Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
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.
The main anti-inflammatory principles; also responsible for the plant's toxicity and contact-allergy potential.
Aromatic and supporting constituents of the flower.
Present in small amounts; relevant to the caution against internal use.
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).
Topical anti-inflammatory for bruising, swelling and sprains
Helenalin, the sesquiterpene lactone of Arnica montana, shows anticancer activity against multiple tumour types in vitro and in vivo, largely by covalently inhibiting NF-kappaB p65 and inducing apoptosis (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).

inferred from anti-inflammatory action
Antiecchymotic / vulnerary (helps disperse bruises); Topical anti-inflammatory for bruising, swelling and sprains
Arnica montana and its constituent helenalin exert anticancer activity against several tumour types in vitro and in vivo, inhibiting NF-kappaB (p65) signalling, inducing apoptosis and synergizing with other anticancer agents (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).
EXTERNAL USE ONLY on unbroken skin. Arnica is toxic if swallowed and can cause stomach pain, vomiting, diarrhoea, breathing difficulty, irregular heartbeat and, in serious cases, cardiac arrest; the only safe oral form is the highly diluted homeopathic preparation.
Do not apply to broken or damaged skin, open wounds, eyes or mucous membranes.
As a member of the daisy family (Asteraceae) it can cause allergic contact dermatitis; prolonged topical use can also irritate the skin.
External Ids
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]
Aromatic mountain perennial herb with a basal rosette of oval, hairy leaves and one or two pairs of smaller opposite leaves on an erect, softly hairy flowering stem. Each stem bears one or a few large, bright golden-yellow, daisy-like flower heads with narrow, slightly twisted ray florets.[4]
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 in acidic, nutrient-poor mountain meadows, pastures and open woodland, typically at moderate to high elevations across central and northern Europe; increasingly scarce in the wild due to habitat loss and overharvesting.[4]
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 flower heads are picked by hand as they open, in mid- to late summer, and dried quickly in a warm, shaded, airy place; wild populations are protected in many regions, so cultivated or sustainably wildcrafted material is preferred.[4]
Traditional Uses
Arnica flower has a long central European folk reputation, reflected in the name 'leopard's bane' and 'mountain tobacco', as a topical remedy for bruising, sprains, muscle soreness and swelling after minor injury, applied only to unbroken skin. Internal use of the whole herb has always been considered dangerous and is confined to highly diluted homeopathic preparations.[4]
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.
Standardised flower extract formulated into a cream, gel or ointment for external application to bruises, sprains and muscle soreness on unbroken skin.
Alcoholic tincture of the dried flower heads, diluted before topical application as a compress; never taken internally in this form.
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.
The EU herbal monograph gives cutaneous use only, in adolescents, adults and elderly - a semi-solid preparation containing 20-25% tincture applied as a thin layer 2-3 times daily, a 50% liquid-extract preparation 2-4 times daily, or 2.5 mL of a liquid preparation as an impregnated dressing 3-4 times daily. Apply to unbroken skin only. If symptoms persist after 3 to 4 days a healthcare practitioner should be consulted. Not recommended under 12 years. Never taken by mouth except as a highly diluted homeopathic preparation. Educational reference only, not a prescription.
