Is peppermint tea safe during pregnancy?

What does the evidence say about peppermint tea during pregnancy?

1. Peppermint, as both leaf and oil, has been used as a food and beverage for centuries and is generally recognized as safe in typical culinary amounts. 1
2. Concentrated peppermint oil is a different exposure than tea and can cause allergic reactions, heartburn, or interact with medications. 1
3. Peppermint relaxes the muscle that normally keeps stomach acid down, which can worsen reflux in some people: one reason those with heartburn often prefer ginger tea instead. 1
4. Always check the full ingredient list on herbal tea blends: multi-herb teas can include things like licorice root or senna that carry their own pregnancy caution, even when peppermint is the main flavor. 2

Is peppermint tea safe in each trimester?

• First trimester. Many people reach for peppermint tea in the first trimester for mild nausea. Ordinary cups haven't been linked to any specific harm in the research available.
• Second trimester. Moderate amounts are still fine. Peppermint can ease reflux for some people, but it can also relax the muscle that keeps stomach acid down, so check our heartburn guide if symptoms stick around.
• Third trimester. The same guidance applies. Avoid high-dose peppermint oil near delivery without talking to your provider first.
