Kan Essentials Subdue Internal Wind is a classical Chinese herbal formula recommended by holistic veterinarians to transform phlegm, extinguish internal wind, dry and dispel damp in the middle burner, tonify spleen qi, direct rebellious qi downward, and clear heat in dogs and cats presenting with the pattern of spleen qi deficiency with upward disturbance of wind-phlegm and damp-phlegm accumulation. Also known by its classical name Ban Xia Bai Zhu Tian Ma Tang (Pinellia, White Atractylodes, and Gastrodia Decoction), the formula is named after its three principal herbs - Jiang Ban Xia (ginger-cured pinellia rhizome), Bai Zhu (white atractylodes rhizome), and Tian Ma (gastrodia rhizome) - whose combined actions address the phlegm-wind mechanism at its source. The formula's conceptual core is the TCVM understanding of how spleen qi deficiency generates the phlegm-wind pattern: when the spleen's transforming and transporting function is insufficient, it fails to process the body's fluids and nutrients normally, causing unprocessed damp to accumulate and condense gradually into phlegm; as phlegm accumulates in the channels and vessels, it obstructs the upward nourishment of the brain and sensory orifices; the accumulated phlegm eventually stirs internal wind as it ascends and disturbs the upper burner; and the resulting wind-phlegm disturbing upward produces the characteristic signs of the pattern - occasional loss of balance, tremors, muscle twitches, somnolence, occasional lethargy, and the neurological and vestibular signs that accompany phlegm-wind rising. The formula purges accumulated wind-phlegm through its chief herbs while also addressing the underlying spleen qi deficiency that roots the phlegm-generating process, treating the pattern at both the branch (wind-phlegm disturbing upward) and the root (spleen qi deficiency allowing phlegm to accumulate). The Kan Essentials version strengthens the classical formula's secondary functions by adding herbs to drain damp through the bladder (Ze Xie), clear the accumulated heat (Huang Qin and Huang Bai), support normal stomach function and prevent food stasis (Chao Mai Ya and Shen Qu), and strongly tonify qi (Hong Ren Shen). This formula is contraindicated in animals with vertigo from ascendant liver yang or blood deficiency, as those patterns require fundamentally different treatment strategies. Available as a liquid extract and tablet. Dosing varies by species and body weight, and your authorizing veterinarian will provide specific guidance.

What It Supports
- Phlegm-wind transformation and internal wind extinguishing through the classical Tian Ma and Jiang Ban Xia chief herb pairing - addressing the branch (wind phlegm disturbing upward) and the root (phlegm accumulation generating wind) simultaneously: Transforms the phlegm accumulation that is generating the internal wind through Jiang Ban Xia, extinguishes the internal wind that the phlegm-wind ascent has stirred through Tian Ma, and addresses the full phlegm-wind mechanism through the classic paired combination of these two herbs that gives the formula its name and defines its primary clinical strategy. Jiang Ban Xia (ginger-cured pinellia rhizome, Pinellia ternata) is the phlegm-transforming component of the classical chief pair; its acrid and warm ginger-cured nature enters the spleen, stomach, and lung channels to transform phlegm-damp, dry dampness in the middle jiao that feeds phlegm accumulation, descend the rebellious stomach qi that phlegm obstruction drives upward, and harmonize the stomach - addressing the phlegm root of the wind-phlegm pattern. Tian Ma (gastrodia rhizome, Gastrodia elata) is the wind-extinguishing component of the classical chief pair; its neutral and slightly sweet nature enters the liver channel to extinguish internal wind, calm liver wind, address the tremors, muscle twitches, and loss of balance that wind-phlegm disturbance upward produces, and suppress the upward disturbance that phlegm-wind has created in the channels and sensory orifices. Together, Jiang Ban Xia's phlegm-transforming action (addressing the source of the wind) and Tian Ma's wind-extinguishing action (addressing the manifestation of the phlegm) constitute the classical two-pronged strategy of Ban Xia Bai Zhu Tian Ma Tang and are the reason this formula is the primary TCVM formula for the phlegm-wind disturbing upward pattern. Tian Ma gastrodin content; monitoring warranted with anticonvulsant medications (potential additive CNS effects) and sedative medications. Jiang Ban Xia is generally well tolerated in ginger-cured form; caution in pregnant animals.
