Breathizen's label lists a 154 mg proprietary blend of three botanical extracts plus six inactive ingredients — and nothing else. This page walks through all of them, including the honest limits of what a “proprietary blend” label tells you.
The Active Blend — 154 mg Per Serving
Mullein Leaf Extract 10:1 (Verbascum thapsus)
The formula's centerpiece. Mullein has been used for respiratory comfort in European folk medicine for centuries — the tall “torch plant” found along roadsides across three continents. The 10:1 notation means ten parts raw leaf were concentrated into one part extract, so a small dose carries more plant material than the milligrams suggest. Mullein's traditional preparations and constituents (saponins, mucilage, flavonoids) are covered in our deep dives on mullein leaf benefits and mullein tea.
Ginger Root Extract (Zingiber officinale)
Among the most researched botanicals in the world. Ginger's gingerols and shogaols are studied for supporting a healthy inflammatory response, and the root has millennia of warming, soothing use across Asian traditions — see the science on ginger and airways. It also carries the formula's one meaningful interaction caution, noted below.
Organic Lemon Extract (Citrus limon)
Certified-organic citrus extract contributing bioflavonoids — plant compounds with antioxidant activity — plus the clean taste that makes the daily spray pleasant. More in our lemon extract breakdown and citrus bioflavonoids explainer.
About That “Proprietary Blend” Label
A proprietary blend discloses the total (154 mg) but not each herb's share — that is a real transparency trade-off, not a detail to gloss over. It is also common and legal across the supplement industry. We explain how to read such labels critically in proprietary blends explained and what 154 mg means in practice.
Inactive Ingredients — and Why Each Is There
- Purified water — the liquid base of the spray
- Glycerin — plant-derived carrier that keeps extracts dissolved and adds mild sweetness
- Natural flavors — rounds out the lemon-ginger taste
- Citric acid — balances pH and freshness
- Potassium sorbate & sodium benzoate — standard food-grade preservatives that keep a water-based liquid safe for its full shelf life
No stimulants, no melatonin, no artificial colors. The formula is non-habit-forming.
Cautions & Allergen Notes
Ginger can enhance the effect of blood-thinning medications — anyone on anticoagulants should clear it with their doctor, as should anyone pregnant, nursing, under 18, or managing a respiratory condition. Citrus-allergic users should note the lemon extract. Full details: side effects & safety and supplement–drug interactions.
