If you’ve ever bought a lung supplement only to feel... nothing, you’re not alone.
Many over-the-counter respiratory products are just repackaged herbal teas or outdated formulas. They rely on a single ingredient with limited research or use small doses that aren’t enough to move the needle.
But here’s the truth:
If your lungs are clogged with mucus, inflamed, or tight, you need targeted, multi-layered support. That means ingredients that clear airways, reduce inflammation, break down thick mucus, and help your lungs relax enough to expand properly.
That’s where the right natural compounds shine.
Some herbs have been used for centuries to treat chronic coughs, wheezing, and breathlessness. Now, modern science is catching up—validating these natural remedies with real data, and revealing how they support lung function at a cellular level.
In this blog, we’ll break down the top research-backed ingredients that:
✅ Help you breathe deeper
✅ Clear stubborn mucus
✅ Ease tightness in the chest
✅ Support energy and oxygen flow
And if you’re looking for a shortcut that includes all of these in one daily capsule?
Let’s start by looking at how these natural ingredients actually work inside your lungs.
How Lung-Supporting Ingredients Actually Work
Your lungs are one of the most oxygen-hungry organs in your body—and also one of the most exposed. Every breath pulls in not just air, but also dust, allergens, pollutants, and microbes. That’s why your lungs rely on multiple defense systems: mucus to trap intruders, cilia to sweep them out, and inflammation to fight off threats.
The problem? When these systems are out of balance, you end up with too much mucus, too much inflammation, and not enough clear airflow.
That’s where the right natural ingredients can make a difference.
🌬️ The 3 Key Lung Support Functions
Mucolytics – Compounds like serratiopeptidase and mullein help break down thick, sticky mucus that blocks your airways.
Anti-inflammatories – Ingredients such as vitamin D3 and ivy leaf help calm inflamed tissue so your lungs can expand fully.
Bronchodilators – Peppermint oil and coltsfoot help relax the smooth muscles in your airways, making it easier to inhale deeply and cough productively.
These mechanisms aren’t magic—they’re rooted in how your lungs are designed to function. The right support simply helps your body return to balance.
According to Flavour and Fragrance Journal, many essential oils and herbal compounds show measurable anti-inflammatory and antimicrobial effects when applied to respiratory conditions (source).
Now let’s break down the most powerful ingredients for lung support—starting with one that’s been used for centuries: mullein.
Mullein — The Soothing Mucus-Breaker
If you’ve ever struggled with stubborn mucus, deep coughing fits, or that “stuck” feeling in your chest, mullein is one of the most effective natural remedies you can try.
Mullein (Verbascum thapsus) has been used for centuries to treat respiratory complaints. It’s known for its ability to:
Soothe irritated airways
Loosen and thin mucus
Reduce inflammation in the lungs
But this isn’t just folk medicine. A study published in Biology confirmed that mullein contains multiple active compounds that show both anti-inflammatory and mucolytic activity. It supports healthy lung secretions and helps calm excessive coughing—especially in cases of chronic bronchitis (source).
How It Works
Mullein coats inflamed mucous membranes, easing irritation and helping your body expel mucus more easily. It also supports cilia function—the little hair-like structures in your airways that sweep out unwanted particles.
If you’re constantly clearing your throat, waking up congested, or feeling like something is stuck in your chest, this plant could be your best friend.
That’s why mullein is a core ingredient in LungExpand Pro. We also covered mullein in depth in our Ultimate Guide to Clearing Your Lungs Naturally if you’d like a broader look at how it fits into the full recovery process. It works synergistically with other herbs like ivy and enzymes like serratiopeptidase to help clear your lungs from the inside out.
Next, let’s explore another powerful plant that works differently—but just as effectively: ivy leaf.
Ivy Leaf — Nature’s Lung Expander
While mullein works to soothe and loosen mucus, ivy leaf extract helps you cough that mucus up and get it out.
This climbing plant may look decorative in your backyard, but it’s actually one of the most clinically validated herbs for respiratory health. In Europe, ivy leaf extract is commonly used as a natural treatment for chronic bronchitis, and it’s approved in Germany as an over-the-counter remedy for productive coughs.
📈 Backed by Clinical Data
A review published in Natural Products and Human Diseases found that ivy (Hedera helix) extract improves breathing, reduces bronchial constriction, and enhances mucus clearance in the lungs. The saponins in ivy help increase surfactant production, making it easier for your airways to stay open during exhalation (source).
Ivy also acts as a bronchodilator, meaning it helps relax and widen the bronchial passages. This is crucial for people who experience tightness in the chest or feel like they can’t quite “get the air all the way in.”
