Almost all plants contain calcium oxalate. Oxalic acid is a common component in plants, especially herbs, and mostly exists in the form of potassium salt or calcium salt.

Oxalic acid is not easy to be oxidized and decomposed in human body, and the products formed after metabolism are acidic substances. Eating too much will lead to imbalance of pH and poisoning in human body.

Moreover, if oxalic acid meets calcium and zinc in the human body, it will generate calcium oxalate and zinc oxalate, which are not easily absorbed and excreted.

Children need a lot of calcium and zinc for their growth and development. If the body lacks calcium and zinc, it will not only lead to bone and tooth dysplasia, but also affect intellectual development.

Excessive intake of oxalic acid can also cause stones.
