They're saying the symptoms never left after COVID. They've never fully recovered since.

Why Phlegm Becomes Thick After COVID

When a virus clears, the inflammation is supposed to leave with it. But in 2021, a team of French researchers noticed something strange in regards to COVID.

The virus clears. But the inflammation stays.

Study showing inflammation persists 5 months after mild COVID

COVID inflammation can linger for years after the virus is gone.

Here's why that's a problem:

Your body still thinks it's under attack. Inflamed airways cause your body to produce thicker, heavier mucus to trap and catch viruses.

Your body doesn't get the memo. It keeps producing heavier thick phlegm in the throat and chest.

The phlegm builds up and hardens. It clings to the walls of your airways. You can't cough it up normally anymore.

Some people can feel it when they lie down flat. A drowning sensation in the chest.

The Usual Fixes From Doctors

If you've dealt with this for long enough, you start to try different medications.

But here's why they've fallen short:

Hand holding a box of Mucinex
Fix #1

Mucinex (guaifenesin)

Guaifenesin was approved in 1952 — for chest colds that clear in a week.

It was never built for inflammation that won't switch off.

It assumes the cause goes away on its own. Post-viral inflammation doesn't. So the mucus always comes back.

Hand holding antihistamine allergy tablets
Fix #2

Antihistamines (Piriton, Zyrtec, Claritin)

These are allergy pills. They block histamine — your body's allergy alarm.

But this isn't an allergy.

So they're aimed at the wrong target — they do nothing for post-viral inflammation.

Hand holding steroid tablets
Fix #3

Steroids (corticosteroids)

If your doctor diagnosed you correctly, this is what you would likely be prescribed.

Steroids work — they force the inflammation down fast.

But you can't stay on them. Stop, and it can come roaring back — worse than before.

So your body just ends up relying on a drug — that's not a fix.

People are reporting years of failed medications. They tried anything and everything, PPIs, steam inhalers, even dehumidifiers.

We are not exaggerating. Years. People have been going through this. They get COVID in 2021 and are still frantically searching for any relief to this day.

And only one plant is showing up with any sort of positive reception.

We looked into it for you. To see if this is genuinely real or another internet hoax.

The Forgotten Mullein Remedy From The 1900s

Mullein plant with yellow flowers

During the 1918 Spanish Flu, we saw the exact same thing happening. We now know they were going through post-viral inflammation.

Patients were recovering from the flu. But the cough stayed. The phlegm stayed. The throat-clearing stayed.

Back then, medicine looked nothing like it does today.

Doctors always tried to tie a condition back to its root cause. They were paid very little, and often tried to genuinely heal patients for good.

There was no patent drugs. No big pharma. They relied on plant remedies. They believed through herbs any ailment, any disease could be treated.

At the time they relied on a powerful mullein remedy to clear out stuck, stubborn mucus in the throat and lungs.

1900s-style illustration of the mullein remedy

It was a specific type of mullein extract.

It took days to make.

They ground down dried mullein leaf and submerged it in strong alcohol. They would then let the solution sit. Day after day, the alcohol worked deeper into the leaf — drawing the compounds out of the plant tissue, layer by layer.

Dried mullein leaves steeping in alcohol, amber-brown colour leaching from the leaves into the liquid

You could see the extract get stronger and more concentrated with your own eyes. Each day it would become a deeper and deeper amber color.

By the end of it they had a powerful tincture that was deep brown. Filled with mullein compounds.

The results were undeniable.

People reported the mucus in the airways loosened.

The phlegm that was once a battle to clear every morning, started to easily expel out of the chest.

It calmed the need to constantly clear their throat.

They reported deeper, fuller breaths. It made them feel normal again.

The Research Behind Mullein — What Does The Science Actually Say

The science behind how mullein clears mucus

During the research, we noticed something strange.

Mullein in the 1900s had a very positive reception. A famous, widely known remedy.

But in 2026, the reception is a lot more mixed. Some people swear by mullein for all phlegm issues. But some people report no changes at all.

We decided to look for the truth. The genuine research on mullein.

Looking deep into the compounds of the plant. Dissecting the mechanisms behind it all. Reading what doctors are saying. Analysing .

What we found was shocking.

