Recommended by holistic veterinarians, Herbsmith Rx Codonopsis Harmonize Qi is a Traditional Chinese Veterinary Medicine (TCVM) herbal formula designed to support Wei Qi (pronounced "way chee") - the body's defensive Qi - in dogs and cats. A remarkably focused two-herb formula, it pairs Huang Qi (Astragalus) and Dang Shen (Codonopsis root), the classic combination for tonifying Spleen and Lung Qi and building Wei Qi from its foundational source. In TCVM, Wei Qi is the body's primary line of defense against external pathogens; bacteria and viruses are opportunistic and can invade the body only when Wei Qi is insufficient to repel them. The root of all Qi in the body is the Stomach and Spleen: the Stomach breaks down food, and the Spleen absorbs and distributes nutrients throughout the body, generating Qi from the food Essence it processes. Huang Qi and Dang Shen together strengthen this Spleen-Stomach Qi production axis, support the Lung's role in dispersing Wei Qi to the body surface, tonify Blood alongside Qi, and build the overall level of Wei Qi that keeps the body healthy and resistant to external challenge. Available as a powder for dogs and cats, and as tablets for dogs. Dosing varies by body weight; your authorizing veterinarian will provide specific guidance.

What It Supports
- Wei Qi (defensive Qi) support through Spleen and Lung Qi tonification: Builds Wei Qi from its constitutional root by tonifying the Spleen-Stomach Qi production axis that generates all Qi in the body; Huang Qi specifically disperses the generated Qi outward to the body surface as Wei Qi, maintaining the body's defensive barrier against external pathogens.
- Spleen and Stomach function to maximize nutrient utilization and Qi development: Supports the Spleen's ability to absorb and transform food nutrients into usable Qi and Blood; when the Spleen and Stomach function optimally, the body generates the Qi it needs to power all physiological functions, including the production and circulation of Wei Qi; when Spleen Qi is deficient, Qi and Blood production decline, Wei Qi weakens, and the body becomes susceptible to external pathogens.
- Blood tonification alongside Qi tonification: Both Huang Qi and Dang Shen tonify Blood alongside Qi; in TCVM, Qi and Blood are mutually generated and interdependent; tonifying both ensures the complete nourishing-and-energizing foundation the body needs to maintain robust Wei Qi and overall health.
- Long-term constitutional immune resilience: Through consistent daily use, supports the body's innate ability to keep itself healthy by maintaining Qi and Wei Qi at levels sufficient to resist opportunistic pathogen invasion; appropriate for ongoing use as a constitutional Qi tonic in animals with recurrent susceptibility to illness, post-illness recovery, or as a preventive support during seasonal or environmental immune challenges.
TCVM Principles
- Primary action: Tonify Spleen and Lung Qi, build Wei Qi, support Stomach and Spleen function for optimal nutrient utilization and Qi development, and tonify Blood alongside Qi to maintain the body's constitutional health and resistance to external pathogens.
- Approach: From a TCVM perspective, Wei Qi is the body's defensive Qi - its first line of defense against external pathogens, including bacteria, viruses, and environmental challenges. Bacteria and viruses are opportunistic: they invade the body not simply because they are present in the environment, but because the body's Wei Qi is insufficient to repel them. A robust Wei Qi keeps the body's exterior closed to pathogenic invasion; a deficient Wei Qi leaves the exterior open and susceptible. Wei Qi has its root in the functioning of the Spleen and Stomach. The Stomach receives and breaks down food; the Spleen absorbs the resulting food Essence and transforms it into Qi and Blood, then distributes them throughout the body. The Lung receives the Qi produced by the Spleen and disperses it outward to the body surface as Wei Qi. When the Spleen-Stomach axis functions optimally, Qi and Blood are generated in abundance, the Lung disperses strong Wei Qi to the surface, and the body maintains robust resistance to external challenges. When Spleen Qi is deficient, the entire chain weakens: Qi and Blood production decline, the Lung has insufficient Qi to disperse, Wei Qi thins, and the body becomes susceptible to opportunistic pathogens. Huang Qi and Dang Shen address this foundational mechanism directly: Huang Qi tonifies Spleen and Lung Qi and specifically strengthens and disperses Wei Qi to the exterior; Dang Shen tonifies Spleen and Stomach Qi and generates Qi and Blood from the middle Jiao. Together they constitute the core of the classical Wei Qi-building strategy, making Codonopsis Harmonize Qi a foundational constitutional tonic for animals with Qi deficiency and insufficient Wei Qi.

