In fact, we are still taking chances and learning about newly-discovered plant life and vegetation all over the world.

Wild and Cultivated Cherries

Cherries are delicious, but the twigs and stems contain a compound that releases cyanide. This causes death, but not before severe gasping, excitement, and prostration.

Oak Trees

Water Hemlock

These are found in swampy areas and marshes, and are fatal if any parts are consumed. Consumption will result in painful and violent seizures, followed by sudden death.
