Sustenance Herbs
A six-herb certified organic tincture for the long, slow work of getting your dog back to steady. A blend of organic herbs that traditional herbalists have used for centuries to support the body's own natural antibacterial wellness response.
Why Holistic Households Reach For This
You know your dog. You can tell when something is just a little off. Maybe she had a tick bite a few years back and your vet has been watching her bloodwork ever since. Maybe she finished a course of antibiotics months ago and her energy still has not quite come back. Maybe she has had one ear infection or one skin flare-up after another, and you are tired of treating the symptom without supporting the bigger picture. Or maybe she is your healthy hiking partner and you want to keep her that way through tick season.
AntiBact is the natural herbal tincture holistic vets reach for in moments like these. Six certified organic herbs work together to support your dog's own immune system as it does the long, slow work of getting back to a steady baseline. You add a few drops to your dog's food once a day. The herbs do the rest. Most households use it in cycles, three to four weeks on and one week off, on the advice of their holistic vet.
The brand is small-batch and built by veterinarians for use in holistic veterinary practices. The formula is grounded in Stephen Harrod Buhner's well-known Healing Lyme research, which is the most respected work in holistic tick-borne disease care. Every herb in the bottle is certified organic. The goldenseal is farmed instead of taken from the wild, in respect of its conservation status. The whole product carries the NASC Quality Seal, an independent check on the label and the manufacturing process.
What this is: a natural herbal tincture to support your dog's wellness as part of holistic care. What this is not: a veterinary antibiotic, a treatment for an active infection, or a cure for any disease. If your dog has an active diagnosed infection, your vet is the first call. AntiBact is what holistic households add alongside or after that care.
A few quick safety notes before you keep reading. This tincture is for dogs only, not cats. It is not safe for pregnant, nursing, or breeding animals. If your dog is on any prescription medication, your vet needs to know before you start. The full set of cautions is spelled out in plain English further down the page.
Antibiotics end the active battle. These herbs prepare the body for what comes next.
Why Six Herbs, Why Cycles
There is a reason this formula uses six herbs instead of one or two, and a reason herbalists use whole-plant extracts instead of just one isolated compound. Holistic herbalists have followed three rules for a long time. They line up with what modern holistic vets see in practice every day.
One strong herb is not enough. Every antibacterial herb has its own strengths and gaps. Goldenseal handles some bacteria really well, but not others. Neem handles different ones. Cat's claw works on the immune system in its own way. Putting six herbs together gives your dog much broader support than any single herb could. It also makes the work harder for bacteria to dodge, which matters in long-term situations.
Use the whole plant, not just one compound from it. A whole-plant tincture has dozens of natural compounds working together. That is gentler on your dog's body. It is also harder for bacteria to outsmart, because they would have to figure out how to evade many compounds at once instead of just one. AntiBact uses whole-plant tincturing for all six herbs.
Work on the long arc, not the quick fix. Strong herbal blends like this one are not used for two or three days the way a prescription might be. The holistic tradition uses them across weeks and months, usually in cycles of three to four weeks on and one week off. The cycles give the liver a rest and let the gut bacteria rebalance. Your vet can help you plan the right cycle for your dog.
When To Reach For This
Cat's claw and andrographis are the two main herbs in the Buhner Lyme protocol. The other four herbs add broader support for the long recovery after a tick bite or a Lyme diagnosis.
Antibiotics handle the urgent problem, but your dog's body often needs more time to feel like itself again. This tincture supports that recovery window.
Skin flare-ups, ear flare-ups, mouth or urinary issues that keep coming back. While your vet figures out the bigger picture, this tincture helps support your dog's natural defenses.
Every herb is certified organic. The goldenseal is farmed instead of wildcrafted, which protects a plant that has been overharvested. The label reflects your values.
Working dogs, hunting partners, and weekend hiking buddies face more exposure than couch potatoes. A daily herbal layer helps keep their immune system steady through busy seasons.
Already using Bor-L-Immune from the same brand? AntiBact is the natural next step. The two products were designed to work together in the Buhner-style protocol holistic vets recommend.
