antioxidant and anti-inflammatory support
Biomarker supportBurdock lignans (arctigenin, arctiin) and polyphenols show antioxidant and anti-inflammatory activity in laboratory and animal studies. Some preliminary human work has looked at inflammatory markers, but evidence is sparse and does not establish a clinical benefit.
Bottom line: Antioxidant activity is demonstrated mainly in the lab, not as a proven human health effect.

Frequently asked questions
Is burdock root the same as gobo?⌄
Yes. Gobo is the Japanese name for burdock root, which is widely used as a vegetable in Japanese, Korean, and Taiwanese cuisines.
Can burdock really clear up acne?⌄
Traditional use as a 'blood purifier' for skin conditions has limited modern clinical evidence. Some users report improvement, possibly through anti-inflammatory effects, but burdock is not a substitute for evaluated dermatologic care for moderate to severe acne.
Is burdock safe to eat regularly?⌄
Yes. Burdock has been eaten as a food in East Asia for centuries with no significant safety concerns. Choose reputable products for medicinal preparations due to historical contamination concerns in some commercial herbal teas.
Does burdock interact with diabetes medications?⌄
Possibly. Burdock may have mild blood-glucose-lowering effects. Monitor blood glucose if you take insulin or oral diabetes medications and use burdock supplements regularly.
Can I be allergic to burdock?⌄
Yes, especially if you are allergic to other Asteraceae plants like ragweed, chrysanthemum, or daisies. Cross-reactivity is possible.
