Scientific Name: Delphinium species
Family: Ranunculaceae
Toxicity: Toxic to Dogs, Toxic to Cats, Toxic to Horses
Toxic Principles: Diterpene alkaloids
Clinical Signs: Unless there is a lack of suitable forage, horses typically do not consume toxic amounts of larkspur. The toxicity of the plant may vary depending on seasonal changes and field conditions; as the plant matures, it generally becomes less toxic. The alkaloids in the plant cause neuromuscular paralysis; clinical effects include constipation, colic, increased salivation, muscle tremors, stiffness, weakness, recumbency, and convulsions. Cardiac failure may occur, as can death from respiratory paralysis.
