Zizyphus Spinosa has been widely used for the treatment of insomnia in oriental countries. A syudy found that the active constituent in Ziziphus, sanjoinine A augments pentobarbital-induced sleeping behaviours through the modification of GABA-ergic systems. (3)

A study in climacteric women with poor sleep quality concluded Zizyphus spinosa appears to be a relatively safe and effective short-term therapeutic option in improving daytime function. (4)

A randomised, double-blind, double-dummy, placebo-controlled trial looking at the efficacy and safety of suanzaoren for chronic insomnia disorder in adults concluded that the potential side effects of hypnotic medications hinder their clinical application thus, traditional Chinese medicine is considered as an alternative option for treating insomnia.
