Don’t be fooled. Parsley Piert has nothing to do with the green stuff you’d find on top of a fancy meal. Instead, it’s a plant that has long been used in herbalism for bladder and kidney issues. Today, pet parents can use Parsley Piert for pets thanks to veterinarian-approved supplements such as NHV Tripsy.
But before we get ahead of ourselves, let’s take a closer look at what this plant is, how it may support urinary health in cats and dogs, and why it earned the strange nickname “stone piercer.”
Parsley Piert, also known by its scientific name Aphanes arvensis, is a sprawling plant that grows throughout the British Isles.
But Aphanes arvensis and Parsley Piert aren’t the only names that this plant can claim. It actually used to be called “stone piercer!” Why? Well, there are two reasons. The first is that Parsley Piert loves to grow in the cracks of rocks. To some, it almost looked like Parsley Piert was piercing right through the stone, causing it to crack! While this isn’t really the case – the plant just loves to grow in existing crevices – it’s still a great homage to this small yet mighty herb.

The name is also a nod to its traditional use in herbalism as an aid for kidney stones. In truth, this plant isn’t related to culinary parsley at all!
Fast forward to today, people still reach for Parsley Piert when they have kidney or bladder issues. Even pet parents can find supplements containing Parsley Piert to help support pets with kidney stones alongside regular veterinary care.
Parsley Piert has a long history of use in folk medicine. In fact, it was sometimes called “colicwort” or “bowel-hive-grass” (with hive referring to inflammation) because it was also used for intestinal issues.
However, one of the most popular uses of this small but mighty herb is as a support for kidney stones. It is believed to help support the normal functioning of the kidney and bladder.
Science is now starting to look at this herb more closely. One study even suggests that Parsley Piert has some benefits thanks to its naturally occurring antioxidants. They wrote that Parsley Piert “has a potential source of antioxidants of natural origin since especially the aqueous extract has very low cytotoxic activity. Thus, A. arvensis might be a good candidate for further investigation in developing new antioxidants.”
Parsley Piert is non-toxic to pets. However, pet parents should not try to guess the dose they give their pets. Instead, they should use veterinarian-approved supplements such as NHV Tripsy.
It should also be noted that the unrelated culinary parsley (Petroselinum crispum) can be toxic to animals and should not be confused with Parsley Piert.
Common uses of Parsley Piert for pets include supporting the kidneys, urinary tract, and the bladder.

The multi-herb formula NHV Tripsy, which contains Parsley Piert, has been studied on cats and dogs, with results suggesting promising benefits.
According to the study’s lead, Dr. Joe Bartges, “When [NHV Tripsy is] given to young cats and adult dogs, in a relatively short period of time of two weeks, the collected urine samples indicated that Tripsy significantly decreased the risk of developing urinary stones in both groups.”
The dosage and quality of the herbal ingredient are crucial for safety and efficacy. We advise against using any herb without proper guidance and under the supervision of your pet’s veterinary team. NHV formulas are meticulously researched and made in a GMP-certified facility using only the highest quality organic or ethically harvested herbs. Each formulation was expertly developed by a holistic veterinarian and a master herbalist with a combined 50 years of experience in plant-based remedies. Through dedication and research, NHV formulations are safe and effective in extracting the medicinal properties of the herb through a patented process.
NHV Tripsy incorporates Parsley Piert to support smooth urinary function in dogs and cats. It is a veterinarian-approved and 100% natural formula in a base of purified water and plant-derived glycerin.
Rich in natural antioxidants, Parsley Piert works in this formula to help support the delicate lining of the urinary tract during times of irritation.

Along with Parsley Piert, NHV Tripsy features Gravel Root, Marshmallow Root, and more to support urinary comfort and encourage balance.
NHV Tripsy can be used alongside veterinary care to provide additional holistic support from nature. Pet parents commonly use NHV Tripsy for:

Sometimes it can be tough to know what is bothering your four-legged friend because no two pets are alike! But a health issue that affects many of our feline and canine friends are bladder stones and urinary tract crystals. Stones are often triggered by an infection, but may also develop from kidney or liver disease, high blood calcium levels, improper diet, or genetics. Bladder stones tend to be smooth while crystals tend to be smaller and more jagged. So to help the body dissolve and flush calculi, Tripsy and Milk Thistle work together to strengthen the liver, help relieve inflammation, and promote urinary tract health.
To find out if your pet has urinary tract issues, have your vet run some tests like radiographs, CT scans, or ultrasounds to further investigate their symptoms and, from there, recommend an appropriate care plan.
Urinary crystals and stones can cause a lot of discomfort and stress for your furry friends. Ingredients like parsley piert, stone root, and gravel root have been used for centuries to support urinary tract health by encouraging the natural elimination of stones and helping to prevent urinary tract infections (UTIs). The diuretic and antimicrobial properties in Tripsy gently increase urine flow to keep things moving and help stop the formation of stones in the first place. Along with Tripsy's healing properties, Milk Thistle adds antioxidant support to help strengthen liver detoxification, encourage cell regeneration and soothe inflammation.
At NHV, we know that your furry friends are your family so we have made it our mission to provide the best natural supplements possible! Our master herbalist and holistic vet have created all of our formulations to be bioavailable and easy to administer in liquid form! For any questions about your furkiddo’s urinary tract health, our NHV Pet Experts are here to help!

Some of our furry friends get abandoned in their golden years due to recurring health issues like having accidents in the house. If they are suffering from bladder stones or a UTI, they may need to use the bathroom more frequently and can’t always hold it!
Let’s face it, no one wants to see their furkiddos suffer. A common health problem amongst our furbabies is bladder stones (struvite and oxalate) or a urinary tract infection (which is usually in the bladder). Stones may be caused by an infection, kidney or liver disease, genetics, high blood calcium levels, or a poor diet. To help your little one’s body flush out the stones, our Bladder Strength and Urinary Tract Health Kit contains Tripsy, Milk Thistle and Yucca to help promote gentle detoxification, help soothe inflammation, and promote healthy urine flow.
Bladder stones and urinary issues can cause a lot of discomfort and stress for your little one. A feline urinary tract infection and dog bladder infection symptoms may include: bloody urine, straining to pee, frequent urination and a strong odor.
Breeds at a higher risk of developing bladder stones are: the Shih Tzu, Yorkshire Terrier, Labrador Retriever, and Dachshund.
Your furkiddo’s health and wellness means everything to us. For our pet bladder and urinary tract health kits, we have worked with a holistic veterinarian and a master herbalist to formulate gentle yet effective remedies to focus on the areas of the body most affected by cat and dog bladder infection symptoms or urinary crystals.

Cystitis in cats and dogs is a general term for inflammation of the bladder and applies to a number of different urinary tract disorders.
If you have ever searched blood in dog urine or blood in cat urine, hematuria (blood in urine) is a very common symptom with Cystitis and requires immediate medical attention! Other symptoms of cystitis include straining to urinate, depression, lethargy, and the need to urinate frequently.
Bladder inflammation and urinary tract discomfort may be a source of depression for your furry friend. Our Cystitis Kit for Bladder Inflammation Relief contains Tripsy, Milk Thistle, and Turmeric. These 3 all-natural supplements work together to strengthen the liver and kidneys, help soothe inflammation, encourage healing and support healthy urinary tract function.
