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

Rosary Pea

Another plant with various names, this is thought to be 100 times stronger than ricin! The name of the toxic substance is abrin and there is no doubt that this is one very potent substance you don’t want to fall foul of!

Popular through the Tropics, it has also spread to Florida although many there consider it a pest. Although poisonous if ingested, the black and red beans have a variety of uses from making rosary beads to filling maracas. Surprisingly enough for a plant so toxic the number of recorded deaths from it are relatively low. This is due to the poison inside the bean being protected by its hard exterior and the abrin absorbing into the body slowly if swallowed.
