Recommended by holistic veterinarians, Herbsmith Rx Peony Calm Shen is a Traditional Chinese Veterinary Medicine (TCVM) herbal formula that calms the Heart Shen, nourishes the Heart, soothes Liver Qi Stagnation, and nourishes Blood in dogs and cats presenting with the combined pattern of anxiety, fear, irritability, and aggression. In TCVM, anxiety and fear are the negative emotional expressions of a disturbed Heart Shen - the Heart's spirit or consciousness - while irritability and aggression are the negative emotional expressions of Liver imbalance, specifically Liver Qi Stagnation. It is not unusual in veterinary practice to see these two patterns together, because in the TCVM Five Element framework, the Liver (Wood element) generates and promotes the Heart (Fire element): Wood promotes Fire. When Liver Qi Stagnation is present - brought on by chronic stress, frustration, environmental toxins, or constitutional factors - the stagnant Liver Qi exerts an excessive promoting influence on the Heart, over-stimulating the Heart Fire and disturbing the Heart Shen. The result is the clinically common combination of the fear and anxiety of disturbed Heart Shen occurring simultaneously with the irritability and aggression of Liver Qi Stagnation - the pattern of the fear-aggressive dog. Peony Calm Shen addresses this combined pattern with a sixteen-herb strategy that calms and nourishes Heart Shen, soothes and regulates Liver Qi, and nourishes the Heart Blood and Yin that sustain calm Shen over time. Available in powder for dogs and cats (75g, 150g, 500g, 900g, 1200g). Dosing varies by body weight; your authorizing veterinarian will provide specific guidance.
Precaution: Not to be used in pregnant pets.

What It Supports
- Disturbed Heart Shen producing anxiety and fear: In TCVM, the Heart houses the Shen - the spirit, consciousness, and emotional stability of the animal; when the Heart Shen is disturbed, by excess Heart Fire, insufficient Heart Blood and Yin to anchor the Shen, or by the overflow of Liver Qi Stagnation into the Heart through the Wood-Fire relationship, the result is anxiety, fearfulness, restlessness, and emotional instability; calming and nourishing the Heart Shen is the primary treatment principle for the anxiety and fear dimension of the combined pattern.
- Liver Qi Stagnation producing irritability and aggression: In TCVM, the Liver is responsible for the smooth, unobstructed flow of Qi throughout the body and for the regulation of emotions; when Liver Qi becomes stagnant - through chronic stress, frustration, environmental toxins, or constitutional predisposition - the Liver loses its capacity for emotional regulation, and the stagnant Liver Qi generates irritability, frustration, and aggression; soothing the Liver and resolving Liver Qi Stagnation is the primary treatment principle for the irritability and aggression dimension of the combined pattern.
- Wood-promotes-Fire pathway: Liver Qi Stagnation over-stimulating Heart Shen: The simultaneous occurrence of Liver Qi Stagnation and Heart Shen disturbance in the fear-aggressive dog is explained by the Five Element Wood-promotes-Fire relationship: the Liver (Wood) normally generates and supports the Heart (Fire), but when Liver Qi is stagnant, this promoting relationship becomes excessive, and the stagnant Liver Qi overflows into the Heart channel, over-stimulating the Heart Fire and disturbing the Shen; the combined formula strategy of simultaneously resolving Liver Qi Stagnation and calming the Heart Shen addresses both the root (Liver Qi Stagnation) and the branch (disturbed Heart Shen) of this Five Element pattern.
- Heart Blood and Yin nourishment to anchor the Shen and sustain long-term emotional balance: In TCVM, the Heart Shen requires adequate Heart Blood and Yin as its material foundation - the Shen must be rooted in sufficient Heart substance to remain calm and stable; when Heart Blood or Yin is deficient, the Shen floats and becomes easily disturbed; nourishing Heart Blood and Yin through herbs like Suan Zao Ren, Bai Zi Ren, Mai Men Dong, Tian Men Dong, Dan Shen, and Dang Gui Tou addresses the foundational deficiency that makes the Heart Shen vulnerable to disturbance from the Liver Qi Stagnation.
