General poisoning notes:

Chrysanthemum (Chrysanthemum indicum) and cultivated hybrids (C. X morifolium Ramat.) are perennial ornamentals grown indoors and outdoors. Some humans develop contact dermatitis after extended exposure to garden chrysanthemums. This is an occupational hazard of florists, nursery workers, and gardeners. (Rook and Mitchell 1979, Frohne and Pfander 1983).

Notes on Toxic plant chemicals:

Arteglasin A is a sesquiterpene lactone of the quaianolide type and is one of the active allergens of garden chrysanthemums. A cross-link can form between this chemical and sulfhydryl groups of body proteins so that complete antigens are produced. Repeated exposure can cause the allergic reaction. Humans who are sensitive to one member of the Compositae family can become sensitive to other members of the plant family, such as yarrow (Achillea millefolium) or wild chamomile (Matricaria chamomilla)(Mitchell and Rook 1979; Frohne and Pfander 1983).
