The Bordeles School of Le Coulant described in 1966, a contact dermatitis produced by "hepatics" of the Frullania genus. The hepatics together with the mosses and sphagnus form the group of Bryophytes. Only the hepatics with leaves or Jungermaniales have a capacity to cause sensitivity. They grow in
Contact sensitivity to plants containing 1 or more sesquiterpene lactones (SLs) is difficult to diagnose. The mixture of SLs (SL mix) has been shown to detect only about 60% of sensitized individuals. In order to improve the diagnosis of sensitization to plants containing SLs, we have tested a
9 cases of contact sensitivity to Dittrichia viscosa, mainly with an airborne pattern, are described. All patients reacted to the fresh leaf of the plant and to its ethereal extracts at 1 and 0.5% pet., and some of them also to that at 0.1% pet. Positive reactions to Frullania dilatata, Laurus
7 subjects, each giving a history of scaly or vesicular dermatitis in light-exposed areas after going for strolls to the park, the forest or the country during warm weather, were evaluated. Patch testing was carried out with Frullania dilatata and Frullania tamarisci as well as with 2 common members
Contact dermatitis from frullania mainly affects people living in the country. The 2 most frequent species in Europe, Frullania dilatata and Frullania tamarisci, do not cross-react: both species must be patch tested when frullania intolerance is suspected. Yet patch testing with frullania may be
