It is well known to little boys who pull off the clinging seed vessels to throw at one another, it is also known as Personata, Happy-major, and Clot-bur. A traditional herbal medicine, burdock was formerly listed in the British Pharmaceutical Codex and is widely recorded in most writings on medicinal herbs. This tall, branching biennial has large, rounded to arrow-shaped leaves and purple flower heads encased in bracts with hooked tips. Burdock can be an invasive weed. Harvest roots after the 1st years growing season, before it goes to seed in its second year. The plant varies considerably in appearance, and by some botanists various subspecies, or even separate species, have been described, the variations being according to the size of the flower-heads and of the whole plant, the abundance of the whitish cottonlike substance that is sometimes found on the involucres, or the absence of it, the length of the flower-stalks, etc.

 Arctium lappa L:leaves and flower The flower-heads are found expanded during the latter part of the summer and well into the autumn: all the florets are tubular, the stamens are dark purple and the styles are whitish. The plant owes its dissemination greatly to the little-hooked prickles of its involucre, which adhere to everything with which they come in contact, and by attaching themselves to coats of animals are often carried to a distance. The dried root from plants of the first year's growth forms the herb, but the leaves and fruits (commonly, though erroneously, called seeds) are also used.

As a rule they are 30 cm (12 inches) or more in length and about 2.5 cm (1 inch) thick, sometimes, however, they extend 60~90 cm (2 to 3 feet), making it necessary to dig by hand.
