Herbsmith Rx Xiang Sha Liu Jun Zi San is a classical Chinese herbal formula recommended by holistic veterinarians to support digestive health, strengthen the spleen, and harmonize the stomach in dogs, cats, and horses. Based on the traditional formula Xiang Sha Liu Jun Zi Tang (comparable to Six Gentlemen with Aucklandia and Amomum, Eight Gentlemen, Six Gentlemen Plus, and Vladimiria and Cardamom Combination), it strengthens the spleen, harmonizes the stomach, regulates the qi, and relieves digestive discomfort. This formula builds on the foundational Si Jun Zi Tang (Four Gentlemen) by adding Chen Pi, Ban Xia, ShaRen, and Mu Xiang, making it well suited for pets presenting with spleen and stomach vacuity complicated by cold-damp stagnation in the middle burner, with signs such as poor appetite, nausea, bloating, loose stools, fatigue, and digestive irregularity. Note: Inula (Tu Xiang) is substituted for Aucklandia (Mu Xiang) in this formula, as Aucklandia is on the endangered species list; the listing retains the traditional ingredient name per label convention. Available as a concentrated powder mixed into food; cats and dogs use the Canine Blend, while horses use the Equine/Horse Blend. Dosing varies by species and body weight, and your authorizing veterinarian will provide specific guidance.

Xiang Sha Liu Jun Zi San is an eight-herb formula built on the Si Jun Zi Tang (Four Gentlemen) base, expanded with four additional herbs to address the phlegm-damp, qi stagnation, and cold accumulation that complicate the underlying spleen-stomach vacuity pattern:
Xiang Sha Liu Jun Zi San contains qi-tonifying, dampness-drying, and qi-regulating herbs, including Ren Shen, Ban Xia, and Mu Xiang (Inula), which can significantly affect cardiac function, drug metabolism, and gastrointestinal motility. Ren Shen in particular warrants close veterinary monitoring in pets on cardiac medications or stimulant therapies, as it can influence heart rate, blood pressure, and the metabolism of certain drugs. Pets currently on prescription medications should use this formula under veterinary supervision, as herb-drug interaction research in dogs and cats remains limited.
Medication categories warranting extra caution include cardiac medications, anticoagulant or antiplatelet medications, immunosuppressive drugs, gastrointestinal motility medications, and pets managing multiple concurrent prescriptions. Your authorizing veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

In Traditional Chinese Veterinary Medicine, Xiang Sha Liu Jun Zi San is indicated for spleen and stomach vacuity complicated by cold-damp stagnation in the middle burner, presenting as poor appetite, nausea, vomiting, bloating, loose stools, fatigue, and digestive irregularity. It is a good alternative to Six Gentlemen with Aucklandia and Amomum, Eight Gentlemen, Six Gentlemen Plus, and Vladimiria and Cardamom Combination, and is appropriate for pets whose digestive presentations combine spleen qi vacuity with cold-damp obstruction and qi stagnation in the middle burner.
Mix the powder directly into food or grain at the dose recommended for your pet's species and body weight. Both dogs and cats use the Canine Blend; horses use the Equine/Horse Blend. Dogs and cats receive the formula twice daily; horses receive two tablespoons twice daily for the first 20 days, then once daily for maintenance. Your authorizing veterinarian will confirm the appropriate dose and schedule for your individual pet.
As a formula that addresses a combined deficiency and excess pattern in the middle burner, Xiang Sha Liu Jun Zi San works gradually to rebuild spleen qi while resolving cold-damp stagnation. Many pets show improvement in appetite, nausea, bloating, and stool consistency within 3 to 6 weeks of consistent use. Chronic or deeply established spleen vacuity patterns may require a longer course of treatment, and your veterinarian may recommend periodic reassessment to adjust the formula or dosing as your pet's digestion responds.
Combination with complementary TCVM formulas is common in holistic veterinary practice and should be guided by your authorizing veterinarian based on your pet's full pattern diagnosis. Because this formula contains Ren Shen, which can influence cardiac function and drug metabolism, and Ban Xia, which has specific preparation requirements, veterinary oversight is especially important if your pet is on cardiac medications, gastrointestinal motility drugs, or immunosuppressive therapies, to ensure the treatment plan is appropriate for your pet's overall health status.
