Sustenance Herbs KC Respiratory | Organic Herbal Lung & Respiratory Support

Sustenance Herbs KC Respiratory Formula for Dogs A six-herb certified organic tincture to support your dog's airway through kennel cough recovery and chronic respiratory situations, used alongside your vet's care. Six Organic or Wildcrafted Herbs NASC Quality Seal Veterinarian Formulated 2 fl oz Glass Tincture Why Holistic Households Reach For This Six certified organic herbs that support your dog's airway through kennel cough, bronchitis, and respiratory recovery. You know the sound. Your terrier came home from boarding three days ago and started that dry, honking cough that travels through the whole house. Or your senior dog's chronic bronchitis is flaring again with the cold autumn air. Or your dog is recovering from anesthesia and her breathing is working harder than usual. Or another dog in your multi-dog household just came down with kennel cough and you want to support everyone through the next few weeks. Each of these is what this respiratory tincture was built for. KC Respiratory Formula is the herbal tincture that holistic vets reach for during respiratory events like these. Six organic and wildcrafted herbs work together to support your dog's airway alongside the supportive care your vet has set up. You give the drops twice daily for two to three weeks during the acute recovery window. The herbs do their work while rest, hydration, and any prescription support your vet has recommended keep doing theirs. Most pet parents notice their dog's cough pattern eases over the first week and her energy steadies as the recovery window continues. The brand is small-batch and built by veterinarians for use in holistic veterinary practices. The six herbs in this formula are mullein, elecampane, coltsfoot, yarrow, mallow leaf, and goldenseal leaf. These are the foundational Western respiratory herbs, used for centuries before this formula brought them together. Every herb is certified organic or ethically wildcrafted. The whole product carries the NASC Quality Seal, an independent check on the label and the manufacturing. What this is: a natural herbal tincture to support your dog's airway during respiratory events, used alongside your vet's care. What this is not: a treatment for kennel cough or any respiratory infection, a substitute for prescription antibiotics or cough suppressants, or a cure for any condition. If your dog is coughing, your vet is the right first call. This tincture is the herbal layer that joins the supportive care plan, not the one that replaces it. A longer-than-usual safety section before you keep reading, because this formula has more contraindications than any other Sustenance Herbs tincture. The product is not safe for pregnant or nursing dogs. It is not safe for dogs with hypertension, gall bladder disease, seizure history, or paralysis. It cannot be used long-term continuously and needs to be used in pulse cycles. The goldenseal leaf in the formula has the same drug interaction profile as goldenseal root, which means dogs on prescription medication need their vet on board before starting. And the coltsfoot in the formula contains pyrrolizidine alkaloids, which is the reason for the strict pulse protocol approach. All of these are explained in plain English in the cautions box further down the page. Read every flag before deciding if this is the right fit for your dog. Cough suppressants quiet the symptom. These herbs help the airway clear. How Herbal Respiratory Support Works Two kinds of herbal action, working together: soothing the airway and helping it clear. A cough is the body's natural way of clearing the airway. Herbal respiratory support works on two sides of that natural process. The soothing (demulcent) herbs coat irritated mucous membranes so the dry hacking cough quiets down. The clearing (expectorant) herbs help the body move mucus and irritants up and out, so the deeper cough actually accomplishes its purpose. Most herbal respiratory products use one approach or the other. This formula uses both at once. Mullein and mallow leaf are the soothing layer. Their natural mucilage coats the irritated tissue of the upper airway. The hacking cough eases. The irritation calms. Your dog has space to actually recover instead of just enduring the irritation. Mullein has been the foundational Western lung herb for centuries, and mallow leaf adds a second reinforcing layer of the same soothing work. Elecampane and coltsfoot are the clearing layer. Both work in the deeper airway to support the natural ciliary action (the tiny hair-like cells that move mucus and irritants up and out of the lung). Yarrow adds anti-inflammatory and gentle circulation