INS and Insulin resistance: A number of clinical studies of herbal interventions (i.e., cinnamon, fenugreek, banaba, curcumin, and others) conducted among adult populations with prediabetes have demonstrated improved glycemic control, particularly with regard to reducing fasting blood glucose [18–25] and postprandial glucose [18, 22, 26–29], HbA1c [25, 30, 31], fasting insulin levels [9, 26, 28–31], homeostatic model of Insulin Resistance (HOMA-IR) [20, 28, 30, 32, 33], and increasing homeostatic model of β-cell function (HOMA-β) [27, 32].
