These berries are extremely poisonous if you eat them, according to the Missouri Botanical Garden.
That's why many animals avoid the plant. Humans should, too.
Aristolochia clematitis, "Birthwort"
Birthwort is commonly used in traditional medicine, even though it can cause kidney failure.
The US Food and Drug Administration put out a warning encouraging consumers to stop taking "medicines" with aristolochic acid in them because of this side effect.
The plant's roots and stem are full of this acid and therefore poisonous, so it's best to avoid ingesting this altogether.
Hippomane mancinella, "Manchineel Tree," “Beach Apple”
The Manchineel Tree is found throughout Central America and the southernmost United States.
In Spanish, it's also known as the "tree of death" because you could die if you eat its fruit, which look like little apples.
Its sap can also cause painful blisters, and burning it can cause temporary blindness, according to the University of Florida.
Basically, all parts of the Manchineel can do some serious damage. Steer clear.