support. Goldenseal leaf brings a natural antimicrobial layer. This is different from a cough suppressant. Pharmaceutical cough syrups quiet the cough reflex so the symptom goes away. That can feel like relief in the short term, but it makes it harder for the body to actually clear the airway. Herbal respiratory blends like this one support both sides of the natural clearance process. The cough eases because the airway is being cleared, not because the cough has been silenced. When To Reach For This Six situations this tincture was built for. Kennel Cough Recovery Your dog has been diagnosed with kennel cough and your vet has cleared supportive home care. The two to three week pulse covers the standard recovery window. Chronic Bronchitis Flares Seasonal flares in dogs your vet is managing for chronic bronchitis. Used in pulse cycles during the flare windows, with your vet calibrating the rhythm. Collapsing Trachea Management Small-breed dogs whose collapsing trachea your vet is managing. A holistic herbal layer can ease the cough cycles that come with the condition, under vet supervision. Post-Anesthesia Recovery Your dog's lungs are working harder than usual after a recent surgery. Your vet has cleared a holistic herbal layer to support the natural recovery of the airway. Multi-Dog Households One dog in the house just came home with kennel cough. You want to support the other dogs through the exposure window with your vet's guidance. Sustenance Herbs Cabinet Expansion You already use Bor-L-Immune, AntiBact, Pet Calming Formula, or Kidney Works. KC Respiratory Formula is the fifth Sustenance Herbs product in the brand line. What Is In The Bottle Six herbs, each with a clear role in respiratory support. Featured Herb Mullein Mullein is the foundational Western lung herb. Indigenous nations across North America used it for centuries. European herbalists adopted it. Modern herbalists still reach for it first when the respiratory system needs support. The leaf is rich in mucilage (a natural gel-like substance) and other compounds that soothe irritated mucous membranes throughout the airway. Think of mullein as the soothing-and-clearing herb in one. The mucilage coats irritated tissue and eases the dry hacking cough that comes with respiratory inflammation. At the same time, the natural saponins (plant compounds) gently support the clearing of mucus from the lower airway. This dual action is why mullein leads almost every traditional Western respiratory formula, and why it is the lead ingredient in this Sustenance Herbs blend. Honest cautions. Mullein is one of the best-tolerated respiratory herbs in the Western tradition. Dogs with confirmed sensitivities to plants in the figwort family may rarely react. Most dogs do well with it. Featured Herb Coltsfoot Coltsfoot is the traditional cough-soothing herb whose Latin name (Tussilago) literally means "cough dispeller." European and Indigenous North American herbal traditions have used the leaves and flowers for centuries. The leaf contains mucilage, flavonoids, and one constituent that needs careful explanation: pyrrolizidine alkaloids, often shortened to PAs. Here is what PAs mean for your dog. These are plant compounds that can stress the liver in high doses over long periods of time. The leaf used in this formula has substantially lower PA content than the root of the same plant. The formulator uses the herb in proportional amounts within a six-herb blend. And the manufacturer's "not for long-term continuous use" guidance is designed to address this concern directly. The traditional reasoning for keeping coltsfoot in respiratory formulas is that its cough-soothing value has been documented for centuries. The careful pulse protocol approach makes the historical concern manageable. Honest cautions. Use only in pulse cycles, not indefinitely. Pair with milk thistle for liver support during any protocol longer than the standard acute pulse. If you are uncomfortable with the PA disclosure, choose a coltsfoot-free respiratory blend under your vet's guidance instead. Elecampane Elecampane is the deeper-airway expectorant herb that traditional European herbalists used for what the old texts called "damp lung" patterns. These are the wet, productive coughs where the body needs help moving mucus out of the lower airway. The active compounds support the natural ciliary clearance in the bronchi (the small breathing tubes that branch through the lung). Elecampane also has documented activity against several respiratory pathogens, which is part of why it earns its place in a kennel-cough-supportive blend. Honest cautions. Elecampane is in the same plant family as ragweed (the Asteraceae family), so dogs with