Recommended by holistic veterinarians, Jing Tang Wei Ling San is a Traditional Chinese Veterinary Medicine (TCVM) formula that tonifies Spleen Qi, dries Damp, and stops diarrhea to support gastrointestinal health in dogs, cats, and horses. A combination of the classical Ping Wei San and Wu Ling San, this ten-herb formula addresses both the root and branch of Spleen Qi deficiency with Damp accumulation, simultaneously strengthening the Spleen's transforming function and draining the pathological Dampness that causes diarrhea and digestive upset. Available in standard powder and capsules. Dosing varies by species, body weight, and health condition; your authorizing veterinarian will determine the appropriate dose following a TCVM evaluation.

Active Ingredient TCVM Actions
Wei Ling San combines the Spleen-strengthening and Damp-drying herbs of Ping Wei San with the Damp-draining and fluid-metabolizing herbs of Wu Ling San to address both the root Spleen Qi deficiency and the Damp accumulation causing diarrhea:
- Bai Zhu (Atractylodes macrocephala), White atractylodes rhizome: Strengthens the Spleen, dries Dampness, and supports the Spleen's ability to transform and transport fluids; a key Spleen-tonifying herb from the Ping Wei San base.
- Cang Zhu (Atractylodes lancea), Atractylodes rhizome: Strongly dries Dampness, strengthens the Spleen, and dispels Wind-Damp, addressing the Damp accumulation at the root.
- Hou Po (Magnolia officinalis), Magnolia bark: Moves Qi, dries Dampness, transforms phlegm, and descends rebellious Qi to relieve abdominal fullness and digestive obstruction.
- Chen Pi (Citrus reticulata), Tangerine peel: Regulates Qi, dries Dampness, and supports the Spleen and Stomach in moving Qi smoothly to prevent stagnation and Damp accumulation.
- Fu Ling (Poria cocos), Poria mushroom: Leaches out Dampness, strengthens the Spleen, and supports healthy fluid metabolism; a key Damp-draining herb from the Wu Ling San base.
- Ze Xie (Alisma orientalis), Water plantain rhizome: Drains Dampness through urination and clears Damp accumulation from the lower Jiao, the primary Damp-draining herb in Wu Ling San.
- Zhu Ling (Polyporus umbellatus), Polyporus mushroom: Drains Dampness, promotes urination, and supports healthy fluid metabolism alongside Ze Xie and Fu Ling.
- Gui Zhi (Cinnamomum cassia), Cinnamon twig: Warms the channels, unblocks Yang, and promotes the transformation and movement of fluids through the body, supporting the Damp-draining herbs.
- Gan Jiang (Zingiber officinale, dried), Dried ginger rhizome: Warms the Spleen and Stomach, transforms cold Damp, and supports Spleen Yang to prevent further Damp accumulation and stop diarrhea.
- Da Zao (Ziziphus jujuba), Jujube fruit: Tonifies Spleen and Stomach Qi, nourishes Blood, and harmonizes the actions of the other herbs.
Potential Drug Interactions
Wei Ling San contains Damp-drying and Spleen-tonifying herbs (Bai Zhu, Cang Zhu, Hou Po) alongside Damp-draining and fluid-metabolizing herbs (Ze Xie, Zhu Ling, Fu Ling) that may interact with certain medications. Pets 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 diuretic medications, gastrointestinal medications, and pets managing multiple concurrent prescriptions. Your veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

Frequently Asked Questions
What conditions is Wei Ling San used for in TCVM?
Wei Ling San is most commonly recommended for dogs, cats, and horses with TCVM patterns of Spleen Qi deficiency with Damp accumulation manifesting as chronic or recurrent diarrhea, loose stools, or digestive upset. Holistic veterinarians often prescribe it for pets whose underlying pattern involves a weakened Spleen failing to transform and transport fluids, leading to Damp accumulation in the gastrointestinal tract. The manufacturer lists no contraindications or warnings for this formula.
How is Wei Ling San administered, and what are the recommended doses?
Dosing varies by species, body weight, and health condition; your authorizing veterinarian will determine the appropriate dose following a TCVM evaluation. For dogs and cats, the general guideline is 0.5g per 10 to 20 lbs of body weight twice daily, administered as powder mixed into food or as capsules. For horses, the standard dose is 10 to 20g twice daily as a top dressing on feed. The 600g powder jar includes a double-sided scoop; the large scoop holds approximately 7g, and the small scoop holds approximately 2g.
How long does it take to see results with Wei Ling San?
Response time varies depending on the individual pet, the severity of the Spleen Qi deficiency and Damp pattern, and the format used. Many pet owners begin to notice improvements in stool consistency, digestive comfort, and appetite within 1 to 3 weeks of consistent use. The manufacturer recommends use as needed for up to 3 months. Regular follow-up with your holistic veterinarian is recommended to monitor progress and adjust dosing as needed.
Can Wei Ling San be combined with other TCVM formulas or medications?
Wei Ling San is sometimes used alongside other TCVM formulas as part of a comprehensive digestive support protocol, but your authorizing veterinarian should always guide combination use. If your pet is on prescription medications, particularly diuretics or gastrointestinal medications, your veterinarian will evaluate whether Wei Ling San is appropriate given your pet's full health picture and current treatment plan. The manufacturer lists no contraindications or warnings for this formula.
