A recent study found that an herbal formula used in TCM can reduce the risk of people with prediabetes from developing Type 2 diabetes by 32 percent. In other words, simple, inexpensive and safe herbs are as effective in preventing Type 2 diabetes as the prescription drugs acarbose and metformin.
If you are concerned about your risk of diabetes, my suggestion is to start with the safe and proven methods that have been in use for centuries.