confirmed ragweed allergies may rarely react. The herb stimulates bile flow, which is part of the reason this formula is not safe for dogs with gall bladder disease. It can also mildly affect blood pressure, which contributes to the hypertension caution. Yarrow Yarrow is the European and Indigenous North American herbal plant named for Achilles, the warrior who reportedly used it on the battlefield. Traditional Western respiratory formulas have used yarrow for centuries because of its anti-inflammatory and gentle circulation-supporting effects. The herb supports the body's natural inflammatory resolution in lung tissue and the small blood vessels that supply the airway. Honest cautions. Yarrow can mildly raise blood pressure, which is one reason this formula is not for dogs with hypertension. It contains trace amounts of a compound called thujone that can theoretically lower the seizure threshold, which is the reason for the seizure history caution. Yarrow has also been used historically to stimulate the uterus, so it is not safe for pregnant dogs. Mallow Leaf Mallow leaf is the gentle reinforcing demulcent that European herbal traditions paired with mullein for centuries. The leaf is rich in mucilage that coats irritated mucous membranes and adds a second soothing layer to mullein's primary work. Where mullein leads the soothing action, mallow leaf broadens the coverage across the upper airway. Honest cautions. Mallow leaf is one of the gentlest herbs in the Western herbal tradition. It is broadly well-tolerated and does not contribute to any of the major caution flags on this formula's label. Goldenseal Leaf Goldenseal leaf is the iconic North American antimicrobial herb that Cherokee, Iroquois, and other Indigenous nations used for generations. Modern Western herbalists adopted it as one of the foundational antimicrobial plants in their materia medica. The leaf carries the same berberine and hydrastine compounds that make the root such a strong natural antimicrobial. The leaf form has somewhat lower concentrations than the root. That makes the leaf a gentler choice for blended respiratory formulas. Wild goldenseal has been overharvested for over a century. The plant is now on an international conservation list. Responsible brands grow goldenseal on farms instead of taking it from the wild. Sustenance Herbs sources its goldenseal leaf from certified organic farms. Honest cautions. Goldenseal slows down liver enzymes that break down many prescription medications. The manufacturer explicitly calls out this "P450 drug interaction" concern on the label. If your dog is on any prescription, your vet needs to know before you start. Goldenseal is also not safe for pregnant or nursing dogs and for dogs with gall bladder disease. What This Looks Like For Your Dog Inside the two to three week recovery pulse. Picture your terrier who came home from boarding three days ago and started the dry honking cough that travels through the whole house. Your vet has examined her, diagnosed kennel cough, and cleared supportive home care. She is on rest and hydration. The household routine has shifted to give her quiet recovery space. Your vet recommends adding a herbal respiratory layer for the next two to three weeks. You give her the drops twice daily, either in her food or right in her mouth. Here is what tends to happen across the recovery window when six respiratory herbs are working alongside the body's own clearing process. The first few days: the cough starts to ease Mullein and mallow leaf coat the irritated mucous membranes of the upper airway. The dry hacking pattern softens. Your dog has space to actually rest between cough episodes instead of pacing through them. Elecampane and coltsfoot work in the deeper airway The clearing layer supports the natural ciliary action in the bronchi and bronchioles. Mucus and irritants move up and out rather than sitting in the lower lung. Yarrow supports the natural inflammatory resolution The lung tissue's natural inflammatory response gets steady support, and gentle circulation through the small blood vessels keeps doing its work. Goldenseal leaf adds the antimicrobial layer The natural antimicrobial action supports the body's own immune response to the respiratory bug. The gentler leaf form complements the rest of the blend rather than overpowering it. Week two: the breathing pattern steadies Most pet parents notice their dog's cough frequency drops. Her energy returns in small increments. She starts approaching food and water with her usual interest again. Week three: most acute events resolve The standard two to three week pulse covers the natural arc of most uncomplicated kennel cough recoveries. Your vet's recheck