BAN XIA XIE XIN TANG

Traditional Actions

• 
  Harmonizes the Stomach and middle burner
  
• 
  Directs rebellious qi downward
  
• 
  Disperses clumping of fluids and heat
  
• 
  Eliminates focal distention in the epigastrium
  
• 
  Stops nausea and vomiting
  
• 
  Restores proper digestive function
  

Traditional Indications

Used for complex digestive patterns involving both excess and deficiency:

• 
  Epigastric focal distention, fullness, and tightness
  
• 
  Slight or no pain in the epigastrium
  
• 
  Dry heaves or vomiting
  
• 
  Borborygmus with diarrhea
  
• 
  Reduced appetite
  
• 
  Thin, yellow, greasy tongue coating (red at tip)
  
• 
  Wiry, rapid pulse
  

This pattern is often caused by clumping of cold and heat in the epigastrium, typically following improper purging, dampness accumulation, or phlegm obstruction in a weakened middle burner.

Traditional Understanding

Ban Xia Xie Xin Tang is a harmonizing formula that addresses both root and branch:

• 
  The root: deficiency of middle burner qi
  
• 
  The branch: focal clumping from constrained fluids and heat
  

By combining downward-directing, warming, and qi-tonifying herbs, it restores normal Stomach and Spleen function, alleviates distention, and stops vomiting without aggravating obstruction.

Cautions & Contraindications

• 
  Not effective for distention caused by simple qi stagnation or retained food
  
• 
  Should be used under guidance if Spleen or Stomach is severely weak
  

Not recommended for cases with pure excess heat without clumping