TCVM Principles
- Primary action: Calm Heart Shen and clear excess Heart Fire agitating the Shen, nourish Heart Blood and Yin to provide the material foundation for stable Shen, soothe the Liver and resolve Liver Qi Stagnation to remove the root source of emotional dysregulation, regulate Liver Qi to restore smooth Qi flow through the emotional channels, and anchor the Shen through heavy-calming herbs that settle the rising Liver and Heart Fire.
- Approach: Peony Calm Shen addresses the clinically common combined pattern of Heart Shen disturbance and Liver Qi Stagnation through a sixteen-herb formula organized into four therapeutic layers. The first layer calms and anchors the Heart Shen directly: Suan Zao Ren, Bai Zi Ren, Fu Shen, and Yuan Zhi calm the Heart and anchor the Shen; Mu Li (calcined Oyster Shell) anchors the floating Shen through its heavy, settling nature. The second layer nourishes the Heart Blood and Yin that the Shen requires as its material foundation: Dan Shen, Dang Gui Tou, Mai Men Dong, Tian Men Dong, Xuan Shen, Ye Jiao Teng, and Bai Shao Yao nourish Heart Blood, Heart Yin, and Liver Blood and Yin, building the foundational substance that allows the Shen to remain stable and anchored. The third layer soothes and regulates the Liver to resolve the Liver Qi Stagnation that is over-stimulating the Heart through the Wood-Fire pathway: Chai Hu is the primary Liver Qi-soothing herb; Qing Pi and Xiang Fu Zi move Liver Qi and regulate the Liver's Qi-moving function; Bai Shao Yao nourishes Liver Blood and softens the Liver to prevent the Liver from constraining Qi. The fourth layer harmonizes the combined action: Wu Wei Zi consolidates Heart Qi and Yin, astringes the Shen to prevent dispersion, and harmonizes the Heart-Kidney axis that supports long-term Shen stability. Together, these four layers provide a comprehensive approach to the fear-aggressive pattern, addressing both the Heart Shen dimension and the Liver Qi dimension simultaneously.

Active Ingredient TCVM Actions
Peony Calm Shen is a sixteen-herb formula organized into four therapeutic layers: Heart Shen calming and anchoring, Heart Blood and Yin nourishment, Liver Qi soothing and regulation, and Shen consolidation and harmonization:
- Bai Shao Yao (Paeonia lactiflora, white) - White Peony root: The formula's namesake and a foundational herb serving dual functions in both the Liver-soothing and Blood-nourishing layers; nourishes Liver Blood and Yin, softens the Liver to prevent it from constraining Qi and over-promoting the Heart through the Wood-Fire pathway, calms Liver Yang rising, and harmonizes the Liver's Qi-moving function; the white preparation of Peony root is nourishing and astringent in nature (as opposed to the red preparation which is Blood-invigorating), making it appropriate for a formula requiring Liver nourishment alongside Liver Qi regulation; also nourishes Blood to support Heart Blood nourishment alongside Dan Shen and Dang Gui Tou.
- Bai Zi Ren (Platycladus orientalis, seed) - Biota seed: Nourishes Heart Blood, calms the Heart Shen, and moistens the intestines; one of the formula's primary Heart Blood-nourishing and Shen-calming herbs; Bai Zi Ren has a specific affinity for the Heart and is particularly indicated for Shen disturbance arising from Heart Blood deficiency; its rich, oily nature nourishes the Heart Blood from which the Shen draws its material foundation; also has a mild calming action that directly settles the Shen without sedating, making it appropriate for ongoing daily use in anxious animals.
- Chai Hu (Bupleurum chinense) - Bupleurum root: The formula's primary Liver Qi-soothing herb and the chief herb of the Liver-regulating layer; releases constrained Liver Qi, soothes the Liver, raises the clear Yang, and resolves the emotional stagnation of Liver Qi constraint; Chai Hu is one of the most important herbs in the TCVM materia medica for Liver Qi Stagnation and is the chief Liver-soothing herb in the classical formula Xiao Yao San (Free and Easy Wanderer), which is the foundational formula for the Liver Qi Stagnation pattern; its specific action of releasing Liver constraint is the direct therapeutic action for the irritability and aggression dimension of the fear-aggressive pattern; used in small amounts to soothe Liver Qi without overly ascending Yang.
