Passionflower for Dogs, Cats, and Other Critters: A Natural Ally for Relaxation
Herbs For Pets 2 min read
When it comes to keeping our pets calm and relaxed, nature has plenty of tools to offer. One such tool is passionflower. Not only is it a beautiful herb, it is a calming one too!
So, if you want to deal with thunderstorm nervousness or vet trip meltdowns, passionflower might be just what your fur kiddo needs!
Passionflower’s History
Passionflower (Passiflora incarnata) has been used for centuries, with Native American tribes first turning to it for relief from anxiety and insomnia. Its calming properties quickly caught the attention of European settlers, who began using it in the 17th century to treat a range of ailments.
The plant’s striking flowers inspired its name and helped spread its use across Europe, where it became a trusted remedy for nervous tension and stress. By the 1800s, passionflower was well-established in herbal medicine.

Today, passionflower is still valued for its ability to ease stress and improve sleep, with modern research backing up what ancient peoples first discovered: it’s a natural way to unwind.
Benefits of Passionflower for Pets
The benefits of passionflower extend beyond people – it includes dogs and other critters! In fact, researchers have even once found that it may perform similarly to certain anti-anxiety meds.
Unlike some sedative medications, passionflower is a natural, non-habit-forming remedy. This makes it a safe and sustainable option for long-term stress management, so your pet can feel their best without the worry of dependency.
Best of all, it helps pets with restlessness – and sleep is one of the most important things for your fur kiddo’s wellness and happiness!
Safety of Passionflower for Dogs and Other Pets

Pets generally well-tolerate passionflower. However, as always, we recommend talking to your vet before introducing any new supplement to your pet’s routine. And like any herb, do not give it to pets who are pregnant or lactating.
The dosage and quality of the herbal ingredients 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.
How to Start Passionflower for Dogs, Cats, and Other Critters
If your pet struggles with anxiety or you’re preparing for upcoming travel, get-togthers, or vet visits, introducing a natural supplement into their routine could be a game-changer. NHV Lesstress is holistic, all-natural solution to help your pet stay calm and comfortable without relying on harsh chemicals.

Holistic Support for Rescued Puppies and Kittens
Giving a rescued pet a second chance at life is a beautiful thing to do! So many young pets are rescued from terrible situations or surrendered to shelters, so they may experience a lot of stress going from one place to another. Small changes can feel incredibly stressful for animals which can present as destructive or aggressive behavior. Unfortunately for rescued pets, it is hard to know what environment they were in or what they were eating before coming home with you. Foodwise, they may have been eating low-quality processed food that is missing essential nutrients or maybe they were malnourished (from living on the streets). To help ease your new furry friend into their forever home, we recommend adding natural supplements to their daily meals after they have been vaccinated and weaned. This preventative care plan is beneficial for supporting their overall health and to help slow down or prevent chronic illness (which may develop due to age, genetics, or environment). NHV Shelter Pet Happy Starter Hit contains Matricalm, Multi Essentials, and Plantaeris. This bundle of natural supplements has been formulated to calm stressed and anxious pets, help fill nutritional voids, and support quick recovery from diarrhea (which is prone to happen in young animals). To learn more about caring for your new furbaby, read our post on simple steps for a healthy puppy or kitten.
How NHV Supplements Provide A Comprehensive Adopted Puppy Kit and Kitten Kit
Changes in your new puppy or kitten’s environment can cause a lot of anxiety, especially if they are super sensitive (some breeds of dogs and cats are more prone to stress) or have experienced trauma. To express this nervous energy, they may exhibit destructive or aggressive behavior. To help ease your fluffy friend into their forever home, Matricalm’s blend of herbs like passion flower, chamomile and valerian contain soothing properties that may relax the body and improve the feeling of relaxation while the smell of lemon balm may instantly calm your pet’s nerves. Multi Essentials is like a multi-vitamin for pets. It helps to fill nutritional voids (especially for malnourished pets) and supports essential processes like blood pressure and metabolism. Puppies and kittens have very sensitive tummies so if you’re trying out different foods for them, or they mischievously snack on things they aren’t supposed to, Plantaeris’ blend of ingredients help to relax muscle cramping and helps lubricate delicate intestinal mucosa to aid proper digestion and help restore healthy bowel movements.

To be taken twice daily. (Each supplement) Determine your pet’s weight and then use the easy chart below to determine the correct dose. This is the minimum dosage.
Pet's Weight Dosage
0 - 15 lb = 0.5 ml
16 - 30 lb = 1.0 ml
31 - 45 lb = 1.5 ml

61 - 75 lb = 2.5 ml
Over 75 lb = 3.0 ml
For small animals (rabbits, ferrets), avians and reptiles use 1 drop for every 2 lb of body weight.
Long term use: Feed recommended dosage every other day (1 day on 1 day off). If used in large dosages or over a long period of time it may become irritating to the stomach lining. Some pets may require a larger dosage due to their metabolism. You can safely double the recommended dosage.
How to Administer: Shake well before use. The easiest method is to use the dropper provided and place the drops into your pet’s food or favorite treat. You can also use the dropper and squirt directly into the pet’s mouth. Some pets can be finicky, if this occurs consider hiding the drops in foods most pet’s love such as fish, chicken or yogurt or a favourite treat. If your pet only eats dry food then soak a few kibbles at feeding time.
For Best Results: Herbal dietary supplements are beneficial to the health and well-being of your pet and are safe for long-term use.

Cautions and Contraindications: Do not use Yucca in pregnant or nursing animals. Allowing breaks in feeding helps alleviate the possibility of a irritating effect on the digestive tract. Speak to your vet before using our products. A second visit is recommended if your pet’s condition does not improve, or deteriorates after continued use of the supplements.
