There are plants in the world that are not worth getting close to, even if they don’t look dangerous. These plants may have thorns, spines, or sharp leaves that can cause a painful puncture or even a nasty slash.
Some of these plants can also produce potent poisons, so it’s essential to be aware of what you’re dealing with before touching them.

Manchineel(Hippomane Mancinella) plant is commonly found in Florida and the Caribbean. It is infamously known as “Beach Apple” because of its uncanny resemblance to apples.
The entire plant is known to be toxic and dangerous to humans and animals.
Manchineel contains toxins that can kill you if you ingest its fruit. The toxin phorbol, which is found in Manchineel, has been known to cause death in animals. It also causes severe skin allergies in humans when the skin gets exposed to the milky sap of Manchineel’s leaves and barks.
The toxin can enter your bloodstream and travel to your heart and other organs if ingested. There is no antidote for manchineel poisoning, so if you are ever exposed to the plant, be sure to get medical help as soon as possible.
Poison ivy, popularly known as “leaves of three,” and its relatives poison oak and poison sumac are pretty dangerous in the eastern regions of North America.
All three contain a chemical called urushiol, which can cause a painful rash on the skin.
If you are ever in contact with poison ivy, it’s essential to wash the area immediately with soap and water.
Poison ivy oil can also cause blisters on the skin and persistent irritation even after the rash has gone away. Do not touch your eyes or nose while you have a poison ivy rash; these areas may contain oils that can irritate your eyes and nose.
Poison ivy can also persist on clothes, shoes, tools, and other objects. Be sure to clean them thoroughly if they contact poison ivy.
