Active Ingredient TCVM Actions
Long Dan Xie Gan Tang is a ten-herb formula structured around a potent Liver Fire and Damp-Heat-draining core, with Liver-soothing, Blood-nourishing, and fluid-promoting deputies to drain excess Heat and Damp-Heat downward while protecting Yin and Blood:
- Long Dan Cao (Gentiana scabra), Chinese gentian root: The chief herb; powerfully drains Liver and Gallbladder Fire, clears Damp-Heat from the Liver and lower Jiao, and is the primary Heat-clearing and Damp-draining herb in the formula.
- Huang Qin (Scutellaria baicalensis), Scutellaria root: Clears Heat, dries Dampness, and drains Fire from the upper and middle Jiao; supports Long Dan Cao in clearing Liver and Gallbladder Heat.
- Zhi Zi (Gardenia jasminoides), Gardenia fruit: Clears Heat, drains Fire, and promotes urination to guide Heat downward and out through the Bladder; supports the formula's Heat-draining action.
- Ze Xie (Alisma orientalis), Alisma rhizome: Drains Dampness, promotes urination, and clears Damp-Heat from the lower Jiao; guides Damp-Heat downward and out through the Bladder.
- Che Qian Zi (Plantago asiatica), Plantain seed: Promotes urination, clears Heat, and drains Damp-Heat from the lower Jiao; supports Ze Xie in draining Dampness downward.
- Tong Cao (Tetrapanax papyrifer), Rice paper pith: Promotes urination, clears Heat, and supports the formula's Damp-draining action through the Bladder and lower Jiao.
- Chai Hu (Bupleurum chinense), Bupleurum root: Soothes Liver Qi, relieves stagnation, and guides the formula's actions to the Liver and Gallbladder channels; prevents the strong draining herbs from over-suppressing Liver Qi.
- Dang Gui (Angelica sinensis), Dong quai root: Nourishes and invigorates Blood; prevents the strong Heat-clearing and Damp-draining herbs from damaging Blood and Yin.
- Sheng Di Huang (Rehmannia glutinosa, raw), Raw rehmannia root: Clears Heat, cools Blood, and nourishes Yin; protects Yin and Blood from the draining action of the chief and deputy herbs.
- Gan Cao (Glycyrrhiza uralensis), Licorice root: Tonifies Spleen Qi, harmonizes the formula, and moderates the actions of the stronger Heat-clearing and Damp-draining herbs.
Potential Drug Interactions
Long Dan Xie Gan Tang contains potent Heat-clearing and Damp-draining herbs (Long Dan Cao, Huang Qin, Zhi Zi, Ze Xie, Che Qian Zi, Tong Cao) alongside a Liver Qi-soothing herb (Chai Hu) and Blood-nourishing herbs (Dang Gui, Sheng Di Huang) that may interact with certain medications. This is a strong draining formula; use with caution in patients with Qi Deficiency. Pets 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 diuretic medications, hepatic medications, anticoagulant or antiplatelet medications, and pets managing multiple concurrent prescriptions. Your veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

Frequently Asked Questions
What conditions is Long Dan Xie Gan used for in TCVM?
Long Dan Xie Gan is most commonly recommended for dogs, cats, and horses with TCVM patterns of excess Liver Fire or Damp-Heat in the Liver, Gallbladder, and lower Jiao. Holistic veterinarians frequently prescribe it for pets with eye and ear conditions, skin conditions, or lower Jiao patterns rooted in Liver Heat or Damp-Heat accumulation. The manufacturer lists no contraindications for this formula, but use caution in patients with Qi Deficiency, as the strong draining herbs may further weaken Qi.
How is Long Dan Xie Gan administered, and what are the recommended doses?
Dosing varies by species, body weight, and health condition; your authorizing veterinarian will determine the appropriate dose following a TCVM evaluation. For dogs and cats using 0.5g concentrated capsules, the general guideline is one capsule per 20 to 40 lbs of body weight twice daily. For small dogs and cats under 10 lbs, one 0.2g capsule once daily is typical. For the 90g concentrated powder, the dose for dogs and cats is 0.1g to 0.25g per 10 to 20 lbs twice daily; the included small scoop holds approximately 0.3g, and the large scoop holds approximately 1.2g. For horses, the standard dose is 3g (approximately 2.5 large scoops) twice daily.
How long does it take to see results with Long Dan Xie Gan, and how long can it be used?
The manufacturer recommends use for up to 3 months. As a strong draining formula, Long Dan Xie Gan is typically used for shorter courses to address acute or active Liver Heat and Damp-Heat patterns, rather than for long-term maintenance. Regular follow-up with your holistic veterinarian is recommended to monitor progress, assess the pattern, and adjust dosing or transition to a maintenance formula as needed.
Can Long Dan Xie Gan be combined with other TCVM formulas or medications?
Long Dan Xie Gan is sometimes used alongside other TCVM formulas as part of a comprehensive Liver Heat or Damp-Heat support protocol, but your authorizing veterinarian should always guide combination use. Use with caution in patients with Qi Deficiency. If your pet is on prescription medications, particularly diuretics or hepatic medications, your veterinarian will evaluate whether Long Dan Xie Gan is appropriate given your pet's full health picture and current treatment plan.
