A Comparison of the Effect of Chamomile Tea and Black Tea Consumption on Depression and Oxidative Stress Markers in Depressed Patients with Type II Diabetes: a Randomized Clinical Trial

Abstract

Introduction: According to the Public Beliefs and Chamomile combinations based on its relief effect, this trial is done to compare the effects of chamomile tea and black tea on depression and oxidative stress in depressed patients with diabetes.

Methods: This is a randomized clinical trial that was done with participation of 74 depressed patients with diabetes. Participants were randomly divided to two groups of chamomile tea (CG) and black tea (BG) (n=37), that received 3 daily cups of chamomile tea and black tea bags respectively, at least half an hour after meals. Beck Depression Inventory was completed to assess depression at baseline, after 6 and 12 weeks. TAC and MDA tests were done at the beginning and end of the study.

Results: At the end of study, 64 patients completed the study. After the study, mean scores of beck decreased significantly between the two groups. Beck scores showed significant differences in both CG (P < 0.001) and BG (P = 0.04) after the intervention, but the mean changes in scores were Obtained significantly in CG more than BG. Mean TAC was significantly decreased in both CG and BG, the mean changes showed no significant differences between the two groups.

Conclusion: This study showed that consumption of chamomile tea compared with black tea relatively decreased depression, but had no significant effects on oxidative stress.
