Patients with Type 2 diabetes were given 1600 mg of powdered ginger or a placebo supplement daily for 12 weeks. At the end of the trial, those taking ginger had significant reductions in C-reactive protein and PGE2 (two markers of inflammation). There were also positive changes in other markers, including fasting blood glucose, insulin, and triglycerides. The dosage used in the trial is equivalent to about 3/4 teaspoon of ground ginger.
