Outline
Psoriasis is a chronic inflammatory skin disease，and its pathogenesis is related to endocrine disorders，immune dysfunction and other factors. The patients with psoriasis during pregnancy have obvious improvement or self-healing tendency. Studies show that 55% of patients with psoriasis during pregnancy have improved，and estradiol is the most potent natural estrogen. And an increase in estrogen levels，especially relative to progesterone，is associated with the improvement of psoriasis. As an important hormone regulating substance，estrogen and progesterone have many biological activities，such as regulating endocrine secretion，inhibiting inflammatory reaction and promoting skin repair，which is consistent with the principle of balance between Yin and Yang in the theory of “Yang transforming into Qi，while Yin constituting form”. Yangqi is responsible for dispersing and transforming，while Yin fluid is responsible for nourishing and shaping. According to the theory of “Yang transforming into Qi，while Yin constituting form”，they are interdependent and mutually restrictive，jointly maintaining the life activities. Based on the theory of “Yang transforming into Qi，while Yin constituting form”，the keratinocytes of psoriasis are excessively proliferated，which belongs to the deficiency of Yang transforming，and the Yin forming is too much. Estrogen belongs to Yang，progesterone belongs to Yin，and estrogen and progesterone cooperate to adjust the balance of Yin and Yang，thus improving psoriasis.
