These common foods can be so dangerous, they can kill you

Elderberries

We see elderberries growing on trees all around at the end of summer, and they are popular in wines, jams and teas. However, elderberry seeds and leaves contain fatal levels of cyanide-producing glycoside.If the fruit is unripe or not strained correctly when used to make jam or wine, it could cause severe nausea, coma or even death.
