying to fully map out during gestation.
The Gray Area of Herbal Safety
The FDA doesn't regulate herbal teas the same way they do medications. This is the crux of the issue. When you buy a box of chamomile, you’re getting a food product, not a clinical dose. This makes it incredibly hard for researchers to say, "X amount is fine, but Y amount is dangerous." Most doctors, like those at the American Pregnancy Association, suggest moderation, but that word is vague. What does moderation even mean when you’re dealing with a developing fetus?
Chamomile is basically a daisy. Specifically, Matricaria chamomilla. It's loaded with flavonoids, especially one called apigenin. Apigenin is great for anxiety because it binds to the same receptors in your brain as Valium. But in a pregnant body, things get complicated.
Why Some Doctors Wave a Red Flag
Let's talk about the scary stuff first because that’s what keeps you up at night. There is a specific concern regarding a condition called premature constriction of the ductus arteriosus. This is a blood vessel in the baby’s heart that needs to stay open until birth. Some studies, including research published in journals like Prenatal Diagnosis, have suggested that high intakes of polyphenols—which are found in chamomile—might cause this vessel to close too early.
If that vessel closes early, it can lead to pulmonary hypertension in the newborn. It’s rare. Extremely rare. But it’s the reason some high-risk OB-GYNs tell their patients to just skip the herbal teas entirely in the third trimester.
Then there’s the uterine issue.

Chamomile is often cited as a mild uterine stimulant. In very large, concentrated doses, it could theoretically trigger contractions. We aren't talking about a single tea bag from the grocery store. We’re talking about medicinal-grade tinctures or drinking ten cups a day. Still, if you have a history of preterm labor or a "sensitive" uterus, your doctor might be extra cautious.
The Benefits You’re Probably Craving
It’s not all warnings and red tape. There’s a reason you want that tea. Pregnancy is exhausting.
The Sleep Struggle: By the second trimester, sleep feels like a distant memory. Chamomile’s sedative properties are legendary. For many, a small cup of weak tea is the only thing that stops the racing thoughts at 3 AM.
Digestive Drama: Bloating? Gas? Morning sickness that feels more like "all-day" sickness? Chamomile is an antispasmodic. It relaxes the smooth muscles in your gut. This can be a lifesaver when your organs are being squished by a growing human.
Anxiety Reduction: Pregnancy is a high-stress tightrope walk. Keeping cortisol levels down is good for you and the baby. If a ritualistic cup of tea keeps you from a meltdown, that has value.
How to Drink It (If You Decide To)
If you and your healthcare provider decide that the benefits outweigh the tiny risks, don't just grab any box. Quality matters.
Cheap tea bags often contain fillers or "natural flavors" that aren't disclosed. You want pure, organic chamomile flowers. You should also watch the steep time. A "strong" brew isn't your friend right now. Dip the bag for two or three minutes and pull it out. You want the flavor and a hint of the calm, not a chemical punch.
Avoid "herbal blends." These are the real culprits. A box might say "Sleepy Time" or "Moonlight Calm," but if you look at the back, it might have pennyroyal, blue cohosh, or goldenseal. Those are strictly off-limits during pregnancy. Stick to single-ingredient chamomile so you actually know what you’re putting into your system.
What the Research Actually Tells Us
Most of our data comes from observational studies or animal models. We don't do double-blind, placebo-controlled trials on pregnant women for obvious ethical reasons.
A study often cited in the Journal of Ethnopharmacology looked at the use of herbal medicines in pregnancy across various cultures. It found that while chamomile is used globally, there is a distinct "dose-response" relationship. Small amounts? Usually fine. Large, frequent amounts? That’s where the correlation with preterm birth or low birth weight starts to pop up in the data.
There’s also the allergy factor. Chamomile is in the Asteraceae family. If you have a ragweed allergy, pregnancy is a terrible time to find out you’re also allergic to chamomile. An allergic reaction—especially one involving inflammation or breathing issues—is a massive stressor on a pregnancy.
Better Alternatives for the Anxious
If the "what ifs" of chamomile are making you more stressed than the tea is worth, there are other paths.
- Lemon Balm: Generally considered safer and has a similar calming effect on the nervous system.
- Ginger: This is the gold standard for nausea. It’s much better studied and widely accepted by the medical community.
- Magnesium: Often called "nature's relaxant." A magnesium supplement (with doctor approval) or even a spray can help with sleep and leg cramps without the uterine concerns.
- Peppermint: Great for digestion, though it can sometimes trigger heartburn, which is already a nightmare in the third trimester.
The Final Verdict on Can You Have Chamomile Tea While Pregnant
The consensus among modern midwives and doctors is that an occasional cup of weak chamomile tea is likely safe for most healthy pregnancies. However, "occasional" is the operative word. This isn't your daily water replacement.
If you are in your third trimester, the risk of heart-related complications for the baby, while small, is at its highest. Many practitioners suggest switching to plain hot water with lemon or a different fruit-based tea during these final weeks just to be safe.
Always listen to your body. If you drink a cup and feel increased Braxton Hicks contractions or just feel "off," stop. Your intuition is a powerful tool.
Actionable Steps for Your Pantry
- Check the label: Ensure the only ingredient is Matricaria recutita or Chamaemelum nobile.
- Limit your intake: Keep it to one cup, no more than two or three times a week.
- Shorten steep times: Two minutes is plenty to get the flavor without over-extracting the compounds.
- Consult your OB/Midwife: Mention it at your next check-up. They know your specific medical history and can give a personalized green light.
- Avoid in the third trimester: Consider switching to ginger or raspberry leaf (once you hit the 37-week mark) to avoid any potential impact on the baby's heart development.
- Watch for allergies: If you sneeze around daisies or marigolds, skip the chamomile entirely.
Staying informed is the best way to navigate these nine months. While the question of can you have chamomile tea while pregnant doesn't have a universal "yes" for every person, being cautious and informed allows you to make the best choice for your specific journey. Drink slowly, stay hydrated, and prioritize your peace of mind above all else.
