You’re staring at that box of Twinings in the pantry, wondering if a single cup of floral tea is going to cause a problem. It's a weird spot to be in. Pregnancy turns every tiny decision—like whether to have a second pickle or which tea bag to dunk—into a high-stakes research project. You've probably heard that chamomile is the "sleepytime" gold standard, but then you stumble across a forum post that mentions uterine contractions, and suddenly, you’re spiraling.
So, is chamomile tea safe for pregnancy?
The short answer is a frustrating "maybe." Or more accurately: "In moderation, probably, but there are some caveats you should definitely know about." Most OB-GYNs aren't going to freak out if you have an occasional cup, but chamomile isn't just flavored water. It’s a medicinal herb. It has active compounds that interact with your body in specific ways.
The big "Why" behind the caution
The reason doctors get twitchy about herbal teas isn't that they’re "toxic." It’s that we lack the massive, gold-standard clinical trials we have for things like Tylenol. Nobody is lining up 5,000 pregnant women and forcing them to drink gallons of chamomile just to see what happens. That would be unethical. Instead, we rely on smaller studies, animal data, and anecdotal evidence.
Chamomile contains things called flavonoids. Specifically, it's high in apigenin. In normal life, apigenin is great; it binds to GABA receptors in your brain to help you chill out. However, some researchers, like those contributing to the Journal of Obstetrics and Gynaecology, have looked into how these anti-inflammatory properties might affect a fetus. There is a specific concern regarding the ductus arteriosus—a blood vessel in a developing baby's heart that is supposed to stay open until birth. Some studies suggest that high doses of anti-inflammatories (like NSAIDs or very concentrated herbal extracts) could cause this vessel to close too early.
Does a tea bag contain enough apigenin to do that? Most experts say no. But that’s why "moderation" is the word of the day.
What's actually in your cup?
Not all chamomile is created equal. You’ve got German chamomile (Matricaria recutita) and Roman chamomile (Chamaemelum nobile). Most commercial tea bags use German chamomile.
- The Tea Bag: This is usually about 1 to 2 grams of dried flowers. When steeped for 5 minutes, the concentration of active oils is relatively low.
- The Tincture: This is a whole different ball game. Tinctures and concentrated extracts are way more potent. These are generally a "no-go" during pregnancy because the dose is high enough to potentially stimulate the uterus.
Honestly, if you're grabbing a standard box from the grocery store, you're dealing with a diluted version of the plant. But if you're buying loose-leaf "medicinal grade" flowers from an apothecary, you’re getting a much stronger hit of those phytochemicals.
Uterine stimulation myths vs. reality
You might see claims that chamomile is an "emmenagogue"—a fancy word for something that triggers menstrual flow. In massive, concentrated doses, some herbs can do this. For chamomile, the evidence is pretty thin for standard tea consumption. However, the Natural Medicines Comprehensive Database classifies chamomile as "possibly unsafe" during pregnancy when used in medicinal amounts precisely because it might act as a uterine stimulant.
Wait. Don't panic. "Medicinal amounts" means capsules or concentrated oils, not the soggy tea bag at the bottom of your mug.
Benefits that make it tempting
If you're dealing with third-trimester insomnia, chamomile feels like a lifesaver. It’s caffeine-free. It helps with the "pregnancy brain" anxiety. It also helps with digestion.

Many women suffer from GERD or acid reflux as the baby starts pushing your stomach up toward your throat. Chamomile is naturally carminative, meaning it helps settle the digestive tract. If a cup of tea keeps you from needing to pop four Tums, some midwives argue the trade-off is worth it.
What the experts say (The Nuance)
The American Pregnancy Association generally suggests that "commercial" herbal teas are okay in moderation. Dr. Mary Jane Minkin, a clinical professor of obstetrics and gynecology at Yale University, has often noted that while there isn't a ton of data, an occasional cup is likely fine.
The real risk is often "adulteration." Because herbal teas aren't regulated by the FDA like drugs are, sometimes they get cross-contaminated with other herbs that are definitely risky, like blue cohosh or pennyroyal. This is why you should stick to big, boring, reputable brands rather than "Mystery Pregnancy Glow Blend" from a random vendor at the farmer's market.
A note on the "Circular Logic" of safety
Here is how the logic usually goes in a doctor's office:
- Is there proof it's safe? No.
- Is there proof it's dangerous? Not really, unless you drink a gallon.
- Therefore, just drink water.
It's the safest path, sure. But it doesn't help when you’re wide awake at 3:00 AM and your legs are cramping.

Real-world guidelines for your kitchen
If you decide to keep is chamomile tea safe for pregnancy as part of your routine, here is how to do it with the least amount of risk:
- Limit your intake. We’re talking one cup, maybe two, once in a while. Not a liter every day.
- Keep the steep short. Three minutes is plenty. Don't let that tea bag sit in there until the water turns dark brown and bitter. The longer it steeps, the more compounds you extract.
- Watch for allergies. If you have a ragweed allergy, chamomile might give you a reaction. Pregnancy makes your immune system do weird things, so even if you were fine with it before, keep an eye out for any itchy throat or skin rashes.
- Second and third trimester focus. Most doctors are extra cautious in the first trimester when the baby's organs are just forming. If you want to be ultra-safe, maybe hold off until you hit the 13-week mark.
Alternatives if you're still worried
If the "what ifs" are ruining the relaxation of the tea anyway, try these instead:
- Ginger Tea: Probably the most "studied" tea for pregnancy. It’s the gold standard for morning sickness.
- Peppermint Tea: Great for bloating and gas, though it can sometimes make heartburn worse for some people.
- Lemon Balm: Often found in "calm" blends, it’s generally considered very mild, though again, moderation is key.
- Red Raspberry Leaf: WARNING. Do not drink this in the first trimester. It’s often used in the very end of the third trimester to help tone the uterus for labor, but you need to clear this with your midwife first.
Actionable steps for your next prenatal visit
Don't just take my word for it. Your body and your pregnancy are unique.
- Bring the box. Literally take the box of tea you like to your next appointment. Show your doctor the ingredient list. Sometimes "chamomile tea" is actually a blend containing hibiscus or lemongrass.
- Mention your dosage. Tell them, "I have one 8-ounce cup twice a week." That gives them a clear picture to give you a real medical opinion.
- Monitor your body. If you notice any increased Braxton Hicks contractions after drinking it, stop. Your body is a pretty good communicator if you listen closely.
Basically, chamomile is one of those "gray area" herbs. It isn't a poison, and it isn't a miracle cure. It’s a mild sedative from a flower. If a cup of tea helps you sleep after a week of exhaustion, the stress-reduction benefits might outweigh the theoretical risks. But if drinking it makes you anxious about the baby's safety, the tea has failed its primary job of relaxing you.
Stick to one cup, use a reputable brand, and always prioritize what your specific OB-GYN tells you over what you read on a screen.
Next Steps for Safety:
Check your tea cabinet for any "herbal blends" and ensure they don't contain hibiscus or liquorice root, as these are more strongly linked to potential pregnancy complications than chamomile. If you're looking for a sleep aid, try a magnesium supplement or a warm milk drink instead, as these have more established safety profiles for expecting mothers. Keep a "tea log" if you notice any changes in fetal movement or Braxton Hicks to help your doctor identify patterns.
