Drymaria cordata (Caryophyllaceae), commonly known as Abhijalo in Sikkimese-Tibetan, is a creeping herb grown in tropical and subtropical regions of the world. It is used by ethnic groups of Sikkim, North-East India, for the treatment of various diseases including diabetes. This study aimed to investigate the antidiabetic effect of methanol extract from D. cordata leaf (DCME) in streptozotocin (STZ) and nicotinamide (NA)-induced type 2 diabetes in rats. Diabetic Wistar albino rats were treated with DCME at 200 mg/kg and 400 mg/kg orally for 28 days. Metformin (150 mg/kg b.w.) was used as a reference drug. Fasting blood glucose (FBG) level; serum biochemical parameters; and liver, kidney, and antioxidant parameters were estimated, and pancreatic histopathology was performed after 28 days of treatment. Administration of DCME to STZ-NA-induced diabetic rats at 200 mg/kg and 400 mg/kg orally for 28 days exhibited statistically significant (P < 0.05) and dose-dependent reduction of FBG, glycosylated hemoglobin, serum lipid, and hepatorenal antioxidative parameters in DCME-treated groups when compared to those of diabetic controls. Histopathological studies of pancreas in DCME-treated rats showed improvement in β-cell density compared to diabetic group. The results demonstrate the significant antidiabetic potential of D. cordata leaf in albino rats plausibly by reducing oxidative stress and serum lipids levels, justifying the folkloric use of this plant in the treatment of diabetes.