Why It Matters
When you’re congested or inflamed, mucus tends to settle in the lower lungs and becomes harder to expel. Ivy leaf extract makes your coughs more effective by thinning that mucus and opening the bronchial tubes so your lungs can push it out.
That’s why it’s not only useful during colds—but also as part of your daily lung maintenance routine.
We explore how ivy pairs with other ingredients like serratiopeptidase and vitamin D3 in our Ultimate Guide to Clearing Your Lungs Naturally.
Serratiopeptidase — The Enzyme That Melts Mucus
Unlike herbs, serratiopeptidase is a proteolytic enzyme. It doesn’t grow in nature like mullein or ivy—it’s produced through fermentation by a species of friendly bacteria. But its impact on your lungs can be dramatic.
Originally studied for reducing post-surgical swelling and inflammation, serratiopeptidase has more recently gained attention for its ability to break down mucus, biofilms, and dead tissue in the body—especially in the lungs.
🧪 How It Works
When mucus becomes thick and sticky, it clogs your airways and traps bacteria. Serratiopeptidase works like a microscopic cleanup crew—breaking down excess proteins in mucus so it becomes thinner and easier to expel.
This not only clears your lungs faster, it also helps you avoid recurring infections that thrive in stagnant mucus environments.
🩺 Backed by Research
A study in Frontiers in Pharmacology highlighted serratiopeptidase as a promising adjuvant for respiratory issues, noting its anti-inflammatory, fibrinolytic, and mucolytic properties. Researchers also explored its potential in cases of COVID-19 lung inflammation, showing measurable improvements in breathing and oxygenation (source).
It’s especially helpful for people with:
Persistent post-infection congestion
Mucus buildup from allergies or chronic irritation
A history of frequent respiratory infections

Peppermint Oil + Coltsfoot — Fast-Acting Airway Support
While herbs like mullein and ivy work gradually to rebuild respiratory health, some ingredients offer faster, more immediate relief—especially for tension, tightness, or spasms in the airways.
That’s where peppermint oil and coltsfoot come in. These two natural ingredients deliver quick results by relaxing smooth muscles, calming inflamed tissue, and promoting clearer breathing on demand.
🌿 Peppermint Oil: Cooling and Opening the Airways
Peppermint contains menthol, which interacts with cold-sensitive receptors in your throat and chest. This produces a soothing, cooling effect that reduces the urge to cough and helps open the airways.
Acts as a mild bronchodilator, helping widen the bronchial tubes
Has antimicrobial and anti-inflammatory properties
Can improve nasal airflow and reduce chest tightness
A study in the Avicenna Journal of Phytomedicine found that peppermint oil improved exercise performance and respiratory efficiency by helping relax bronchial smooth muscle and enhance oxygen uptake (source).
🌼 Coltsfoot: The Wet Cough Soother
Coltsfoot (Tussilago farfara) is less well-known, but has a long tradition of use in European herbal medicine for treating wet coughs and mucus-heavy lungs.
It’s an expectorant and demulcent—meaning it helps both loosen mucus and soothe irritated tissue at the same time. It’s especially helpful when your cough is productive but painful or spasmodic.
Better Together
Peppermint offers immediate relief and airflow support, while coltsfoot calms irritation and helps you clear out stuck mucus.

Vitamin D3 — The Underrated Lung Protector
When most people think of vitamin D, they think of bone health or immune support. But few realize how essential vitamin D3 is for your lungs.
Research shows that vitamin D plays a critical role in regulating inflammation, maintaining lung tissue integrity, and reducing susceptibility to respiratory infections. In fact, people with chronic lung conditions often have low vitamin D levels—especially during colder months when sun exposure drops.
🛡️ Why Vitamin D3 Matters for Breathing
Reduces airway inflammation that contributes to tightness and reduced airflow
Supports immune defense in the respiratory tract to reduce infections
Helps modulate cytokines, which are signaling molecules involved in chronic inflammation
A clinical study published in Clinical and Experimental Immunology found that vitamin D supplementation led to fewer respiratory infections and improved lung immunity in people with chronic respiratory issues (source).
Why Most People Don’t Get Enough
Your body makes vitamin D when your skin is exposed to sunlight. But with age, darker skin tones, indoor lifestyles, and sunscreen use, deficiency is extremely common. And typical multivitamins often don’t contain enough D3 to support lung health at a therapeutic level.
That’s why LungExpand Pro includes a meaningful dose of vitamin D3, along with mucolytic and anti-inflammatory compounds, for a well-rounded daily approach.
