Can you drink hot tea while pregnant

Is Tea Safe During Pregnancy?

Tea is one of the most popular beverages worldwide — and one that many women continue to enjoy during pregnancy.

Some drink it to simply decompress or help meet the increased fluid needs of pregnancy. However, a proportion of women appear to use tea as a natural remedy for pregnancy-related symptoms or as a tonic to prepare for childbirth in the last weeks of pregnancy (1).

Many may believe that tea is probably safe to drink while pregnant because it’s natural. In reality, women may benefit from reducing their intake of certain teas, while completely avoiding others throughout their pregnancy.

This article discusses the safety of tea during pregnancy, including which teas pregnant women may continue to drink, and which they may want to avoid.

Black, green, white, matcha, chai, and oolong teas are all sourced from the leaves of the Camellia sinensis plant. They contain caffeine — a natural stimulant that should be limited during pregnancy.

They each provide approximately the following amount of caffeine per cup (240 mL) (2, 3, 4, 5, 6):

• matcha: 60–80 mg
• oolong tea: 38–58 mg
• black tea: 47–53 mg
• chai: 47–53 mg
• white tea: 25–50 mg
• green tea: 29–49 mg

Caffeine can easily cross the placenta, and your baby’s immature liver has difficulty breaking it down. As such, infants are more likely to experience side effects from amounts of caffeine that would otherwise be considered safe for adults.

Research suggests that infants exposed to too much caffeine during pregnancy may have a higher risk of being born preterm or with a low birth weight or birth defects. High caffeine intake during pregnancy may also increase the risk of miscarriage or stillbirth (7, 8, 9).

These risks appear minimal when pregnant women limit their caffeine intake to a maximum of 300 mg per day (8).

However, some women’s genetics may make them more sensitive to the ill effects of caffeine. For instance, research suggests that this small proportion of women may have a 2.4 times higher risk of miscarriage when consuming 100–300 mg of caffeine per day (8).

Caffeinated teas contain less caffeine than coffee and are generally considered safe to drink during pregnancy. However, their intake may need to be limited to avoid consuming too much caffeine per day (10, 11).

summary

Black, green, matcha, oolong, white, and chai teas contain caffeine, a stimulant that should be limited during pregnancy. Although they’re generally safe, women may benefit from limiting their daily intake of these caffeinated teas during pregnancy.

Herbal teas are made from dried fruits, flowers, spices, or herbs and therefore contain no caffeine. However, they may contain other compounds considered unsafe during pregnancy, which may result in risky side effects.

Miscarriage or preterm labor

Teas that may increase your risk of miscarriage or preterm labor include (11, 12, 13, 14, 15):

• fennel
• fenugreek
• sage
• vervain
• borage
• pennyroyal
• licorice
• thyme
• motherwort
• lovage
• blue cohosh
• black cohosh
• frankincense (in large amounts)
• chamomile (in large amounts)

Teas that may stimulate or increase menstrual bleeding include (12, 16, 17):

• motherwort
• lovage
• frankincense

Birth defects

Teas that may increase the risk of birth defects include (12):

• motherwort
• borage

Other side effects

Moreover, in rare cases, eucalyptus tea may cause nausea, vomiting, or diarrhea. What’s more, a case report suggests that regularly drinking chamomile tea during pregnancy may result in poor blood flow through a baby’s heart (1, 12).

Certain herbal teas may also contain compounds that interact with medications. Therefore, pregnant women should inform their healthcare providers of any herbal teas they are currently consuming or planning on consuming at any time during pregnancy (1).

Keep in mind that, due to the limited amount of research on the safety of herbal teas, a lack of evidence of negative side effects shouldn’t be seen as proof that the tea is safe to drink during pregnancy.

Until more is known, it may be best for pregnant women to remain cautious and avoid drinking any teas that have not yet been shown to be likely safe during pregnancy (18).

summary

Certain herbal teas may be linked to a higher risk of upset stomach, menstrual bleeding, miscarriage, birth defects, or preterm birth. Pregnant women may benefit from avoiding all teas not yet deemed as likely safe for pregnancy.

Teas are not strictly tested or regulated. This means that women may be inadvertently drinking teas contaminated with unwanted compounds, such as heavy metals (19, 20).

For instance, one study tested common off-the-shelf black, green, white, and oolong teas. It found that 20% of all samples were contaminated with aluminum. Moreover, 73% of all samples contained lead levels considered unsafe during pregnancy (21).

In another study, women with the highest intake of green and herbal teas during the first trimester of pregnancy had 6–14% higher blood lead levels than those who drank the least. That said, all blood lead levels remained within the normal range (20).

Due to the lack of regulation, there’s also a risk of herbal teas containing ingredients not listed on the label. This increases the risk that pregnant women end up inadvertently consuming a tea tainted with an undesirable herb, such as the ones listed above.

It’s currently impossible to eliminate this risk. However, you may somewhat minimize it by only purchasing teas from reputable brands.

