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.
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).
Anti-inflammatory and antioxidant
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).
Traditional use only; clinical evidence is limited, so a persistent cough or digestive complaint needs medical assessment. Safety in pregnancy and breastfeeding is not established.

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]
Low, creeping, mat-forming perennial herb with softly hairy, oval, finely toothed leaves along trailing stems that root as they spread. Small, pale lilac-blue flowers with darker veining are borne in slender upright spikes rising from the leaf axils.[8]
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]
Grows on dry heath, moorland, open woodland, grassland and banks on acidic, well-drained soils; native to Europe and naturalised in North America.[8]
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]
The flowering aerial parts are cut in summer while in flower and dried in a warm, shaded, airy place; the closely related Veronica chamaedrys is a frequent adulterant, so careful identification (or a reputable source) is important.[8]
Traditional Uses
Speedwell has a long European folk history as a mild digestive tonic and traditional expectorant for cough and respiratory complaints, and has also been used topically as a soothing wash for irritated skin; modern research on its iridoid glycosides supports a molecular basis for the traditional respiratory use.
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.
