Thousands Report This 1900s Mullein Remedy Is a "Miracle" For Thick Phlegm In The Chest And Sinuses — 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
And they're all saying one of two things. "It got worse after COVID" or "this all came after my first COVID diagnosis."
Why COVID Creates Severe Phlegm Problems
Shocking new research reveals COVID had 3 distinct ways to target and destroy the lung's natural mucus-clearing system.
The lung's natural clearing system is one of the most important — if not the most important — mechanisms that your lung has.
Thousands of tiny, microscopic hairs — called cilia — sweep up mucus in a rhythmic motion to clear heavy phlegm from your body.
It's lined all over the airways, all the way from the sinuses to the deepest part of your lungs.
The rhythm is the main part. It lets the relatively weak cilia work in sync to clear out even the heaviest of phlegm.
When it's working correctly, most people find they have zero mucus issues.
But COVID had 3 ways to attack this very system.
Firstly, researchers found it produced a protein called ORF10.
ORF10 directly shreds and destroys the tiny cilia scattered all over the lungs.
Without the hairs, there is nothing to clear out the mucus.
The phlegm backs up in the system. It's why you feel that heavy chest. It's why you feel the need to manually spit and clear mucus.
The mucus doesn't clear anymore. It just sits there. It hardens. It becomes a weight in your chest.
But that's not all.
At the same time, a 2021 study published in Nature Communications found COVID hijacks the FOXJ1 pathway.
The FOXJ1 pathway is the cilia's master cell. Whenever a cilia naturally dies or breaks, this cell allows the cilia to grow back as a tiny-hair.
COVID switches this cell off.
As a result the tiny-hairs don't grow back properly. And when they do grow back, they're misaligned. Off-rhythm. Out of sync.
They no longer work effectively together. They struggle to clear out heavy phlegm.
It's a devastating combination.
The virus shreds the hairs and at the same time shuts off the way for the hairs to grow back and heal.
This damage can remain for years. This is not something that "just recovers on its own."
Researchers at the University of Dundee found signs of this ciliary dysfunction still present up to 12 months after infection — in the large majority of people they studied.
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.
The "Forgotten Remedy" That Clears Out The Thick Mucus
There's one remedy that is repeatedly mentioned in treating these very problems. A non-assuming plant used extensively in the 19th and 20th century.
In 1918, contrary to popular belief, the Spanish Flu was not much of a problem. But the phlegm issues that came afterwards were devastating.
Patients often repeated very similar things: the same throat clearing, the same sleeping issues, the same heavy chest.
During this period, doctors relied on mullein leaf to clear out stubborn phlegm deep in the airways.
But not just any mullein leaf. It was a specific remedy that 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 with mullein compounds by the day. 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.
This 1900s mullein formula is being rediscovered by post-COVID sufferers today. They're reporting exactly the same effects.
The Research Behind Mullein — What Is The Scientific Basis?
During the research, we noticed something strange.
When looking at people who actually tried mullein for post-COVID mucus, there were two groups:
Group 1 swears by mullein and calls it a 'miracle herb'. Saying it completely solved their mucus problems. But group 2 says that it's just another supplement that fails to deliver.
We decided to investigate these claims. To find out whether they're real. Whether mullein can actually clear out the mucus. What doctors are saying about it. Analysing the studies.
What we found genuinely shocked us.
Mullein is rich in specific compounds called saponins.
How these microscopic plant compounds work is nothing short of remarkable.
They have a special relationship with the vagus nerve — the primary communication pathway in the human body.
When saponins are digested, they gently react with the gut-lining in the stomach which triggers a 'vagal reflex.'
This stimulates the vagus nerve to where it releases watery fluids all throughout the airways.
This is not an exaggeration. All throughout the airways fresh watery secretions leak out of the airways and penetrate the thick phlegm.
The phlegm softens. It loosens. It becomes effortless to clear.
Your cilia can start moving it again. All that hardened phlegm now becomes diluted. It lightens.
You can finally cough it up.
Doctors call it the gastro-pulmonary reflex.
Saponins react with gut-lining
The saponins react with the stomach lining.
Triggers a vagal reflex
That reaction stimulates the vagus nerve.
Vagus nerve releases watery secretions deep in the airway
The vagus nerve signals the tiny glands lining your airways to release thin, watery fluid.
Watery secretions dilute the phlegm
That fluid dilutes the phlegm that's been building up in the airways, making it easier to cough up.
This is how mullein has worked for all of these years.
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 same exact mechanism was clinically studied in Ivy Leaf — another herb known for its high bioavailability of saponins.
In one placebo-controlled trial published in Nature's Scientific Reports, people taking a saponin-rich expectorant were more than twice as likely to completely stop throat-clearing.
In fact, these natural saponin expectorants have clinical research spanning over 100,000 patients and are regularly prescribed by doctors throughout Europe.
And what's even more remarkable is your cilia get to heal and finally have a chance to recover from the damage COVID caused.
Without the hardened phlegm sitting in your airways, your natural clearing system can return to normal.
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 are studied and known across an array of clinical studies and built upon hundreds of years in traditional use.
When people actually try what the 1900s doctors prescribed, they finally unlock mullein's power in its true form.
CleraVox Mullein Super Strength is bringing it back. A strong, concentrated mullein extract made with authentic, real mullein.
It's brown just like it how it was traditionally. It's concentrated — filled with saponins and mullein's natural compounds so you can finally recover from COVID's damage on your lung system.
3,500mg. It's powerful, and not watered down.
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 get all the benefits of mullein in a gentle format 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.
In this special bulletin you'll see the other remarkable compounds in mullein that address the damage from COVID so you can truly recover again.
Please read on to see why thousands 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 condition 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 almost four 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 concentrated 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 deep in the airway tissue. These fragments can remain for years.
When your immune system comes across these hidden fragments, it panics and puts your body into a state of inflammation. Your body can't tell that the virus is gone.
As a result, your body produces more sticky proteins in the mucus. It's a defence response — designed to trap any microbes before they get deeper into the lungs.
Your body pours even 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 corticosteroid asthma drugs act on.
As a result, your body produces mucus with fewer sticky proteins. Your mucus production returns to a much healthier, thinner state.
Social Confidence Returns
Many people that try mullein don't expect this next benefit. But it's welcome nonetheless.
Sufferers had no idea what the phlegm did to their personality. They got used to it.
Years of hiding the spitting.
Years of staying silent.
Years of not trying to offend anyone.
Years of avoiding embarrassment.
It made them dull.
When they finally clear out all the mucus? When they finally get a chance to recover from the damage COVID caused?
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 watching other people's faces to see if they're irritated with 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 a bottle of CleraVox with them.
It gives them a feeling of safety. Just having the concentrated extract within arm's reach.
How To Take CleraVox
When you first receive your CleraVox bottles this is the protocol we usually recommend for those just starting:
Take two droppers before you go to bed every night. This lets the mullein compounds work in your system overnight while you sleep.
It makes it easier to clear out the mucus in the morning. It's lighter, softer, easier to bring up.
Then after most of the stagnant phlegm in the chest clears out, 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 that thins the mucus.
Your Body Makes More Watery Secretions
Mullein's saponins begin absorbing into your system over time.
They prompt your body to increase watery secretions in your airways — 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.
