This paper introduces LI Saimei′s experience in treating diabetes. It is believed that in addition to dryness-heat due to yin deficiency syndrome

yang deficiency and yang hyperactivity syndrome is also a common type of diabetes

especially for patients living in the south of Qinling

whose constitution is usually yin deficiency. Clinically

treatment of soothing stagnation and purging fire as well as conducting fire back to its origin is applied. And the treatment is performed according to three levels: yang hyperactivity superior to yang deficiency

yang hyperactivity equal to yang deficiency

and yang deficiency superior to yang hyperactivity. Moreover

during the course of disease

stagnation and stasis occur after long-term illness. Therefore

liver-soothing

qi-regulating

blood-activating and stasis-resolving medicines can be added into the prescriptions.
