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.
Flavonoid glycosides (e.g. isovitexin, vitexin, quercetin and apigenin derivatives), the main antioxidant constituents.
Caffeic, ferulic and related phenolic acids (antioxidant).
The defining sour constituent - oxalic acid with potassium and calcium oxalates - biosynthesised in part from vitamin C. Responsible for the sour taste and for the kidney-stone/oxalate caution.
High ascorbate content (basis of the traditional antiscorbutic use); also a metabolic precursor of the plant's oxalic acid.
Pharmacological Actions
Antibacterial and antiparasitic (amoebicidal/giardicidal) activity of woodsorrel extracts/constituents.
Protective against paracetamol-induced liver injury (congener O. corniculata).
Protective against experimental gastric ulceration (congener O. corniculata).
Woodsorrel phytoconstituents (and a green-synthesised nanoparticle made with O. stricta extract) induced apoptosis in breast, colon and Hep2 cancer cells (preclinical).
Alpha-glucosidase and alpha-amylase inhibition by woodsorrel extract (congener O. corniculata).
Anti-Alzheimer's activity of woodsorrel extract in rats (congener O. corniculata).
Promotes wound and fracture healing; traditional topical use for wounds and skin (congener O. corniculata).
Sour, tannin-containing herb; the basis of traditional antidiarrhoeal use.
Traditional astringent remedy for diarrhoea and dysentery (congener O. corniculata).

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).
Yellow woodsorrel is RICH IN OXALIC ACID and soluble oxalates (the source of its sour taste). Avoid large or frequent quantities, and especially avoid it if you are prone to calcium-oxalate kidney stones, have gout, or have kidney disease. Oxalates also bind calcium and iron, reducing their absorption. Use only modest amounts, and cooking reduces soluble oxalate.
Safety in pregnancy and breastfeeding has not been established; avoid medicinal doses during pregnancy and lactation.

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]
A small, sour-tasting herbaceous annual to short-lived perennial of the woodsorrel family, 10-40 cm tall. Its bright green leaves are clover-like, palmately divided into three heart-shaped (notched) leaflets that fold down at night and in strong sun. The small five-petalled flowers are bright yellow, borne in little clusters on axillary stalks. The whole plant tastes sharply sour from its oxalic-acid content. It is very similar to the creeping yellow woodsorrel (Oxalis corniculata) but has more upright stems that do not root at the nodes, and generally green (not purplish) foliage.[3]
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.
A common weed of disturbed, open and cultivated ground: gardens, lawns, arable fields, roadsides, footpaths, waste places and greenhouses. It favours moist, fertile, well-lit soils and is excluded by dense established vegetation. Native to North America but now naturalised almost worldwide across temperate and warm regions.[3]
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 sour leaves and aerial parts are gathered when actively growing and flowering, used fresh or dried. Because the plant accumulates oxalic acid, harvesting for food or medicine should favour young growth in modest quantities. As a low weed it is easily hand-gathered.[3]
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]
Yellow woodsorrel (Oxalis stricta and its near-identical relative O. corniculata) has a long folk-medicine history, deepest in South and East Asian traditions. The cooling, sour whole plant has been used as a refrigerant and thirst-quencher, as a sour leafy vegetable/condiment, and as a source of vitamin C against scurvy. Traditional medicinal uses (chiefly documented for O. corniculata) include dysentery and diarrhoea and other digestive complaints, fever, liver complaints, and topical application of the crushed leaves or juice to wounds, insect bites, warts, corns, mouth sores and inflamed skin, as well as use as a mild diuretic. O. stricta shares these uses where the two woodsorrels are not distinguished.[3, 4]
Preparations
Crushed or lightly crushed seed infused in hot water as a traditional carminative digestive tea.
Crushed fresh leaves or expressed juice applied topically to wounds, insect bites, warts and inflamed skin, or taken in small amounts for its cooling sour effect.
A whole-plant or leaf infusion/decoction used traditionally for fevers, diarrhoea and as a mild diuretic.
Young leaves eaten raw in small quantities as a tart salad green or to add sourness to food (edible 'sourgrass').
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.
