Key Constituents
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.
Eugenol typically makes up the great majority of clove oil and is responsible for most of its analgesic, antimicrobial and anti-inflammatory activity.

Safety, Cautions & Contraindications
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).
Strong and concentrated: Clove oil is very potent and should always be diluted before skin or mouth use.Dental use: Undiluted clove oil can burn gums or skin.Blood thinning: Clove may increase bleeding risk in large amounts or with anticoagulants.Pregnancy: Culinary amounts are fine; medicinal doses should be used cautiously.Children: Essential oil should be used with extra caution and diluted well.
Duke (2002) rates cloves as +++ with clinical evidence (score 2) for analgesic activity — specifically, topical application of clove oil (eugenol) for dental pain is clinically validated. The plant also shows strong antimicrobial, antifungal (anti-Candida), antispasmodic, and antiviral activities at the experimental level. Commission E approves topical clove preparations for dental pain. Recommended dose: 1–5% clove oil preparation (topical) or 150 mg clove powder internally. The essential oil is irritating to mucous membranes and should not be applied undiluted to skin or mucous membranes (Duke, 2002).

Botanical Description
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]
Evergreen tree (Myrtaceae), 8-12 m tall (occasionally to 20 m), with a pyramidal crown. Leaves are glossy, elliptical and aromatic. Small crimson flowers are borne in terminal clusters; the unopened flower buds, picked before they open and dried, are the 'cloves' of commerce and the medicinal/culinary part used.[2]
Habitat
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]
Native to the Maluku Islands (Moluccas, the historic 'Spice Islands') of Indonesia, now cultivated throughout the tropics, notably Zanzibar, Madagascar, Sri Lanka and Indonesia, in warm, humid, well-drained tropical conditions.[2]
Harvesting
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]
Unopened flower buds are hand-picked while still green-pink, just before they would open, then sun-dried until they turn dark reddish-brown - the familiar clove spice.[2]
Traditional Uses
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]
Clove has an ancient trade history and a long traditional use across Asian, African and European medicine as a dental analgesic (chewed or applied as oil for toothache), a digestive carminative, and an antiseptic. Modern research on its principal constituent eugenol supports strong analgesic, antimicrobial, antioxidant and anti-inflammatory activity, with clove oil remaining a recognised topical dental-pain remedy.[2]
Preparations
Dosage
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.
