How do Chinese medicine think chloasma is caused?

Chinese medicine actually has knowledge about chloasma, so how does Chinese medicine think chloasma is caused?

Chinese medicine believes that if the zang-fu organs are dysfunctional, the meridians are blocked and the qi and blood are insufficient, it can be reflected in the face. The occurrence of chloasma is related to the imbalance of viscera, qi and blood, and it is a reflection of systemic diseases, which is most closely related to the dysfunction of liver, spleen and kidney.

According to the characteristics of different diseases, Chinese medicine divides chloasma into different types, among which there are three common types: stagnation of liver qi, deficiency of spleen and soil, and deficiency of kidney water. Therefore, patients with chloasma can choose drugs for soothing liver, clearing liver, nourishing yin and tonifying kidney and foods containing vitamins and trace elements to form medicated diet. Medicinal diet is a good method of "homology of medicine and food" based on "homology of medicine and food", which is a great pioneering work of the Chinese nation.
