Is chamomile safe during pregnancy?

What does the evidence say about chamomile during pregnancy?

1. Chamomile is likely safe in the amounts found in tea and food, but not much is known yet about using it during pregnancy specifically. 1
2. Chamomile can trigger allergic reactions in people who are already allergic to ragweed, chrysanthemums, or marigolds, since they're related daisy-family plants. 1
3. Chamomile can interact with blood-thinning medications and cyclosporine, which matters given concerns about its effects on blood clotting near delivery. 2
4. Herbal supplement labels aren't required to be pre-approved for pregnancy safety or even for accuracy, so what's on the bottle may not match what's actually inside. 3

Is chamomile safe in each trimester?

• First trimester. One cup of tea now and then is fine in the first trimester. Skip concentrated capsules or essential oils unless your provider says otherwise.
• Second trimester. Same guidance as the first trimester. Some people find one cup helpful for mild insomnia, and pairing it with good sleep habits helps too.
• Third trimester. Stick to occasional cups rather than daily use. Some herbalists advise against concentrated chamomile close to delivery, though there isn't much human research on this specific concern.
