## Overview

Great Burdock (Arctium lappa) contains the [prebiotic](/ingredients/condition/gut-health) inulin and the lignan arctigenin as primary bioactive compounds, which drive its anti-inflammatory and metabolic effects. Arctigenin inhibits NF-κB signaling and suppresses [pro-inflammatory cytokine](/ingredients/condition/inflammation) production, while inulin modulates gut microbiota composition to support lipid [metabolism](/ingredients/condition/weight-management).

## Health Benefits

• May reduce [inflammatory](/ingredients/condition/inflammation) markers in knee osteoarthritis patients, as observed in a small clinical trial (n=36). • Improved blood lipid profiles and [blood pressure](/ingredients/condition/heart-health) in osteoarthritis patients, based on a study design lacking specific randomization details. • Potential reduction in acne symptoms, though evidence is limited to a small uncontrolled study. • Offers [antioxidant](/ingredients/condition/antioxidant) properties due to its high polyphenol content, as noted in preclinical studies. • Traditional use suggests benefits for skin conditions like eczema and acne, though clinical evidence is lacking.

## Mechanism of Action

Arctigenin, a dibenzylbutyrolactone lignan in Arctium lappa, inhibits the NF-κB transcription factor pathway by blocking IκB kinase (IKK) phosphorylation, reducing downstream production of TNF-α, IL-1β, and IL-6. Chlorogenic acid and caffeic acid derivatives present in the root scavenge [reactive oxygen species](/ingredients/condition/antioxidant) and inhibit cyclooxygenase-2 (COX-2) enzyme activity, contributing to the [anti-inflammatory](/ingredients/condition/inflammation) effect. Inulin-type fructooligosaccharides act as prebiotics that selectively stimulate Bifidobacterium and Lactobacillus species, improving [gut barrier](/ingredients/condition/gut-health) integrity and modulating lipopolysaccharide-driven systemic inflammation.

## Clinical Summary

A small randomized clinical trial (n=36) in knee osteoarthritis patients found that burdock root tea supplementation significantly reduced serum levels of the inflammatory marker high-sensitivity C-reactive protein (hs-CRP) compared to baseline. A separate study in osteoarthritis patients reported improvements in total cholesterol, LDL, and systolic [blood pressure](/ingredients/condition/heart-health) following burdock supplementation, though the study lacked rigorous randomization details, limiting the strength of conclusions. Preliminary clinical and observational data suggest a reduction in acne vulgaris severity, potentially linked to its anti-androgenic and [anti-inflammatory](/ingredients/condition/inflammation) properties, but large-scale randomized controlled trials are absent. Overall, the current clinical evidence base is small, with most trials underpowered, and findings should be considered preliminary pending replication in larger, well-controlled studies.

## Nutritional Profile

Great Burdock root (Arctium lappa) per 100g fresh weight: Carbohydrates ~17.3g (primarily inulin-type fructooligosaccharides, comprising 3.5–4.3g inulin acting as prebiotic fiber); Total dietary fiber ~3.3g; Protein ~1.5g (containing essential amino acids including arginine and aspartic acid); Fat ~0.1g; Calories ~72 kcal. Key micronutrients: Potassium ~308mg (8.7% DV), Magnesium ~38mg (9% DV), Phosphorus ~51mg (5% DV), Calcium ~41mg (4% DV), Iron ~0.8mg (4.4% DV), Manganese ~0.23mg (10% DV), Folate ~23mcg (5.7% DV), Vitamin B6 ~0.24mg (14% DV), Vitamin C ~3.1mg (3.4% DV). Bioactive compounds: Arctiin (lignan glycoside) 0.5–2.3mg/g dry weight, converted by gut microbiota to arctigenin (bioavailability enhanced by intestinal flora); Chlorogenic acid ~12–35mg/100g (polyphenol, moderate bioavailability); Caffeic acid ~5–18mg/100g; Quercetin ~1.5–4mg/100g; Luteolin ~0.8–2.5mg/100g; Inulin (prebiotic fructan) varies by harvest season, higher in autumn (~up to 45% dry weight in root); Sesquiterpene lactones including tomentosin detectable in leaf extracts. Seeds contain ~15–30% fixed oils rich in arctiin. Bioavailability notes: Arctigenin from arctiin conversion is highly dependent on [gut microbiome](/ingredients/condition/gut-health) composition; inulin fermentation in colon produces short-chain fatty acids (butyrate, propionate); polyphenol absorption is moderate and enhanced when consumed with dietary fat.

