Also known as Agastache Powder to Rectify the Qi or the Agastache Combination, this eleven-herb formula from the Song dynasty Imperial Grace Formulary (Tai Ping Hui Min He Ji Ju Fang, 1107 CE) addresses the summerheat-dampness pattern where external wind-cold or summerheat combines with internal dampness to disrupt the middle jiao, producing turbid dampness disturbing the spleen and stomach, stomach qi ascending counterflow, and the characteristic digestive and systemic signs of the summerheat-dampness pattern. The eponymous principal herb Huo Xiang (agastache, 15% of the formula) is the only classical herb that simultaneously releases the exterior pathogenic factor, transforms the internal middle jiao dampness, harmonizes the stomach, and redirects ascending stomach qi counterflow, making it uniquely suited as the lead herb for the combined exterior-interior summerheat-dampness presentation. The remaining ten herbs provide targeted exterior release (Zi Su Ye, Bai Zhi), middle jiao qi-regulating and dampness-transforming coverage (Hou Po, Chen Pi, Ban Xia, Da Fu Pi), spleen qi-strengthening and dampness-transforming support (Bai Zhu, Fu Ling), lung qi-diffusing direction (Jie Geng), and harmonization (Zhi Gan Cao). Well suited for dogs, cats, and horses presenting with the summerheat-dampness pattern, characterized by turbid dampness disturbing the middle jiao with loose stools or digestive upset from dampness accumulation, nausea and stomach qi ascending counterflow (expressed as vomiting or regurgitation in animals), abdominal distension and fullness from dampness obstructing the middle jiao qi, simultaneous exterior signs of mild chills, a pale or slightly red tongue with a thick white or greasy coating reflecting the dampness pattern, and a soft or slippery pulse. 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eVETERINARY AUTHORIZATION REQUIRED: \u003ca href=\"https:\/\/tcvmpet.com\/pages\/get-an-authorization\" rel=\"noopener\" style=\"color: rgb(0, 0, 0);\" target=\"_blank\"\u003eSubmit Your Authorization Request\u003c\/a\u003e or \u003ca href=\"https:\/\/tcvmpet.com\/pages\/schedule-a-consultation\" rel=\"noopener\" style=\"color: rgb(0, 0, 0);\" target=\"_blank\"\u003eRequest a TCVM Telemedicine Consultation\u003c\/a\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eWhat It Supports\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul style=\"text-align: left;\"\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eSimultaneous exterior release and internal dampness transformation through Huo Xiang as the lead herb addressing both pathogenic layers of the summerheat-dampness pattern:\u003c\/strong\u003e Addresses the combined exterior-interior pathogenic factor pattern of summerheat-dampness through Huo Xiang's (agastache\/patchouli) unique dual action of releasing the exterior wind-cold or summerheat pathogenic factor and simultaneously transforming the internal middle jiao dampness that has combined with the exterior factor to create the summerheat-dampness pattern. Huo Xiang is positioned as the lead herb at 15% of the formula because no other single herb in the classical materia medica addresses both the exterior pathogenic factor and the internal dampness simultaneously; all other herbs in the formula address one or the other. Huo Xiang also harmonizes the stomach and redirects the ascending stomach qi counterflow expressed as nausea, vomiting, or regurgitation in animals, providing direct stomach-harmonizing coverage alongside its exterior-releasing and dampness-transforming action.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eExterior wind-cold release and dampness drying through Zi Su Ye and Bai Zhi to support Huo Xiang's exterior-releasing action:\u003c\/strong\u003e Provides additional exterior wind-cold-releasing and aromatic dampness-drying action through Zi Su Ye (perilla leaf, which releases exterior wind-cold, moves the qi, and harmonizes the middle jiao) and Bai Zhi (Dahurian angelica root, which releases exterior wind-cold, dries dampness from the upper body and nasal passages, and disperses the exterior dampness accumulation). Together, Zi Su Ye and Bai Zhi reinforce Huo Xiang's exterior-releasing action and extend the formula's aromatic dampness-drying coverage to the exterior channels and upper body, ensuring the external pathogenic factor component of the summerheat-dampness pattern is cleared alongside the internal dampness transformation.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eMiddle jiao qi regulation, dampness transformation, and stomach qi counterflow redirection through the four-herb dampness-regulating and qi-descending group:\u003c\/strong\u003e Regulates the middle jiao qi, transforms internal dampness, and redirects the ascending stomach qi counterflow through four complementary herbs: Hou Po (magnolia bark, descends qi, transforms dampness, relieves the abdominal fullness and distension from dampness obstructing the middle jiao qi), Chen Pi (aged tangerine peel, moves qi, dries dampness, harmonizes the middle jiao), Ban Xia (pinellia rhizome, transforms dampness and phlegm, descends the stomach qi counterflow as the primary herb for stomach qi ascending counterflow with dampness, and dries the middle jiao dampness), and Da Fu Pi (betel husk, moves qi downward, transforms dampness, relieves the abdominal distension and fullness).

