Summary
Ziziphus spinosa (Semen Ziziphi Spinosae or Suan-Zao-Ren) is a traditional Chinese medicinal seed primarily used for its sedative and hypnotic effects [PMID:36720435, PMID:32695210].
Background
Ziziphus spinosa (Bunge) Hu ex H.F. Chow is a woody plant species of the Rhamnaceae family distributed in China, Laos, Myanmar, and Iran [PMID:36720435, PMID:35222979]. The seeds, known as Suan-Zao-Ren, are widely utilized in traditional Chinese medicine and are among the most commonly prescribed phytomedicines for insomnia in Taiwan [PMID:28084039, PMID:32695210].
Traditional uses
It is traditionally used as a sedative and sleep aid [PMID:36720435]. Other ethnopharmacological uses of the Ziziphus jujuba species include treating digestive disorders, gastric ulcers, and acting as an antitussive, laxative, and hypotensive drug [PMID:28084039].
Active compounds
Over 150 compounds have been identified, including terpenoids, alkaloids, flavonoids, fatty acids, volatile oils, and polysaccharides [PMID:32695210]. Specific active components include spinosin, mangiferin, neomangiferin, ferulic acid, liquiritin, isoliquiritin, liquiritin apioside, jujuboside A and B, and swertisin [PMID:28345817, PMID:41261403, PMID:36198041].
Mechanism of action
Secondary metabolites modulate GABAergic activity and the serotonergic system [PMID:28899507]. It may ameliorate synaptic plasticity by inhibiting Aβ deposition and the JAK2/STAT3 signaling pathway [PMID:33478552]. Jujuboside B may improve neuronal apoptosis via the Bax/Bcl-2/caspase-3 signaling pathway and restore mitochondrial function [PMID:38098161]. Metabolomic analysis suggests effects on phenylalanine and tryptophan metabolism [PMID:32072764].
Clinical evidence
Evidence BInsomnia (Methadone Maintenance)
Suan Zao Ren Tang significantly improved mean total PSQI scores and average sleep efficiency compared to placebo [PMID:26346534]
Evidence BInsomnia with Anxiety
Combination of Suan Zao Ren Tang and Zhi Zi Chi Tang significantly reduced ISI, PSQI, and wake after sleep onset (WASO) scores compared to lorazepam [PMID:25793006]
Evidence BInsomnia (Chronic Hepatitis B)
Modified Suan Zao Ren Decoction improved main symptoms of insomnia and increased stage II, IV and REM sleep [PMID:18323223]
Evidence DMenopausal Sleep Difficulty
Suan Zao Ren Tang reduced mean PSQI total scores from 13.0 to 9.0 and provided superior benefit for daytime dysfunction in women with severe symptoms [PMID:21660310]
Evidence AGeneral Insomnia
A systematic review of RCTs found CHM (including Ziziphus species) similar to Western medication and placebo, but noted insufficient evidence due to poor methodological quality of trials [PMID:22440393]
Safety & adverse effects
Reported adverse events associated with Suan Zao Ren Tang include dizziness, headache, stomach ache, and diarrhea [PMID:24159351]. A case of anaphylaxis was reported in a patient with pollinosis, suggesting a possible pollen-food allergy syndrome [PMID:39552699].
Evidence summary
Evidence for insomnia is mixed; while individual RCTs show significant improvement in sleep quality and architecture [PMID:26346534, PMID:25793006], a systematic review suggests overall evidence is insufficient due to high risk of bias and poor methodological quality in available trials [PMID:22440393].
