The aim of this study is to determine the effects of Mulbery alba leave extract on the metabolic profile, inflammatory factors, and biomarkers of oxidative stress and ALT and AST enzymes on patients with TDM2.
-
Design
-
A randomized, double-blind, controlled clinical trial on 60 patients. Computer-generated random numbers were utilized for random assignment.
-
Settings and conduct
-
60 eligible patients with type 2 diabetes and referred to outpatient Naghavi Clinic affiliated to Kashan University of Medical Sciences, Kashan, Iran will be selected in the study.
