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 pungent alkaloid-like compounds responsible for the fruit's heat and its counterirritant/analgesic action via TRPV1 receptor desensitisation.
Give ripe red fruit its colour and contribute antioxidant and anti-inflammatory activity.
Antioxidant and anti-inflammatory flavonoids identified in leaf and fruit extracts.
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).
Capsaicin causes intense burning sensation; avoid contact with eyes and mucous membranes. High oral doses can cause gastrointestinal irritation, nausea, and diarrhoea. Topical preparations may cause skin irritation and should be used diluted. Not recommended for individuals with active peptic ulcers. Caution with anticoagulants — capsaicin may enhance bleeding risk. During pregnancy, culinary amounts are considered safe, but high-dose supplements should be avoided. Repeated topical application leads to desensitisation (TRPV1 depletion), which is the basis for its analgesic use. Children under 2 should not be given capsaicin-containing topical products (Basu and Bhattacharyya, 2023).
Duke (2002) rates cayenne/chili pepper (Capsicum annuum) highly for its clinically documented analgesic, counterirritant, and rubefacient activities. Commission E approves topical capsaicin preparations for muscle pain, arthritis, and neuralgia (score 2). The active compound capsaicin depletes substance P in sensory neurons upon repeated application, reducing pain signals. Capsaicin cream (0.025–0.075%) is a validated treatment for post-herpetic neuralgia, diabetic neuropathy, and osteoarthritis pain. Internal use can irritate mucous membranes; external use requires avoiding contact with eyes and mucous membranes (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]
Bushy annual or short-lived perennial herb (grown as an annual in temperate climates) with glossy, oval to lance-shaped leaves. Small, star-shaped, white to greenish flowers give way to the characteristic fleshy, hollow fruit (a berry), which ripens from green through yellow to red and varies enormously in size, shape and pungency between cultivars.[1]
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 Central and South America; cultivated worldwide in warm and temperate climates as a food and medicinal crop, thriving in full sun on well-drained soil.[1]
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]
Fruit is picked at the desired stage of ripeness (green for milder use, fully red for maximum capsaicin and carotenoid content) through summer and autumn; seeds are separated and dried from fully ripe fruit.
Traditional Uses
Chili pepper fruit has a long history across the Americas and, after global spread, in many other traditional medicine systems as a warming digestive stimulant and topical counterirritant/analgesic for muscle and joint pain, building on capsaicin's now well-documented ability to desensitise pain-sensing nerve fibres with repeated application.[1]
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 capsaicin cream or patch applied to the affected area for muscle, joint or nerve pain; repeated application depletes substance P and reduces pain signalling.
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 on Capsici fructus gives semi-solid dosage forms corresponding to 40-53 mg capsaicinoids per 100 g, applied as a thin layer to the affected area 2-4 times daily, in adults and elderly. For medicated plasters, a maximum of 1 plaster per day applied for at least 4 and up to 12 hours, with at least 12 hours before a new plaster is applied to the same area. Not recommended under 18 years. Expect an initial burning sensation that lessens with repeated use. Note the monograph covers hot chilli fruit (C. annuum var. minimum and small-fruited C. frutescens), not sweet peppers. Educational reference only, not a prescription.
