Herbsmith Rx Tian Wang Bu Xin Wan is a classical Chinese herbal formula recommended by holistic veterinarians to nourish the heart, calm the spirit, and support restful behavior in dogs, cats, and horses.

Well suited for pets presenting with restlessness, anxiety, disturbed sleep, mental fatigue, excessive vocalization, and other signs of heart yin vacuity and heart-kidney disharmony, arising from heart blood and kidney yin deficiency, allowing deficiency fire to disturb the shen, with signs such as restlessness, startling easily, night-time wakefulness, and a restless or unsettled demeanor. 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.

Tian Wang Bu Xin Wan is a 12-herb formula that comprehensively addresses heart blood and kidney yin vacuity with deficiency fire disturbing the shen, combining yin-enriching, blood-nourishing, shen-calming, and directing herbs to restore the heart-kidney communication and anchor the spirit:
Tian Wang Bu Xin Wan contains yin-nourishing, blood-moving, and qi-tonifying herbs, including Ren Shen, Dan Shen, and Dang Gui, which significantly affect cardiac function, platelet aggregation, and drug metabolism. Ren Shen and Dan Shen in particular warrant close veterinary monitoring in pets on cardiac medications, sedatives, or anticoagulant therapies, as these herbs can influence heart rate, blood pressure, platelet function, and the metabolism of certain drugs. Pets currently 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 cardiac medications, sedative or anxiolytic medications, anticoagulant or antiplatelet medications, monoamine oxidase inhibitors, and pets managing concurrent behavioral or neurological conditions under pharmaceutical protocols. Your authorizing veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

In Traditional Chinese Veterinary Medicine, Tian Wang Bu Xin Wan is indicated for heart blood and kidney yin vacuity with deficiency fire disturbing the shen, presenting as restlessness, anxiety, disturbed sleep, night-time wakefulness, excessive vocalization, startling easily, and mental fatigue. Comparable to Emperor of Heaven Tonify the Heart, Shen Calmer, Celestial Emperor's Blend, Heavenly Emperor's Formula, and Ginseng and Zizyphus Formula, it is one of the most important classical formulas for addressing shen disturbance arising from the heart-kidney disharmony pattern, and is appropriate for pets whose behavioral presentations reflect an underlying yin and blood deficiency rather than an excess or heat pattern.
Mix the powder directly into food or grain at the dose recommended for your pet's species and body weight. Both 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. Your authorizing veterinarian will confirm the appropriate dose and schedule for your individual pet and advise whether concurrent behavioral support or environmental modifications are appropriate alongside this formula.
Because it works by building yin and blood over time, Tian Wang Bu Xin Wan is a gradual tonic rather than a fast-acting formula, and most pets show improvement in restlessness, sleep quality, and settled behavior after 4 to 8 weeks of consistent use. Deeply established yin and blood deficiency patterns, particularly in older pets, may require a longer course of treatment, and your veterinarian may recommend periodic reassessment to evaluate the formula's effectiveness and adjust the treatment plan as your pet's shen stabilizes.
Combination with complementary TCVM formulas is common in holistic veterinary practice and should be guided by your authorizing veterinarian based on your pet's full pattern diagnosis. Because this formula contains Ren Shen, which can influence cardiac function and drug metabolism, and Dan Shen, which has known antiplatelet and cardiac effects, veterinary oversight is especially important if your pet is on cardiac medications, sedatives, anxiolytic medications, or anticoagulant therapies, to monitor for additive effects and ensure the combined treatment plan is appropriate for your pet's overall health status.
