  Type 2 diabetes is a metabolic disorder which is strongly associated with cardiovascular risk and requires intervention to improve glycemic control and other cardiovascular risk factors. In this study, hydro alcoholic extract of Nettle (Urtica dioica) on some cardiovascular risk factors in type 2 diabetic patients were studied. A randomized single-blind clinical trial of 50 men and women with type 2 diabetes aged 52.39±13.75 years was conducted. Patients were adjusted by age, sex and duration of diabetes, then randomly divided into an intervention and control groups, they received, 100 mg kg-1 day-1 nettle extract or placebo in 3 portions for 8 weeks. Fasting Blood Sugar (FBS), glycated Hemoglobin (HbA1C), Fasting Insulin concentration, Total Cholesterol (TC), Low Density Lipoprotein (LDL), High Density Lipoprotein (HDL), Triglycerides (TG), systolic blood pressure(SBP), Diastolic blood pressure (DBP) were measured, TC/HDL-cholesterol, LDL/ HDL cholesterol ratio , Log (TG/HDL-c) and Insulin Resistance were calculated, at the beginning and end of the study. The data were analyzed by SPSS version 18, p<0.05 was considered significant in all measurement. After 8 weeks, FBS ,HbA1C , TG , Log (TG /HDL-c) and SBP showed a significant decrease and HDL-cholesterol showed a significant increase in the intervention group compared to the control group (p<0.05). The findings of this study suggest that the hydro alcoholic extract of nettle has a beneficial effect on FBS, HbA1C, TG, HDL-c concentration, Log (TG /HDL-c) and SBP in patients with type 2 diabetes after eight weeks intervention.

  Type 2 diabetes is a metabolic disorder that is strongly associated with cardiovascular risk. Inflammation is a potential risk factor for cardiovascular disease. In this study, hydro alcoholic extract of Nettle (Urtica dioica) on insulin sensitivity and some inflammatory indicators in type 2 diabetic patients were studied. A randomized double-blind clinical trial on 50 men and women with type 2 diabetes was done for 8 weeks. Patients were adjusted by age, sex and duration of diabetes, then randomly divided into two groups, an intervention and control group. They received, 100 mg kg-1 nettle extract or placebo in three portions a day for 8 weeks. Interleukin 6 (IL-6), Tumor Necrosis Factor-alpha (TNF-α) , High Sensitive C-Reactive protein (hs-CRP) and Fasting Insulin concentration were measured. Insulin Sensitivity was calculated, at the beginning and the end of the study. The data were analyzed by SPSS version 18, p<0.05 was considered significant for all variables. After 8 weeks, IL-6 and hs-CRP showed a significant decrease in the intervention group compared to the control group (p<0.05). The findings showed that the hydro alcoholic extract of nettle has decreasing effects on IL-6 and hs-CRP in patients with type 2 diabetes after eight weeks intervention.

  Diabetes type 2 is a metabolic disorder that characterized by hyperglycemia and insulin resistance. Hyperglycemia and impairment of oxidant/antioxidant balance, can increase oxidative stress and increase risk of cardiovascular disease. In the present study, Effects of hydro alcoholic extract of Nettle on oxidative stress in type 2 diabetes were evaluated. Fifty patients (27 men, 23 women) with type 2 diabetes patients were studied. They received 100 mg kg-1 of nettle extract of body weight hydro alcoholic for 8 weeks. At the baseline and end of 8th weeks of intervention blood levels of oxidative stress markers were measured. Data was analyzed by SPSS version 18, p<0.05 was considered significant for all variables. After 8 weeks, Total Antioxidant Capacity (TAC) and Superoxidant Dismutase (SOD) showed a significant increase in the intervention group compared to the control group (p<0.05). The findings showed that the hydro alcoholic extract of nettle has increasing effects on TAC and SOD in patients with type 2 diabetes without no changes in Malondialdehyde (MDA) and Glutathione Peroxides (GPX) after eight weeks intervention.
