1. Pathogenesis of chloasma.
In traditional Chinese medicine, chloasma is associated with Yin-Yang imbalance, qi-blood imbalance, visceral depression and meridian imbalance.
1).Disorder of Yin and Yang: Under physiological conditions, the body's Yin and Yang are in a dynamic balance state, that is, "Yin Ping Yang secretion, spirit is the treatment", at this time there will be no disease. In pathological conditions, it is when the balance is destroyed, such as Yin deficiency, lack of body fluid, blood viscosity increased, flow is not smooth, stasis sedan in the meridians and collaterals, thus causing chloasma. For example, Yang deficiency, the human body lost in warmth, so that the blood in the vascular speed slowed down, slow blood flow can also produce melasma.
2). Qi-blood disorder: in physiological conditions, Qi is the handsome of blood, blood is the mother of Qi, Qi can carry blood, Qi can carry blood. Under pathological conditions, whether it is Qi disease and blood, or blood disease and qi, can be taken to eventually produce Qi stagnation and blood stasis, blood stasis stagnated in the meridians and chloasma.
3). Zang-fu disorder: under physiological conditions, the five viscera are interdependent, mutually used, and maintain the relationship between Sheng and Ke. Any one of the five viscera, whether excessive or inadequate, can destroy the balance of the relationship between Sheng and Ke, forming chloasma. Clinically, liver, spleen and kidney dysfunction are common, such as liver depression and Qi return, spleen deficiency and phlegm-dampness agglomeration, kidney deficiency and sperm-blood deficiency can produce chloasma.
4). Meridians and collaterals imbalance: Chinese medicine believes that the meridians can communicate viscera and body surface, the meridians of Qi stagnation, along the meridians and collaterals along the location of disease, occurring in the face can lead to chloasma.
