What It Supports

  • Spleen qi tonification and digestive strength: Tonifies the spleen qi and strengthens the spleen's transformation and transportation functions using the four classical herbs of Si Jun Zi Tang, restoring the qi needed to power the spleen's processing of food and fluids into qi and blood, addressing the reduced appetite, soft or loose stool, abdominal fullness, and digestive weakness that arise from spleen qi deficiency in dogs, cats, and horses.
  • Overall qi tonification and vitality support: Tonifies the overall qi and supports the body's fundamental vitality using Ren Shen as the principal qi tonic, addressing the fatigue, low energy, muscle weakness, and general lack of vitality that arise from insufficient qi failing to power the body's activities, organ functions, and wei qi (defensive qi) response.
  • Muscle strength and body condition support: Supports muscle mass and body condition through the spleen's qi-generating and muscle-nourishing functions, addressing the muscle weakness, atrophy, or poor body condition that arise when spleen qi deficiency fails to generate sufficient qi and blood to nourish the muscles and maintain appropriate body condition in aging, recovering, or chronically debilitated animals.
  • Defensive qi and immune support: Supports the wei qi (defensive qi) through the spleen qi-tonifying and lung qi-supporting actions of the formula, addressing the reduced resistance and susceptibility to illness that can accompany chronic spleen qi deficiency when insufficient spleen qi fails to generate the lung qi and wei qi needed to maintain the body's defensive functions at the exterior.

TCVM Principles

  • Primary action: Tonifies the yuan qi (original qi) and spleen qi using Ren Shen as the principal herb, supplemented by Bai Zhu to strengthen the spleen and dry dampness and Fu Ling to strengthen the spleen, leach out dampness, and calm the spirit, providing the substantial qi tonification needed to restore the spleen's transformation and transportation functions and the body's overall vitality from the qi deficiency root.
  • Secondary action: Harmonizes the formula, moderates the tonic properties of the other herbs, and tonifies the spleen and heart qi with Zhi Gan Cao, preventing the formula from over-consolidating by providing the harmonizing action that ensures the tonified qi is distributed appropriately throughout the middle burner and all organs, and enhancing the palatability and digestive tolerability of the formula to support sustained use over the longer treatment courses needed to adequately restore spleen qi deficiency.

Available Forms

  • Powder - Canine Blend (for dogs and cats): Available in 75 g, 150 g, 500 g, 900 g, and 1200 g sizes; mix into food at the recommended dose for your pet's weight. Cats and dogs both use this blend.
  • Powder - Equine/Horse Blend (for horses only): Available in 150 g, 500 g, 900 g, and 1200 g sizes; mix into grain at the recommended dose for your horse.

  • 30-80 lbs: 1 tsp twice daily, or as prescribed
  • 80-120 lbs: 1½ tsp twice daily, or as prescribed
  • Over 120 lbs: 2 tsp twice daily, or as prescribed

Active Ingredient TCVM Actions

Si Jun Zi Tang is the classical four-herb foundational qi tonification formula of Chinese medicine, combining a principal yuan qi and spleen qi tonic, a spleen-strengthening and dampness-drying herb, a spleen-strengthening and dampness-leaching herb, and a harmonizing and tonic moderator to tonify the qi and strengthen the spleen from four complementary angles:

  • Ren Shen (Radix Ginseng) - Ginseng Root: Principal herb; powerfully tonifies the yuan qi (original qi) and spleen and lung qi, generates fluids, and calms the spirit; the most important single qi tonic in the Chinese materia medica and the foundational herb of the formula, directly addressing the yuan qi and spleen qi deficiency root that drives all aspects of the spleen qi vacuity pattern including the fatigue, reduced appetite, muscle weakness, and digestive insufficiency, providing the deep qi tonification needed to restore the spleen's transformation and transportation functions and the body's overall vitality and wei qi response.
  • Bai Zhu (Rhizoma Atractylodis Macrocephalae) - White Atractylodes Rhizome: Strengthens the spleen and stomach, dries dampness, and stabilizes the exterior; the principal spleen-strengthening and dampness-drying herb of the formula, directly strengthening the spleen's transformation and transportation functions at the organ level, drying the dampness that accumulates when spleen qi deficiency fails to transform fluids properly, and working with Ren Shen to simultaneously tonify the spleen qi from the yuan qi level and strengthen the spleen's functional capacity at the organ level.
  • Fu Ling (Sclerotium Poriae Cocos) - Poria / Tuckahoe / China Root: Strengthens the spleen and stomach, leaches out dampness, calms the spirit, and quiets the heart; the spleen-strengthening and dampness-leaching complement to Bai Zhu's dampness-drying action, removing accumulated dampness through the urine to relieve the dampness that the deficient spleen has failed to transform and transport, calming the spirit to address any anxiety or restlessness that accompanies the qi deficiency pattern, and working with Bai Zhu to provide both dampness-drying and dampness-leaching action that comprehensively resolves the dampness accumulation aspect of spleen qi deficiency.
  • Zhi Gan Cao (Honey-fried Radix Glycyrrhizae Uralensis) - Honey-fried Licorice Root: Tonifies the spleen and stomach qi, moderates and harmonizes the actions of all herbs in the formula, and generates fluids; the harmonizing and moderating herb that makes the formula's combined qi-tonifying and dampness-resolving action both more effective and gentler for sustained use, moderating the strong tonic properties of Ren Shen to prevent over-consolidation, tonifying the spleen and heart qi alongside Ren Shen and Bai Zhu, and ensuring the formula's actions are well coordinated and tolerated over the longer treatment courses needed to adequately restore spleen qi deficiency. The honey-fried preparation enhances its tonic and harmonizing properties.

