Named for its principal herb Du Zhong (eucommia bark), this twenty-five-herb formula addresses lower back and hindlimb weakness and stiffness from kidney qi, blood, and yang vacuity through a sophisticated multi-layer approach: a primary spleen and kidney tonification scaffold strengthens the root of qi, blood, yin, and essence production; a kidney yang and sinew-strengthening layer directly nourishes the lower back, lumbar spine, and hindlimb channels through Du Zhong, Rou Cong Rong, Ba Ji Tian, and Yin Yang Huo; three herbs (Jin Ying Zi, Nu Zhen Zi, Shan Zhu Yu) support kidney essence nourishment and retention; two spirit-calming herbs (Yuan Zhi and Bai Zi Ren) support the heart-kidney axis that kidney vacuity disrupts; and the classical restraining herbs Ze Xie, Mu Dan Pi, Chen Pi, and Sha Ren balance the heavy tonics with dampness-draining, heat-clearing, and qi-regulating actions. Well suited for dogs, cats, and horses presenting with kidney qi, blood, and yang vacuity, characterized by lower back weakness and stiffness, hindlimb weakness and reduced mobility, reduced exercise tolerance, a pale, moist, or slightly red tongue depending on the relative predominance of yang vacuity or blood-yin deficiency, and a deep, weak, or thin pulse in the kidney position. 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eVETERINARY AUTHORIZATION REQUIRED: \u003ca href=\"https:\/\/tcvmpet.com\/pages\/get-an-authorization\" rel=\"noopener\" style=\"color: rgb(0, 0, 0);\" target=\"_blank\"\u003eSubmit Your Authorization Request\u003c\/a\u003e or \u003ca href=\"https:\/\/tcvmpet.com\/pages\/schedule-a-consultation\" rel=\"noopener\" style=\"color: rgb(0, 0, 0);\" target=\"_blank\"\u003eRequest a TCVM Telemedicine Consultation\u003c\/a\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eWhat It Supports\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul style=\"text-align: left;\"\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eKidney qi, blood, and yang tonification through the primary spleen and kidney constitutional root scaffold:\u003c\/strong\u003e Tonifies the kidney qi, blood, and yang from the constitutional root using the high-dose primary scaffold of Dang Shen, Bai Zhu, Fu Ling, and Gan Cao (the Si Jun Zi Tang base for spleen qi to support kidney qi through the earth-nourishes-water relationship), Shu Di Huang (deep kidney yin, blood, and essence nourishment as the constitutional root of yang), Gou Qi Zi (liver and kidney yin and blood nourishment), and Shan Yao (spleen, lung, and kidney qi and yin). The spleen-strengthening herbs in this scaffold reflect the classical TCVM principle that the spleen (earth) is the post-natal root of qi and blood production, and that sustained kidney vacuity must be treated by strengthening the spleen's ability to generate qi and blood alongside direct kidney tonification.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eLower back, lumbar spine, and hindlimb sinew and bone strengthening through the kidney yang and essence tonification layer:\u003c\/strong\u003e Directly strengthens the lower back, lumbar spine, hindlimb channels, sinews, and bones through the combined kidney yang and essence-tonifying action of Du Zhong (the eponymous herb, kidney yang and liver tonification with specific affinity for the lumbar spine and lower limbs), Rou Cong Rong (kidney yang and essence tonification with specific affinity for the sinews and bone marrow), Ba Ji Tian (kidney yang tonification, sinew strengthening, and wind-cold-dampness expulsion from the channels), and Yin Yang Huo (the formula's most potent kidney yang tonic, strengthening the sinews and expelling wind-cold-dampness from the channels and lower limb joints).

