Herbsmith Rx Ren Shen Yang Ying San is a classical Chinese herbal formula recommended by holistic veterinarians to augment the qi, tonify the blood, nourish the heart, and calm the spirit in dogs, cats, and horses. Comparable to Ginseng Decoction to Nourish the Nutritive Qi, Ginseng and Rehmannia Combination, and Ginseng Nourishing Formula, it augments the qi, tonifies the blood, nourishes the heart, and calms the spirit, addressing profound deficiency of both qi and blood with concurrent heart-spirit insufficiency. One of the most comprehensive qi and blood tonic formulas in the classical repertoire, built on the Ba Zhen Tang qi-and-blood-tonifying foundation with five additional herbs that strongly augment the wei qi, warm the yang to promote blood circulation, move qi to prevent tonic stagnation, astringe the lung and heart qi, and open the heart orifices to settle the spirit. Well suited for pets and horses presenting with the combined qi and blood deficiency and heart spirit insufficiency pattern, characterized by profound fatigue, pallor or pale mucous membranes, poor appetite, weight loss, forgetfulness, palpitations, restless or poor sleep, and a pale tongue with a thin white coating and a thin or frail pulse reflecting the deep qi and blood deficiency underlying the pattern. Also a primary formula for recovery from chronic illness, prolonged deficiency states, or post-surgical and post-illness convalescence where both qi and blood have been significantly depleted. 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.

Ren Shen Yang Ying San is a twelve-herb formula built on the Ba Zhen Tang comprehensive qi-and-blood-tonifying foundation, extended with five additional herbs that strongly augment the wei qi, warm the yang, move qi, astringe the spirit, and settle the heart orifices to address all dimensions of the profound qi and blood deficiency with heart spirit insufficiency pattern:
Ren Shen Yang Ying San contains Ren Shen (ginseng) and Huang Qi, which affect platelet aggregation, blood glucose regulation, immune modulation, and certain hepatic enzyme pathways, making anticoagulant, antidiabetic, immunosuppressive, and hepatically metabolized drug interactions the primary clinical concerns. Yuan Zhi has documented neurological activity and may interact with sedative, anxiolytic, or centrally acting medications. Rou Gui has mild anticoagulant and blood-moving properties that add to the formula's overall anticoagulant interaction profile. Pets on cardiac medications, antidiabetic medications, anticoagulant medications, immunosuppressive medications, sedatives, or neurologically active pharmaceuticals should use this formula under veterinary supervision, and herb-drug interaction research in dogs, cats, and horses remains limited.
Medication categories warranting extra caution include anticoagulant and antiplatelet medications (Ren Shen, Huang Qi, and Rou Gui's combined effects on platelet aggregation and blood movement), antidiabetic medications and insulin (Ren Shen's and Huang Qi's blood glucose effects), immunosuppressive medications (Huang Qi's immune-modulating action), sedative and anxiolytic medications (Yuan Zhi's neurological activity and Wu Wei Zi's calming effects), cardiac medications, and hepatically metabolized pharmaceuticals. Your authorizing veterinarian will determine appropriateness based on your animal's condition, current medications, and laboratory results.

In Traditional Chinese Veterinary Medicine, Ren Shen Yang Ying San is indicated for profound deficiency of both qi and blood with concurrent heart spirit insufficiency, presenting as extreme fatigue, pallor or pale mucous membranes, poor appetite, weight loss, palpitations, forgetfulness, restless or poor sleep, and a pale tongue with a thin white coating and thin or frail pulse. Comparable to Ginseng Decoction to Nourish the Nutritive Qi, Ginseng and Rehmannia Combination, and Ginseng Nourishing Formula, it is one of the most comprehensive classical formulas for the combined qi-blood-spirit deficiency pattern, and is a primary formula for convalescent support following chronic illness, prolonged deficiency states, or post-surgical or post-illness recovery where both qi and blood have been significantly depleted.
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 review the full medication list, given the formula's multiple herbs with anticoagulant, antidiabetic, and immune-modulating effects.
Because Ren Shen Yang Ying San addresses profound and often longstanding qi and blood deficiency, improvement in energy, appetite, and coat or muscle condition typically becomes noticeable within 4 to 8 weeks of consistent use as the qi and blood are progressively rebuilt. Improvement in spirit-related signs such as sleep quality, calmness, and cognitive clarity may appear within 3 to 6 weeks as Yuan Zhi and Wu Wei Zi nourish the heart spirit and open the orifices. Because the profound deficiency underlying the pattern is typically established over months or years, a treatment course of 3 to 6 months or more is often needed to fully restore the qi and blood and maintain constitutional strength over time. Your veterinarian will monitor body condition, coat quality, mucous membrane color, and pulse quality as indicators of the progressive restoration of qi and blood.
Ren Shen Yang Ying San, Ba Zhen Tang, and Shi Quan Da Bu Tang all address combined qi and blood deficiency, but differ in their additional herbs and specific emphasis. Ba Zhen Tang (Si Jun Zi Tang plus Si Wu Tang) is the foundational qi-and-blood tonic without additional specialization. Shi Quan Da Bu Tang adds Huang Qi and Rou Gui to Ba Zhen Tang to address wei qi deficiency and yang deficiency alongside the qi and blood. Ren Shen Yang Ying San similarly adds Huang Qi and Rou Gui, but further adds Wu Wei Zi, Yuan Zhi, and Chen Pi to specifically address heart spirit insufficiency and the risk of tonic stagnation in the middle jiao, making it the most appropriate choice when palpitations, forgetfulness, and restless sleep indicate significant heart spirit involvement alongside the qi and blood deficiency. Your authorizing veterinarian will determine which formula best matches your animal's specific pattern.
