Family: Asteraceae Part used: root, seed, leaf Arctium lappa L. is a robust biennial, found throughout Europe on roadsides, verges and scrub land. The Flora of Turkey gives three Arctium species, not including Arctium lappa but including Arctium minus. Stout, downy, striated, branched stems (to 1 m) bear alternate, entire leaves which are large (to 50 cm long) and wide with a heart-shaped base and white down underneath. The petioles (leaf-stalks) are solid. The spherical, purple flowerheads are stalked and surrounded by dense clusters of scale-like hooked bracts. The egg-shaped seeds are achenes and surrounded by a pappus of yellowish free hairs and characteristic stiff hooked scales derived from the bracts. The ribbed seeds are dispersed by animals as the scales stick firmly to fur. Lesser burdock Arctium minus Bernh. is very similar but smaller (to 50 cm). Basal leaves are smaller and narrower with hollow leaf stalks. The purple flowerheads occur in clusters and project beyond the surrounding spiny bracts. The seed is not ribbed. Arctium minus has three subspecies and a fertile cross with Arctium lappa and there are many variants. The photographed specimen may be a cross as it as over 1 m tall but had hollow Read more […]

These authors show that the concept of an alterative action for greater burdock can be traced back as far as Quincy, but the plant was known to the Ancients, so what does Culpeper have to report on its medicinal virtues if the term ‘alterative’ was unknown to him? Actually, Culpeper does write of cleansing medicines. In his Key to Galen and Hypocrates, their Method of Physic (1669) he contrasts the more gentle Greek ‘rhytics’ (actually misspelled from the Greek ‘rhyptikos’) for external use with the internally administered cathartics. These topical cleansers are of an earthy quality, although they may be hot or cold, and sweet, salty or bitter to the taste. Taken orally, the cathartics purge certain humours from the body as they themselves are voided. Similarly, when applied topically, the rhyptics cleanse foul ulcers by carrying away discharge or thick matter as they themselves are removed. Culpeper distinguishes this cleansing action from the effect of topical discussive medicines which, by their heat when laid on, attempt to thin and disperse an aggregation of matter such as fluid or blood. Other cleansing medicines are designed to remove damaged flesh to facilitate healing. Before the application of cleansing medicines, Read more […]
When we turn to modern sources, we may imagine that the internal use of burdock for boils echoes the old topical use. However, an antimicrobial action would be desirable to support this action, and this has been linked to poly-acetylenes found in fresh burdock root, whereas the classical authors wanted the leaves to be applied topically. Weiss considers the root the most important part of the plant for medicinal use but does not consider its action to be very great and recommends its use only in combination with other herbs. This could include cystitis, as listed by other authors. An oil made from the root can be used, says Weiss, to stimulate hair growth in alopecia and for dry seborrhoea. Mills and Bone also discuss only the root. Wood and Menzies-Trull include the seeds as well, perhaps following the recommendation by Priest & Priest of the seeds, especially in skin conditions. Pelikan highlights the fact that it is only the flower heads of burdock, and its fruit or seed, which display the thistle aspect of the plant. The leaves and root, on the other hand, are rich in mucilage, which he regards as evidence of their ‘struggle against spiny hardness’. Here we have an image to link with the several recommendations Read more […]
