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).
Improves glycemic control in type 2 diabetes - lowers fasting blood glucose and HbA1c
Anti-inflammatory and antioxidant; Hepatoprotective / liver support (protects liver cells, antioxidant and antifibrotic)
Digestive support / mild dyspepsia (traditional)
Hepatoprotective / liver support (protects liver cells, antioxidant and antifibrotic); May improve liver enzymes and hepatic fat in non-alcoholic fatty liver disease (NAFLD); Supports liver recovery and 'detox' (traditional framing of the hepatoprotective action)
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).
Very well tolerated, even at high doses; the main effects are mild gastrointestinal upset (nausea, loose stools). As a member of the daisy family (Asteraceae), it can cause allergic reactions in sensitive people.
Has a low potential for drug interactions (little effect on liver CYP enzymes), but use caution with medicines that have a narrow therapeutic window. Human pregnancy data are limited, so use cautiously.

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]
Robust biennial (occasionally annual) thistle (Asteraceae), 30-150 cm tall. Leaves are glossy dark green with distinctive white marbled veining (the 'milk' of legend), spiny-margined and deeply lobed. Large, solitary, purple-pink thistle-type flower heads are surrounded by spiny bracts, followed by shiny, mottled brown-black seeds - the part used.[12]
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 to the Mediterranean region, now naturalised worldwide on disturbed, sunny ground - roadsides, waste places and dry pastures - and widely cultivated commercially for its seed.[12]
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]
Seed heads are harvested once fully dry (late summer), and the seeds (fruit) are threshed out.[12]
Traditional Uses
Milk thistle has a very long European folk-medicine tradition, documented since antiquity, as a liver tonic, and its seed extract, standardised to the flavonolignan complex silymarin, is one of the most extensively studied herbal hepatoprotectants. Modern research supports antioxidant, anti-inflammatory and liver-protective activity, with growing interest in metabolic/blood-sugar effects.[12, 13]
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.
