The deconstruction of the psoriasis system based on the theory of state‐target differentiation and treatment

Abstract Psoriasis is a chronic, inflammatory skin condition characterized by its recurrent nature, often accompanied by various systemic comorbidities. It may not fully satisfy the precise diagnostic and therapeutic demands for psoriasis by the theory of syndrome differentiation and treatment of traditional Chinese medicine (TCM). Guided by Academician Tong Xiaolin's “theory of state‐target differentiation and treatment,” psoriasis can be divided into “early stage, middle stage, and late stage,” and “constraint state, excess state, and deficiency state.” Defining the target prescription and targeted Chinese materia medcia of psoriasis in each stage and establishing the system of state‐target differentiation and treatment of psoriasis could provide a new model for clinical diagnosis and treatment.
