Toxic component and mechanism
The toxic component in Chrysanthemum is pyrethrins and sesquiterpene lactones.
What makes this plant different
Chrysanthemums are a natural source of pyrethrins, the same class of compound used in many flea and tick products — which means a pet with an existing pyrethrin sensitivity from topical flea treatments could theoretically react more strongly to the plant as well, though this hasn't been formally studied.