What Is In The Bottle
Featured Herb
Cat's claw is a woody vine from the Amazon rainforest. The Asháninka people of Peru have used it for hundreds of years for immune support. The plant's natural compounds (called POAs, short for pentacyclic oxindole alkaloids) are what modern research has studied.
Here is the simple way to think about cat's claw. Most herbs and medicines tell the body what to do. Cat's claw teaches the body to respond better to what it is already dealing with. That makes it useful for the slow, chronic situations where your dog's immune system has been working overtime for a long time. Cat's claw is one of the two main herbs in Stephen Harrod Buhner's Lyme protocol, and it is the most-researched herb in that protocol.
Honest cautions. Do not use in pregnant or nursing animals. If your dog is on medication for blood pressure, blood clotting, or anything that affects the immune system, talk to your vet before starting.
Featured Herb
Andrographis is called the "king of bitters" in Ayurvedic and Chinese medicine because its leaves are so bitter. It has a long reputation as one of the strongest immune-support herbs in traditional medicine. The active compounds are called andrographolides, and they have been studied in modern research for their effects on the immune system.
Bitter herbs wake up the immune system in a way that gentler herbs cannot. Andrographis is at the strong end of that scale. It is the second of the two main herbs in the Buhner Lyme protocol, alongside cat's claw, and modern research has looked at it in many different situations.
Honest cautions. Andrographis can lower fertility in research animals, so it is not safe for pregnant, nursing, or breeding animals. It can also lower blood pressure and affect blood sugar. If your dog is on medication for either, talk to your vet first.
Oregon grape root grows in the Pacific Northwest. Its bright yellow root contains berberine, a natural compound used in Western, Ayurvedic, and Chinese herbal medicine for centuries. Berberine works on bacteria in several ways at once, which is why herbalists reach for it when the body needs broad support.
Goldenseal is a North American herb that the Cherokee, Iroquois, and other Indigenous nations used for generations. Western herbalists picked it up in the 1800s. The root carries berberine plus other natural compounds that make it one of the strongest antibacterial herbs in traditional medicine. Wild goldenseal has been overharvested for over a century, so it is now on an international conservation list. Responsible brands grow it on farms instead of taking it from the wild. Sustenance Herbs is one of those brands.
Honest cautions. Berberine slows down some of the liver enzymes that break down prescription drugs. That means your dog's medication could build up higher than expected in the bloodstream. If your dog is on any prescription, talk to your vet before starting. These herbs are also not safe for pregnant or nursing animals.
Neem is the broad-spectrum Ayurvedic herb that traditional Indian medicine has called the "village pharmacy" for thousands of years. The leaf is the part used in this tincture. It carries a complex mix of natural compounds that traditional and modern research has studied for fighting bacteria, fungi, and parasites.
Neem's complexity is the point. A single isolated compound is easier for bacteria to develop resistance to. A whole-leaf tincture with dozens of compounds is much harder to outsmart. That is the strongest argument for using whole-plant tinctures in long protocols like this one.
Honest cautions. Neem is not safe for cats. This is one of the main reasons this tincture is for dogs and horses only. Neem is also not safe for pregnant, nursing, or breeding animals. For dogs without those concerns, neem is usually used in cycles rather than continuously.
Usnea is not technically a plant. It is a lichen, a partnership between a fungus and an alga that grows together as one organism. You may know it as "old man's beard," the stringy growth that hangs from tree branches in clean forests. Lichens will only grow where the air is clean, which is why herbalists pay close attention to where their usnea comes from.
The active compound is usnic acid, which has been studied for fighting certain types of bacteria that conventional approaches sometimes struggle to reach. This includes some of the biofilm-forming bacteria that hide inside protective coatings during chronic infections.
Honest cautions. Concentrated isolated usnic acid extracts have been linked to liver injury in research. This is why herbalists use usnea in whole-tincture form, in moderate amounts, and in cycles rather than every single day. If your dog has liver issues or is on medications that affect the liver, talk to your vet first.
What This Looks Like For Your Dog
Picture your six-year-old retriever who has been carrying something quietly for a long time. Maybe she had a tick bite two years ago and your vet has been watching her bloodwork ever since. Maybe she had a course of antibiotics that handled the acute problem but left her energy not quite where it used to be. Maybe she has been dealing with recurring ear, skin, or urinary issues that your vet has been working through. Or maybe she is your healthy working dog and you want to keep her at her best.
