Key Constituents
Burdock root is a rich source of prebiotic inulin-type fructans (fructooligosaccharides) along with chlorogenic and caffeic acids, the lignans arctiin and arctigenin, cynarine and quercetin, which underlie its antioxidant, anti-inflammatory and gut-supporting activity.
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
Burdock (Arctium lappa) extracts and the lignan arctigenin inhibit proliferation and induce apoptosis in colon, breast, lung and gastric cancer cells, attenuate melanoma progression and reduce preneoplastic colon lesions in vivo (preclinical).
Traditional & Indicated Uses
inferred from anti-inflammatory action
inferred from digestive action
Arctium lappa root reduces diet-induced preneoplastic colon lesions and suppresses melanoma progression; its lignan arctigenin induces apoptosis in colon (HT-29), breast (in vitro/in vivo), lung and gastric cancer cells and chemosensitizes them to doxorubicin (preclinical).

Safety, Cautions & Contraindications
Generally safe as a food plant. Allergic reactions are possible in those sensitive to Asteraceae. Avoid in pregnancy due to uterine-stimulating effects reported in animal studies. The burs (seed heads) can cause mechanical irritation of skin and eyes on contact. Not recommended in biliary obstruction.
Duke (2002) rates burdock as +++ and notes antibacterial, antimutagenic, antitumor, choleretic, diuretic, and prebiotic (bifidogenic) activities at the experimental level (score 1). The root is rich in inulin (a prebiotic fructooligosaccharide), which promotes growth of beneficial intestinal bacteria. Dose: 1–2 g dried root in tea three times daily, or 2–4 ml of tincture. Duke notes burdock's general safety, though it belongs to the Asteraceae family and can trigger reactions in sensitive individuals. It should be distinguished from belladonna and similar plants, which resemble it in early growth (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
Robust biennial herb forming a large rosette of huge, heart-shaped (rhubarb-like), long-stalked leaves, dark green above and whitish-woolly beneath, in its first year. In the second year it sends up a tall, branching, grooved flowering stem bearing purple thistle-like flower heads enclosed in a globe of stiff, hooked bracts that ripen into the familiar clinging burrs.[1, 2]
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 disturbed ground, waste places, roadsides, field margins and riverbanks on rich, moist soils; native to Europe and temperate Asia and naturalised in North America and elsewhere.[2]
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 (autumn) or early in the second spring, before the flowering stem develops, when it is at its most tender and richest in inulin; leaves are picked through the first year, and the seed/fruit is collected from the dried burrs in the second autumn. Careful identification against deadly nightshade, whose root can resemble burdock, is essential before digging.[11]
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]
Preparations
Dried or fresh root simmered in water as a traditional alterative and digestive decoction.
Tincture of the dried root, ethanol 45% V/V or 25% V/V, 8-12 ml three times daily per the EU herbal monograph. The monograph states the ethanol strength but no drug-extract ratio, so no 1:5 ratio is claimed here. Educational reference only, not a prescription.
Fresh root peeled and cooked as a root vegetable (gobo), continuing the traditional food-medicine use.
Dosage
The EU herbal monograph on Arctium lappa L., radix gives, for adults and elderly, a single dose of 2-6 g of the comminuted root as an infusion, 3 times daily; a powdered herbal substance at 350 mg 3-5 times daily, a liquid extract at 2-8 mL 3 times daily and a soft extract at 0.2 g per dose (1-2 g daily) are also listed. Not recommended under 18 years, and a practitioner should be consulted if symptoms persist beyond 2 weeks. Educational reference only, not a prescription.
The EU herbal monograph gives 8-12 mL three times daily, for tinctures in either 45% V/V or 25% V/V ethanol, in adults and elderly. Educational reference only, not a prescription.
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.
