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.

• Balances Cold and Heat: Restores harmony in the digestive system.

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.
