Depression is a common mental disorder.Due to the different discriminate thinking of traditional Chinese medicine,various ways of treatment have been formed,which can be roughly divided into 5 kinds:adjusting spirit:it is based on the treatment of adjusting spirit,the reconciliation of the viscera,the adjustment of the meridians,the differentiation of symptoms and signs from the six meridians,and the management of nutrient qi and defensive qi.Although these 5 kinds of thinking are different,they are inseparable from the viscera,meridians,and nutrient qi and defensive qi.Only when the functions of the viscera and meridians are normal and nutrient qi and defensive qi are harmonized,can the goal of relative equilibrium of yin-yang be achieved in the end,and the spirit can be cured.
