Also known as Tonify the Liver Powder, Liver Support Formula, and Rehmannia and Peony Combination, Bu Gan San is a seven-herb formula built around the Si Wu Tang (Four Substance Decoction) blood-nourishing core, Dang Gui, Chuan Xiong, Bai Shao, and Shu Di Huang, extended with Suan Zao Ren, Mu Gua, and Zhi Gan Cao to address the liver blood and yin vacuity pattern comprehensively. The formula's primary therapeutic logic centers on the TCVM understanding that the liver stores the blood and is nourished by the blood: when liver blood and yin are insufficient, the liver loses the moistening and nourishing it requires to maintain its free-flowing and harmonizing function, generating a cascade of downstream signs including tendon and sinew malnourishment, spirit and sleep disturbance, visual dimness, dry and brittle nails and hair coat, and the liver-specific pattern of deficient blood failing to anchor the liver yang and producing mild upward disturbance. Bu Gan San's seven herbs address the liver blood and yin vacuity from three simultaneous directions: powerfully nourishing and generating the liver blood and yin from the blood level (Shu Di Huang, Dang Gui, Bai Shao, Suan Zao Ren); moving and regulating the blood to prevent the nourishing herbs from generating stagnation (Chuan Xiong, Dang Gui); and relaxing and moistening the sinews and channels that liver blood vacuity is failing to nourish (Mu Gua, Bai Shao, Zhi Gan Cao). Well suited for dogs, cats, and horses presenting with liver blood and yin vacuity, characterized by chronic fatigue and general debility from blood vacuity failing to nourish and energize the body; tendon, sinew, and musculoskeletal stiffness or cramping from liver blood vacuity failing to moisten and relax the sinews; a dull, poor, or dry hair coat and brittle nails from blood vacuity failing to nourish the liver's external manifestations; restlessness, disturbed sleep, or anxious behavior from blood vacuity failing to anchor and calm the liver spirit; visual dimness or reduced visual acuity from liver blood vacuity failing to nourish the eyes, which the liver opens into; a pale or pale-lavender tongue with a thin coating and a fine, wiry, or choppy pulse reflecting the blood vacuity (pale, fine) and the liver's compromised free-flowing function (wiry, choppy). Available as a concentrated powder mixed into food; dogs and cats 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\u003eLiver blood and yin nourishment through Shu Di Huang as the principal blood and yin tonic:\u003c\/strong\u003e Powerfully nourishes the liver and kidney yin and blood, replenishes the essence (jing), and provides the constitutional yin and blood foundation from which the formula's entire nourishing strategy draws its deepest replenishment through Shu Di Huang (prepared rehmannia root, Radix Rehmanniae Glutinosae Conquitae), the chief yin and blood tonic of Bu Gan San. Shu Di Huang's sweet, slightly warm, and heavy nature enters the liver, kidney, and heart channels at the deepest constitutional level, nourishing the blood and yin from the essence level and providing the substantial replenishment that the formula's lighter blood-nourishing herbs build upon.

