Breathizen's brand publishes five botanicals and, unusually, publishes the limits of the research behind each one. This page takes them in turn — and then covers the two extra ingredients that appear only on the page selling the product.
The direct answer
Five botanicals: mullein leaf extract 10:1, ginger root extract, bromelain powder, organic lemon extract and organic Cordyceps militaris. All sit inside a single 154 mg blend with no individual amounts, far below every studied dose. The seller's page adds two more the brand never lists.
Breathizen is swallowed, not inhaled. It cannot open an airway and must never replace a rescue inhaler, prescribed asthma or COPD medication, or oxygen therapy — the brand's own published material says the same. If you have shortness of breath, a persistent cough, wheezing or chest pain, see a doctor: those symptoms have many causes and several are serious.
The five the brand publishes
| Ingredient | Amount on label | Research context |
|---|---|---|
| Mullein Leaf Extract 10:1 (Verbascum thapsus) | undisclosed | Traditional use; human clinical evidence lacking |
| Ginger Root Extract (Zingiber officinale) | undisclosed | 109 RCTs; strongest for nausea, not respiratory endpoints |
| Bromelain Powder (from Ananas comosus) | undisclosed | Studied at 500–1,000 mg daily; preparation-specific |
| Organic Lemon Extract (Citrus limon) | undisclosed | Not standardised; no quantified vitamin C on the label |
| Organic Cordyceps militaris Fruit Extract (Cordyceps militaris) | undisclosed | 5 human studies, 321 participants; limited and inconsistent |
One number for all of them
The label declares a 154 mg proprietary blend and nothing else. Not one of the five has a published amount. For ingredients studied at hundreds or thousands of milligrams, that single figure is the whole story: bromelain's research range alone (500–1,000 mg) is several times the entire blend, and the blend still has to cover four other ingredients. Whatever the split, every ingredient here is far below its studied dose.

Every ingredient, examined
1. Mullein Leaf Extract 10:1 (Verbascum thapsus) Partly
What is mullein, and does it help breathing?
A traditional herb long associated with the throat and chest. Its history is genuine and old — but history is not clinical proof.
Reviews indexed by the US National Library of Medicine document mullein's long traditional use for respiratory complaints and identify saponins and flavonoids in Verbascum species. The same reviews state plainly that clinical trials supporting most of those traditional uses are lacking. Breathizen's own press release makes exactly this point and declines to claim the product treats bronchitis, asthma, cough or congestion.
Worth knowing: Generally well tolerated; the 10:1 notation describes concentration, not an amount you can check. · NCCIH — herbs at a glance
2. Ginger Root Extract (Zingiber officinale) Partly
Is the ginger here doing anything for your lungs?
Ginger has the strongest research record in this formula — but almost none of it is about lungs, and the trials used gram-level doses.
A systematic review covering 109 randomised controlled trials found the most consistent results for certain kinds of nausea, with inflammatory and metabolic endpoints ranging from very low to moderate certainty. Breathizen's own press release states this research does not establish that its ginger improves lung capacity, raises oxygen levels, removes toxins from the lungs or treats respiratory inflammation.
Worth knowing: Can affect bleeding and may interact with anticoagulants such as warfarin; discuss before surgery. · NCCIH — ginger
3. Bromelain Powder (from Ananas comosus) Not supported
Does bromelain dissolve mucus in your lungs?
No — and Breathizen's own press release specifically declines to make that claim, even though the page selling it leads with mucus relief.
Bromelain is a group of protein-digesting enzymes from pineapple with a real biochemical literature. Studies use different preparations, concentrations and delivery routes, typically at 500–1,000 mg daily, so findings do not transfer between products. The brand says it does not characterise bromelain as clinically established to dissolve mucus, clear chest congestion or repair respiratory tissue in this formula.
Worth knowing: May affect bleeding, can interact with anticoagulants and some antibiotics; avoid with pineapple allergy. · NCCIH — herbs at a glance
4. Organic Lemon Extract (Citrus limon) Not supported
Is this a meaningful source of vitamin C?
There is no way to tell, because no amount of vitamin C is declared — and the brand itself warns against assuming one.
Lemon-derived material contains phenolic compounds, flavonoids and, in the oil, monoterpenoids. But 'lemon extract' is not a standardised composition: what is present depends on plant part, extraction method and processing. Breathizen's press release states that its lemon extract should not be read as a specified vitamin C dose unless a quantified amount appears on the Supplement Facts panel. None does.
Worth knowing: Citrus is generally well tolerated; the immune claims attached to it here are not supported by a declared amount. · NIH ODS — vitamin C
5. Organic Cordyceps militaris Fruit Extract (Cordyceps militaris) Not supported
Does cordyceps increase your lung capacity or oxygen?
The human evidence is small and inconsistent, and the brand explicitly says it must not be converted into a lung-capacity or oxygenation claim.
A 2026 narrative review of Cordyceps militaris supplementation in healthy people found five eligible intervention studies published between 2017 and 2024, covering 321 participants in total, with substantial variation in duration and dose and limited, inconsistent results for exercise performance and recovery. Note also the species: the page selling Breathizen lists Cordyceps sinensis, a different organism from the militaris the brand names.
Worth knowing: Little safety data at high intake; caution with immune-modulating medication and in autoimmune conditions. · NCCIH — herbs at a glance
The two that appear only on the seller's page
For completeness, because they are advertised as part of Breathizen:
- Bacopa monnieri. A herb studied mainly for memory and cognition — the selling page says so itself, calling it cognitive-enhancing — with no established respiratory role. It is not on the brand's list.
- Green tea extract. A genuine antioxidant source that also contains caffeine. It appears on a page that separately promises “No Stimulants”, and it is not on the brand's list either.
The seller also names Cordyceps sinensis where the brand names Cordyceps militaris. These are different organisms with different research literatures, and the distinction is not cosmetic.
Reading the formula as a whole
The five botanicals are a defensible, food-adjacent selection, and the brand's candour about their evidence is better than most of this category manages. What undoes it is arithmetic and route: 154 mg split five ways, swallowed rather than inhaled. The ingredients are real; the doses are not at research level, and the delivery does not reach the organ being marketed.
Cautions and interactions
- Ginger and bromelain: both can affect bleeding and may interact with anticoagulants such as warfarin; bromelain may also interact with some antibiotics. Stop before surgery.
- Pineapple allergy: bromelain is pineapple-derived.
- Cordyceps: limited safety data at higher intakes; caution with immune-modulating medication and autoimmune conditions.
- Green tea extract (seller's list only): contains caffeine, which matters for sleep and blood pressure.

Questions people ask about this
What are the ingredients in Breathizen?
The brand publishes five: mullein leaf extract 10:1, ginger root extract, bromelain powder, organic lemon extract and organic Cordyceps militaris fruit extract, together in a 154 mg blend. The page selling it lists seven, adding bacopa monnieri and green tea extract.
Does Breathizen have a Supplement Facts panel?
The label declares a 154 mg proprietary blend total, with no amount for any individual ingredient, so nothing can be checked against its research.
Does bromelain clear mucus from the lungs?
Not as sold here. The brand specifically declines to say its bromelain is clinically established to dissolve mucus, clear chest congestion or repair respiratory tissue — and the spray is swallowed, so it never reaches the lungs.
Is there caffeine in Breathizen?
Not on the brand's five-ingredient list. The seller's seven-item list includes green tea extract, which does contain caffeine, beside its own “No Stimulants” claim.
