Antidolary active and anti-sugar mechanisms of the ova family (石斛; Dendrobii herba) ethanol extract (EED) were investigated. The EED was administered orally four times a day in a diabetic mouse induced by strepto Joe Toshin to reveal and reveal its pharmacological miracle through experimental studies that reduce the liver function of empty blood sugar, glythamic oxal acetate levels, insulin levels and glutamic acid trans aminaase and glutamic acid pyruvic acid trans amine. EED increased insulin secretion by glucose in RINm5F beta cells as well as intraperitoneal glucose intakes in L6 muscle cells. Thus, EED has shown great promise in displaying anti-diabetes activity not only by increasing insulin secretion but also by increasing intakes per cell, and hopes that future research on pharmacological mechanisms for quartz (Dendrobii herba) ethanol extract will be more active and contribute greatly to the treatment of diabetes.
