The irequent poisoning from eating the root of Cowbane (CicIda maeulata, L) are not infrequent in the state of Iowa and elsewhere. It affects man, cattle and horses. Every now and then, there are accounts of poisoning from “wild parsnips” in our papers. The writer has at various times received communications with specimens of “wild parsnips.” The subject is of considerable interest and especially so because the plant is widely distributed in Iowa and a large number of people are not aware of the poisonous nature of the root. Spotted Cowbane is a member of the Carrot family or as it is known botanically, Umbelliferae.
