Mullein for Lungs: What the Research Shows in Breathizen
Mullein is the first of the five ingredients Breathizen names, listed as Mullein Leaf Extract 10:1. It is an old cough and throat herb, but no clinical trial shows it helps the lungs, and every breathing use is rated insufficient evidence. The amount in each 4-pump dose is not published. Europe's herbal review covers the flower, not the leaf.

The plant
What is mullein, and which part does Breathizen use?
Mullein (Verbascum thapsus) is a tall roadside plant with soft, fuzzy leaves and small yellow flowers. People have brewed it for coughs and sore throats for centuries.
Breathizen's sales page lists "Mullein Leaf Extract 10:1" first among its five ingredients. The word "leaf" matters, because the best-known official review covers only the flower.
Leaf vs flower
The European Medicines Agency reviewed mullein flower, called Verbasci flos. It accepted the flower for a sore throat with a dry cough and for colds, based on long-standing traditional use alone (EMA, Mullein flower). The review is for ages 12 and up, and it says to see a doctor if symptoms last over a week.
That review does not cover leaf extract, so it cannot be borrowed as support for the leaf in Breathizen.
Label facts
Mullein in Breathizen at a glance
What the sales page says, set next to what research has used.
| Label name | Mullein Leaf Extract 10:1 |
|---|---|
| Scientific name | Verbascum thapsus |
| What it is | Leaf extract |
| Position in the list | 1 of 5 (as listed on the sales page; no amounts or weight order are published) |
| Per dose | Not published |
| Amount used in research | No established dose; classical use 3-4 g of herb a day |
| Strength of evidence | Traditional use only |
| Traditional or marketed use | Traditional herb for cough and throat comfort |
| Main caution | Too little safety data for pregnancy or breastfeeding; no human trials for breathing. |
The position in the list is not a weight order. Without a Supplement Facts panel, nobody outside the company knows whether mullein is the largest or smallest part of the spray.
Dose
How much mullein is in a daily dose of Breathizen?
Nobody outside the company knows. The sales page names the extract and its 10:1 ratio, but it prints no milligrams, and no Supplement Facts panel was published.
What "10:1" means on a label
A 10:1 ratio usually means about 10 parts of dried leaf went into 1 part of finished extract. It describes how the extract was made, not how much of it sits in your 4 pumps (0.60 mL).
| Plant part and ratio | Leaf extract, 10:1 (sales page) |
|---|---|
| Extract per 4-pump dose | Not published |
| Dried leaf it equals | Cannot be worked out without the amount |
| Older herbal texts | 3-4 g of dried herb a day (Drugs.com, Mullein) |
| Modern established dose | None (RxList, Mullein) |
What the missing number means for you
You cannot compare the spray with classical amounts of whole herb, or add up your intake if you also drink mullein tea. If that matters to you, ask the order desk at +1 (302) 200-3480 whether a full label exists, and read our Breathizen product label notes.
Research
Mullein for lungs: what does the research show?
No clinical trial shows that mullein improves lung function or breathing. Drugs.com notes a long history of use for asthma, coughs and other respiratory problems, but says clinical research is lacking (Drugs.com, Mullein).
RxList rates every respiratory use of mullein as insufficient evidence, from cough and asthma to colds and flu (RxList, Mullein).
Cough, asthma, bronchitis
Folk use only. No trial in people has tested mullein for these problems (RxList, Mullein).
Sore throat with dry cough
Accepted in Europe for the flower, on tradition rather than trials (EMA, Mullein flower).
Mullein in Breathizen
No study has tested the spray or its leaf extract at any amount.
So the badge "Natural Lung Support" rests on tradition. The sales page's stronger lines about mucus and airways go beyond these sources. For more, read our article on mullein and lung research.
Myths and forms
Does a mullein lung cleanse work?
No study shows that mullein, or any supplement, flushes out the lungs. There is no good evidence behind the "mullein lung detox" posts that circle social media.
Healthy lungs already clean themselves. A thin layer of mucus traps dust and germs, and tiny hairs called cilia sweep it up and out.
