Objective: Echium amoenum and Hypericum perforatum dried flowers have been used for therapy of mental disorders in Iranian traditional medicine. In this study, we assessed the efficacy of the E. amoenum and H. perforatum extracts in patients with mild to moderate depression.
Materials and methods: In an 8-week double-blind, parallel-group trial, 51 patients randomly consumed 20 mg of fluoxetine or 350 mg of herbal medicine twice daily. The Hamilton Rating Scale for Depression (HAM-D) was used to assess depression severity in patients at weeks 0, 4, and 8.
Results: According to the Hamilton score, there were no significant differences between the fluoxetine- and herbal medicine-treated groups after 4 and 8 weeks (p>0.05). Dry mouth was the only reported side effect which was significantly lower in the herbal group (p<0.05) in weeks 2 and 4.
Conclusion: E. amoenum and H. perforatum have anti-depressant properties similar to fluoxetine and they can be used to treat depression as an alternative to fluoxetine.