Active Ingredient TCVM Actions
Codonopsis Harmonize Qi is a two-herb formula representing the classical core of TCVM Wei Qi tonification. Each herb addresses the foundational mechanism of Wei Qi production from a complementary angle - Huang Qi from the Lung and exterior-dispersing direction, Dang Shen from the Spleen-Stomach and middle Jiao direction - and together they address the complete Spleen-Lung-Wei Qi production and dispersal axis:
- Huang Qi (Astragalus membranaceus) - Astragalus root: The formula's primary Wei Qi-building herb and one of the most important Qi tonics in the entire TCVM materia medica; tonifies Spleen and Lung Qi, raises Spleen Yang, and specifically strengthens and disperses Wei Qi to the body's exterior surface; Huang Qi's ability to consolidate the exterior and strengthen the Wei Qi's defensive function at the body surface is unique among Qi tonics and is the primary reason it is the leading herb for immune support in TCVM; also tonifies Blood alongside Qi, promotes the generation of body fluids, and supports the healing of tissues; particularly appropriate for animals with recurrent susceptibility to external pathogens, post-illness Wei Qi deficiency, or constitutional Qi weakness manifesting as easy fatigue, soft muscles, or poor recovery from illness.
- Dang Shen (Codonopsis pilosula) - Codonopsis root: The formula's Spleen and Stomach Qi tonic, tonifying the middle Jiao foundation from which all Qi and Blood are generated; Dang Shen is often used as the gentler alternative to Ren Shen (Ginseng) for Spleen and Lung Qi tonification, making it appropriate for long-term daily constitutional use without the stimulating properties of Ginseng; tonifies Spleen and Stomach Qi to support optimal nutrient absorption and transformation, nourishes Blood alongside Qi generation, and supports the Lung Qi that the Spleen sends upward for Wei Qi dispersal; particularly appropriate for animals showing Spleen Qi deficiency signs including soft stools, poor appetite, easy fatigue, and muscle weakness alongside the immune susceptibility; together with Huang Qi, Dang Shen completes the Spleen-Stomach-Lung-Wei Qi production chain that is the constitutional root of immune resilience in TCVM.
Potential Drug Interactions
Herbsmith Rx Codonopsis Harmonize Qi contains Huang Qi (Astragalus), which has well-documented immune-modulating properties, and Dang Shen (Codonopsis), which tonifies Qi and Blood and supports Spleen and Stomach function. Both herbs are considered gentle and well-tolerated for long-term use. Dogs and cats on prescription medications should use this formula under veterinary supervision.
Medication categories warranting extra caution include immunosuppressive medications (Huang Qi's immune-tonifying properties may theoretically interact with immunosuppressive drugs such as corticosteroids, cyclosporine, or other immunosuppressants used for immune-mediated conditions; concurrent use should be coordinated with your veterinarian), anticoagulant medications (Huang Qi may have mild effects on platelet aggregation at high doses; concurrent use with anticoagulants warrants veterinary monitoring), and animals on multiple concurrent prescription medications. Your veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

Frequently Asked Questions
What is Wei Qi, and why is it important for my pet's health?
Wei Qi (pronounced "way chee") is the body's defensive Qi in Traditional Chinese Veterinary Medicine - the equivalent of the immune system's frontline defense against external pathogens. Wei Qi circulates at the body's surface and in the spaces between the skin and muscles, where it warms the body, closes the pores against pathogenic invasion, and repels external pathogens before they can penetrate deeper. From a TCVM perspective, bacteria and viruses are opportunistic: they invade the body not simply because they are encountered in the environment, but because the Wei Qi is insufficient to repel them. A robust Wei Qi keeps the exterior closed; a deficient Wei Qi leaves the body open to pathogenic invasion and recurrent illness. Wei Qi is generated by the Spleen and Stomach processing food nutrients and is dispersed to the surface by the Lung. Codonopsis Harmonize Qi supports the Wei Qi by tonifying the Spleen-Stomach-Lung axis that produces and disperses it.
How is Codonopsis Harmonize Qi administered, and what are the recommended doses?
For the powder, mix directly into your pet's food twice daily. For dogs: under 30 lbs, give 1/2 teaspoon twice daily; 30-80 lbs, give 1 teaspoon twice daily; 80-120 lbs, give 1-1/2 teaspoons twice daily; over 120 lbs, give 2 teaspoons twice daily. For cats: give 1/4 teaspoon twice daily. For tablets (dogs only): under 10 lbs, give 1/2 tablet twice daily; 11-30 lbs, give 1 tablet twice daily; 31-50 lbs, give 2 tablets twice daily; 51-80 lbs, give 3 tablets twice daily; over 80 lbs, give 4 tablets twice daily. Administer as prescribed by your authorizing veterinarian, who may adjust dosing based on your pet's specific pattern and response.
Is this formula appropriate for ongoing daily use, or is it intended for short-term use?
Codonopsis Harmonize Qi is specifically designed as a constitutional Qi tonic for long-term daily use. Because it addresses a foundational Qi deficiency pattern rather than an acute condition, it works best when used consistently over weeks to months, allowing the Spleen, Lung, and Wei Qi to build gradually from their root. Animals with recurrent susceptibility to illness, animals in post-illness recovery, older animals with declining constitutional Qi, and animals in environments with high pathogen exposure or significant seasonal immune challenges all benefit from consistent daily use. This formula is gentle and well-tolerated for extended use. Your authorizing veterinarian can advise on duration and any monitoring appropriate to your pet's specific situation.
Why does this formula have only two herbs when most TCVM formulas have many more?
The two-herb composition of Codonopsis Harmonize Qi reflects a classical TCVM strategy of targeting the foundational mechanism precisely and directly rather than building a complex multi-herb formula. Huang Qi and Dang Shen are the core of Wei Qi tonification in TCVM: Huang Qi directly builds and disperses Wei Qi to the exterior, and Dang Shen tonifies the Spleen-Stomach Qi production foundation from which all Wei Qi is generated. Together they address the complete Spleen-Lung-Wei Qi production and dispersal chain with nothing extraneous. The simplicity of this formula is a clinical strength, not a limitation: it allows the two herbs to work at full concentration on the specific mechanism being addressed. It minimizes the potential for herb-herb or herb-drug interactions, and it makes the formula appropriate for long-term daily constitutional use without the complexity management required by larger formulas.
