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:

And they're all saying one of two things. Either all of this came after COVID. Or these symptoms became more severe after COVID.

Why COVID Creates Severe Phlegm Problems

New research shows that the Coronavirus variant we saw in the last few years contains multiple mechanisms that impair our lungs' natural clearing process. And in older adults with already-weakened immune systems, the results have been devastating.

The ORF10 protein the virus produced specifically targeted lung-cell production. The virus directly shredded the lung's microscopic cleaners that sweep up mucus.

So instead of mucus naturally clearing out and coming up to the throat, it now stays trapped deep in the chest. It causes breathing issues, a heavy chest, sinus infections, and trouble lying flat at night.

Doctors say it creates a "breeding ground of bacteria." Because mucus that doesn't move creates the perfect conditions for bacteria to multiply. Think about it. It's warm, wet, and not moving.

It's why so many sufferers of post-COVID mucus don't just report mucus issues in the chest, but also in the nasal passages. They often get sinus infections and colds from the billions of microbes in the mucus.

Mucus becomes thick and concentrated in the chest. Your body keeps producing more on top of it. Layer after layer. Doctors say it's dangerous and should be cleared as soon as possible.

The "Forgotten Remedy" That Clears Out The Thick Mucus

Mullein plant with yellow flowers

There's one remedy that is repeatedly mentioned in treating these very problems. Effectively, at that. It is a non-assuming plant, used extensively in the 19th and 20th century.

During the 1918 Spanish Flu, doctors saw the exact same problem. Contrary to popular belief, the fever itself was mostly harmless, most patients recovered fine. But the phlegm problems directly after? It was another story.

Patients often repeated very similar things to what we see today with post-COVID mucus. 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.

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.

The Research Behind Mullein -- What Is The Scientific Basis?

The science behind how mullein clears mucus

During the research, we noticed something strange.

When seeing any discussion about the plant there's usually 2 groups. Group 1 swears by mullein and refer to it as a genuine miracle plant. But group 2 says that it doesn't work, and its just another supplement that fails.

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 .

What we found genuinely shocked us.

Mullein is rich in specific compounds called saponins. The way 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.

Magnified active compounds of mullein

When saponins are digested in the stomach, they gently react with the stomach lining. This triggers a vagal reflex that signals your airways to release watery secretions. This fresh watery secretions penetrate the thick, stagnant mucus and makes it thin again. Easy to cough up again.

Doctors call it the gastro-pulmonary reflex.

1
Saponins entering the stomach

Saponins react with gut-lining

The saponins react with the stomach lining.

2
Vagal reflex triggered

Triggers a vagal reflex

That reaction stimulates the vagus nerve.

3
Signal travelling up 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.

4
Watery fluid thinning the thick mucus

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. This same exact mechanism was clinically studied in Ivy Leaf-- another herb known for its high bioavailability of saponins.

Mucinex is actually based on this same mechanism. It's swallowed and stimulates the vagal nerves in the stomach lining. It causes the bronchial glands to add more watery fluid. Only mullein does not come with the harsh side effects and has a tremendous array of additional benefits.

In fact, the most-studied natural saponin expectorant has clinical research spanning over 100,000 patients and is prescribed by doctors across Europe. Mullein belongs to that same family of saponin-rich respiratory herbs. Saponins are a clinically-studied class of natural expectorants that often perform much better than their lab counterparts.

It becomes clear why so many post-COVID mucus sufferers are finding relief. It directly goes against the damage COVID caused. The damaged lung system can finally manage the phlegm. It's thin again. Loose again. It can be brought up effortlessly.

Cilia recovering as mucus thins

And what's even more remarkable is that the lung's mechanisms finally get room to recover from COVID's damage. Without the disruptive phlegm sitting on top of it, the damaged cells have room to recover. When you take mullein long enough, your natural clearing can slowly go back to normal.

Mullein is actually officially recognised by the European Medicines Agency (Europe's version of the FDA) for traditional use as an expectorant.

The Best Form of Mullein To Take

Weak mullein forms - gummies, tea and capsules - crossed out

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 Europe.

But when people try what the 1900s doctors prescribed, they finally see mullein as the powerful plant it truly is. They just need to return to what the 1900s doctors actually prescribed their patients.

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 mullein is considered a "miracle" herb, changing thousands of lives daily.

Anti-Bacterial & Anti-Viral Properties

Mullein helps directly to inhibit the bacteria that thrive in stagnant mucus:

Streptococcus pneumoniae
Streptococcus pneumoniae
A common cause of bacterial pneumonia.
Haemophilus influenzae
Haemophilus influenzae
Linked to chest-infection flare-ups.
Moraxella catarrhalis
Moraxella catarrhalis
Associated with airway inflammation.
Pseudomonas aeruginosa
Pseudomonas aeruginosa
Known to thrive in stagnant mucus.
Staphylococcus aureus
Staphylococcus aureus
A common respiratory-tract bacteria.
Klebsiella pneumoniae
Klebsiella pneumoniae
Another cause of chest infections.

The leaves of mullein are rich in a compound known as verbascoside. And it directly stops bacteria from taking hold. Research also shows it inhibits against viruses: Influenza A, HSV-1/HSV-II, HBV, and HCoV-229E, a human coronavirus.

It's why so many people with chronic sinus infections report getting them less often after taking mullein consistently. They feel much healthier as a result, getting less colds and having more immunity to illnesses.

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.

Studies show that COVID keeps the body in a chronically inflamed state. A 2023 study showed that COVID leaves behind tiny fragments deep in the airway tissue. These fragments can remain for years.

Chronic airway inflammation illustration (placeholder)

When your immune system comes across these fragments it goes into panic mode and turns on your body's inflammation response. Making your body add sticky protein to your mucus. That sticky protein makes the mucus thick to trap any viruses from going deeper into the lungs.

Verbascoside has data from the University of Naples showing that it reduces inflammation in the lungs directly. Verbascoside significantly reduces iNOS — the same inflammatory enzyme corticosteroid asthma drugs act on.

With lower inflammation in the airways, your body produces mucus with fewer sticky proteins. As a result, you have lighter, easier-to-clear phlegm.

Social Confidence Returns

This is the benefit that a lot of people don't expect, but it is welcome nonetheless.

Without the disruptive mucus, people's lives are changing drastically. They never realised how much the phlegm robbed them of their personality.

Years of hiding the spitting. Years of staying silent. Years of not trying to offend anyone. They got used to it. It made them dull. It made them silent around others.

But when the mucus finally goes back to normal?

You become lively again. The dullness leaves. You're just in a better mood. You get a stronger vitality for life. Suddenly, people see you as the life of the table. You're smiling at others again. Your family notices the change.

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.

Grandparent relaxed and present with family

We've seen the feedback ourselves. Spouses that are 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.
