If you’re researching ways to help your fur kiddo with kidney or bladder stones naturally, then you may have come across gravel root. This purple-flowered perennial has been used in traditional herbalism for centuries for urinary system wellness. But best of all, you can also use gravel root for pets – but only in a supplement made specifically for them. Learn why below!
Gravel root is known by a few names. Its scientific name is Eutrochium purpureum, but people also call it sweet Joe Pie weed, queen of the meadow, and kidney root. But what exactly is it?

It’s a medicinal plant that thrives in damp woodlands and meadows. It’s commonly found along the East Coast of North America. During the summer, it blooms beautiful purple flowers that give off a slight vanilla-like scent.
Gravel root has long been used in North America. It has been used to help pass kidney stones, for bladder and kidney infections, to help remove waste and toxins from the kidneys, and to help with fevers. Today, gravel root is used by holistic veterinarians to help treat pets with a variety of kidney and bladder issues.
Gravel root has been used in herbalism for 100s of years, having been used by North American Indigenous peoples for a variety of reasons.
Its traditional uses include:
By far, its most popular use is as a natural herb to support the flushing of kidney and bladder stones, hence the name gravel root.
Some scientific research has now been done on gravel root. For example, one study found that it may help ease inflamed tissues.
NHV Tripsy, our natural pet supplement that features gravel root as one of its ingredients, has also been studied in a clinical setting. Students at The University of Georgia College of Veterinary Medicine conducted a double-blind study of NHV Tripsy on both dogs and cats.
In both studies, the Relative Super Saturation (RSS) for struvite crystals was significantly lower for the supplement group compared to the placebo group! Basically, this means that they observed a positive effect when using NHV Tripsy for helping pets with urinary crystals.
Gravel root is not toxic to pets. However, you should not give your pet supplements meant for humans. If you give them supplements meant for humans or try to dose it yourself, you could be overdosing them. Instead, give them a supplement designed specifically for pet bodies, like NHV Tripsy.
NHV Tripsy is our supplement for all things bladder-related. It’s a vet-formulated supplement designed to help flush the system gently and encourage urinary system wellness. Ingredients like marshmallow root provide a protective layer to irritated tissues, while Echinacea and Oregon grape offer natural defense against microorganisms that can cause infections.
It’s also been a part of many pet parent success stories. For example, sweet Timmy takes NHV Tripsy for age-related kidney support.
Remember, 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.

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!

Powerful Support for Your Dog or Cat
Kidney issues can be really hard on pets and pet parents. The signs that your cat or dog is suffering from kidney disease or kidney failure include lethargy, weight loss, dehydration, frequent urination, and vomiting. Supporting your pet’s kidneys with gentle all-natural supplements can help them with symptoms of kidney disease and help improve their quality of life.
How NHV Remedies Provide Kidney Support for Cats and Dogs
NHV’s Kidney Support Kit for dogs and cats is used to help pets with moderate to severe chronic kidney disease and kidney failure by flushing the kidneys of impurities and improving kidney function.
The four supplements in this comprehensive kit support the kidneys in several important ways. The Omega 3 fish oils in PetOmega 3 have excellent anti-inflammatory properties, specifically for the kidneys. Omega 3 fatty acids may also help reduce proteinuria (protein lost from the kidneys expelled through the urine).
Milk Thistle has strong antioxidant and detoxifying properties that may help promote cellular regeneration, repair the liver, and offer extra support to the kidneys.
Turmeric has an outstanding list of helpful benefits as an anti-inflammatory, antioxidant, antifungal, antibacterial, antiseptic, and astringent.
Tripsy™ is NHV’s main kidney support supplement. It has been studied at the University of Georgia for its potential benefits for pet health. It contains even more beneficial herbal ingredients, including Stone Root, Parsley Piert, and Gravel Root that help prevent the formation of kidney stones (kidney calculi).
Powerful Comprehensive Benefits
Order the NHV Kidney Support Kit for Dogs and Cats to provide comprehensive support in addition to their vet-recommended treatment.