- Dan Shen (Salvia miltiorrhiza) - Salvia root: Invigorates Blood, nourishes Heart Blood, clears Heart Heat, and calms the Heart Shen; serves dual Blood-nourishing and Heart-clearing functions; Dan Shen nourishes the Heart Blood that forms the material foundation of the Shen while simultaneously clearing the excess Heart Heat generated by the Liver Qi over-stimulating the Heart through the Wood-Fire pathway; one of the most important herbs in the TCVM materia medica for the combination of Heart Blood deficiency and disturbed Heart Shen with excess Heart Fire; its Heart-entering Blood-nourishing and Heat-clearing action directly addresses the Heart Shen disturbance at its source.
- Dang Gui Tou (Angelica sinensis, head) - Angelica root head: Nourishes and tonifies Liver and Heart Blood without strongly moving it; the head preparation is specifically tonifying rather than invigorating in nature; in a formula whose primary Blood strategy is nourishment rather than invigoration, the head preparation provides the deepest tonifying Blood action; nourishes the Heart Blood that anchors the Shen and the Liver Blood that prevents the Liver from becoming dry, constrained, and over-promoting toward the Heart.
- Fu Shen (Poria cocos, with pine root) - Poria with wood root: Calms the Heart Shen, quiets the spirit, tonifies Heart Qi, and is specifically indicated for the Shen-related presentations of anxiety, fearfulness, and restlessness; the preparation of Poria with the pine root (Fu Shen) is specifically Shen-calming, as distinct from plain Fu Ling which is more Spleen and Dampness-focused; Fu Shen is one of the most important Shen-calming herbs in the TCVM materia medica for Heart Qi and Blood deficiency with disturbed Shen, and its calming action is gentle and sustained, making it appropriate for ongoing daily Shen-calming support.
- Mai Men Dong (Ophiopogon japonicus) - Ophiopogon tuber: Nourishes Heart and Lung Yin, clears Heart Heat, and calms the Shen; the formula's primary Heart Yin-nourishing herb; as Heart Blood is the material foundation of the Shen at the Blood level, Heart Yin provides the deeper nourishing substrate at the Yin level; when Heart Yin is deficient, the Shen lacks the cool, moistening Yin substance it needs to remain calm and stable, and the Heart becomes susceptible to excess Heat from the over-stimulating Liver Qi; Mai Men Dong restores the Heart Yin that enables the Shen to remain anchored.
- Mu Li Shu (Ostrea gigas, calcined) - Calcined Oyster shell: Anchors the floating Yang and Shen, calms the Liver, and subdues Liver Yang rising; the formula's heavy-settling and Shen-anchoring herb; the calcined (shu) preparation of Oyster shell has a stronger anchoring and settling action than the raw form; Mu Li's heavy, mineral nature anchors the rising Liver Yang and floating Heart Shen that develop when Liver Qi Stagnation generates upward-rising Liver Yang that disturbs the Heart Shen; provides the settling, anchoring counterpart to the Liver-soothing and Blood-nourishing herbs, preventing the Yang from rising and agitating the Shen.
- Qing Pi (Citrus reticulata, green peel) - Green Tangerine peel: Breaks up Liver Qi Stagnation, disperses accumulations, and strongly moves Liver Qi; the green (immature) peel of Tangerine is more intensely Qi-moving than the ripe peel (Chen Pi) and has a specific affinity for the Liver and Gallbladder channels; Qing Pi's strong Liver Qi-dispersing action complements Chai Hu's Liver Qi-soothing action - Chai Hu soothes and releases constrained Liver Qi, while Qing Pi breaks up the more stubborn Qi accumulations in the Liver channel; together they provide a comprehensive Liver Qi-resolving strategy addressing both the gentler and more established dimensions of Liver Qi Stagnation.
