The most marked symptoms of cicuta poisoning are the violent convulsions, which remind one of the effect of strychnin.
"Special Report on Diseases of Cattle"
U.S. Department of Agriculture J.R. Mohler
By the foregoing Accounts we may observe, that Mankind, Quadrupedes and Plants seem to be infected in the same manner, by unwholesome Insects; only allowing this Difference, that the same Insect which is poisonous to Man, is not so to other Animals or Plants, and so on the contrary; we observe likewise, that Pepper which is of Use to Mankind, is poisonous to other Creatures, and tho' a Man cannot eat of the cicuta, or Hemlock, without prejudice, yet a Cow and some other Animals will eat it to their Advantage; and the Manchanese Apple, which is deadly Poison to almost every Creature, is eaten greedily by Goats, and which is strange, the Milk of those Goats is wholesome to Mankind.
"The Plague at Marseilles Consider'd"

The rose and nightshade, the hawthorn and cicuta fill the air around them with odors which our bodily senses instantly perceive.
