Herbsmith Rx Shen Qi Da Bu San is a classical Chinese herbal formula recommended by holistic veterinarians as a broad-spectrum tonic for qi, blood, ying qi, and wei qi in dogs, cats, and horses. Comparable to Ginseng Astragalus Great Tonifying Powder, Big Tonic Teapills, and General Tonic Formula, it tonifies the qi, nourishes the blood, and strengthens the ying and wei qi, addressing general debilitation, fatigue, poor digestion due to spleen and stomach deficiency, and blood deficiency, while supporting the immune response through Huang Qi's wei qi-strengthening action. A two-herb formula with a broad tonic scope, combining the spleen and lung qi-tonifying and blood-nourishing action of Dang Shen with the spleen and lung qi-tonifying, yang-raising, and wei qi-strengthening action of Huang Qi to address the full range of qi, blood, ying, and wei qi deficiency patterns that present as general fatigue, debilitation, poor appetite, digestive weakness, and reduced immune vitality. Well suited for pets and horses recovering from illness or surgery, aging animals with general qi and blood deficiency, and animals with chronic spleen and stomach deficiency presenting with fatigue, poor appetite, loose stools, and reduced vitality. 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.

Shen Qi Da Bu San is a two-herb formula combining two of the most important qi tonics in the Chinese materia medica to provide broad qi, blood, ying, and wei qi tonification through complementary and mutually reinforcing actions:
Shen Qi Da Bu San contains Huang Qi (Astragalus), which has well-documented immunomodulatory activity and may interact with immunosuppressive medications by counteracting their intended effect. Animals on cyclosporine, corticosteroids, or other immunosuppressive pharmaceuticals should use this formula only under close veterinary supervision, as Huang Qi's immune-activating action may reduce the efficacy of immunosuppression in animals being treated for immune-mediated diseases, organ transplant support, or conditions requiring controlled immune activity. Dang Shen may also have mild effects on blood glucose regulation, warranting monitoring in animals on antidiabetic medications.
Medication categories warranting extra caution include immunosuppressive medications and corticosteroids (where Huang Qi's immune-activating effects may be clinically significant), antidiabetic medications and insulin, anticoagulant and antiplatelet medications, and any pharmaceutical where immune function or blood glucose stability is an active clinical concern. Your authorizing veterinarian will determine appropriateness based on your animal's condition, current medications, and laboratory results.

In Traditional Chinese Veterinary Medicine, Shen Qi Da Bu San is indicated as a broad-spectrum general tonic for animals presenting with qi, blood, ying qi, and wei qi deficiency, including general debilitation, fatigue, poor appetite, digestive weakness due to spleen and stomach deficiency, blood deficiency, and reduced immune vitality. Comparable to Ginseng Astragalus Great Tonifying Powder, Big Tonic Teapills, and General Tonic Formula, it is particularly well suited for aging animals with generalized qi and blood deficiency, animals recovering from illness or surgery, and animals with chronic spleen and stomach deficiency presenting with fatigue, loose stools, and reduced resilience to repeated infections.
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 based on your animal's individual pattern and current health status.
Many pets show improvement in energy, appetite, digestion, and general vitality within 4 to 8 weeks of consistent use as the qi and blood are progressively tonified and the spleen and stomach function is restored. Because general debilitation and chronic qi and blood deficiency typically reflect longstanding deficiency patterns rather than acute conditions, a longer course of treatment of 3 to 6 months or more is often needed to fully restore qi and blood levels, stabilize the immune response through sustained wei qi tonification, and maintain the improvement in vitality, digestion, and resilience over time. Your veterinarian will reassess the pattern periodically as the formula takes effect.
Shen Qi Da Bu San is designed as a broad-spectrum general tonic that addresses the full scope of qi, blood, ying qi, and wei qi deficiency simultaneously, making it distinct from more targeted qi tonic formulas that address specific organ systems or patterns. Si Jun Zi Tang, for example, focuses on spleen and stomach qi deficiency without the wei qi-strengthening component; Ba Zhen Tang adds blood tonification through a fuller eight-herb formula; and more specific formulas address lung qi deficiency, kidney qi deficiency, or wei qi deficiency individually. Shen Qi Da Bu San's two-herb composition provides broad tonic coverage with a lower herb-drug interaction profile than more complex formulas, making it appropriate when a comprehensive but well-tolerated general tonic is needed. Your authorizing veterinarian will determine which qi tonic formula best matches your animal's specific TCVM pattern.
