Designed to balance cold and heat in the body, it relieves digestive issues, reduces bloating, and disperses stagnation.
This versatile remedy is widely used for conditions like stomach pain, vomiting, and indigestion caused by disharmony in the spleen and stomach. This article explores its ingredients, benefits, modern uses, dietary support, and precautions in a clear, accessible way, using common plant names.
Ingredients of Ban Xia Xie Xin Tang
Ban Xia Xie Xin Tang combines seven herbs, each contributing to its therapeutic effects:
Ban Xia (Pinellia, 12g): Dries dampness and relieves nausea.
Huang Qin (Skullcap, 9g): Clears heat and reduces inflammation.
Gan Jiang (Dried Ginger, 9g): Warms the stomach and stops vomiting.
Ren Shen (Ginseng, 9g): Boosts energy and supports digestion.
Huang Lian (Coptis, 3g): Clears heat and soothes the stomach.
Da Zao (Jujube Dates, 4 pieces): Nourishes the spleen and balances the formula.
Zhi Gan Cao (Roasted Licorice, 9g): Harmonizes the herbs and protects the stomach.
Preparation: Boil the herbs in 1.2 liters of water until reduced to 600ml, strain, and boil again to 300ml. Take 100ml warm, three times daily. Modern methods may use decoctions or pre-made pills, dosed as prescribed.

How the Herbs Work Together
The herbs in Ban Xia Xie Xin Tang follow the traditional Chinese medicine principles of monarch, minister, assistant, and envoy:
Ban Xia (Pinellia): The primary herb (monarch), it dries dampness, clears phlegm, and relieves vomiting and bloating.
Gan Jiang (Dried Ginger): A minister herb, it warms the stomach, softens Pinellia’s drying effect, and stops nausea.
Huang Lian (Coptis): Another minister, it clears heat and calms stomach fire, balancing Pinellia’s warmth.
Huang Qin (Skullcap): An assistant, it clears damp-heat and reduces vomiting and diarrhea.
Da Zao (Jujube Dates): An assistant, it nourishes the spleen and softens the formula’s intensity.
Zhi Gan Cao (Roasted Licorice): The envoy, it harmonizes the herbs and protects the stomach from irritation.
Ren Shen (Ginseng): Also an envoy, it boosts energy and prevents the formula from weakening digestion.
This balanced blend restores Ascending and descending, addressing cold-heat imbalances and restoring spleen-stomach harmony.
Effects and Indications
Main Effects:
Balances cold and heat to restore digestive harmony.
Relieves bloating, stagnation, and lumps in the stomach.
Harmonizes the spleen and stomach to improve digestion.
Indications: Ban Xia Xie Xin Tang treats “pi” syndrome, a condition where cold and heat intertwine, causing stagnation in the middle burner (spleen and stomach). Symptoms include:
Abdominal bloating or fullness (distended but painless)
Vomiting or nausea
Diarrhea
Tinnitus (ringing in the ears)
Sticky, slightly yellow tongue coating
This syndrome often results from improper use of laxatives, which weakens the middle burner’s yang qi, allowing heat to invade and disrupt the spleen’s ascending and stomach’s descending functions.

Action | Disperses pi and dissipates masses through the combination of cold and warm medicinals. |
Indication | Pi is caused by the binding of cold and heat, marked by stuffiness below the heart, fullness without pain, vomiting, borborygmus, diarrhea, and a slightly yellow, greasy coating. |
Pathogenesis | The pattern of pi treated by Ban Xia Xie Xin Tang is originally caused by inappropriate purgative treatment in a Xiao Chai Hu Tang pattern. The purge damages the yang in the middle jiao and the shaoyang pathogenic heat invades inward. The result is pi below the heart because of the binding of cold and heat. Pi describes an obstruction, which causes the interaction between the upper jiao and lower jiao to fail. Pi below the heart actually refers to pi in the stomach cavity. The spleen and stomach are located in the middle jiao, which is the hub of the ascending and descending movement of qi. Since center qi weakness leads to binding of cold and heat, pi may result. The spleen is a yin zang that governs ascent, while the stomach is a yang fu that governs descent. Damaged center qi may cause disordered ascending and descending, which may lead to vomiting, borborygmus and diarrhea. The pathogenesis of this pattern is quiet complicated because the middle jiao disharmony and the disordered ascending and descending are due to the binding of cold and heat, as well as a deficiency-excess complex. The treatment is to harmonize the cold and warm aspects, boost qi, harmonize the stomach, dissipate masses, and disperse pi. |
Clarification | About acrid medicinals that open and bitter medicinals that promote descent This is a particular type of combination that uses acrid warm medicinals in combination with bitter cold medicinals. This combined method is used to harmonize the cold and warm aspects, diffuse and unblock qi movement, direct qi downward and arrest vomiting, and disperse pi and eliminate fullness. It is applicable for binding of cold and heat or damp-heat accumulation, characterized by pi and fullness, diarrhea, and vomiting. In this formula, acrid warm (hot) ban xia and gan jiang are used together with bitter cold huang qin and huang lian in order to manifest the therapeutic effect of acrid medicinals that open and bitter medicinals that promote descent. |