confirms she is ready to come off the protocol. The body did the recovering. The herbs supported the work. Pet parents often describe the difference as their dog seeming to move through the recovery rather than just enduring it. The cough was eased, the airway was supported, and the body had space to do its own healing work. The Quality Standard Organic, NASC-checked, vet-formulated, conservation-conscious. Six Organic or Wildcrafted Herbs Five of the six herbs are certified organic. Yarrow is responsibly wildcrafted from sustainable sources the brand has worked with for years. NASC Quality Seal An independent group, the National Animal Supplement Council, checks the label, the manufacturing, and the ingredients against industry quality standards. Western Respiratory Heritage Six herbs that traditional Western herbalism has used for respiratory function for centuries, with mullein as the lead lung herb in nearly every traditional formula. Conservation-Conscious Sourcing The goldenseal is sourced from certified organic farms, in respect of the plant's protected status under international conservation rules. Vet-Formulated Sustenance Herbs builds its formulas with veterinarians, for veterinarians. The product is used in holistic and integrative practices across the country. Amber Glass Bottle Light-protective amber glass with a glass dropper. No plastic touches the tincture, which protects the herbal compounds over time. Why Label-Reading Households Trust This Formula The Western respiratory canon, vet-formulated, with industry-leading contraindication transparency. Most respiratory pet products on the market do not tell you that coltsfoot contains pyrrolizidine alkaloids. Most do not mention the P450 drug interactions in goldenseal. Most do not list hypertension, gall bladder disease, seizure history, and paralysis as conditions to avoid. This brand does. The label on this product surfaces more contraindications than any other respiratory pet supplement we carry, and the manufacturer's website goes even deeper. This is what label-reading households look for. The brand has chosen to tell the truth about its ingredients rather than to compete on simplicity. The product also brings together the foundational Western respiratory canon (mullein, elecampane, coltsfoot, yarrow, mallow leaf, goldenseal) with the vet-channel formulation philosophy. The transparency credential is part of what you are buying. Honest Disclosures What you need to know before you buy. This formula has more contraindications than any other Sustenance Herbs tincture. Read every flag before deciding if it fits your dog. Goldenseal can change how prescription drugs work. The manufacturer explicitly names "P450 drug interactions" on the label. Goldenseal leaf contains berberine, which slows down liver enzymes that break down many prescription medications. That can let those medications build up higher than expected in your dog's bloodstream. Affected medications include cyclosporine, some heart medications, certain seizure medications, and others. If your dog is on any prescription, your vet needs to know before you start. Coltsfoot needs pulse cycles and a liver-support partner. Coltsfoot leaf contains pyrrolizidine alkaloids (PAs), plant compounds that can stress the liver in high doses over long periods. The leaf has lower PA content than the root, but the holistic standard is to use pulse cycles of two to three weeks rather than indefinite daily dosing. Pair the protocol with milk thistle for liver support during any cycle longer than the acute window. The manufacturer's "not for long-term continuous use" guidance is specifically designed to address this concern. Not for dogs with hypertension or gall bladder disease. Yarrow and elecampane can mildly raise blood pressure in some dogs. If your dog has been diagnosed with hypertension or is on blood pressure medication, this formula is not the right fit without close vet supervision. Separately, goldenseal and elecampane both stimulate bile flow. Dogs with gall bladder disease, gallstones, or biliary obstruction should not use this formula. Not for dogs with seizure history or paralysis. Yarrow contains trace amounts of a compound called thujone that can theoretically lower the seizure threshold. The manufacturer also names paralysis as a condition that warrants avoiding this formula. If your dog has seizure history, is on anticonvulsant medication, or has current or recent neurological concerns affecting motor function, this formula is not the right fit without specialist holistic veterinary supervision. Not for pregnant or nursing dogs. Yarrow has been used historically to stimulate the uterus. Goldenseal's berberine can cross the