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.
Berberine is the main antimicrobial, hypoglycaemic and hypolipidaemic constituent. Notably, whole-leaf extracts are more potent against MRSA than isolated berberine (owing to efflux-pump-inhibitory flavonoids) and show quorum-quenching, anti-virulence activity.
Pharmacological Actions
Anti-inflammatory and astringent for inflamed mucous membranes (sore-throat gargle, mouth)
Antimicrobial (berberine) - supports skin, mucosal and gastrointestinal infections and sore throat

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).
Contraindicated in pregnancy and breastfeeding: berberine crosses the placenta and into milk and can cause or worsen newborn jaundice (risk of kernicterus); do not give to infants.
Berberine strongly inhibits drug-metabolising enzymes (especially CYP3A4 and CYP2D6), so it can raise the blood levels of many medicines - a significant herb-drug-interaction risk. In a screen of commercial herbal products, goldenseal was among the most potent CYP2D6 inhibitors and also inhibited CYP3A4. High doses have shown possible liver, nerve and photo-toxicity.

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]
Low, woodland perennial herb rising from a knotted, bright yellow rhizome with wiry yellow roots. Each stem bears two ragged, palmately lobed, maple-like leaves and a single small, inconspicuous greenish-white flower, followed by a raspberry-like cluster of red berries.[1]
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.
Grows in rich, shaded deciduous woodland with humus-rich soil; native to eastern North America, now scarce in the wild due to overharvesting and largely supplied by cultivation.[1]
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.
The rhizome and root are dug in autumn from plants at least three to four years old, when berberine content is highest, then cleaned and dried; because wild populations are depleted, cultivated or sustainably sourced material is strongly preferred, and careful identification against the toxic mayapple and bloodroot, which share its woodland habitat, is essential before any wild-harvesting.[1]
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]
Goldenseal root has a Native American and, after adoption by Eclectic physicians, wider North American tradition as a bitter tonic and antimicrobial remedy for mucous-membrane infections, sore throat, digestive upset and topical skin infections, directly reflecting its high berberine content.[1]
Preparations
Crushed or lightly crushed seed infused in hot water as a traditional carminative digestive tea.
Dried rhizome and root simmered in water as a traditional bitter antimicrobial tea, or used as a gargle for sore throat.
Tincture 1:10 in 60% ethanol of the dried rhizome and root, 2-4 ml three times daily per the WHO monograph Rhizoma Hydrastis. Educational reference only, not a prescription.
Extract standardised to berberine/hydrastine content, taken as capsules; whole-leaf extracts have shown stronger antimicrobial activity than isolated berberine in some studies.
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.
The WHO monograph on Rhizoma Hydrastis gives a daily dose of 0.5-1.0 g of the dried rhizome and root three times, or taken as a decoction; a 1:1 liquid extract in 60% ethanol at 0.3-1.0 mL three times; or a 1:10 tincture in 60% ethanol at 2-4 mL three times. For short-term use only, given goldenseal's potent CYP-enzyme inhibition and its contraindication in pregnancy. Educational reference only, not a prescription.
