Pregnancy Tea First Trimester

One of the most popular drinks in the world is tea, which many pregnant women continue to drink.

Some people drink it to unwind or to help them get the extra fluids they need during pregnancy. However, a certain percentage of women seem to utilize tea as a natural medicine for pregnancy-related symptoms or as a tonic in the latter weeks of pregnancy to get ready for giving birth (1Trusted Source).

Because tea is natural, many people might think that drinking it while pregnant is definitely safe. Actually, during pregnancy, women might benefit from cutting back on their use of some teas while altogether avoiding others.

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.

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.

Is it OK to drink tea in early pregnancy?

Tea has caffeine, which is widely considered okay during pregnancy as long as you consume it in moderation. About 200mg or 12oz of caffeine a day should be acceptable for most pregnant women. Even “decaffeinated” varieties have a little caffeine. Be mindful of the caffeine levels in the tea product you choose

What teas should you avoid when pregnant?

Experts advise caution with black, green, and oolong teas. Unlike herbal teas, which contain about 0.4 milligrams of caffeine per cup, these non-herbal teas can have up to 50 milligrams per cup according to the U.S. Department of Agriculture.

Limit your intake of caffeinated teas

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) (2Trusted Source3Trusted Source4Trusted Source5Trusted Source6Trusted Source):

  • 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 (7Trusted Source8Trusted Source9Trusted Source).

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

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 (8Trusted Source).

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 (10Trusted Source11Trusted Source).

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.

Certain herbal teas may have risky side effects

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 (11Trusted Source12Trusted Source13Trusted Source14Trusted Source15Trusted Source):

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

Menstrual bleeding

Teas that may stimulate or increase menstrual bleeding include (12Trusted Source16Trusted Source17Trusted Source):

  • motherwort
  • lovage
  • frankincense

Birth defects

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

  • 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 (1Trusted Source12Trusted Source).

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 (1Trusted Source).

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 (18Trusted Source).

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.

Some teas may be contaminated

Teas are not strictly tested or regulated. This means that women may be inadvertently drinking teas contaminated with unwanted compounds, such as heavy metals (19Trusted Source20Trusted Source).

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 (21Trusted Source).

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 (20Trusted Source).

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.

Teas that may be safe during pregnancy

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 (8Trusted Source11Trusted Source).

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

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 (1Trusted Source12Trusted Source18Trusted Source).

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 (11Trusted Source22Trusted Source).
  • 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 (12Trusted Source).
  • 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 (1Trusted Source12Trusted Source).
  • 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 (11Trusted Source).

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 (12Trusted Source23Trusted Source).

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

Teas that causes miscarriage during pregnancy

High dosages of parsley tea during pregnancy have been reported to trigger uterine contractions and even miscarriage. Herbal teas should be used with caution by expectant women, and they should first see a healthcare provider before include them in their diet.

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.

The bottom line

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.
