Although some experimental studies have reported effects of different extracts of chamomile on glycemic status and oxidative stress in diabetes, its possible effects on metabolic and antioxidant status of patients with diabetes have not been investigated. We hypothesized that chamomile tea consumption would ameliorate glycemic and antioxidant indices in subjects with T2
DM. To test these hypotheses, we initiated a study to evaluate the effects of chamomile tea on glycemic control (serum levels of glucose, glycosylated hemoglobin [HbA1 c], insulin, and homeostasis model assessmentinsulin resistance [HOMAIR]), and antioxidant status (total antioxidant capacity [TAC], activity of superoxide dismutase [SOD] and glutathione peroxidase [GSHPx], and malondialdehyde [MDA]) in patients with T2 DM.
