Gan Mai Da Zao Tang (甘麦大枣汤): The Three-Ingredient Formula That Calms the Heart and Stops Tears
Discover Gan Mai Da Zao Tang, the simplest classic TCM formula with only three ingredients — Licorice, Wheat, and Jujube Dates. Learn how it calms the spirit, treats anxiety, emotional instability, and the ancient 'Zang Zao' organ-restlessness syndrome.
What Is Gan Mai Da Zao Tang?
Gan Mai Da Zao Tang (甘麦大枣汤) is one of the simplest yet most profound formulas in TCM. Containing only three ingredients — Licorice, Wheat, and Jujube Dates — it is also one of the oldest recorded formulas, dating back to Zhang Zhongjing’s Jin Gui Yao Lue (c. 200 CE).
The name translates directly: Gan (甘, sweet/licorice) + Mai (麦, wheat) + Da Zao (大枣, jujube dates). Every ingredient is a common food, and the formula tastes sweet and pleasant — making it one of the most accessible and patient-friendly formulas in the entire TCM repertoire.
Zang Zao: The Condition It Treats
”Organ Restlessness” Syndrome (脏躁)
Gan Mai Da Zao Tang was originally designed for a condition called Zang Zao (脏躁), literally “organ restlessness” or “organ agitation.” The Jin Gui Yao Lue describes it:
“Women with Zang Zao disease experience sadness and a tendency to cry, as if they were possessed by spirits. They yawn and stretch frequently. Gan Mai Da Zao Tang is the master formula.”
In modern clinical terms, Zang Zao corresponds to:
- Emotional instability — rapid mood swings
- Frequent crying spells — often without a clear reason
- Anxiety and restlessness — inner agitation that can’t be settled
- Insomnia — difficulty falling or staying asleep
- Yawning and stretching — the body’s attempt to regulate Qi
- Panic-like episodes — feeling “beside oneself”
This pattern is caused by Heart Yin and Blood deficiency — the Heart lacks the nourishment it needs to “house” the spirit (Shen), and the spirit becomes restless and ungrounded.
The Three Ingredients
1. Gan Cao (甘草 — Licorice Root)
- Role: Chief herb
- TCM action: Tonifies Spleen Qi, nourishes the Heart, harmonizes
- In this formula: Directly tonifies the Qi that supports Heart function
2. Fu Xiao Mai (浮小麦 — Light Wheat)
- Role: Deputy herb
- TCM action: Nourishes Heart Yin, calms the spirit, stops sweating
- In this formula: The grain’s sweet, cooling nature nourishes Heart Yin and provides a gentle calming effect. “Light” wheat refers to wheat grains that float in water — these are specifically selected for their heart-calming properties
3. Da Zao (大枣 — Jujube Dates)
- Role: Assistant herb
- TCM action: Tonifies Spleen, nourishes Blood, calms the spirit, harmonizes
- In this formula: Nourishes Blood to support the Heart, while its sweet nature complements the other two herbs
Why Only Three Herbs Works
The genius of this formula lies in its simplicity. Each ingredient targets a specific aspect of the pattern:
- Gan Cao = Tonifies the Qi that supports the Heart
- Fu Xiao Mai = Nourishes the Yin that moistens the Heart
- Da Zao = Nourishes the Blood that grounds the spirit
Together, Qi + Yin + Blood = a fully nourished Heart with a settled spirit. No ingredient is wasted, and none could be removed without weakening the formula.
Clinical Applications
1. Menopausal Mood Disorders
Gan Mai Da Zao Tang is one of the most commonly prescribed formulas for menopause in TCM:
- Mood swings and emotional volatility
- Unexplained crying
- Hot flashes with anxiety
- Insomnia and restlessness
- The pattern matches perfectly: declining Kidney Yin fails to support Heart Yin
2. Postpartum Emotional Instability
- Baby blues and postpartum mood changes
- Crying spells after childbirth
- Anxiety and restlessness
- The massive Blood loss of childbirth creates Heart Blood deficiency
3. Anxiety Disorders
- Generalized anxiety with emotional lability
- Panic-like episodes
- Inner agitation and restlessness
- Difficulty calming down
4. Insomnia with Emotional Disturbance
- Difficulty falling asleep due to racing thoughts
- Waking with anxiety
- Restless, unrefreshing sleep
5. Hysteria and Conversion Disorders
Historically, this formula treated what was called “hysteria” — intense emotional episodes with crying, laughing, and agitation. In modern terms, it applies to:
- Stress-related emotional breakdowns
- Emotional episodes triggered by grief or trauma
- Somatization of emotional distress
6. Children’s Night Crying and Fussiness
- The gentle, food-based ingredients make it safe for children
- Night terrors and crying in children
- Separation anxiety

Can I make Gan Mai Da Zao Tang at home?
Yes — it is one of the easiest TCM formulas to prepare at home. The basic recipe: 9g Gan Cao (Licorice root), 30g Fu Xiao Mai (light wheat grains, available at Chinese herb shops or online), and 10 Da Zao (jujube dates, available at Asian markets).