- Spleen qi tonifying and middle burner damp drying to address the root cause of phlegm production through Bai Zhu, Fu Ling, Hong Ren Shen, and Gan Cao - the formula's four spleen-supporting herbs: Tonifies spleen qi to restore the transforming and transporting function whose deficiency is the root cause of the damp accumulation and phlegm production driving the wind-phlegm pattern; dries the accumulated damp in the middle burner that the deficient spleen has allowed to collect; strengthens the spleen's ability to process fluids normally so phlegm generation is reduced at its source; and provides the qi foundation needed for the wind-extinguishing and phlegm-transforming strategy to operate from a position of strength rather than depletion. In TCVM, the spleen's transforming and transporting function is the primary mechanism by which the body processes the fluids and nutrients it ingests; when spleen qi is deficient, this processing fails, unprocessed damp accumulates, the accumulated damp condenses into phlegm, and phlegm becomes the substrate for the wind-phlegm pattern. Strengthening spleen qi therefore addresses the pattern at its generating source - reducing new phlegm production while the formula's phlegm-transforming and wind-extinguishing herbs clear the accumulated phlegm-wind that has already developed. Bai Zhu (white atractylodes rhizome, Atractylodes macrocephala) is the formula's second namesake herb and primary spleen tonic; its bitter and warm nature enters the spleen and stomach channels to tonify spleen qi, dry damp in the middle burner, and directly strengthen the spleen's transforming and transporting function. Fu Ling (poria, Poria cocos) supports spleen function and resolves dampness through its bland and sweet leaching action, reducing the damp substrate from which phlegm forms while strengthening the spleen's fluid-metabolizing capacity. Hong Ren Shen (Chinese red ginseng root and rhizome, Panax ginseng, red-processed) strongly tonifies yuan qi and spleen qi to address the underlying deficiency driving the damp and phlegm accumulation; its deep qi-tonifying action provides the constitutional foundation that enables the spleen to resume normal function. Gan Cao (Chinese licorice root and rhizome, Glycyrrhiza uralensis) gently tonifies spleen qi, harmonizes the formula's diverse warm damp-drying and cool heat-clearing herbs, and moderates the actions of the more acrid and drying herbs in the formula. Hong Ren Shen ginsenoside content; monitoring warranted with MAOIs (CNS stimulation), insulin and oral hypoglycemic agents (additive hypoglycemia), and stimulant medications. Gan Cao glycyrrhizin; monitoring warranted with corticosteroids and antihypertensive medications.
- Middle burner damp drying and dispelling to reduce phlegm substrate through Bai Zhu, Cang Zhu, and Chen Pi, with rebellious qi directing downward through Jiang Ban Xia and Chen Pi: Dries and dispels the accumulated damp in the middle burner that spleen qi deficiency has allowed to collect; prevents the damp-to-phlegm condensation process that feeds the phlegm-wind pattern; moves the qi stagnating from phlegm accumulation in the middle jiao; and directs rebellious stomach qi downward to resolve the occasional vomiting and nausea that phlegm obstruction drives upward through the combined middle-burner drying and qi-descending action of these three herbs. Bai Zhu's damp-drying action at the spleen-stomach level addresses the primary source of damp accumulation in the middle burner. Cang Zhu (cang-zhu atractylodes rhizome, Atractylodes lancea) provides a stronger, more penetrating damp-drying and damp-dispelling action than Bai Zhu through its more acrid, drying nature; where Bai Zhu tonifies the spleen while drying damp, Cang Zhu more aggressively dispels and dries accumulated damp through its strongly aromatic, volatile-oil-driven drying action. Chen Pi (tangerine dried rind of mature fruit, Citrus reticulata) moves qi stagnating from phlegm accumulation in the middle jiao, assists Jiang Ban Xia in restoring the normal descending qi movement of the stomach that phlegm obstruction has disrupted, dries dampness contributing to phlegm formation, and transforms phlegm through its qi-moving action - addressing the phlegm-qi stagnation cycle that perpetuates accumulation. Generally well tolerated.
