The main clinical manifestations of diabetic cognitive impairment(DCI) are memory loss and attention decline.If not prevented early，it is easy to develop into dementia，which seriously affects work and life of people.DCI is characterized by yin deficiency，dryness-heat，block of sweat pore，and obstruction of phlegm，blood stasis，and toxin.Wind is the primary factor of all diseases，which promotes the progress of DCI with phlegm，blood stasis，and toxin.Wind-dispelling drugs have the functions of “ascending，dispersing，expelling，dredging，drying，moving，and opening sweat pore”，and have been widely used in clinical practice.In the treatment of DCI，the ascending and dispersing properties can promote the drugs to directly act on the affected sites，and the combination of other drugs can increase the strength of promoting blood circulation，resolving phlegm，and removing toxin.Its ability of dispelling wind and dredging collaterals can dissipate the tangible pathogens，providing ideas and methods for the clinical work of DCI.
