How mullein appears on the label
The proprietary blend lists mullein extract (Verbascum thapsus) leaf and wild-crafted mullein leaf as separate entries. Their individual amounts are not disclosed.
Traditional use is not the same as clinical proof
Mullein is commonly discussed in herbal traditions in connection with respiratory comfort. Cleveland Clinic notes that although mullein has long-standing folk uses and promising laboratory properties, rigorous clinical evidence in humans is limited.
What can responsibly be said
Traditional use can explain why a plant is included in an herbal formula, but it should not be converted into a claim that the plant — or Breathe — can treat asthma, COPD, pneumonia, chronic bronchitis or another disease. That would require disease-specific clinical evidence.
The strongest product-specific fact is that two mullein preparations appear on the label. Everything beyond that should be framed as general ingredient background.
Safety and quality
Botanical preparations vary in purity, extraction method and concentration. People who experience an allergic reaction or other unexpected symptom should stop use and seek appropriate medical advice. Do not inhale plant material or substitute supplements for prescribed respiratory treatment.