- Damp draining through the bladder and heat clearing through Ze Xie, Huang Qin, and Huang Bai - the three Kan Essentials augmentation herbs addressing secondary damp drainage, heat accumulation, and the heat intolerance signs of the pattern: Drains the accumulated damp downward and out through the urinary route via Ze Xie, clears the heat that has accumulated with the damp-phlegm through Huang Qin and Huang Bai, and addresses the heat intolerance and heat-in-joints-and-skin signs that accompany the phlegm-wind pattern when damp-heat is also present. Ze Xie (Asian water plantain rhizome, Alisma plantago-aquatica) drains damp through the bladder channel, promoting urination to guide accumulated damp out of the body through the urinary route rather than letting it condense into phlegm or accumulate in the middle burner. Huang Qin (Chinese skullcap root, Scutellaria baicalensis) clears heat from the upper and middle burner, drains fire, and specifically addresses the heat that accumulates with phlegm in the lung and middle-burner channels; its bitter and cold nature enters the lung, heart, liver, and large intestine channels to clear phlegm-associated heat and the general heat intolerance that accompanies the pattern. Huang Bai (Phellodendron bark, Phellodendron amurense) clears damp heat from the lower burner and kidney-bladder channel through its bitter and cold nature; complementing Huang Qin's upper-middle burner heat clearing with a lower-burner focus, Huang Bai addresses the accumulated damp heat that Ze Xie's urinary-draining action directs toward the bladder. Huang Qin baicalin content; monitoring warranted with CYP450-metabolized medications and warfarin (anticoagulant effect modification). Huang Bai berberine content; monitoring warranted with insulin and oral hypoglycemic agents (additive hypoglycemia), warfarin, and CYP3A4-metabolized medications.
- Normal stomach function supporting and food stasis preventing through Chao Mai Ya and Shen Qu - protecting the digestive system from the formula's damp-drying herbs: Supports normal stomach function, promotes the digestion and movement of food through the middle jiao, and prevents food stasis that the formula's damp-drying and phlegm-transforming herbs might promote if food is not moved adequately through the stomach. In TCVM, the digestive herbs Chao Mai Ya and Shen Qu serve as protective adjuncts in formulas with strong damp-drying content; by ensuring food moves through the stomach normally, they prevent the additional stasis and accumulation that undigested food creates in an already phlegm-accumulating middle jiao. Chao Mai Ya (dry-fried barley sprout, Hordeum vulgare) supports normal stomach function, promotes food movement and digestion, and gently supports spleen function through dry-frying, which concentrates its digestive-promoting properties. Shen Qu (medicated leaven) is a fermented digestive adjunct that promotes digestion, prevents food stasis, and supports normal stomach and spleen function through its fermentation-derived digestive enzymes. Both generally well tolerated.
TCVM Principles
- Primary action - spleen qi deficiency with upward disturbance of wind phlegm and damp-phlegm accumulation, through the root-branch combined strategy of phlegm-wind branch treatment (Tian Ma wind extinguishing, Jiang Ban Xia phlegm transforming) and spleen qi deficiency root treatment (Bai Zhu, Fu Ling, Hong Ren Shen, Gan Cao spleen tonifying), with middle-burner damp drying (Bai Zhu, Cang Zhu, Chen Pi), lower-burner damp draining (Ze Xie), heat clearing (Huang Qin, Huang Bai), and digestive protection (Chao Mai Ya, Shen Qu): Subdue Internal Wind addresses the phlegm-wind disturbing upward pattern through the root-branch strategy that the classical Ban Xia Bai Zhu Tian Ma Tang architecture is designed to implement. The branch treatment (Tian Ma and Jiang Ban Xia) extinguishes the wind and transforms the phlegm that actively disturbs the upper burner, producing neurological and vestibular signs. The root treatment (Bai Zhu, Fu Ling, Hong Ren Shen, Gan Cao) tonifies the spleen qi, whose deficiency generates new phlegm through the damp-to-phlegm condensation pathway. The Kan Essentials augmentations (Ze Xie, Huang Qin, Huang Bai, Chao Mai Ya, Shen Qu, Hong Ren Shen) strengthen the formula's secondary damp-draining, heat-clearing, and digestive-protecting functions. Treatment Principles: transform phlegm, extinguish internal wind, tonify spleen qi, dry and dispel damp in the middle burner, direct rebellious qi downward, drain damp through the bladder, and clear heat associated with the damp-phlegm accumulation.
