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.
Anti-inflammatory constituents; harpagoside also has cardiac (inotropic) activity.
Supporting antioxidant constituents.
Pharmacological Actions
Mild diuretic and lymphatic 'detoxifying' herb (traditional); Traditional 'alterative' for chronic skin conditions - eczema, psoriasis, rashes (as a poultice, salve or tea)

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).
Avoid if you have a heart condition or take cardiac medicines: figwort's harpagoside has a stimulating (inotropic) effect on the heart, so it is traditionally avoided with rapid heartbeat or heart disease.
Avoid during pregnancy. There is insufficient reliable evidence on the safety of taking figwort by mouth, so internal use should be cautious and short-term.
External Ids
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]
Tall perennial herb (Scrophulariaceae), 50-100 cm (occasionally more), with a distinctly square stem. Leaves are opposite, ovate, toothed and unpleasant-smelling. Small, dull maroon-brown, two-lipped flowers are borne in loose, branched clusters (cymes), followed by small dry seed capsules.[11]
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 Europe and western Asia, growing in damp woods, hedge banks, ditches and shady waste ground on moist, nutrient-rich soils.[11]
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]
Aerial parts are cut during flowering (summer); the root can also be dug in autumn.[11]
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]
Figwort takes one common name, 'scrofula plant', from its historic traditional use for scrofula (tuberculous lymph-node swelling) under the Doctrine of Signatures, its knotty root resembling swollen glands. It has a long folk-medicine reputation as an 'alterative' (blood-purifying) herb for chronic skin conditions such as eczema and psoriasis, applied as a poultice, salve or tea.[11, 12]
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.
Traditional guidance suggests roughly 2-4 g dried herb per cup as an infusion, taken cautiously and short-term given limited safety data and the cardioactive harpagoside content. Educational reference only, not a prescription; avoid with heart conditions/cardiac medicines and in pregnancy.
