From the past to the present, saffron and its main derivatives, as well as organoleptic properties, are commonly used in traditional medicine due to their numerous therapeutic properties such as anti-anxiety, anti-depressant, and anti-seizure effects [In the present study, saffron herbal tea was used for postmenopausal women. The results of the study showed that saffron herbal tea significantly increased the mean score of happiness in postmenopausal women, and there was a statistically significant difference between the intervention and control groups. In other words, the results showed that saffron herbal tea could have a positive effect on the participants' happiness, which was similar to the results of previous studies.The findings of Shahmansouri et al.’s [A study on the comparison of the effects of saffron and Imipramine in the treatment of mild to moderate depression showed that a 10 mg dose of saffron capsule had the same effect in the treatment of mild to moderate depression as imipramine.
