Recommended by holistic veterinarians, Jing Tang Equine GI Formula (Ma Wei Chang He) is a Traditional Chinese Veterinary Medicine (TCVM) herbal formula that dispels Dampness, strengthens Spleen Qi, and moves Stomach Qi downward to address patterns of Spleen Qi deficiency with Damp accumulation and Stomach Qi stagnation in horses. A modified Ping Wei San from Tai Ping Hui Min He Ji Ju Fang (Imperial Grace Formulary of the Tai Ping Era, 1080), written by Chen Shi-Wen et al., this nine-herb formula expands the classical Ping Wei San's Damp-drying and Stomach Qi-descending framework by adding Heat-clearing herbs (Huang Qin, Lian Qiao), a food stagnation-resolving herb (Shan Zha), a Spleen Qi-tonifying and Yin-nourishing herb (Shan Yao), and a stronger Qi-moving herb (Zhi Shi) alongside the classical core of Cang Zhu, Hou Po, Chen Pi, and Qing Pi. Available in concentrated powder and 600g standard powder. No contraindications and no warnings are listed for this formula. May be used as needed for up to 6 months, or as directed by your veterinarian. Dosing varies by species and body weight; your authorizing veterinarian will provide specific guidance.

Equine GI Formula is a nine-herb modified Ping Wei San organized around a Damp-drying and Spleen-strengthening layer (Cang Zhu, Shan Yao), a Stomach Qi-descending and Qi-moving layer (Hou Po, Chen Pi, Qing Pi, Zhi Shi), and a Heat-clearing, food stagnation-resolving, and toxin-dispersing layer (Huang Qin, Lian Qiao, Shan Zha):
Equine GI Formula contains Damp-drying and Qi-moving herbs including Cang Zhu (black atractylodes rhizome), Hou Po (magnolia bark), Chen Pi (aged tangerine peel), Qing Pi (green tangerine peel), and Zhi Shi (immature bitter orange fruit), Heat-clearing herbs including Huang Qin (scutellaria root) and Lian Qiao (forsythia fruit), a food stagnation-resolving herb Shan Zha (hawthorn fruit), and a Spleen Qi-tonifying herb Shan Yao (Chinese yam rhizome). Zhi Shi contains synephrine and may interact with cardiovascular medications and stimulants; Shan Zha may affect platelet function; Huang Qin may interact with anticoagulants and immunosuppressive medications. No contraindications and no warnings are listed for this formula. Horses on prescription medications should use this formula under veterinary supervision, as herb-drug interaction research in horses remains limited.
Medication categories warranting extra caution include cardiovascular medications, anticoagulant or antiplatelet medications, immunosuppressive medications, and horses managing multiple concurrent prescriptions. May be used as needed for up to 6 months, or as directed by your veterinarian. Your veterinarian can determine appropriateness based on your horse's condition, current medications, and laboratory results.

Equine GI Formula is indicated primarily for horses with TCVM patterns of Spleen Qi deficiency with Damp accumulation and Stomach Qi stagnation, where insufficient Spleen Qi has impaired the Spleen's transforming and transporting functions, leading to Dampness accumulating in the GI tract, Stomach Qi failing to descend, and food stagnation contributing to the signs of equine GI Damp and stagnation patterns. Holistic veterinarians frequently prescribe it as a foundational equine GI support formula for Damp-Spleen and Stomach Qi stagnation patterns. No contraindications and no warnings are listed for this formula. Your authorizing veterinarian will confirm the appropriate TCVM pattern diagnosis before recommending Equine GI Formula.
Dosing varies by species and body weight; your authorizing veterinarian will provide specific guidance. For horses using the 90g concentrated powder, the standard dose is 3g (approximately 2.5 large scoops) twice daily, or as directed by your veterinarian; the large scoop holds approximately 1.2g and the small scoop holds approximately 0.3g. For dogs and cats using the 90g concentrated powder, the dose is 0.1g to 0.25g per 10 to 20 lbs of body weight twice daily, or as directed by your veterinarian. For the 600g standard powder, your authorizing veterinarian will provide species-specific dosing guidance. May be used as needed for up to 6 months, or as directed by your veterinarian.
Ping Wei San (Calm the Stomach Powder) is one of the most foundational Damp-drying and Stomach Qi-moving formulas in Chinese medicine, first recorded in Tai Ping Hui Min He Ji Ju Fang (1080). The classical formula uses Cang Zhu, Hou Po, Chen Pi, and Gan Cao to dry Dampness, move Qi, harmonize the Stomach, and address Spleen Damp-Cold patterns affecting digestion and GI motility. Jing Tang's Equine GI Formula (Ma Wei Chang He) is a TCVM modification of Ping Wei San that extends the classical framework for equine GI patterns by adding Qing Pi (Liver Qi-moving) and Zhi Shi (stronger Qi-breaking) to address deeper Qi stagnation, Huang Qin and Lian Qiao to clear the Damp-Heat component common in equine GI patterns, Shan Zha to resolve food stagnation and support GI motility, and Shan Yao to tonify Spleen Qi and provide balancing moisture alongside the formula's drying herbs. These modifications adapt the classical Ping Wei San framework specifically to the Damp, Heat, stagnation, and Spleen Qi deficiency patterns typical in equine GI presentations.
The inclusion of Heat-clearing herbs (Huang Qin, Lian Qiao) alongside Damp-drying herbs (Cang Zhu, Hou Po, Chen Pi) reflects the clinical reality that equine GI patterns frequently present as Damp-Heat rather than pure Damp-Cold. In classical Ping Wei San, the formula is primarily warming and drying, suited to Spleen Damp-Cold patterns. In equine GI presentations, however, accumulated Dampness often generates or combines with Heat in the GI tract, producing a Damp-Heat pattern where pure warming and drying herbs would be insufficient or potentially aggravating. By adding Huang Qin and Lian Qiao to clear the Damp-Heat component while retaining the Damp-drying and Qi-moving core of Ping Wei San, Equine GI Formula addresses the combined Damp and Heat pattern common in horse GI presentations, making it more broadly applicable to the range of equine GI Damp patterns seen in TCVM practice.
