Herbsmith Rx Xiao Yao San for Cats, Dogs and Horses

Veterinary Authorization Required for TCVM Herbal Formulas - TCVM Pet Supply

Herbsmith Rx Xiao Yao San is a classical Chinese herbal formula recommended by holistic veterinarians to support liver qi flow, spleen function, and blood nourishment in dogs, cats, and horses. Based on the traditional formula Xiao Yao San (also known as Tang Kuei and Bupleurum Combination, Rambling Powder, Free and Easy Wanderer, Liver Happy, Relaxed Wanderer, Bupleurum and Tang Kuei, and Rambling Ease Powder), it spreads the liver qi, strengthens the spleen, and nourishes the blood. One of the most widely used formulas in Traditional Chinese Medicine, it is well suited for pets presenting with liver qi stagnation causing digestive irregularity, bloating, irritability, restlessness, or anxiety, particularly where blood deficiency underlies or accompanies the stagnation. 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.

What It Supports

  • Liver qi spreading: Relieves liver qi constraint and stagnation, addressing the restlessness, irritability, and emotional tension that arise when the liver loses its ability to maintain the smooth flow of qi throughout the body.
  • Spleen strengthening: Tonifies the spleen and supports healthy digestion, addressing the bloating, loose stools, and digestive irregularity that develop when liver qi stagnation invades the spleen and impairs its transforming and transporting functions.
  • Blood nourishment: Nourishes the liver blood and yin that are often depleted in liver qi stagnation patterns, addressing the root blood deficiency that makes the liver susceptible to constraint and stagnation.
  • Emotional and behavioral balance: Supports a calm and settled disposition in pets presenting with anxiety, restlessness, or mood-related behavioral changes arising from liver qi stagnation and blood deficiency.

TCVM Principles

  • Primary action: Spreads constrained liver qi and nourishes liver blood simultaneously, addressing both the branch (qi stagnation) and the root (blood deficiency) of the pattern in a single, elegantly balanced formula.
  • Secondary action: Strengthens the spleen to restore healthy digestion and prevent the liver from over-controlling the earth element, ensuring the middle burner can produce sufficient qi and blood to support recovery.

Available Forms

  • Powder - Canine Blend (for dogs and cats): Available in 75 g, 150 g, 500 g, 900 g, and 1200 g sizes; mix into food at the recommended dose for your pet's weight. Cats and dogs both use this blend.
  • Powder - Equine/Horse Blend (for horses only): Available in 150 g, 500 g, 900 g, and 1200 g sizes; mix into grain at the recommended dose for your horse.

Suggested Use

For Dogs (Canine Blend Powder):

  • Under 30 lbs: ½ tsp twice daily, or as prescribed
  • 30-80 lbs: 1 tsp twice daily, or as prescribed
  • 80-120 lbs: 1½ tsp twice daily, or as prescribed
  • Over 120 lbs: 2 tsp twice daily, or as prescribed

For Cats (Canine Blend Powder): ¼ tsp twice daily, or as prescribed

For Horses (Equine/Horse Blend, 1,000 lb horse): Two tablespoons twice daily for 20 days, then two tablespoons once daily in grain. If the horse initially refuses, start with a small amount mixed into grain and gradually increase until the horse is accustomed to the taste. Most horses will readily accept the herbs in their grain.

Active Ingredient TCVM Actions

Xiao Yao San is a six-herb formula that balances liver, spleen, and blood in one of the most elegant and widely used combinations in Traditional Chinese Medicine, addressing both the root and branch of liver qi stagnation with blood deficiency:

