A new class of medications called DPP-4 inhibitors help improve A1C without causing hypoglycemia. They work by by preventing the breakdown of a naturally occurring compound in the body, GLP-1. GLP-1 reduces blood glucose levels in the body, but is broken down very quickly so it does not work well when injected as a drug itself. By interfering in the process that breaks down GLP-1, DPP-4 inhibitors allow it to remain active in the body longer, lowering blood glucose levels only when they are elevated. DPP-4 inhibitors do not tend to cause weight gain and tend to have a neutral or positive effect on cholesterol levels. Alogliptin (Nesina), linagliptin (Tradjenta), saxagliptin (Onglyza), and sitagliptin (Januvia) are the DPP-4 inhibitors currently on the market in the US.
You’re probably referring to Salacia oblonga (or S. oblonga) an herb traditionally used in Indian medicine to help control the increase in blood sugar that follows a meal. A study published in the January 2005 issue of the Journal of the American Dietetic Association found that a drink made with the herb blunts this effect and also reduces insulin levels. S. oblonga grows in India and Sri Lanka, but is not well known in the United States, and has not been widely researched.

Indian gooseberry is one of the richest sources of vitamin C. When mixed with bitter gourd juice, its efficacy manifolds, and it can prove to be a highly effective concoction against diabetes. The mixture arouses the islets of Langerhans, that is, the isolated group of cells that secrete the hormone insulin in the pancreas. Just consume one tablespoon of Indian gooseberry juice mixed with one cup of bitter gourd juice daily for 8 to 12 weeks. It is recommended to take it first thing in the morning, if possible. The mixture has also been found to trigger insulin production. All in all, a great herbal remedy for diabetes.
Although a defect in mitochondrial function is associated with extremes of insulin resistance in skeletal muscle (30), this does not appear to be relevant to the etiology of type 2 diabetes. No defect is present in early type 2 diabetes but rather is directly related to ambient plasma glucose concentration (31). Observed rates of mitochondrial ATP production can be modified by increasing or decreasing plasma fatty acid concentration (32,33). Additionally, the onset of insulin stimulation of mitochondrial ATP synthesis is slow, gradually increasing over 2 h, and quite distinct from the acute onset of insulin’s metabolic effects (34). Although it remains possible that secondary mitochondrial effects of hyperglycemia and excess fatty acids exist, there is no evidence for a primary mitochondrial defect underlying type 2 diabetes.
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.
