Controlling blood sugar levels is very important in preventing or reversing diabetic complications. Our clinic has been extremely successful in treating diabetes, even to the point where most of our diabetic patients can control their blood sugar levels without any medications. Part of this strategy is using acupuncture and herbs, but diet is indispensable.
   
This study found that taking 1 gram per day of a mixture of certain herbs/spices (bittergourd, jamun seeds, and fenugreek seeds) resulted in a significant reduction in blood glucose levels, both fasting and postprandial. The powder was taken for 1.5 months and then the dose was doubled for another 1.5 months (i.e., 2 grams per day).
