Growing rhubarb in the garden? These pretty pink stalks are stellar in strawberry jam and berry pies, but stay away from the leafy greens. Unlike most garden goodies that offer extra value with many edible parts, the leaves of the rhubarb plant are to be avoided.

Anthraquinone glycoside is another compound to watch out for. Unlike less harmful chemicals, those found in the rhubarb leaves can cause severe symptoms, including vomiting, diarrhea and gastric pain.
