Remember that horrid thick medicine you were spoon-fed as a child to keep you healthy? Read on to find out just how poisonous the castor oil plant is and you will be shocked! There is an ingredient in the castor bean, which just so happens to be the deadliest plant poison on earth!

From the bean behind castor oil to the world's deadliest decorative shrub, you may be surprised to find out the incredibly lethal plants often hanging around the neighbourhood parks - or gracing your tabletop in the form of a centerpiece.