Dang Gui's sweet, acrid, and warm nature enters the liver, heart, and spleen channels to nourish liver blood while activating and moving it, ensuring the formula's powerful nourishing herbs are accompanied by the movement needed to prevent the restored blood from becoming stagnant. Dang Gui has mild anticoagulant effects from its coumarin content; when combined with Chuan Xiong, this compounded anticoagulant interaction requires veterinary coordination in animals on anticoagulant medications.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eLiver yin nourishment, liver yang anchoring, and sinew relaxation through Bai Shao:\u003c\/strong\u003e Nourishes the liver yin and blood, anchors the liver yang, softens the liver, relieves cramping and spasm, and clears vacuity heat through Bai Shao (white peony root, Radix Paeoniae Lactiflorae). Bai Shao's sour, bitter, and slightly cold nature enters the liver and spleen channels to nourish the liver yin, anchor the yang, and soften and relax the sinews and tendons that liver blood vacuity is failing to moisten. In TCVM, the liver governs the sinews: when liver blood is sufficient, the sinews are supple and freely movable; when liver blood is vacuous, the sinews become stiff, cramped, and prone to spasm. Bai Shao works with Mu Gua and Zhi Gan Cao to form the formula's sinew-relaxing triad. Bai Shao has mild antiplatelet effects from its paeoniflorin content; monitoring is warranted in animals on anticoagulant medications.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eBlood activation and qi movement through Chuan Xiong preventing stagnation from the heavily nourishing herbs:\u003c\/strong\u003e Activates the blood, moves the qi, dispels wind, and prevents blood stagnation through Chuan Xiong (ligusticum root, Radix Ligustici Chuanxiong), the formula's primary blood-activating and qi-moving herb. Chuan Xiong's acrid, warm nature enters the liver, gallbladder, and pericardium channels to move qi and blood simultaneously, transforming the nourished, replenished blood from a static pool into a freely circulating vital substance. Combined with Dang Gui and Bai Shao, the formula's three blood-activating herbs create a compounded anticoagulant and antiplatelet interaction concern in animals on anticoagulant medications requiring veterinary coordination.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eHeart blood nourishment and spirit calming through Suan Zao Ren addressing the restlessness and disturbed sleep of liver-heart blood vacuity:\u003c\/strong\u003e Nourishes the heart blood and liver blood, calms the spirit, generates fluids, and addresses restlessness, disturbed sleep, and anxious behavior through Suan Zao Ren (sour jujube seed, Semen Zizyphi Spinosae). The liver stores the blood at rest and releases it to the heart for circulation; when liver blood is vacuous, the heart receives insufficient blood to nourish the spirit, generating the restlessness and disturbed sleep of the liver-heart blood vacuity pattern. Suan Zao Ren's sedative and anxiolytic properties from its jujuboside and spinosin content warrant monitoring in animals on sedative, anxiolytic, or central nervous system-modulating medications.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eSinew relaxation and dampness transformation through Mu Gua targeting the musculoskeletal stiffness of liver blood vacuity:\u003c\/strong\u003e Relaxes the sinews and tendons, transforms dampness, harmonizes the stomach, and relieves cramping and stiffness through Mu Gua (Chinese quince fruit, Fructus Chaenomelis Lagenariae).

The honey-fried preparation enhances its spleen qi-tonifying and middle jiao-moistening action, providing digestive protection and harmonization in a formula whose heavy nourishing herbs could generate middle jiao stagnation without this moderating presence.

The formula's therapeutic logic reflects the TCVM understanding that the liver stores the blood and is nourished by the blood: when liver blood is sufficient the liver performs all its governing functions (storing blood, ensuring free flow, governing the sinews, opening into the eyes, manifesting in the nails, housing the hun spirit); when liver blood is vacuous each of these functions is progressively compromised.

Clinical differentiation centers on characteristic nourishment-failure signs (pale tongue, fine pulse, dry hair coat, tendon stiffness, visual dimness, disturbed sleep) without the excess-heat tongue coating, full pulse, or strong qi-stagnation signs of excess liver patterns.

More substantial restoration, reflected in improved hair coat quality, progressive reduction in tendon and sinew stiffness, and normalization of the tongue color from pale toward pink, typically requires 4 to 8 weeks or longer.

Si Wu Tang alone addresses blood vacuity at the blood level; Bu Gan San extends this core with three additional herbs that target the specific downstream consequences of liver blood vacuity that Si Wu Tang alone does not fully address. Suan Zao Ren addresses the heart-liver blood vacuity pattern with spirit disturbance: when liver blood is insufficient, the heart shen loses nourishment and becomes restless, and Suan Zao Ren nourishes both the heart and liver blood channels simultaneously to calm the spirit at its blood-nourishment root. Mu Gua specifically relaxes and moistens the sinews and tendons that liver blood vacuity is failing to nourish, targeting the musculoskeletal stiffness that is one of the most clinically prominent signs in animals. Together, Bu Gan San provides a more complete clinical response to the liver blood and yin vacuity pattern by addressing the spirit, sinew, and musculoskeletal dimensions alongside the foundational blood nourishment.\u003c\/span\u003e\u003c\/p\u003e","published_at":"2022-05-20T18:00:13-05:00","created_at":"2022-04-28T12:52:20-05:00","vendor":"Herbsmith Rx","type":"Pet Vitamins \u0026 Supplements","tags":["Herb_Type_Powder","Product_Type_Herb","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":40018715705414,"title":"Powder -

