Liver Support Formula is built on Four Substances Decoction (Si Wu Tang) as its Blood-tonifying core, with added Heart-nourishing and muscle-relaxing herbs. The mixing of sweet and sour herbs produces a potent Yin-tonifying and nourishing effect throughout.
Liver Support Formula contains several potent Chinese herbs, including Blood-nourishing, Yin-tonifying, and Blood-invigorating herbs with known hepatic, cardiovascular, and neurological activity. Because herb-drug interaction research in dogs and cats is limited, pets taking prescription medications should use this formula under veterinary supervision. Avoid use in animals with signs of Dampness.
Extra caution may be appropriate for pets receiving hepatic medications, sedatives or anxiolytics, anticoagulant or antiplatelet medications, or multiple prescription medications. Your veterinarian can determine whether Liver Support Formula is appropriate based on your pet's condition, medications, and laboratory results.

In Traditional Chinese Veterinary Medicine, Liver Support Formula (Bu Gan Tang) is traditionally used to nourish Liver Yin and Blood and subdue Liver Yang. It is indicated for patterns of Liver Yin and Blood deficiency with Liver Yang rising, commonly used to support emotional calm, healthy skin, musculoskeletal comfort, and liver enzyme levels - particularly in dogs, who are more prone to Liver Blood deficiency.
Liver Support Formula is available in liquid extract (1 oz, 4 oz, or 8 oz) or 500mg tablets (60, 120, or 300 count). Liquid can be mixed into food or administered directly; tablets can be given directly or hidden in food. Dosing varies by species and body weight - your authorizing veterinarian will provide specific guidance.
Results vary by individual and the severity of the pattern. Blood and Yin deficiency patterns often require consistent use over several weeks to months before significant improvement is seen. Some animals may show improvement in emotional calm and muscle comfort relatively sooner. Your authorizing veterinarian can help set appropriate expectations based on your pet's TCVM diagnosis.
Always consult your veterinarian before combining Liver Support Formula with other medications or supplements. Your authorizing veterinarian will monitor for potential interactions through routine lab work and diagnostic testing. Key interactions to discuss include hepatic medications, sedatives, and anticoagulants. See the Potential Drug Interactions section above for details.
