Jujube
Herb ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
Jujube seed, often called suan zao ren, is used in traditional Chinese medicine formulas for insomnia, restlessness, and calming. Clinical evidence is emerging and often comes from multi-herb formulas such as Suan Zao Ren Tang or Zao Ren An Shen, so effects cannot always be attributed to jujube alone. It may cause sedation and should be used cautiously with sleep medications, alcohol, and other calming supplements.

The bottom line
Evidence rating emerging. Most-documented uses: may support sleep quality in traditional formulas, may reduce restlessness, may promote calm. 3 sources indexed (2013–2020), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Jujube seed contains jujubosides, flavonoids, alkaloids, and saponins that may influence GABAergic and serotonergic signaling, hippocampal excitability, and stress-related arousal in preclinical models. Formula-based clinical trials suggest possible sleep benefits, but study quality varies and single-herb evidence is limited. Sedation and additive CNS effects are the main practical safety issues.3
Dosing & protocol.
Often taken in the evening. Take with food if stomach upset occurs.
What it actually costs.