Also known as Tonify the Liver Powder, Liver Support Formula, and Rehmannia and Peony Combination, Bu Gan San is a seven-herb formula built around the Si Wu Tang (Four Substance Decoction) blood-nourishing core, Dang Gui, Chuan Xiong, Bai Shao, and Shu Di Huang, extended with Suan Zao Ren, Mu Gua, and Zhi Gan Cao to address the liver blood and yin vacuity pattern comprehensively. The formula's primary therapeutic logic centers on the TCVM understanding that the liver stores the blood and is nourished by the blood: when liver blood and yin are insufficient, the liver loses the moistening and nourishing it requires to maintain its free-flowing and harmonizing function, generating a cascade of downstream signs including tendon and sinew malnourishment, spirit and sleep disturbance, visual dimness, dry and brittle nails and hair coat, and the liver-specific pattern of deficient blood failing to anchor the liver yang and producing mild upward disturbance. Bu Gan San's seven herbs address the liver blood and yin vacuity from three simultaneous directions: powerfully nourishing and generating the liver blood and yin from the blood level (Shu Di Huang, Dang Gui, Bai Shao, Suan Zao Ren); moving and regulating the blood to prevent the nourishing herbs from generating stagnation (Chuan Xiong, Dang Gui); and relaxing and moistening the sinews and channels that liver blood vacuity is failing to nourish (Mu Gua, Bai Shao, Zhi Gan Cao). Well suited for dogs, cats, and horses presenting with liver blood and yin vacuity, characterized by chronic fatigue and general debility from blood vacuity failing to nourish and energize the body; tendon, sinew, and musculoskeletal stiffness or cramping from liver blood vacuity failing to moisten and relax the sinews; a dull, poor, or dry hair coat and brittle nails from blood vacuity failing to nourish the liver's external manifestations; restlessness, disturbed sleep, or anxious behavior from blood vacuity failing to anchor and calm the liver spirit; visual dimness or reduced visual acuity from liver blood vacuity failing to nourish the eyes, which the liver opens into; a pale or pale-lavender tongue with a thin coating and a fine, wiry, or choppy pulse reflecting the blood vacuity (pale, fine) and the liver's compromised free-flowing function (wiry, choppy). Available as a concentrated powder mixed into food; dogs and cats 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\u003eLiver blood and yin nourishment through Shu Di Huang as the principal blood and yin tonic:\u003c\/strong\u003e Powerfully nourishes the liver and kidney yin and blood, replenishes the essence (jing), and provides the constitutional yin and blood foundation from which the formula's entire nourishing strategy draws its deepest replenishment through Shu Di Huang (prepared rehmannia root, Radix Rehmanniae Glutinosae Conquitae), the chief yin and blood tonic of Bu Gan San.

The formula's yin-nourishing and blood-nourishing strategy is not appropriate for animals with significant dampness, phlegm, or spleen yang vacuity cold.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eHow long does it take to see results with Bu Gan San?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eAs a formula addressing a chronic constitutional blood and yin vacuity pattern, Bu Gan San requires a sustained treatment course to meaningfully restore the liver blood and yin. Early improvement in the most responsive signs (reduced restlessness, improved sleep quality, mild improvement in energy) may be seen within 2 to 4 weeks. More substantial restoration, reflected in improved hair coat quality, progressive reduction in tendon and sinew stiffness, and normalization of the tongue color from pale toward pink, typically requires 4 to 8 weeks or longer. Deeply established liver blood and yin vacuity may require 3 to 6 months of sustained treatment, or as directed by your veterinarian. Your authorizing veterinarian will monitor tongue, pulse, and clinical signs throughout the treatment course.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eHow does Bu Gan San relate to Si Wu Tang, and why does it include Suan Zao Ren and Mu Gua in addition to the Four Substance Decoction core?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eBu Gan San is built on the Si Wu Tang (Four Substance Decoction) core, Shu Di Huang, Dang Gui, Bai Shao, and Chuan Xiong, the most foundational blood-nourishing formula in classical TCVM. Si Wu Tang alone addresses blood vacuity at the blood level; Bu Gan San extends this core with three additional herbs that target the specific downstream consequences of liver blood vacuity that Si Wu Tang alone does not fully address. Suan Zao Ren addresses the heart-liver blood vacuity pattern with spirit disturbance: when liver blood is insufficient, the heart shen loses nourishment and becomes restless, and Suan Zao Ren nourishes both the heart and liver blood channels simultaneously to calm the spirit at its blood-nourishment root. Mu Gua specifically relaxes and moistens the sinews and tendons that liver blood vacuity is failing to nourish, targeting the musculoskeletal stiffness that is one of the most clinically prominent signs in animals. Together, Bu Gan San provides a more complete clinical response to the liver blood and yin vacuity pattern by addressing the spirit, sinew, and musculoskeletal dimensions alongside the foundational blood nourishment.\u003c\/span\u003e\u003c\/p\u003e"}