The highest-dose group (Fu Ling, Bai Zhu, Shan Yao, Dang Shen, Gou Qi Zi, Huang Qi, and Shu Di Huang at 7.38% each) combines spleen and qi support with kidney yin, blood, and essence nourishment. In TCVM, the spleen is the post-natal root of qi and blood production; its transforming and distributing function supports the kidney-targeting tonics. This is why the formula combines a substantial spleen-supporting foundation with direct lower back and hindlimb-focused tonification rather than relying on warming yang tonics alone.\u003c\/span\u003e\u003c\/p\u003e","published_at":"2022-05-20T18:02:09-05:00","created_at":"2022-04-29T11:34:06-05:00","vendor":"Herbsmith Rx","type":"Pet Vitamins \u0026 Supplements","tags":["Herb_Type_Powder","Product_Type_Herb","Species_Cat","Species_Dog","Species_Horse","Vendor_Herbsmith_Rx"],"price":7000,"price_min":7000,"price_max":22200,"available":true,"price_varies":true,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":40021636087878,"title":"Powder -

Named for its principal herb Du Zhong (eucommia bark), this twenty-five-herb formula addresses lower back and hindlimb weakness and stiffness from kidney qi, blood, and yang vacuity through a sophisticated multi-layer approach: a primary spleen and kidney tonification scaffold strengthens the root of qi, blood, yin, and essence production; a kidney yang and sinew-strengthening layer directly nourishes the lower back, lumbar spine, and hindlimb channels through Du Zhong, Rou Cong Rong, Ba Ji Tian, and Yin Yang Huo; three herbs (Jin Ying Zi, Nu Zhen Zi, Shan Zhu Yu) support kidney essence nourishment and retention; two spirit-calming herbs (Yuan Zhi and Bai Zi Ren) support the heart-kidney axis that kidney vacuity disrupts; and the classical restraining herbs Ze Xie, Mu Dan Pi, Chen Pi, and Sha Ren balance the heavy tonics with dampness-draining, heat-clearing, and qi-regulating actions. Well suited for dogs, cats, and horses presenting with kidney qi, blood, and yang vacuity, characterized by lower back weakness and stiffness, hindlimb weakness and reduced mobility, reduced exercise tolerance, a pale, moist, or slightly red tongue depending on the relative predominance of yang vacuity or blood-yin deficiency, and a deep, weak, or thin pulse in the kidney position. 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eVETERINARY AUTHORIZATION REQUIRED: \u003ca href=\"https:\/\/tcvmpet.com\/pages\/get-an-authorization\" rel=\"noopener\" style=\"color: rgb(0, 0, 0);\" target=\"_blank\"\u003eSubmit Your Authorization Request\u003c\/a\u003e or \u003ca href=\"https:\/\/tcvmpet.com\/pages\/schedule-a-consultation\" rel=\"noopener\" style=\"color: rgb(0, 0, 0);\" target=\"_blank\"\u003eRequest a TCVM Telemedicine Consultation\u003c\/a\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eWhat It Supports\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul style=\"text-align: left;\"\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eKidney qi, blood, and yang tonification through the primary spleen and kidney constitutional root scaffold:\u003c\/strong\u003e Tonifies the kidney qi, blood, and yang from the constitutional root using the high-dose primary scaffold of Dang Shen, Bai Zhu, Fu Ling, and Gan Cao (the Si Jun Zi Tang base for spleen qi to support kidney qi through the earth-nourishes-water relationship), Shu Di Huang (deep kidney yin, blood, and essence nourishment as the constitutional root of yang), Gou Qi Zi (liver and kidney yin and blood nourishment), and Shan Yao (spleen, lung, and kidney qi and yin).

Kidney vacuity in TCVM typically disrupts the heart-kidney axis because the kidney water fails to rise and cool the heart fire, leading to heart spirit restlessness alongside the kidney vacuity constitutional weakness; Yuan Zhi and Bai Zi Ren address this secondary heart spirit disturbance as part of the comprehensive kidney vacuity strategy.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eTonic restraint and digestive support:\u003c\/strong\u003e Balances the heavy yin, blood, and yang tonics through four classical restraining herbs: Ze Xie (drains dampness and clears the kidney, the classical restraining herb in Rehmannia-based kidney yin formulas), Mu Dan Pi (clears deficiency heat and invigorates blood), Chen Pi (moves qi and regulates the middle jiao), and Sha Ren (awakens the spleen, moves qi, and transforms dampness).

In TCVM, the spleen is the post-natal root of qi and blood production; its transforming and distributing function supports the kidney-targeting tonics.
