The toxicity of coniine is similar in livestock and in people.

Water hemlock may reach a height of 2.5 meters and can also be confused with other plants such as wild carrot, also known as Queen Anne's lace (.Poison hemlock contains several piperidine alkaloid toxins (namely coniine) that are structurally similar to nicotine. Coniine, a plant piperidine alkaloid, comes from Spotted or Poison Hemlock (Conium maculatum). Death is typically from respiratory failure.Water hemlock contains cicutoxin, a potent, noncompetitive gamma-aminobutyric acid (GABA) receptor antagonist. In order to prevent future poisonings, become familiar with all of the plants within your home or on your property.

Symptoms of atropine poisoning: Mydriasis (dilation of … The general symptoms of hemlock poisoning are effects on nervous system (stimulation followed by paralysis of motor nerve endings and CNS stimulation and later depression), vomiting, trembling, problems in movement, slow and weak later rapid pulse, rapid respiration, salivation, urination, nausea, convulsions, coma and death.This site needs JavaScript to work properly. Chemical Abstract Service Registry Numbers: 458-88-8 and 3238-60-6,Synonyms: CASRN – 458-88-8: (+)-Coniine; (.Activation of nicotinic receptors at autonomic ganglia produces varied effects in the sympathetic and parasympathetic nervous system.
