This investigation is a randomized controlled clinical trial to determine the effect of chamomile tea consumption on depression status, glycemic control, Blood lipid profiles and oxidative stress in depressed patients with type 2 diabetes. Inclusion criteria consists of: minimum 5 and maximum 15-year history of diabetes, mild to moderate depression (Beck test score of 35-11), age between 30 and 60 years old, patients with dyslipidemia, and exclusion criteria are: major depression (Beck test score greater than 30), which requires special treatment, people that during the interview noticed Thoughts of suicide, self-injury and a history of such in them, Pregnancy and lactation, history of hospitalization for mental illness liver disease, kidney, heart disease, thyroid disease, and central nervous system as the express themselves and etc. According to Beck depression test, people who have mild to moderate scores (Beck test score of 30-11) and do not use drugs, are selected.

Serum lipids, HbA1c and Indicators of oxidative stress including total antioxidant capacity and malondialdehyde in both groups before and after the intervention will be measured.
