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.

Here's the difference doctors look for:

Healthy thin watery mucus
Healthy Mucus

Thin. Watery. Smooth.

It slides down your throat without you even noticing.

You shouldn't have to clear your throat more than 5 times a day.

Thick post-COVID mucus
Post-COVID Mucus

The inflammation keeps running. The thick mucus keeps producing.

The phlegm gets thicker. Heavier. Stickier. Harder to move.

Doctors warn this thick, stagnant phlegm is dangerous. It's unnaturally thick — and you can't clear it.

It creates warm, wet, moist conditions in the airways.

"It's the perfect breeding ground for bacteria."

Bacteria breed in the stagnant mucus. And while you lie flat at night they can seep down into the lungs.

It's a leading cause of pneumonia and other chest infections.

These are the main bacteria that thrive in 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 full devastation of this was seen in 1918. During the Spanish Flu.

Autopsy reports from the Spanish Flu show most victims died from bacterial pneumonia. Bacteria were multiplying in the thick throat phlegm after the flu had already passed.

Bacteria breeding in thick stagnant throat phlegm

Researchers say the flu itself wouldn't have had nearly as many casualties if it wasn't for the bacterial pneumonia.

1918 Spanish Flu cause-of-death chart — deaths from the virus alone versus deaths with secondary bacterial pneumonia (~50 million)

But thankfully, modern medicine means we can treat pneumonia far better than in 1918.

We aren't seeing the same number of fatalities — the technology is better.

But survivors are not leaving unharmed.

It can leave them permanently weaker — especially older adults with already-strained immune systems.

In severe cases, when the infection reaches the lungs, survivors can need oxygen support for life.

It can mean lost muscle, a higher falls risk, needing help with washing, walking, the stairs — or being moved into care.

"I was never the same after the hospital" is a common sentiment.

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. Patients were recovering, but the cough, the phlegm, the throat-clearing, all stayed.

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

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.

When doctors prescribed it:

People reported that the stubborn mucus in the airways was loosening. It could finally be brought up again.

The phlegm that was once a struggle to clear, started easily expelling out of the chest.

It calmed the constant throat clearing — no more lump in the throat feeling, no more drip.

People reported fuller, deeper breaths. It made people 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 causes your vagus nerve to become stimulated, which then signals the tiny glands in your airways to release watery fluid into your mucus.

Thick mucus breaking apart as watery fluid floods in

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.

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

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

Vagus nerve releases 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.

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.

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

What People Are Reporting

People using a proper mullein extract in 2026 report the same handful of things:

  • 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
  • Feeling at ease — knowing the mucus is finally moving

And then something unexpected starts to happen.

The fear lifts.

Because when the mucus is finally moving — thinning, clearing, coming up instead of sitting there…

When you lie flat at night and your chest feels clear, not heavy…

You stop bracing for what it could have turned into.

You're not lying awake wondering if tonight is the night it slips into your lungs.

You're not the one the family quietly worries about.

You feel like yourself again. Steady. Clear.

You get to just live again — without the thick phlegm deciding how the rest of it goes.

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 the people who try what the 1900s doctors actually prescribed report entirely different effects:

  • 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
  • Feeling confident again, leaving the house again without insecurity

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.

Introducing CleraVox Mullein Super Strength

CleraVox mullein bottle next to authentic brown extract

This is where a company called CleraVox comes in. They actually returned to a strong mullein extract.

Something the 1900s doctors would have been proud of. Brown. Concentrated.

CleraVox Mullein Super Strength bottle in motion

They saw how there were tons of fake mullein products on the market. There was very little access to real mullein. They decided to make a difference.

It's real strength. It has enough mullein compounds to break apart the thick mucus that has been building up for years.

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

It's the equivalent of 7 cups of mullein tea — in a few drops.

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

Placing CleraVox dropper under the tongue
Step 01

Place It Under Your Tongue

Squeeze 2 full droppers under your tongue. Hold for 10–30 seconds.

Alternative: Drink with water for stomach absorption.

Held under the tongue, the active compounds absorb straight into your system — the fastest, fullest way to take it.

Body producing more watery secretions in the airways
Step 02

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
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.