- Critical contraindication: not appropriate for vertigo or neurological signs from ascendant liver yang or blood deficiency - these require fundamentally different formulas; the phlegm-wind pattern is confirmed by greasy tongue coating, slippery pulse, round abdomen, oily coat, elevated appetite, and somnolence reflecting phlegm accumulation rather than the yin deficiency or blood deficiency signs of ascendant liver yang or empty wind: Subdue Internal Wind is appropriate only for the phlegm-wind disturbing upward pattern where the vertigo, loss of balance, tremors, and neurological signs arise from phlegm accumulation stirring internal wind - not from ascendant liver yang (where yin deficiency drives yang to rise, confirmed by red tongue without coating and wiry-rapid pulse) or from blood deficiency wind (where empty wind arises from blood failing to nourish the sinews, confirmed by pale tongue and thin-weak pulse). Using this phlegm-transforming and damp-drying formula in an ascendant liver yang or blood-deficiency pattern would further deplete yin or blood through the formula's warm, drying action, potentially worsening the condition. The pattern confirmation signs for appropriate use are: greasy tongue coating (reflecting damp-phlegm accumulation), slippery and possibly rapid pulse (reflecting phlegm and possible heat), round abdomen (damp-phlegm accumulation in the middle jiao), oily coat (damp accumulation in the surface), elevated thirst and appetite (spleen deficiency pattern), somnolence and lethargy (phlegm clouding the sensory orifices), and occasional mucoid discharges (phlegm expressed through the body's orifices). Your authorizing veterinarian must confirm the phlegm-wind pattern through complete clinical and TCVM assessment before initiating this formula.

Active Ingredient TCVM Actions
Subdue Internal Wind (Ban Xia Bai Zhu Tian Ma Tang) is named for its three principal herbs - Jiang Ban Xia (phlegm transforming), Bai Zhu (spleen tonifying and damp drying), and Tian Ma (wind extinguishing) - whose combined actions address the phlegm-wind disturbing upward pattern at both branch (wind phlegm) and root (spleen qi deficiency). The Kan Essentials version adds five herbs to strengthen damp draining, heat clearing, and digestive protection:
- Tian Ma (Gastrodia elata) - Gastrodia Rhizome / Heavenly Hemp: Chief wind-extinguishing herb and formula namesake; extinguishes internal wind, calms liver wind, addresses tremors, muscle twitches, and loss of balance from phlegm-wind disturbing upward. Gastrodin content; monitoring warranted with anticonvulsant and sedative medications (potential additive CNS effects).
- Bai Zhu (Atractylodes macrocephala) - White Atractylodes Rhizome: Formula namesake and primary spleen tonic; tonifies spleen qi, dries damp in the middle burner, and addresses the spleen deficiency root that generates phlegm. Generally well tolerated.
- Jiang Ban Xia (Pinellia ternata, ginger-cured) - Ginger-Cured Pinellia Rhizome: Formula namesake and primary phlegm transformer; transforms phlegm-damp, dries middle-jiao dampness, descends rebellious stomach qi, and harmonizes the stomach. Generally well tolerated in ginger-cured form; caution in pregnant animals.
- Fu Ling (Poria cocos) - Poria / Hoelen: Supports spleen function, resolves dampness through bland leaching action, and reduces the damp substrate from which phlegm forms. Generally well tolerated.
- Chen Pi (Citrus reticulata) - Tangerine Dried Rind of Mature Fruit / Tangerine Peel: Moves qi stagnating from phlegm accumulation, assists Jiang Ban Xia in restoring normal stomach qi descent, dries damp, and transforms phlegm through qi-moving action. Generally well tolerated.
- Bai Zhu (see above) and Cang Zhu (Atractylodes lancea) - Cang-Zhu Atractylodes Rhizome / Gray Atractylodes: Kan Essentials addition; more aggressively dispels and dries accumulated damp in the middle burner than Bai Zhu through its more acrid volatile-oil-driven drying action, complementing Bai Zhu's spleen-tonifying damp-drying with a stronger damp-dispelling contribution. Generally well tolerated.
- Hong Ren Shen (Panax ginseng, red-processed) - Chinese Red Ginseng Root and Rhizome: Kan Essentials addition; strongly tonifies yuan qi and spleen qi to address the deep constitutional deficiency driving damp and phlegm accumulation. Ginsenoside content; monitoring warranted with MAOIs, insulin and oral hypoglycemic agents (additive hypoglycemia), and stimulant medications.
- Ze Xie (Alisma plantago-aquatica) - Asian Water Plantain Rhizome: Kan Essentials addition; drains accumulated damp via the bladder, promoting urination to guide damp out of the body rather than allowing continued phlegm condensation. Generally well tolerated.
