Larkspur
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.
If you suspect your pet may have ingested a potentially toxic substance, call the APCC at (888) 426-4435 or contact your local veterinarian as soon as possible.*