The spleen-strengthening layer addresses the underlying reason the dampness has accumulated in the middle jiao: a constitutionally insufficient or acutely overwhelmed spleen qi lacks the transforming function needed to metabolize the dampness from summer food, drink, and environmental humidity, and without spleen qi support, the formula's dampness-transforming herbs cannot prevent dampness from re-accumulating after the initial exterior-interior summerheat-dampness pattern is cleared.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eLung qi diffusion and upper burner direction through Jie Geng to ensure the formula's qi-regulating actions reach the full body axis from upper to lower burner:\u003c\/strong\u003e Diffuses the lung qi upward and outward through Jie Geng (platycodon root), the \"boat herb\" that floats the formula's qi-regulating and dampness-transforming action through the chest and upper burner, ensuring the qi-rectifying effects of the formula reach the full body axis from the upper burner (lung) through the middle burner (spleen and stomach) to the lower burner.

In veterinary practice, the summerheat-dampness pattern typically presents as acute digestive disruption (turbid dampness disturbing the spleen and stomach) combined with stomach qi ascending counterflow and mild exterior signs, most commonly seen in animals after exposure to summer heat, humidity, changes in diet, or excessive consumption of raw, cold, or difficult-to-digest food during hot weather. The TCVM treatment principle for summerheat-dampness is to simultaneously release the exterior pathogenic factor, transform the internal dampness, regulate the qi of the middle jiao, and harmonize the spleen and stomach, which is exactly the four-action strategy that Huo Xiang Zheng Qi San executes through its eleven herbs.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eSecondary action - the \"zheng qi\" (rectifying the qi) principle as the central therapeutic strategy distinguishing Huo Xiang Zheng Qi San from formulas that only release the exterior or only transform dampness:\u003c\/strong\u003e The formula's name reflects the classical TCVM principle of \"zheng qi\" (rectifying or correcting the qi) as the central strategy: rather than simply expelling the exterior pathogenic factor or draining the dampness, Huo Xiang Zheng Qi San corrects the disordered qi dynamic of the summerheat-dampness pattern by simultaneously releasing the exterior factor that blocks the defensive qi from functioning, transforming the internal dampness that obstructs the spleen and stomach qi, regulating the ascending and descending qi of the middle jiao (redirecting the ascending stomach qi counterflow and restoring the descending stomach and spleen qi), and strengthening the spleen's qi-transforming and dampness-metabolizing function to prevent re-accumulation. This comprehensive qi-rectifying strategy addresses the summerheat-dampness pattern as a whole qi dynamic disruption rather than targeting any single pathogenic factor in isolation, reflecting the classical TCVM formulation principle of treating the pattern rather than the symptom.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eAvailable Forms\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul style=\"text-align: left;\"\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003ePowder - Canine Blend (for dogs and cats):\u003c\/strong\u003e 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.

