Antimicrobial Formula


Antimicrobial Formula is the ultimate herbal blend for supporting your dog or cat's immune system and assisting their body with eliminating pathogenic organisms*. Formulated by a certified Master Herbalist using USDA organic herbs, this blend will help to support healthy white blood cell production and also provide special antimicrobial herbs to support the body when infection is a concern.

Antimicrobial can support the body's immune response* to deal with Giardia, Salmonella, E. coli and other bacteria, fungi and viruses that are common causes of diarrhea and other illnesses in our pets. Avoiding the use of antibiotics when possible (without endangering your animal) will strengthen your animal's immune system in the long run. Studies have shown that individuals that use the most antibiotics suffer with more frequent infections. You can always resort to antibiotics if your animal's condition does not improve after using this formula for a few days.

If your animal is subject to more frequent infections you can purchase extra Antimicrobial and keep it in the fridge so it is available when you need some and you may also use Astragalus Root daily to naturally strengthen your animal's immune system on a daily basis.

What to Look for in a Superior Antimicrobial Formula:

Organic Herbs

Our formula contains certified USDA organic herbs. Research shows organic herbs have higher amounts of important nutrients as opposed to conventionally raised plants. Organic farming methods are also better for the environment and of course do not have the levels of residual pesticides that conventionally grown herbs can have. We also do not use wild crafted herbs in our formulas as this practice can damage wild populations of herbs and you do not necessarily know where the herbs are coming from or how they've been grown. Instead, we prefer to be on the safe side and only obtain herbs from USDA certified organic farms.

Natural Ingredients

Natural ingredients are going to be gentler on your animal's body when compared to synthetic chemical ingredients or medications. The proper natural constituents are able to provide the body with what it needs to heal and get better. This is in direct contrast to synthetic ingredients or medications that can be especially hard on the liver and kidneys. Medications are also designed to have a symptom suppressing action in line with the principles of allopathic medicine which is to create a diagnoses and then use drugs to suppress symptoms. Using this course of action can never result in true healing and is not really meant to.

Alcohol-Free Tincture with ORGANIC Vegetable Glycerin for Animals

Our blend is formulated by a special process using low heat and organic vegetable glycerin. Tinctures are concentrated forms of a plant's constituents that are readily absorbed and utilized by your pet's body. Because your pet may not like the taste of alcohol, we use vegetable glycerin which gives our tinctures a sweet taste your animals will like. Vegetable glycerin is a carbohydrate but is metabolized differently than sugar and does not raise blood sugar levels. It is also an efficient menstruum which extracts valuable constituents from plants and makes them readily available to the body. In addition, we take the extra time and effort to use a low heat process that extracts many more constituents than just soaking in glycerin alone as is done by most other herbal companies. And, of course, the use of organic vegetable glycerin ensures your pet avoids genetically modified ingredients and herbicides in their natural medicine.

Uses only Human Grade Ingredients

Our products are manufactured using human grade ingredients. In the pet industry this is far from the rule as many companies use pet quality ingredients, those considered "not fit for human consumption".

Uses Fresh, High Quality Ingredients

We purchase our ingredients from some of the most highly regarded companies in their respective fields so you and your animals are ensured the finest quality supplements. In addition, we purchase in small quantities to make sure the products we provide to you are fresh and bursting with important nutrients. This is in direct contrast to many other products on the market that can spend a year or longer sitting in non-climate controlled warehouses before they even get to you.

A proprietary blend of USDA Organic herbs in a 1:5 ratio of herb to menstruum:

Echinacea Root (Echinacea angustifolia), Cat's Claw Bark (Uncaria tomentosa), Oregon Grape Root (Mahonia aquifolium), Garlic (Allium sativum), Oregano Herb (Origanum vulgare) and Thyme Herb (Thymus vulgaris)

Other Ingredients - Organic vegetable glycerin, distilled water. Alcohol Free!

About the Organic Herbs in this Formula

Echinacea Root Antimicrobial Remedy for Dogs and Cats 

Echinacea Root - An immune system booster that increases macrophage T-cell activity that devours invaders and acts as the body's first line of defense. We use Echinacea angustifolia in our formulas as this species is believed to be the most effective in supporting the immune system out of the three species of echinacea used in herbal medicine.

Cat's Claw Bark Antimicrobial Remedy for Dogs and Cats 

Cat's Claw Bark - Contains powerful alkaloids that stimulate the immune response and act as antioxidants to rid the body of free radicals. Compounds found in Cat's Claw may also work to kill viruses, bacteria and other microorganisms that cause disease and may work to inhibit healthy cells from becoming cancerous.

Oregon Grape Root Antimicrobial Remedy for Dogs and Cats 

Oregon Grape Root - Contains antimicrobial alkaloids that help inhibit bacteria, fungi, parasites and protozoa. Works well with echinacea to fight infections and ward off illness.