What’s more, it’s likely best to avoid purchasing teas in bulk, as they have a higher risk of becoming mixed with tea leaves that may be contraindicated during pregnancy from adjacent bulk bins.

summary

The manufacturing of teas is not regulated. As a result, teas may become tainted with unwanted compounds, such as heavy metals or herbs that have been linked to poor pregnancy outcomes.

Most caffeinated teas are considered safe to drink during pregnancy, as long as they do not cause a woman’s total daily caffeine intake to exceed 300 mg (8, 11).

Women who are particularly sensitive to caffeine may benefit from aiming for a maximum of 100 mg of caffeine per day (8).

When it comes to herbal teas, there’s not a lot of research regarding their effects during pregnancy. As such, most health professionals advise pregnant women to avoid consuming any herb in amounts greater than you would find in foods (1, 12, 18).

That said, according to a few studies, herbal teas containing the following ingredients may be safe to consume during pregnancy:

• Raspberry leaf. This tea is considered likely safe and believed to shorten labor and help prepare the uterus for birth. Research shows that it may shorten the length of the second stage of labor, but only by about 10 minutes (11, 22).
• Peppermint. This tea is considered likely safe and commonly used to help relieve gas, nausea, stomach pain, or heartburn. However, no studies could be found to support these benefits (12).
• Ginger. Ginger is one of the most studied herb remedies during pregnancy and considered possibly safe. Research suggests it reduces nausea and vomiting but, when consumed dried, should not exceed 1 gram per day (1, 12).
• Lemon balm. This tea is considered possibly safe and commonly used to relieve anxiety, irritability, and insomnia. However, no study could be found to support these uses, and its safety hasn’t been studied in pregnancy (11).

Although generally considered safe, raspberry leaf may promote uterine contractions while peppermint may stimulate menstrual flow. Therefore, there’s some controversy regarding whether these teas are safe during the first trimester of pregnancy (12, 23).

Therefore, it may be best to avoid drinking these two teas in the first 12 weeks of pregnancy.

summary

Herbal teas considered to be possibly safe or likely safe during pregnancy include raspberry leaf, peppermint, ginger, and lemon balm teas. However, it may be best to avoid raspberry leaf and peppermint teas in the first trimester of pregnancy.

Despite their widespread popularity, not all teas are deemed safe for pregnancy.

Caffeinated teas like black, green, white, matcha, and chai teas are generally considered safe. However, their intake may need to be limited to avoid ingesting excessive amounts of caffeine.

Most herbal teas should be avoided. Raspberry leaf, peppermint, ginger, and lemon balm tea are the only ones currently deemed as potentially safe. However, women may benefit from avoiding the first two during their first trimester of pregnancy.

Herbal teas during pregnancy and breastfeeding

Many women choose to drink herbal tea to help with annoying symptoms when they're pregnant or breastfeeding. Some herbal teas are safe to drink while you're pregnant or breastfeeding, as long as you limit it to 1 or 2 cups a day and check with your doctor or midwife first.

Are herbal teas safe during pregnancy and breastfeeding?

Even though herbal teas contain natural ingredients, that doesn’t mean they are necessarily safe. The amounts of substances they contain may vary, and they may also contain ingredients that aren’t listed on the label. These ingredients may pass on to your baby, or they may interfere with other medicines you are taking.

Like other complementary medicines, herbal teas are not studied scientifically like other medicines and they aren't regulated in Australia, so it’s good to use them with caution.

There are mixed opinions on the safety of herbal teas, for both pregnant and non-pregnant women.

Most commercial brands of herbal teas are thought to be safe for anyone to consume in reasonable amounts. The herbal teas that are considered unsafe are those that are not made commercially, those made with excessive amounts of herbs (amounts larger than those found in common foods or drinks), and those made with herbs that are known to be toxic.

It's always a good idea to talk to your doctor and midwife before you take any natural therapy, including herbal teas.

About herbal teas

Some teas claim to soothe an upset tummy, calm you down if you have anxiety, prepare your uterus for labour, or help you sleep. Some teas are prepared especially for pregnancy, and claim to help with complications like pre-eclampsia and prepare your body for labour.

Herbal teas are made from the roots, berries, flowers, seeds, and leaves of plants. Unlike black or green tea, they don’t contain caffeine. They can be bought from supermarkets and health food stores.

Drinking herbal tea safely during pregnancy and breastfeeding

The best advice is to only drink 1 or 2 cups of herbal tea a day. Different teas contain different ingredients, so mixing up the flavours and drinking different types of tea on different days will limit the substances that your baby is exposed to. Don't drink the same herbal tea continually throughout your pregnancy.

If you're breastfeeding, keep an eye on your baby for any unusual side effects. If you notice anything that worries you, talk to your doctor or maternal child health nurse.

It's always a good idea to check before you take any herbs while you're breastfeeding, especially if you are also taking prescription medicine.

Which herbal teas to choose during pregnancy and breastfeeding

As a general rule, choose teas that are made from fruits and herbs you would use in cooking. Never make your own herbal tea from plants you've collected while you're pregnant or breastfeeding.

Large amounts of some herbs may possibly start contractions and increase your risk of preterm labour, or they may affect your baby.

