Certain herbal teas contain compounds that can be harmful during pregnancy, so it’s best to avoid teas like licorice, pennyroyal, and chamomile in excess.
Understanding Tea and Pregnancy Safety
Pregnancy introduces a whole new set of rules for what goes into your body. Tea, a beloved beverage worldwide, often raises questions about its safety during this delicate time. Not all teas are created equal; some contain ingredients that might pose risks to the developing baby or affect the mother’s health.
The key lies in recognizing which teas carry potentially harmful substances and which are generally safe. While traditional black and green teas are usually fine in moderation, many herbal varieties include herbs that can stimulate uterine contractions or have toxic effects.
Why Some Teas Can Be Risky During Pregnancy
Herbal teas derive their properties from various plants, roots, flowers, and leaves. Unlike conventional tea leaves from Camellia sinensis (black, green, white), herbal blends often lack standardization in their active compounds. Certain herbs naturally contain chemicals that influence hormones or blood flow.
For example, some herbs act as emmenagogues—agents that stimulate menstrual flow—and may increase the risk of miscarriage or premature labor. Others can cause allergic reactions or interfere with nutrient absorption.
The absence of strict regulations means the concentration of these compounds can vary widely between brands and batches. This unpredictability makes it crucial to know which herbs to steer clear of entirely.
Common Herbal Teas to Avoid During Pregnancy
Several herbal teas have earned a reputation for being unsafe or questionable during pregnancy. Here’s a detailed look at some of the most notable ones:
1. Licorice Root Tea
Licorice contains glycyrrhizin, a compound linked to increased blood pressure and reduced potassium levels. High intake may lead to preterm labor or developmental issues in the baby’s brain.
Studies have shown that excessive licorice consumption during pregnancy can result in lower birth weights and cognitive problems later in childhood. Even moderate amounts might pose risks, so it’s wise to avoid licorice tea altogether.
2. Pennyroyal Tea
Pennyroyal is notorious for its abortifacient properties—it has been used historically to induce menstruation or abortion. The oil extracted from pennyroyal is highly toxic and can cause liver damage or seizures.
Because of these dangers, pennyroyal tea is strongly contraindicated during pregnancy at any dose.
3. Chamomile Tea
Chamomile is widely consumed for relaxation and digestive aid but carries some concerns for pregnant women. It may act as a uterine stimulant in large quantities.
While occasional small servings are unlikely to cause harm, regular consumption should be avoided until more definitive safety data is available.
4. Raspberry Leaf Tea (Early Pregnancy)
Raspberry leaf tea is often recommended late in pregnancy to tone the uterus but should be avoided in the first trimester due to its potential to stimulate contractions prematurely.
Starting raspberry leaf tea too early could increase miscarriage risk, so timing is critical when choosing this particular herb.
5. Sage Tea
Sage contains thujone, which can trigger uterine contractions and neurotoxicity if consumed excessively. Pregnant women should skip sage tea entirely as a precautionary measure.
The Safety Profile of Popular Non-Herbal Teas
Not all teas carry significant risks during pregnancy. Regular black and green teas contain caffeine but no harmful herbal additives if consumed responsibly.
| Tea Type | Caffeine Content (per 8 oz) | Pregnancy Safety Notes |
|---|---|---|
| Black Tea | 40-70 mg | Safe in moderation; limit total caffeine intake. |
| Green Tea | 20-45 mg | Generally safe; watch caffeine limits. |
| Peppermint Herbal Tea | Caffeine-free | Usually safe; may relieve nausea. |
| Ginger Herbal Tea | Caffeine-free | Safe in moderate amounts; helps with morning sickness. |
Caffeine intake during pregnancy should ideally stay below 200 mg per day according to many health guidelines. This means enjoying one or two cups of black or green tea daily is generally fine but stacking multiple caffeinated drinks could push you over the limit.
Herbal teas like peppermint and ginger are popular choices because they’re caffeine-free and often help alleviate common pregnancy symptoms such as nausea and indigestion.
The Role of Herbal Compounds on Pregnancy Physiology
Some herbs influence hormone levels directly or indirectly affect uterine muscles:
- Emmenagogues: Herbs like mugwort and tansy can trigger menstruation by stimulating uterine lining shedding.
- Tocolytics: Some herbs theoretically relax uterine muscles but lack strong evidence.
