No. 4 Pixu decoction

No. 4 Pixu decoction is an investigational Traditional Chinese Medicine (TCM) herbal formulation developed by Xiyuan Hospital of the China Academy of Chinese Medical Sciences. It is designed for the treatment of functional diarrhea, specifically targeting the Liver Depression and Spleen Deficiency (Ganyu Pixu) syndrome as identified through TCM differential diagnosis. The decoction is part of a standardized series of formulas used in clinical trials to evaluate the efficacy of syndrome-based treatment in patients meeting the Rome III criteria for functional diarrhea. Its therapeutic goal is to regulate the Liver and strengthen the Spleen, thereby addressing the underlying disharmony that leads to gastrointestinal symptoms such as abdominal pain and frequent loose stools. In clinical studies, it is typically administered as a standardized mixture of herbal granules.