Potential Drug Interactions

Si Jun Zi Tang contains Ren Shen (ginseng), which has known effects on platelet aggregation, blood glucose regulation, and certain hepatic enzyme pathways, and Zhi Gan Cao (licorice), which can affect cortisol metabolism and potassium levels with prolonged use. Pets on anticoagulant, antidiabetic, immunosuppressive, or corticosteroid medications should use this formula under veterinary supervision, as Ren Shen's mild platelet-affecting and blood glucose-modulating properties may have additive or counteracting effects with pharmaceutical agents in those categories, and herb-drug interaction research in dogs, cats, and horses remains limited.

Medication categories warranting extra caution include anticoagulant or antiplatelet medications, antidiabetic medications and insulin, corticosteroids and immunosuppressive drugs, diuretics and cardiac medications where Zhi Gan Cao's potassium effects may be relevant, and antihypertensive medications where Ren Shen's adaptogenic effects on blood pressure may interact. Your authorizing veterinarian can determine appropriateness based on your animal's condition, current medications, and laboratory results.

Frequently Asked Questions

What conditions is Si Jun Zi Tang used for in TCVM?

In Traditional Chinese Veterinary Medicine, Si Jun Zi Tang is indicated for spleen qi vacuity, presenting with fatigue and low energy, reduced appetite, soft or loose stool, muscle weakness or atrophy, poor body condition, and the general signs of insufficient qi failing to power the spleen's transformation and transportation functions and the body's overall vitality. Comparable to Four Gentlemen Powder and Wei Qi Booster, it is the foundational qi tonification formula from which many important TCVM formulas are derived, including Liu Jun Zi Tang, which adds dampness-resolving herbs for spleen qi deficiency with concurrent phlegm and dampness, and Ba Zhen Tang, which combines Si Jun Zi Tang with Si Wu San to address simultaneous qi and blood deficiency.

How is Si Jun Zi Tang administered to dogs, cats, and horses?

Mix the powder directly into food or grain at the dose recommended for your animal's species and body weight. 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. If the horse initially refuses, start with a small amount mixed into grain and gradually increase until the horse is accustomed to the taste. Most horses will readily accept the herbs in their grain. Your authorizing veterinarian will confirm the appropriate dose and schedule for your individual animal.

How long does it take to see results with Si Jun Zi Tang?

Many pets show improvement in energy, appetite, and stool consistency within 3 to 6 weeks of consistent use as the spleen qi is tonified and the spleen's transformation and transportation functions are restored. Because spleen qi deficiency is typically a chronic deficiency pattern that has developed gradually over time, a longer course of treatment of 8 to 12 weeks or more is often needed to adequately restore the qi and maintain improvement in vitality, digestive function, and muscle condition. Your veterinarian may recommend periodic reassessment to evaluate the pattern's response and adjust the treatment plan as the spleen qi is gradually rebuilt.

How does Si Jun Zi Tang relate to other qi-tonifying TCVM formulas?

Si Jun Zi Tang is the foundational four-herb qi tonification formula from which many related TCVM formulas are derived. Liu Jun Zi Tang adds Chen Pi and Ban Xia to the Si Jun Zi Tang base to address concurrent phlegm and dampness accumulation alongside the spleen qi deficiency. Ba Zhen Tang combines Si Jun Zi Tang with the four blood-nourishing herbs of Si Wu San to address simultaneous qi and blood deficiency. Shi Quan Da Bu Tang adds qi- and yang-warming herbs to the Ba Zhen Tang base for more severe combined deficiency patterns. Your authorizing veterinarian will determine which qi-tonifying formula best matches your animal's full TCVM pattern diagnosis based on whether the qi deficiency is accompanied by dampness, blood deficiency, yang deficiency, or other concurrent patterns.
