This paper summarized PANG Guoming’s clinical experience in treating type 2 diabetes from phlegm.He put forward the theory of "phlegm-induced diabetes"

and believed that "greasy obstruction"was the germination soil of type 2 diabetes. The process of phlegm turbidity and phlegm heat accumulation is the initial factor in the course of type 2 diabetes. Phlegm restraining the soil

soil obstructing wood depression

and abnormal transportation of fluid essence

food essence stagnating blood are important links in the rise of blood sugar. Phlegm heat consuming and damaging qi and qi yin damage is the internal factor of "three more and one less"or urine with sweet flavor. The treatment should focus on harmonizing the middle and treating phlegm

or resolving phlegm and descending turbid

or resolving phlegm and clearing heat to transport earth to wood

and regulate and harmonize ascending and descending.Phlegm turbid obstructing the middle syndrome should be treated with drying dampness to resolve phlegm

elevating clear qi to lower turbid qi

and with prescription of Hezhong Jiangzhuo Tiaotang Decoction（ 和中降浊调糖饮） . Internal accumulation of phlegm heat syndrome should be treated with resolving phlegm and clearing heat

harmonizing the middle and regulating sugar

and with prescription of Qingre Huatan Tiaotang Decoction（ 清热化痰调糖饮） .
