Clear Out the Bad Bacteria.

Keep the good.

The big-brand mouthwashes kill everything in your mouth — the good bacteria and the bad. The Halo Pulling Oil takes a gentler, older route: it physically pulls out the bacteria behind bleeding gums and bad breath, and leaves the ones your mouth needs alone.

No Alcohol, No Burn

Keeps Good Bacteria

60-Day Guarantee

It doesn't nuke your mouth.

Most mouthwash works by killing germs with alcohol or antiseptics — but it can’t tell good bacteria from bad, so it kills both. Your mouth needs the good ones to stay balanced. The Halo oil skips the killing and pulls the bad bacteria out instead.

Calmer gums, fresher breath.

In studies, people who oil pulled regularly had less gum bleeding and puffiness, and noticeably fresher breath — the things you feel first thing in the morning and notice up close.

Reaches where a rinse can't.

The bacteria that matter hide in the tight gaps where gums meet teeth. A watery rinse beads up and slides past — oil and water don’t mix. Oil does mix with the bacteria’s greasy coating, so it slips in, grabs them, and takes them with it when you spit.

THE PROBLEM

Most mouthwash kills the good with the bad.

---------------

First, the part nobody explains. Your mouth isn’t supposed to be germ-free. Like your gut, it runs on a balance of bacteria — the good ones keep the harmful ones in check and help keep your gums and breath healthy. That balance is the whole game.

Now look at how most mouthwash works. The big brands clean by killing bacteria — with alcohol, or with strong antiseptics. That’s the “kills 99.9% of germs” promise on the front of the bottle.

The catch is in that number. It doesn’t kill 99.9% of the bad bacteria. It kills nearly all of them — the good ones included. So you don’t fix the balance, you wipe it out.

And research backs this up. When people used a strong antiseptic rinse for two weeks, it changed the whole mix of bacteria in their mouths and even made their saliva more acidic.2 You’re not really cleaning your mouth — you’re carpet-bombing it, and then it has to recover.

There’s a second problem. A quick swish washes over the flat surfaces of your teeth, but the bacteria behind bleeding gums and bad breath don’t live there. They live in the tight gaps between your teeth and in the narrow line where your gums meet them — spots a rinse never really gets into. So the burn doesn’t even land where the trouble is.

So it was never about rinsing harder or longer. It’s about reaching the bad bacteria where they actually live, pulling them out, and leaving the good ones alone.

HOW IT WORKS

Penetrate · Bind · Extract.

---------------

First, what oil pulling even is: you take a small amount of oil, swish it around your mouth like a rinse, and spit it out. People have done it for thousands of years. It sounds almost too simple — until you see what the oil is actually doing in there. It happens in three steps.

Penetrate.

It reaches the spots a brush and a rinse miss.

The bacteria that cause the most trouble sit in the tight gaps between teeth and in the narrow line where gums meet teeth. A brush bristle can’t fit in there. And a watery mouthwash can’t help much either — oil and water don’t mix, so a watery rinse beads up and rolls past those gaps without going in. The Halo oil is pre-liquified to stay thin and runny, and because it’s an oil, it spreads into those tight spaces instead of sliding off.

Bind.

The bad bacteria stick to the oil.

After a few minutes of swishing, the oil is loaded with the bacteria it has pulled off your teeth and gumline. You spit it into the sink, and they go with it. Nothing is killed off with a chemical — the bad bacteria are simply lifted away and gone, a bit like a magnet lifting iron filings. Scientists have studied exactly this, and confirmed it’s a real, physical clean, not a placebo.⁸

Extract.

You spit it out — and they leave with it.

You spit. The bacteria leave with the oil. Physically removed from the crevice they have been living in, undisturbed, your entire life. Not suppressed by a chemical barrier that still leaves them below the surface. Not killed on the exterior while the source is protected. Removed. From the source. For the first time.⁶

THE KEY DIFFERENCE

How it clears the bad — without wiping out the good.

---------------

It comes down to one thing: stickiness.

