Recommended by holistic veterinarians, Jing Tang Four Immortals is a Traditional Chinese Veterinary Medicine (TCVM) herbal formula that warms and tonifies Kidney and Spleen Yang to address patterns of Kidney Yang deficiency and Spleen Yang deficiency in dogs, cats, and horses. Based on Si Shen Wan from Zheng Zhi Zhun Sheng (Standards of Patterns and Treatments, 1602), written by Wang Ken-Tang, this six-herb classical formula warms the Kidney and Spleen Yang, consolidates the intestines, and addresses the cold, deficient GI signs associated with Kidney and Spleen Yang deficiency, pairing the primary Kidney Yang-warming herb (Bu Gu Zhi) with a Liver and Stomach-warming and Qi-descending herb (Wu Zhu Yu), an astringent Qi-consolidating herb (Rou Dou Kou), a warming middle-Jiao herb (Gan Jiang), a Qi- and Yin-consolidating herb (Wu Wei Zi), and a Spleen-supporting and harmonizing herb (Da Zao). Available in concentrated powder and concentrated capsules. Dosing varies by species and body weight; your authorizing veterinarian will provide specific guidance.

Four Immortals is a six-herb classical formula organized around a primary Kidney Yang-warming herb (Bu Gu Zhi), a Liver and Stomach-warming and Qi-descending herb (Wu Zhu Yu), a Spleen and Stomach-warming and astringent herb (Rou Dou Kou), a middle-Jiao-warming herb (Gan Jiang), a Qi- and Yin-consolidating herb (Wu Wei Zi), and a Spleen-supporting and harmonizing herb (Da Zao):
Four Immortals contains warming Yang-tonifying herbs including Bu Gu Zhi (psoralea fruit), Wu Zhu Yu (evodia fruit), Rou Dou Kou (nutmeg seed), and Gan Jiang (dried ginger rhizome), alongside an astringent herb Wu Wei Zi (schisandra fruit) known to affect cytochrome P450 enzyme activity and drug metabolism, and a harmonizing herb Da Zao (jujube fruit). The warming, Yang-tonifying nature of this formula may be inappropriate for patients with concurrent Heat or Yin deficiency patterns. 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, medications metabolized by cytochrome P450 enzymes, and pets managing multiple concurrent prescriptions. No contraindications and no specific warnings are listed for this formula. Your veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

Four Immortals is indicated for dogs, cats, and horses with TCVM patterns of Kidney Yang deficiency and Spleen Yang deficiency, where the Kidney Yang's failure to warm the Spleen has led to cold, deficient GI patterns and the constitutional signs associated with Kidney and Spleen Yang deficiency. Holistic veterinarians frequently prescribe it for patients presenting with cold, deficient GI signs rooted in Kidney and Spleen Yang deficiency. No contraindications and no specific warnings are listed for this formula. Your authorizing veterinarian will confirm the appropriate TCVM pattern diagnosis before recommending Four Immortals.
Dosing varies by species and body weight; your authorizing veterinarian will provide specific guidance. For the 90g concentrated powder, the dose for dogs and cats is 0.1g to 0.25g per 10 to 20 lbs of body weight twice daily, or as directed by your veterinarian; the small scoop holds approximately 0.25g, and the large scoop holds approximately 1.2g. For horses, the standard dose is 3g (approximately 2.5 large scoops) twice daily, or as directed by your veterinarian. For 0.5g concentrated capsules, the guideline is one capsule per 20 to 40 lbs of body weight twice daily, or as directed by your veterinarian. For small dogs and cats under 10 lbs, one 0.2g capsule once daily when that format is available, or as directed by your veterinarian. Your authorizing veterinarian will confirm the appropriate dose and duration for your pet.
Si Shen Wan (Four Miracle Pill) is one of the most important classical formulas in Chinese medicine for Kidney and Spleen Yang deficiency patterns presenting with cold, deficient GI signs, particularly early morning cold diarrhea associated with Kidney Yang's failure to warm the Spleen and Stomach. First recorded in Zheng Zhi Zhun Sheng (1602) by Wang Ken-Tang, Si Shen Wan pairs the primary Kidney Yang-warming herb Bu Gu Zhi with the warming, astringent, and Spleen-supporting herbs Rou Dou Kou, Wu Zhu Yu, Wu Wei Zi, and Da Zao to address the root Kidney Yang deficiency and its downstream effects on Spleen Yang and GI function. Four Immortals incorporates Gan Jiang (dried ginger) as an additional middle-Jiao-warming herb, extending the classical formula's warming action to more directly address middle-Jiao Cold alongside the root Kidney Yang deficiency.
The combination of warming Yang-tonifying herbs (Bu Gu Zhi, Wu Zhu Yu, Gan Jiang) with astringent herbs (Rou Dou Kou, Wu Wei Zi) in Four Immortals reflects the classical Chinese medicine principle that Kidney and Spleen Yang deficiency GI patterns require two simultaneous therapeutic strategies: addressing the root Yang deficiency through warming and tonification, and addressing the immediate manifestation through astringent consolidation of the intestines. The warming herbs address the root cause (Kidney and Spleen Yang insufficiency) while the astringent herbs consolidate the leakage that results from Yang deficiency failing to hold and transform. Without the warming herbs, the astringent herbs would consolidate the leakage without addressing the underlying Yang deficiency; without the astringent herbs, the warming herbs would address the root but provide slower symptomatic relief. The combination of both strategies in one formula is the classical design of Si Shen Wan and the foundation of Four Immortals.
