This is a reference that includes plant images, pictures of affected animals and presentations concerning the botany, chemistry, toxicology, diagnosis and prevention of poisoning of animals by plants and other natural flora (fungi, etc.). The information presented here is NOT a complete database of all plants that are poisonous, but attempts to cover many of the plants that grow in the U.S. that may be poisonous to livestock. While some information is presented about plants poisonous to pets and humans, this is not intended to be a comprehensive resource.
The Poisonous Plant Guide is constructed to enable location of a plant by either knowing the common or botanical name of the plant. Alternatively if the plant is not known, but the disease symptom is, it is possible to search by the presenting clinical sign e.g.: Abortion, Sudden death, photosensitization.