- Huang Qin (Scutellaria baicalensis) - Chinese Skullcap Root / Baical Skullcap: Kan Essentials addition; clears heat from the upper and middle burner, drains fire, and addresses heat accumulating with phlegm in the lung and middle-burner channels. Baicalin content; monitoring warranted with CYP450-metabolized medications and warfarin.

Berberine content; monitoring warranted with insulin and oral hypoglycemic agents (additive hypoglycemia), warfarin, and CYP3A4-metabolized medications.
- Chao Mai Ya (Hordeum vulgare, dry-fried) - Dry-Fried Barley Sprout / Malt: Kan Essentials addition; supports normal stomach function and promotes food movement to prevent food stasis from the formula's damp-drying herbs. Generally well tolerated.
- Shen Qu - Medicated Leaven: Kan Essentials addition; fermented digestive adjunct that promotes digestion and prevents food stasis in the middle jiao. Generally well tolerated.
- Gan Cao (Glycyrrhiza uralensis) - Chinese Licorice Root and Rhizome: Gently tonifies spleen qi, harmonizes the formula's warm drying and cold heat-clearing herbs. Glycyrrhizin content; monitoring warranted with corticosteroids and antihypertensive medications.
Potential Drug Interactions
Subdue Internal Wind's primary drug interaction concern centers on Tian Ma and the formula's two anticonvulsant-adjacent herbs. Tian Ma (gastrodia) has documented CNS-modulating and anticonvulsant-adjacent effects through its gastrodin content; animals on phenobarbital, potassium bromide, levetiracetam, or other anticonvulsant medications warrant veterinary review before initiating this formula, as additive or interactive CNS effects are possible and anticonvulsant dosing may need monitoring. Sedative medications warrant similar monitoring given Tian Ma's CNS activity. Hong Ren Shen's ginsenoside content requires monitoring in animals on MAOIs (CNS stimulation risk) and insulin or oral hypoglycemic agents (additive hypoglycemia). Huang Bai's berberine content has well-documented interactions with insulin and oral hypoglycemic agents (additive hypoglycemia), warfarin (INR modification), and CYP3A4-metabolized medications with narrow therapeutic windows; animals on these medications warrant specific veterinary review. Huang Qin's baicalin content also interacts with warfarin and CYP450-metabolized medications. Gan Cao's glycyrrhizin warrants monitoring in animals on corticosteroids and antihypertensive medications. Jiang Ban Xia warrants caution in pregnant animals.
Medication categories warranting extra caution: anticonvulsant medications (Tian Ma CNS-modulating effects - primary concern), sedative medications (Tian Ma), MAOIs and insulin or oral hypoglycemic agents (Hong Ren Shen and Huang Bai additive hypoglycemia), warfarin (Huang Qin baicalin and Huang Bai berberine), CYP3A4-metabolized medications with narrow therapeutic windows (Huang Bai berberine and Huang Qin baicalin), and corticosteroids and antihypertensives (Gan Cao). Your authorizing veterinarian will determine appropriateness based on your pet's pattern assessment, current medications, and anticonvulsant blood levels, tongue quality, and pulse character.

Frequently Asked Questions
What is Subdue Internal Wind, and what phlegm-wind disturbing upward pattern does it address?
Subdue Internal Wind (Ban Xia Bai Zhu Tian Ma Tang, named for its three principal herbs Jiang Ban Xia, Bai Zhu, and Tian Ma) is a classical Chinese herbal formula addressing the phlegm-wind disturbing upward pattern - the specific TCVM mechanism in which spleen qi deficiency drives damp accumulation, damp condenses into phlegm, phlegm accumulates in the channels and vessels, and the accumulated phlegm eventually stirs and carries internal wind upward to disturb the brain, sensory orifices, and vestibular function. The resulting pattern is characterized by occasional loss of balance, tremors, muscle twitches, somnolence, and neurological signs, alongside phlegm-accumulation signs such as a round abdomen, oily or greasy coat, occasional mucoid discharges, elevated thirst and appetite, and a greasy tongue coating with a slippery pulse. Because the formula is designed for the specific phlegm-wind pattern with spleen qi deficiency at its root, it is contraindicated in animals whose neurological signs arise from ascendant liver yang (yin deficiency driving yang to rise - different tongue, pulse, and constitutional signs) or from blood deficiency wind (empty wind from blood failing to nourish the sinews - also different pattern signs). Your authorizing veterinarian will differentiate between these patterns through complete tongue, pulse, and clinical assessment before recommending this formula.
