| Comments |
"Sesquiterpene lactones are the allergens in chrysanthemums and other Compositae plants." Examples of these plants are broomweed, chamomile, chicory, cornflower, daisy, dandelion, feverfew, marigold, pyrethrum, ragweed, sunflower, thistle, and yarrow. Sesquiterpene lactones cause an acute or chronic dermatitis. Chronic dermatitis is more common, and it resembles a photodermatitis. Unlike a photodermatitis, the rash may involve the upper eyelids and the retroauricular and submental areas of the face. Florists and growers of chrysanthemums may present with rash of the fingers or hands. [Marks, p. 248-51] |