Likely or possibly safe herbal teas

Peppermint tea: Peppermint is one of the most commonly used herbal medicines in pregnancy. Studies have shown it doesn’t harm the mother or baby, although you should avoid very large amounts and avoid in the first trimester because it can promote menstruation.

Red raspberry leaf tea: Some women drink raspberry tea during the last trimester to help them prepare for the birth. It should be safe in pregnancy, but some studies have shown it can stimulate contractions so it’s a good idea to be cautious during the first trimester.

Ginger tea: Ginger can help relieve nausea. It should be safe in moderation while you are pregnant or breastfeeding.

Green tea: Green tea isn't a true herbal tea. It contains caffeine, so you should limit how much you drink during pregnancy and breastfeeding.

Chamomile tea: A cup of chamomile tea before bed may relax you, but again, avoid drinking large quantities. There is a suggestion it could stimulate the uterus or lead to circulation problems in your baby.

Teas where there is insufficient information about safety

Rose hip tea: There isn't enough information on rose hip tea to know whether it's safe in pregnancy or breastfeeding.

Dandelion tea: There isn't enough information on dandelion tea to know whether it's safe in pregnancy or breastfeeding.

Lemon balm: This tea is considered possibly safe and commonly used to relieve anxiety, irritability and insomnia. However, no study could be found to support these uses, and its safety hasn’t been studied in pregnancy

Which herbal teas to avoid during pregnancy and breastfeeding

Sage tea: It’s OK to use sage in cooking, but you should avoid sage in concentrated forms during pregnancy such as in teas. It’s been linked to miscarriage and high blood pressure.

Parsley tea: Avoid parsley tea during pregnancy. If you drink large amounts, it may increase your risk of miscarriage and affect how your baby develops.

Contrary to popular belief that pregnant women should eat and drink " for two " , experienced doctors and midwives advise otherwise. According to gynecologist Christian Windelen from Cologne, one and a half to two liters of fluid a day is enough. It is better to drink boiled water, berry, fruit juices and drinks, various teas.

But tea is different for tea, so the choice of a healing drink should be treated very carefully. A detailed study of the use of herbs for the prevention and treatment of various diseases is carried out by a special area of ​​medicine - herbal medicine. nine0021 Unfortunately, it is quite difficult to thoroughly study the effect of herbal drinks on the body of pregnant women for ethical reasons, the German gynecologist explains.

However, based on years of observation, doctors recommend certain types of herbs during pregnancy. Moreover, herbal infusions can and should be used as a medicine, emphasizes Christian Vindelen. But black or green tea should not be carried away. The reason lies in theine, the so-called tea caffeine. With excessive use, it, like caffeine, can provoke a slowdown in intrauterine development of the fetus. nine0021

During pregnancy, no more than three cups a day

Based on the latest research on the benefits and harms of caffeine for pregnant women, the German Nutrition Society (Deutsche Gesellschaft für Ernährung) recommendations suggest limiting the invigorating drink to three cups ( black, green tea or coffee) per day. Christian Vindelen advises his patients during pregnancy to replace black tea with herbal infusions that can have a similar invigorating effect - for example, rooibos. nine0005

Midwife Martina Höfel from Minden has been advising expectant mothers for many years. Her favorite is herbal infusion made from raspberry and blackberry leaves. Tea has a mild stimulating effect on the walls of the uterus. It is better to drink it warm, not hot, starting from the 37th week of pregnancy, and no more than three cups a day.

Don't get carried away with such favorite herbal teas in Germany as mint, hibiscus or ginger root. All of them can contribute to premature uterine contractions, explains Martina Höfel. Drinks from plants with pronounced abortive properties should be completely excluded. These include verbena, rosemary, parsley, calendula, oregano, sage. It is better to refuse from such herbs widely used in folk medicine as St. nine0005

The best recipe - variety

Linda von Glahn, consultant of the UGB Healthy Food Association in Berlin, believes that the secret to the correct use of herbal drinks during pregnancy is simple: they need to be rotated more often. The recipe is not new at all, but effective. An ecotrophologist and expert in baby and pregnancy nutrition offers a range of well-known and undeniably useful plants to choose from.

These include, for example, fennel, chamomile, lavender and lemon balm, which have a beneficial effect on the functioning of the gastrointestinal tract. Chamomile and lavender have bactericidal and anti-inflammatory properties, help to relax. After a cup of this tea, it is easier and faster to fall asleep. nine0005 Rosehip decoction - a healthy drink for expectant mothers Photo: imago/imagebroker/Kröger

Rosehip decoction, like various fruit teas, is rich in vitamins and minerals. Freshly brewed infusions of fruits and berries strengthen the immune system. But the absolute favorite of ecotrophologist Linda von Glahn is rooibos (rooibos) tea. A drink made from the leaves of an African bush contains an impressive amount of antioxidants and various minerals. It is able to weaken the action of the stress hormone cortisol and positively influence the work of the happiness hormone serotonin. This is a real elixir of good mood, emphasizes Linda von Glahn. The Berlin expert once again reminds: infusions and herbal teas are medicines that should be used in moderation and better after consultation with an expert. nine0005
