Can You Drink Peppermint and Licorice Tea When Pregnant?

If you are pregnant and craving a warm cup of herbal tea, you likely wonder whether peppermint and licorice tea is safe. The short answer is that peppermint tea is generally safe in moderate amounts, while licorice root tea is not recommended during pregnancy due to the compound glycyrrhizin, which may raise blood pressure and affect fetal development. However, many “licorice” teas on the market actually contain anise or fennel, not true licorice root, so reading labels carefully is essential. Below, we break down the risks and benefits of each tea, how much you can drink, and what to look for in blends.

Is Peppermint Tea Safe During Pregnancy?

Peppermint tea is widely considered safe for pregnant women when consumed in moderate amounts. Most healthcare providers approve up to one or two cups per day, especially during the first and second trimesters. The tea is made from peppermint leaves (Mentha × piperita) and does not contain the potent essential oils found in concentrated peppermint products.

That said, peppermint tea has a mild relaxing effect on the smooth muscles of the digestive tract. While this can relieve nausea and bloating, some women find that large amounts worsen heartburn because the lower esophageal sphincter may relax. If you have a history of heartburn or gastroesophageal reflux, start with a half cup and see how your body responds.

What Are the Benefits of Peppermint Tea for Pregnant Women?

Peppermint tea offers several practical benefits during pregnancy:

• Relieves morning sickness – The scent and taste can settle the stomach without medication. Many midwives recommend sipping cool peppermint tea when nausea strikes.
• Reduces bloating and gas – Peppermint helps relax intestinal muscles, easing discomfort from pregnancy-related digestive slowdown.
• Caffeine‑free alternative – Unlike coffee or black tea, peppermint tea contains no caffeine, making it a safe choice for women limiting their intake.
• Mild headache relief – The menthol may help ease tension headaches, though it is not a substitute for medical advice.

Be aware that these benefits apply to leaf peppermint tea, not extracts or highly concentrated peppermint oil. Avoid peppermint essential oil during pregnancy unless directed by a healthcare provider.

How Much Peppermint Tea Can You Drink While Pregnant?

Most studies and clinical guidelines suggest limiting peppermint tea to 1–2 cups (8 ounces each) per day. Exceeding this amount may increase the risk of heartburn or interfere with iron absorption if drunk with meals.

To drink it safely:

1. Choose organic peppermint tea bags or loose leaf to avoid pesticide residues.
2. Steep for 5–7 minutes in hot water (not boiling, to preserve flavor).
3. Drink between meals rather than with food to prevent any effect on iron absorption.
4. Stop use if you notice worsening heartburn or unusual uterine cramping.

For a convenient option, look for organic peppermint tea bags that are clearly labeled caffeine‑free.

Is Licorice Tea Safe During Pregnancy?

True licorice tea made from Glycyrrhiza glabra root is not considered safe during pregnancy because it contains glycyrrhizin. This compound can:

• Raise blood pressure by causing the body to retain sodium and lose potassium.
• Cross the placenta and potentially affect fetal hormone levels.
• Increase the risk of preterm labor in animal studies, though human data are limited.

The European Medicines Agency and several national health bodies advise pregnant women to avoid licorice root entirely. If you have high blood pressure or a history of preeclampsia, the risk is even greater.

Important distinction: Many commercial “licorice tea” blends use anise seed or fennel seed instead of licorice root. These are safe in typical amounts and taste similar. Always check the ingredient list for Glycyrrhiza glabra or “licorice root.” If it says “natural flavor” or “licorice flavor,” it’s likely anise.

What’s the Difference Between Licorice Root and Anise?

If you see a tea labeled “licorice spice” or “licorice blend,” confirm it contains anise or fennel. Otherwise, choose a brand that explicitly states “licorice root free.” For a safe option, consider organic anise seed tea which provides a similar flavor without the risks.

What About Peppermint and Licorice Blended Teas?

Blended teas that combine peppermint and “licorice” often rely on anise or fennel for the licorice note. These blends are usually safe if they do not contain actual licorice root. However, you need to verify the ingredients.

Peppermint + anise tea is generally well‑tolerated. Anise may help with digestion and has been used traditionally to promote milk supply after birth, though evidence is mixed.

Peppermint + true licorice root tea should be avoided. Even if the blend contains a small amount, the cumulative effect of daily drinking could be problematic.

To be safe, choose blends labeled “herbal tea for pregnancy” or “pregnancy tea” that have been formulated with safe herbs like peppermint, ginger, lemon balm, and anise. A pregnancy‑safe herbal tea sampler can help you try different flavors without worry.

Are There Any Risks of Peppermint and Licorice Tea During Pregnancy?

While peppermint tea is low‑risk, there are a few cautions:

• Heartburn – As mentioned, peppermint can relax the esophageal sphincter, causing acid reflux in some women.
• Uterine relaxation – Some sources suggest very large amounts (4+ cups daily) might contribute to uterine relaxation, though this is not confirmed. Stick to moderation.
• Allergic reactions – Rare, but possible if you are sensitive to mint family plants.
• Interaction with medications – Peppermint may increase absorption of certain drugs. If you take medication for thyroid issues or high blood pressure, ask your provider.

For licorice root tea:

• Blood pressure spikes – Glycyrrhizin can cause significant increases in blood pressure, even in women with normal readings.
• Potassium depletion – Low potassium can lead to muscle weakness, fatigue, and irregular heartbeat.
• Edema – Sodium retention from licorice root can worsen pregnancy swelling.

Because these risks outweigh any benefits, avoid licorice root entirely and choose safe alternatives.

What Herbal Teas Are Recommended During Pregnancy?

Several herbal teas are considered safe and helpful during pregnancy. Here is a quick checklist of common options:

• Ginger tea – Excellent for nausea and vomiting.
• Lemon balm tea – Calming and good for stress.
• Chamomile tea – Safe in moderate amounts (1–2 cups), though some advise caution in the first trimester.
• Rooibos tea – Naturally caffeine‑free and rich in antioxidants.
• Peppermint tea – As discussed, safe in moderation.
• Rose hip tea – Provides vitamin C.

Herbs to avoid during pregnancy include: sage (in large amounts), comfrey, pennyroyal, blue cohosh, black cohosh, and any tea with medicinal claims not approved by your provider.

What Should You Ask Your Provider Before Drinking Herbal Teas?

Before adding any herbal tea to your routine, have a short conversation with your midwife or obstetrician. Ask these questions:

1. “Does this tea interfere with my prenatal vitamins or iron supplements?”
2. “Are there any interactions with my current medications?”
3. “Is there a maximum number of cups I should stay under?”
4. “Are there any herbs I should avoid given my personal health history (e.g., high blood pressure, gestational diabetes)?”

Keep a food diary for a few days if you experience nausea, heartburn, or unusual symptoms after drinking tea. That helps your provider give personalized advice.

Final Guidance on Peppermint and Licorice Tea in Pregnancy

So, can you drink peppermint and licorice tea when pregnant? Peppermint tea is safe in moderation – up to two cups per day – and can help with nausea and bloating. True licorice root tea is not safe due to glycyrrhizin’s effects on blood pressure and potassium levels. However, many “licorice” teas are actually anise‑based and pose no problem. Always read the ingredient label: if it lists Glycyrrhiza glabra or “licorice root,” set it aside. Choose blends that list peppermint, anise, fennel, or other pregnancy‑safe herbs. And when in doubt, consult your healthcare provider before sipping. A warm cup of tea can be a comforting part of your pregnancy routine – just pick the right leaves.
