Chai Hu Shu Gan is a seven-herb formula building on the classical Si Ni San framework with added Qi-moving, Blood-invigorating, and Stomach-harmonizing herbs to create one of the most comprehensive and widely used Liver Qi stagnation formulas in the Chinese materia medica:
Chai Hu Shu Gan contains Liver Qi-soothing herbs (Chai Hu, Xiang Fu), Qi-moving herbs (Zhi Ke, Chen Pi), a Blood-invigorating herb (Chuan Xiong), a Blood-nourishing herb (Bai Shao Yao), and a harmonizing herb (Gan Cao). Chai Hu has documented interactions with certain immunosuppressive and hepatic medications. Gan Cao (Licorice root) may interact with diuretic and antihypertensive medications with long-term use. Pets on prescription medications should use this formula under veterinary supervision, as herb-drug interaction research in dogs, cats, and horses remains limited.
Medication categories warranting extra caution include immunosuppressive medications, hepatic medications, diuretic medications (with long-term Gan Cao use), and multiple concurrent prescription medications. Use for up to 6 months, or as directed by your veterinarian. Your veterinarian can determine appropriateness based on the patient's condition, medications, and laboratory results.

Chai Hu Shu Gan is used in TCVM for Liver Qi stagnation - one of the most common patterns in companion animals and horses, particularly those under physical or emotional stress. In TCVM, the Liver is responsible for ensuring smooth Qi flow throughout the body; when Liver Qi becomes stagnant, Qi flow is obstructed, leading to signs that may include irritability, tension, reluctance to move, flank sensitivity, digestive irregularity, and emotional reactivity. The formula is particularly valued for its balanced approach: it soothes Liver Qi through Chai Hu and Xiang Fu, moves Qi through Zhi Ke and Chen Pi, nourishes and protects Liver Blood through Bai Shao Yao, and harmonizes the Spleen through Gan Cao - simultaneously addressing the stagnation and protecting the Blood and Spleen from the effects of Liver over-action. The manufacturer lists no contraindications for this formula.
For horses, give 3g (2.5 large scoops) of concentrated powder twice daily, or as directed by your veterinarian. For dogs and cats using the 90g Concentrated Powder, give 0.1g to 0.25g per 10 to 20 lb body weight twice daily; the small scoop holds approximately 0.3g. For the 0.5g Concentrated Capsule format, give one capsule per 20 to 40 lb body weight twice daily; for small dogs and cats under 10 lbs, give one 0.2g concentrated capsule once daily, or as directed by your veterinarian. Teapills can be hidden in food or a soft treat. Use for up to 6 months, or as directed by your veterinarian.
Chai Hu Shu Gan Wan originates from Jing Yue Quan Shu (Collected Treatises of Zhang Jing-Yue), written by the celebrated Ming dynasty physician Zhang Jie-Bin in 1624. Zhang Jie-Bin, also known as Zhang Jingyue, was one of the most influential physicians of the Ming dynasty and a major contributor to the development of Chinese medicine theory, particularly in the areas of Yin-Yang, the Eight Principles, and the treatment of deficiency patterns. His formulation of Chai Hu Shu Gan Wan built on the earlier Si Ni San framework from the Han dynasty Shang Han Lun, adding Xiang Fu, Chen Pi, and Chuan Xiong to create a more comprehensive Liver Qi stagnation formula that addresses both the Qi stagnation and the Blood stagnation, digestive, and Blood deficiency components that accompany it. The formula has remained one of the most widely used and referenced Liver Qi stagnation formulas in both human and veterinary TCVM practice for four centuries.
Chai Hu Shu Gan is distinguished from other Liver Qi stagnation formulas by its comprehensive multi-layer approach: it simultaneously soothes Liver Qi (Chai Hu, Xiang Fu), moves and breaks Qi stagnation (Zhi Ke, Chen Pi), invigorates Blood to address the Blood stagnation that accompanies Qi stagnation (Chuan Xiong), nourishes Liver Blood to address the deficiency that can drive stagnation (Bai Shao Yao), and harmonizes the Spleen to prevent Liver over-control of the digestive system (Gan Cao). Compared to simpler Liver Qi formulas that primarily soothe or move Liver Qi, Chai Hu Shu Gan is considered a more complete formula for Liver Qi stagnation patterns with a Blood stagnation and digestive component. Your veterinarian will determine which formula best matches your pet's specific TCVM pattern through a full evaluation.
