Aims: This study aimed at assessing the effects of chamomile tea consumption on glycemic control and serum lipid profile in patients with type 2 diabetes mellitus (T2DM).

Methods: This single-blind randomized controlled clinical trial was conducted on 64 individuals with T2DM (males and females) aged between 30 and 60 years. The intervention group (n = 32) consumed chamomile tea (3 g/150 mL hot water) three times per day immediately after meals for 8 weeks. The control group (n = 32) followed a water regimen for the same intervention period. Fasting blood samples, anthropometric measurements, and 3-day, 24-h dietary recalls were collected at the baseline and at the end of the trial. Data were analyzed by independent t test, paired t test, Pearson correlation test, and analysis of covariance.

Results: Chamomile tea significantly decreased concentration of HbA1C (p = 0.03), serum insulin levels (p < 0.001), homeostatic model assessment for insulin resistance (p < 0.001), total cholesterol (p = 0.001), triglyceride (p < 0.001), and low-density lipoprotein cholesterol (p = 0.05) compared with control group. No significant changes were shown in serum high-density lipoprotein cholesterol levels in both groups.

Conclusion: Chamomile tea has some beneficial effects on glycemic control and serum lipid profile in T2DM patients.
