Is Sage Tea Safe During Pregnancy?

No, sage tea is best avoided during pregnancy because it may contain thujone, a potentially toxic compound, and its pregnancy safety has not been established. If you have already had sage tea, that does not mean it has harmed your pregnancy, but stop drinking it and discuss any concerns with your pregnancy care clinician.

What is the short answer?

Avoid sage tea as a precaution while pregnant, whether it is made from fresh sage, dried sage or a commercial tea blend. There is not enough reliable evidence to identify a preparation or amount that is safe during pregnancy.

This advice is different from saying that a cup of sage tea is known to cause harm. It means researchers have not established its safety well enough to recommend drinking it during pregnancy. The concentration of compounds in a cup can vary, so one product cannot be assumed to be equivalent to another.

Sage used in ordinary amounts to season food is different from drinking sage tea or taking a concentrated sage product. You generally do not need to avoid food simply because it contains sage as a seasoning.

Why might sage tea be unsafe during pregnancy?

Some sage preparations contain thujone, a naturally occurring compound that can be toxic at high exposures. The amount present depends on the type of sage and how the product is prepared. Its presence does not establish that a particular cup of tea will cause harm.

There is no reliable pregnancy evidence establishing that sage tea is safe for a pregnant person or fetus. The evidence available for this review does not include pregnancy studies, so it cannot show whether drinking sage tea causes pregnancy complications either. That uncertainty is the reason for a cautious recommendation, not proof of a specific outcome.

A label describing a product as natural, organic or caffeine-free does not establish that it is safe in pregnancy. Blends can contain several herbs, and the label may not tell you how much thujone ends up in the prepared drink.

Sage essential oil and concentrated extracts are not equivalent to culinary seasoning or a cup of tea. Concentrated products can result in much higher exposure to sage compounds and should not be taken during pregnancy unless a clinician specifically advises it.

How much sage tea is safe during pregnancy?

There is no established safe amount of sage tea for pregnancy. Because a safe limit has not been determined, it is not possible to recommend a number of cups, a brewing strength or a frequency that can be relied on as safe.

Making the tea weaker or drinking it only occasionally does not establish its safety. Likewise, changing from fresh sage to dried sage, or choosing a different brand, does not resolve the lack of pregnancy evidence.

If you want a drink for hydration, plain water is a straightforward choice. Water supports the organs that do most of the body's detoxification—the liver and kidneys—without requiring an herbal ingredient.

If sage appears in a tea blend, check the full ingredient list rather than relying on the product name. Ask your pregnancy care clinician or pharmacist about a product if you are unsure what it contains. Keep the packaging so they can see the ingredients and preparation directions.

When should you talk to your doctor?

Tell your doctor, midwife or other pregnancy care clinician if you have been drinking sage tea regularly, have taken a concentrated sage product, or are worried about an exposure. Let them know the product name, how it was prepared, approximately how much you had and when you had it. They can consider that information alongside your stage of pregnancy and medical history.

If you have epilepsy or a history of seizures, mention it when discussing sage exposure, particularly exposure to a concentrated product. Also tell your clinician or pharmacist about prescription medicines and supplements you take. Do not stop a prescribed medication because of a possible sage exposure without medical advice.

If you swallow sage essential oil or another concentrated sage product, contact a poison control service or a clinician promptly for advice; do not induce vomiting. In the United States, Poison Control can be reached at 1-800-222-1222. Call emergency services for a seizure, trouble breathing or loss of consciousness.

Seek urgent pregnancy care for severe abdominal pain, vaginal bleeding, fluid leaking from the vagina or reduced fetal movement once movements have become established. These signs need assessment regardless of whether you have consumed sage tea; do not assume that sage is the cause or wait for symptoms to pass.
