My husband smoked for 40 years. I bought this because I was tired of lying awake listening to him cough. He didn’t say much about it, but he’s slept through two nights in a row now, and so have I.
90-Day Money Back Guarantee
Give it 90 days. If the mornings aren’t quieter and the nights aren’t easier, send it back for a full refund. The only thing you have to lose is the cough.
How It Works
+
Most remedies fail for the same reason: they don’t stay where the trouble starts.
Syrups and teas wash past your throat in seconds. Pills dissolve in your stomach. By the time anything reaches the irritated tissue setting off your cough, it’s already gone — which is why relief lasts minutes, not hours.
TrueFlow is different because of where it goes. Two sprays into the back of your mouth, twice a day, coat the throat directly with four plant actives chosen for one job: to calm the irritation that triggers the fits and leave your breath feeling cooler and more open.
Most people feel the difference within the first few sprays. The mornings get quieter from there.
Ingredients
+
Four plants. Nothing else. No pills, no synthetics, no harsh chemicals.
Peppermint. Natural menthol creates a cooling sensation that makes every breath feel clearer the moment it lands.
Eucalyptus. Long used to open up a tight, heavy chest and make breathing feel easier.
Licorice Root. A traditional remedy for a raw, irritated throat — the kind that sets off coughing fits.
Calendula. Soothes sensitive tissue and supports the throat through years of wear.
Vegan. Non-GMO. Made in a GMP-certified facility in the USA.
If you take medication for blood pressure or heart conditions, check with your doctor before use.
Shipping & Delivery
+
Free shipping across the USA on every order. Most orders ship within 24 hours and arrive in 8-10 business days. International delivery to 20+ countries takes 7–14 days, fully tracked and insured.
Covered by our 90-day money-back guarantee. If TrueFlow isn’t working for you, send back what’s left for a full refund — even an empty bottle.

TrueFlow™ Breathing Guide (e-book)
Why Most Lung Cleaners Fail (And Why TrueFlow™ Doesn't)
Most lung products fail for the same reason, and it has nothing to do with the ingredients.
Cough syrups wash past your throat in seconds. Lozenges only coat the front of your mouth. Pills dissolve in your stomach. Teas and honey are gone in a minute.
None of them stay where the trouble actually is: the raw, irritated tissue at the back of your throat that fires off every coughing fit. That’s why relief lasts minutes, and why 40 years of trying everything hasn’t fixed it.
TrueFlow was built around that one failure. Two sprays go directly into the back of your mouth and coat that irritated tissue on contact — then stay there, instead of being swallowed or diluted.
Peppermint cools it the moment it lands, eucalyptus eases the tight, heavy feeling, and licorice and calendula soothe the rawness that keeps the cough reflex on a hair trigger.
Same kind of plants other brands put in pills and teas. Delivered to the one place pills and teas can’t reach.

The #1 lung cleanser spray that actually works

Smoked 42 years, quit three years ago, and the morning cough never went away. Honest to god I thought I was stuck with it. Three weeks on TrueFlow and the hour I used to spend at the bathroom sink is down to maybe five minutes. My throat doesn’t feel raw by lunchtime anymore. For $27 I’d call that a bargain.

After decades of smoking I’ve tried every syrup, lozenge and tea on the shelf. Didn’t expect much from a spray either. What I can tell you is my throat feels less raw and I’m not stopping halfway up the stairs the way I was. Not a miracle, but the first thing in years that actually did something I can feel. Four stars because I wish the bottle lasted longer.

Soothe Your Throat. Breathe Easier.
Each plant was chosen for one job: calm the raw, irritated throat tissue that keeps your cough on a hair trigger — the one place other remedies never stay long enough to help.
Eucalyptus: Opens up that tight, heavy feeling at the back of your throat so every breath feels a little clearer.
Peppermint: Natural menthol cools the irritated tissue on contact — the sensation most people notice from the very first spray.
Licorice Root: A traditional remedy for a raw, inflamed throat — the kind that sets off coughing fits before you’ve even finished a sentence.
Calendula: Soothes tissue worn down by years of coughing, smoke and dryness, and supports it as it recovers.
Four plants, working on the exact spot where the trouble starts. No pills to swallow. No syrups to wash past. No harsh chemicals or synthetic ingredients.
Most people feel the cool, calming effect within the first few sprays. The mornings get quieter from there.
Your Journey Ahead
Follow your progress and see what's ahead on your path to success
Week 1-2
The First Change You’ll Feel
The cool, calming sensation hits on your very first spray. By the end of week one, the hour at the sink becomes a little shorter, your throat feels less raw by lunchtime, and that constant tickle that triggers coughing fits begins to quiet down.
Week 3-4
Quieter Mornings, Easier Nights
The morning ritual gets noticeably shorter. Lying down at night stops triggering a fit the moment your head hits the pillow. Your partner may notice before you do. Breathing feels lighter, especially first thing after waking, and the stairs start to feel a little less steep.
Week 5-6
Settling In
Daily coughing fits are no longer the backbone of your morning. Breathing feels more comfortable throughout the day: on the phone, in conversation, climbing stairs, walking the dog. The things that used to set you off (cold air, laughing, lying flat) don’t hit the way they used to.
Week 7-8+
The New Normal
The easier breathing isn’t a change anymore. It’s just how your mornings and nights feel. Most long-term users keep TrueFlow in their daily routine the way they’d keep a toothbrush. If you’ve quit smoking in the past, this is often where you finally feel like you got the payoff you’d been waiting years for.
Frequently Asked Questions
How do I use it?
+
Two sprays into the back of your mouth, twice a day. That’s it. No pills, no routine, no equipment.
When will I feel the difference?
+
Most people feel a cool, calming sensation on the very first spray. The quieter mornings tend to show up within the first two weeks.
Can I use it if I still smoke?
+
Yes. TrueFlow helps calm the raw, irritated throat tissue whether you’re still smoking, trying to quit, or quit years ago.
How is TrueFlow™ different from other lung cleansers?
+
Most lung products come as pills, syrups or teas, which means they wash past your throat in seconds on the way to your stomach. TrueFlow is a direct spray, so the ingredients stay on the raw, irritated tissue at the back of your throat where coughing fits actually start. That’s why most people feel it working right away.
I’ve tried everything. Why would this be any different?
+
Because it isn’t trying to do what everything else did. Cough syrups, lozenges, teas and honey all work on the front of the mouth or the stomach. TrueFlow works on the one spot none of them stay long enough to help: the back of the throat.
Is it safe?
+
It’s made from four plant ingredients with no synthetics or harsh chemicals. If you take medication for blood pressure or heart conditions, check with your doctor first (licorice root can interact with some prescriptions).
Will it interfere with my inhaler or other medications?
+
Use TrueFlow separately from your inhaler, with a few minutes between. If you’re on daily prescriptions, especially for blood pressure or heart, run it past your doctor first.
How long does one bottle last?
+
Thirty days at the recommended two sprays, twice a day.
