Step 01
Sourced by plant part
Each botanical is specified by its Latin name and the exact part used — cleavers aerial parts, red clover flower, stillingia root and prickly ash bark — so what goes in matches the label and traditional references.
Our story
Named for a humble hedgerow herb.
Cleavera exists to make a traditional four-herb formula easy to take, honest about what’s inside and completely alcohol-free. This is the story behind the name, the things we care about and how every bottle is made and checked.
Where the name comes from
From cleavers, the herb that clings
Walk along almost any hedgerow in spring and you’ll find cleavers — a tangle of slender stems scrambling up through brambles and nettles, catching on everything it touches.
The name comes from the old sense of the word “cleave”: to cling or stick fast. Country names like goosegrass, catchweed and sticky willy tell the same story. Most gardeners pull it out without a second thought, yet cleavers has been part of herbal tradition for centuries, and it sits at the heart of our formula.
We liked the idea of naming a brand after something humble, useful and hiding in plain sight. Look closely at a stem and you’ll see its narrow leaves growing in neat rings, or whorls, around it — usually six to eight at a time. The six-petal mark in our logo is drawn from that pattern: a simple ring of leaves around a center point.
Our mission
Make a traditional herbal formula easy, honest and alcohol-free
Herbal traditions are full of good ideas that are hard to live with day to day — strong tinctures, vague labels, complicated routines. We set out to keep the tradition and lose the friction.
Easy
One mL, twice a day, in whatever you’re already drinking. No capsules to swallow and no complicated protocol — just a small daily ritual, explained step by step on our how it works page.
Honest
Every botanical is named on the label with its Latin name and plant part. We use careful, traditional language, put an asterisk where one belongs and never publish invented reviews, ratings or statistics.
Alcohol-free
Most herbal tinctures are made with alcohol. Ours are extracted in vegetable glycerin and water instead, so the drops are mild and naturally sweet. Read glycerite vs tincture to see why.
The formula
Four plants with a long shared history
Cleavers, red clover, stillingia and prickly ash each have a long record in 19th-century American herbal practice, and herbalists have often combined them.
We didn’t try to reinvent that combination. We kept the four herbs, named the exact part of each plant — cleavers aerial parts, red clover flower, stillingia root and prickly ash bark — and changed only what made the tradition hard to live with: the alcohol. The result is a 300 mg proprietary blend in every 1 mL serving, with just two other ingredients, vegetable glycerin and water.
Together, these botanicals are traditionally used to support healthy lymphatic flow and circulation.* You can read each plant’s history and safety notes on our ingredients page.
What we value
Six things we won’t compromise on
Each one is something you can check for yourself — on the label, in your cart or in your account.
Honest labels
Plain, accurate language on every box and page. Traditional-use statements carry an asterisk and the FDA disclaimer, always.
Alcohol-free
Extracted in vegetable glycerin and water, not ethanol. Gentle enough to take straight, easy to stir into any drink.
Third-party tested
The finished formula is tested by an independent laboratory for quality and purity before it reaches you.
Plant-part transparency
Aerial parts, flower, root and bark — named on the label for every herb, because the part of a plant changes the character of an extract.
Customer-first subscriptions
Optional, never pre-selected: 25% off and free shipping, a reminder email before every renewal, and skip, pause or cancel online in one click. No phone calls and no hoops to jump through.
Amber glass, on purpose
We chose amber glass over plastic. It helps shield the extract from light and is accepted by many recycling programs — check yours, and remove the dropper first.
Quality
How Cleavera is made & checked
We’d rather explain our process plainly than cover the box in badges. Here’s what happens between the plant and your bottle.
It starts with naming things precisely: the right plant, the right part, the right extraction. It ends with an outside lab and a final check against the label. In between, nothing is added that you can’t read on the Supplement Facts panel.

Step 02
Glycerin + water extraction
The herbs are extracted in vegetable glycerin and water rather than alcohol, producing a mild, naturally sweet liquid with a 300 mg proprietary blend in every 1 mL serving.
Step 03
Third-party testing
The finished formula is tested by an independent, third-party laboratory for quality and purity before it is released for sale.
Step 04
Finished-product checks
Finished bottles are checked against the label before they ship, so the product in your hands matches the Supplement Facts panel on the box.

Editorial standards
How we write the Journal
Every article in the Cleavera Journal is written by the Cleavera Editorial Team, the same small team that makes the drops. Here’s how we work.
- Sourced, not guessed. We research each topic in reputable sources such as the NIH (including NCCIH, the Office of Dietary Supplements and MedlinePlus), the CDC, Cleveland Clinic, peer-reviewed studies and university extension services. Every article lists its sources at the end.
- Honest about evidence. When research is limited, we say so plainly. We describe how herbs have been used traditionally and never present tradition as proof.
- Within the rules for supplements. We follow FDA and FTC guidance: structure/function language only, marked with an asterisk, and no disease claims.
- No invented voices. No paid or made-up reviews, testimonials, experts or statistics.
- Not medical advice. Our articles are general education. Talk to your healthcare professional about your own health, especially if you’re pregnant, nursing, taking medication or managing a health condition.
- Kept current. Each article shows when it was published, and we update articles when guidance changes. Spot an error? Email hello@cleavera.com and we’ll review it.
