7 Most Poisonous Plants on Earth

Wisteria

These are stunning looking purple blossoms that originate from Japan, some parts of USA as well as China but today found all around the world. The Wisteria is a creeping vine and the plant can be quite large with a thick trunk and vine branches that can extend as far as 60 ft. While the blossoms on it look fairly lovely, it is thought that entire plant is rather harmful; eating any part of the shrub can create the following:

• Migraine and headache
• Queasiness and nausea
• Fever and also diarrhea

The treatment to exposure however is quite simple consisting mainly of anti-nausea drugs.
