During pregnancy, it’s important to be conscious of everything you’re putting in your body. We all know to be cautious about the common culprits (soft cheese, alcohol, caffeine), but a lot of people don’t realize there are herbs that aren’t safe for pregnancy. So before you ditch your cup of coffee for an herbal tea, make sure you know what ingredients are safe for pregnancy.
Some herbs to avoid during pregnancy might seem obvious, as they are uncommon and hard to come by. A few examples include ashwagandha root, blue cohosh, catnip, feverfew, and St. John’s wort.
But other herbs aren’t as obvious, and are commonly used in food, herbal tea, and mocktails. These include ginger, lemon balm, peppermint, rosemary, and sage.
If you are pregnant, breastfeeding, or taking medication, it is best to limit consumption to no more than one cup of herbal tea per day. While most herbs are safe in small doses, it is still best to consult your healthcare practitioner prior to consumption.
If you’re interested in learning more about herbs and contraindications, I highly recommend reading “Herbal Contraindications and Drug Interactions” by Francis J. Brinker. Here are a few highlights from the book, referencing the common herbs above and their respective contraindications:
Ginger
“Avoid using in pregnancy, due to its emmenagogue and potential abortifacient effects as shown by increased embryonic loss when ginger is consumed regularly as a tea (PO in rats). Some therefore indicate ginger should not be used for morning sickness, especially in large amounts. Use only with expert advice in this case.”
Lemon Balm
“Avoid in pregnancy, due to its emmenagogue effect as well as its antithyrotropic and antigonadotropic activity.”
Peppermint
“Excessive use should be avoided in early pregnancy, due to its emmenagogue effect.”
Sage
“Avoid in pregnancy, due to its emmenagogue and abortifacient effects and potential for fetotoxicity. It should not be used by nursing mothers, unless the intent is to stop milk flow.”
Turmeric
“Avoid in pregnancy, due to reported emmenagogue and abortifacient effects from its uterine stimulant activity (in vitro or in animals).”
The above list is just a select few of the many herbs that may be unsafe to consume during pregnancy. In general, it is best to avoid herbs while pregnant unless approved by your healthcare practitioner.
