The Short Answer
Chamomile tea is considered safe to consume in moderation during pregnancy, but regular use — like drinking it every night before bed — has been associated with a higher risk of preterm birth and low birth weight. That’s the crux of the issue.
Generally speaking, it’s okay to have chamomile tea during pregnancy — but don’t overdo it. Try to keep it to 1 or 2 cups per day at most. The concern isn’t about the occasional soothing cup. It’s about making it a daily ritual without first talking to your doctor.
Health authorities like the National Institutes of Health (NIH) and the National Center for Complementary and Integrative Health (NCCIH) recommend that pregnant individuals speak with their healthcare provider before adding chamomile to their routine. That’s a reasonable step — and one that takes just a few minutes to check off.
Why It’s a Concern
Chamomile isn’t your average herbal tea. It contains more than 120 chemical secondary metabolites, including phenolic compounds like flavonoids, sesquiterpenes, and coumarins. During pregnancy, these compounds behave differently than they would in a non-pregnant body.
Here’s why that matters:
- Uterine stimulation: Chamomile has properties that stimulate uterine contractions, and ingesting too much of it can lead to preterm delivery and low birth weight.
- Estrogenic activity: Chamomile has affinity with estrogenic receptors through its coumarins, flavonoids, and phenolic compounds — and several of these have been detected to have, theoretically, more affinity than estradiol to estrogenic receptors.
- Fetal circulation risk: Constricted ductus arteriosus was detected in a 34-year-old woman at 20 weeks’ gestation who reported drinking chamomile tea on a regular basis — and her condition improved after stopping consumption of German chamomile tea.
- Medication interactions: Chamomile may interact with blood thinners like warfarin, increasing the risk of bleeding. While warfarin isn’t typically used in pregnancy, chamomile can interact with other medications you may be taking.
- Allergy risk: Chamomile is in the same plant family as ragweed, daisies, and marigolds — and people allergic to these may react to chamomile.
Important Note: The concern with chamomile during pregnancy is not caffeine — pure chamomile tea does not contain any caffeine. The real issue is its active plant compounds and their potential effects on your developing baby.
What the Research Actually Says
Here’s where it gets nuanced. The research on chamomile tea and pregnancy is limited — and that limitation itself is a key part of the story. A total of 23 studies involving 2,065 women from nine countries were included in one systematic review, but the development of clinical practice recommendations on using chamomile products during pregnancy is not feasible based on the available evidence.
What studies do exist point in a cautionary direction:
- In a retrospective study where risks of herbal products on pregnancy and neonatal outcomes were investigated, regular chamomile consumption during the third trimester was found to be associated with a higher risk of pre-term delivery and lower birth weight.
- A case report found that chamomile tea consumption during pregnancy led to premature constriction of the fetal ductus arteriosus in two pregnant women.
- One cohort study discovered a higher frequency of miscarriages (21.6%) and an increased risk of preterm labor (21.6%) among women who used chamomile.
On the other side of the coin, some surveys show women have used it with perceived benefit. A survey of women in Jordan revealed that chamomile tea was the most effective alternative treatment for managing GI symptoms during pregnancy, and an Australian survey concluded that 83% of women who used chamomile during pregnancy rated it helpful for nausea and disturbed sleep.
The key takeaway? While chamomile has been shown to be mildly effective at treating some disorders such as nausea, sleeplessness, and anxiety, there hasn’t been enough research to verify its safety during pregnancy. The studies that do raise red flags are enough to warrant caution — especially around the third trimester and with regular, heavy use.

Key Insight: Many sources link chamomile to early labor — but the study behind that claim used high doses of chamomile extract, not 1–2 cups of chamomile tea per day. Context matters enormously when reading headlines about herbal teas.
How to Do It Safely
If you’ve spoken with your doctor and gotten the green light, here’s how to enjoy chamomile tea during pregnancy in the safest way possible.
Recommended Amounts
Moderation is key — limit consumption to 1–2 cups per day. Official National Health Service advice is to have no more than 4 cups a day of any one herbal tea, but with chamomile specifically, staying closer to 1–2 cups is the wiser choice.