placenta. Coltsfoot's PA content is contraindicated in pregnancy. The combined caution profile makes this formula unsuitable for pregnant, nursing, or breeding dogs. Is This Right For Your Dog Who this tincture was built for. Strongest Match Dogs recovering from a kennel cough event. Your dog came home with the dry honking cough after boarding, daycare, the dog park, or a grooming visit. Your vet has examined her, diagnosed kennel cough, and cleared supportive home care. The household routine has shifted to give her quiet recovery time. This is the most common reason households reach for an acute herbal respiratory tincture. The two to three week pulse covers the standard recovery window for an uncomplicated kennel cough event. Strongest Match Dogs your vet is managing for chronic bronchitis or collapsing trachea. The cough is a recurring part of your dog's life. Your vet is on board with the management plan, and the integrative protocol calls for a herbal respiratory layer during flare windows. Used in three-to-four-week pulse cycles with one-to-two week rest periods, this formula joins the long-arc management your vet has set up. The exact cycle rhythm gets calibrated with your vet based on flare frequency and severity. Post-anesthesia respiratory recovery. Your dog's lungs are working harder than usual after a recent surgery. Your vet has cleared a holistic herbal layer to support the natural recovery of the airway during the post-operative window. Multi-dog households after a kennel cough exposure. One dog in the house just came down with kennel cough. The others are in the exposure window. With your vet on board, a preventive holistic herbal protocol can support the rest of the household during the watch period. Households building out their Sustenance Herbs cabinet. You already use Bor-L-Immune, AntiBact, Pet Calming Formula, or Kidney Works and trust the brand. KC Respiratory Formula is the fifth product in the line. Label-reading households. The certified organic and ethically wildcrafted sourcing, the conservation-conscious goldenseal, and the industry-leading contraindication transparency reflect your values. Households that can do all of the safety checks. Not pregnant or nursing. No hypertension. No gall bladder disease. No seizure history. No paralysis. And willing to loop in your vet for any prescription medication or upcoming surgery. The check list is longer for this formula than for any other Sustenance Herbs product. If your household clears all of them, this is the right fit. If any apply, choose a different respiratory option under your vet's guidance. How To Give It Twice-daily dosing, used in pulse cycles. The manufacturer specifies exact drop counts by body weight, given twice daily. The reference measurement is 40 drops equals 1.2 ml (about one quarter teaspoon). Dogs with any of the named contraindications should not use this product without vet supervision regardless of body weight. Manufacturer dosing by body weight. Dog Size Body Weight Drops Twice Daily Toy 5 to 10 lbs 10 drops twice daily Small 11 to 25 lbs 20 drops twice daily Medium 26 to 50 lbs 40 drops twice daily Large 51 to 80 lbs 60 drops twice daily Giant 80 lbs and above Calibrate with your vet Start at the body-weight-recommended dose on day one. If your dog is sensitive to herbal supplements, your vet may suggest starting at half the dose for the first day and working up. Pulse cycle guidance. For acute kennel cough recovery: Two to three weeks of twice-daily drops during the active recovery window. Discontinue when your vet confirms the situation has resolved. For chronic situations under vet management: Three to four weeks of twice-daily drops, followed by one to two weeks off, then back on if your vet's protocol calls for it. The rest weeks are essential for the coltsfoot and goldenseal in the formula. This product is not designed for indefinite daily use. The manufacturer's "not recommended for long-term continuous use" guidance is explicit, and the pulse approach is the holistic standard for formulas containing coltsfoot and goldenseal. Pair with milk thistle for extended cycles. Milk thistle protects the liver during any protocol containing pyrrolizidine-alkaloid herbs like coltsfoot. For acute kennel cough recovery in a healthy dog, the standard two to three week pulse may not require milk thistle. For any chronic-management cycle or extended use, milk thistle is core supportive infrastructure rather than optional. Animal Essentials Milk Thistle is the clean single-ingredient option (linked in the pairings section). Directly in the mouth. The fastest way for the herbs to absorb. Lift your dog's lip and place the drops on her gum or inner cheek. In