All of the participants received usual treatment. The intervention group also took 500 milligrams of curcumin after each meal (1,500 milligrams per day).

There was a decrease (improvement) in systolic blood pressure, diastolic blood pressure, LDL-C, and TNF-alpha and an increase in HDL-C in the curcumin group compared to the control group. The reductions in blood pressure and LDL-C were potentially clinically significant.

There were no differences between the groups in weight, HbA1c, fasting glucose, triglycerides, or malondialdehyde.
