maculantum is an alkaloid content that act as a poisonous plant .it also called
death of Socrates”OR”cup of hemlock”.two types of compound are effective in
this species that’s compound are (polyenes and furanocoumarins) 24.

maculantum have two genera (cicuta and oenanthe).they are most poisonous in United
Kingdom. A small amount of plant ingestion may cause CNS stimulatory effects
including seizures that in the absence of aggressive supportive care can result
in death. Some other features may also
included nausea, vomiting, diarrhea, tachycardia, mydriasis, rhabdomyolysis,
renal failure, coma, respiratory impairment, and cardiac dysrhythmias.
So poisoning occurs due to water hemlock 25.
