The page talks about everyday breathing concerns rather than diagnosed conditions, and the word occasional matters.
Occasional congestion points to an ordinary, now-and-then experience such as seasonal changes or a dusty room. It is not the language of a medical condition, and the FAQ says plainly that the product is not intended to diagnose, treat, cure or prevent asthma, COPD or any diagnosed respiratory disease.
Treat the wording as a statement about who the product is aimed at: generally healthy adults wanting daily support. If your congestion is frequent, persistent or comes with other symptoms, that is a question for a clinician, not a supplement page.
