Dwarf Larkspur and Other Larkspurs (Delphinium tricorne Michx. and other species)


Clinical signs

Symptoms of larkspur poisoning vary according to the amount eaten and the animal's tolerance of the poison. Small amounts may cause loss of appetite, excitability, staggering, or muscular incoordination, and constipation. Severe symptoms include slobbering, nausea, vomiting, colic, bloating, and convulsive movements. Fatal poisoning brings convulsions and paralysis of the respiratory system. Autopsies reveal inflammation, or at least congestion of the windpipe, stomach and small intestine, congestion of the superficial blood vessels, and dark, extremely congested kidneys.
