Filter

Steady flow, clean clearing — daily support for the gentle waterworks that keep a dog or cat bright.

Filter is built around one simple aim: keep the fluid that moves through your animal moving freely, and keep what the body sets aside to release moving cleanly out. Every day, a dog or cat takes in water, minerals, and the ordinary byproducts of a busy metabolism, and every day the body has to sort, balance, and pass them along. Filter is a four-herb hot-water extract — dandelion, goji, eucommia, and licorice — chosen to stand alongside that natural rhythm and help it run smoothly.

Reach for it when you want quiet, structural maintenance rather than a reaction to a crisis: the older cat you'd like to keep comfortable and steadily drinking, the dog whose water and mineral balance you want to keep even, the companion whose general brightness, coat, and easy movement you want to protect over the long arc of a life. This is a tonic in the oldest sense — something you give consistently so the body's own clearing pathways stay well-tended.

The blend leans on traditions that, across continents, all noticed the same thing. The Western herbalists Culpeper among them prized dandelion as a herb of free flow; the Greek-Galenic physicians kept their own gentle diuretic roots; classical Chinese practice treasured eucommia and goji as nourishing tonics for the deep reserve the body draws on for fluid balance and steady vigor; and the great compounding traditions of India and Africa each kept a 'harmonizer' — a herb like licorice whose role is to round the formula and carry it gently. Filter is those convergent insights, gathered into one cup.

It is a maintenance companion, not a rescue. Filter supports the normal structure and function of your animal's urinary and fluid-handling system; it is food-grade botanical nourishment, scaled to the animal in front of you and meant to be woven into ordinary daily feeding.

How it works

The science of Filter

Not buzzwords — the actual biology of the plants in this formula: their compounds, the targets those compounds are measured to engage, and the systems they nourish.

Each herb here carries well-characterized plant compounds, and they were chosen because their actions converge on the same outcome: smooth fluid handling and clean clearing. Dandelion contributes luteolin and taraxasterol; goji brings zeaxanthin, betaine, and kukoamine A; eucommia adds chlorogenic acid, aucubin, and pinoresinol diglucoside; licorice supplies glycyrrhizin, liquiritigenin, and glabridin. These are not exotic additives — they are the leaf, root, and berry constituents the plants make on their own.

Dandelion is the herb of free flow. In the herbal tradition it has always been the gentle 'pass-it-along' plant, encouraging the body to keep fluid and the ordinary minerals it carries in steady, easy movement rather than letting them sit and stagnate. Goji and eucommia are the deep nourishers: goji's betaine acts as a natural methyl donor and its carotenoids feed the tissues, while eucommia has been the classic kidney-and-structure tonic for centuries, supporting the reserve and resilience the fluid system relies on. Licorice is the harmonizer — soothing and demulcent, it softens the whole blend and helps the body receive the others as a single, cohesive food.

Filter is offered as structure-and-function support for the normal urinary and fluid-balance pathways of healthy companion animals. We describe what these plants nourish and how they have been used — food-grade botanical support, not a remedy for any condition. As with any concentrated botanical, licorice in particular means Filter is meant for measured daily use at the animal's scale, not heavy or unsupervised dosing.

In practice

Who it’s for, and how to use it

Who it’s for

For dogs and cats whose people want quiet, daily support for the urinary and fluid-handling system — especially older or steadily-drinking companions you'd like to keep bright, even, and comfortable over the long haul. A maintenance tonic for healthy animals, not a response to acute distress; if your animal is genuinely unwell or behaving unusually around drinking or passing water, that warrants a hands-on professional look, with Filter as ongoing background nourishment.

How to use it

Stir a small amount of the dilute hot-water extract or powder into food, scaled to your animal's body weight. Start low — a pinch for a cat or small dog, a little more for a large dog — and build gradually over several days so the body eases into it. Best given consistently as part of daily feeding rather than in occasional large doses; because licorice is concentrated, keep to the measured amount and let steadiness, not strength, do the work.

What’s inside

Filter is one of our simplest formulas, and that is on purpose. Four herbs, each with a clear job, each one a plant a careful herbalist anywhere in the world would have recognized: the one that keeps things flowing, the two that nourish the deep reserve, and the one that harmonizes the cup. We kept it small so it could be given every day for a lifetime — because the waterworks that quietly carry your companion through each day deserve quiet, faithful tending. Thank you for trusting us to help you keep that animal bright.

Structure-and-function support for animal nutrition and vitality. Introduce gradually and watch how your companion responds. Not intended to diagnose, treat, cure, or prevent any disease. If your animal is pregnant, nursing, or on medication, consult your veterinarian first.
