Herbsmith Rx Long Dan Xie Gan San for Cats, Dogs and Horses

Veterinary Authorization Required for TCVM Herbal Formulas - TCVM Pet Supply

Herbsmith Rx Long Dan Xie Gan San is a classical Chinese herbal formula recommended by holistic veterinarians to drain excess fire from the liver and gallbladder, clear and drain damp-heat from the lower burner, and address liver and gallbladder repletion heat and damp-heat patterns in dogs, cats, and horses. Comparable to Gentiana Longdancao Decoction to Drain the Liver, Snake and Dragon, Quell Fire, Gentiana Drain the Liver Pills, Gentiana Drain Fire, and Gentiana Combination, it drains excess fire from the liver and gallbladder, clears and drains damp-heat from the lower burner, and addresses both liver and gallbladder repletion heat and liver and gallbladder damp-heat. One of the most powerful fire-draining and damp-heat-clearing formulas in the classical Chinese herbal repertoire, Long Dan Xie Gan San addresses two distinct but related presentations of liver-gallbladder excess: upward-flaring liver and gallbladder fire producing the heat signs in the head, eyes, ears, and upper body, and downward-pouring damp-heat producing the damp-heat signs in the lower burner, urogenital tract, and lower limbs. The formula uses three coordinated herb groups: a fire-draining group (Long Dan Cao, Huang Qin, Zhi Zi) that clears the liver-gallbladder fire at the pattern's root; a damp-heat-draining group (Mu Tong, Che Qian Zi, Ze Xie) that drains the damp-heat downward and out through urination; and an essential yin-and-blood-protecting group (Sheng Di Huang, Dang Gui) that prevents the formula's intensely draining action from injuring the liver yin and blood during the treatment course. Well suited for dogs, cats, and horses presenting with liver and gallbladder fire or damp-heat, characterized by irritability or agitation, redness or heat in the eyes or ears, headshaking, bitter taste or yellow coatings in the mouth, urogenital damp-heat signs including burning or frequent urination or abnormal discharge, a red tongue with a yellow or yellow greasy coating, and a wiry rapid or slippery rapid pulse reflecting the liver-gallbladder fire or damp-heat pattern. 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 and gallbladder fire draining: Drains excess fire from the liver and gallbladder using Long Dan Cao as the principal fire-draining herb and the combined heat-clearing action of Huang Qin and Zhi Zi, addressing the upward-flaring liver-gallbladder fire that produces the irritability, agitation, redness or heat in the eyes and ears, headshaking, bitter taste, and the other fire-heat signs in the head and upper body characteristic of the liver-gallbladder repletion fire pattern in dogs, cats, and horses.
  • Lower burner damp-heat clearing and drainage: Clears and drains damp-heat from the lower burner using Mu Tong, Che Qian Zi, and Ze Xie's coordinated damp-heat-draining and urination-promoting action, guiding the liver-gallbladder damp-heat downward and out of the body through the urine, addressing the lower burner damp-heat signs of burning or frequent urination, urogenital inflammation or abnormal discharge, and the damp-heat accumulation in the lower jiao that arises when liver-gallbladder fire combines with dampness and pours downward into the lower burner.
  • Liver yin and blood protection during draining treatment: Protects the liver yin and blood from the formula's intensely draining action using Sheng Di Huang's yin-nourishing and blood-cooling action and Dang Gui's blood-nourishing and blood-invigorating action, preventing the aggressive fire-draining and damp-heat-clearing herbs from injuring the liver yin and blood during the sustained treatment course, ensuring the formula drains the excess without creating a deficiency pattern from over-draining in animals with any underlying liver yin vulnerability.
  • Liver channel guidance and clear qi raising: Guides the formula's fire-draining action specifically into the liver and gallbladder channels and raises the clear qi using Chai Hu's liver-channel-guiding and qi-raising action, ensuring the formula's coordinated fire-draining and damp-heat-clearing strategy is effectively directed to the liver and gallbladder channels where the excess fire and damp-heat are lodged, and raising the clear qi that the liver-gallbladder fire has disrupted alongside the fire-draining treatment.