Mullein tea vs mullein spray
Mullein tea is the classic form: dried leaves or flowers steeped in hot water, then strained. Breathizen puts a leaf extract into a mix of five ingredients.
| Question | Mullein tea | Breathizen spray |
|---|---|---|
| What goes in | Dried leaf or flower only | Leaf extract plus four other ingredients |
| Do you know the amount? | Yes, you measure the herb | Not published |
| Daily effort | Brew and strain each cup | Shake, then 4 pumps once a day |
| Trials for breathing | None | None |
Safety
Mullein side effects and interactions
Mullein's main safety gap is missing data, not a long list of known reactions. RxList gives no dose range, and too few studies exist to map its drug interactions with confidence (RxList, Mullein).
In Breathizen, the bigger warnings come from the other ingredients. Bromelain and ginger can raise bleeding risk, and bromelain can trigger allergies in people who react to pineapple.
Keep every inhaler and controller medicine on the schedule your doctor set. A supplement is never a reason to cut back. Sudden or severe breathing trouble needs 911.

Order nowWho should skip it
Who should skip mullein?
Pregnant and breastfeeding women should skip it, since RxList advises against it for lack of safety data (RxList, Mullein). The sales page adds anyone under 18 or with a medical condition.
- Anyone under 18: the spray is sold for adults.
- Anyone with a cough lasting weeks, or coughing up blood: see a doctor first.
Compare
Breathizen vs taking mullein on its own
Plain mullein gives you a known amount; Breathizen gives you a one-step routine with four more ingredients. Neither has trial evidence for breathing.
Points for Breathizen
- Four pumps once a day, with no tea to brew.
- Mullein plus four other named botanicals in one bottle.
- An order desk that can see your order, and a 60-day window.
Points for mullein alone
- A single-herb product with a Supplement Facts panel shows the amount.
- Tea lets you measure the herb yourself.
- Fewer ingredients means fewer allergy and bleeding cautions.
Bottom line
Should mullein sway your choice?
Mullein has a long folk record and a European nod for its flower, but no lung trials. Breathizen uses the leaf at an unpublished amount. Treat it as a traditional herb, not as proof the spray works.
The other four
What else is in Breathizen besides mullein?
Mullein is listed first, followed by ginger, bromelain, lemon and Cordyceps militaris. Compare them all on the Breathizen ingredients page.
FAQ
Mullein for lungs: common questions
Is mullein good for lungs?
It has not been shown to be. Mullein has a long folk history for coughs, but clinical research is lacking, and RxList rates all its breathing uses as insufficient evidence. No trial has tested the leaf extract in Breathizen. Treat any lung benefit as unproven, and keep your prescribed care.
Does mullein help with mucus?
No study in people shows that it does. Mullein is a traditional remedy for coughs with phlegm, and the Breathizen sales page talks about loosening mucus, but the monographs we use find no clinical support. Thick mucus that lasts a month or more is worth a doctor visit.
Does mullein help with allergies?
There is no good evidence that mullein eases hay fever or other allergies. It is not rated for allergy use in the sources we checked. Saline rinses, allergy medicines and nasal sprays have stronger support, and an allergist can test what you react to.
Does mullein work?
For breathing, nobody knows yet, because the trials have not been done. The best support is the European traditional-use review of mullein flower for a sore throat with a dry cough. Breathizen uses the leaf, at an amount it does not publish, so that review does not transfer.
What is the mullein for lungs dosage?
There is no established dose. Older herbal texts describe 3-4 g of dried herb a day, but modern research has not confirmed any amount. Breathizen does not publish how much mullein leaf extract is in its 4-pump daily dose, so the spray cannot be compared with those figures.
How do you take mullein leaf extract in Breathizen?
The sales page says to shake the bottle and spray 4 pumps (0.60 mL) into the mouth or onto the tongue once a day, ideally in the morning before the first meal. The mullein comes mixed with the other four ingredients; it is not sold or dosed on its own.
Is mullein spray for lungs better than mullein tea?
No research compares them, so neither form can claim to be better. Tea lets you measure the herb yourself. A spray is quicker, but in Breathizen the amount is not published. Neither has been tested in a trial for breathing.
