Abstract

To study the blood pressure, lipid and glycemic effects and safety of Vaccinium arctostaphylos leaf in the hypertensive hyperlipidemic type 2 diabetic patients. The patients took 350 mg standardized plant leaf hydro-alcoholic extract capsule (n=50) or placebo capsule (n=50) three times daily alongside conventional drugs for 2 months. At the baseline and endpoint, systolic and diastolic blood pressures and blood levels of fasting glucose (FG), 2-hr postprandial glucose (2hPPG), glycosylated hemoglobin (HbA1c), total cholesterol (TC), LDL-C, triglyceride, HDL-C, SGOT, SGPT and creatinine were determined in both groups. To evaluate the extract safety, serum SGOT, SGPT and creatinine levels were tested; also, the patients were requested to report any adverse effects. FG, 2hPPG, HbA1c, TC, LDL-C, triglyceride and systolic and diastolic blood pressures were decreased, whereas HDL-C was increased significantly in the extract group compared to those of the placebo group at the endpoint (for all cases, p<0.05). The extract did not significantly influence other parameters and no adverse effects were reported. V. arctostaphylos leaf hydro-alcoholic extract as an adjunct to the conventional drugs has additional antihypertensive as well as ...Continue Reading
