Thousands Are Reporting "Miracle Remedy" For post-COVID Phlegm. "The Only Thing That Actually Worked." — We Decided To Investigate
If you're dealing with constant thick phlegm, sinus issues, or trouble bringing up stuck mucus…
You're not alone.
Thousands of adults over 55 are dealing with the exact same thing:
Throat Clearing
Flat At Night
Sinus Problems
Expelling Mucus
How COVID Created Severe Phlegm Problems
Shocking new research reveals how the COVID virus actually worked, it attacked our lung's natural mucus-clearing system.
The lung's mucus-clearing system is one of the most integral parts of our health.
Without it, there would be stuck phlegm in our airways daily. It would be hard to breathe, hard to lie down flat at night, you'd feel the need to clear your throat constantly, etc.
This is how it works:
Millions of tiny hairs constantly clear out mucus.
They sweep up phlegm constantly. They're microscopic. And they're everywhere in your airways, from the sinuses all the way to the lungs.
They keep your airways clear from mucus.
Scientists call these hairs "cilia" — also known as your lung's mucus-clearing system.
Without functioning cilia, phlegm quickly begins to build-up.
If you want clear lungs. If you want all the stuck phlegm cleared. Your cilia must be healthy. That's the bottom line.
Unfortunately, COVID had 3 ways to attack this very system. And it has had devastating effects.
Firstly, researchers found the virus produced a protein called ORF10.
ORF10 is designed to directly destroy the cilia. Shredding the hairs from the root.
Without the hairs, there is nothing to clear out the mucus.
The phlegm backs up in the airways. Layer after layer, the mucus piles up.
There aren't any hairs to sweep it all out. So it just sits there. It starts to harden.
It's why you feel that heavy weight in your chest. It's why you have to manually spit the mucus out. Manually cough it up yourself. Your hairs can't do it for you anymore.
But that's not all.
At the same time, a 2021 study published in Nature Communications showed COVID stops the cilia from healing.
Cilia die all the time. It's natural. They can grow back easily. But COVID switches off the cells that allow cilia heal.
As a result, the cilia don't grow back properly. And when they do grow back, they're misaligned. Off-rhythm. Out of sync.
They no longer work effectively. They struggle to clear out the heavy phlegm.
It's a devastating combination.
The virus shreds the tiny-hairs. Then, at the same time, it shuts off the way for them to heal.
This damage can remain for years. This is not something that "just recovers on its own."
Researchers at the University of Dundee documented this. They found signs of ciliary dysfunction (broken cilia) up to 12 months after COVID.
12 months. 12 months of broken cilia.
This is why so many people have phlegm problems even years after COVID.
The worst part is they have no idea. They walk around with a broken mucus-clearing system for years. Never connecting the dots that it was from COVID.
Even people who never felt the virus during the pandemic. Research shows they can still have damaged cilia, and not even know.
That's why it's so devastating.
The "Forgotten Remedy" That Clears Out The Stuck Phlegm
But here's what most people do not know.
We saw very similar things happen during the 1918 Spanish Flu.
You see, contrary to popular belief, the Spanish Flu was not a big problem in and of itself. But the phlegm problems that came afterwards? They were disastrous.
The same throat clearing, the same sleeping issues, the same heavy chest. Constantly being reported.
And all of them showing up only after the virus.
The 1900s doctors didn't know why this was happening. No idea what cilia even were, they lacked the technology.
But here's what they did know:
They knew how to clear the stuck phlegm. Fast.
There was a specific mullein remedy that doctors at the time used.
Not just any simple mullein remedy. This one took days to make.
They would ground down dried mullein leaf. Soak it in a strong alcohol solution. And let it soak for days on end. You could see it get more concentrated by the day. The mullein compounds absorbed into it.
It became a deeper and deeper brown colour.
When doctors prescribed it, patients reported that the mucus itself became thinner.
It became easier to bring up and cough out. There was no more wheezing in the lungs. Their chests became lighter. Like a weight was lifted.
And now, this 1900s mullein remedy is being rediscovered today. By those dealing with post-COVID mucus.
Remarkably, they're reporting exactly the same effects. They're saying it actually works.
The Research Behind Mullein — What Is The Scientific Basis?
But, when looking at the mullein reports, we saw something strange.
Those that tried mullein usually fell into 2 groups.
Group 1 swears by mullein and calls it a 'miracle herb'. Saying it completely solved their mucus problems. But group 2 calls it "just another supplement." Saying it fails to deliver.
We decided to investigate these claims, to find out who's telling the truth.
Looking deep into the research. What doctors are saying. What the clinical studies show. Whether mullein has any backing behind it.
What we found genuinely shocked us.
The leaves of mullein are rich in a specific compound, they're called saponins.
Remember this name: saponins.
Because these tiny-little plant compounds work in a remarkable way.
Now we have to warn you.
When people hear how saponins work for the first time, they all usually have the same reaction. Shock. Disbelief. But bear with us for a few moments.