Trimester-by-Trimester Guidance
| Trimester | Guidance | Reason |
|---|---|---|
| First Trimester | Avoid or minimize | Some sources suggest chamomile may have mild uterine-stimulating effects, and while evidence is limited, it’s advisable to exercise caution during the first trimester. |
| Second Trimester | Occasional cup with doctor’s approval | Generally considered the lower-risk window; many experts suggest waiting until after the first trimester to introduce chamomile tea. |
| Third Trimester | Avoid regular use | Chamomile use during the third trimester was associated in one study with a higher incidence of preterm birth, shorter newborns, and low birth weight compared with non-users. |
Safe Preparation Tips
- Choose commercially prepared bags. Use commercially prepared chamomile tea if you choose to drink it during pregnancy — herbal teas that are commercially processed use herbs from safe sources.
- Go organic and reputable. Source your herbal teas from a reputable supplier to ensure you’re only ingesting high-quality, organic ingredients.
- Steep lightly. A shorter steep time (3–4 minutes) extracts fewer active compounds than a long steep. When you brew tea, you generally extract 30–40% of the active compounds in the leaf when you brew for 5 minutes — so a shorter steep means a gentler cup.
- Skip the concentrated forms entirely. Some small studies suggest that high-dose chamomile — specifically Roman chamomile in capsule or extract form, not tea — may stimulate uterine contractions. Stick to standard tea bags only.
- Check your blends. Always scan the back of the box to ensure every ingredient is safe. A “Sleepy Time” tea might combine chamomile with valerian root, which has less safety data.
Common Mistake: Assuming that because chamomile is “natural,” it’s automatically safe during pregnancy. Just because something is safe for adults doesn’t mean it’s safe for fetal development. Always check with your provider first.
When to Avoid It Completely
Even if chamomile is generally considered low-risk in moderation, there are specific situations where you should skip it entirely. Since chamomile has been associated with both miscarriage and premature labor, it definitely should not be used in large or medicinal amounts during pregnancy without first talking with your doctor.
Avoid chamomile tea completely if any of the following apply to you:
- You’re in your first trimester. The risk of uterine stimulation is highest when fetal development is most rapid.
- You’re in your third trimester. Studies showed that the risk of preterm birth and low birth weight was especially pronounced if chamomile was regularly consumed during the third trimester.
- You have a history of miscarriage or preterm labor. Any herb with even a theoretical uterine-stimulating effect is not worth the risk.
- You have a ragweed or daisy-family allergy. You should avoid chamomile tea if you have a known allergy to plants in the daisy family, which includes chamomile, ragweed, chrysanthemums, and marigolds.
- You’re taking certain medications. Chamomile may interact with high blood pressure and gestational diabetes medications. Various forms of chamomile extracts and supplements may also react with painkillers, sedatives, and antimicrobial drugs you might be taking during pregnancy.
- You’re experiencing any signs of preterm labor. Stop immediately and contact your healthcare provider.
Important Note: The U.S. National Institutes of Health, through the National Center for Complementary and Integrative Health, has stated that little is known about whether it’s safe to use chamomile during pregnancy and has not provided official guidance. When in doubt, leave it out.
What to Do Instead
If you’re craving something warm, comforting, and genuinely pregnancy-safe, you have great options. “Herbal teas can be a safe and effective way to improve some common pregnancy discomforts and a good sugar- and caffeine-free option for hydration.” You just need to choose the right ones.
Here are the best chamomile tea alternatives during pregnancy, matched to what you’re actually looking for:
For Nausea and Morning Sickness
Ginger tea is one of the most widely recommended teas for pregnancy. It’s known for easing nausea and morning sickness, especially during the first trimester, and is considered effective and safe in moderate amounts. Keeping it to around 1 gram of dried ginger per day is a good benchmark. Check out our guide to food and drink choices for more ways to manage pregnancy discomforts through diet.
For Sleep and Relaxation
Lemon balm tea is a safe option for pregnant women, offering a mild and pleasant flavor. It is known for its calming effects, which can help reduce anxiety and promote better sleep — both of which are beneficial during pregnancy. It’s a great swap for the bedtime chamomile ritual.
