The Comparison of Anxiolytic Effects of Black Tea (Camellia sinensis) VS. Valeriana sisymbriifolium Herbal Tea on the Female Rats

Anxiety is a common disorder that many people in the society suffer from and is associated with physiological symptoms such as tachycardia, sweating, breathing disorder, feeling numb and sometimes paralysis of limbs, etc. In this study, the anti-anxiety effects of black tea (Camellia sinensis) were evaluated compared to Valerian sisymbriifolium herbal tea in female rats. For this work, 21 female rats weighing 150-200 grams were used. The animals were divided into 3 groups of seven including control, hyacinth recipient and black tea recipient. During the 24 hours before the anxiety test, the experimental groups received valerian tea and black tea with a dose of 0.3%, respectively, and the control group received drinking water instead of herbal tea. Then, the behavior of the mice was evaluated in order to investigate anxiety, motor activity for 5 minutes in an elevated plus-shaped maze. The obtained results were compared using the one-way analysis of variance test. Based on the findings of this study, no significant difference was observed between the anxiety-like behaviors of the black tea group compared to the valerian group. It seems that valerian tea in female rats not only does not have anti-anxiety effects, but also has no superiority over black tea.
