2) Water Hemlock (Cicuta)

This bugger is even worse than those castor oil seeds. It contains citutoxin throughout the entire plant, but in highest quantities in the roots. Cicutoxin excites the central nervous system, which sounds cool at first glance but what it really means is seizures.

If you’ve just swallowed some, this is what you can expect in around 15 minutes: nausea, vomiting, abdominal pain, tremors, confusion, weakness, dizziness and drowsiness; followed by increased body temperature, decreases in the pH of the blood (metabolic acidosis), swelling in the brain, blood coagulation disorders, muscle breakdown (rhabdomyolysis), and kidney failure. If you’re unlucky you might also face hallucinations, delirium, tingling, pricking, or numbness of your skin, dilated pupils, and coma.

See, I told you not to touch anything.
