To evaluate the effect of Artemisia dracunculus on glycemic control, insulin sensitivity, and insulin secretion in patients with impaired glucose tolerance (IGT). A randomized, double blind, placebo-controlled clinical trial was performed in 24 patients with diagnosis of IGT. Before and after the intervention, glucose and insulin levels were measured every 30?min for 2?h after a 75-g dextrose load, along with glycated hemoglobin A1c (A1C) and lipid profile. Twelve patients received A. dracunculus (1000?mg) before breakfast and dinner for 90 days; the remaining 12 patients received placebo. Area under the curve (AUC) of glucose and insulin, total insulin secretion, first phase of insulin secretion, and insulin sensitivity were calculated. Wilcoxon signed-rank, Mann?Whitney U, and chi-square tests were used for statistical analyses. The institutional ethics committee approved the protocol. After A. dracunculus administration, there were significant decreases in systolic blood pressure (SBP; 120.0?¡¾?11.3 vs. 113.0?¡¾?11.2?mmHg, P?.05), A1C (5.8?¡¾?0.3 vs. 5.6%?¡¾?0.4%, P?.05), AUC of insulin (56,136.0?¡¾?27,426.0 vs. 44,472.0?¡¾?23,370.0 pmol/L, P?.05), and total insulin secretion (0.45?¡¾?0.23 vs. 0.35?¡¾?0.18, P?.05), with a significant increase in high-density lipoprotein cholesterol (HDL-C) (1.3?¡¾?0.3 vs. 1.4?¡¾?0.3 mmol/L, P?.05). There were no significant differences after placebo administration. A. dracunculus administration for 90 days in patients with IGT significantly decreased SBP, A1C, AUC of insulin, and total insulin secretion with a significant increase in HDL-C levels.
