Compositae patch test

A. millefolium contains sesquiterpene lactones, polyacetylenes, coumarins, and flavonoids. Extracts have often been used in cosmetics in concentrations of 0.5-10%. A. millefolium was weakly genotoxic in Drosophila mela-nogaster. In provocative testing, patients reacted to a mix of Compositae that contained yarrow, as well as to yarrow itself. In clinical use, a formulation containing a 0.1% extract was not a sensitizer and alcoholic extracts of the dried leaves and stalks of the flower were not phototoxic (6). However, positive patch tests to A. millefolium have been reported (7). [Pg.362]

Among 290 patients with eczema, patch testing with 5% Roman chamomile elicited a positive reaction in only one person (Meneghini et al. 1971). Patch testing with Roman chamomile in individuals with prior allergy to different Compositae plants indicated that 2 of 25 patients were allergic to Roman chamomile (Hausen 1979). A maximization...

Many instances of positive patch-test reactions to Frullania or frullanolide have been reported in patients sensitised to sesquiterpene lactones from plants in the family Compositae. Equally, forest workers who have become sensitised to liverworts may well exhibit crossreactions to plants in the families Compositae (Mitchell et al. 1970, 1971 Storrs et al. 1976 Fernandez de Corres and Corrales Torres 1978 Hausen and Osmund-sen 1983 Fernandez de Corres 1984 Gon alo 1987 Gon alo and Gon alo 1991 Lovell and Rowan 1991), Magnoliaceae (Fernandez de Corres and Corrales...
