Background
Chrysanthemum cinerariaefolium is a compositae plant that grows on rocky ground in Europe, Australia, Japan, and North America. It is a tufted perennial with silvery-grey silky leaves and a solitary 3 to 4 cm white flower. It is the main source of the pyrethrum insecticides which are still used for organic gardening. The pyrethrins (i.e., permethrin) have insecticide activity are prepared synthetically and are chemically unrelated to pyrethrum.
The principle allergen is the sesquiterpene lactone, pyrethrosin.
