Botanical Description

A robust biennial 1-2 m tall with large broad heart-shaped rhubarb-like leaves, round purple thistle-like flower heads with hooked bracts that cling to fur, and a long tapering fleshy taproot.

Also known as: Gobo, Niubangzi, Beggar's Buttons

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.'

Modern Evidence

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.
