7 Most Poisonous Plants In The World – Nature’s Silent Killers

Hemlock

One of the most well-known poisonous plants is this one. This is mainly due to the mention of it in various Classical books and how it was the choice of death for Socrates in 400 B.C.. Although there are a few variations on Hemlock throughout the world, all are fatal to human if eaten. The two main different varieties are Water Hemlock found in North America and Poison Hemlock in Europe.

The active ingredients in Hemlock are coniine, cicutoxin and cicunol. In the case of coniine, which is found in poison Hemlock, this kills from the outside-in. The various limbs slowly become numb as the poison spreads before the major organs such as the lungs and heart succumb.