TCVM Principles

  • Primary action - liver and gallbladder fire draining with lower burner damp-heat clearance through three coordinated herb groups: Addresses liver-gallbladder repletion fire and damp-heat through three coordinated herb groups that simultaneously drain the fire at the root, guide the damp-heat out of the body, and protect the yin and blood from the draining treatment: (1) Fire-draining group: Long Dan Cao (bitter cold, directly drains liver-gallbladder fire and damp-heat as the principal herb), Huang Qin (clears heat and dries dampness in the upper and middle jiao), and Zhi Zi (clears heat from all three burners and guides heat out through the urine); (2) Damp-heat-draining group: Mu Tong (drains heat through the small intestine and promotes urination), Che Qian Zi (clears heat and promotes urination to drain the lower burner damp-heat), and Ze Xie (drains dampness and kidney fire through the urine); and (3) Chai Hu (guides the formula to the liver and gallbladder channels and raises the clear qi). The three groups work simultaneously so the liver-gallbladder fire is drained at the root, the damp-heat is guided out through urination, and the formula's liver-channel specificity is maintained throughout the treatment course.
  • Secondary action - essential yin and blood protection to prevent draining injury with harmonization: Protects the liver yin and blood from the formula's intensely draining and bitter-cold composition using Sheng Di Huang (raw rehmannia, which nourishes the yin and cools the blood without the prepared form's heavy stickiness, appropriate for the excess-heat context of this formula) and Dang Gui (which nourishes the liver blood and provides mild blood-invigorating action to prevent blood stasis from the formula's cooling effect on the blood), ensuring the formula drains the excess liver-gallbladder fire and damp-heat without creating yin or blood deficiency as a treatment side effect. Gan Cao harmonizes the formula's multiple bitter-cold and draining herbs and protects the spleen from the formula's intensely cold and draining character during the acute treatment course.

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.

Active Ingredient TCVM Actions

Long Dan Xie Gan San is a ten-herb formula addressing liver and gallbladder repletion fire and damp-heat through three coordinated herb groups: a fire-draining and heat-clearing group that addresses the excess at the root, a damp-heat-draining and urination-promoting group that guides the damp-heat out of the body, and a yin-and-blood-protecting group that prevents the formula's aggressive draining action from injuring the liver yin and blood during the treatment course:

