Herbsmith Rx Shen Tong Zhu Yu Tang is a classical Chinese herbal formula recommended by holistic veterinarians to address musculoskeletal discomfort due to qi and blood stagnation blocking the channels and collaterals in dogs, cats, and horses. Comparable to Drive out Blood Stasis from a Painful Body Decoction, Body Sore, and The Great Invigorator Teapills, it addresses discomfort in the shoulder, elbow, waist, and leg, as well as persistent, generalized discomfort throughout the whole body arising from qi and blood stagnation blocking the channels and collaterals. One of the most comprehensive blood stasis-resolving and channel-opening formulas in the TCVM materia medica, combining blood-invigorating, qi-moving, wind-damp-expelling, and channel-guiding herbs to address the full scope of the bi syndrome pattern where blood stasis and qi stagnation are blocking the free flow of qi and blood through the channels and collaterals. Well suited for pets and horses presenting with fixed, persistent musculoskeletal discomfort that worsens with pressure and is not relieved by rest, located in the shoulders, elbows, lower back, hips, and limbs, with a purple or dusky tongue and a choppy or wiry pulse reflecting the blood stasis and qi stagnation underlying the pattern. 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.

For Dogs (Canine Blend Powder):
For Cats (Canine Blend Powder): ¼ tsp twice daily, or as prescribed
For Horses (Equine/Horse Blend, 1,000 lb horse): Two tablespoons twice daily for 20 days, then two tablespoons once daily in grain.

Shen Tong Zhu Yu Tang is a ten-herb formula addressing blood stasis bi syndrome with a concurrent wind-damp component through three coordinated herb groups: a five-herb blood-invigorating and stasis-resolving group, a two-herb wind-damp-expelling group, and supporting qi-moving, channel-guiding, and harmonizing herbs:
Shen Tong Zhu Yu Tang contains five herbs with significant blood-invigorating and stasis-resolving properties (Tao Ren, Hong Hua, Dang Gui, Chuan Xiong, and Mo Yao), representing the highest concentration of blood-moving herbs in the Herbsmith Rx line and making anticoagulant and antiplatelet drug interactions the primary clinical concern for this formula. Pets currently on any anticoagulant, antiplatelet, or anti-inflammatory medication must have their full medication list reviewed by the authorizing veterinarian before initiating this formula, as the combined blood-invigorating action of five herbs with blood-moving properties represents a meaningful and cumulative interaction risk with blood-thinning pharmaceuticals, and herb-drug interaction research in dogs, cats, and horses remains limited.
Medication categories warranting extra caution include anticoagulant and antiplatelet medications (where the risk is highest due to the number of blood-moving herbs), non-steroidal anti-inflammatory drugs, cardiovascular medications, hepatically metabolized pharmaceuticals, immunosuppressive medications, and chemotherapy agents. Because of the number and potency of blood-invigorating herbs in this formula, veterinary review of the complete medication list and current laboratory values is essential before initiating treatment. Your authorizing veterinarian will determine appropriateness based on your animal's condition, medications, and laboratory results.

In Traditional Chinese Veterinary Medicine, Shen Tong Zhu Yu Tang is indicated for blood stasis bi syndrome with a concurrent wind-damp component, presenting with fixed, persistent musculoskeletal discomfort throughout the whole body, particularly in the shoulders, elbows, lower back, and legs, that worsens with pressure, does not improve with rest, and is accompanied by a purple or dusky tongue and choppy or wiry pulse reflecting the underlying blood stasis and qi stagnation. Comparable to Drive out Blood Stasis from a Painful Body Decoction, Body Sore, and The Great Invigorator Teapills, it is indicated when the musculoskeletal discomfort pattern has a fixed, blood stasis quality rather than the moving quality of wind-predominant bi syndrome, and when the discomfort is generalized and persistent rather than localized or episodic.
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 and will review the full medication list before starting this formula, given its multiple blood-invigorating herbs.
Many pets show improvement in comfort, mobility, and movement quality within 4 to 8 weeks of consistent use as the blood stasis is progressively resolved and the channels are reopened. Because blood stasis bi syndrome typically reflects a more established and deeply rooted obstruction than wind-predominant or cold-predominant bi syndrome, a longer course of treatment of 10 to 16 weeks or more is often needed to adequately resolve the blood stasis throughout the channels and collaterals and maintain improvement in mobility and comfort. Your veterinarian will monitor both the pattern's response and the animal's laboratory values throughout the treatment course.
Shen Tong Zhu Yu Tang is specifically formulated for the blood stasis bi syndrome pattern with generalized, whole-body involvement and a concurrent wind-damp component, distinguishing it from formulas that primarily address cold bi syndrome, wind-damp bi syndrome without blood stasis, or localized joint discomfort patterns. Its ten-herb composition with five blood-invigorating herbs and two wind-damp-expelling herbs makes it one of the most comprehensive channel-opening formulas available and appropriate when blood stasis is the predominant root of the musculoskeletal discomfort pattern. Your authorizing veterinarian will determine which musculoskeletal discomfort formula best matches your animal's TCVM pattern based on whether blood stasis, cold, wind-damp, qi deficiency, kidney deficiency, or other concurrent patterns are predominant.
