What is Thuja
When it comes to natural wellness for dogs, Thuja is one of those little-known remedies that deserves more attention.
Whether your pup is struggling with skin tags, odd warts, or showing signs of a vaccine reaction, Thuja occidentalis may be worth a second look. I’ve seen it make a real difference, especially when used at the right time and in the right combination with other natural supports.
Let’s walk through how Thuja works, why I include it in many post-vaccine protocols, and when it might be the right remedy for your dog.
What Is Thuja?
Thuja (pronounced thoo-yuh) is a homeopathic remedy made from the Eastern Arborvitae tree. In its herbal form, Thuja has long been associated with detox, skin support, and immune health. But in homeopathy, it’s used in a diluted, energetic form to address deep-seated symptoms that show up physically—especially through the skin.
In dogs, it’s most commonly used for:
Warts
Skin tags
Growths that appeared after vaccination
Chronic ear or skin conditions that don’t resolve
Sensitivities to touch, grooming, or handling
Thuja is considered a constitutional remedy for many dogs—especially those who are sensitive to toxins or have a history of vaccine reactions.
Thuja as Part of a Vaccine Detox Protocol
I frequently include Thuja in post-vaccination care for dogs—especially when we're trying to minimize or manage potential vaccine reactions, known as vaccinosis.
Here’s how I typically use it:
Before, during, and after vaccine appointments (especially combo vaccines)
Paired with Silicea, another homeopathic remedy that supports the body’s ability to push out what doesn’t belong
Added to broader detox protocols for dogs showing symptoms like skin issues, behavioral shifts, digestive problems, or general regression after a shot
And when the rabies vaccine is involved?
I always recommend adding Lyssin to the mix as well. Lyssin is specific to the rabies nosode and addresses emotional or neurological changes that may follow that particular vaccine.
Why Use Thuja Around Vaccines?
Vaccines do more than deliver immunity—they stimulate the immune system, and in some dogs, this causes overstimulation or imbalances in other systems (like skin, digestion, or behavior).
Thuja doesn’t cancel out the vaccine—it helps the body process it more efficiently, reducing the risk of lingering side effects.
If you're using a ready-made product like Adored Beast’s Rebalancer, you’re already giving both Silicea and Thuja—an excellent combo for dogs and even people following vaccines.
I prefer to give Thuja:
The day before vaccination
The day of vaccination
The day after vaccination
But if your dog has already shown signs of a reaction, we may need to look at additional layers of support—including Lyssin, detox herbs, essential oils, or gut-focused protocols.
The Truth About Vaccine Injury and Vet Pushback
If you bring up the idea of vaccine injury or detox at a conventional veterinary office, you’ll likely be dismissed.
But I’ve seen it time and time again—dogs who changed dramatically after a round of shots, especially if multiple vaccines were given together.
The science on this is still catching up, and studies are hard to fund (thanks, Big Pharma), but the case studies speak volumes.
So if your gut says something changed in your dog after a vaccine… you’re probably right.
Using Thuja for Skin Tags and Warts
Beyond vaccines, Thuja is also a go-to for odd skin growths, especially those that:
Are soft, lumpy, or cauliflower-like
Bleed or crust over
Have been slow to shrink or disappear
In these cases, Thuja may be used internally (as a homeopathic remedy) or topically (as a wet remedy or tincture). I can guide you on the best approach based on your dog’s specific needs.
If you’ve tried topical sprays and nothing’s worked—or if your vet says it’s “just cosmetic”—this may be worth a try.