In TCVM, \"summerheat\" refers to the hot-season external pathogenic factor, and the summerheat-dampness pattern typically develops in animals exposed to summer heat and humidity, dietary changes involving excessive cold, raw, or difficult-to-digest food during hot weather, or environmental dampness combined with heat. The veterinarian confirms the summerheat-dampness pattern through tongue assessment (pale or slightly red tongue with a thick white or greasy coating reflecting the dampness), pulse character (soft or slippery pulse reflecting the dampness accumulation), and differentiation from patterns requiring other therapeutic formulas: spleen qi vacuity digestive disruption without the exterior component, damp-heat in the large intestine, or food stagnation patterns each require different formula approaches.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eHow is Huo Xiang Zheng Qi San administered to dogs, cats, and horses?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eMix 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. Because Huo Xiang Zheng Qi San is an aromatic dampness-transforming and exterior-releasing formula rather than a constitutional tonification formula, it is typically used for shorter treatment courses timed to the active summerheat-dampness presentation and discontinued once the pattern has resolved; your authorizing veterinarian will determine the appropriate treatment duration based on your animal's tongue, pulse, and clinical response.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eHow long does it take to see results with Huo Xiang Zheng Qi San?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eAs an exterior-releasing and dampness-transforming formula addressing an acute or subacute summerheat-dampness pattern, Huo Xiang Zheng Qi San typically produces results relatively quickly compared to constitutional tonification formulas. Improvement in stomach qi counterflow signs (nausea, vomiting, regurgitation) and digestive disruption is often seen within 3 to 7 days, as the formula's aromatic herbs clear middle jiao dampness and redirect ascending stomach qi. Full resolution of the summerheat-dampness pattern, including restoration of normal tongue coating and pulse character, typically requires 2 to 4 weeks of consistent use. Your authorizing veterinarian will monitor the tongue coating (the dampness indicator), pulse character, and digestive signs throughout the treatment course to confirm the pattern is resolving and determine when to discontinue the formula or transition to a constitutional spleen qi-strengthening formula if the underlying spleen qi vacuity requires longer-term support.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eWhat is \"summerheat\" in TCVM, and why is it relevant for pets?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eIn Traditional Chinese Veterinary Medicine, summerheat (shu) is the external pathogenic factor associated with late summer and the hot-humid season, characterized by heat and a tendency to combine with dampness to form the summerheat-dampness (shu shi) combined pattern. Unlike the other five external pathogenic factors (wind, cold, dampness, dryness, and fire), summerheat only occurs in the external form and is always associated with the hot season. In pets, the summerheat-dampness pattern develops when the hot, humid environment (summerheat) combines with internal dampness from dietary factors: excessive raw, cold, or rich food during summer, sudden dietary changes, or food that the individual animal's spleen qi cannot adequately transform given the concurrent heat burden. Outdoor animals, working animals, and animals with constitutionally weak spleen qi are particularly susceptible to the summerheat-dampness pattern during hot, humid weather. The pattern is distinguished from simple food stagnation by simultaneous exterior signs (mild chills alongside heat exposure and a slightly floating pulse component) and from damp-heat in the large intestine by prominent stomach qi counterflow and the combined exterior-interior nature of the presentation that Huo Xiang Zheng Qi San specifically addresses.\u003c\/span\u003e\u003c\/p\u003e","published_at":"2022-05-20T18:02:14-05:00","created_at":"2022-04-29T09:08:38-05:00","vendor":"Herbsmith Rx","type":"Pet Vitamins \u0026 Supplements","tags":["Herb_Type_Powder","Product_Type_Herb","Species_Cat","Species_Dog","Species_Horse","Vendor_Herbsmith_Rx"],"price":7000,"price_min":7000,"price_max":22200,"available":true,"price_varies":true,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":40021440888902,"title":"Powder -

Also known as Agastache Powder to Rectify the Qi or the Agastache Combination, this eleven-herb formula from the Song dynasty Imperial Grace Formulary (Tai Ping Hui Min He Ji Ju Fang, 1107 CE) addresses the summerheat-dampness pattern where external wind-cold or summerheat combines with internal dampness to disrupt the middle jiao, producing turbid dampness disturbing the spleen and stomach, stomach qi ascending counterflow, and the characteristic digestive and systemic signs of the summerheat-dampness pattern. The eponymous principal herb Huo Xiang (agastache, 15% of the formula) is the only classical herb that simultaneously releases the exterior pathogenic factor, transforms the internal middle jiao dampness, harmonizes the stomach, and redirects ascending stomach qi counterflow, making it uniquely suited as the lead herb for the combined exterior-interior summerheat-dampness presentation. The remaining ten herbs provide targeted exterior release (Zi Su Ye, Bai Zhi), middle jiao qi-regulating and dampness-transforming coverage (Hou Po, Chen Pi, Ban Xia, Da Fu Pi), spleen qi-strengthening and dampness-transforming support (Bai Zhu, Fu Ling), lung qi-diffusing direction (Jie Geng), and harmonization (Zhi Gan Cao). Well suited for dogs, cats, and horses presenting with the summerheat-dampness pattern, characterized by turbid dampness disturbing the middle jiao with loose stools or digestive upset from dampness accumulation, nausea and stomach qi ascending counterflow (expressed as vomiting or regurgitation in animals), abdominal distension and fullness from dampness obstructing the middle jiao qi, simultaneous exterior signs of mild chills, a pale or slightly red tongue with a thick white or greasy coating reflecting the dampness pattern, and a soft or slippery pulse.

