Bloodroot (Sanguinaria canadensis) is a stemless perennial herb which is native to eastern and central North America. Bloodroot grows throughout the mid to eastern states of the United States, east of the Mississippi and from southern Canada to the northern half of Louisiana and Georgia. It is found in most counties of Illinois in moist but well-drained woodland soil.

All parts of the plant are poisonous, containing isoquinoline alkaloids. The toxins are most highly concentrated in the root, after leaves have opened.

Although most poisoning cases have been reported in goats, horses are susceptible to the toxic effects of isoquinoline alkaloids as well.
