Historical Background

Burdock has been a staple of European 'alterative' (blood-purifying) traditions and East Asian medicine for centuries, its root simmered as a nourishing decoction and its prickly burrs reputed to have inspired the hook-and-loop fastener. In Japan the root (gobo) is eaten as food and tea.

Earliest recorded uses: European and East Asian (TCM, where the seed niubangzi is used) medicine for centuries; a traditional 'blood cleanser.'

Tea Information

Research Summary

Burdock has a long tradition as an 'alterative' and skin herb, and its root is a nutritious food. Clinical evidence for its traditional uses is insufficient; preclinical work suggests anti-inflammatory and prebiotic effects. It is not a treatment for skin disease or any condition.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