## Dosage & Preparation

Clinically studied dosage includes 2g of burdock root steeped in 150ml of boiled water as tea, consumed 3 times daily (total 6g/day) for 6 weeks. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Burdock root is generally considered safe at typical dietary and supplemental doses, but allergic reactions including contact dermatitis are documented, particularly in individuals sensitive to Asteraceae/Compositae family plants such as ragweed, chrysanthemums, or daisies. It may potentiate anticoagulant medications such as warfarin due to coumarin-like constituents, increasing bleeding risk, and may have additive hypoglycemic effects when combined with insulin or oral antidiabetic drugs. Burdock root is contraindicated in pregnancy due to potential uterine stimulant effects observed in animal models, and safety during breastfeeding has not been established. Contamination of commercial burdock products with belladonna alkaloids has been reported historically, so sourcing from verified, third-party-tested suppliers is strongly advised.

## Scientific Research

Clinical evidence is limited, with one small trial (n=36) showing reduced [inflammatory](/ingredients/condition/inflammation) markers in osteoarthritis patients consuming burdock root tea. No RCTs or meta-analyses with PubMed PMIDs were identified; most evidence is preclinical or based on traditional reviews.

## Historical & Cultural Context

In Traditional Chinese Medicine, burdock roots have been used for centuries to 'detoxify' blood and promote [skin health](/ingredients/condition/skin-health). Across Europe, North America, and Asia, it has been employed as a blood purifier and remedy for various skin issues.

## Frequently Asked Questions

### What is burdock root used for in traditional medicine?

In European and East Asian traditional medicine, burdock root has been used primarily as a 'blood purifier' to treat skin conditions like acne and eczema, as well as to support liver function and reduce joint inflammation. Its use is rooted in centuries of practice across traditions including Traditional Chinese Medicine (TCM), where it is known as Niubang, and European herbalism dating back to medieval times.

### How much burdock root should I take per day?

Clinical studies on burdock root have used doses ranging from approximately 6 grams of dried root per day administered as a tea to standardized extract doses of 200–400 mg daily, though no universally agreed-upon therapeutic dose has been established. Most commercial supplements provide 300–500 mg of root extract per capsule, and users are advised to follow manufacturer guidelines and consult a healthcare provider, as optimal dosing depends on the form and indication.

### Does burdock root lower blood sugar?

Preclinical studies show that inulin and chlorogenic acid in burdock root can improve insulin sensitivity and reduce fasting blood glucose in diabetic animal models by enhancing GLUT4 translocation and inhibiting intestinal glucose absorption. However, robust human clinical trial data specifically confirming blood sugar lowering effects at supplemental doses is currently lacking, and individuals on antidiabetic medications should exercise caution due to potential additive hypoglycemic effects.

### Is burdock root safe to take with warfarin or blood thinners?

Burdock root contains coumarin-like compounds that may have additive anticoagulant effects when combined with warfarin (Coumadin) or other blood-thinning medications, potentially increasing the risk of excessive bleeding. Patients on anticoagulant or antiplatelet therapy such as aspirin, clopidogrel, or heparin should consult their physician before using burdock supplements and may require closer INR monitoring if use is continued.

### Can burdock root help with acne?

Burdock root's potential benefit for acne is attributed to arctigenin's inhibition of COX-2 and NF-κB-driven skin inflammation, as well as mild anti-androgenic activity that may reduce sebum production driven by dihydrotestosterone (DHT). Preliminary clinical observations suggest symptom improvement in acne patients, but these findings come from small, uncontrolled studies, meaning higher-quality randomized trials are needed before burdock can be formally recommended as an acne treatment.

### What is the most bioavailable form of burdock root—fresh, dried, extract, or powder?

Standardized extracts and decoctions (simmered tea) from dried burdock root are traditionally considered most bioavailable, as heat processing can enhance the availability of active compounds like inulin and phenolic acids. Powdered forms mixed into liquids or capsules offer convenience, though whole fresh root provides the full spectrum of fiber and nutrients. The choice depends on whether you prioritize absorption of specific compounds versus total dietary fiber content.

### Is burdock root safe to take during pregnancy and breastfeeding?

Burdock root is generally recognized as a food in many cultures and is considered safe in culinary amounts during pregnancy, though clinical safety data is limited. However, concentrated supplements or extracts are not well-studied in pregnant or nursing women, and some traditional sources suggest avoiding high doses due to potential uterine stimulant properties. Pregnant or breastfeeding individuals should consult a healthcare provider before taking burdock supplements.

### How strong is the clinical evidence for burdock root's effects on osteoarthritis and inflammation?

Current evidence comes from small, preliminary clinical trials (typically n=36 or fewer) showing reductions in inflammatory markers and improvements in blood lipids in osteoarthritis patients, but these studies often lack rigorous randomization and blinding. While results are promising, the limited sample sizes and methodological gaps mean larger, well-controlled trials are needed to confirm efficacy. Burdock root should be considered a supportive complement rather than a primary treatment for osteoarthritis based on current evidence.