Research shows, when saponins are digested in a large enough amount, they cause a reaction in the stomach.
The saponins trigger a reflex that makes your airways release watery fluids.
Doctors call it the gastro-pulmonary reflex.
For some reason, that scientists cannot explain yet, saponins trigger this strange reflex.
The reflex makes your body give out orders: "release watery fluids throughout the airways."
This isn't fantasy. All throughout the airways fluids secrete from the walls.
And this has a remarkable effect on the stuck phlegm.
These watery fluids are basically just some salt and water.
And this water penetrates the backed-up mucus. The mucus soaks in it. Absorbs it.
The phlegm softens. It breaks apart. It becomes effortless to clear.
Incredibly, your cilia can start moving it again. All that hardened phlegm now becomes diluted. It lightens. The hairs can start pushing it out again.
From the top of the lungs all the way to the bottom, this reaction happens.
Finally, you start to feel you can cough the mucus up. You can bring it up and expel it. You don't need to aggressively hack or strain your chest.
This sounds like hogwash. Like we made it up out of thin air.
But this is how mullein has worked all these years.
Researchers can't explain why this gastro-pulmonary reflex occurs. It requires more research. But we do know that it's real.
Mucinex — the #1 doctor-recommended expectorant in America — is actually based on this exact same mechanism.
It's designed to trigger the same gastro-pulmonary reflex.
But mullein does it without the harsh side effects, and brings a whole array of extra benefits you'll see in a moment.
Also this exact mechanism was clinically studied in Ivy Leaf — another herb known for its rich saponin content. Like mullein.
According to a placebo-controlled trial published in Scientific Reports, people digesting saponins in high doses, were more than twice as likely to stop coughing completely.
In fact, these natural saponin expectorants have clinical research spanning over 100,000 patients and are regularly prescribed by doctors throughout Europe.
Saponins react with the gut-lining
The saponins cause a gentle reaction with the stomach lining.
Initiates the gastro-pulmonary reflex
Your body sends out signals all over the airways: "release watery fluids"
Watery secretions dilute the phlegm
Watery secretions slowly start to seep out the airway walls. It dilutes the phlegm. You can finally clear it.
And here's what's even more remarkable: your cilia get to recover.
That hardened phlegm is sitting directly on top of your cilia. Pinning them down. Far too heavy for damaged hairs to shift.
Once it dilutes and starts moving, that weight comes off them. Probably for the first time in years.
It promotes an environment where everything can heal.
The Best Form of Mullein To Take
But this still doesn't answer our question. Why do so many people find that mullein is a miracle herb, yet others don't have the same experience?
We found the answer. And it didn't take us long. Over the internet and Amazon, mullein is flooded with weak supplements that barely do a thing.
- Weak mullein gummies
- Small mullein capsules
- Diluted mullein tea
- Under-dosed extracts
People try these. Feel nothing. Then say mullein doesn't work. But mullein does work. Its properties have been proven across countless clinical studies. And it has been used traditionally for hundreds of years.
Only when people take what the original 1900s doctors prescribed, they finally unlock mullein's power in its true form.
Remember: the doctors prescribed a real potent tincture. It was left to concentrate for hours on end. To let the compounds release from the leaf. It became a deep brown color.
CleraVox Mullein Super Strength is bringing it back. They saw all the weak mullein formulas everywhere and decided to do something about it.
A strong, concentrated mullein extract made with authentic, real mullein.
It's a deep brown color, just like it how it was traditionally.
It's concentrated — rich in saponins and mullein's natural compounds. It lets you finally combat the damage COVID caused. Finally giving your cilia a chance again.
3,500mg of mullein in every serving. That's powerful, nothing like the watered-down stuff you see today. This extract is actually filled with real mullein compounds.
Alcohol-free. This is the one thing the 1900s doctors couldn't do. They needed strong alcohol to create their tinctures.
CleraVox uses a modern extraction method, so you can take mullein without the harsh alcohol. It's designed to be a gentle mucus support that you can take daily.
Here's What People With Post-COVID Mucus Are Saying
Since COVID, my lungs felt so full it was like drowning when I lay flat in bed.
Swallowing was a problem all the time, which gave me a persistent cough. The mucus was so thick that bits of food would get stuck in my throat.
I saw the doctor. He didn't prescribe anything. So I sent for some CleraVox Mullein.
To my surprise, it helped almost immediately. After about a week I could breathe more easily and control the cough better.
As time went on, I could feel my lungs emptying, allowing me to take deeper breaths. It really does what it says. Great stuff.
After I got COVID 9 months ago, I started having severe mucus problems. I would cough so hard I'd throw up.
The mullein extract has loosened the mucus and significantly improved my quality of life.
My throat felt as if there was a mass I couldn't move, no matter how hard I tried. I was forever apologising when I tried to cough it up.
Since taking it, there's been a massive difference. It hasn't completely gone, but I rarely cough anything up now — and when I do, it's a small piece and much softer than before.