- Toxins: Certain plants contain alkaloids that cross the placenta causing fetal harm.
- Blood Thinners: Herbs such as ginkgo may increase bleeding risk during delivery.
Because pregnancy involves complex hormonal shifts and placental development, any herb affecting these systems warrants caution unless proven safe through rigorous studies.
Navigating Labels: Identifying Unsafe Ingredients in Teas
Reading ingredient lists carefully helps avoid unexpected risks hidden within blends marketed as “natural” or “pregnancy-friendly.” Watch out for:
- Pennyroyal (Mentha pulegium)
- Dong quai (Angelica sinensis)
- Borage (Borago officinalis)
- Sassafras (Sassafras albidum)
- Lobelia (Lobelia inflata)
- Mugwort (Artemisia vulgaris)
These herbs appear occasionally in commercial blends aimed at women’s health but carry documented risks for pregnant women due to their pharmacological effects on the uterus or fetus.
Checking with reliable sources about each ingredient before consuming unfamiliar herbal blends reduces potential hazards significantly.
The Impact of Caffeine from Traditional Teas During Pregnancy
Caffeine crosses the placenta freely because fetal metabolism cannot break it down efficiently yet. Excessive maternal caffeine intake links with low birth weight, preterm birth, and miscarriage risks in some studies.
Moderation matters here:
The general recommendation caps daily caffeine consumption around 200 mg during pregnancy.
This amount roughly equals two cups of brewed black tea or three cups of green tea depending on strength. Decaf options provide alternatives without caffeine concerns but check labels since decaffeination does not remove all caffeine completely.
Balancing caffeine intake while satisfying cravings keeps both mom and baby safer throughout gestation.
The Benefits of Certain Herbal Teas When Chosen Wisely
Not every herbal tea spells trouble—some offer genuine relief from pregnancy discomforts without adverse effects if taken moderately:
- Peppermint: Eases nausea, indigestion, gas.
- Ginger: Well-known remedy for morning sickness symptoms.
- Lemon balm: Mild calming agent helping sleep quality.
- Nettle leaf: Rich source of vitamins but should be consumed cautiously after consulting expert advice.

Selecting trusted brands that avoid contaminants like heavy metals ensures safer consumption too since herbs absorb substances from soil variably depending on growing conditions.
Dangers Linked With Excessive Herbal Tea Consumption During Pregnancy
Overconsumption amplifies risks even with otherwise safe ingredients:
A high volume of any liquid can burden kidneys by increasing fluid load excessively.
Certain compounds build up over time leading to toxicity—for instance, excessive chamomile might cause allergic reactions despite occasional use being harmless.
The interaction between multiple herbs ingested simultaneously remains largely unknown; combining several types increases unpredictability.
Pregnant individuals should treat herbal teas like medications—mindful dosing matters greatly for safety’s sake.
Avoiding Contamination Risks: Quality Matters Most
Herbal products face fewer regulations than pharmaceuticals resulting in variable purity standards:
- Pesticide residues found occasionally due to farming practices;
- Mold contamination leading to mycotoxin exposure;
- Mislabeled ingredients causing unintended ingestion;
- Toxic plant substitutions mistaken for desired herbs;
- Bacterial contamination from improper processing;
- Heavy metals absorbed from polluted soil;
- Inconsistent active compound concentrations across batches;
- Possible drug-herb interactions complicating existing treatments;
- Risk amplified when buying loose-leaf blends without certification;
- Choosing organic certified brands reduces exposure risks significantly.
Pregnant women must prioritize trusted suppliers offering lab-tested products ensuring safety beyond marketing claims alone.
A Balanced Approach: When Is It Okay To Drink Tea?
Enjoying tea during pregnancy isn’t off-limits altogether if choices are made wisely:
- Limit caffeinated traditional teas under advised daily thresholds;
- Choose low-risk herbal options sparingly rather than routinely;
- Avoid known harmful herbs categorically at any dose;
- Monitor bodily responses carefully after trying new blends;
- Discuss unusual symptoms promptly with healthcare providers;
- Prefer freshly brewed over bottled commercial iced variants with additives;
- Stay hydrated primarily through water supplemented by safe beverages;
This measured strategy ensures comfort without compromising fetal wellbeing through inadvertent exposure to toxic agents found hidden within certain infusions.
