Background: In Germany herbal medicines are traditionally frequently used. They represent an important therapeutic option, especially in self-medication.
Methods: Current systematic review articles and meta-analyses were evaluated and summarized with respect to the evidence of phytotherapeutic drugs for selected psychiatric indications.
Results: Apart from the use of St. John's wort for depression, no other herb has so far shown convincing evidence.
Conclusion: Due to the promising effects and the low side effect potential within the existing studies, further randomized controlled trials (e. g. for Passiflora incarnata, Rhodiola rosea and Lavendula officinalis) are definitely indicated.