The bacteria behind bleeding gums and bad breath have one habit that gives them away: they stick. They clump into a sticky film and glue themselves to your teeth and along your gumline. Your good bacteria don’t do this — they drift loose in your saliva, all through your mouth. So when you swish a thin oil, that sticky film clings to it — like flour to oily fingers — and you spit it out. The good bacteria, floating free, have nothing to grab onto. They stay right where they are.

A chemical mouthwash works the opposite way. It doesn’t grab anything — it kills. It floods through your mouth and kills bacteria on contact, the good kind right along with the bad.² That’s the catch with a rinse built to kill: it can’t take only the bad, because it isn’t taking anything at all. It’s just killing everything it touches.

🧪 Antiseptic Mouthwash

Floods your whole mouth at once

Kills on contact — good and bad alike

Never targets the actual buildup

Leaves the balance wiped out

🕊️ The Halo Pulling Oil

Flows into the gaps where the buildup hides

Lifts the harmful overgrowth out — you spit it away

No chemical flooding the rest of your mouth

Leaves your good bacteria and your balance intact

Flour rinses straight off under a tap, but clings to oily fingers. The harmful film works the same way — a rinse leaves it behind, and the oil takes it with it.

THE STUDIES

We’re not asking you to take our word for it.

Here’s the actual research on oil pulling — in plain English, with a link to each study so you can read it for yourself.

THE SHORT VERSION

In studies, oil pulling cleared the harmful bacteria about as well as a strong antiseptic mouthwash — and left people with calmer gums and fresher breath. The difference is how: it lifts the bad bacteria out (they stick to the oil and leave when you spit), instead of flooding your mouth with a chemical that kills the good ones too.

A Review of All the Studies · 2024

Healthier Gums, Across the Board.

Researchers gathered up the good oil-pulling trials and looked at them together. The takeaway: oil pulling left people with healthier gums and fewer of the bacteria behind the trouble, compared with normal brushing or rinsing.

WHAT'S INSIDE

The oils — and what each one does

No mystery “fragrance,” no blend you can’t read. These are the key oils in the bottle, and the plain reason each one’s there.

Oregano Oil

Title

The Heavy Hitter.

One of nature’s strongest germ-fighters. It breaks down the outer wall of the bad bacteria it touches, so they can’t hold on. ^{(study ref 7)}

Coconut Oil

Title

The Base.

The oil that does the lifting. It’s what the bad bacteria stick to, so they come away when you spit — and it’s gentle enough for every single morning. ^{(study ref 7)}

Manuka Oil

Title

The Oil, Not the Honey.

When several oils were tested side by side against the bacteria that harm gums, manuka oil came out the strongest of the bunch. ^{(study ref 8)}

Clove Oil

Title

The Soother.

A clean, minty note that freshens as you swish. Like everything here, it’s only ever swished and spat — never swallowed. ^{(study ref 7)}

Wintergreen Oil

Title

The Fresh Finish.

That cool, clean feeling after you spit. It freshens breath and helps make it harder for bacteria to settle straight back in. ^{(study ref 7)}

Peppermint Oil

Title

The Cool-Down.

That cool, clean feeling after you spit. It freshens breath and helps make it harder for bacteria to settle straight back in.^{(study ref 7)}

WHAT TO EXPECT

How to use it — and when you’ll notice.

---------------

We’d rather be straight with you than promise overnight magic. The routine is light, and here’s the kind of timeline the research suggests.

🥄 The Halo routine: twice a week, 7 minutes a session.

🌱 Week 1–2

The first thing most people notice is a fresher, cleaner-feeling mouth — often within the first session or two. Some notice it right away, some take longer. Both are completely normal.

⭐️ Week 2–4

Studies tracking oil pulling saw gums calm down — less puffy, less bleeding — within a few weeks of regular use. Keeping to your two sessions a week is what gets you there.

🕊️ Month 1 & On

In a month-long study, results kept improving through week four. After that it’s upkeep: bacteria build back if you stop, so it’s the steady habit that matters — not longer or harder sessions.

Holy Means Whole.

That includes the good bacteria your mouth was built to keep. Clear out the bad. Leave the rest alone.