Garlic Antimicrobial Remedy for Dogs and Cats 

Garlic - The sulfur and volatile oils make this herb a potent internal antiseptic. Provides antiprotozoa, antimicrobial, cardiovascular and immune stimulatory benefits, and is considered safe for your animals at the dosages used.

Thyme Antimicrobial Remedy for Dogs and Cats 

Thyme Herb - One of the best herbs for stimulating the thymus, a major gland of the immune system. Thyme also offers antiseptic properties and when combined with echinacea helps to boost the immune system.

Oregano Antimicrobial Remedy for Dogs and Cats 

Oregano Herb - Like thyme, this herb provides antiseptic properties that helps support the immune system.

Provide 1 ml per 25 lbs 2 - 3 times per day. May be squirted directly in the mouth, placed in a small amount of favorite food (goat milk yogurt works well) or added to meals. It is desirable to provide herbal remedies such as this away from meals for better absorption when possible.

Shake well before use.

Since this is not a medication, dosages do not have to be exact. Do the best you can to get as close to the suggested dosage below as you can for your animal’s weight.

Pet Weight Dosage
0 - 5 lbs 2 - 3 drops
6 - 10 lbs 1/4 ml
11 - 15 lbs 1/2 ml
16 - 20 lbs 3/4 ml
21 - 25 lbs 1 ml
26 - 31 lbs 1 1/4 ml (1/4 tsp)
32 - 37 lbs 1 1/2 ml
38 - 43 lbs 1 3/4 ml
44 - 50 lbs 2 ml
51 - 56 lbs 2 1/4 ml
57 - 62 lbs 2 1/2 ml (1/2 tsp)

88 - 100 lbs 4 ml

For serious acute conditions - It is recommended to provide three dosages per day. When your animal is doing better you may try reducing dosages to twice daily and see how they do with that schedule. Use for approximately 7 - 14 days or until your animal is feeling better.

For chronic conditions - You may provide two to three times daily. If your animal does not respond to two dosages they will need three until they show improvement and then you may reduce to two dosages daily and see how they do. Use for up to 14 days at a time then take a week break. Repeat the cycle again if necessary. If your animal suffers from frequent infections this formula is safe to use for a week or so every month as a preventative.

Long-term use: Use for up to 14 days at a time then take a week break. Repeat the cycle again if necessary. If your animal suffers from frequent infections this formula is safe to use for a week or so every month as a preventative. You may also consider the use of Astragalus Root to support your animal's immune system long-term.

To apply directly in mouth just pull out lower lip at back of mouth and squirt in desired amount. Don't tilt head back and squirt down throat or your pet may breathe some in. Wipe off dropper before placing back in container. If your animal coughs afterwards it is a sign they are breathing some in and it may be best to place in food in the future.

How long does it usually take for this herbal remedy to work?
Well, that is a difficult question to answer because each animal and his/her situation is unique. Sometimes benefits are seen immediately within a day or two and other times it may be a couple of weeks. We would say that you should see some sort of improvement within three to four weeks. If you don’t see improvement please contact us in case we can make other suggestions - perhaps there is a more appropriate remedy etc. Remember, these are not pharmaceutical drugs that have a dramatic affect on the body. What we are trying to accomplish with our herbal remedies and other supplements is to increase the health of weak organs/systems and this can take a little time to accomplish in some cases. Also, please keep in mind that diet and lifestyle play a huge role in the health of your animal(s). If you continue to feed a poor-quality kibble diet or provide repetitive booster vaccinations or use flea/tick chemical products, these will work against what we are trying to accomplish and make it more difficult to improve the health of your dog or cat.

What if my animal is not responding as hoped?
Then you may increase the dosage by 50% and see how that works. Dosage can then be reduced at a later date. If they still do not respond as hoped then please do not just give up, instead contact us by email so we can consider your animal's condition and make further suggestions. Our goal is to succeed and we will help you to the best of our abilities.

What if I have a large dog or I am on a budget?
We understand that providing a large animal with herbal remedies and natural supplements can be a financial burden to some. We would suggest to provide what is within your budget and see how that works. For example, if you have a 100 lb dog that would require 5 mls two to three times daily, figure what is within your budget and try that. It may only be 1 ml or 2 mls two times per day. However, in our experience this is preferable to avoiding the remedy entirely.

Do these herbal remedies have any contraindications?
A contraindication suggests that a particular remedy should not be used in certain health conditions or along with certain medications. If any are present they will be indicated at the bottom of this page under Contraindications.

Can I use this herbal remedy along with my pet’s medication(s)?
Generally, the answer to this question is “yes” with some caveats. As mentioned previously, if any contraindications are present they will be indicated at the bottom of this page. In addition, keep in mind that our herbal remedies often duplicate the actions of medications. For example, our heart tonic will help to dilate blood vessels and lower blood pressure mimicking the action of certain drugs used for heart failure or high blood pressure. If this is the case, then this should be discussed with your veterinarian as the dosage of the medication may need to be lowered or may even be eliminated entirely. This must be done working in coordination with your veterinarian - please do not take it upon yourself to remove your pet’s medications. If using chemotherapy drugs please discuss this with your vet as well.

