Riddelliine: Found in some plants of the daisy family, common in the western United States, this compound is now listed as a “reasonably anticipated” carcinogen as a result of rodent studies that show it can cause leukemia, liver cancer, lung tumors, and cancer of the blood vessels. While no riddelliine-containing plants are used for food or commercial purposes in the United States, at least 13 species are used in herbal medicines, and may be consumed as food in other parts of the world. Exposure could also result from consuming animal products from species that feed on the plants.

Riddelliine belongs to a class of toxic pyrrolizidine alkaloids and is isolated from plants of the genera Crotalaria, Amsinckia, and Senecio that grow in the western United States.
