Burdock Overview

The burdock plant is a herbaceous plant that grows to about 1-2.7 m in height. The thick hairy stems grow reddish-purple tubular flowers, which later develop into brownish-grey, wrinkled seed-heads or burrs with hooked spines. Close to its harvesting time, a deep taproot grows to about 60-90 cm in length and features a slender brownish carrot-shaped root. The root is very crisp and has a sweet, mild, and pungent flavour with a little muddy harshness that can be reduced. Burdock leaves, which are less used than the root, are collected in winter and have a somewhat bitter taste. Uses: Culinary and traditional medicine.