- Suan Zao Ren (Ziziphus spinosa, seed) - Sour Jujube seed: The most important single herb in the TCVM materia medica for Heart Blood deficiency with disturbed Shen; nourishes Heart Blood, calms the Shen, prevents excessive sweating, and specifically treats the restlessness and anxiety of Heart Blood deficiency; Suan Zao Ren is the chief herb of the classical formula Suan Zao Ren Tang, one of the foundational TCVM formulas for Shen disturbance arising from Heart Blood deficiency; its dual action of nourishing the Heart Blood and calming the Shen directly addresses both the material foundation of Shen stability and the Shen disturbance itself.
- Tian Men Dong (Asparagus cochinchinensis) - Asparagus tuber: Nourishes Kidney and Lung Yin, clears Heat, and generates fluids; the formula's Kidney Yin-nourishing herb and a complement to Mai Men Dong in the Yin-nourishing strategy; the Heart-Kidney axis is fundamental to long-term Shen stability in TCVM: the Kidneys provide the cool Water that controls the Heart Fire from below; when Kidney Yin is deficient, the Kidney Water cannot adequately cool and anchor the Heart Fire, and the Heart Shen becomes disturbed from below; Tian Men Dong nourishes the Kidney Yin that sustains the Heart-Kidney cooling relationship, supporting long-term Shen stability at the constitutional level.
- Wu Wei Zi (Schisandra chinensis) - Schisandra fruit: Astringes and consolidates the Heart Qi and Yin, prevents the Shen from dispersing, tonifies the Kidney and Heart, and harmonizes the Heart-Kidney axis; the formula's Shen-consolidating and harmonizing herb; Wu Wei Zi's astringent nature prevents the dispersal of Heart Qi and Yin that occurs when the Shen is chronically disturbed, preserving the Heart substance that the Shen requires; its five-flavor nature and Heart-Kidney-entering character specifically harmonize the Heart-Kidney axis, supporting the Water-Fire balance that is fundamental to sustained emotional stability in TCVM.
- Xiang Fu Zi (Cyperus rotundus) - Cyperus rhizome: Soothes the Liver, moves Liver Qi, and is one of the most important herbs in the TCVM materia medica for Liver Qi Stagnation with emotional dysregulation; known as the "primary herb for Qi" in classical TCVM texts because of its broad Qi-regulating action; Xiang Fu Zi's specific Liver Qi-moving action addresses the fundamental Qi constraint that underlies the Liver Qi Stagnation pattern, working alongside Chai Hu and Qing Pi to provide a three-herb Liver Qi-resolving strategy that addresses Liver Qi Stagnation from multiple angles.
- Xuan Shen (Scrophularia ningpoensis) - Scrophularia root: Nourishes Yin, clears Heat, and cools the Blood; adds a Yin-nourishing and Heat-clearing dimension to the formula's Blood and Yin nourishment strategy; Xuan Shen's cooling and Yin-nourishing action helps counteract the excess Heart Heat generated by Liver Qi over-stimulating the Heart through the Wood-Fire pathway, and replenishes the Yin substance depleted by chronic Heat in the Heart and Liver channels.
- Ye Jiao Teng (Polygonum multiflorum, vine) - Polygonum multiflorum vine: Nourishes Heart Blood, calms the Shen, opens channels, and promotes sleep; the vine of the He Shou Wu plant (Polygonum multiflorum), which has a specific Heart Blood-nourishing and Shen-calming action; Ye Jiao Teng is particularly indicated for the anxious, restless animal that has difficulty settling or sleeping due to disturbed Heart Shen from Heart Blood deficiency; its Blood-nourishing and channel-opening action extends the formula's Shen-calming effect through the channels, ensuring the nourishing herbs reach the Heart and associated tissues.
- Yuan Zhi (Polygala tenuifolia) - Polygala root: Calms the Shen, opens the Heart orifices, expels Phlegm from the Heart, and strengthens the Heart-Kidney communication; one of the most important herbs in TCVM for the combination of Heart Shen disturbance and disturbed Heart-Kidney communication; Yuan Zhi opens the Heart orifices that become obstructed when Phlegm accumulates in the Heart from chronic Liver Qi Stagnation, and strengthens the communication between the Heart (Fire above) and the Kidneys (Water below) that is fundamental to long-term Shen stability; also directly calms the Shen and is specifically indicated for anxiety, fearfulness, and emotional instability.
