Recommended by holistic veterinarians, Herbsmith Rx Liu Wei Di Huang San nourishes Yin and supports a veterinarian-confirmed Kidney and Liver Yin deficiency pattern in dogs, cats, and horses. Its six-ingredient structure combines Shu Di Huang, Shan Zhu Yu, and Shan Yao for traditional nourishment and consolidation with Fu Ling, Mu Dan Pi, and Ze Xie for complementary Dampness-draining and Heat-clearing functions. This traditional approach may be selected when dryness, fatigue, low-back stiffness, restlessness, or urinary changes fit the complete pattern. Available as 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; your authorizing veterinarian will provide specific guidance.

What It Supports
- Traditional Yin nourishment: Shu Di Huang contributes Kidney Yin, Essence, and Blood nourishment within the formula's constitutional framework.
- Consolidation and complementary nourishment: Shan Zhu Yu traditionally nourishes Liver and Kidney and consolidates Essence, while Shan Yao supports Spleen, Lung, and Kidney functions.
- Balanced formula architecture: Fu Ling, Mu Dan Pi, and Ze Xie complement the nourishing ingredients with traditional drainage and Heat clearing. Their inclusion does not guarantee digestive tolerance or eliminate adverse effects.
- Pattern-specific urinary support: The existing listing includes urinary frequency within a Yin-deficiency presentation. Changes in thirst or urination require veterinary assessment; this formula is not a substitute for diagnosis or treatment of urinary obstruction, infection, or kidney disease.
TCVM Principles
- Primary action: Nourish Kidney and Liver Yin, support Essence, and balance nourishment with Dampness drainage and Heat clearing.
- Classical framework: The six-ingredient Liu Wei Di Huang structure is traditionally described as three nourishing ingredients and three balancing or draining ingredients. These are functional groupings, not equal proportions or a guarantee of long-term safety.
- Pattern differentiation: Kidney and Liver are traditional functional terms here, not proof of disease in those anatomical organs. Tongue, pulse, thermal signs, hydration, digestion, and the underlying clinical diagnosis guide selection together.
- Digestive caution: Significant poor appetite, loose stools, or Dampness with Spleen Qi deficiency may limit tolerance of the nourishing formula. Your veterinarian should reassess suitability rather than assuming the balancing ingredients prevent digestive upset.
- Clinical warning: Straining with little or no urine, repeated unsuccessful litter-box visits, or inability to urinate requires immediate veterinary care. New excessive thirst, urinary changes, weight loss, or marked weakness also needs evaluation. Sudden inability to stand, major trauma, or rapidly worsening hindlimb weakness should not be treated as a Yin pattern alone.
- Additional review: Discuss pregnancy or nursing, chronic illness, dehydration, and all medicines before starting. Do not restrict water to manage urinary frequency.

Confirm the dog dose at the overlapping 80 lb boundary. Numeric doses and the horse schedule are preserved from the existing listing, not independently manufacturer-verified. Continue only for the prescribed duration, or as directed by your veterinarian; the subsequent schedule does not establish indefinite maintenance safety. Veterinary authorization is required. Stop administration and contact your veterinarian for suspected adverse reactions, persistent digestive upset, or worsening signs.

Source and preparation details: The six ingredient designations are retained from the current listing. Confirm complete botanical species, proportions, processing, and blend-specific composition against the manufacturer label. Shu Di Huang's unusual supplied Latin wording requires confirmation; the actual preparation, including any wine processing, is not documented here. Shan Yao's supplied Radix designation should be checked against the manufacturer's plant-part documentation rather than silently changed. Full species-level identities are not established for every ingredient by these pharmacognostic names. Prior comparisons with Six Ingredient with Rehmannia, Rehmannia 6, Six Flavor Rehmannia Pills, Six Flavor Tea, and Quiet Contemplative do not establish identical ingredients, concentrations, or dosing.

