Key Constituents
The major storage carbohydrate; a prebiotic fibre.
Anti-inflammatory and antioxidant constituents.
Antimicrobial and antioxidant 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.
Pharmacological Actions
Traditional 'alterative' / depurative for chronic skin conditions - eczema, psoriasis, acne and boils (internally and topically)
Lesser burdock (Arctium minus) leaf, flower and root extracts (rich in arctiin/arctigenin and chlorogenic acid) are cytotoxic to breast and liver cancer cells, including multidrug-resistant tumour lines (preclinical).
Traditional & Indicated Uses
Sebaceous-gland regulator - helps balance skin oil (acne); Traditional 'alterative' / depurative for chronic skin conditions - eczema, psoriasis, acne and boils (internally and topically)
inferred from anti-inflammatory action
Arctium minus extracts show dose-dependent cytotoxicity against MCF-7 and MDA-MB-231 breast cancer and HepG2 liver cancer cells and are active against both sensitive and multidrug-resistant tumour cell lines (preclinical).
Mild diuretic supporting elimination ('detox', traditional); Traditional 'alterative' / depurative for chronic skin conditions - eczema, psoriasis, acne and boils (internally and topically)

Safety, Cautions & Contraindications
As a member of the daisy family (Asteraceae), it can cause allergic reactions in people sensitive to ragweed and related plants. The high inulin content can cause temporary bloating or gas.
May lower blood sugar (caution with antidiabetic medicines) and add to diuretics; avoid medicinal doses in pregnancy.
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
Biennial herb closely related to greater burdock, forming a first-year rosette of large, heart-shaped, long-stalked leaves, green above and grey-woolly beneath, generally smaller than Arctium lappa. In the second year it produces a branching flowering stem with smaller purple thistle-like flower heads in a looser, more sprawling habit, each enclosed in a globe of hooked bracts that ripen into clinging burrs.[15]
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
A common weed of waste ground, roadsides, hedgerows and disturbed soil; native to Europe and widely naturalised in North America, where it is often the most common wild burdock species.[15]
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
The root is dug at the end of the first growing season or early in the second spring, before flowering; leaf may be gathered through the first year. Careful identification against deadly nightshade, whose root can resemble burdock, is essential before digging.[15]
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
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]

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.