The 10 studies we reviewed
Study 01 · 2021 Anti-Inflammatory Activity of Mullein Leaf Extract Phytochemical Analysis and Anti-Inflammatory and Anti-Osteoarthritic Bioactive Potential of Verbascum thapsus L. Leaf Extract. PMC8434610. 2021. Finding: Mullein leaf extract significantly decreased multiple inflammation markers (IL-6, COX-2, iNOS, MMPs) in laboratory cell models — the same inflammation pathways involved in irritated, overworked mucous membranes that drive chronic throat clearing.
Study 02 · 2024 Multifaceted Biological Properties of Verbascoside MDPI Antibiotics, PMC12291726. 2024. Finding: Mullein's signature compound verbascoside has documented anti-inflammatory, antioxidant, and immunomodulatory effects confirmed across multiple in vitro and in vivo studies.
Study 03 · 2024 Antiviral Activity Against Respiratory Pathogens Referenced in PMC12291726 (2024 verbascoside review). Finding: Mullein leaf and flower extracts showed antiviral activity against several pathogens — including a common human coronavirus, Hepatitis B virus, and Herpes Simplex 2 — in laboratory studies. Supports mullein's traditional use for respiratory complaints.
Study 04 · 2005 Expectorant + Bronchodilatory Effects Phytotherapy Research, 2005. Finding: Mullein extract demonstrated expectorant (mucus-clearing) and bronchodilatory (airway-opening) effects in animal models — direct mechanistic support for thinning and clearing thick mucus.
Study 05 · 2002 Biological Activity of Common Mullein Turker & Camper. Journal of Ethnopharmacology, 2002. PubMed PMID 12241986. Finding: Identified mucilage (3%) as responsible for soothing mucous membranes, and saponins as responsible for expectorant action. Also confirmed antibacterial activity against Klebsiella pneumoniae, Staph aureus, and E. coli.
Study 06 · 2014 Saponin Mechanism in Expectorant Therapy Clinical Application of Expectorant Therapy in Chronic Inflammatory Airway Diseases. International Journal of Molecular Medicine, PMC3961124. 2014. Finding: Triterpenoid saponins — the class mullein contains — are the major effective ingredient in herbal expectorant therapy. They reduce sputum stickiness by acting as natural surfactants, and stimulate the gastro-pulmonary vagal reflex that increases watery airway secretion.
Study 07 · 2003 Antibacterial Activity Against Respiratory Pathogens Sampson & Kaur. Journal of Ethnopharmacology, 2003, 88(1), 67–71. Finding: Mullein leaf extract has antibacterial activity against several pathogens including respiratory ones.
Study 08 · 2012 Antispasmodic + Airway-Relaxing Activity Ali et al. BMC Complementary and Alternative Medicine, 2012. PMC3350428. Finding: Mullein extract showed antispasmodic activity, including airway-relaxing effects mediated through calcium channel modulation — meaning it helps calm the involuntary throat-clearing reflex.
Study 09 · 2019 Antioxidant + Antimicrobial Properties The Antioxidant, Anticarcinogenic and Antimicrobial Properties of Verbascum thapsus L. PubMed PMID 31456524. 2019. Finding: Confirmed multiple bioactive compounds in mullein (sesquiterpenes, flavonoids, saponins, lignins) with antioxidant and antimicrobial activity.
Study 10 · 2022 Comprehensive Review of Mullein's Therapeutic Potential Jan et al. Health-promoting and disease-mitigating potential of Verbascum thapsus L. (common mullein): A review. PubMed PMID 35088467. 2022. Finding: Reviewed the full literature and confirmed mullein's documented antiviral, antioxidant, analgesic, sedative, anti-inflammatory, antibacterial, and antifungal pharmacological properties.

Mullein contains specific compounds called saponins. The plant is rich in it.

And how saponins work are remarkable.

Magnified active compounds of mullein — saponins, verbascoside, mucilage and flavonoids

When saponins are digested in the stomach, they react with the gut-lining in a peculiar way.

The reaction stimulates your vagus nerve. Which then wakes up tiny airway glands called submucosal glands.

Here's why that's important:

When activated, the submucosal glands release a watery fluid inside of your airways.

So the thick phlegm that's clinging to the walls of your airways? It softens. Breaks apart. Becomes easy to expel.

Thick mucus breaking apart as watery fluid floods in

The extra fluid breaks apart the thick, stuck mucus — until it can finally move and clear.

This is how mullein has worked all of these years. It's only due to modern science that we now know how it works.

Doctors call it the gastro-pulmonary reflex.

To break it down simply:

1
Saponins entering the stomach

Saponins enter stomach

2
Saponins reacting with the stomach lining

React with gut-lining

The saponins react with the stomach which stimulates the vagus nerve.