How is Subdue Internal Wind administered, and what animals with seizures or neurological signs is it appropriate for?
Subdue Internal Wind is available in concentrated liquid extract (1 oz, 4 oz, or 8 oz) and 500 mg tablets (60, 120, or 300 count). You can mix the liquid directly into food or administer it with a dropper; you can give the tablets directly or hide them in food or a soft treat for easy administration. Dosing varies by species and body weight, and your authorizing veterinarian will provide specific dosing guidance. For animals already on anticonvulsant medications (phenobarbital, potassium bromide, levetiracetam), the formula's Tian Ma (gastrodia) content warrants discussion with the authorizing veterinarian before initiating, as Tian Ma has CNS-modulating effects that may interact with anticonvulsant activity and monitoring of anticonvulsant blood levels may be appropriate during the initial period of combined use. Animals on insulin or oral hypoglycemic agents require monitoring for additive hypoglycemia from both Hong Ren Shen and Huang Bai. This formula is contraindicated in pregnant animals (Jiang Ban Xia caution).
How long does it take to see results with Subdue Internal Wind, and does the formula address the root or only the symptoms?
Subdue Internal Wind is specifically designed as a root-and-branch formula - treating both the phlegm-wind symptoms (branch) and the underlying spleen qi deficiency generating phlegm (root) simultaneously. For the branch neurological signs - tremors, loss of balance, muscle twitches, and somnolence - some improvement may be seen within 2 to 4 weeks of consistent use as the phlegm-transforming and wind-extinguishing herbs begin to clear the wind-phlegm from the channels and upper burner. For the root spleen qi deficiency - the ongoing phlegm-generating process that keeps producing new phlegm to replace what the formula is clearing - meaningful improvement requires longer sustained use as the spleen-tonifying herbs gradually rebuild the spleen's transforming and transporting capacity. This is why Subdue Internal Wind contains both the fast-acting phlegm-transforming and wind-extinguishing herbs (Tian Ma and Jiang Ban Xia) and the slower-acting spleen tonics (Bai Zhu, Fu Ling, Hong Ren Shen); the branch treatment provides the relatively prompt symptom improvement while the root treatment builds the constitutional correction that prevents the pattern from regenerating. Animals with more advanced or long-standing phlegm-wind patterns may require 8 to 12 weeks or more before significant neurological improvement is evident. Your authorizing veterinarian will monitor tongue coating quality (reduced greasiness), pulse character (reduced slipperiness), and clinical neurological signs to assess treatment progress.
What signs distinguish the phlegm-wind pattern that needs Subdue Internal Wind from the ascendant liver yang or blood deficiency patterns that contraindicate it?
The three patterns that can produce similar neurological signs in dogs and cats - phlegm-wind disturbing upward, ascendant liver yang, and blood deficiency wind - require completely different treatment strategies, and the wrong formula can worsen the pattern. The phlegm-wind pattern (appropriate for Subdue Internal Wind) is confirmed by its phlegm accumulation signs: greasy tongue coating, slippery pulse, round or distended abdomen, oily or greasy coat, elevated thirst and appetite, somnolence and lethargy, and occasional mucoid discharges - all reflecting phlegm accumulation throughout the body alongside the neurological signs. Ascendant liver yang (contraindicated for Subdue Internal Wind, which would aggravate it) presents with the yin deficiency signs driving yang upward: a red tongue typically without greasy coating, a wiry and possibly rapid pulse, heat signs, restlessness, and the constitutional yin-deficient picture of a lean, heat-intolerant animal; this pattern requires a yin-nourishing and yang-anchoring formula rather than a phlegm-drying formula. Blood deficiency wind (also contraindicated) presents with the blood deficiency signs of a pale tongue, thin and weak pulse, muscle wasting, dry coat, and the general blood-deficient constitution of a lean, low-energy animal without the phlegm signs; this pattern requires a blood-nourishing formula. Your authorizing veterinarian must complete a full tongue, pulse, and physical examination assessment to confirm which of these three patterns is present before selecting the appropriate formula, as the treatment strategies are not interchangeable.
