Attention! 6 Fruits And Veggies Are Threatening Your Health

4. Rhubarb Leaves

Rhubarb, the most commonly-used ingredient in America's favorite strawberry-rhubarb pie, is another plant to be wary of. Though the suspiciously pink, celery-shaped stalk is safe to use as a sweet application, its leaves are hazardous. You'll always be on your toes if you know that about 25 grams of oxalic acid, high in rhubarb leaves, is enough to cause death! Better stay away from this ruthless killer before it's too late.
