This systematic review provides up-to-date and comprehensive evidence of the efficacy and safety of Chinese herbal medicine for insomnia.
Findings from this review reveal that Chinese herbal medicine improves subjective sleep quality and quantity in people with insomnia.
Findings also show that there is no significant difference between Chinese herbal medicine and placebo with respect to the frequency and severity of adverse events.
Conclusions cannot be drawn on the comparative effectiveness between Chinese herbal medicine and benzodiazepine drugs or psychotherapy due to heterogeneity.
