Abstract: Tic disorders（TD） is a common neuropsychiatric disorder occurring in childhood. The clinical manifestations are uncontrollable and irregular limb tics and/or vocal tics. The audible and visual tic symptoms can cause a variety of psychological，learning and behavioral problems in children，bringing enormous economic pressure and burden to the family and society. The main etiology of this disease is neurotransmitter dysfunction in the brain，trace element imbalance and neuroinflammation，and its occurrence，development and recurrence are closely related to exogenous factors，diet and emotion. Professor Shi Zhenggang is a famous traditional Chinese medicine doctor in Gansu Province. He has long been devoted to the prevention and treatment of children's heart and liver diseases with traditional Chinese medicine. Professor Shi Zhenggang believes that phlegm obstructing，blood stasis and predominate wind causing motion is the key to tic disorder. Also, because TD has a long course of disease and has its own pathogenic characteristics at different stages，Prof. Shi suggests that TD should be treated with liver as the center and puts forward the theory of three-stage treatment: treating from lung in the initial stage，promoting lung and clearing liver，and removing external wind to prevent tic；treating from heart in the acute period，clearing the heart and calming the liver，and calming endogenous wind to stop tic；treating from spleen in the remission period，mobilizing the spleen and soothing the liver，and eliminating phlegm and blood stasis to eliminate tic. This theory reflects the individualized characteristics of TCM treatment for this disease, and has reference and significance in guiding the treatment of TD.
