Downsides (Poison Hemlock):
"Classed appropriately by the FDA as an unsafe herb containing the poisonous alkaloid coniine and other closely related alkaloids." Plant can also cause contact dermatosis. Ingestion may cause debility, drowsiness, nausea, labored respiration, paralysis, asphyxia, and death. Following lethal doses, animals rapidly begin to show symptoms; among them are paralysis of the tongue, mydriasis, head pressure, giddiness, nausea, vomiting, diarrhea, and collapse into central paralysis (first the feet and legs, then the buttocks, arms, then paralysis of the swallowing and speech). With increasing dyspnea and cyanosis, death ensues through central respiratory paralysis. Lethal dose is about 500 to 1000 mg coniine for man (CRC; HHB). (Note that in CRC (1985), I misquoted HHB and said 500 to 100 mg.)
Natural History (Poison Hemlock):
Larks and quail eat the fruit with impunity, but their meat becomes poisonous in the process. Thrush can eat the fruits but ducks are poisoned thereby (GMH).