  • Long Dan Cao (Radix Gentianae Longdancao) - Chinese Gentian Root (14.5%): Principal herb; drains fire from the liver and gallbladder, clears damp-heat from the liver and gallbladder channels, and drains damp-heat from the lower burner; the most powerful bitter-cold liver-fire-draining and damp-heat-clearing herb in the Chinese materia medica, directly draining the excess fire from the liver and gallbladder channels and simultaneously clearing the damp-heat from the lower burner as the formula's defining principal herb, providing the foundational fire-draining and damp-heat-clearing action from which the formula takes its name.
  • Huang Qin (Radix Scutellariae) - Scutellaria Root / Skullcap Root (7%): Clears heat and dries dampness in the upper and middle jiao, drains fire, and cools the blood; the upper-jiao and middle-jiao heat-clearing herb of the fire-draining group, providing bitter-cold heat-clearing and dampness-drying action in the upper and middle jiao alongside Long Dan Cao's primary liver-gallbladder fire-draining action, and cooling the blood to address the blood-heat component of the liver-fire pattern where the liver fire has entered the blood level.
  • Zhi Zi (Fructus Gardeniae Jasminoidis) - Gardenia Fruit (7%): Clears heat from all three burners, cools the blood, and guides heat out through the urine; the three-burner heat-clearing herb that extends the formula's fire-draining action across all three burners and provides an additional urinary pathway for the liver-gallbladder fire to exit the body, working with Mu Tong, Che Qian Zi, and Ze Xie to guide the cleared heat and damp-heat out of the body through the urine.
  • Mu Tong (Caulis Mutong) - Akebia Stem / Mutong (7%): Drains heat through the small intestine and heart, promotes urination, and unblocks the urinary passages; the primary small-intestine-heat-draining and urination-promoting herb of the damp-heat-draining group, guiding the liver-gallbladder damp-heat through the small intestine and out through the urinary pathway, particularly effective for the lower burner damp-heat signs of burning urination and urogenital inflammation. Used under veterinary supervision and authorization as part of the formula's balanced ten-herb composition, which ensures appropriate clinical oversight of the treatment course.
  • Che Qian Zi (Semen Plantaginis) - Plantain Seed / Plantago Seed (7%): Clears heat, promotes urination, and stops diarrhea; the second urination-promoting herb of the damp-heat-draining group, clearing heat and draining the lower burner damp-heat through the urine alongside Mu Tong and Ze Xie, and providing additional clearing of the heat and dampness from the bladder and urinary tract that are the primary lower burner targets of the formula's damp-heat-draining strategy.
  • Ze Xie (Rhizoma Alismatis Orientalis) - Water Plantain Rhizome / Alisma (14.5%): Drains dampness, promotes urination, and clears kidney fire; the third and highest-proportion herb of the damp-heat-draining group, providing strong dampness-draining and urination-promoting action that drains the damp-heat from the lower burner and kidney through the urine, working with Mu Tong and Che Qian Zi to provide comprehensive lower burner damp-heat drainage and ensuring the dampness component of the liver-gallbladder damp-heat pattern is thoroughly cleared from the lower jiao.
  • Chai Hu (Radix Bupleuri) - Bupleurum Root (14.5%): Spreads the liver qi, guides the formula to the liver and gallbladder channels, raises the clear yang, and relieves constraint; the liver-channel-guiding herb that directs the formula's fire-draining and damp-heat-clearing action specifically into the liver and gallbladder channels where the excess fire and damp-heat are lodged, and raises the clear yang qi that the liver fire has disrupted, ensuring the formula's comprehensive draining strategy is effectively targeted to the correct channels while simultaneously addressing the liver qi constraint that typically coexists with or precedes the liver fire pattern.
  • Sheng Di Huang (Radix Rehmanniae Glutinosae) - Raw Rehmannia Root (14.5%): Nourishes the yin, cools the blood, and clears heat; the primary yin-protecting herb that prevents the formula's intensely bitter-cold and draining composition from injuring the liver yin during the treatment course, using the raw (sheng) form specifically because its yin-nourishing and blood-cooling action is appropriate for the excess-heat context (where the prepared form's heavy stickiness would be contraindicated), protecting the liver yin that the sustained liver-fire pattern has been consuming while the formula's fire-draining herbs address the excess fire at the root.
  • Dang Gui (Radix Angelicae Sinensis) - Dong Quai Root (7%): Nourishes and invigorates the blood and nourishes the liver; the blood-protecting herb that nourishes the liver blood alongside Sheng Di Huang's yin protection and provides mild blood-invigorating action to prevent the formula's intensely cold and draining herbs from causing blood stasis by over-cooling the blood during the sustained treatment course, ensuring the liver blood remains adequately nourished and freely circulating as the liver-gallbladder fire and damp-heat are progressively cleared.
  • Gan Cao (Radix Glycyrrhizae Uralensis) - Licorice Root (7%): Tonifies the spleen qi, clears heat and toxin, and harmonizes the formula; the harmonizing herb that moderates the interaction between the formula's multiple intensely bitter-cold and draining herbs, protecting the spleen and middle jiao from the formula's collectively cold and draining character during the acute treatment course, and coordinating the three herb groups' combined fire-draining, damp-heat-clearing, and yin-blood-protecting actions into a cohesive and well-tolerated formula.

Potential Drug Interactions

Long Dan Xie Gan San is an intensely bitter-cold and draining formula indicated for excess fire and damp-heat patterns, and is not appropriate for deficiency patterns, cold patterns, or animals without clear liver-gallbladder fire or damp-heat signs; extended use in the absence of an active excess pattern may injure the spleen qi and middle jiao through the formula's sustained cold-draining action. Dang Gui has mild anticoagulant and blood-invigorating properties that warrant monitoring in animals on anticoagulant or antiplatelet medications. Mu Tong (Caulis Mutong), as listed in the manufacturer's ingredient specification, warrants awareness regarding the aristolochic acid concerns historically associated with certain Mu Tong species; the formula is used under veterinary authorization and supervision, which allows the authorizing veterinarian to review the specific ingredient sourcing and determine appropriateness for the individual animal, particularly in animals with any pre-existing renal concerns. The formula's multiple urination-promoting herbs (Mu Tong, Che Qian Zi, Ze Xie) may interact with diuretic medications and warrant monitoring for fluid balance in animals on diuretics. The formula is not appropriate for animals with spleen qi deficiency, cold patterns, or yin deficiency without active excess heat signs.