In veterinary practice, the summerheat-dampness pattern typically presents as acute digestive disruption (turbid dampness disturbing the spleen and stomach) combined with stomach qi ascending counterflow and mild exterior signs, most commonly seen in animals after exposure to summer heat, humidity, changes in diet, or excessive consumption of raw, cold, or difficult-to-digest food during hot weather. The TCVM treatment principle for summerheat-dampness is to simultaneously release the exterior pathogenic factor, transform the internal dampness, regulate the qi of the middle jiao, and harmonize the spleen and stomach, which is exactly the four-action strategy that Huo Xiang Zheng Qi San executes through its eleven herbs.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003eSecondary action - the \"zheng qi\" (rectifying the qi) principle as the central therapeutic strategy distinguishing Huo Xiang Zheng Qi San from formulas that only release the exterior or only transform dampness:\u003c\/strong\u003e The formula's name reflects the classical TCVM principle of \"zheng qi\" (rectifying or correcting the qi) as the central strategy: rather than simply expelling the exterior pathogenic factor or draining the dampness, Huo Xiang Zheng Qi San corrects the disordered qi dynamic of the summerheat-dampness pattern by simultaneously releasing the exterior factor that blocks the defensive qi from functioning, transforming the internal dampness that obstructs the spleen and stomach qi, regulating the ascending and descending qi of the middle jiao (redirecting the ascending stomach qi counterflow and restoring the descending stomach and spleen qi), and strengthening the spleen's qi-transforming and dampness-metabolizing function to prevent re-accumulation.

In TCVM, \"summerheat\" refers to the hot-season external pathogenic factor, and the summerheat-dampness pattern typically develops in animals exposed to summer heat and humidity, dietary changes involving excessive cold, raw, or difficult-to-digest food during hot weather, or environmental dampness combined with heat. The veterinarian confirms the summerheat-dampness pattern through tongue assessment (pale or slightly red tongue with a thick white or greasy coating reflecting the dampness), pulse character (soft or slippery pulse reflecting the dampness accumulation), and differentiation from patterns requiring other therapeutic formulas: spleen qi vacuity digestive disruption without the exterior component, damp-heat in the large intestine, or food stagnation patterns each require different formula approaches.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eHow is Huo Xiang Zheng Qi San administered to dogs, cats, and horses?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eMix 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. Because Huo Xiang Zheng Qi San is an aromatic dampness-transforming and exterior-releasing formula rather than a constitutional tonification formula, it is typically used for shorter treatment courses timed to the active summerheat-dampness presentation and discontinued once the pattern has resolved; your authorizing veterinarian will determine the appropriate treatment duration based on your animal's tongue, pulse, and clinical response.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eHow long does it take to see results with Huo Xiang Zheng Qi San?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eAs an exterior-releasing and dampness-transforming formula addressing an acute or subacute summerheat-dampness pattern, Huo Xiang Zheng Qi San typically produces results relatively quickly compared to constitutional tonification formulas. Improvement in stomach qi counterflow signs (nausea, vomiting, regurgitation) and digestive disruption is often seen within 3 to 7 days, as the formula's aromatic herbs clear middle jiao dampness and redirect ascending stomach qi. Full resolution of the summerheat-dampness pattern, including restoration of normal tongue coating and pulse character, typically requires 2 to 4 weeks of consistent use. Your authorizing veterinarian will monitor the tongue coating (the dampness indicator), pulse character, and digestive signs throughout the treatment course to confirm the pattern is resolving and determine when to discontinue the formula or transition to a constitutional spleen qi-strengthening formula if the underlying spleen qi vacuity requires longer-term support.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eWhat is \"summerheat\" in TCVM, and why is it relevant for pets?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eIn Traditional Chinese Veterinary Medicine, summerheat (shu) is the external pathogenic factor associated with late summer and the hot-humid season, characterized by heat and a tendency to combine with dampness to form the summerheat-dampness (shu shi) combined pattern. Unlike the other five external pathogenic factors (wind, cold, dampness, dryness, and fire), summerheat only occurs in the external form and is always associated with the hot season. In pets, the summerheat-dampness pattern develops when the hot, humid environment (summerheat) combines with internal dampness from dietary factors: excessive raw, cold, or rich food during summer, sudden dietary changes, or food that the individual animal's spleen qi cannot adequately transform given the concurrent heat burden. Outdoor animals, working animals, and animals with constitutionally weak spleen qi are particularly susceptible to the summerheat-dampness pattern during hot, humid weather. The pattern is distinguished from simple food stagnation by simultaneous exterior signs (mild chills alongside heat exposure and a slightly floating pulse component) and from damp-heat in the large intestine by prominent stomach qi counterflow and the combined exterior-interior nature of the presentation that Huo Xiang Zheng Qi San specifically addresses.\u003c\/span\u003e\u003c\/p\u003e"}