food. Mix the drops into wet food, bone broth, or a moistened portion of kibble. The herbal taste is strong, so wet food works better than dry kibble alone. In water with the alcohol burned off. Place the drops in a tablespoon of warm water or bone broth and let it sit uncovered for 30 to 60 seconds. The alcohol evaporates. Then mix it into the food. Storage. Keep the bottle in a cool, dry place out of direct sunlight. Do not refrigerate. The amber glass protects the herbs from breaking down in light. Subscribe and save. Acute kennel cough recovery typically resolves in a single bottle over a two to three week pulse. Chronic management with pulse cycles may use one bottle every two to three months depending on cycle length and your dog's size. Works Well With Three companions for a layered respiratory protocol. The first pairing is core supportive infrastructure for this formula, not an optional add-on. The other two are essential complements for a complete respiratory protocol. Each addresses a different layer of the natural respiratory support story. Animal Essentials Milk Thistle Milk thistle is the essential liver-support partner for any protocol containing coltsfoot. The natural compound in milk thistle (silymarin) protects liver cells during periods of increased metabolic load. The pairing is the holistic standard for herbs in the coltsfoot family. For acute kennel cough recovery in a healthy dog, the standard two to three week pulse may not require milk thistle. For any chronic-management cycle or any extended protocol, milk thistle is core supportive infrastructure. Real Mushrooms Daily Dawg Whole-fruiting-body mushroom blend with reishi and cordyceps. Reishi has been the foundational TCM lung adaptogen for centuries. Cordyceps was historically used in traditional Tibetan medicine for high-altitude respiratory support and is the most-studied modern mushroom for lung function. As a daily background complement to the pulse-protocol KC Respiratory work, Daily Dawg provides a different mechanism of lung support that stacks cleanly. Sustenance Herbs AntiBact The same-brand sibling for households whose vet is managing a respiratory situation with a bacterial component. KC Respiratory Formula handles the demulcent, expectorant, and lung-supportive herbal work. AntiBact provides the broader six-herb antibacterial herbal support layer. Both are vet-channel Sustenance Herbs formulations and they stack with appropriate vet supervision. Frequently Asked Questions The questions pet parents ask before buying. Is this a treatment for kennel cough? No. This is a herbal wellness tincture to support natural respiratory function alongside your vet's care, not a treatment for kennel cough and not a cure for any respiratory infection. Dogs with kennel cough need their vet to assess severity and decide whether prescription antibiotics or cough suppressants are appropriate. This herbal tincture is the supportive layer that joins the recovery plan, not the one that replaces it. The "KC" in the product name reflects the kennel cough family of conditions the formula was built to support, not a claim that this is a treatment. What does "P450 drug interactions" mean for my dog? P450 is a family of liver enzymes that the body uses to break down many prescription medications. The goldenseal leaf in this formula slows some of these enzymes down. That can let prescription medications build up higher than expected in your dog's bloodstream. The affected medications include cyclosporine, some heart medications, certain seizure medications, certain antibiotics, and many others. If your dog is on any prescription, your vet needs to know before you start this tincture. My dog has seizure history. Can I use this for a respiratory situation? Not without specialist holistic veterinary supervision. The manufacturer explicitly names seizure history as a reason to avoid this formula. Yarrow contains trace amounts of a compound called thujone that can theoretically lower the seizure threshold. Dogs with seizure history are better supported with a different respiratory blend. Look for one without coltsfoot, yarrow, or goldenseal, under your vet's guidance. What is the concern with coltsfoot and pyrrolizidine alkaloids? Coltsfoot contains plant compounds called pyrrolizidine alkaloids (PAs). At high concentrated doses over long periods, PAs can stress the liver. The leaf used in this formula has substantially lower PA content than the root of the same plant. The formulator uses the herb in proportional amounts within a six-herb blend. The manufacturer's "not for long-term continuous use" guidance is specifically designed around this concern. The traditional reason to keep coltsfoot