Rooibos tea is naturally caffeine-free, rich in antioxidants, and gentle on the stomach. It’s often used as a safe alternative to green or black tea. Its earthy sweetness makes it a genuinely satisfying evening drink.
For Digestion and Bloating
Peppermint tea is another go-to for pregnancy discomforts. It has a soothing effect on gastrointestinal issues in pregnant individuals, helping with bloating, gas, and indigestion. Pair it with a light meal or sip it after dinner. Staying hydrated also plays a huge role in digestive health — learn more about why drinking enough water matters every day.
For General Warmth and Comfort
You can make your own herbal tea by adding oranges, apples, pineapples, lemons, limes, pears, cinnamon, or mint leaves to boiling water or decaffeinated tea — it’s a simple, customizable, and completely pregnancy-safe ritual. Teas made from dried fruits like strawberries, raspberries (the fruit, not the leaf), apples, and citrus peels are generally safe, caffeine-free alternatives to juice, and great for hydration.
Pro Tip: Try ginger tea in the morning to help with nausea, peppermint tea after meals for digestion, and alternate between water, sparkling water, and a calming herbal tea throughout the day. Variety is your best strategy when pregnant.

Frequently Asked Questions
Is chamomile tea safe in the first trimester?
It’s best to avoid it during the first trimester. The first trimester is the most important period for fetal development — rapid cellular development in organogenesis can be affected by any compound, so special caution is needed while using herbal products during pregnancy. Most experts suggest waiting until the second trimester at the earliest, and only with your doctor’s approval.
Can chamomile tea cause a miscarriage?
High-dose chamomile supplements have been flagged as possibly unsafe in pregnancy due to theoretical miscarriage risk — but this caution is based on animal studies and limited human data. There is no strong evidence that occasional consumption of chamomile tea increases miscarriage risk. The risk appears to be dose-dependent, with concentrated forms being far more concerning than a standard cup of tea.
Can chamomile tea induce labor?
You may have heard that chamomile tea can induce labor, but there isn’t currently any medical evidence to support this. One randomized controlled trial found that overdue women taking chamomile capsules went into labor sooner than those given a placebo — but that study used a concentrated capsule form, not tea, and more research is needed to determine if similar effects occur with typical tea infusions.
How much chamomile tea is safe during pregnancy?
If your doctor has cleared you to drink it, limit consumption to 1–2 cups per day. Never exceed this without medical guidance, and avoid it entirely during the first and third trimesters unless specifically advised otherwise by your provider.
What’s the safest tea to drink while pregnant?
Some herbal teas, such as ginger and peppermint, are safe for pregnancy and even have some benefits, such as helping with nausea. Rooibos tea is naturally caffeine-free, rich in antioxidants, and gentle on the stomach — often used as a safe alternative to green or black tea. Lemon balm is another excellent option for calm and sleep support. Explore more about healing foods and drinks and how your diet supports your overall wellness.
Are chamomile tea blends safe during pregnancy?
Not necessarily. Because herbal products are not regulated in the same way as pharmaceuticals, the strength and purity of chamomile tea can vary from brand to brand. Tea “blends” are very common in coffee shops and on grocery shelves — make sure to check the ingredient list, as other herbs may be hidden in the blend. Always read the full ingredient list before drinking any blended herbal tea during pregnancy.
What if I accidentally drank chamomile tea before I knew I was pregnant?
Try not to panic. There likely isn’t any reason to panic if you find out you’ve accidentally had some tea that isn’t recommended for pregnancy. Most of the risks outlined are associated with regular and/or excessive use, so one stray cup shouldn’t put you or the baby in any danger. That said, do mention it to your healthcare provider at your next appointment for peace of mind.
The bottom line is this: chamomile tea isn’t automatically off-limits during pregnancy, but it demands more respect than most people give it. A thoughtful, informed approach — combined with an honest conversation with your doctor — is the best path forward. In the meantime, your kettle has plenty of safer, equally comforting options waiting to be explored.