Potential Drug Interactions
Herbsmith Rx Peony Calm Shen contains Dan Shen (Salvia miltiorrhiza), which has well-documented effects on hepatic drug metabolism (CYP enzyme pathways) and Blood-invigorating properties, Dang Gui Tou (Angelica sinensis) with mild Blood-nourishing and moving properties, and Chai Hu (Bupleurum), which has immune-modulating and hepatic properties.

Frequently Asked Questions
What is the "fear-aggressive" pattern in TCVM, and why does this formula specifically address it?
Fear aggression in TCVM is the clinical expression of a combined Heart Shen and Liver Qi pattern: the fear and anxiety come from disturbed Heart Shen, while the irritability and aggression come from Liver Qi Stagnation. This pattern is particularly common and clinically important because of the Five Element Wood-promotes-Fire relationship between the Liver and Heart. When Liver Qi becomes stagnant - as it commonly does in today's animals under chronic stress, environmental pressure, and constitutional strain - the stagnant Liver Qi exerts an exaggerated promoting influence on the Heart through the Wood-Fire pathway, over-stimulating the Heart Fire and disturbing the Heart Shen. The result is the simultaneous presentation of Liver-driven irritability and aggression alongside Heart-driven fear and anxiety that characterizes fear aggression. Standard anxiety formulas that only calm the Heart Shen do not resolve the Liver Qi Stagnation root, and the Heart Shen disturbance tends to recur. Peony Calm Shen addresses both the Heart Shen branch and the Liver Qi Stagnation root simultaneously, making it the appropriate formula for the combined fear-aggressive pattern rather than anxiety or aggression alone.
How is Peony Calm Shen administered, and what are the recommended doses?
Mix the powder directly into your pet's food twice daily. For dogs: under 15 lbs, give 1/4 teaspoon twice daily; 15-30 lbs, give 1/2 teaspoon twice daily; 31-80 lbs, give 1 teaspoon twice daily; 81-120 lbs, give 1-1/2 teaspoons twice daily; over 120 lbs, give 2 teaspoons twice daily. For cats: give 1/4 teaspoon twice daily. Administer as prescribed by your authorizing veterinarian, who may adjust dosing based on your pet's specific pattern and response. Do not use this formula in pregnant pets.
How long does it take to see results with Peony Calm Shen?
Because this formula addresses constitutional Heart Blood deficiency and Liver Qi Stagnation alongside the behavioral expressions of those patterns, meaningful improvement typically requires consistent twice-daily use over 4 to 8 weeks. Some animals with milder or more recently established patterns may show earlier signs of improved emotional regulation - reduced reactivity, greater ease of settling, and softened fear responses - within 2 to 4 weeks. Animals with long-standing, deeply established Liver Qi Stagnation and Heart Blood deficiency patterns may require longer sustained use, as restoring adequate Heart Blood and resolving chronic Liver Qi constraint is a gradual constitutional process. Because the underlying patterns (chronic stress, constitutional Liver Qi Stagnation, Heart Blood deficiency) are often persistent, ongoing long-term use is frequently appropriate for continued behavioral and emotional support. Your authorizing veterinarian can monitor your pet's response and adjust dosing or duration as needed.
Can Peony Calm Shen be used alongside pharmaceutical behavioral or anxiety medications?
This is an important safety question that requires veterinary supervision. Several of this formula's herbs - particularly Dan Shen (Salvia miltiorrhiza) and Chai Hu (Bupleurum) - have documented effects on hepatic drug-metabolizing enzyme pathways (CYP450 enzymes) that can affect the blood levels of pharmaceutical medications metabolized through those pathways. Additionally, the Shen-calming herbs in this formula may potentiate the sedative effects of pharmaceutical anxiolytics or sedatives. Dan Shen specifically has well-documented interactions with warfarin and cardiac glycosides. This does not mean the formula cannot be used alongside conventional behavioral management - many dogs and cats benefit from integrative TCVM and pharmaceutical approaches together - but concurrent use requires active veterinary oversight and medication monitoring, particularly during the initial combination period. Your authorizing veterinarian can determine the safest and most effective integrative protocol for your pet's specific medications and behavioral management plan.