3
The signal travelling up the vagus nerve to the airways

Vagus-nerve becomes stimulated

The vagus-nerve signals the tiny glands lining your airways to release thin, watery fluid.

4
Watery fluid thinning the thick mucus in the airway

Submucosal glands release fluid inside of the thick mucus

That fluid soaks into the thick phlegm. It breaks it apart. So your body can finally move it up and out.

You can feel it happening.

You wake up. And your mucus suddenly feels looser and easier to cough up.

You can finally flush out the old, stuck phlegm you couldn't shift before. It becomes effortless.

Your throat feels un-clogged. Your lungs feel like there's a weight removed from them.

It's because all the phlegm that was stuck finally gets to clear out and exit.

Doctors are actually starting to recommend it today. It's amazingly gentle at clearing out the mucus. It doesn't leave harmful side effects. No harsh drugs are needed.

One lung clogged with mucus, the other clear, above a Cleveland Clinic quote describing mullein as an expectorant that thins mucus

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

But all of this still doesn't answer our question.

Why is the perception about mullein mixed today?

Why do some people say that it works for them and others say it doesn't?

The Overlooked Problem With Mullein

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

We found the answer quickly. And we didn't have to look long.

Over the internet and Amazon, mullein is flooded with cheap supplements that likely contain very little mullein.

  • Weak mullein herbal tea mixes
  • Mullein capsules
  • Pineapple-flavoured mullein gummies
  • Watered-down extracts

Many people end up trying these. Feel no effects. And rule out mullein for good.

But people who try the kind of mullein doctors used in the 1900s? Report very different results:

  • Waking up and being able to breathe clearly
  • Sleeping through the night without choking on mucus
  • Speaking clearly without stopping mid-sentence to clear their throat
  • Breathlessness slowly leaving. More energy for daily tasks.

It's because the doctors of the 1900s prescribed concentrated mullein extracts.

NOT the watered-down extracts you see today.

Green-coloured mullein extracts sold online

What is on the market today is mainly an artificial dark green liquid.

Here's the problem with that:

When you extract a mullein leaf properly, the liquid is light brown at first.

Then, as it concentrates, it darkens into a deep amber.

Authentic concentrated brown mullein extract

That's what a real, concentrated mullein extract looks like.

Brown. Not dark green.

If it's green, it likely contains either very little mullein or artificial dyes and colouring.

Making a weak, watered-down mullein extract destroys the whole purpose.

It misses the entire point of why the doctors used tinctures in the first place.

It was meant to be a reliable, powerful way to utilise the plant's full mucus-clearing potential.

So where do you find a mullein remedy that's genuinely concentrated?

Something the 1900s doctors would have actually been proud of? Something they would give to their own patients.

CleraVox Mullein Super Strength concentrated brown extract

That's where CleraVox comes in.

A mullein extract based on the 1900s mullein remedy — made better.

Specifically designed to clear out and drain the thick phlegm in the throat and lungs.

It's brown. Concentrated.

Something the doctors of the 1900s would have been proud of. Something they would have given to their patients.

CleraVox Mullein Super Strength bottle in motion

CleraVox saw all the fake mullein products. How they're making weak extracts. Candied gummies. They decided to actually make a difference.

A mullein extract that is truly concentrated. Filled with active compounds to break apart the thick mucus building for years.

One serving gives you 3,500mg of extract. That is strong. Nothing like a watered-down extract.

It's the equivalent of 7 cups of mullein tea — in a few drops. Exactly how the traditional doctors would have done it.

One CleraVox dropper equals several cups of mullein tea

No alcohol. This was the one thing that the 1900s doctors couldn't do. They needed strong alcohol to make their extracts.

CleraVox uses a modern extraction method. It pulls out the same concentrated mullein compounds. The same deep, brown strength.

Only this time, without the alcohol. So it's gentle enough to take everyday.

How To Take CleraVox

Taking CleraVox mullein drops
Step 01

Take Your Drops

Squeeze 2 full droppers into a glass of water — or straight into your mouth — and swallow.

Take it with or without food, once in the morning and once at night.

The saponins travel down to your stomach, where they react with the gut-lining — and that's what starts the whole process.

Step 02

Your Body Makes More Watery Secretions

In your stomach, the saponins react with the gut-lining and stimulate your vagus nerve.

It activates submucosal glands in your airways — releasing watery fluid that thins out the mucus, so it can finally clear.

The mucus clears and the throat calms
Step 03

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.

Here's What People With Post-COVID Mucus Are Saying About It

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.
