Available in a 90g Concentrated Powder, 0.5g Concentrated Capsules (100 count), and Teapills (200 count). Contraindicated in Yin deficiency. Use for up to 6 months.

Bu Zhong Yi Qi Tang is an eight-herb formula centered on two primary Yang-raising herbs (Chai Hu and Sheng Ma) combined with the four major Qi-tonifying herbs of the Middle Jiao to create Li Dong-yuan's signature formula for Spleen Qi deficiency with sunken Middle Jiao Yang:
Bu Zhong Yi Qi Tang contains potent Qi-tonifying herbs (Huang Qi, Ren Shen, Bai Zhu, Gan Cao), Yang-raising herbs (Chai Hu, Sheng Ma), a Qi-moving herb (Chen Pi), and a Blood-nourishing herb (Dang Gui) that may interact with certain medications. Ren Shen (Ginseng) has documented interactions with anticoagulant, antidiabetic, and certain cardiovascular medications. Gan Cao (Licorice root) may interact with diuretic and antihypertensive medications with long-term use. Contraindicated in Yin deficiency. Pets on prescription medications should use this formula under veterinary supervision, as herb-drug interaction research in dogs, cats, and horses remains limited.
Medication categories warranting extra caution include anticoagulant or antiplatelet medications, antidiabetic medications, cardiovascular medications, diuretic medications (with long-term Gan Cao use), immunosuppressive medications, and multiple concurrent prescription medications. Use for up to 6 months, or as directed by your veterinarian. Your veterinarian can determine appropriateness based on the patient's condition, medications, and laboratory results.

Bu Zhong Yi Qi Tang is used in TCVM for Spleen and Stomach Qi deficiency with sunken Middle Jiao Yang - one of the most important and clinically common deficiency patterns in TCVM practice. Signs of this pattern in animals may include fatigue, weakness, poor appetite, loose stool, muscle atrophy, organ prolapse or descent (such as rectal prolapse, uterine prolapse, or bladder prolapse), and the general signs of Qi deficiency with reduced Middle Jiao holding and lifting function. Contraindicated in Yin deficiency, as the formula's Yang-raising and Qi-tonifying herbs can exacerbate internal Heat and Yin depletion in Yin-deficient patients. Your veterinarian will assess your pet's TCVM pattern to confirm this formula is appropriate.
For horses, give 3g (2.5 large scoops) of concentrated powder twice daily, or as directed by your veterinarian. For dogs and cats using the 90g Concentrated Powder, give 0.1g to 0.25g per 10 to 20 lb body weight twice daily; the small scoop holds approximately 0.3g. For the 0.5g Concentrated Capsule format, give one capsule per 20 to 40 lb body weight twice daily; for small dogs and cats under 10 lbs, give one 0.2g concentrated capsule once daily, or as directed by your veterinarian. Teapills can be hidden in food or a soft treat. Use for up to 6 months, or as directed by your veterinarian.
Bu Zhong Yi Qi Tang originates from Pi Wei Lun (Discussion of the Spleen and Stomach), written by Li Dong-yuan in 1249 during the Jin dynasty. Li Dong-yuan, also known as Li Gao or Li Ao, was one of the Four Great Masters of the Jin-Yuan era and the founder of the Earth School (Tu Pai) of Chinese medicine - a school that placed the Spleen and Stomach at the center of health and longevity. His core thesis was that most disease originates from injury to the Spleen and Stomach Qi, and his formulation of Bu Zhong Yi Qi Tang - literally Tonify the Middle and Augment the Qi Decoction - embodies this philosophy. The formula has been in continuous clinical use for nearly eight centuries and remains one of the most prescribed classical formulas in both human and veterinary TCVM practice. Its inclusion of Chai Hu and Sheng Ma as Yang-raising herbs alongside the standard Middle Jiao tonics is Li Dong-yuan's most distinctive contribution to Chinese medicine.
Bu Zhong Yi Qi Tang contains several potent Yang-raising and Qi-tonifying herbs - particularly Huang Qi, Ren Shen, Sheng Ma, and Chai Hu - that are highly effective for Spleen Qi deficiency with sunken Yang but can worsen internal Heat and Yin depletion in patients with underlying Yin deficiency. In TCVM, Yin deficiency generates internal Heat when the cooling, moistening Yin is insufficient to balance and anchor Yang energy. Raising Yang further in a Yin-deficient patient can exacerbate the internal Heat, deplete Yin more rapidly, and worsen signs such as restlessness, panting, polydipsia, and heat intolerance. This formula is most appropriate for patients with clear Spleen Qi deficiency and sunken Yang without significant Yin deficiency. Your veterinarian will assess your pet's constitutional pattern to determine whether Bu Zhong Yi Qi Tang or a modified approach is most appropriate.
