We investigated the value of patch testing with dandelion (Compositae) extract in addition to sesquiterpene lactone (SL) mix in selected patients. After we detected a case of contact erythema multiforme after patch testing with dandelion and common chickweed (Caryophyllaceae), additional testing with common chickweed extract was performed. A total of 235 adults with a mean age of 52.3 years wer...

Common Names The English name dandelion is a corruption of the French dent de leon, meaning “lion’s tooth.” The herb is similarly named in many Indo-European tongues, also being called “lion’s tooth” in German (Löwenzahn) and Spanish (diente de leon). The name refers to the toothed margins of the leaves. In both modern French and English, the name for dandelion reflects its diuretic nature—bein...

In this paper we study the problem of shape from silhouette outlines (SFO) using a novel adaptive dandelion model. SFO reconstructs a 3D model using only the outmost silhouette contours and produces a solid called the ‘‘bounding hull’’. The dandelion model is composed of a pencil of organized line segments emitted from a common point which samples the bounding hull surface in regularly distribu...

We tested for ecological differences among apomictic dandelion genotypes in Vancouver, British Columbia, Canada, in order to establish a basis for predicting potential ecological consequences of genetic variation in invading populations. A greenhouse experiment on 30 potential clonal families revealed significant among-family variation for leaf morphological traits, and molecular analyses confi...

Ultraviolet (UV) irradiation causes damage in skin by generating excessive reactive oxygen species (ROS) and induction of matrix metalloproteinases (MMPs), leading to skin photoageing. Dandelion extracts have long been used for traditional Chinese medicine and native American medicine to treat cancers, hepatitis, and digestive diseases; however, less is known on the effects of dandelion extract...

A field experiment was conducted to observe the influence of a cover crop (winter wheat, Triticum aestivum L.), and a perennial weed (dandelion, Taraxacum officinale Weber ex Wigg.), on vesicular-arbuscular mycorrhiza (VAM) inoculum potential, soil aggregation, and maize yield after one season. Mycorrhizal colonization of maize roots was higher following the autumn planting of either winter whe...

Abstract Background Taraxacum officinale , or the common dandelion, is a widespread perennial species recognized worldwide as lawn and garden weed.
