Caraway
Caraway — what the European monograph actually supports, what it is not for, the form and how long it is meant to be used, side effects, and the absence of established medicine interactions documented for it.
This is a reference page, not a diagnosis and not a prescription. Herbal products are real pharmacology: they have effects, side effects and interactions with medicines. Tell your doctor and your pharmacist everything you take, including teas and supplements, and never stop or change a prescribed medicine because of anything you read here.
What it is
Carum carvi L. — fruit ("seed") and essential oil (Carvi fructus, Carvi aetheroleum)
Local names across the region this site serves: köömen (ET) · kumina (FI) · тмин (RU).
Grouped here under Digestion, bloating and the bowel. Regulatory position: EU herbal monograph — traditional use.
What the evidence supports
The registered indication: Mild spasmodic gastrointestinal complaints including bloating and flatulence.
The Baltic and Nordic bread and cheese spice with a genuine place in the trial literature. Its own registration is traditional use for bloating and cramping — the same modest carminative claim as fennel or anise. What lifts caraway above the rest of that group is a fixed combination: a standardised preparation of peppermint oil plus caraway oil has been tested in repeated randomised trials in functional dyspepsia, the picture of persistent upper-abdominal pain and fullness where investigation finds no ulcer, with consistent improvement in pain and pressure scores. That is a specific manufactured combination product, not two teas drunk together. A naming point that causes real confusion: caraway (Carum carvi) is not cumin (Cuminum cyminum), even though Estonian köömen and Russian тмин sit next to the cumin words in the spice aisle.
B — Traditional use, trials point the same way Registered on long-standing use, and independent reviews of human trials point in the same direction without settling the question.
What it is not for
Alarm symptoms in the upper abdomen — vomiting blood, black stools, difficulty swallowing, unexplained weight loss, or new symptoms after 50 — which need endoscopy, not a carminative.
Form, strength and how long
Whole or crushed fruit as an infusion, distilled caraway water, essential oil, and combination products with peppermint oil.
Duration. Short-term symptomatic use. Dyspepsia that persists for weeks deserves assessment.
No gram figure appears on this page on purpose. The plant part, the extraction solvent and the drug-to-extract ratio together define a preparation, and a number taken from one does not describe another. The reasoning is set out on the hub; the amount that applies to you is the one printed on the pack you are holding, and a pharmacist will read it with you.
Side effects
Rare allergic reactions, including cross-reaction within the carrot family (Apiaceae). Undiluted essential oil is irritant.
Who should avoid it
Essential-oil preparations are not for infants and small children. Culinary caraway in bread and cheese is a food and is not the concern here.
Interactions with medicines
No clinically important medicine interactions are established for this herb at culinary or tea amounts. That is not a guarantee — it means nothing has been characterised well enough to state. Concentrated extracts are a different exposure from a cup of tea, and the standing rule still applies: tell your pharmacist what you take.
The reverse view — start from the medicine rather than the plant — is in the medicine, food and alcohol interactions reference, and summarised for every herb on this site.
As a food
This one is also in the kitchen, so the nutrition figures are worth having next to the pharmacology: see the food data page for calories and nutrients per 100 g and per portion. Culinary amounts and medicinal preparations are different exposures, and the difference is usually the whole safety story.

Does caraway work?
Graded B here: Registered on long-standing use, and independent reviews of human trials point in the same direction without settling the question. Alarm symptoms in the upper abdomen — vomiting blood, black stools, difficulty swallowing, unexplained weight loss, or new symptoms after 50 — which need endoscopy, not a carminative.
How much caraway should I take?
This reference does not print gram figures, because they do not transfer between preparations of different extract strength. What can be said honestly is the form and the duration: Whole or crushed fruit as an infusion, distilled caraway water, essential oil, and combination products with peppermint oil. Short-term symptomatic use. Dyspepsia that persists for weeks deserves assessment.
What are the side effects of caraway?
Rare allergic reactions, including cross-reaction within the carrot family (Apiaceae). Undiluted essential oil is irritant.
Does caraway interact with medicines?
No clinically important medicine interactions are established for it, which is not the same as none existing. Tell your pharmacist what you take.