I'm a sceptic, I see all these remedies, but this is the real deal.
How To Take CleraVox
When you first receive your CleraVox bottles, this is the protocol we usually recommend for mullein beginners:
Take two droppers before you go to bed every night. This lets the mullein compounds work in your system overnight, while you sleep.
When you wake up the mucus should be easier to clear out. It's softer, more watery, easier to bring up.
Then after bulk of the chest phlegm clears, we recommend taking a maintenance dose of 2 droppers daily.
Swallow Two Droppers
Squeeze 2 full droppers of CleraVox into your mouth and swallow.
You can take it straight, or with a little water — whatever's easiest for you.
Once it's down, the mullein compounds get to work through your stomach, kicking off the gastro-pulmonary reflex.
Your Body Makes More Watery Secretions
Over time, mullein's saponins begin absorbing into your system.
They prompt your airways to increase watery secretions — which loosens and thins the thick mucus, so it can finally start moving and clear.
The Mucus Clears — And The Throat Calms
With the mucus thinned, your body can finally move it — bringing up the old phlegm that was stuck before.
From there, your body can finally expel the loosened phlegm — clearing it up and out of the chest and throat. So, the constant throat-clearing eases, breathing feels easier, and your nights get quieter.
In this special bulletin, you'll now see the other compounds that mullein contains. Saponins are just the beginning. Mullein contains many different compounds that also address COVID's damage. So you can truly have a healthy mucus system again.
Please read on to see why thousands of users daily regard mullein as a "miracle" herb. And how it's dramatically changing lives across the world.
Anti-Bacterial & Anti-Viral Properties
Doctors warn: the stagnant mucus creates a "breeding ground for bacteria" in the airways.
Think about it. The phlegm is warm, wet, and not moving. It creates the perfect conditions for bacteria to multiply.
These are the common microbes that thrive in the phlegm sitting in the lungs:
It's why so many sufferers of post-COVID mucus don't just report mucus in the chest, but in the nasal passages too.
They can often get sinus and chest infections from the billions of microbes living in the mucus.
In fact, a 2025 study tracked COVID patients for three years and found they kept coming down with recurrent infections.
Mullein directly inhibits this.
The leaves of mullein are rich in a compound known as verbascoside.
It helps stop microbes taking hold in the body. Early lab studies show it acts against viruses including: Influenza A, HSV-1/HSV-II, HBV, and HCoV-229E — a human coronavirus.
It's why so many people with chronic sinus issues report getting them less often after taking mullein consistently. They feel healthier as a result — fewer colds, and more resilience against illness.
CleraVox's extraction method preserves these exact verbascoside compounds. Their extract is filled with it.
I just want to say that this stuff is a miracle! I shouldn't be surprised that God would make just what we need to get better on His good earth.
I have been suffering with extreme sinus issues for years which got worse after COVID. I was hardly getting any sleep and constantly getting colds and sinus infections.
Now I hardly need to use nasal sprays. It took a month to get results, like you say. I just ran out of my second bottle, so I ordered three more. I don't ever want to run out!
Anti-Inflammatory Properties
And that's not where the benefits of verbascoside end. New research shows that COVID keeps the body in a chronically inflamed state.
A 2023 study showed that COVID leaves behind tiny fragments of itself. They lay deep in the airway tissue, and can remain there for years after the virus has already left. Completely hidden.
When your immune system finds these hidden fragments, it panics. It puts your body into a state of inflammation. Your body can't tell that the virus is gone. It still thinks it's under attack.
Here's why this is an issue: when you're inflamed, your body produces thicker mucus. It's a defence response — designed to trap any microbes before they get deeper into the lungs.
But the defence response is over a false alarm. It's not needed, it's only harmless fragments.
Your body ends up pouring MORE thick mucus into an already backed-up system.
The University of Naples showed that verbascoside reduces inflammation in the lungs directly.
It significantly reduces iNOS — the same inflammatory enzyme that anti-inflammatory asthma drugs act on.
As a result, your body produces mucus that is less thick. Your mucus production returns to a much healthier, thinner state.
Social Confidence Returns
This next benefit is unexpected. But mullein users welcome it warmly nonetheless.
When you have chronically thick phlegm, you can forget what it does to your personality. You get used to it.
Years of hiding the spitting.
Years of staying silent.
Years of not trying to offend anyone.
Years of avoiding embarrassment.
It makes you dull.
When you finally clear out all the mucus? When you finally get a chance to recover from COVID?
You become someone entirely different.
You become lively again. The dullness leaves. You're in a better mood constantly. You're finally resting at night.
It just makes you have a stronger vitality for life. You stop worrying what others think of you. You stop worrying if anyone is glancing at you.
You can just relax again.
We've received the feedback ourselves. Spouses that're emotional over their husband's transformation, asking for more bottles of CleraVox.
They refuse to go anywhere without it now. Any long trips or vacations, they always make sure to bring CleraVox with them.
It gives them a feeling of safety. Just having the concentrated extract within arm's reach.
