The Most Dangerous Plant In Each State

26. Massachusetts – Monkshood (Aconitum napellus)

Monkshood grows in cool, shaded areas of Massachusetts and is recognized by its hood-shaped deep blue flowers. Containing aconitine, the plant is deadly if ingested or improperly handled. Symptoms include numbness, dizziness, slowed heartbeat, convulsions, and death. Its elegant flowers have long masked its danger, historically being used in poisonings and as an arrow toxin. Even touching the plant without gloves can transfer enough toxin to cause serious health problems. Monkshood’s beauty contrasts sharply with its lethal potential, making it one of the most dangerous plants in the state.
