Caraway
Also known as: Carum carvi, caraway oil, caraway seed, carvone, Kümmel
Effective Dosage
25-50 mg caraway oil daily (typically combined with peppermint/L-menthol); 2 g seed powder studied for GI symptoms
What the Science Says
Caraway is a culinary herb whose seed oil has been studied as a digestive remedy. Clinical trials show it meaningfully reduces bloating, abdominal cramps, and indigestion symptoms — particularly when combined with peppermint oil (L-menthol) in a formulation called Menthacarin or COLM-SST. In patients with functional dyspepsia or irritable bowel syndrome, this combination produced significant symptom relief within 24 hours and sustained improvement over 4–8 weeks, with effect sizes considered clinically meaningful. It appears well tolerated with very few reported adverse events.
What It Doesn't Do
Won't replace medical treatment for serious GI conditions. No solid evidence it works as a standalone weight-loss supplement — the one study on body measurements used a complex AI modeling method and was conducted only in female athletes, making it impossible to generalize. No evidence it affects gastric emptying speed in healthy people. Don't expect it to work the same way on its own as it does in the peppermint oil combination studied in trials.
Evidence-Based Benefits
Caraway has been shown to aid digestion and reduce symptoms of gastrointestinal discomfort. It may also possess antioxidant properties and has been studied for its potential effects on reducing bloating and gas.

Absorption & Bioavailability
Unknown for caraway oil in humans specifically. Animal pharmacokinetic data (Beagle dogs) shows key compounds like psoralen and isopsoralen are absorbed within 0.5–2 hours with half-lives of 1.5–7 hours, but human data is not available from the provided studies.
Red Flags to Watch For
- Most clinical evidence is for caraway combined with peppermint oil — products selling caraway alone may not replicate studied effects
- Dried herbs including caraway have shown high pesticide contamination rates in food safety surveys; source quality matters
- Weight-loss claims for caraway are based on a single small study in female athletes using unconventional statistical modeling — not reliable evidence
- The pharmacokinetic paper (PMID 41814709) studied a different plant species also called 'Caraway' in Chinese medicine (Psoralea corylifolia), which is unrelated to Carum carvi — watch for mislabeled or misidentified products
