Curcumin. The compound curcumin, which is found in the spice tumeric, has been shown to both boost blood sugar control and help prevent the disease. In a nine-month study of 240 adults with pre-diabetes, those who took curcumin capsules (which are available over-the-counter) completely avoided developing diabetes while a sixth of patients in the placebo group did.

Despite these encouraging results, Vulksan cautions that it's too early for diabetic patients to rely on ginseng. Herbs sold in this country are not standardized, he says, so it's difficult to know for certain what you're buying and impossible to ensure consistent dosages. Besides, his study looked only at American ginseng, and he's not certain the results would hold true for the seven other varieties. What's more, researchers haven't conclusively identified ginseng's active ingredients.
If you google “diabetes cure” you are directed to websites like WebMD and the Mayo Clinic where you find information on diet, exercise, medication, and insulin therapy, but nothing about the cure. This lack of information may have to do with the fact that Americans spend $322 billion a year to treat diabetes, $60 billion a year on weight-loss programs, and $124 billion a year on snack foods. This is about 3% of the US economy! Because so many peoples’ livelihoods are supported by diabetes and its main cause, obesity, the viral effect of people getting cured and telling others is greatly diminished.
