Active Ingredient TCVM Actions
Zhen Xin San is a twelve-herb formula combining potent Heat-clearing, Fire-draining, and Phlegm-transforming herbs with Shen-calming, Qi-tonifying, Dampness-draining, and Wind-Phlegm-dispersing agents to address Heart Fire and Phlegm-Heat patterns with Shen disturbance:
- Huang Lian (Coptis chinensis), Coptis rhizome: The most potent Heat-clearing and Fire-draining herb in the Chinese materia medica; clears Heart Fire, drains Stomach Fire, and resolves toxins; the primary Heart Fire-clearing herb and the formula's chief herb for addressing the Fire and Heat component of the pattern.
- Huang Qin (Scutellaria baicalensis), Scutellaria root: Clears Heat, drains Fire, and resolves toxins from the upper and middle Jiao; works with Huang Lian as the primary Heat-clearing and Fire-draining pair, addressing the Heat component across the upper and middle Jiao channels.
- Zhi Zi (Gardenia jasminoides), Gardenia fruit: Clears Heat, drains Fire, resolves toxins, and drains Damp-Heat through the urine; works with Huang Lian and Huang Qin as the primary Heat-clearing and Fire-draining trio, completing the formula's potent Heat-clearing base.
- Tian Nan Xing (Arisaema erubescens), Arisaema rhizome: Dries Dampness, transforms Phlegm, disperses Wind-Phlegm, and opens the orifices; the primary Phlegm-transforming and Wind-Phlegm-dispersing herb, addressing the Phlegm component of the pattern and the Wind-Phlegm that can arise when Phlegm obstructs the channels.
- Ban Xia (Pinellia ternata), Pinellia rhizome: Dries Dampness, transforms Phlegm, descends rebellious Qi, and harmonizes the Stomach; works with Tian Nan Xing as the primary Phlegm-transforming pair, addressing the Phlegm accumulation in the channels and the Stomach Qi rebellion accompanying Phlegm-Heat.
- Zhu Ru (Bambusa tuldoides), Bamboo shavings: Clears Heat, transforms Phlegm-Heat, and calms the Shen; the primary Phlegm-Heat-clearing herb, specifically addressing the Phlegm-Heat component of the pattern and contributing to the formula's Shen-calming action.
- Yu Jin (Curcuma aromatica), Curcuma tuber: Invigorates Blood, moves Qi, clears Heat, and opens the Heart orifice; the primary orifice-opening and Qi-invigorating herb, addressing the Phlegm-Heat obstruction of the Heart orifice and supporting the Shen-calming herbs by clearing the obstruction that disturbs the Shen.
- Yuan Zhi (Polygala tenuifolia), Polygala root: Calms the Shen, quiets the spirit, opens the Heart orifice, and transforms Phlegm; the primary Shen-calming and orifice-opening herb, working with Yu Jin to clear the Phlegm obstruction from the Heart orifice and calm the disturbed Shen.
- Jiang Can (Bombyx mori, with Beauveria bassiana), Silkworm with fungus: Disperses Wind-Phlegm, resolves toxins, and calms spasms and tremors; an animal-derived ingredient that addresses the Wind-Phlegm component of the pattern, particularly the spasms, tremors, and convulsive signs that can arise when Phlegm-Heat generates internal Wind.
- Fang Feng (Saposhnikovia divaricata), Ledebouriella root: Disperses Wind, releases the exterior, and addresses Wind-Phlegm in the channels; works with Jiang Can to address the Wind-Phlegm component of the pattern, dispersing Wind from the channels and supporting the formula's action on Wind-Phlegm-related behavioral and neurological signs.
- Fu Ling (Poria cocos), Poria mushroom: Tonifies Spleen Qi, calms the Shen, and drains Dampness; supports the Spleen's transforming and transporting functions to prevent further Phlegm generation, contributes to the formula's Shen-calming action, and drains the Dampness underlying the Phlegm accumulation.
- Dang Shen (Codonopsis pilosula), Codonopsis root: Tonifies Spleen and Lung Qi and nourishes Blood; supports the Spleen Qi-tonifying action of Fu Ling and provides the Qi-tonifying foundation to sustain the formula's strong Heat-clearing and Phlegm-transforming actions without depleting the Zheng Qi.
Potential Drug Interactions
Zhen Xin San contains potent Heat-clearing and Fire-draining herbs (Huang Lian, Huang Qin, Zhi Zi) alongside Phlegm-transforming herbs (Tian Nan Xing, Ban Xia, Zhu Ru) and Shen-calming and orifice-opening herbs (Yu Jin, Yuan Zhi, Jiang Can) that may interact with certain medications. Stop administration immediately if the patient develops diarrhea, vomiting, or other unusual signs. 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 sedative or anxiolytic medications, anticonvulsant medications, cardiac medications, and pets managing multiple concurrent prescriptions. The manufacturer recommends use for up to 6 months. Your veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

Frequently Asked Questions
What conditions is Zhen Xin San used for in TCVM?
Zhen Xin San is most commonly recommended for dogs, cats, and horses with TCVM patterns of Heart Fire and Phlegm-Heat with Shen disturbance, where Phlegm-Heat accumulation obstructs the Heart orifice and disturbs the Shen, leading to restlessness, anxiety, behavioral signs, or neurological signs associated with Wind-Phlegm. Holistic veterinarians frequently prescribe it for pets with behavioral or neurological patterns rooted in Heart Fire and Phlegm-Heat, including signs of Shen disturbance with a Phlegm-Heat component. The manufacturer lists no contraindications for this formula.
How is Zhen Xin San 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 concentrated 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 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. Stop administration immediately if the patient develops diarrhea, vomiting, or other unusual signs. The manufacturer recommends use for up to 6 months.
What is the significance of the classical source Yuan Heng Liao Ma Ji for this formula?
Yuan Heng Liao Ma Ji (Yuan-heng's Therapeutic Treatise of Horses) is one of the most important classical texts in traditional Chinese veterinary medicine, written by Yu Benyuan and Yu Benheng in 1608 during the Ming dynasty. The text is specifically an equine veterinary treatise, and Zhen Xin San was originally formulated for horses experiencing Heart Fire and Phlegm-Heat patterns with Shen disturbance. In modern TCVM practice, the formula has been adapted for use in dogs and cats as well, reflecting the broader application of classical equine formulas across companion animal species when the underlying TCVM pattern is the same.
Why does Zhen Xin San contain Wind-dispersing herbs like Fang Feng and Jiang Can?
In TCVM, Phlegm obstructing the channels and orifices can generate internal Wind, leading to spasms, tremors, convulsive signs, or erratic behavioral signs alongside the Shen disturbance. Fang Feng and Jiang Can are included in Zhen Xin San to address this Wind-Phlegm component of the pattern. Jiang Can specifically disperses Wind-Phlegm and calms spasms, making it particularly relevant for patterns where Phlegm-Heat has generated Wind signs. Fang Feng supports the Wind-dispersing action and helps clear Wind from the channels. Their inclusion reflects the formula's comprehensive approach to Phlegm-Heat patterns that have progressed to involve Wind-Phlegm and neurological or convulsive signs.