Once you start adding daily drops to her food, here is what tends to happen inside her body when six herbs are working together with her own natural immune system.
Cat's claw teaches the immune system to respond better
Your dog's natural ability to recognize and respond to low-grade activity gets stronger, without pushing the immune system into overdrive.
The berberine herbs deliver broad antibacterial support
Oregon grape root and goldenseal work on many types of bacteria at once. Usnea adds support for some of the harder-to-reach types.
Neem broadens the coverage even further
The dozens of natural compounds in neem leaf add another layer of broad support that is hard for organisms to dodge.
Usnea reaches into the hard-to-find spots
Some bacteria hide inside protective coatings called biofilms. Usnea is one of the few herbs that can reach into those spots.
Andrographis wakes up immune signaling
Your dog's natural inflammatory response gets supported, without shutting down the work her immune system still needs to do.
Her liver carries the workload
Six herbs is a lot for any liver to process. This is why pairing AntiBact with a liver-support product and using cycles (three to four weeks on, one week off) is the standard holistic approach.
Over weeks and months, the picture improves
Pet parents working with holistic vets often notice that their dog has steadier energy, fewer recurring flare-ups, and a more stable baseline than before.
The Quality Standard
Every herb in the bottle is certified organic, including the goldenseal, which responsible brands grow on farms instead of wildcrafting.
An independent group, the National Animal Supplement Council, has checked the label, the manufacturing, and the ingredients against industry quality standards.
The goldenseal is grown on farms instead of taken from the wild, in respect of the plant's protected status under international conservation rules.
Distilled water and gluten-free organic grain alcohol pull out the full natural mix of compounds from each herb, the way traditional herbalists have always made tinctures.
Sustenance Herbs builds its formulas with veterinarians, for veterinarians. The product is used in holistic and integrative practices across the country.
Light-protective amber glass with a glass dropper. No plastic touches the tincture, which protects the herbal compounds from breaking down over time.
Why Holistic Vets Trust This Brand
Sustenance Herbs combines three things that are hard to find together in one product. First, the brand is built by veterinarians for use in holistic veterinary practices. The people who recommend this product are the same kind of people who built it. Second, the formula is built on Stephen Harrod Buhner's Healing Lyme research, which is the most respected work in holistic tick-borne disease care. Third, every herb is certified organic, including the goldenseal, which most commodity brands still take from the wild despite its protected conservation status. You are buying a product with a documented herbal tradition, named research, and real conservation commitments behind it.
Honest Disclosures
This is a wellness tincture, not a veterinary antibiotic.
AntiBact does not treat or cure a bacterial infection. If your dog has an active, diagnosed infection, your vet is the first call. This tincture is meant to support your dog's wellness alongside or after that care, with your vet on board.
Not for cats. Not for pregnant, nursing, or breeding animals.
Neem is not safe for cats. Their livers process plant compounds differently from dogs, and some compounds that dogs handle well are dangerous for cats. Cat's claw, neem, goldenseal, and andrographis each carry warnings against use in pregnant, nursing, or breeding animals. If your household includes any of these, this is not the right product.
Drug interactions are real. Loop in your vet.
Berberine in oregon grape root and goldenseal slows down liver enzymes that break down many prescription drugs. That means your dog's medication could build up higher than expected in the bloodstream. Cat's claw and andrographis can also affect blood pressure, blood sugar, and the immune system. If your dog is on any prescription, your vet needs to know before you start.
Use in cycles for long-term protocols.
Several of these herbs are traditionally used in cycles rather than every single day forever. The standard pattern is three to four weeks on, one week off. The week off gives your dog's liver a rest and lets the gut bacteria rebalance. Your holistic vet will help you plan the right cycle.
Cannot ship to Vermont.
Vermont has a state law (Title 6, Chapter 26) that requires extra registration steps for some veterinary products. Sustenance Herbs has chosen not to register every product with Vermont, so this one cannot ship there. If you are in Vermont, contact us and we can suggest other holistic options.
