Gan Mai Da Zao Tang (Licorice, Wheat, and Jujube Decoction)

Actions

Indications

Western Uses:

• What conditions is Gan Mai Da Zao Tang used for in modern practice?

  Gan Mai Da Zao Tang treats "restless organ syndrome" (zang zao) — emotional lability, uncontrollable crying, agitation and disturbed sleep from Heart/Spleen depletion — so it is referenced for emotional and neuropsychiatric presentations: "hysteria" (in the historical sense), manic-type agitation, and convulsions.

  It is chosen for the zang-zao pattern, not for a diagnosis. A mental-health crisis, an acute manic state, and convulsions are medical emergencies requiring proper psychiatric or neurological care; this gentle formula is a traditional support, never a substitute. Traditional-use correlates only, not a treatment claim.

Originally Appeared In:

• Essentials from the Golden Cabinet (Jin Gui Yao Lue)

Notes:

• How does Gan Mai Da Zao Tang differ from other spirit-calming formulas?

  Gan Mai Da Zao Tang calms the spirit by gently nourishing a deficient Heart; most other spirit-calming formulas instead sedate an agitated Shen or address a more complex underlying pattern.

  • vs Suan Zao Ren Tang: built for insomnia from Liver-blood deficiency with heat, combining a stronger blood-nourishing/sedative herb (Suan Zao Ren) with heat-clearing and qi-regulating herbs — a more targeted sleep formula rather than a broad emotional-lability formula.
  • vs Bai He Di Huang Tang: treats “lily disease” (bai he bing), another Jin Gui Yao Lue disorder with vague physical and emotional complaints, but from yin deficiency with mild heat rather than the acute emotional outbursts of zang zao.
  • vs Tian Wang Bu Xin Dan: a much larger, more complex formula for chronic Heart/Kidney yin deficiency with insomnia and palpitations, built for sustained deficiency rather than the acute, episodic crying of zang zao.

  Gan Mai Da Zao Tang comes from the Jin Gui Yao Lue (“Essential Prescriptions of the Golden Cabinet”), attributed to Zhang Zhongjing (Han dynasty), in the chapter on miscellaneous disorders of women — though modern practice applies it to zang zao regardless of sex. It is frequently combined with Suan Zao Ren Tang, or modified with added Fu Ling and Bai He, when insomnia or lingering yin-deficiency symptoms accompany the emotional lability.

Clinical Studies & Research:

• Is there modern research on Gan Mai Da Zao Tang?

  Yes — clinical and animal research has explored the formula for depression and anxiety, broadly supporting its traditional use for mood disturbance, though clinical evidence quality is mixed.

  • Depression (systematic review and meta-analysis of RCTs): a review of 13 randomized controlled trials found the formula performed better than antidepressants specifically for post-stroke depression, but did not show superiority over antidepressants for major depression, post-surgical depression, or depression in the elderly; the authors noted the supporting evidence was low quality due to a high risk of bias in the underlying trials (PMID 25262476, Maturitas 2014).
  • Anxiolytic mechanism (animal study): in mice, the formula reduced anxiety-like behavior at higher doses without impairing motor coordination, and blocking GABA-A or 5-HT1A receptors eliminated the effect — suggesting it works through the same GABA and serotonin pathways targeted by conventional anti-anxiety medication (PMID 30723393, Front Neurosci 2019).
  • Neuropsychiatric disorders (systematic review of animal models): a review of six randomized animal studies found the formula improved outcomes across models of psychological stress, post-traumatic stress, and depression, while noting more rigorous research is still needed (PMID 28392956, J Pharmacopuncture 2017).
