Can I eat Rosemary?

Rosemary can be consumed during pregnancy but requires caution. Safe in cooking; large medicinal doses may stimulate uterus. The key guidance from WHO: Use as seasoning only; avoid rosemary supplements or essential oil. Potential concerns include: May stimulate uterine contractions in large amounts. These risks are manageable when you follow the recommended limits.

A "Use Caution" rating means this food is generally fine during pregnancy but comes with a specific factor worth managing — a daily limit, a preparation requirement, or a moderation guideline — rather than a reason to avoid it outright. These ratings reflect general guidance from the FDA, ACOG, CDC, and USDA. The goal of the "caution" label is to flag what to pay attention to, not to suggest the food is unsafe when that factor is properly managed.

Culinary amounts of herbs and spices used in everyday cooking are considered safe during pregnancy — the caution that sometimes gets applied to "herbs" is really about medicinal or supplement-strength doses, which are a very different concentration than a pinch of the same herb in a recipe. Some herbs, like large amounts of licorice root, have been studied at supplement doses and linked to increased preterm birth risk; others are advised against in any amount as concentrated supplements. Because supplement-strength herbal products aren't regulated the same way food is, it's worth checking with your provider before starting any herbal supplement, even if the herb itself is a common cooking ingredient. As a general rule, if an herb or spice is something you'd use a teaspoon or tablespoon of in a recipe, it's a different category of exposure than a concentrated capsule, tincture, or extract of the same plant.

The caution around this food applies consistently across all three trimesters — there isn’t a specific window during pregnancy where it becomes more or less risky. The safest approach is moderation and attention to preparation or portion size throughout, rather than avoiding it in some trimesters and not others. If you’re managing a related condition, such as gestational diabetes or high blood pressure, ask your provider whether they’d recommend a stricter limit than the general guidance described here.

Beyond food-specific guidance, a few baseline food-handling habits reduce risk across everything you eat during pregnancy. These come from general FDA and USDA food-safety guidance rather than being specific to any one food, and they apply the same way in every trimester:
