During pregnancy, itโs important to be conscious of everything youโre putting in your body. We all know to be cautious about the common culpritsย (soft cheese, alcohol, caffeine), but a lot of people donโt realize there are herbs that arenโt safe for pregnancy. So before you ditch your cup of coffee for an herbal tea, make sure you know what ingredients areย safe for pregnancy.
Many people forget that herbs are the oldest form of medicine on earth. Before the boom of the pharmaceutical industry, herbs were prescribed for many ailments. I like to think of herbs as Mother Earthโs way of taking care of her creations (us humans). Itโs important we do not underestimate their power, and do not drink herbs โjust for funโ without understanding their properties.
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. Johnโs wort.

But other herbs arenโt as obvious and are commonly used in food, herbal tea, and mocktails. In Western medicine, many of these herbs are often recommended during pregnancy to support morning sickness, upset stomach, headaches, and nausea. However, in Eastern medicine, and among many herbalists, herbs such as Ginger are not recommended during pregnancy, especially during the 1st trimester. This is due to their emmenagogue and potential abortifacient effects.
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 before consumption, especially if you plan to consume them regularly or more than once daily.
A few common herbs to consider avoiding during pregnancy include Ginger, Lemon Balm, Peppermint, Rosemary, and Sage.

If youโre interested in learning more about herbs and contraindications, I highly recommend reading โHerbal Contraindications and Drug Interactionsโ by Francis J. Brinker.ย Here are a few highlights from the book, referencing the common herbs above and their respective contraindications:
Ginger
โAvoid 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.โ
Lemon Balm
โAvoid in pregnancy, due to its emmenagogue effect as well as its antithyrotropic and antigonadotropic activity.โ
Peppermint
โExcessive use should be avoided in early pregnancy, due to its emmenagogue effect.โ
Sage
โAvoid 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.โ
Turmeric
โAvoid in pregnancy, due to reported emmenagogue and abortifacient effects from its uterine stimulant activity (in vitro or in animals).โ
Reminder that 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.
If you find yourself still craving a cup of tea, try a slice of lemon with hot water or a decaf green tea. For non-alcoholic and pregnancy-safe mocktail options, check out โWhy โNon-Alcoholicโ Doesnโt Always Mean Safe During Pregnancyโ
