Avoiding chemical air freshener. trying fresh waveessences of pine needle, clove, anise, and cedar. cough/cold cresting? or am i adding allergens?

U r adding irritants: to your already inflamed airways, better avoid those irritants till you sort out what kind of inflammation you have, whether allergic or non-allergic chronic inflammation, meanwhile use saline nasal washes often. See an allergist/Immunologist for evaluation, check aaaai.org, or acaai.org for an allergist in your area, good luck