Is This Right For Your Dog
Strongest Match
Your dog had a tick bite, has a confirmed Lyme diagnosis, or has bloodwork that your vet has been keeping an eye on. You have done your reading on the Buhner protocol. You want the strongest certified organic herbal layer your holistic protocol can include. AntiBact and its sibling Bor-L-Immune (the cryptolepis tincture that targets Lyme specifically) form the strongest two-product certified organic herbal stack in our catalog, used with your vet on board.
Strongest Match
Your dog finished a prescription antibiotic course. The acute issue is handled, but the recovery window is real. Her gut bacteria, her energy, and her immune balance all need time to rebuild. Your holistic vet is open to adding herbal support alongside the conventional care. This is the natural moment to start a daily certified organic herbal tincture.
Working, sporting, or hunting dogs. Your dog has more environmental exposure than the average couch potato. A daily herbal layer in cycles helps keep her immune system steady through busy seasons.
Recurring low-grade flare-ups. Skin, ear, urinary, or mouth issues that keep coming back. Your vet is working through the bigger picture, and you want to support your dog's natural defenses while that work happens.
Label-reading households. Certified organic sourcing, conservation-conscious goldenseal, and clear contraindication disclosure matter to you. The label tells you exactly what you are buying.
Dogs and horses only. If your household has no cats, no pregnant or breeding animals, and you are willing to coordinate with your vet on any prescription medications, this is a good fit. If any of those situations apply, this is not the right product.
How To Give It
The standard dose is one drop per pound of body weight, once a day, or as your vet recommends. The 2 fl oz bottle holds about 2,000 drops, which is roughly a 40-day supply for a 50-pound dog at full dose. Horses follow a separate dosing protocol from your equine vet.
Start at a lower dose the first week and work up to the full amount. This gives your dog's body time to adjust to the herbs.
Strong herbal blends like this are traditionally used in cycles instead of every single day forever. The standard pattern is three to four weeks of daily drops, then one week off, then back to three to four weeks of daily drops if your dog needs more.
The week off gives your dog's liver a rest and lets her gut bacteria rebalance. Your holistic vet is the right person to help you plan the cycle for your specific situation, and to recommend adding a liver-support product and a probiotic alongside the AntiBact cycle.
Directly on the gums. The fastest way for the herbs to absorb. Lift your dog's lip and place the drops on her gum.
In food. Mix the drops into wet food, bone broth, or a moistened portion of kibble. This works well for picky-mouth dogs and dilutes the alcohol taste.
In water with the alcohol burned off. Place the drops in a tablespoon of warm water or warm bone broth, then 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 the light.
Subscribe and save. A 50-pound dog at the full dose uses one bottle every 40 days. A three-weeks-on, one-week-off cycle uses one bottle every 53 days. The subscription cadence can be adjusted to match your dog's protocol.
Works Well With
These three pairings are not nice-to-haves. They are the support team that holistic vets pair with any strong herbal antibacterial protocol. The sibling brand product extends the Buhner-style support. The liver formula gives the liver the raw materials it needs to process the herbs. The probiotic keeps the gut bacteria in balance during and after the cycle.
This is the same-brand sibling product for any Buhner-inspired Lyme protocol. Bor-L-Immune is built around cryptolepis, an African herb that 2020 Johns Hopkins research found more effective than doxycycline in lab studies of the Lyme spirochete. AntiBact is the broader antibacterial herbal layer. Together, with your vet on board, they form the strongest two-product certified organic herbal stack we carry.
Liver support is essential during a long herbal protocol. Six antibacterial herbs is a lot for any liver to process. This formula has milk thistle, dandelion root, phytosome curcumin, and the natural building blocks the liver uses for its own detox work. Holistic vets pair it with AntiBact regularly. This is not optional. It is the support your dog's liver needs to keep up.
The probiotic side of the support team. The same herbal activity that supports your dog's natural balance against problem bacteria also shifts her gut bacteria. Fido's Flora delivers probiotic strains identified from healthy dog guts (not human, soil, or dairy sources), which helps keep the gut in balance during the AntiBact cycle and rebuild it during the week off.
