Evidence face-off — shared uses
| Condition | Caraway | Tansy | Verdict |
|---|---|---|---|
| Bloating | 1/10 | 1/10 | Comparable evidence |
| Indigestion | 1/10 | 1/10 | Comparable evidence |

Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
Seed essential oil dominated by carvone (giving the characteristic caraway aroma) and limonene, responsible for much of the carminative and antimicrobial activity.
Minor antioxidant constituents of the seed and aerial parts.
Thujone is the neurotoxic, safety-limiting constituent responsible for tansy's real internal-use toxicity.
Contribute to the plant's bitter taste and antimicrobial activity.

Safety, Cautions & Contraindications
Generally very safe as a food spice (normal culinary amounts).Tea (traditional use): The EU herbal monograph describes caraway fruit tea for bloating/flatulence and gives a typical adult infusion dose of 0.5–2 g in 150 ml hot water, 1–3× daily; if symptoms last >2 weeks, seek medical advice. Allergy caution: Avoid if you’re allergic to Apiaceae family plants (e.g., fennel, anise, celery, coriander, dill) or have known cross-allergies (the monograph also mentions mugwort/birch allergy). Gallbladder/bile problems: Not recommended if you have gallstones or other biliary disorders (caraway can stimulate bile flow). Pregnancy & breastfeeding: Safety isn’t well established for medicinal dosing, so not recommended as a “treatment” during pregnancy/lactation (food use is a different story). Children: The EU monograph does not recommend medicinal use under 12 due to lack of data. Essential oil caution: Caraway essential oil is highly concentrated—don’t self-dose internally; it can irritate and is easy to overdo.
Duke (2002) provides clinical evidence (score 2) for caraway as an appetite stimulant, cough suppressant, cholagogue, and bronchitis remedy, consistent with Commission E approvals. It demonstrates anti-Candida activity and antispasmodic effects on gastrointestinal smooth muscle. Recommended dose: 1.5–6 g of fruit daily, or 3–6 drops of essential oil. The herb is classified as generally safe with no known hazards at therapeutic doses, though it should be used cautiously in pregnancy due to mild emmenagogue activity (Duke, 2002).
CAUTION: Tansy is considered toxic in medicinal doses and is NOT recommended for internal use. Thujone can cause convulsions, liver and kidney damage. Contraindicated in pregnancy (uterotonic and abortifacient). External use (as insect repellent) is generally safe. For information and historical reference only — do not use internally.
Duke (2002) rates tansy as ++ but emphasizes important safety concerns. The plant contains thujone (a neurotoxic ketone) and camphor, making it potentially toxic with internal use. Documented activities include emmenagogue, abortifacient (score 1), and insecticide. Duke strongly cautions against internal use except under professional supervision, noting that historical cases of tansy poisoning have resulted in convulsions and death. Topical use as an insect repellent is safer but should still avoid prolonged skin contact due to the essential oil's sensitizing potential. Strictly contraindicated in pregnancy (Duke, 2002).

Botanical Description
Biennial (occasionally annual) herb with finely divided, feathery, carrot-like leaves similar to those of other Apiaceae. In its second year it sends up a branched, grooved, hollow flowering stem topped with flat compound umbels of small white or pinkish flowers, followed by the characteristic curved, ridged, strongly aromatic seeds (the familiar rye-bread spice).[4]
Aromatic perennial herb (Asteraceae), 50-120 cm tall, with erect, reddish, ridged stems. Leaves are finely divided, fern-like and strongly camphor-scented. Flat-topped clusters of small, yellow, button-like flower heads lack ray florets (petals).[11]
Habitat
Grows in meadows, grassy roadsides and waste ground on well-drained soils; native to Europe and Western Asia and widely cultivated as a spice crop.
Native to Europe and temperate Asia, widely naturalised elsewhere; grows on roadsides, waste ground, riverbanks and disturbed grassland.[11]
Harvesting
The seed is harvested in mid- to late summer of the second year, once the umbels have browned and dried, then threshed and dried further; leaves can be picked through the first year and the root dug in autumn of year one or spring of year two.
Flowering aerial parts are cut in summer, when in full flower, and dried for external/historical use; given this plant's real toxicity (thujone content) at internal doses, this record does not recommend or describe internal harvesting for medicinal consumption.[11]
Traditional Uses
Caraway seed is one of the classic Apiaceae carminative digestive spices, used traditionally for indigestion, bloating, flatulence and poor appetite, and, per the EU herbal monograph, for symptomatic relief of mild digestive complaints and bloating.[4]
Tansy has a long European history as a strewing herb, insect repellent and, historically, an internal vermifuge and emmenagogue, but its thujone and camphor content make internal medicinal use unsafe by modern standards. Today it is used, with caution, mainly as an external insect repellent; the traditional internal uses are recorded here for historical reference only, not as a recommendation.[11]
Preparations
Crushed or lightly crushed seed infused in hot water as a traditional carminative digestive tea.
Dosage
The EU herbal monograph describes traditional use of about 0.5-2 g crushed fruit (seed) per 150 mL hot water, 1-3 times daily, in adolescents, adults and elderly; not recommended under 12 years. Educational reference only, not a prescription.
Tansy is NOT recommended for internal use at any dose given its thujone content and documented toxicity (convulsions, liver/kidney damage) - internal use recorded here is for historical reference only. External use (e.g. as an insect repellent) should avoid prolonged skin contact. Educational reference only, not a prescription; strictly avoid in pregnancy.
