The Effect of Curcumin on Blood Glucose Patients with Type 2 Diabetes Mellitus: A Systematic Review

Type 2 Diabetes Mellitus (DM) is characterized by elevated blood glucose. Curcumin has glucose-lowering properties. This review intended to determine if Curcumin can lower blood glucose levels in type 2 diabetic patients. This review intended to determine if Curcumin can decrease blood glucose in type 2 DM patients. Curcumin has a mechanism of stimulating incretin and inhibiting digestive enzymes from reducing blood glucose levels in type 2 DM patients. We systematically searched PubMed for peer-reviewed studies examining the mechanism of Curcumin in decreasing blood glucose in type 2 DM patients. The journal criteria included in this review were a study from 2000 to 2022, randomized control trial using intervention Curcumin, an outcome variable using blood glucose, the full text of the article can be obtained, and the DM patient's age is over 18 years. Two independent reviewers retrieved data o clinical outcomes, studies, and patient characteristics using the Cochrane Risk of Bias Assessment Instrument. Quality is evaluated using the Grading of Recommendations Assessment, Development, and Evaluation system. There are 19 studies included in this research, and Three journals meet the requirements. The conclusion is that curcumin can decrease blood glucose in Type 2 DM patients.
