Pregnancy-Safe Herbal Teas: Complete Guide

Swapping your usual coffee or wine for a warm mug of tea is one of the easiest pregnancy adjustments to make — but "herbal" doesn't automatically mean "safe". Some herbal teas are well tolerated in pregnancy, while others contain plant compounds that aren't recommended, particularly in larger amounts. Here's a practical, NHS-aligned rundown of what's generally fine and what to leave on the shelf.

Teas generally considered safe in moderation

Ginger tea — one of the most commonly recommended options for easing nausea and morning sickness. Most guidance supports moderate daily intake.
Peppermint tea — often used to settle the stomach and ease bloating or wind, both common pregnancy complaints.
Rooibos (redbush) tea — naturally caffeine-free and a popular swap for regular tea, as it doesn't contain the compounds found in true tea leaves.
Fruit teas — such as raspberry leaf (best left until later pregnancy — see below), strawberry, or blackcurrant infusions, which are usually just dried fruit rather than active herbal compounds.
Chamomile tea — commonly drunk in moderation, though some midwives suggest limiting it as it can have a mild relaxant effect.

As a general rule of thumb, moderation matters more than the specific herb — stick to a cup or two of any single herbal tea per day rather than drinking large quantities of one variety.

Teas to avoid or limit

Liquorice root tea — best avoided, as liquorice compounds are not considered pregnancy-safe in significant quantities.
Sage tea — traditionally associated with stimulating the uterus, so it's generally advised against, especially in early pregnancy.
Pennyroyal — this one is genuinely unsafe and should be avoided completely; it isn't a "limit it" herb, it's a "don't" herb.
Raspberry leaf tea — widely discussed for helping to prepare the uterus for labour, but most guidance suggests waiting until around 32-36 weeks, not using it in the first or second trimester.
Unlabelled "detox" or slimming teas — these often contain a mix of herbs, laxatives, or diuretics with no clear pregnancy safety data, so they're best avoided entirely.

How to shop and brew safely

Check the label for a clear ingredients list — avoid blends where you can't identify every herb.
Choose reputable, well-known brands rather than loose, unlabelled herbal mixes.
Stick to normal strength and avoid "double strength" or concentrated herbal preparations.
If a tea is marketed specifically for pregnancy (like raspberry leaf blends), read the recommended timing on the packaging, as many are intended for later pregnancy only.
When trying a new tea for the first time, have a small amount and see how you feel rather than drinking several cups straight away.

Frequently Asked Questions

Is ginger tea safe throughout pregnancy?

Yes, ginger tea is widely considered one of the safest and most useful herbal teas in pregnancy, particularly for easing nausea. It's generally fine to drink in moderate amounts throughout pregnancy, though if you're also taking ginger supplements or capsules, it's worth discussing total intake with your midwife or pharmacist.

Is chamomile tea safe in pregnancy?

Chamomile tea is generally considered acceptable in moderate amounts, such as a cup or two a day, and many people find it soothing for sleep or an unsettled stomach. Some midwives advise limiting it rather than drinking it constantly throughout the day, simply because data on high-volume use in pregnancy is limited. If you have any concerns, mention it at your next midwife appointment.

When can I start drinking raspberry leaf tea?

Raspberry leaf tea is generally not recommended in the first or second trimester because of its traditional association with stimulating the uterus. Most guidance suggests waiting until later in the third trimester, and even then, it's worth discussing timing and amount with your midwife first, especially if you've had any pregnancy complications.
