Quick summary

Caraway (Carum carvi) is a plant used traditionally and in research for various gastrointestinal and related symptoms. Clinical research is limited, with some human trials suggesting potential benefits, but evidence remains inconclusive or preliminary for most indications.

What is it?

Caraway is a biennial plant belonging to the Apiaceae family, known for its aromatic seeds commonly used as a spice and herbal remedy. It has a history of traditional use for digestive issues and is being studied scientifically for its potential effects on gastrointestinal health and other outcomes.

Traditional uses

  • Relief of digestive disturbances such as bloating, gas, and indigestion
  • Flavoring agent in food and beverages
  • Carminative properties to ease intestinal discomfort

Active compounds

Caraway contains several bioactive constituents including:

  • Essential oils (e.g., carvone, limonene)
  • Phenolic compounds associated with antioxidant activity
  • Other phytochemicals typical of the Apiaceae family

Potential benefits with evidence levels

  • Potential effects on gastrointestinal disturbances – Limited clinical evidence: A clinical trial in pulmonary tuberculosis patients on antitubercular treatment showed caraway (2 g daily) may relieve gastrointestinal disturbances but appeared less effective than ginger or peppermint (Latif et al., 2025).
  • Associations with body composition indices – Cross-sectional observational study: An observational study in coronary angiography patients found that individuals not consuming caraway had higher body fat percentage, though no causal relationship was established (Arabi et al., 2026).
  • Antioxidant properties – Chemometric and phytochemical analysis: Caraway contains phenolic compounds linked to antioxidant activity among Apiaceae family members (Ulewicz-Magulska & Wesolowski, 2023).
  • Food additive properties affecting acrylamide formation – Systematic review of food science studies: Caraway powder was found to increase acrylamide formation in bread, indicating caution for its use in food processing (Abedini et al., 2025).
  • Potential antispasmodic effects – Review of essential oils and phytochemicals, indirect evidence: Essential oils from Apiaceae species, including caraway, show antispasmodic activity (Heghes et al., 2019).

Side effects

Herbal products including caraway are generally well tolerated, but specific clinical safety data for caraway are limited. No direct evidence of adverse effects associated with medicinal or dietary use of caraway was identified in human clinical reports. Mild complaints have been reported in studies of herbal galactagogues, but these did not specifically involve caraway.

Drug interactions

No clinical data on drug interactions with Carum carvi were identified. Given the limited evidence, caution is advised when caraway is used concomitantly with conventional medications.

Who should avoid it

  • No specific contraindications for caraway use were found in the research data.
  • Due to lack of safety data, pregnant or breastfeeding women should avoid using caraway as a medicinal herb.
  • Individuals with known allergies to plants in the Apiaceae family should exercise caution.

Evidence limitations

  • Most evidence arises from limited clinical trials, cross-sectional studies, or in vitro/food science research.
  • High-quality randomized controlled trials on caraway’s clinical effects and safety are lacking.
  • Heterogeneity and lack of standardization in herbal preparations complicate clinical efficacy assessment.
  • No long-term safety or reproductive studies in humans have been reported.
  • Reported food science effects (acrylamide formation) do not translate into evidence for medicinal use safety or efficacy.
