Harmonizes Stomach comes from the classic “Treatise on Febrile Diseases”. Many medical practitioners call Ban Xia Xie Xin Tang the first formulation for gastrointestinal conditioning. The formulation uses “pungent-open, bitter-descend and sweet-tonic” as the idea of forming the formula. The pungent-open means using herbs in pungent flavour to restore digestion function of the Spleen. Bitter flavour herbs are restoring the descending function of the Stomach and sweet-tonic means it is using sweet flavours to tonic Spleen and Stomach. It is a classic formula for regulating Spleen and Stomach function. In ancient times, this formula was used to treat Spleen and Stomach’s “Pi syndrome”, and “Pi” means “sluggish“. The Pi Syndrome is characterized by those who are suffering from indigestion with symptoms of the fullness of stomach, upset, vomiting, bowel sounds, stomach acid reflux, bitter mouth, yellow and greasy tongue coating. It is currently used for gastroesophageal reflux disease, chronic gastritis, gastric ulcer, duodenal ulcer, functional dyspepsia, chronic colitis, support treatment of AIDS/HIV etc., which are dysfunction of ascending of the Spleen and descending of the Stomach, disorder of Cold and Warm of the Stomach.

Modern research shows that the formulation has the functions of anti-inflammatory, bacteriostatic and bidirectional regulation of gastrointestinal motility, and can promote the local growth and expression of the gastrointestinal tract, promote the secretion of related hormones and proteins, and improve the body’s immunity.
