Dandelion dermatitis

Abstract

7 subjects, each giving a history suggesting dandelion dermatitis, were patch tested with extracts of dandelion as well as with other common members of the Compositae and to the sesquiterpene-lactone-mix. All were positive to dandelion extracts but only 2 reacted to the sesquiterpene-lactone-mix. Although the mix is a useful screening test for chrysanthemum dermatitis, it may miss dandelion allergy.
