Key Constituents
Seed essential oil dominated by linalool, giving the characteristic aroma and much of the antimicrobial and carminative activity.
Antioxidant flavonoids and phenolics, notably quercetin derivatives, identified across leaf and seed extracts.
Gives the leaf its characteristic sour taste; the basis for the caution around kidney stones and mineral absorption at high intakes.
Minor constituents typical of the Rumex genus, studied alongside other isolated compounds for antibacterial activity against Helicobacter pylori.
The basis for the plant's traditional antiscorbutic (anti-scurvy) reputation.

Safety, Cautions & Contraindications
• Food use is generally safe for most people (leaf in salads, seed as spice) (Burdock & Carabin, 2009). • Allergy is the main “big warning.” Coriander can trigger reactions ranging from mild oral itching to more serious allergy in sensitive people, especially those with pollen allergies (e.g., birch/mugwort) or other Apiaceae spice allergies (Thermo Fisher/Phadia, n.d.; Berghea et al., 2025). • If you use supplements (capsules/powder) and you take diabetes medication, be cautious: coriander seed powder has shown blood-sugar improvements in a small human trial, so it may add to the effect of glucose-lowering meds (Zamany et al., 2025). • Essential oil is not the same as the spice. Coriander essential oil is highly concentrated and should not be taken internally in “DIY doses.” It can be irritating, and safety data are discussed mainly for food-flavouring levels—not self-prescribed medicinal dosing (Burdock & Carabin, 2009). • Pregnancy / breastfeeding: normal culinary amounts are generally considered fine; “medicinal-dose” supplements or essential oil are best avoided unless guided by a qualified professional because safety data at higher doses is limited (Burdock & Carabin, 2009).
Duke (2002) provides clinical evidence (score 2) for coriander's role as an aperitif (appetite stimulant) and digestive tonic, consistent with Commission E approval. It demonstrates antispasmodic, carminative, and antifungal activities at the experimental level. Dose: 1–3 g crushed fruits (seeds) three times daily, or equivalent preparations. Duke notes mild hypoglycemic activity and a potential antiimplantation effect in high doses — use with caution in women attempting pregnancy (Duke, 2002).
High in oxalates (the sour taste): Large, frequent amounts can be a bad idea if you’re prone to kidney or bladder stones, or certain “rheumatic-type” complaints (Royal Botanic Gardens, Kew, n.d.). Moderation matters: Measured oxalate levels in leaves can be high, and researchers recommend treating sorrel more like an occasional delicacy than a daily staple (Tuazon-Nartea & Savage, 2013). Mineral binding: Oxalic acid can reduce how much calcium you absorb from a meal (Tuazon-Nartea & Savage, 2013). Sensitive stomach/mouth: Very sour leaves can irritate some people (common-sense caution; strongest source is the oxalate discussion above). Pregnancy/lactation: As a normal food herb in culinary amounts is generally considered fine, but avoid high-dose “medicinal” use because safety data are limited (Bello et al., 2019). Foraging safety (important): Sorrel can accumulate heavy metals depending on where it grows; avoid harvesting near roads/industrial areas (Gawęda, 2009).
Duke (2002) rates sorrel as ++ and notes diuretic, antiscorbutic (high vitamin C), and depurative activities at experimental and folkloric levels. The plant is traditionally used for anemia, fever, and scurvy prevention. High oxalic acid content is an important consideration — excessive consumption can promote kidney stone formation (oxalate stones) and may be harmful in individuals with gout or existing kidney disease. Duke advises limiting medicinal use and avoiding in those with a history of calcium oxalate kidney stones (Duke, 2002).

Botanical Description
Slender annual herb with delicate, broad, lobed lower leaves and finely divided, feathery upper leaves - a marked contrast within the same plant. Small white or pale pink flowers are borne in flat compound umbels, followed by round, ridged, aromatic seeds. The fresh leaf ('cilantro') has a distinctive citrusy aroma, often described as soapy by those with a genetic sensitivity to it.[4]
Perennial herb (Polygonaceae), 30-100 cm tall, with erect, often reddish, ridged flowering stems. Basal leaves are arrow- (hastate-) shaped with backward-pointing basal lobes, and sour-tasting from oxalic acid content. Tiny reddish-brown flowers are borne in narrow, branched spikes; the species is dioecious, with separate male and female plants.[11]
Habitat
Believed native to the Mediterranean region and Western Asia; cultivated worldwide as a culinary herb and spice crop on well-drained, sunny sites.[4]
Native throughout Europe and temperate Asia, common in meadows, grassland, pastures and roadside verges on a wide range of soils, tolerating both damp and dry ground.[11]
Harvesting
Leaves are picked fresh through the growing season, before the plant bolts (flowers), when the flavour is best; the seed is harvested in late summer once the umbels have browned and dried, then threshed; the root can be dug at the same time as young leaves.
Leaves are gathered fresh in spring and early summer, before flowering, when they are most tender and least bitter. Avoid harvesting near roads or industrial areas, given the plant's tendency to accumulate heavy metals.[11]
Traditional Uses
Coriander seed and leaf have a very long culinary and medicinal history across the Mediterranean, Middle East and Asia as a digestive carminative for indigestion, bloating and cramping, and, more recently, studied for calming/anxiolytic effects on the central nervous system alongside cardiovascular and metabolic benefits.[1, 4]
Common sorrel has a long European culinary-medicinal tradition as a refreshing, vitamin-C-rich spring green and digestive bitter, and folk-medicinally as a diuretic and mild antiscorbutic (anti-scurvy) remedy. Modern research confirms antioxidant, anti-inflammatory and antimicrobial activity of its leaf extracts.[11]
Preparations
Seed powder or extract studied for glycaemic and psychiatric-symptom support in clinical and preclinical work.

Dosage
Not documented
Sorrel is best treated as an occasional food rather than a daily medicinal herb, given its oxalate content; traditional infusions use roughly 2-4 g dried leaf per cup, taken occasionally rather than regularly. Educational reference only, not a prescription; avoid large or frequent amounts if prone to kidney stones or gout.