What if my vet is not receptive to using natural supplements or herbal remedies?
Well, this is a fairly common occurrence unfortunately. The decision will have to be yours on how to handle this. Try discussing with your vet how important it is to you to try a more natural approach. If this doesn’t work and they are unreceptive then you have only two choices: do it their way or find a veterinarian that you can work with to better the health of your dog or cat. We know what we’d do!

We recommend you purchase enough for at least 2 - 4 weeks to get an idea if this remedy will work for your animal. Use the chart below as a guide.

This product is amazing!

One of my dachshunds picked up giardia after a short stay at the vet...& she brought it home to my other two pups. I tried a round of heavy antibiotics ) - giardia was no match &, unfortunately, despite going through the intense treatment regimen twice, the giardia & horrible symptoms persisted.

After consulting with Maria, I ordered this product & started administering it the day it arrived. Within a few days, my dogs all had marked resolution in their symptoms & at our follow up visit w/ the vet about a month later, all had their giardiasis clear.

I so wish I had found Maria & this Antibiotic Formula BEFORE I had given the harsh antibiotics prescribed by the vet.

If you're on the fence about whether or not to order this product, or have *any* questions - the customer service & individualized attention provided by PHNC & Maria is second to none!
I can't recommend this product enough. My Jack Russell Terrier was diagnosed with Anaplasmosis after I took her into the vet for running a high fever and lethargy. She was a very sick little dog, I couldn't get her to eat or drink and she was loosing weight fast. The vet gave me a prescription for a strong antibiotic which is really hard on the tummy, so you can't give it without food or they throw up. Not a good situation at all! After doing some research I came across this site, read the article on Anaplasmosis and thought I would give it a try, had to be better than the hard drugs from the vet. I am happy to say that Holley is happy and healthy with no after effects from the tick born disease. I can only think it is because of the Antimicrobial formula and I wish I would have known about it when my Great Pyrenees was diagnosed, maybe he would be alive today if I had.
I was recommended this along with the allergy relief to give my pug who had allergic bronchitis. I did not want to put him on the meds the doctor prescribed. My dogs are on other products from here and they are amazing. We saw a huge difference in our pug after being on this a week and after 2 weeks even more. His breathing is now way better and he stopped hacking. So thankful for these amazing pure products for all our pups!!❤
Whenever my 13-year-old cat would have a vomiting episode, he'd develop a sinus infection. Typically the vet would prescribe antibiotics. With the Antimicrobial herbal remedy I can achieve the exact same antibiotic effect in my cat's sinus infection as a pharmaceutical would, but the difference is he accepts the Antimicrobial remedy easily, he isn't traumatized by a vet visit, and I have saved a fortune on vet bills and drug prescriptions simply by using the various products offered here. But what is most important to me is that by using the products offered on The Pet Health and Nutrition Center is that he is receiving treatment using organic, human grade herbal remedies that work with the body, not against it.
Called the store and spoke with Phil, who I guess formulates all the products for this company. Told him what my problem was and he suggested this product. Received it in one day and it just worked great. Within 24 hours my dog was back to her old self and I feel like I probably avoided a $300-$400 vet visit. Very helpful customer service and great products.

Antimicrobial for Dogs Customer Testimonial

I have always relied on Phil and Maria's natural protocol treatments starting when I had my precious Daisy who survived the deadly IMHA with their help a few years ago. I now have little Keiko that I recently adopted and who is bringing such joy and love to our family. We picked her up at 12 weeks old and within 3 days we found out that she had Giardia! She is a tiny and adorable Havanese that weighs a little over 4 lbs and I was so bummed to find out that she had these nasty parasites and bacterial infections within her. Her vet immediately wanted to put her on a course of antibiotics. Concerned with the side-effect of antibiotics, I sent Phil and Maria an email about Keiko's condition and within less than a day Maria responded with a recommendation to use the antimicrobial blend to address the Giardia. I told the vet that I will not use any antibiotics for treating Giardia and was informed the implications of this infection. I had the antimicrobial blend fedex'ed overnight and I immediately administered the recommended drops to Keiko with no doubt that this will completely eliminate Giardia in a gentle way as opposed to antibiotics. Right after the first 10 days, I sent another stool sample to her vet.... it was a BIG relief that the test resulted with absolutely no signs of any parasites and bacterial infections and Keiko is free of Giardia!!! Her vet asked about the treatment and took a picture of the antimicrobial bottle! We are on the 10 day break but will immediately resume the last 10 days of antimicrobial drops as a precaution for Keiko.
I couldn't thank Phil and Maria enough for rescuing my little Keiko with their antimicrobial Giardia protocol. I am very grateful that both Phil and Maria are always there for me (with Daisy before and now Keiko) and their passion about helping me raise a healthy fur baby. Thank you so much Phil and Maria!
