Plant and Tree Leaves – Friend or Foe?

Plants and trees play a vital role in our ecosystem. They provide food, shelter, and oxygen for various species. However, it is a known fact that plants and trees can be harmful as well. Many of them produce toxic substances in their leaves to defend themselves from being eaten and to protect their species. According to research, it is estimated that around 10-25 percent of plant and tree leaves are toxic to certain animals and humans.

The level of toxicity of plant and tree leaves varies depending on the species. Some leaves are mildly toxic and can cause irritation and mild symptoms such as vomiting, diarrhea, and skin rashes. On the other hand, some leaves are highly toxic and can be fatal. For example, the leaves of the Oleander plant contain a toxic substance called oleandrin, which can cause heart failure and even death if ingested.
