Herbsmith Rx Yi Guan Jian is a classical Chinese herbal formula recommended by holistic veterinarians to support liver and kidney yin and promote the smooth flow of liver qi in dogs, cats, and horses. Based on the traditional formula Yi Guan Jian (also known as Linking Powder, Gracious Power, and Glehnia and Rehmannia Combination), it enriches the yin and spreads the liver qi. It is well suited for pets presenting with liver and kidney yin vacuity combined with liver qi stagnation, showing signs such as dry coat, thirst, restlessness, flank tension or sensitivity, digestive irregularity, or a wiry and thin pulse. 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 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.

Yi Guan Jian is elegantly structured with five yin-nourishing herbs and a single qi-moving herb, making it uniquely suited for the complex pattern of yin deficiency with concurrent liver qi stagnation:
Yi Guan Jian contains yin-nourishing and blood-tonifying herbs including Sheng Di Huang, Dang Gui, and Gou Qi Zi, alongside the qi-moving herb Chuan Lian Zi. 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 anticoagulant or antiplatelet medications, hepatic medications or drugs metabolized by the liver, immunosuppressive drugs, and pets managing multiple concurrent prescriptions. Your authorizing veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

In Traditional Chinese Veterinary Medicine, Yi Guan Jian is indicated for the combined pattern of liver and kidney yin vacuity with liver qi stagnation, presenting as dry coat, thirst, restlessness, flank tension or sensitivity, digestive irregularity, and a wiry, thin pulse. It is a good alternative to Linking Powder, Gracious Power, and Glehnia and Rehmannia Combination, and is particularly appropriate for pets whose liver qi stagnation arises from an underlying yin deficiency rather than from excess constraint alone.
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.
As a yin-nourishing formula addressing a constitutional deficiency pattern, Yi Guan Jian works gradually over time. Many pets show improvement in coat moisture, thirst, restlessness, and digestive regularity within 4 to 8 weeks of consistent use. Chronic or deeply rooted liver and kidney yin vacuity patterns may require a longer course of treatment, and your veterinarian may recommend periodic reassessment to adjust the formula or dosing as your pet responds.
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 Chuan Lian Zi, which is processed by the liver, veterinary oversight is especially important if your pet is on hepatic medications or drugs with significant liver metabolism, to ensure the treatment plan fits your pet's overall health status.