Frequently Asked Questions
No. AntiBact is an herbal wellness tincture, not an antibiotic. If your dog has an active, diagnosed infection, your vet is the right first call. This tincture is meant to be used alongside or after that care, not instead of it. Holistic households use it for the long, slow situations: chronic flare-ups, antibiotic recovery, tick-borne disease support. It is not meant for quick acute treatment.
Yes, and that is the most common Sustenance Herbs protocol. AntiBact and Bor-L-Immune were designed to work together in Buhner-style Lyme protocols. Bor-L-Immune is the cryptolepis-focused layer that targets the Lyme spirochete specifically. AntiBact is the broader antibacterial herbal support. Use both under your vet's supervision, especially if your dog is also on prescription doxycycline. The herbs in AntiBact can interact with several prescription medications, and your vet needs the full picture.
Neem is not safe for cats. Cats process plant compounds very differently from dogs. Some compounds that dogs handle without trouble can cause real harm to cats at the same dose. Several other herbs in the formula also carry warnings for cats. Sustenance Herbs makes other products that are safe for cats. AntiBact is not one of them.
Only with your vet's go-ahead. Berberine (in oregon grape root and goldenseal) slows down liver enzymes that break down many prescription drugs. That can make medication build up higher than expected in your dog's system. Cat's claw and andrographis can also affect blood pressure, blood sugar, and immune signaling. Your vet can manage these interactions, but cannot do it without knowing what herbs your dog is getting.
Most holistic herbalists use this kind of strong blend in cycles. The standard pattern is three to four weeks of daily drops followed by one week off, then back on if your dog needs more. The week off gives the liver a rest and lets the gut bacteria rebalance. The Sustenance Herbs label does allow for daily use, but the right pattern for your dog depends on her situation. Your holistic vet can help you plan.
Wild goldenseal has been overharvested in eastern North America for over a century, and the plant is now on an international conservation list. The traditional Indigenous knowledge around goldenseal was built on sustainable harvest, which the commodity herbal industry largely abandoned. Responsible brands today grow goldenseal on farms instead of wildcrafting it. Sustenance Herbs is one of those brands. This is one of the choices that separates a serious holistic brand from a commodity blend.
Vermont has a state law that requires extra registration steps for some veterinary products. Sustenance Herbs has chosen not to register every product in Vermont, so this one cannot ship there. It is a regulatory issue, not a safety concern. If you are in Vermont, contact us and we can suggest other holistic options that do ship to your state.
The base is gluten-free organic grain alcohol, and the alcohol in a per-drop dose is very small. The alcohol does important work: it pulls out the herbal compounds that water alone cannot reach, and it preserves the tincture without synthetic preservatives. If you want to minimize the alcohol exposure, place the daily drops in a tablespoon of warm water or bone broth and let it sit uncovered for 30 to 60 seconds. The alcohol evaporates and the herbs stay.
Three reasons. First, the brand is built by veterinarians for use in holistic veterinary practices, not for the retail shelf. Second, the formula is grounded in the Buhner Lyme protocol, with two of the six herbs (cat's claw and andrographis) as the recognized foundation of that protocol. Third, every herb is certified organic, including the goldenseal, which most commodity brands still take from the wild. Other products may match on one or two of these. Sustenance Herbs matches on all three.
The Holistic Herbal Layer
Cat's claw and andrographis are the two main herbs in the Buhner Lyme protocol. Oregon grape root and goldenseal carry berberine, the natural compound at the center of so many traditional antibacterial blends. Neem brings the broad-spectrum Ayurvedic layer. Usnea reaches into the spots other herbs cannot. Every herb is certified organic. The goldenseal is farmed, not wildcrafted. The whole product carries the NASC Quality Seal and is built by veterinarians for use in holistic veterinary practices.
For dogs and horses only. Not safe for cats, pregnant or nursing animals, or breeding animals. If your dog is on any prescription medication, loop in your vet first. Used in cycles for long-term work, alongside a liver-support product and a probiotic. If your household is working with a holistic vet on tick-borne disease, antibiotic recovery, recurring flare-ups, or a wellness layer for a working dog, this is a clean place to start.
Antibiotics end the active battle. These herbs prepare the body for what comes next.
