Vitiligo is a skin disease which is easy to be diagnosed，but difficult to be treated in dermatology.It is characterized by multiple，localized or generalized pigment loss of skin mucosa，which affects the appearance and brings great psychological pressure to patients.The pathogenesis of this disease is unknown，and the therapeutic effect is not ideal at present.Traditional Chinese medicine treatment is a new hope.According to Professor ZHANG Fengchuan believes that abnormal emotions and liver-qi stagnation are the causative factors of the disease，strain is the basis of the disease，exogenous pathogenic factors and toxic pathogenic factors are the key factors of the disease，and collaterals stasis is the terminal point of the disease.Prof.ZHANG uses the dialectic combination of disease differentiation，governing exterior to infer interior，and inferring internal viscera qi and blood changes by skin lesions.Symptomatic treatment，flexible syndrome differentiation，accurate medication，clever external treatment，and the treatment of special parts that are difficult to recolor show ingenuity.I learn from Professor ZHANG Fengchuan and summarize his academic thoughts and clinical experience，which has certain reference significance for the treatment of vitiligo.
