Recommended by holistic veterinarians, Jing Tang Xiao Zhang San is a Traditional Chinese Veterinary Medicine (TCVM) herbal formula that breaks down Qi stagnation and resolves stagnation to address patterns of Qi stagnation with abdominal distension, Damp accumulation, and gastrointestinal stagnation in dogs, cats, and horses. Based on a formula from Xue (Traditional Chinese Veterinary Medicine) written by Yu Chuan in 1979, this seventeen-herb formula combines a core Qi-moving and Qi-breaking layer (Xiang Fu, Qing Pi, Chen Pi, Wu Yao, Zhi Shi, Hou Po, Chuan Mu Xiang, Da Fu Pi), a Dampness-transforming and urination-promoting layer (Huo Xiang, Hua Shi, Tong Cao), a Qi-descending and food stagnation-resolving layer (Lai Fu Zi, Qian Niu Zi), an Intestine-moistening and bowel-moving herb (Yu Li Ren), a Heat-purging and stagnation-clearing herb (Da Huang), and a Blood-nourishing and Liver-softening pair (Bai Shao Yao, Dang Gui) to comprehensively address the complex Qi stagnation, Dampness, and abdominal distension pattern. Available as a 600g powder. Do not use during pregnancy. Stop administration immediately if the patient develops diarrhea or other unusual signs. May be used as needed for up to 3 months, or as directed by your veterinarian. Dosing varies by species and body weight; your authorizing veterinarian will provide specific guidance.

Xiao Zhang San is a seventeen-herb formula from Yu Chuan's Xue (Traditional Chinese Veterinary Medicine, 1979), organized around a comprehensive Qi-moving and distension-reducing foundation (Xiang Fu, Qing Pi, Chen Pi, Wu Yao, Zhi Shi, Hou Po, Chuan Mu Xiang, Da Fu Pi), a Dampness-transforming and urination-promoting layer (Huo Xiang, Hua Shi, Tong Cao), a food stagnation-resolving and bowel-moving layer (Lai Fu Zi, Qian Niu Zi, Yu Li Ren), a stagnation-purging and Heat-clearing herb (Da Huang), and a Blood-nourishing and Liver-softening pair (Bai Shao Yao, Dang Gui):
Xiao Zhang San contains multiple Qi-moving and stagnation-breaking herbs including Xiang Fu, Qing Pi, Chen Pi, Hou Po, Zhi Shi, and Wu Yao; a purgative herb (Da Huang) and a strong water-draining herb (Qian Niu Zi) that may affect electrolyte balance; Blood-invigorating herbs including Dang Gui and Bai Shao Yao; Dampness-draining herbs (Hua Shi, Tong Cao) that promote urination; and Zhi Shi, whose synephrine constituent may interact with cardiovascular medications. Da Huang's anthraquinone constituents may affect electrolyte balance and interact with cardiac medications and diuretics; Dang Gui may interact with anticoagulant medications; Hou Po's honokiol may interact with CNS-affecting medications and sedatives; Qian Niu Zi's cathartic action may increase the rate of absorption or excretion of concurrently administered medications. Stop administration immediately if the patient develops diarrhea or other unusual signs. Do not use during pregnancy. Dogs, cats, and horses on prescription medications should use this formula under veterinary supervision, as herb-drug interaction research in these species remains limited.
Medication categories warranting extra caution include cardiovascular medications, anticoagulant or antiplatelet medications, diuretics, CNS-affecting medications and sedatives, cardiac medications, and animals managing multiple concurrent prescriptions. May be used as needed for up to 3 months, or as directed by your veterinarian. Your veterinarian can determine appropriateness based on your animal's condition, current medications, and laboratory results.

Xiao Zhang San is indicated for dogs, cats, and horses with TCVM patterns of Qi stagnation with abdominal distension, Dampness accumulation, food stagnation, and gastrointestinal stagnation, where Qi stagnation has resulted in abdominal bloating, fullness, and Dampness accumulation in the Spleen, Stomach, Liver, and lower Jiao channel system. Holistic veterinarians frequently prescribe it as a comprehensive TCVM abdominal distension and Qi stagnation-clearing formula for complex multi-channel Qi stagnation presentations. Do not use during pregnancy. Stop administration immediately if the patient develops diarrhea or other unusual signs. May be used as needed for up to 3 months, or as directed by your veterinarian. Your authorizing veterinarian will confirm the appropriate TCVM pattern diagnosis before recommending Xiao Zhang San.
Xiao Zhang San is available as a 600g powder that mixes into food. For dogs and cats, the guideline is 0.5g per 10 to 20 lbs of body weight twice daily, or as directed by your veterinarian. For horses, the guideline is 15g twice daily as a top dressing on feed, or as directed by your veterinarian. Do not use during pregnancy. Stop administration immediately if the patient develops diarrhea or other unusual signs. May be used as needed for up to 3 months, or as directed by your veterinarian.
Xiao Zhang San addresses a complex, multi-channel Qi stagnation pattern involving the Liver, Spleen, Stomach, lower Jiao, and San Jiao simultaneously, which requires Qi-moving herbs with different channel affinities and different strengths of Qi-moving action to comprehensively clear the stagnation. Xiang Fu is the primary Liver Qi-regulating herb with broad Triple Burner affinity; Qing Pi provides the most aggressive Liver Qi-breaking action; Chen Pi regulates middle Jiao Spleen and Stomach Qi with a milder, more harmonizing action; Wu Yao specifically addresses cold-type Qi constraint in the lower Jiao; Zhi Shi and Hou Po break the most established Qi accumulations and reduce abdominal distension; Chuan Mu Xiang targets gastrointestinal Qi stagnation specifically; and Da Fu Pi descends Qi and promotes urination simultaneously. No single Qi-moving herb covers all these channels and stagnation depths simultaneously - the formula's breadth of Qi-moving coverage is what makes it specifically suited to the complex, multi-channel abdominal distension pattern, or as directed by your veterinarian.
In TCVM theory, the Liver governs the smooth flow of Qi throughout the body and stores Blood. When Liver Qi is stagnant, it often co-exists with some degree of Liver Blood or Yin insufficiency - either because Blood deficiency fails to nourish and soften the Liver, allowing Qi to stagnate more easily, or because chronic Qi stagnation eventually impairs Blood production and circulation. The inclusion of Bai Shao Yao and Dang Gui in Xiao Zhang San serves two purposes: first, they nourish Blood and soften the Liver, addressing the Blood-nourishing deficiency root that contributes to Liver Qi constraint; second, they moderate and counterbalance the formula's seventeen herbs of predominantly pungent, bitter, drying, and draining nature. Without Bai Shao Yao and Dang Gui, the formula's aggressive Qi-breaking, Dampness-drying, and stagnation-purging strategy could excessively dry Yin and Blood over the treatment course. This inclusion of a small Blood-nourishing counterbalance within an otherwise aggressively moving and draining formula is a classical TCVM formulation principle - move and drain the excess, but protect and nourish the body's foundations simultaneously, or as directed by your veterinarian.