  • Chai Hu (Radix Bupleuri) - Bupleurum Root: The principal herb; spreads liver qi, relieves constraint, and raises the clear yang; directly addresses the liver qi stagnation that is the primary pattern of this formula, helping restore the liver's ability to maintain smooth qi flow throughout the body.
  • Dang Gui (Radix Angelicae Sinensis) - Dong Quai Root: Tonifies and invigorates the blood, moistens the intestines, and supports the liver blood; nourishes the blood deficiency that underlies liver qi stagnation, addressing the root cause of the pattern while also gently moving stagnant blood.
  • Bai Shao (Radix Paeoniae Lactiflorae) - White Peony Root: Nourishes the blood, softens the liver, and calms liver yang; works with Dang Gui to replenish liver blood and yin, and moderates the liver's tendency to over-control by softening its constraint and reducing tension.
  • Bai Zhu (Rhizoma Atractylodis Macrocephalae) - White Atractylodes Rhizome: Strengthens the spleen, dries dampness, and supports digestion; addresses the spleen deficiency that results from liver over-control, restoring the middle burner's ability to transform and transport food and generate qi and blood.
  • Fu Ling (Sclerotium Poriae Cocos) - Poria Mushroom: Strengthens the spleen, resolves dampness, and calms the spirit; works with Bai Zhu to restore spleen function and addresses the restlessness and anxiety associated with liver qi stagnation affecting the heart spirit.
  • Zhi Gan Cao (Honey-fried Radix Glycyrrhizae Uralensis) - Honey-fried Licorice Root: Tonifies the spleen qi, moderates the actions of the other herbs, and harmonizes the formula; the honey-frying enhances its spleen-tonifying properties compared to raw licorice, ensuring the formula is well tolerated and gently supports the middle burner.

Potential Drug Interactions

Xiao Yao San contains liver-regulating and blood-nourishing herbs including Chai Hu and Dang Gui, which have mild hormone-influencing and hepatic-metabolizing properties. Pets currently on prescription medications should use this formula under veterinary supervision, as herb-drug interaction research in dogs and cats remains limited.

Medication categories warranting extra caution include hepatic medications or drugs with significant liver metabolism, hormonal therapies, immunosuppressive drugs, and pets managing multiple concurrent prescriptions. Your authorizing veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

Frequently Asked Questions

What conditions is Xiao Yao San used for in TCVM?

In Traditional Chinese Veterinary Medicine, Xiao Yao San is indicated for liver qi stagnation with underlying blood deficiency, presenting as digestive irregularity, bloating, irritability, restlessness, anxiety, and a wiry or thin pulse. It is one of the most widely used formulas in TCVM and is a good alternative to Tang Kuei and Bupleurum Combination, Rambling Powder, Free and Easy Wanderer, Liver Happy, Relaxed Wanderer, Bupleurum and Tang Kuei, and Rambling Ease Powder. It is appropriate for pets whose behavioral or digestive signs have a liver qi and blood deficiency component.

How is Xiao Yao San administered to dogs, cats, and horses?

Mix the powder directly into food or grain at the dose recommended for your pet's species and body weight. Both dogs and cats use the Canine Blend; horses use the Equine/Horse Blend. Dogs and cats receive the formula twice daily; horses receive two tablespoons twice daily for the first 20 days, then once daily for maintenance. Your authorizing veterinarian will confirm the appropriate dose and schedule for your individual pet.

How long does it take to see results with Xiao Yao San?

Response time varies depending on the severity and chronicity of the liver qi stagnation and blood deficiency pattern. Many pets show improvement in digestive regularity, bloating, restlessness, and behavioral balance within 3 to 6 weeks of consistent use. Chronic or deeply rooted patterns may require a longer course of treatment, and your veterinarian may recommend periodic reassessment to adjust the formula or dosing as your pet responds.

Can Xiao Yao San be combined with other TCVM formulas or conventional medications?

Combination with complementary TCVM formulas is common in holistic veterinary practice and should be guided by your authorizing veterinarian based on your pet's full pattern diagnosis. Because this formula contains Chai Hu, which is processed by the liver and may influence hormonal regulation, veterinary oversight is especially important if your pet is on hepatic medications, hormonal therapies, or immunosuppressive drugs, to ensure the treatment plan is appropriate for your pet's overall health status.