in respiratory formulas is that the cough-soothing value has been documented for centuries. Used in pulse cycles with milk thistle for liver support, the historical concern is manageable. If you would rather avoid the PA disclosure entirely, choose a coltsfoot-free respiratory blend under your vet's guidance. Should I add milk thistle alongside this tincture? For any protocol extending beyond a short acute recovery, yes. Milk thistle's natural compound (silymarin) protects liver cells during periods of increased metabolic load. The pairing is the holistic standard for herbal blends containing pyrrolizidine alkaloids. For acute kennel cough recovery in a healthy dog, the standard two to three week pulse may not require milk thistle. For chronic-management cycles or any extended use, milk thistle is core supportive infrastructure rather than optional. Can I give this to my dog with chronic bronchitis every day? Only with your vet's guidance, and only in cycles. The manufacturer's explicit guidance is to avoid long-term continuous use. The holistic standard for chronic bronchitis management is three to four weeks of twice-daily drops, followed by one to two weeks off, then back on if needed. Your vet helps you plan the rhythm. The rest weeks are essential for the coltsfoot and goldenseal in the formula. Continuous daily use without rest is not the recommended approach. Why does the label say "not recommended for long-term continuous use"? Because two of the six herbs in this formula (coltsfoot and goldenseal) are traditionally used in pulse cycles rather than every single day forever. Coltsfoot's pyrrolizidine alkaloids and goldenseal's berberine both belong to the herbal tradition of strong botanicals that the materia medica has historically used carefully. The holistic standard is two to three weeks of acute use, three to four weeks of chronic-management use, with rest periods between cycles. The pulse approach respects the historical use of these herbs and reduces the load on the liver over time. How does this compare to the other Sustenance Herbs products? All five are vet-formulated, certified organic, and NASC-quality-checked. Bor-L-Immune is the cryptolepis tincture for tick-borne disease support. AntiBact is the broader antibacterial herbal tincture. Pet Calming Formula is the acute nervous system tincture in a low-alcohol raw honey base. Kidney Works is the chronic kidney support tincture. KC Respiratory Formula is the pulse-protocol respiratory tincture with the most extensive contraindication profile of the five. Each addresses a distinct holistic protocol territory. Why this respiratory product over others on the market? Three reasons. First, the brand is vet-formulated for use in holistic veterinary practices, not built for the retail shelf. Second, the six-herb combination is the foundational Western respiratory canon (mullein, elecampane, coltsfoot, yarrow, mallow leaf, goldenseal leaf), not a single-herb commodity blend. Third, the contraindication disclosure is among the most comprehensive in the herbal pet supplement market. Most respiratory products do not tell you about the coltsfoot PA content, the goldenseal P450 interactions, or the hypertension and seizure history cautions. This brand does. NASC Quality Seal Six Organic or Wildcrafted Herbs Western Respiratory Heritage Veterinarian Formulated Conservation-Conscious Sourcing Non-GMO The Acute Respiratory Layer A six-herb organic tincture for kennel cough, bronchitis, and respiratory recovery. Mullein and mallow leaf coat the irritated mucous membranes of the upper airway. Elecampane and coltsfoot support the natural clearing of mucus from the deeper bronchi. Yarrow brings the anti-inflammatory and circulation support. Goldenseal leaf adds the natural antimicrobial layer. Five of the six herbs are certified organic. Yarrow is ethically wildcrafted. The whole product carries the NASC Quality Seal and is built by veterinarians for use in holistic veterinary practices. Used in pulse cycles: two to three weeks for acute kennel cough recovery, three to four weeks on and one to two weeks off for chronic management. Pair with milk thistle for liver support during extended protocols. Not for pregnant or nursing dogs, dogs with hypertension, gall bladder disease, seizure history, or paralysis. Loop in your vet if your dog is on any prescription medication. The contraindication list is longer here than for any other Sustenance Herbs tincture. Read every flag carefully. Do the safety checks. And use the herbs the way the tradition has always asked them to be used: with care, in cycles, and with your vet on board. Cough suppressants quiet the symptom. These herbs help the airway clear.