Active Ingredient TCVM Actions
The six ingredients combine a nourishing and consolidating layer with a complementary Dampness-draining and Heat-clearing layer. The traditional paired interpretation explains the formulation strategy without proving that any ingredient necessarily causes, or another always prevents, a particular adverse effect.
- Shu Di Huang (Radix Rehmanniae Glutinosae Conquitae, as listed) - Prepared Rehmannia Root: Traditionally nourishes Kidney Yin, Essence, and Blood and fills the Marrow. It anchors the nourishing layer; exact preparation and proportions need label confirmation.
- Shan Zhu Yu (Fructus Corni Officinalis) - Cornus Fruit: Traditionally nourishes Liver and Kidney and consolidates Essence. Its astringing role is part of the TCVM framework, not proof that urinary frequency is caused by Essence leakage.
- Shan Yao (Radix Dioscoreae Oppositae, as listed) - Chinese Yam: Traditionally supports Spleen and Lung Qi and Yin and stabilizes Kidney functions. It complements the nourishing layer without guaranteeing absorption or preventing digestive stagnation.
- Fu Ling (Sclerotium Poriae Cocos) - Poria Sclerotium: Traditionally supports Spleen function, drains Dampness, and calms the Spirit. Here it contributes the balancing drainage layer; its individual actions do not establish a separate calming indication.
- Mu Dan Pi (Cortex Moutan Radicis) - Tree Peony Root Bark: Traditionally clears Heat, cools Blood, and moves Blood, contributing cooling and movement alongside the nourishing ingredients.
- Ze Xie (Rhizoma Alismatis Orientalis) - Alisma Rhizome: Traditionally drains Dampness, promotes urination, and clears lower-burner Heat. Its role does not establish a measured diuretic effect or justify use during urinary obstruction.
Potential Drug Interactions
Herbsmith Rx Liu Wei Di Huang San contains nourishing Rehmannia and Cornus, Blood-moving Mu Dan Pi, and Dampness-draining Ze Xie and Fu Ling. Pets taking prescription medications should use the formula under veterinary supervision because herb-drug interaction research in dogs and cats is limited. Horses receiving prescriptions also require review. Traditional Yin nourishment, Blood movement, and drainage do not establish a quantified hormonal, anticoagulant, or diuretic effect for this finished preparation.
Medication categories warranting extra caution include anticoagulant and antiplatelet medicines, diuretics, immunosuppressants, hormonal medicines, and multiple concurrent prescriptions. Discuss hydration, kidney function, and any planned procedures with your veterinarian. Stop administration and seek advice for suspected adverse reactions, unusual bleeding, persistent digestive upset, or worsening urinary signs; inability to urinate requires immediate care. Your veterinarian can determine appropriateness based on your animal's condition, medications, and laboratory results.

Frequently Asked Questions
What is Liu Wei Di Huang San used for in TCVM?
It nourishes Kidney and Liver Yin in a veterinarian-confirmed pattern that may include dryness, fatigue, low-back stiffness, restlessness, and urinary changes. The six-ingredient combination balances nourishment with traditional drainage and Heat clearing. These pattern terms do not diagnose anatomical kidney or liver disease, and urinary changes, weakness, or dryness require assessment of their medical cause.
How is Liu Wei Di Huang San administered to dogs, cats, and horses?
Dogs and cats use the Canine Blend mixed into food. Dogs under 30 lbs receive ½ tsp twice daily, or as directed by your veterinarian. Dogs 30-80 lbs receive 1 tsp twice daily, or as directed by your veterinarian. Dogs 80-120 lbs receive 1½ tsp twice daily, or as directed by your veterinarian. Dogs over 120 lbs receive 2 tsp twice daily, or as directed by your veterinarian. Cats receive ¼ tsp twice daily, or as directed by your veterinarian. Confirm the dose at the overlapping 80 lb dog boundary.
For a 1,000 lb horse using the Equine/Horse Blend, give two tablespoons twice daily in grain, or as directed by your veterinarian. Continue the initial schedule for 20 days, or as directed by your veterinarian. Then give two tablespoons once daily in grain, or as directed by your veterinarian. If initially refused, introduce a small amount in grain and gradually increase until accustomed to the taste, or as directed by your veterinarian. Continue only for the prescribed duration, or as directed by your veterinarian.
How are progress, tolerance, and duration assessed?
Your veterinarian reviews hydration, thirst and urination, appetite, stool, comfort, energy, body condition, tongue and pulse findings, and laboratory results when appropriate. Fixed 4-to-8-week or 3-to-6-month improvement timelines and blanket long-term safety are not established. Continue only for the prescribed duration, or as directed by your veterinarian. Poor appetite, persistent loose stools, or worsening signs calls for reassessment. Straining with little or no urine or inability to urinate needs immediate veterinary care, not a longer trial.
Why are three balancing ingredients included with the three nourishing ingredients?
Shu Di Huang, Shan Zhu Yu, and Shan Yao provide the nourishing and consolidating layer. Ze Xie, Mu Dan Pi, and Fu Ling complement it with traditional drainage and Heat-clearing functions. This is commonly described as the three-tonics-and-three-drains architecture. It is a formulation principle rather than proof that every nourishing ingredient causes Dampness or Heat, or that the balancing ingredients make prolonged use universally safe. Individual digestion, hydration, pattern, medications, and clinical findings still determine suitability.
