Gastrointestinal disorders are associated with different Chinese veterinary medicine patterns. A correct Bian Zheng or pattern differentiation is essential to determine the appropriate Chinese herbal medicine to prescribe. Si Jun Zi Tang, Shen Ling Bai Zhu San, Bu Zhong Yi Qi Tang and Xiang Sha Liu Jun Zi Tang are 4 common formulas used to tonify Qi when Spleen or Stomach Qi is Deficient. Shen Ling Bai Zhu San also dispels Dampness due to Qi Deficiency of the Spleen and Stomach. Bu Zhong Yi Qi Tang also raises Spleen Yang to treat prolapsed organs. Xiang Sha Liu Jun Zi Tang tonifies the Spleen and Stomach Qi associated with Damp-Cold Stagnation in the Zhong Jiao (Middle Burner). If Dampness Stagnates in the Spleen, Ping Wei San will eliminate Spleen Dampness and promote the flow of Qi. Da Cheng Qi Tang is used to dispel Excess-Heat Patterns of Yang Ming Fu organs (Large Intestine and Stomach). Coagulated Cold results in Qi Stagnation, leading to nausea, vomiting and pain and Ju Pi San invigorates the Zhong Jiao (Middle Burner) Yang, direct Qi downward and relieve abdominal pain. Xiang Lian Wan dries Dampness and promotes Qi circulation to regulate the Spleen and Stomach. Research from China of the clinical use, pharmacological basis and mechanisms of actions of these 8 Chinese herbal medicines will be reviewed.
