This paper summarized professor LIN Lan's experience in treating diabetic nonketotic hemichorea from the perspective of wind. It is believed that liver-kidney,yin,deficiency is the root of diabetic nonketotic hemichorea， while internal stirring of liver wind is the branch. Additionally， pathological factors including blood stasis， phlegm-damp and fire （heat） affect the condition. On the basis of boosting,qi,and nourishing,yin,， it is recommended to put focuse on tranquilizing the liver and extinguishing wind， and simultaneously， the methods of invigorating blood and unblocking collaterals， fortifying the spleen and dissolving phlegm，and clearing heat should be combined with. In syndrome differentiation and treatment， she commonly uses insect medicines with the wandering nature such as Quanxie （,Scorpio,）， Wugong （,Scolopendra,） and Chantui （,Periostracum Cicadae,） to search and eliminate wind and unblock collaterals. Simultaneously， the theory of “three pattern differentiation” about diabetes is used to actively control the blood sugar.
