-----Property-----
Oxalic acid is a metabolite of the organism, it is widely distributed in plants, animals and fungi in the body, and play different functions in different living body.
Since oxalic acid can reduce the bioavailability of mineral elements in the human body easy to form calcium oxalate and calcium cause kidney stones, so acid is often considered to be a mineral element absorption and utilization of the antagonist.
