    Solution

    Tomato contains oxalic acid. As it ripens the amount of Vitamin C decreases and the amount of oxalic acid increases. A plant such as wood sorrel also contains oxalic acid. Oxalate content is high in its fresh leaves and roots. Once absorbed, the oxalic acid reacts with calcium in plasma and insoluble calcium oxalate that results may precipitate in the kidneys, blood vessels, heart, lungs, and liver.