Medication categories warranting extra caution include anticoagulant and antiplatelet medications (Dang Gui's blood-invigorating properties), diuretic medications (the formula's multiple urination-promoting herbs), hepatic or renal medications requiring careful monitoring (given the formula's strong draining action and the Mu Tong ingredient), and immunosuppressive or anti-inflammatory medications (where the formula's fire-draining action may complement or interact with pharmaceutical treatments for inflammatory or immune-mediated conditions). Your authorizing veterinarian will determine appropriateness based on your animal's condition, current medications, TCVM pattern diagnosis, and renal and hepatic function assessment.

Frequently Asked Questions

What conditions is Long Dan Xie Gan San used for in TCVM?

In Traditional Chinese Veterinary Medicine, Long Dan Xie Gan San is indicated for two related presentations of liver-gallbladder excess: (1) liver and gallbladder repletion fire, presenting with irritability or agitation, redness or heat in the eyes or ears, headshaking, bitter taste or yellow mouth coatings, a red tongue with a yellow coating, and a wiry rapid pulse; and (2) liver and gallbladder damp-heat pouring downward into the lower burner, presenting with burning or frequent urination, urogenital inflammation or abnormal discharge, scrotal or vulvar damp-heat signs, a red tongue with a yellow greasy coating, and a slippery rapid pulse. Both presentations share the liver-gallbladder channel as the root of the excess, and the formula addresses both simultaneously through its fire-draining and damp-heat-draining herb groups. It is indicated for excess patterns only and is not appropriate for deficiency, cold, or mixed deficiency-excess patterns without veterinary confirmation of the active excess diagnosis.

How is Long Dan Xie Gan San administered to dogs, cats, and horses?

Mix the powder directly into food or grain at the dose recommended for your animal's species and body weight. 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. 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. Your authorizing veterinarian will confirm the appropriate dose, treatment duration, and monitoring plan for your individual animal given the formula's intensely draining composition, and will also assess renal and hepatic function as appropriate before beginning the treatment course.

How long does it take to see results with Long Dan Xie Gan San, and how long should it be used?

Because Long Dan Xie Gan San addresses active liver-gallbladder excess fire and damp-heat rather than a constitutional deficiency, response to treatment is typically seen relatively quickly - often within 1 to 3 weeks of consistent use as the excess fire is progressively drained and the damp-heat is cleared from the lower burner. The formula is not intended for indefinite long-term use due to its intensely bitter-cold and draining character; it is used until the active excess pattern is resolved, as confirmed by improvement in the fire and damp-heat signs and normalization of the tongue and pulse findings. Your veterinarian will monitor tongue quality, pulse, urinary signs, behavioral heat signs, and the overall fire-and-damp-heat pattern's resolution throughout the treatment course to determine the appropriate point at which to discontinue or transition to a maintenance formula.

How does Long Dan Xie Gan San differ from other TCVM formulas for liver heat and inflammatory conditions?

Long Dan Xie Gan San is specifically indicated for liver and gallbladder repletion fire and damp-heat - excess patterns with a red tongue, yellow or yellow greasy coating, and wiry rapid or slippery rapid pulse. It is not appropriate for liver qi stagnation without significant fire (where Xiao Yao San or Chai Hu Shu Gan San would be more appropriate), liver yin deficiency heat (where Zhi Bai Di Huang Wan would be more appropriate), or deficiency patterns where the bitter-cold draining herbs would further deplete the patient's constitutional resources. The formula's inclusion of Sheng Di Huang and Dang Gui to protect the yin and blood during the draining treatment is a critical safety feature that distinguishes it from simpler fire-draining formulas, but the yin-protecting herbs do not make it appropriate for deficiency-pattern presentations. Your authorizing veterinarian will confirm the correct TCVM excess pattern diagnosis before beginning the treatment course.
